Firefox Support Forum

I'm using freshly-downloaded Firefox version 102.2 on a brand new laptop (Windows 11 Pro version 21H2), and every single extension is showing a "Installation aborted because the add-on appears to be corrupt" message when I try to install. I have tried checking for updates, quitting and reopening firefox, restarting my computer, refreshing firefox, uninstalling and reinstalling firefox, as well as any and all combinations of those. I've scoured these message boards and nothing is working for me. Please help!

I'm trying to perform the clean reinstall for Firefox on my computer. But, I see the instructions for the uninstall, Delete the Firefox installation folder, which is located in one of these locations, by default:

   Windows: (Note: Check both folders.)
       C:\Program Files\Mozilla Firefox
       C:\Program Files (x86)\Mozilla Firefox 

Being I'm not computer wizard I had trouble finding the location of such folder. But when I accessed my program list in my windows program list I see a program named Mozilla maintenance service. When I click on that I see a format/window to "uninstall C:\Program Files (x86)\Mozilla Maintenance Service\." Is this the program/folder I need to uninstall to complete the proper instructions I need to perform a clean install? If so, when I delete it I then reinstall Firefox once again after the uninstall procedure? Is performing the uninstall procedure going to screw up my Firefox browser and my many bookmarks I have accumulated over the years? Can someone please help and explain? Thank you.

I got an error message when playing a movie that said clear cookies & cache so I did that. The movie played after I did that. Now today I opened a weather link and when I clicked on precipitation it didn't work. I clicked on a One Tab link to youtube and it opened youtube home page, not the specific link with all my history and feed lost. And some youtube videos would not play. I tried to open my Outlook email from one tab, but I just got outlook and had to re-sign in. And then I could not open an email. I had to switch to chrome to open the email. I tried to use trouble shoot safe mode. I was able to play a youtube video, but my extensions were then unavailable in safe mode, so no one tab. I am 75 and not very computer proficient, and I am afraid I will make things worse because I cannot predict the outcome of the steps offered. Mozilla/Firefox updates automatically, so I have the latest version of that and I have macOS Catilina version 10.15.5 Is there anyway to undo this mess? I need help at the most basic possible level. Can the clear cookies & cache be undone? Is my youtube history & feed able to be restored some how? Help please!!!

Hi everyone, I am currently using Firefox "112.0.1 (64-bit)" on Windows 10 "10.0.19045 Build 19045]"

I have problems using almost all Google websites: most of the times they do not load at first attempt, and when they do they do not works properly. As example: Youtube does not load (or the cached version says that there is no internet connection), then after a few attempts it loads but all thumbnails on the home are gray.

On another browser (Edge) all websites works normally.

Using private window has the same problem, I have no extension and no plugin other than OpenH264 Video Codec provided by Cisco Systems, Inc. and Widevine Content Decryption Module provided by Google Inc.. I tried emptying cache and also reinstalling Firefox.

The only fix I found on the web is to disable hardware acceleration from settings. If I disable it and restart the browser, then all websites works normally. Actually I can't see this as fix but as a workaround, since I am using a notebook and I'd like to use my GPU for video decoding and save energy.

Maybe I am missing something? Is there something I can do? Thanks.

Hi,

regarding vulnerability CVE-2023-3600 when I check advisories it says that version below 115.0.2 ESR are affected. Does that mean that only 115.x versions are affected or all versions are affected like 102.x ?

Regards

firefox kept freezing up and slow load... I did a system restore then i uninstalled then reinstalled firefox browser... are my old bookmarks gone forever. firefox installed a new bookmarks folder. are my old bookmarks gone forever? firefox installed a new bookmarks folder

How do I get rid of keybinds or at least change them it's really annoying when I'm working on stuff and i try to close one tab and then i close the entire window by accident by fat fingering shift.

I cannot find an option in the settings to completely turn off translations. I vastly prefer English, Dutch, German, French, Italian, Spanish and Portuguese websites in their original language simply because I can read them and translated versions always have issues. But now firefox (I am on version 119, windows) continues checking (and asking for each language) wether I want something translated. How can I turn translations off completely?

Would be nice if someone from Mozilla could build this into the browser, so users can easily change their Time Zone.

( Timezone Difference: The time zone of your browser is UTC while your request IP location timezone is different. )

Currently have privacy.resistFingerprinting on which is giving website the UTC time zone. How do I change this without disabling the setting.

Can I go into About:Config and add a new timezone?? that the Javascript request will find.
