Some about:config things maybe better in the Settings section

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 😜
