Firefox Community Forum

Hello, Since yesterday, the Firefox web browser crashes systematically. This has happened well over a dozen times. I've tried multiple step-by-step solutions: deactivating extensions, troubleshooting mode, repairing firefox, uninstalling and installing Firefox, trying several versions of Firefox (Quantum, ESR, Nightly), downgrading to an earlier version, uninstalling and completely cleaning Mozilla folders on AppData, deactivating graphics/hardware acceleration...

At one point, Firefox was crashing after ten seconds of watching a video on Youtube or another platform. After reinstallation, video playback no longer causes the browser to crash, but closing a tab does.

I am currently using Mozilla ESR 115.12.0. After reinstalling, I lost all the reports I sent. Nevertheless, I was able to reproduce the crash to give you the ID: [https://crash-stats.mozilla.org/repor.../a2d0f5de-d03f-450b-88f8-a8fdc0240705] Another crash report : [https://crash-stats.mozilla.org/repor.../71c602f6-c682-4158-9880-24d6a0240705]

According to the crash table, the reason for the crash is as follows: EXCEPTION_STACK_BUFFER_OVERRUN / FAST_FAIL_GUARD_ICALL_CHECK_FAILURE This reason appears on all crashes.

Thank you.

Hi,

more Details concerning the problem you can see here ! It should be great if you could help us with some diagnostics, for example why the problem only appears with FF on Linux, not with FF on WIN.

STR:

1. Launch Linux FF
2. Visit this page "Potential issue with plugin PITM" (Preview here
3. Because you will need an Account for visiting account please follow "Konto eröffnen" (Create Account) instructions).
4. After my approval for the account please visit again "Potential issue with plugin PITM"
5. Click "1.png" Below heading "Attachments", that should work without problems.
6. Close image view
7. Move Mouse pointer to image below heading "My test with a screenshot" – should become magnifier
8. Now Click that image

  » Expected (and so it does with WIN): Big image opens in new TAB
  » Actual:  New TAB opens, but without image view.

What are your results? FF Linux Problem or something else?

I'm using Firefox 126.0.1 (64-bit) in Windows 11. I needed to download two files named index.html (in different source directories) from my company's content management system. Both got downloaded as index.htm. They were the right files... only the extension was changed.

I spoke to the person who maintains the content management system. They tested it and said it's not doing that, must be the browser.

That sounds fantastic to me, but I looked through the support messages here and found several about files whose extensions were changed on download; for example from .loa to .mp3. No explanations or workarounds, though.

Can anyone shed light on this?

Hi MFirefox

I'd like to cancel Relay. I have been having problems with getting logged onto sites that I need quickly. This morning Norton would not let me on to see my privacy report.

Please tell me how to delete/cancel Relay.

Thanks, [email removed]@frontier.com

this is definitely a unique issue i have not ever had, LOL

i'm running into a very strange issue where only the roblox page is not loading properly. everything else seems to work just fine; trying to load roblox on google chrome works fine too! ive turned off my extensions and run it in troubleshoot mode, i've updated the browser and my pc and my drivers, nothing seems to want to fix it. i'm not very sure what's going on. it's very funny, but definitely troublesome- the website is not navigatable in this state.

it randomly popped up like this last night, i was under the impression roblox itself was down because my friend in the call at the time had been talking about how slow the site is. upon digging deeper and asking around, nobody else is having the issue i'm having so i'm lead to believe its a me issue

Hi, To who it may concern, a big thank you. I am a longtime Linux Firefox user. I had a secondary password, but somehow it has been deleted. I have changed my primary password and I have full access to Gmail, Youtube and other Google pages. My email address has always been the same for many years. It is recognised by Firefox when I type "My account on Firefox" though I am not allowed to enter another secondary email address.

I am almost 80 and not very computer literate.Kind regards,

Patrick Van Niekerk.

Dear Sir or Madam,

Once again, Firefox is blocking my ability to go into X (Twitter). I'm guessing you guys did an update and changed the settings again. PLEASE FIX. Thank you.

Sincerely, Britt

Hi I have lost all my bookmarks. I bought a new device. On downloading Firefox the the bookmarks toolbar was Google's. Now Firefox on my other devices has the the Google bookmarks toolbar. Help please.

When I use google meet, I regularly get feedback that I sound far away, despite being at a normal distance from my computer. If I switch to another app, like slack, the issue doesn't present (so it's not an OS level issue). I'm using firefox on m3 macbook pro.

What can I do to fix this issue? Or do I have to stop using firefox?

i recently made a firefox account synced the data cuz i was getting a new pc. Then when i went to login with the same account none of my bookmarks, passwords or anything was there. It just gave me a fresh account.

Hello, i want to know if i can use dark mode in the main web sites of mozilla, like support page or account page, becase it hurts my eyes when i want to switch from other sites where i at least can use some extension to fix it but all mozilla pages always bright white. What i have to do? Thanks

Updated my Win 11 laptop with latest changes and find the fonts on pages and on tabs is all messed up. I've tried Settings to choose larger size, set defaults to Arial and/or Arial Round .... does not help.

How do I either fix this, or undo this update, or is there a fix coming ASAP??

Hi! When I bring up my Firefox browser it automatically shuts down and comes up again with two issues: 1. Do you want to restore pages? 2. A red striped URL with the little robot and the error message: browser is under remote control reason devtools

I've read all the postings and I don't understand many of what they are suggesting and those that I do, don't work. Please help p.s. I've already downloaded the newest version.

I keep getting intrusive mozilla / Mcaffee advertising banners on my screen when firefox is open. avast won't stop them. It only affects my new dell laptop windows 11 computer. It looks like the code for firefox has been invaded. How do I block updates to firefox or get ride of the adds?

Google search no longer works on Firefox. Other browsers have no problems. Changing the default search engine on Firefox works (eg Bing), BUT. It can now find Google Maps, but Google Maps cannot find a location, because it uses a Google search. I tried the fix in about:config, but it had no effect.

In Chromium you can go a page backward or forward by swiping one finger to the left or right. This works really well. I have been missing this feature in Firefox for years now. Without it navigation in the browser is tedious on Linux tablets or phones.

Is something similar ever going to be implemented?
