Doesnt work in either Firefox developer or normal Firefox. No icon appears. I tried deleting and re-installing but this didnt fix the issue.

Hi there. I have used Wappalyzer for a long time. I love this extension. I use it on Chrome, but it's not working on Firefox (Windows 10 Pro - Firefox 72.0.2) neither on Linux (Fedora 31 - Firefox 72.0.2). The problem is that the icon doesn't appear in Toolbard and there's no way to add it. Please Elbert, take a look on this. Thank you.

Revisited:
It's actually working well. My bad was search for its icon in the toolbar, but it appears next to the search/navigation bar, just to the left of the bookmarks star.

See ya.

I use this on Chrome and Firefox on Linux but did not work on this Win10 I just tried.
