Can't install the extension, getting this error: https://sharex.wad.dk/wappalyzer.png
I used to have the extension for years, but i just removed all extensions and reinstalling those i need.
Can confirm this. Tried to install the extension just a moment ago and also got an error message.

+1. Google Chrome 80.0.3987.122
+1. Google Chrome 80.0.3987.122
So it's the version?
https://github.com/AliasIO/wappalyzer/issues/2949 Problem is in Review process as Developer says. Just keep it locked and lock this thread also.
P.S.: I found that problem too after reinstalling system, before that is was working fine. Thanks Firefox, there plugins works fine.
I got the same error a few minutes ago.

v5.6.9 is still 'pending review'. It's taking a lot longer than normal, I emailed Google asking if they can prioritise it.
For now, you can clone this repository, navigate to 'about:extensions', enable 'Developer mode', click 'Load unpacked' and select the 'src/drivers/webextension` directory.
You can also use the bookmarklet, or Firefox/Edge.
It's working again now, sorry for the wait.
