Does nothing Rated 1 out of 5 stars
Does nothing and after installing it I wasn't able to open about:adddons from the firefox menu.
Someone check out the code to see if it's not malicious.
I've tried to reproduce your bug but I couldn't. If you see through your comment, you misspelled addons, as opening about:addons, it opens up.
Also, new features are coming! Here you have the source code of the extension: https://github.com/amg1893/antc
