ALT-SHIFT-LEFT got remapped to 'select tab to the left' out of the blue

more options

ALT-SHIFT-LEFT has been 'select word backwards' for years, at least on macs. And so it was on FF too. Now they suddenly decided to re-map it to 'select left tab'. There was already a key for that - CMD-ALT-LEFT. Which also works for the right, whereas ALT-SHIFT-RIGHT does nothin

Hi, this issue has been linked to the Tree Style Tabs extension. Not sure whether there was a coincidence of updates or if it interacts with Firefox 127 in an unexpected way.

Phew, emergency over 😆 - you are totally right @jscher2000 and thanks for that

I almost ditched FF because of this, the solution is discussed in this github issue https://github.com/piroor/treestyletab/issues/3575
