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
