foxyproxy fails to install

Hey guys,
i have a reasonably fresh kali box and i have been trying to install foxyproxy but it fails.
I tried downloading the xpi from windows and transferred it to kali box, but it says that addon is corrupted.

I checked for firefox updates on kali box, no updates available.
Firefox can browse the internet just fine.

anybody knows what i can do to install this?

I’ve the same issue since the last Firefox cert expire.

They fixed this in win versions though. Linux versions? what can we do to install addons!?

Update your firefox, happened to me as well, there is also a patch FF addon if you do not want to go to a full update…

I had the same issue and opted to used an older release of foxy proxy.
