Firefox Community Forum

One of the things I like most about Firefox is the home page with 'tiles' for my most used websites. Since the last upgrade some of my tiles have the website logos but most do not. Is there a way I can fix this?

Firefox tab crashes whenever I try to open Firefox. I have AOL and Firefox browser. I've tried the close and reload, restart laptop, and redownloading Firefox to no avail. However, I was able to open my AOL and email. I reached this help page using Edge.

The tab group suggestion feature is unavailable for me, even though I am on Firefox 145.0 (64-Bit on Windows 11 Pro 25H2). I tried using guides like [one from mozilla] https://www.askvg.com/enable-or-disable-new-ai-powered-smart-tab-groups-in-firefox/ this external about:config editing guide.

The latter does changes to the about:config. A screenshot of my settings, my config, and my Add-ons is attached.

I do not know what is wrong.

When i try to fullscreen youtube, there is a transparent border on the left and top of the window that will not go away normally. The only temporary fix I found was pressing win+d twice to get rid of it. This seems to be a reoccurring issue as this only happens on firefox and nothing else. This reddit post helped me. https://www.reddit.com/r/firefox/comments/13eguvp/please_help_transparent_video_border_when_in/

Please let me know how to fix this permanently. I have also tried firefox safe mode and that curiously didnt have borders but even when i went out of safe mode and disabled all my extensions and cleared my cache, it didnt work.

No matter what I try to read or go to, Firefox crashes repeatedly. I literally cannot use it at all. I keep getting: Gah. Your tab just crashed. We can help! Choose Restore This Tab or Restore All Crashed Tabs to reload the page/pages.

Clicking those options fixes nothing! How do I go back to the previous version, please?

I ran a Windows 11 Update and after I opened Firefox, it shows all the tabs that were there but each tab indicates that it's 'Crashed'. The 'Tab Crash Reporter' doesn't restore a single tab nor does it react to 'Restore all Tabs'. It looks like Firefox is NOT connecting to the web.

I'm entering this using the Edge browser.

Thanks in advance, Bob

When I am on some webpages, and want to copy and paste a paragraph, of course I highlight it first -- but as of a couple of days ago, the links to pop-up boxes on the page will not highlight. If I go to the same page with Chrome, there is no problem. I can highlight links to other webpages, it is just the ones to pop-up boxes. I have checked and this problem is not machine-specific. I am on a laptop and I checked our desktop and it has the same problem. Perhaps the recent update changed something? I have attached a screenshot of a page from Ancestry.com with the problem -- on the left I have tried to highlight the whole thing, and, as you can see, the links are not highlighted, and if I copy and paste, the links do not work. Thanks for any help you can offer Jeanne

Hi, after the last update I got this message that resides above my browser window:

The security sandbox is disabled. Your configuration is unsupported and less secure

I'm on Windows 11.

Apologies if this is the wrong place to ask this because I'm at my wits end on this one. I work on an app that is used by a large amount of users. Starting october 14th around 7am (UTC+1) we started observing weird behavior where a small ammount of traffic (less that 1%) would have abnormal header values:

'custom-header-1':'[custom value], [custom value of a different header]'; 'custom-header-2':'[custome value of header 2], u=4'; 'sec-fetch-site':'cors'; 'priority':'same-origin'; 'sec-fetch-mode':'empty';

As you can see the values of these headers are mixed with one another in almost a deliberate manner (since it appended the u=4 with a comma separator and a space from the priority into the custom header 2 value). There is nothing in the client code that would do this kind of manipulation, and from examining the logs this only happens on Mozilla browser traffic starting version 144 (which was released on October 14th coincidentally). Not that this does not impact all Firefox traffic. In fact, just a tiny fraction of traffic from random users and it's not even all of their traffic of an active session. Just random requests that then fail, are retried and the abnormal headers are gone.

I doubt the fault lies in firefox. If I had to hazard a guess it's probably some extension acting up, but the timing coinciding with the release of 144 give me the only troubleshooting path I have right now since contacting the users is not possible. We've seen it happen 145 as well.

I'm not really looking for a solution here, just a shot in the dark if someone else has experienced this or has some insight as of what this could be.

This is where you describe the issue in detail.

Explain what’s happening (e.g., “Videos keep freezing after 10 seconds”).

Mention when it started and what you already tried.

Include your Firefox version (you can find it under Menu → Help → About Firefox).

Hi! So I just installed firefox and I got onto annoying issue. I like using shortcuts on my homepage, but I started to get some shortcuts added automatically and they bother me a lot. I tried removing them or deleting from history, but as soon as I click the button, one shortcuts gets removed and immediately gets swityched with another one automatically. So I'm stuck in the infinite loop of removing shortcuts and my manually added ones just get lost in all this mess.

At about 9 AM EST, 11/12, Firefox did an update that rendered accessibility through my voice navigation software inoperable. I need to use this to navigate the web due to disabilities with my hands. The system could no longer recognize any thing buttons or words on webpages, including the Firefox tabs at the top left of screen. I posted a question about this on 11/13. Later that afternoon, the functionality was restored. However, this morning, 11/13, this functionality has vanished again. Can this please be restored? Something obviously went awry in the coding with this most recent update. Thank you.

Hi. Both my wife and I are experiencing page load problems on Firefox in the last 24 hours or so.

Many pages, but not all, are loading very slowly, and sometimes taking minutes. The spot in the tab keeps moving (left, right, etc), and when it stops, the page is loaded or in some cases just totally blank. On one occasion the was a message about, i think, a protocol error.

We are both on separate Windows 11 machines, rinning Firefoz browsers v145.0, and it seems that the problem is since the upgrade. We use different Anti-virus software. I have cleared all cached data and disabled the only extension added, namely Lastpass.

Attempting to load the problem pages in Chrome works normally. (e.g. https://developer.wordpress.org/plugins/)

Is there a problem with this version, or is there another explanation?

Hello Since last update (145), I'm experiencing an issue where Firefox becomes unable to access the internet following a temporary loss of connection during the normal use, until I completely quit and reopen the browser.

I'd appreciate any advice on how to resolve this.

Thanks
