Flat out doesn't work. As far as I can tell, it does literally nothing. Probably just sells your data to China or something. Right click still doesn't bring up any context menu when I click on the websites that have it blocked. Wish I could give zero stars.

does not work on the site I tried using it on

fails in spotify

Great, works as expected.

It works perfectly, but it doesn't seem to work on iframes, even if you enable permissions on the source domain.

Took 10 seconds and I was able to copy blocked text - thank you!

Doesn't work for mobile

Perfect!

Works great!

By one side, it works as it promises but by other side, It's able to access browser tabs
and access your data for all websites, such as passwords, which these are some kinds of delicate data. I didn't like this last fact of accessing to this delicated data.

Has slowly stopped working on some sites.

The developer of this extension has resigned. Even if it looks like it, this was not an update on April 25, 2024. The proof is visible to everyone, you just have to click on Show all versions. Version 1.3.9 is the final version of this extension and there will be no further updates. As an honest developer, you should be honest enough to say so in the description of this extension. The extension works fine, but for how much longer? After all, there are continuous updates for the Firefox browser. The single star refers to the behavior of the developer and not to the extension itself.
