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!

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?

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.

I cannot acccess firefox/mozilla support or vpn downloads on one of my devices which I am trying to download the vpn. I am logged into my mozilla account on the device but either bing or mozilla may be preventing me

Any ideas?

Hello,

So, I tried to download a video from my YouTube Premium Account. According to the youtube webpage, that video was downloaded to my iMac. My FF 124.0.1 settings are set up to download to the Desktop. I am running Mac OS Sonoma 14.4.1

Yet the file is not there. I tried searching on the Support page for FF. Lots of articles but no real help. Tons of info about how to tweak the download but Nothing about Where that download ended up. I did give Permission in Settings for youtube.com to download to my iMac, but again, I can't find the file. In the Storage section, it shows 37.5 MB, so it should be on my iMac, right?

How is it possible for youtube.com to show that I downloaded the file but I can't find it?

I am totally at a loss. Never had anything like this happen before. Prior downloads have Always shown up on the Desktop.

Any thoughts? Thanks for your time.
