Firefox Community Forum

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?

Hi... Funny behavior with Firefox after connecting an external screen. First the technical specs: Macbook Air 13" 2017, Os 10.14.5 Mojave. Firefox 115.25.0esr.

So.. I connect an external screen 800 x 480 pix. Then I go to the screen settings to adjust taht little screen. Now everything looks very big on the computer, so I adjust the computer screen in the settings. The desctopp looks normal again, but not Firefox. All open windows have now been squeezed up in the upper left corner and only filling a 4th of the sceen... strange. Apple support couldn't help. Of course I can drag out this windows again manually, this is annoying. Safari is not behaving this way... Somebody tell something.

Thanks in advance. Jesper
