4 MINUTES start up time!
Every time I open Firefox it takes approximately 4 minutes before doing anything. I've a 4 core with 8 gb of RAM, my cpu usage stays at 12-15% and RAM use is 1.2 gb during these 4 minutes. Firefox seems just waiting. It's not freezed, just waiting. I can open as many new tabs I want, type an address and hit ENTER, and FF will show the gray dot moving (like it hasn't reached the network, because then, when it starts to load the page, the dot becomes blue). After FF "wakes up" everything gets normal, I can use it normally. The issue is only after closing and reopening FF. During the 4 minutes sleeping time, the network works, I can ping and use other browsers. I'm on linux mint 19.3, FF is 75 (but I had the same problem with former versions too). I once did a FF reset, and it was ok for the first boot or two. But then I linked my FF sync account (I use it for: bookmarks, tabs, passwords, addons, preferences, not history) and I got back to my problem. As for the addons I only have "multi account containers" and "video download helper" (just 2!). Additionally I enabled the build-in anti tracking feature. I'm sure something is working wrong.. Can you help me??

Hello,
Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
- Click the menu button
, click Help 
and select Restart with Add-ons Disabled.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
- On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
- On Mac: Hold the option key while starting Firefox.
- On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
When you figure out what's causing your issues, please let us know. It might help others with the same problem.
