Firefox Community Forum

The welcome addition of Tab Groups I just noticed on updating my Firefox, however looking through help and documentation, it's not clear to me if Tab Groups syncrhonise across devices (or at least desktop devices) as like recently added to Chrome. Wished to check if this is case

My password is accepted to get into Firefox but not accepted to sync, I guess it is. It used to do so for years but now will not after the last update. Doing what the threads already suggested does not work in part because my Firefox does not even have the same places to activate what the suggestions offer.

I am a noob with Firefox jumping over from Chrome. I use tabs a lot and it would be helpful if tabs were synced across browsers. I am really enjoying Mozilla and the performance is great. Thanks. Steve

Hello, I was wondering if there is a way that I can only sync certain things from my firefox browser to my firefox developer browser? Everytime I log in to my firefox acount on the developer browser it changes things that I don't want changed. For instance it will change the dark theme from the developer to the regular, and if I turn it off then it also turns off the dark theme on my developer addition, then I have to log out and fix everything on both of them. But it is nice to have my passwords on the developer addition, that is really the only thing I have found so far that I need.

(This is copied nearly directly from a post on r/firefox made a few hours ago—I decided it was best to spread it here for more exposure. The only change was the removal of the add-on names from the title due to character limits; these are Form History Control and Text Area Cache.)

I hope the title explains what I am looking for well. My main computer has had... spooky behavior with its file system recently, and I have been recommended to make a back-up, format my drive, and re-install my operating system (possibly upgrading from Windows 10 to 11 in the process). The biggest hold-up to me doing so is this, as I have no idea how to transfer the extension data between installs, or convert it into a human-readable form. The sheer number of writing drafts in those extensions both make losing them an unacceptable situation and copying the data manually into a document entirely impractical. So, can anyone help me with this? For context, I was on Firefox 138.0 when I stopped using my main computer due to those issues. (Note: It will certainly last long enough to do the Firefox Syncing and other back-up operations, just not for many more weeks or months.)

Hello, I use Firefox on two desktop computers and one mobile device. Firefox is being slow on one desktop, so I want to "refresh" it. The [page] says that extensions and search engines will be removed... but will they be restored by Firefox Sync from the other desktop computer? Or will sync also remove extensions on the other computer? Thanks
