Good results, but very poor performance for few past weeks. I had to disable it. Almost suspected Firefox for poor performance.

Wappalyzer kept Firefox's shared extension process busy, so each tab switch waited an extra 0.5–0.8 s before the request was even sent, roughly doubling the load time from ~0.9 s to ~1.3–2.2 s.

Firefox 138.0.1 (64-bit) - Linux Flatpak. The extension doesn't work - "Installation aborted because the add-on appears to be corrupt"

Ni siquiera me deja descargarla, me dice que esta dañada.

Useful for curious people, but terrible performances. It degrades network performances too much.

it slowing down firefox. youtube opens after 10+ seconds... I Disabled it until it will be fixed.

It does not work most of the time. Use BuiltWith instead.

new update fails to show technologies when it detects them indicated by the icon's badge.

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
