Yes... I'll try to make a Firefox version ASAP! (Chrome extensions are compatible with Opera/Edge...)
Awesome, please yes. It would be great to have a Firefox version.
most of the chrome extensions should work easily with firefox. Because chrome=browser in manifest v2 at firefox (I don't think manifest v3 has arrived in firefox)
However what I can tell is making extension in firefox is more fun than chrome in manifest v2.
