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.

Even though i have 56.0.2 installed it's still telling me that i'm using Firefox 50.0 and I need at least version 56.0a1, hence I can't install this addon.

This is a must-have extension enabling granular controls on what gets into your browser. It requires more interaction than uBlock Origin but the learning curve isn't steep at all.

The add-on is amazing! but there is a issue that I can't solve, the uMatrix is blocking the videos from hotmart.com (these videos are from vimeo), when I access my course, instead of viewing my course video I see "Sorry Because of its privacy settings, this video cannot be played here."

I allowed everything on this site in the uMatrix, changed everythinig to green, but no success too, I disabled the uMatrix for this site too, nothing changed.

If I go in Firefox Extensions and disable the uMatrix and reload the page the video loads with no problem, please when you have the time, can you take a look into this issue?

I wish you and all your familly, health, success and God bless everyone, have a very happy new year!

Please, sorry for my terrible english grammar.
