Not only Apple... see below for a totally different issue.
And you probably installed and re-installed the extension from AMO using that icon in the beta's Extension section of the settings... and that's not going to work because the way the icons are used has changed.
And the AMO version will probably only get updated once the beta becomes an official release. (see edit)
I forgot about this but this has been an issue for a while now when switching from release to beta version... I used to only be able to install the extension from local source in the Developer version, but neither
my original trick nor the one
@r37r05p3C7 pointed me to seem to work anymore in that version. The first method just keeps complaining about a corrupted extension and the second just doesn't do anything anymore.
EDIT: I'm awaiting permission from
WillyJL to upload a signed copy of the extension for Firefox that works with the beta.
As soon as he approves, I'll add it as temporary attachment to this post until F95Checker is released publicly.

Ok, permission is in. Please note that it says Beta in the name, and will have a different ID than the official one... best is to temporarily disable the official one from AMO instead of removing.
and as soon as the public version goes out, this one will be removed and you'll need to redownload from AMO, deleting/removing this one from your browser.
Unzip the extension and drop it on the Extension page. If you have your browser set as system default, double-click probably works too. Can't verify that myself.
