Hi Alexius, that is often possible. There are some cases where Firefox and Chrome differ and features/functions in one are missing from the other.

More info: https://extensionworkshop.com/documentation/develop/porting-a-google-chrome-extension/

Are you the author of the Chrome extension, or have you been in touch with the author about bringing it over to Firefox?

Hi, No, I am just a Firefox user, I have a few extension on chrome that I have not been able to find counterparts on FF, when I find them, I won't be needing chrome at all.

Thanx, I'll keep looking.

Maybe this article can help: https://hacks.mozilla.org/2015/10/porting-chrome-extensions-to-firefox-with-webextensions/

If you have trouble getting suggestions for replacement extensions, another place to ask is:
