Firefox Community Forum

Since a few weeks I have been encountering an issue where tabs in Firefox would frequently crash. I do have various add-ons installed, however I haven't installed any new ones around the time the issue has been occurring. I've been unable to track down which add-on or if any add-on might be causing this.

Trying to search for this issue all I could come up with is that it might be an issue of a faulty CPU. I have an i9-13900KF which has been known to be part of the Intel generation with serious flaws. However I already installed a BIOS update and applied Intel's recommended settings to undervolt the CPU to prevent any issues. This was well before the Firefox tab crashing issue happened. So I'm not sure if it can really be the issue of a faulty CPU, but I've also had issues of other programs randomly crashing recently (like Discord or Steam).

The tab crash can occur on any website, for example Youtube, Duckduckgo, Protonmail, etc. The crash reason always is either "EXCEPTION_ACCESS_VIOLATION_READ" or just "EXCEPTION_ACCESS_VIOLATION". The crash also most of the time (but not always) occurs when loading the page itself or a video / live stream on it. But not when browsing an already loaded page (for example this forum post page I'm writing right now).

Here are some of the crash reports I've submitted:

EXCEPTION_ACCESS_VIOLATION_READ: https://crash-stats.mozilla.org/report/index/60309ae8-8cad-43ac-8b9b-172b10250815 https://crash-stats.mozilla.org/report/index/fecef0ab-d874-4cb5-990b-e49650250815

Rather rare "EXCEPTION_ACCESS_VIOLATION": https://crash-stats.mozilla.org/report/index/114b26fa-4e10-442c-bbd5-406630250812

Could someone help me narrow down this issue? Can it really be a faulty CPU and I need to trade mine in?

I have recently installed the containers extension and have been having a bit of trouble with one site (the others are fine), which seems to originate from the manner in which the site is structured. As it references new pages, they are often in a different URL. For example, you start in login.site.com, which then tries to load dashboard.site.com, but it fails authentication on dashboard.site.com because it opens in a different container. Which then tries to open the login.site.com page again, which displays the login page, but showing it tying to complete the original authentication. I have tried to add each step along the way, but without success. Is there a way to overcome this?

I have Marionette mode enabled to be able to remote control my Firefox, but I have trouble with some sites who believe I'm not human.

If I enable Marionette, then go to this site, I can't get past the Human verification.

Can sites detect that I'm using Marionette?

How do I update Firefox to perform like it used to before the last update. Firefox on my laptop cuts off the right side of the selection box so I can't select 2nd step, text, email, or password and continue doesn't show. It works in Chrome, not in Firefox.

Just updated to FF 141.0.3. The browser had advised me to restart to finish the update. So I did. But in doing so, not all my tabs were recovered.

Most were, but like 3 were not.

My wife and I have email accounts with proton on our previous computer with Windows 10 The new one has windows 11. She can sign in to her email -no problem. I'm told "incorreet credential"! But same one used for years, and still works on "old computer" Many companies use that email. How do T get to it on the new one?

I was trying to customise my browser settings, decided I didnt like any of the changes,and wish to get back to where when I open firefox it shows shortcuts to my most recent, or most used places. How do I return to that setting?

Thanks.

I installed a voice recognition feature on my Replit-built app, and when I activated the app, I received the error message: 'Your browser does not support voice recognition. Is there any version of Firefox that supports voice recognition?

When I log into apps and other sites FF is displaying and recommending current and/or old login information. I do not want FF to make any login recommendations for me.

For some reason, starting since last week, whenever I try to upload something online, instead of opening the most recent folder I uploaded from like it used to, Firefox keeps opening the same folder. Although, for some reason, this mainly happens on YouTube. Is there a fix for this?

Lately I’ve noticed firefox slowing down a lot on certain small game sites. for example, I was doing a daily word puzzle on spellbeegame.com and after like 10 minutes, it started lagging so bad I could barely type in letters.

I cleared my cache, disabled a few add-ons, even restarted the browser — same issue. The weird part? It works perfectly fine in chrome.

Is firefox just bad with these interactive game pages? or is there some hidden setting I’m missing? Would love to get it fixed because I actually prefer using firefox, but the stutter kind of kills the fun.

anyone else had this happen?

I have lost my History and Bookmarks. A message appears 'The bookmarks and History system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem' I use Asast One and Malwarebytes. Can you help please? I am not very technical so if you can put an answer in very basic terms that would be appreciated. Thank you. Arthur Moody

I visited the following site: Broker I can see their favicon in the tab. I bookmarked it to the Bookmark Toolbar, but the favicon is not the same (See image).

I did some search on this in google but nothing helped (refresh it, delete the favicon sql file, devtools chrome enabled, etc). I thought that firefox will honor the absolute path in the website. The following code is from the web site (I used the developer tools to inspect it).

<link id="dynamic-favicon" rel="shortcut icon" href="https://content.client.bnc.ca/content/dam/orion/favicon.ico">

If I edit that line to remove everything before the favicon.ico word, I get the incorrect icon.

This is not an issue in other browsers, but I only use Firefox at home.

How can I solve this? Hopefully without using an extension. Thanks

Seit dem letzten Firefox-update wird alles in allen Bereichen nur noch in English dargestellt, obwohl in "Einstellung" Deutsch ausgewählt ist. Firefox ist mein Hauptbrowser. Mein Betriebssystem ist win 11 home

When the above add-on is activated it seems like the process is hanging. The Webadvisor icon flashes about once in a second. Is there a better solution than to desactivate it? Thank you for comments.
