about:blank and about:blank#blocked Explained – What It Is, Is It Safe, and How to Fix It

If you just saw “about:blank” or “about:blank#blocked” appear in your browser, take a breath – it is not a virus, and your computer is not hacked. Here is exactly what it means, why it appears, and what you should do about it.

Quick answer: about:blank is a built-in blank page that every web browser has. It shows up when the browser has nothing else to display. It is completely safe and normal. The #blocked version appears when your security software blocks a link before it loads.

1. What Is about:blank?

about:blank is a blank page built into every web browser. It is not a website, and it does not load from the internet. It lives inside the browser itself.

The word “about:” at the start is a special browser command – kind of like an internal address that tells the browser to do something or show something from its own settings rather than fetching a page from the web. You can try it right now: type about:blank in your address bar and hit Enter. You will see a completely empty white page – no content, no ads, nothing.

Browsers need to always display something in their window. When a browser cannot figure out what to show – maybe a page failed to load, or you just opened a new window – it falls back to about:blank as its default empty state.

That is literally all it is. A blank page. Nothing scary.

You might see about:blank in several normal situations:

• Opening a brand new browser window or tab before a page loads
• When a link fails to load due to a slow connection
• After a download starts, when the browser opens a blank tab alongside it
• When your browser is set to open with a blank page on startup
• After removing malware, when your browser’s homepage gets reset

2. Is about:blank Safe? Is It a Virus?

No. about:blank is not a virus, not malware, and not spyware. It is a normal, built-in part of every browser including Chrome, Firefox, Safari, Edge, and Opera.

A lot of people assume it must be malicious because it looks strange. But it is no different from other built-in browser pages like about:settings or about:newtab – it just happens to show nothing.

However, there is an important nuance worth understanding:

about:blank itself is safe, but sometimes seeing it unexpectedly can be a sign that something else went wrong. Here is the difference:

Normal reasons to see about:blank:

• Your browser is set to open with a blank page on startup
• You opened a new tab before a page started loading
• A download started and opened a blank companion tab
• You typed about:blank in the address bar yourself

Potentially suspicious reasons:

• Your browser used to open with Google or another homepage, but now it always opens with about:blank – and you did not change this setting yourself
• about:blank keeps appearing in new tabs or pop-up windows that you did not open
• You recently had malware on your computer and removed it

In the second set of cases, about:blank is not the problem – it is a symptom that your homepage settings may have been changed by malware. The blank page appeared because your browser lost its homepage setting and had nothing else to show.

The solution in those cases is not to “remove” about:blank – it is to find and fix the underlying cause.

3. What Is about:blank#blocked?

This is the version that tends to confuse people the most, especially if it appears suddenly in a tab.

about:blank#blocked is what your browser shows when a security tool – your antivirus, parental controls, a browser extension, or a built-in browser safety feature – blocks a link before it can load. The browser tried to open a page, that page was blocked for security reasons, and the browser had nowhere to go, so it displayed about:blank. The #blocked part was added to signal that something was blocked.

The hashtag (#) symbol here is a page element reference, not a hashtag in the social media sense. It is the browser’s way of saying: “I am showing you about:blank, and the reason is: blocked.”

Common causes of about:blank#blocked:

• Your antivirus (Windows Defender, Avast, Norton, etc.) blocked a malicious link before it loaded
• Parental control software blocked a website based on content filters
• A browser extension like uBlock Origin or AdGuard blocked an ad or tracker that tried to open a new window
• Chrome or Edge’s built-in Safe Browsing feature blocked a phishing or malware site
• A corporate network or school network firewall blocked the destination

Is about:blank#blocked dangerous?

Usually the opposite – it means your security software did its job. A malicious or unwanted page tried to open, and something stopped it. Seeing about:blank#blocked after clicking a suspicious link is actually a good sign.

If you see it regularly when browsing normally, it could mean:

• A website you visit has ads or scripts being blocked by your browser extension
• Your security software is set to a strict filtering level
• Your browser’s security settings are enabled (which is good)

What to do: If about:blank#blocked is appearing constantly on normal websites you trust, check your browser extensions (click the puzzle icon in Chrome and review what is installed) and review your antivirus or parental control settings.

4. Why Is about:blank Appearing? Causes and Fixes

Here are the four most common reasons about:blank appears – and exactly what to do about each one.

Cause 1: You Set It as Your Homepage and Forgot

This is more common than you think. You or someone else set the browser to open with a blank page a long time ago, and you forgot about it.

Fix: Simply change your homepage back to whatever you want. See the browser-specific steps in Section 6 below.

Cause 2: Malware Changed Your Homepage Settings

Some malware and browser hijackers tamper with your browser settings. When you remove the malware, the homepage setting it forced gets deleted – and your browser is left with nothing to show, so it falls back to about:blank.

