Doesn`t work on Firefox 89.0.1

Now you need a pro account to use it... It doens't work free anymore.
New version (v6.7.7 isn't free, no changes). TicTacToe fails and We can't watch information, I'll delete this addon and install Whatruns which still be free. Thanks for all this time

slow page load

Functionally great add-on, but rated low for poor privacy policy.

new update make background blue

After new update came this horrible blue design. Cant read at all

Slows down the browser and creates a load on the system. When removed, everything is normalized. Tested on 4 computers on Windows systems in Linux

work bad now. cant check the cms and many other. also move back to adress line icon

Very good result but slow down page load. Normally i have 0.75'' without enable this addon. When it is enabled the page load in 1.4''. Please make a choice to run addon ONLY when someone click on the icon and not every time when page load. I have the wappalyzer icon and not the cms icon to display but the result on page load is the same.

Doesn't work. Icons not even showing

doesn't work on my PC, with Windows 10 and Firefox 71.0

Ne fonctionne pas sur firefox developer à jour

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.

This add-on is usually very useful.

But since version 6.12.1 the add-on comes with a memory leak/infinite loop that trashes the performance of the entire browser to the point of making it unusable. Multiple reviews have pointed out the flaw, and even the author acknowledged the issue. But more than two weeks since the buggy version was released, and still no fix yet available.

What is going on?

I can install this addon but the icon isn't show. I can't use this addon on firefox, on google chrome it's O.K.

My version of firefox : 58.0.2 (64 bits) Firefox Quantum

Läuft leider nur unter Google Chrom da meine Version von Firefox die 58.x ist.
Wappalyzer sagt mir aber ich verwende eine alte Version 42.0 und sollte 48.0 nutzen.
