Old review:
It breaks certain websites, for example try (with and without module) this : https://www.backmarket.fr/fr-fr/search?q=dell ; many elements of the page disappear when activating the module (menu bars, left panel, sorting menu, etc.)

New review :
Quick bug fix, I upgrade to 5 stars

This addon does what it promises and is very helpful, but it breaks certain websites, particularly the button layouts.

EDIT: I could not find your mail address in the developer profile to send screenshots of the issue. Try the website mydealz.de and look at the top bar buttons.

There are some (a few) websites that will not display, f.e. https://www.farmacotherapeutischkompas.nl
This is a official site of the Dutch government.

The developer told me he/she considers this as spam, and has asked me to remove it.
Well, the app normally works ok, that is why I gave it 2 stars, but there are some websites that will not display, like the one above.
I have corrected the url, it contained a typing error.
I suggest the developer does have a look at the problem, and if it is repaired, I will give it 5 stars !
