Diễn đàn hỗ trợ Firefox

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)
