Worked great for a few days, then disappeared from the extensions bar in Firefox. Tried reinstalling, disabling, safe mode, and nothing gets it to appear back on there. Haven't had any issues with the Chrome version though.

This is a wonderfull tool and it's has a high accurancy detection that's why I love it.
In firefox it's located in a very nice location when you install the addon right next to the url bar
I love this.

In fact I did intergrate it online here

Nothing show in firefox dev version69

De add-on installs, I can change settings etc.
But the icon doesn't show on top in the taskbar together with the other add-ons, so I can't use it. I use latest update v68.0 (64-bits).
For now only 1 star!

It doesn't work, when i click on wappalyzer icon it just shows blank page.

Really useful for me as a web designer / tech-support / generalist fixer thanks. Great to get an idea of how different tools are used, without having to 'view source'.

Helpful for discovering website background.

Cool
