    This could be so freaking good. But ... it can be a real pain in the ass! Why? Because sometimes just having uMatrix enabled in the Extensions page of Firefox will break some websites even though uMatrix is set to "Disabled for this scope."

    This occurs mostly on login pages, and one has to go to the extension page and disable uMatrix to login to a site. This is across both Linux and Windows.

    If there was a way to COMPLETELY disable uMatix from the toolbar... well that would be great.

    The idea is that you should configure the proper ruleset once for the login then you will be set forever. You can create rules in the global scope for things that will often need whitelisting. The top-left cell is the scope selector, from where you can access the global scope.

    In any case, you can disable globally by selecting the global scope and toggle off matrix filtering, not recommended though, best is to create the needed rules so you do not have to ever disable globally.

    If you submitted your specific issue in the forum I could probably guide you on how to solve your specific issue: https://discourse.mozilla.org/t/support-umatrix/5131

    Great replacement for NoScript, thumbs up!

    I really like that you can block everything within one add on. I am still learning how to use it. Two things would be great to add:
    1. I would like to be able to import my old NoScript whitelist.
    2. NoScript had a feature that you could middle-click on a domain in the dropdown list and you could customize to go to another website:
    I had it so I could quickly check that domain on Norton, like this:
    https://safeweb.norton.com/report/show?url=someSite.com
    It would put "someSite.com" (whatever you middle-clicked on) on the path
    so I could easily know whether to allow that javascript for someSite.com, etc.

    Thanks Mozilla for breaking NoScript. Wouldn't have found uMatrix without it. With NoScript, I essentially had to reload pages to Chrome to get 'em to work. Now I can SEE what exactly is going on and give permissions as I need to.

    I'm using block all / exceptions. https://github.com/gorhill/httpswitchboard/wiki/How-to-use-HTTP-Switchboard:-Two-opposing-views is definitely required reading.

    Addon poderoso que bloqueia solicitações de conexões indesejadas, conforme o próprio desenvolvedor, é para usuários avançados, mas nada impede que você se adapte aos poucos e aprenda muito do que acontece "por trás das cenas". Hoje, para mim, é indispensável e insubstituível. Eu poderia ficar sem qualquer outra extensão para privacidade, uMatrix supre todas as necessidades que tenho. Ainda estou aprendendo. Perfeito !

    I've been using ad-hoc blocking methods in different addons for some time. uMatrix combines them all very neatly and conveniently. (And it's now on Android too!)
