Firefox Community Forum

Hi all, I'm having an odd problem. For some time now, whenever I look at a list of programs on my computer, Firefox shows up twice. In the last week or so, a new problem has cropped up. When I click on a link in Thunderbird, Firefox opens, but it's like I'm in a totally new instance of Firefox. My browsing history doesn't exist, it will not remember that I have already told Firefox to always open Zoom when I click on a Zoom link, and if I'm streaming a radio station, that tab will be in a separate window rather than in a new tab as it was before. What's going on here?

I've 3 Facebook Profile. One Is Default, Second Is Social Media And Third Is Work Profile. All 3 Profiles Settings Are Similar Like Remember History, Remember Cookies, Remember Site Setting Etc. I've Facebook, Twitter, Instagram Login In Social Media Profile. I've Gmail Login In Default Profile Where I Use Google Products. I Dont Have Social Media Accounts Logins In Default Profile But Still In Settings->Privacy & Security->Manage Data. It Shows Facebbook, Instagram, Twitter Cookies And Same Shows In Work Profile. But When I Clear Facebook, Twitter, Instagram Cookies From These Profiles, All Social Accounts Logins Are Automatically Signs out In Social Media Profile But Cookies Shows In Social Media Profile. Another Instance, I've Gmail Login In Default, But Google Cookies Shows In Another Profiles Too. And When I Deletes From Their, Its Logs Me Out Here In Default Profile. So My Question Is, Whats The Point Of Having Facebook Profiles? And Because Of This Reason I've To Set Settings To Remember History. Still, It Logs Me Out From My Accounts. And It Happens Every Single Day. Totally Frustrating, Annoying. And Because Of Frequent Log Out, Login Issue My Google Account Was Blocked By Google. Need Solution On This Issue.

I use scoop to install firefox. then i changed the default profile to the Scoop profile. Then i tried to log in the mozilla account but it keep saying that it cannot continue because cookies or localstore are disabled. Then i checked the about:support page like i said in the titile, many configs are blank. Maybe some problems with the profile i guess. I also opened a issue in Scoop githup repo, they cant reproduce my problem. Where could go wrong? Any help would be appreciate!

And this is the issue i post on github https://github.com/ScoopInstaller/Extras/issues/15770

I have 2 separate firefox profiles that are open at the same time. I made a shortcut to open the second profile as a new window but it still shows up in the original firefox taskbar. How can i make it so the second firefox profile can be clicked to minimize and maximize the window in the taskbar? in the picture im hovering over the original firefox icon and whenever i press the shortcut icon it make a new window with profile 2.

In the past, I would create new profiles in Firefox often on my macOS Macbook pro. I want to merge them all together (merge open tabs and their saved info, cookies, bookmarks, passwords, etc.) into the same profile.

I found this tool: https://github.com/james-cube/firefox-session-merger but I'm not sure if it will do everything I want to do.

Is this possible to do without using Firefox Sync?

Since updating Firefox to 140.0 (I am currently on 140.0.2 on macOS Sequoia 15.5), when I launch a Firefox window using the non-default profile, that window is not able to load any pages. When I try to close that window, it either requires me to "force quit" it, or if I wait long enough, the Firefox crash reporter appears.

When I first create a new profile, it works. However, after closing that window, or restarting Firefox, the non-default profile can't load pages and eventually crashes.

Things I have tried:

• Deleting all profiles and re-creating them.
• Using new-style profiles instead of the ones managed by `about:profiles`.
• Visiting a local address using an IP address to rule out DNS issues.
• Starting with the non-default profile (using the new-style profile switcher)
• Starting the non-default profile in troubleshooting mode (the browser crashes when trying to restart)
• Clearing the startup cache in the non-default profile (the browser crashes when trying to restart)
