Wappalyzer has always been one of my 'must-have' add-ons, but recently it became too heavy on resources!
I find my laptop fan spinning too much while doing nothing, and after I opened Firefox' `about:config` I found this addon uses a most of resources.

I use it, Very helpful and easy to use.

Consume mucha memoria y energía después de un tiempo activo.

Tap in the collapse menu, some content will not be displayed

Super helpful tool!

Now with the new version, if I click on the icon, it is slower to load details but the addon is back to normal.

Previous review: Doesn't work anymore. No details about what technologies are used on the website despite being indicated by the icon's badge.

I will change my review if it come back.

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

Edit : version 6.7.7 just fixed this!!
Great extension thank you
previous review: stopped showing technologies on Firefox 89.0.1 for ubuntu, note that it was working very well but latest update made this !! I've been using it for the past 3 years on all my laptops including at school so it pains me to give this 1 star I hope it gets fixed soon and I'll be more than happy to give even 10 stars

Excelente, recomendo!
