Excellent!!

This extension does not work with tumblr at all. At first it just denied me the ability to see the post screen when I went to make a post. Then it began to do the same thing to reblogs. At this point, it actively goes to a black screen after approximately 1-2 seconds of seeing any page. I turn this single extension off, presto, everything works again. Turn it back on, boom, all black screens again. Since I use tumblr all the time, this means I cannot use this extension (that I dearly want to use!). Please please fix it so I can use tumblr again. Thanks!

Now youtube is not playing because the ads are blocked, I would like to add an exception for the domain of youtube (by decision, I mean, an option to add domains)

Impressions after about a week of use.

Individual pages seem to load faster, but the behavior of the browser itself before and after loading seems to deteriorate (especially when multiple pages are opened at the same time).
Also, some sites don't respond to reCAPTCHA authentication, which may have been blocked.

I think the ability to detect trackers and block malware domains is high, scam sites (phishing?) aren't counted yet, so I'll leave them out of the current reference.

I feel safer with this extension. I also have paid subscriptions with the Malwarebytes firm on every computer I have ever owned for many years now.

Now I can trully use Firefox as my main browser, I always use malware guard.

I love this extension. What I wish is that it could be compatible with Firefox Android and that would be the best.
