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.

Highly recommended !

Perfect bei richtiger Einstellung

Спасибо, Рэймонд Хилл!

Much better than NoScript, Does not break any site if you use a list.

A great addition to Ublock Origin if you are a power user who is concerned about your privacy and would like fine grained control over your web browser.

It takes some time to get used to it but its worth in the long run as things get easier after a few days of getting used to use the global & site specific scopes.

Этакая лайтовая замена связки noscript+блокировщика рекламмы, после обновления лисы до квантума, и кривизны нового носкрипта, самое оно.

Cant live without this addon, absolutely fantastic.

uMatrix is an excellent, effective alternative to the now completely useless noscript.

Yet another NoScript convert.

I'm glad FF Quantum broke NoScript and the new NoScript is such garbage, as it forced me to find uMatrix. With the pre-Quantum NoScript, it often devolved to "Temporarily allow all this page" until the page worked. Who knows what I was enabling?

The uMatrix interface seems intimidating at first, but after about 10 minutes I had it grokked. The granularity is great.

I do find that uMatrix behaves differently in FF vs Chrome, and I sometimes still have to resort to Chrome to get a page to display correctly. E.g. I use MicroCenter's web site a lot, and the reviews on there seem to come from bazaarvoice.com. uMatrix in FF shows only one element from bazaarvoice that can be enabled or disabled, while in Chrome it shows 20+. I can only get the reviews to display in Chrome.

Still, it's "vurry nize" and has allowed me to remain with FF (for the most part).

EDIT, following the dev's quick response:

Nothing to do with uMatrix, Privacy Badger was blocking bazaarvoice.com cookies. Once I allowed that, uMatrix in FF and Chrome were all nice and matchy. Thanks for the response.

I wouldn’t' recommend for the the casual user as it can be tedious unblocking scripts etc to get a site to work as expected.
However on the other hand if you're serious about cutting out the chuff that sites load and speeding up your web experience - or wanting a tool to block tracking scripts with granular control - this is what you need.
Excellent work.

Actually, this is the beat and very clead blocking tool.

I love it, but... Why needed for the new version to acces my downloads and others?

I used FF for years, then due to the constant changes lately, I switched to Chrome, and now, after FF 57 was released, I was eager to test FF again to see if it's worth to actually come back. It's in Chrome that I first came into contact with uMatrix, looking for an extension similar to NoScript. Seeing that there are many users here who switched from NoScript as well, I thought to re-post what I posted back on Chrome WebStore, regarding importing a long whitelist from an older version of NoScript - maybe it helps someone:

Below you have 10 easy steps to import NoScript's Whitelist into uMatrix (especially if that list is long - like mine was, since I came to Chrome from Firefox):

1) export NoScript's Whitelist to a text file, from within NoScript (if you didn't do that already)
2) edit that textfile using Notepad++
3) select all with CTRL+A
4) click Search/Replace from the menu and tick Regular Expression
5) type "\n" for "Find what:" textbox and " * allow\n* " for "Replace with:" textbox (without quotes, but including spaces)
6) click Replace All, close the dialog, modify the first and the last line in the list to match how the other lines look, then copy the modified contents of the text file again, using CTRL+A
7) go to My Rules tab within uMatrix's Options (Dashboard)
8) click Edit in the Temporary Rules column
9) paste the text you copied at step 6) at the end of the already existing temporary rules
10) click Save, then Commit in the Temporary Rules column

That's it - now you have the whitelist from NoScript into your uMatrix extension. You can then make any further modification to the settings in that list on an individual basis, which is much easier than having to rebuild that list from scratch all over again...

RESPONSE TO THE DEVELOPER:

I wasn't aware that you can directly import those rules when I first wrote this review back on Chrome (27.07.2017), and I didn't know whether you provided the functionality right from the start or it was added afterwards, so I assumed that you can't directly import those rules from NoScript - hence my reviews.

On the conversion type, those are just my preferences, especially given the way NoScript interprets them (i.e. general over specificity for a domain), maybe others prefer them to be a little more restrictive - that's why I said that you can make further adjustments afterwards, on an individual basis. Personally, I need frames to be allowed too on most of the whitelisted domains, as they provide functionality I sometimes need (think streamed media, for example), thus, from my POV, there wouldn't be much difference between a broader whitelist rule and allowing images+css+script+frame (it's allow all vs allow almost all). Bottom line, it might be better for regular users the way you designed it, since it's preferable to be more protected over allowing all and make some mistakes. Me, I know what I'm doing, so I can safely go with all or nothing style.

Simply great add-on. I jumped Noscript's bandwagon since everything I used to know on it have changed, even the functionality and I am really sad to see that (looking at you mozilla)

Much appreciated Raymond!!

My wish list for this addon:
*Clear click and XSS protection