Fix:

1. Run a full scan with your antivirus software or Malwarebytes (free version works)
2. Once the scan is clean, manually reset your homepage in browser settings
3. See Section 7 for how to check if malware caused this

Cause 3: A Bad Browser Extension Is Interfering

Some extensions — especially ones you may have accidentally installed – can interfere with your browser’s homepage setting. Toolbars, PDF converters, and download managers are common culprits.

Fix:

1. In Chrome, go to chrome://extensions in your address bar
2. Look for any extensions you do not recognise or did not install intentionally
3. Click “Remove” on anything suspicious
4. Restart your browser and check if the issue is resolved

Cause 4: Browser Settings Were Corrupted or Reset

Sometimes a browser update or a crash can reset settings back to defaults. If your default settings had about:blank, that is what you will see.

Fix: Simply go into your browser settings and set your preferred homepage. The steps for each browser are in Section 6 below.

5. How to Remove about:blank – Browser-by-Browser Guide

“Removing” about:blank means changing your homepage or new tab setting back to what you want. Here is how to do it in every major browser.

Google Chrome (Windows and Mac)

1. Click the three-dot menu in the top-right corner of Chrome
2. Click Settings
3. In the left sidebar, click On Startup
4. Select Open a specific page or set of pages
5. Click Add a new page and type your preferred homepage (e.g. google.com)
6. Delete the about:blank entry if it is listed by clicking the three dots next to it and choosing Remove

To also change what appears when you click the Home button:

1. Go to Settings → Appearance
2. Toggle on Show Home Button
3. Select Enter custom web address and type your preferred URL

Mozilla Firefox (Windows and Mac)

1. Click the three-line menu in the top-right corner
2. Click Settings
3. In the Home section, find Homepage and new windows
4. Click the dropdown and choose Custom URLs
5. Type your preferred homepage URL in the box
6. Close the Settings tab – changes save automatically

Apple Safari (Mac)

1. Click Safari in the menu bar at the top of your screen
2. Click Settings (or Preferences on older macOS)
3. Click the General tab
4. In the Homepage field, delete about:blank and type your preferred URL (e.g. https://www.google.com)
5. Click Set to Current Page if you want to use whatever page is open right now
6. Close the Settings window

Note: The correct entry in Safari is about:blank – not “About: Empty” as some older guides say. Safari accepts about:blank directly in the Homepage field.

Microsoft Edge (Windows and Mac)

1. Click the three-dot menu in the top-right corner
2. Click Settings
3. In the left sidebar, click Start, home, and new tabs
4. Under When Edge starts, select Open a specific page or pages
5. Click Add a new page and enter your preferred URL
6. Remove about:blank from the list if it appears

To change the Home button URL:

1. Still in Start, home, and new tabs, scroll down to Home button
2. Toggle it on, select Enter URL, and type your preferred address

Chrome on Android (Mobile)

1. Open Chrome and tap the three-dot menu at the top-right
2. Tap Settings
3. Tap Homepage
4. Toggle Homepage on if it is off
5. Select Enter custom web address and type your preferred homepage

Safari on iPhone (Mobile)

Safari on iPhone does not have a traditional “homepage” setting the same way desktop browsers do. However, you can control what appears when you open a new tab:

1. Open Settings on your iPhone
2. Scroll down and tap Apps, then tap Safari
3. Under General, tap New Tab Page
4. You can turn off or on the various elements that appear on new tabs (Favourites, Siri Suggestions, etc.)

If about:blank keeps appearing on your iPhone Safari, it is most likely because of a link that failed to load or a redirect that was blocked – not because of a settings issue.

6. How to Set about:blank as Your Homepage (And Why You Might Want To)

Some people deliberately set about:blank as their homepage, and it is actually a smart choice for a few reasons.

Why use about:blank as your homepage:

• Faster browser startup: Fetching a homepage like Google or a news site takes a moment. about:blank loads instantly because it does not contact the internet at all
• Saves bandwidth: If you are on a metered connection or slow internet, starting with a blank page means you only load pages you actually choose to visit
• Privacy: When your browser starts, it does not send any requests to Google, your news site, or anywhere else. Nothing is tracked just by opening the browser
• Clean start: Some people prefer a blank canvas – they type the URL they want directly rather than seeing a cluttered new tab page

The downside: You lose quick access to bookmarks, frequently visited sites, and news feeds that appear on a typical new tab page. If you rely on those, about:blank might feel too bare.

Use the browser-specific steps in Section 5 above, but instead of entering your preferred homepage URL, just type about:blank in the page field.

