Installed on Firefox Release, it works. Nice.

i am hoping you guys will do an update so that its stable and also its more than a year since it was updated. Right now its okay.

it's not working on my side, using zen browser. clicking extension didnt do anything

Contrary to other comments, seems to work fine on my end. (FF 132)
I would just suggest the following (even for the other broswers): Please see "TabBliss" extension. If you could incorporate a Clock and weather would be top notch! And off course allow me to choose other search providers.
Ty for comming finally to FF!

Unfortunately, it literally does not work.
