Does nothing. Just shows sometimes "fxtranslation-notification" on the yellow ribbon and thats all.

I think the problem is Firefox ESR last version. 4 star for when my ESR version is updated or this plugin is updated.

«There are two more planned releases of Firefox 91 ESR and then it will go out of support on September 20, 2022. Users will then be automatically upgraded to the Firefox 102 ESR.»
