firefox dev 60.0 woking very well, thanks!!

Excellent. This was what I've been looking for! Does a great job at selectively blocking unwanted scripts and 3rd parties.

An absolute must have to surf serenely on the internet.
Simple and user friendly for anyone want to take back control of there digital life.
One of the first addon I install on a fresh Firefox, the ultimate combo combined with a good ad-blocker for security, privacy and memory usage.

Excelent add-on. Keep going good work.

Must Have..!

Best add-on ever, takes some time to set-up but offers great control over everything. I also use uBlock Origin mostly because of the cosmetic filtering which isn't possible with uMatrix.

good firefox add-on

good

Perfect if you want to have full control over your browser's queries, no data send to external servers.
Requires customization for most sites, worth it if you are already used to NoScript (I use this one now instead, allowing, by default, only 1st party content without scripts, which I enable manually). Once set up for your main sites not much of a hassle. Sometimes requires some experimenting to find out which content is actually required. Creates awareness.
