Firefox Support Forum

I've copied the root profile folder from my old machine, created a new profile running Nightly, put the contents of old profile into just created one, and it just worked. Doing the exact same steps with Dev version doesn't work - app refuses to launch after picking imported profile as default one. Could it be because Dev has a lower app version?

I am not sure when exactly problem started but for few months I have problem with automatic update of firefox. It properly detects update and downloads it but when I click to restart browser and apply update (this should close browser and display update install bar) nothing happens - browser simply closes. When I launch it again and go into "about firefox" again I see spinning circle next to "installing update". Of course this update never installs. When I close it for 2nd time and go into "about firefox" it goes back to "update ready to install, click to restart" - and again, when I click it browser simply closes without restarting and installing update. I tried removing my profile, using safe mode, disabling antivirus. Issue seems to be related to firefox itself. I also tried removing mozilla maintenance service but it did not help. Does anyone have any idea what could be causing this? For now only way for me to update firefox is manually download full installer from website and then it installs latest version without any problems - until next month comes and I have to update it again.

I cannot get firefox to update. It is set up for automatic updates but they don't happen. Even if I try manual installation of updates it says the update fails. I ran it in troubleshooting mode and the problem still exists. I restarted my computer and the problem still exists. I am using a mac running on Monterey. How can I get it to auto update again? (and even though it says failed to check for or install updates, it looks like I do have the latest version of firefox)

I've followed this tutorial on howto install firefox as deb via apt. After successfull installation the menu font looks really wierd. It looks stretched and the numbers are not displayed correctly.

The left image shows snap package install and the right image deb package.

How do I download language data for translating on a machine that is not connected to the internet?

I already followed the instructions here to download an offline firefox installer: https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

and I downloaded the language packs I want here: https://releases.mozilla.org/pub/firefox/releases/124.0/win64/xpi/

and I followed the instructions here: https://support.mozilla.org/en-US/kb/deploying-firefox-language-packs

But translation still doesn't work. I even manually installed the "*.xpi" packs into the browser. I can see in Firefox's settings that it thinks the packs are installed, and it offers to translate pages it detects are in a different language, but translation fails. I noticed that the language packs are smaller than I would have expected - smaller than 1MB. Is there a way to download the language data that is needed for offline translations?

Thank you!

I need help with everything to do with email so what is your email address or what is your phone number so I can ask my questions ?

I updated firefox and when trying to open it received an "EntryPoint Not Found" error.

The procedure entry point sqlite3_backup_finish could not be located in the dynamic link library C:\Program Files\Mozilla Firefox\xul.dll

Click okay then get the message

"couldn't load XPCOM."

It would appear I need to delete firefox and reinstall, unless a method exists to revert.

If I delete and reinstall how do I retain bookmarks, history and open tabs, etc.? I need to keep my tabs, history and bookmarks.

Hello, 1. How do I bring history back -since mid March - after a windows system reset and laptop clean up recently? I signed on but I cannot find the prior history nor tabs closed. I use Windows 10. 2. Why when I open a new tab, the 'profile or account' icon does not show my picture, so as to indicate that I am signed on? Each time a new tab is opened, Mozzilla does not recognize me!! 3. When I click on the account icon on the second row, instead of taking me to my account, it takes me to settings, Synch. 4. I have selected the dark mode - from customisation - but the first two rows are in light blue-gray color same as the task bar of Windows 10. 5. I tied to use the take a screen shot function to send you a screen shot of the page that appears in dark except the top rows, but when I click the screen shot icon - that I have placed in the second top row - it does not activate-work. 6. From the Menu some info shows in Greek although my selected language is English. Is it possibly due to my location, under the profile, being Greece? should I change it? I am sure I ll come across more issues, as it feels as I am driving a new car since the change and all is annoying Thanks
