Firefox 社群討論區

So I just upgraded my pc and it bricked my windows and to reinstall, I forgot to save the Firefox data before doing so because I thought it wouldn't cause any issue, well, now all my bookmarks etc. are gone and I'm wondering if there is some sort of backup somewhere saved by Mozilla in the cloud.

So every time the browser crashed or a blackout happens and it forced closed (sometimes the browser is closed normally and it still happens) the next time i start the browser it would show the restore session page. Pressing the restore session would just restore the open tabs and not the tab groups. Because of this i would need to go to the file manager, copy the previous.json and change it to replace the sessionstore. it's kinda annoying. is this problem just me or is this a known issue? also how to fix.

Hello Mozilla Team,

I'll directly jump into - 12 years of Bookmarks and history are gone after the last update. No warning or anything. Can you help me restore? That's unbelievable.

My Firefox crashed and one of my windows with a bunch of tabs was lost. I have a bunch of windows open for dedicated sorting of tabs (one for socials, one for videos, etc). Earlier, my Firefox crashed and it attempted to restore my session but did not restore one specific window I had. I looked in the "History > Recently Closed Windows" and it was not there either. This specific window had a bunch of work related things on it and while I can sift through my history and re-open each tab individually and rebuild it that way, that's really frustrating and time consuming. Is my window just lost now?

Firefox completely changed overnight without notice and I have lost all my bookmarks and can't find out how to access TV channels that were easily available previously on my desktop. Trying to make sense of changes but struggling. Nothing that used to work for me is still available. I don't even recognise it. Might have to give up Firefox.

I have this icon on my Firefox logo pinned to my desktop and it has changed the entire look of my FF how can i reset it to what it was and get back all my bookmarks.

Can someone please help me

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

recently bought new desktop and upgraded win10 to win11 in the process (preloaded). I found 'places:sqlite' in win10 firefox and copied it to usb drive. How do I copy it to win11 firefox? i.e. where is the folder containing the sqlite file in win11? will copying the file also place the bookmarks in the win10 firefox locations? Will the layout preferences transfer over (hate to be negative, but I hate the win11 firefox interface that was preloaded on the new win11 machine.) thanks for anyhelp.

I got a pop-up that said I needed to upgrade my Firefox so I clicked on (Firefox ESR-64Bit) and lost my one and only profile in Firefox. HELP I need it back it has all my passwords and bookmarks
