Firefox Support Forum

Hello Ladies and Gentlemen!

Please read my post completely before answering! Thank you!

I'm using

• Firefox DevEd (manually installed) as my primary driver and
• the standard Firefox (installed from the package manager) for leisure/hobby related browsing

each with its own Mozilla account and profile, on Manjaro KDE. Sadly, either Firefox sees all the profiles. They have usually different versions. If I mistakenly start one of the Foxes in the other Fox's profile, the newer version of Firefox (usually Firefox DevEd) autostarts migrating that profile. Which it renders the profile "corrupted" for its intended Firefox.

I'd like to have Firefox DevEd unable to see profiles (or anything else) intended for the standard Firefox and vice versa. Or at least unable to botch profiles. I do not want to disable migration or use no. Given that Firefox configuration location is hard-coded, I'm not having high hopes for my wish.

I'm wondering if there is a way to keep two Firefox installations completely isolated, other than running them in containers.

Thank you for your time!

When ever I go into about:profiles, I want to open up one of the root directories, but the button leads to the windows file instead. How do I open the root directory?

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?

on most current macbook, when opening downloaded PDF, it does not open in my selected PDF preference. i have it set for my preferred PDF reader, yet it opens with a completely different one. i have checked all settings i can think of bot on the mac and in firefox, and am flummoxed. all i am finding are windows articles with help, and i checked those too but still nadda. anyone else have any suggestions?

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. Nothing works. 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 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 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
