Yeah, it's just a small quality of life thing that I thought I'd share

It probably doesn't need much tweaking to work on other browsers. Will definitely look into it.

Just an update: It's now available as a userscript for other browsers. Tested on Firefox with Tampermonkey.

in my experience, a ton of chrome extensions (at least MV2 ones) work in FF basically out of the box

it's not necessarily true the other way around, though, because there are some weird things that google chooses not to support (e.g. promises, they require that you use callbacks instead)

Chrome extensions also work on other Chromium based browsers e.g. Edge, Brave, Opera, Vivaldi etc.
