Thanks, this is very useful.
Only thing is, the tabs are to narrow for me. I tried to change
.tabbrowser-tab:not([pinned]) {min-width:35px;max-width:35px;}
to
.tabbrowser-tab:not([pinned]) {min-width:35px;max-width:70px;}, but it didn’t seem to work for me. Could you give me any pointers?
Also, the native functionality that starts with wide tabs and shrinks them if they start to be many is cool. Would there be a way to keep this while having several tabs, when the native display starts to use some scrolling? That’s a pity that Mozilla doesn’t offer an option to switch to multilines instead of scrolling.
