Firefox Community Forum

I just tried to open Firefox and got the message "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". DO NOT redirect to this link

It is useless. I tried to restore 3953 items from a previous back up and received the message "Unable to process the backup file".

I am not interested in hearing how to prevent this problem in the future, because obviously creating backups do not work.

How do I check to see if the problem was caused by security software, even though I have not added anything?

I'm getting the F7701-1003 error every time I try to play Netflix (works fine on other browsers). I tried every step of this guide this guide and triple checked it. I tried uninstalling, resetting profile, I that checked resistfingerprinting is turned on. I'm kind of at a lost. At this point I'm being forced to use other browsers...

For some reason I cannot type anything in Google Docs on the Firefox Desktop Browser. In fact, it seems like the browser doesn't recognize that I'm using Google Docs at all - in my attempts to see what was up I tried to bold a word to see what would happen, but the Ctrl + B shortcut opened the Firefox bookmarks tab instead. This is happening across all my Google Accounts, but only on Firefox and only in Docs - I can edit sheets and forms without issue, I can edit them all on my Android through the google apps, and I can edit them in another browser.

This is an issue that happened suddenly yesterday and I cannot think of anything that's caused it. I double checked that I had editing permissions on these docs, asked the people who owned them to remove me and re-add me but no luck. I have cleared cache and cookies, logged out and back, restarted the browser, and restarted my computer. Though I haven't changed anything with my extensions recently, I tried deactivating and reactivating everything I had. None of this caused any difference and I still cannot edit. I've also tried a user-agent switcher to see if that could help, but no dice. It really does seem like the issue is firefox not recognizing Google Docs is Google Docs and I'm not sure what the fix for that would be. Any advice would be greatly appreciated.

I've added https://x.com as an exception site but it is still blocked.

https://x.com/mozilla doesn't work either

Error message on the page:

"Something went wrong, but don’t fret — let’s give it another shot.

⚠️ Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com"

After 2 days it used to finally load without my doing anything, but not now. I never loads using Firefox.

https://x.com is added as an exception, but obviously ignored.

Tried You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

   hold down the Shift key and left-click the Reload button   

NOPE

Tried: Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.

"Remove the Cookies" for websites that cause problems:

   Settings -> Privacy & Security
   Cookies and Site Data: "Manage Data" 

"Clear the Cache":

   Settings -> Privacy & Security
   Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

   switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
   do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

NOPE - lost all my bookmarks, extensions, settings - not going there again thank you

as for:

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

   click the shield icon for more detail and possibly disable the protection 

the sheild has a slash thru it saying "enhanced tracking is off for this site" when i put my mouse over it.

I keep getting a browser error message on a site that I use almost daily. I have cleared cookies and cache and run the troubleshooter but still get the same message. Thanks.

Ik heb 5 dagen geleden firefox opnieuw moeten installeren omdat ik steeds een foutmelding kreeg. Volgens mij is er toen een en ander misgelopen. Ik ben mijn geschiedenis, bladwijzers en wachtwoorden kwijt. Tot daar..het meeste is opgelost. Maar ik kan niet meer inloggen bij Scarlet webmail ondanks dat mijn gebruikersnaam en wachtwoord juist zijn. Hel lukt wel als ik via Microsoft Edge probeer of als ze het bij Scarlet zelf proberen. Hoe kan ik dit oplossen?

Similar to this https://support.mozilla.org/en-US/questions/1440015. However, I installed Firefox this way https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions

Issue happens in both MX Linux and Linux Mint (Firefox 129.0, 64 bit)

trying to log in to Barclays Bank and keep getting a pop up message loginappcontainer.do 0 bytes I have never seen it before and it is suspicious, please help. can not screen shot it either.?

Hi, I can get the bank website page but it won't let me log in. I have tried all the usual emptying cookies etc. and refreshing Firefox and running Microsoft troubleshooter. This is with Firefox on Windows 11. But I have tried it with Firefox on my Linux computer (Ubuntu) and it doesn't work on that either. Both say the container.do file is empty. Thanks

Hello, whenever I try to type into a text box the "manage passwords box" appears, which is fine with me, but with this website...there is a drop down menu, which then makes the password box completely cover it, and I've been trying to find a work around, but nothing work, I want to save my passwords, the feature is great, the password box is fine with me in other websites, is there like a button to press to remove the password autofill box when I don't need it, or simply just remove the autofill suggestions, because the fact it keeps covering the drop down menu is becoming annoying.

Hi,

It's been a while since this problem first occurred but I am now very sure that this is about Firefox and not about graphics driver. This happens both when the hardware acceleration is turned on and turned off.

When I open a website that has mainly images or videos, the browser goes blitz (Reddit, Twitch, etc.). Screen splits to multiple views, it starts flickering and continues until I switch to another tab or quit Firefox. For flickering to stop, I need to restart the computer. I can also send a video if you can communicate a proper way of sharing. (Drive link, youtube, etc.)

Is there any way I can ensure Firefox does not break things on my computer?

Thanks

I need to connect to my employers Citrix portal tot start a Citrix session for my daily job. The problem is that when try to login using my credentials nothing happens except for the loading icon of Firefox that keeps "spinning" (see image).

When I do the same in another browser, like Chromium for example, everything works fine.

I already tried the following steps:

- Installing an older version of the Citrix Workspace app - Reinstalling Firefox - Disabling the blocking extensions

I am using the following versions of components:

OS: Linux Mint Vanessa 21 Citrix Workspace app: 24.5.0.76 Firefox: 129.0

Other colleagues report the same issues when using Firefox whether in Windows of Linux.

Any help would be much appreciated?

bold text since the last update I have been getting a whole bunch of notices that I must "dismiss" when I start Firefox.

    How can I stop them from ?