7. How to Check If about:blank Was Caused by Malware

If about:blank appeared suddenly and you suspect something is wrong, here is a step-by-step process to check and clean your browser.

Step 1: Check Your Browser Extensions

Extensions are the most common non-virus cause of browser issues.

In Chrome: type chrome://extensions in the address bar. Review every extension listed. If you see something you do not recognise, or something with a generic name like “Fast Search” or “PDF Converter Plus” that you never intentionally installed, click Remove.

In Firefox: type about:addons in the address bar. Click Extensions in the left sidebar. Remove anything suspicious.

In Edge: type edge://extensions in the address bar. Same process.

Step 2: Run a Malware Scan

Download and run Malwarebytes Free (malwarebytes.com) – it is free to use for scanning and is widely recommended. Run a full scan and follow its instructions if it finds anything.

Windows Defender is also a solid option. Press the Windows key, search for Windows Security, open it, and click Virus and Threat Protection → Quick Scan or Full Scan.

Step 3: Reset Your Browser Settings

If you found and removed malware or suspicious extensions, reset your browser settings to clear any remaining changes.

In Chrome: go to Settings → type “reset” in the settings search bar → click Restore settings to their original defaults → click Reset settings.

In Firefox: type about:support in the address bar → click Refresh Firefox in the top-right.

In Edge: go to Settings → Reset Settings → Restore settings to their default values.

Step 4: Reset Your Homepage

After resetting, go back and set your preferred homepage following the steps in Section 5.

8. Other about: Pages in Your Browser

about:blank is just one of many built-in browser pages. Here is a quick reference for the most useful ones. You can type any of these directly in your address bar.

about: Page	What It Does
about:blank	Displays a completely blank page
about:settings	Opens browser settings (Chrome: use chrome://settings)
about:extensions	Opens extension manager (Chrome: chrome://extensions)
about:downloads	Shows your download history
about:version	Shows your browser version and build details
about:newtab	Opens the new tab page
about:history	Opens your browsing history
about:bookmarks	Opens your bookmarks manager
about:flags	Shows experimental browser features (Chrome: chrome://flags)

Note: In Chrome and Edge, some of these use the browser-specific prefix (chrome:// or edge://) instead of about:// – both usually work.

9. FAQs About about:blank

Is about:blank a virus?

No. about:blank is not a virus, malware, or anything harmful. It is a blank page built into every browser. However, if about:blank started appearing unexpectedly, it may mean malware changed your homepage settings. The solution is to scan for malware and reset your homepage – not to worry about about:blank itself.

What does about:blank#blocked mean?

about:blank#blocked appears when your browser tried to open a page but a security tool – your antivirus, a content blocker, parental controls, or the browser’s built-in safety feature – stopped it. The browser had nowhere to go, so it showed about:blank. The #blocked part indicates the reason. It usually means your security software did its job.

Why does my browser keep opening about:blank?

The most common reasons are: your browser is set to open with a blank page (check your homepage setting), or malware changed your homepage and was then removed, leaving your browser with no homepage. Fix it by going into your browser settings and setting a preferred homepage URL.

How do I get rid of about:blank?

Go into your browser’s settings and change the homepage to your preferred URL. In Chrome: Settings → On Startup → Open a specific page, then add your preferred address. Steps for all browsers are in Section 5 of this article.

Should I use about:blank as my homepage?

It depends on what you value. about:blank makes your browser start faster, uses no bandwidth, and is more private. But you lose quick access to bookmarks and frequently visited sites. It is a good choice for users who always type URLs directly and want a faster, cleaner start.

Does about:blank use any internet connection or bandwidth?

No. about:blank does not contact the internet at all. It is rendered entirely from within your browser with zero network requests. This is one of the reasons some users prefer it as a homepage – there is nothing to load.

Is about:blank the same in all browsers?

Yes. about:blank is a standard browser feature that works identically in Chrome, Firefox, Safari, Edge, Opera, Brave, and virtually every modern browser. The behaviour is the same across Windows, Mac, and mobile.

Can about:blank appear on my phone?

Yes. about:blank can appear in Chrome on Android and Safari on iPhone for the same reasons as on desktop – a link failed to load, a download opened a new tab, or security software blocked something. On mobile you cannot typically set about:blank as your homepage the same way you can on desktop, but seeing it occasionally is normal.

Summary

about:blank is one of those things that looks alarming but is almost always completely harmless. Every browser has it, and it is just a blank page your browser shows when there is nothing else to display.

The version you really need to understand is about:blank#blocked – that one specifically tells you something was blocked by security software, and seeing it means your protection worked.

If about:blank is appearing repeatedly and unexpectedly, the checklist is simple: check your browser extensions for anything suspicious, run a quick malware scan, and reset your homepage to what you actually want. That is usually all it takes.
