Firefox Support Forum

How to download the format in the main qa of the is sangu question regarding your to show the subjective other in the same line you can't be in the same direction.

I am running macOS 10.15.7 and Firefox won't upgrade past ESR v. 115 to the "regular" version 127.

Alternately, downloading the Firefox v. 127 installer and running won't update ESR v. 115 nor will it import bookmarks or data from the previous version ESR 115. Firefox v. 127 installs and starts as if I am a new user without any update or import option so that all previous settings, passwords, and data from ESR v. 115 are lost.

Is there a work-around for the upgrade to keep continuity, settings, bookmarks, and data when migrating to v. 127? Thanks!

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

Thanks. jt

I want to create a link in the bookmarks toolbar to easy check and update firefox In chrome I can do that with creating a bookmark to: chrome://settings/help In edge I can do that with creating a bookmark to: edge://settings/help I have search for, but cannot find the equivalent in firefox

I have chosen to not auto-update the browser because it interferes with my work. The precise setting is called "Allow Firefox to" "Check for updates but let you choose to install them" (screenshot attached). However, this setting is not honoured. Every month, the browser auto-updates and forces a browser restart for me to continue working (screenshot attached). For 126->127, there was in fact no notification to update and the update happened automatically in the background with a restart forced upon me. What's the point of having this setting if it's not going to be honoured?

So After today update i lost my session, all the tabs gone. All i can do i going through miles of history. No recent closed windows no session restore. Had it on my phone - managed to get one (no option to send all to device, only one by one) but the moment it synced gone there as well, apart the one i sent to device, of course. 127.0 64bit.

A firefox support article told me to reinstall firefox from snap on ubuntu, without mentioning anything about the profile, settings, and bookmarks. Now everything is gone.

Is there any way to recover my local profile?

I don't think it was synced properly with my other devices

I upgraded from 126.0.1 to 127 today. Upon update, all my windows are gone. The only way I could access them is to revert to an older profile backup and reinstall 126.0.1.

I tried exporting my session with Tab Session Manager in 126.0.1 and reopen them in 127, but that only restores the last tab of each window (oddly). The json clearly lists 3 windows each with multiple tabs. I tried copying the sessionstore-backups folder, but no dice.

Hi folks,

I'd like to obtain some clarity on provenance aspects of Firefox released as a Flatpak.

I see in this article that one of the options is to use flatpak package: https://support.mozilla.org/en-US/kb/install-firefox-linux

Is this article produced / reviewed by mozilla? Is flatpak an officially trusted, backed by mozilla, means of installing firefox on a system?

On flathub one can observe the "Verified" seal which indicates that such package is developed and maintained by original package developers (in case Mozilla). One can also observe in multiple forums here and there that mozilla is the one that builds and maintain this package.

Though a seal is nice, and users opinions are ok, it would be good to have artifacts that would evidence better this relationship. Also, would be good to have this officially stated in mozilla's website, under "Download options and other languages" section, something like "you can also safely install firefox through the flatpak package available on flathub which is developed / maintained / signed by mozilla itself".

Or maybe all of this information is around and i am just not able to link it together.

Thanks

All of a sudden, I can't download any attachments, no matter what file type it is. I've reset Firefox to it's default, restarted, everything suggested. I don't have the first clue as to what this is.

I'm using Ubuntu 24.04 and just reinstalled for unrelated reasons. I'm trying to copy my Firefox profile over from my backup to the new installation.

I used the Ubuntu Snap store to install Firefox and put my old profile in -- this is the one that I was using on my previous Ubuntu 24.04 installation just a couple days ago -- and everything seems fine, but I do see this error message:

[ERROR error_support::handling] suggest-unexpected: Error opening database: Incompatible database version: 18

It gets printed when I type things in the search bar, so it seems related to some sqlite database related to history and autocompletion.

Is there a way to fix this? I'm fine with just deleting it, so long as the other parts of the profile remain.

(This is a strange error, since after all I was using the exact same setup -- Firefox on Ubuntu 24.04, installed via snap -- just a couple days ago, and it was, as far as I know, up-to-date.)
