On linux, in the past, firefox kept all its data in home/{user}/.mozilla. This was changed at some pont to spread the data out into /home/{user}/.config, /home/{user}/.cache and maybe another place but when the change was made existing data was not moved and remained in /home/{user}/.mozilla. For my purposes I prefer to see the data in the old location. I make heave use of profiles and I store them on an encrypted partition and I have firejail setup to give access to the old location. Whart does Firefox look at to determine whether to look in the new locations or the old location? What is the new location of profile.ini?

As soon as I signed into the browser to sync my account, this issue began. I have deleted profile locks, started new profiles, opened in troubleshooting mode, fully reinstalled, and the issue continued (even before signing back in). I am out of troubleshooting steps and would like to avoid blowing my VM away if at all possible. Someone please help!

I want to have a specific page open when I use the alt+home shortcut (or my keyboard's "home" media key). I know I can do this via the Home Page dropdowns, but that affects new pages and/or tabs. I want those to open blank pages, and only the keyboard shortcut to take me to my desired "home" page. Is this possible?

I am on Pop OS. I ran some update and restarted and all of my tabs are gone and Firefox is not showing any history of them. I was under the impression that if I had an account it would keep track of the history but there is nothing there. How does this happen and why? Also how can I get my tabs back I am one of those people that has like 50 tabs open So I can run several things at once I never had this issue with goggle but for some reason it happens often with Firefox what gives?

Dear Sir/Madam,

Sync feature is not working at all, I signed my account on different PCs to have my history synced across all devices but it is like for nothing, every time I log my account into a new PC to have the search history of the last device nothing gets synced, I wait like for an eternity and nothing there, restart and nothing works.

Good evening,

I am using Linux Mint (version 22.3 Cinnamon) as my OS and Firefox (version 157.0.1) as my browser—both 64-bit.

For some time now, I haven't been able to use the map on www.naviki.org; when the page loads, the map appears briefly but then immediately becomes invisible.

I suspect this has something to do with my Firefox settings. I’ve tried everything I can think of—enabling third-party cookies (for Google and OpenStreetMap maps), toggling tracking protection on and off, removing all browser extensions and add-ons, and verifying that WebGL and WebGL2 are both set to "true"—but nothing works. The maps remain invisible.

Does anyone have any idea what might be causing this? I'm at a loss...

Thanks in advance for any suggestions, Phil

Tested on OpenSuse Tumbleweed both native & flatpak but also on latest live ubuntu image . After some seconds , with healthy buffer , video pauses/starts with new buffer , until it drops to 480p ignoring the manually 4K setting . When setting manually again to 4K , YT throws error . Blocking av1 and switching to vp9 fixes it . Hardware capable of running av1 (amd , rdna3 , rx 7800t) , local videos or using other chromium based browsers work fine .

We often encounter this situation: both at home and at work, I don't want the Firefox password and browsing history on my home computer to be synchronized to the Firefox on my work computer. After all, there are many private passwords and browsing histories involved at home. However, the passwords and browsing histories related to work can be synchronized to my home computer, so that we can continue to view the records from work at home However, I haven't found this function anywhere in Firefox

I have been having random crashes Firefox Snap on Kubuntu 24.04 (and now 26.04). Sometimes Firefox will run stably for over an hour, sometimes it will crash in less then a minute from (re-)launch. I have tried the usual troubleshooting steps of 'run in troubleshoot mode', 'refresh', disable plugins, but the crashing seems to happen even when running in troubleshoot mode. I also have not been able to figure out any kind of event or user-action that triggers the crash; it might happen while browsing, it might happen while I am not even at my computer. At first I thought 'the Devs will handle this', but it has been some 6 months so I think my case is not very common/pressing to the community. I'd like to take a more proactive approach in solving the problem. I am still a novice at software fixing, so I might have skipped or missed a very basic step in the '10 things to try to fix Firefox'.

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!
