Strange. Mine is below as recently up-dated to FF 131.0. I can drag the back, forwards and extensions icons wherever I please, though feel no need to change them.

If the "Tab Overview" is that downward pointing arrow at the right of the open tabs it's now been replaced with a folder which your screenshot shows. It's not on mine as I deliberately removed it.

Yeah that's the thing, i am on 132.0b2, I wanted to see if i was the only one who experienced this since this new UI makes absolutely no sense, also about the folder you mention, it was there when the tab overview was a thing they are different, anyways should i try reinstalling?

Personally I'd stick to the standard channel where 131.0 is the latest and hope that by the time 132 take its place these problems have been fixed — we also need to hope that they aren't deliberate 'improvements.'

Betas will have problems and people finding them is the point of releasing them but they aren't meant for normal use.
