While following this step in order to reduce CPU and memory consumption of firefox [content-prefs.sqlite file], I accidently deleted the Profile folder itself.

After this firefox wasn't opening and was stuck on not responding in activity monitor.

I reinstalled firefox, multiple times even after a shutdown, removing any old files in the Library folder. Still it's stuck on the same issue, firefox doesn't opens up even once.

Hello there, for past few days I'm having issues mainly on Twitch.tv - the streams do work fine, but whole website is displayed as text - Avatars, emotes, badges are displaying as text, or don't display at all, I'm attaching screenshots as examples. What I've tried - restarting PC, router, full re-install of Firefox, disabling all add-ons and uinstalling them (7tv and FFZ), private mode, troubleshooting mode, creating a new profile in Firefox, checked firewall settings, checked AV settings and did multiple scans - nothing was found, tried changing Firefox security Settings, also cleared cache and cookies.

I think that's everything - I was doing everything that was in the article: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems

Regarding other websites - this is completely random, mail works, some websites also do, but on some it gets stuck, like for example when I have to do a 2FA somewhere and get a pop-up window to click "login" or type a code, it just gets stuck and nothing shows up.

Not sure if this helps, but exactly same issues appear on different browsers - Chrome, Edge, but only on PC. I tried Firefox on mobile and it worked just fine.

If I can provide more details please let me know, I did attach the "Troubleshooting Information" so hopefully this also helps.

Thank you in advance!

There's not really much skirting around it. Yesterday, I came across this sudden error with my Firefox browser on PC (see annexed image), which basically rendered me unable to open it for some reason. It did get fixed that same day somehow, though for a short while, as I was faced with the same error message again today and once again haven't been able to open my browser, much to my frustration.

I tried searching about it on the internet, but didn't find anything of help – most videos about it refer to a mistake on the Windows OS with the same code (0xc000185); asking around to people I knew didn't do much, either.

Today I tried a bunch of stuff to see if it resolved my problem in any way, such as: 1. Restarting my laptop (didn't work); 2. Installing both suggested and optional updates available to my Windows version (put me at ease a little, but still didn't work); 3. Searching for malware (antivirus didn't find anything, so I'm thankful this one didn't work); 4. Verifying system files with 'sfc /scannow' (all was good, so it didn't work);

I was also going to try doing a 'chkdsk /f /r', but I didn't have time to, as I had to leave for something. There are also other things such as creating another profile, which I'm considering; updating Firefox, which I can't do because I can't open the browser to check if there are any updates; and reinstalling Firefox, which I'm slightly afraid to do and will leave as a last resort because I don't want to risk accidentally doing it wrong and losing all my history, bookmarks, etc.

Any help would be incredibly welcomed. Thanks in advance.

P.S.: The text on the error message reads (translated from PT-BR): "The app couldn't be started correctly (0xc0000185). Press OK to close the app." Sorry if the photo isn't very good.

I was browsing a webpage that turned out to be in Portuguese, and I was looking for how to translate it, but the internet indicated that Firefox has built in transation! However, neither the Translate Toolbar Icon nor the Translate menu option appear, even if I visit a site that absolutely should be translatable (https://fr.wikipedia.org/wiki/Mozilla_Firefox)

Additionally, if I go to Settings -> General, there is a Translations section, but if I click the Settings button, there are no languages in any of the boxes and no option to add any.

I am on Firefox 126.0 for Windows.

Here are the things I have tried:

• Restarting Firefox
• Rebooting my PC
• Disabling all my extensions
• Running Firefox in Troubleshooting Mode
• Clearing my Startup Cache
• Performing a "Refresh Firefox"
• Toggling and Untoggling browser.translations.enable and browser.translations.automaticallyPopup

Does anyone have any suggestions of something I could have missed?

Hello, about 1-2 weeks ago a very strange problem occurred - on some pages videos don't play at all or play without a sound. Can anyone help me with this strange situation? For example, every video on youtube.com plays without a problem; on facebook.com every video plays with no sound at all; on some other pages video doesn't play at all. This problem is only with firefox, if I try to open the same videos with another browser everything is fine.

