Firefox 70.0.1. White page instead of list installed extensions

I like this extension I use it , it's useful but since the last update of firefox to 70.0 (linux fedora) it's like the extension isn't installed but it is !!?? I always must install it and cannot use the site gnome shell extension to set my extensions installed.

not working STUPIDLY in FIREFOX ... I say because there is no reason ... chrome-gome-shell is installed!!!!

extensão corrupta no firefox e no gnome

Installation aborted because the add-on appears to be corrupt.

the best

i installed this on chrome too and making error timeout sync when launch two browser together. some extension uninstalled without confirmation. i uninstall one of this and everything back normal.

Very Good

very very gooddd

Tiene un buen mantenimiento, mejor que las extensiones que gestiona y, por cierto, con ella he podido desinstalar las que no funcionaban por error(que es lo que marca) o falta de puesta al dia.
Es de reconocer que Firefox va tan deprisa en mejoras que los constructores de extensiones están con la lengua afuera, y el zorro, corre que corre...
