Hello,
(This especially meant for Linux Ubuntu/Mint.)
There are a couple of about:config settings that
I would prefer to see in the Settings section so I wouldn't have to set the settings each time with about:config.
Settings that I do on each pc/lt I use firefox on, because they add to my browsing experience.
Settings that don't get 'synchronised'.
A few:
1) Don't close browser on closing last tab
browser.tabs.closeWindowWithLastTab = false
2) Change width of scrollbar
A too narrow scrollbar can become 'annoying', especially on smaller laptops when using mousepad.
Similar settings I do for my system don't get integrated in the firefox browser.
I like these plural settings that give a clean straight rectangular scrollable scrollbar:
widget.gtk.overlay-scrollbars.enabled = false
widget.non-native-theme.gtk.scrollbar.thumb-size = 1
widget.non-native-theme.scrollbar.style = 4
widget.non-native-theme.scrollbar.size.override = 16
As said, to be repeated on each pc.
3) Don't repeat previous tabs when relaunching the browser
This is a tough one.
Whatever I do, it doesn't seem to help.
Neither when history gets wiped after having closed the browser.
Neither if I have deselected 'open previous windows and tabs'.
Furthermore no complaints 😜
