multi-account-containers VS uMatrix

It is an extension for Firefox, but one created by Mozilla. It's official in that sense, but it does seem a little strange it's not included by default.

https://addons.mozilla.org/firefox/addon/multi-account-conta...

the opposite is true, too, since "Clear History" in Chrome Profiles behaves correctly and (AFAIK) is scoped just to that Profile unlike our container friend: https://github.com/mozilla/multi-account-containers/issues/3...

I still use them because combined with https://addons.mozilla.org/en-US/firefox/addon/open-url-in-c... ( https://github.com/honsiorovskyi/open-url-in-container ) is a game changer for my workflow but it does make me sad that issue has been open for so long

I have about 35 tabs open, some are work tabs, some are personal tabs and others are social tabs. About 1 week ago I started having the problem that while I have the Open Containers completely draining, my CPU is at 100%. While when I close them all my CPU returns to its normal state of use 20% I see that the problem is existing. https://github.com/mozilla/multi-account-containers/issues/572 any help? I have the latest version of Firefox on Windows 10

I've been googling around for a way to recover them and it seems like this is just... a thing hat happens? And it has for years? This is intentional? What the hell?

Firefox Containers - Only if you need to use two accounts from the same website at the same time. You can change groups names and colors. When you need to open another account simultaneously just right-click the tab -> open in new conteiner -> choose one and voilá. It took me time to understand how exactly this worked but I use a lot now. Ohh and never ever never set "Aways open this tab/site in this container" this got me nuts these days. Is hard to revert if you don't really need a certain website aways on a certain container.

Can I start Firefox from the (linux mint) terminal opening a website in a particular container (using the Multi-Account Containers extension. see https://github.com/mozilla/multi-account-containers or https://addons.mozilla.org/en-CA/firefox/addon/multi-account-containers/)

Notice that not all functionality is available in brand accounts, e.g., upload your own music to YTM. There might also be some lost functionality when using the brand account at YT, but I don't know them anymore. You should also be aware that it is not easy to switch between different google accounts on PC because they use the same cookie to remember your current account. You can use a different browser for one of YT or YTM, or use add-ons like Firefox Multi-Account Containers. The different apps on android have no problem with this.

My daily machine is currently at 16GiB, the same as ten years ago. My memory usage is down from five or six years ago, which I attribute mainly to uMatrix script-blocking browser plugin.

Can be beacon requests from previous page (happen even now in uBO) or this https://github.com/gorhill/uMatrix/wiki/Lingering-domain-entries-in-the-matrix

okay totally on my side: it was uMatrix :) https://github.com/gorhill/uMatrix/wiki/Per-scope-switches#r...

uMatrix

I need Firefox to a) recognize that some of us simply do not WANT to let any random website run code and b) allow me to assign fine-grained permissions Javascript permissions ala Umatrix (https://github.com/gorhill/uMatrix).

Check your facts.

This vulnerability has been fixed in uMatrix 1.4.2 [0], released few days after the linked news article.

To those familiar with the HTML DOM I recommend uMatrix from the same author as uBlock origin. It makes a good companion to uBlock Origin and provides much finer control.
