Hi Asyn,
Yes Smart Block Master came to Firefox, and I would like it being brought to Brave as well.
Even better to have now developed Script Surrogates extension by No-Script developer Giorgio Maone,
working on this. Re:
https://noscript.net/ and it is even better than Smart Block is.

May also be brought to Firefox as part of the Tor browser.
As this is important to minimize you being tracked out of your socks by such instances.
One of the parties doing this is Amazon via all sorts of governmental institutions world-wide.

-press.vp.consilium.europa.eu
-web-acc.vp.consilium.europa.eu
Why?: They will use Amazon Cloud because of it being more efficient.
To better collaborate.
To have easier restore after a potential (cyber-)disaster.
Access to this cloud from everywhere.
One expects a better security grade than using in-house solutions (government, army).
It is a way to reduce costs.
But not everybody is happy with it.

pushing Shift + Esc keys (Browser Task Manager pops up).
Some extensions can really "lame" the memory workings of your browser and make it slow or not to respond.