When logging into a Wordpress site on Firefox, hovering over Username displays a gear (see first screenshot) which when clicked on exposes passwords and allows them to be edited (see second screenshot). This does not happen on other browsers. I'm on Firefox 126.0, MacOS Big Sur 11.7.10

I am trying to remove the mobilisearch.com virus from my Firefox browser. I have tried a reset and have also tried the Zemana virus removal tool. Neither have worked. Any suggestions please

Hi there, Can anyone help me please. Ive been using Firefox forever and yesterday I signed into a Gmail account to send an email to someone, I typed in who it was to, then subject and then when I went to type into the body of text, the keyboard wont work.

I thought there was an issue with the keyboard but I then I tried to type in issues on firfox and loads of text is missing, I basically cant use firefox at the moment as Im only viewing half the info.

Ive been sent a credit not from someone and this is what its viewing like.

I didnt change anything that Im aware of

Thanks and fingers crossed in anticipation. Andrea

Firefox uses about half a gig on my disk, that's: '~/.mozilla' and '~/.cache/mozilla' can that be reduced? Either some setting that limits disk use or even a manual deletion of ancient stuff?

Whenever I use the picture in picture feature, it always opens up in a bigger tab instead of the floating PiP. I am unable to adjust the sizing whatsoever. Is there a way to get around that?

I hve discussede the matter with my banks IT-department, but they answer me that recently they have heard about the same problem concerning Firefox login and said that the problem have to be fixed by Mozilla/Firefox

I'm unable to open pdf in mozila as it is showing access denied in acrobatservices.adobe.com in the all other browser its opeing perfectly please fix this issue vfast

YouTube content doesn't load. Same with NYTimes.com articles.

Up to date, no extensions, no add-ons.

Running Sonoma 14.4.1

Safari and Chrome work as expected.

I usually download and install manually the custom install of Firefox on Windows.

Recently, a new version was automatically installed without my permission and destroyed all my customization. THIS IS UNACCEPTABLE. I had to restore the older version from backup and I was going to stop updating.

But I see that the manual custom installation is still available for download.

I want to make sure that if I use it it will not wipe out my customization again.

Please confirm.

We have a noticed a very strange behaviour with the latest FireFox (126). One of our webpage is behaving differently across our Integration and production environment. Both env are running identical code and similar network stack the only difference we have noticed so far is for our Integration env Firefox is sending the different user-agent string than for production.

Steps to reproduce: 1. Open https://integration4-view.publitas.com/automation-int4/reader-happy-path/page/1

2. Go to console and view navigator.userAgent the user-agent string will be:

    "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:126.0) Gecko/20100101 Firefox/126.0" 

3. Now open the same content on production -> https://view.publitas.com/automation-prod/reader-happy-path/page/1

4. Go to console and view navigator.userAgent the user-agent string will be:

   "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) FxQuantum/126.0 AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.5060.71 Safari/537.36" 

Our website changes behaviour based on which browser it is and based on second string our backend interprets the browser as chrome instead of Firefox.

If I change privacy.resistFingerprinting to True then the user-agent string is sent correctly.

Can you please help us identify what changed in the latest version that is causing this behaviour.

Version: 126 (64 bit) Test on Windows 11 and Mac OSX

Firefox is synced on all my computers. Same version. Same extensions. I can't login on my primary desktop as of last night 5/23/24. I can login/watch Prime on my laptop. My desktop gives me the attached error.

Firefox Desktop issue,

McAfee malware has entered the Firefox browser a couple of days ago claiming viruses have been detected & requires me to click on their popup to remove it. Additional warning follow and reoccur every couple of minutes. I don’t have McAfee Anti-virus software on my computer & have not installed any new software for some time. The anti-software I have works fine (Spybot & Microsoft Security Essentials) and detects no problems. The first application I initiate upon boot-up each morning is Firefox and that’s when the problem begins. It is somehow related to Firefox. I cannot find any processes in play.

I’m using Windows 7 Pro

Sincerely, [removed email from support forum]

I tried all six free malware scanning programs suggested but nothing found

The plus sign in the tab bar has always been on the far right side. I reloaded Firefox yesterday and now the plus sign is directly after the tab. How do I get the plus sign back to where I like it?
