>>1675965Sandboxing and individual tab processes are coming in one of the next Firefox updates last I heard. See:
https://wiki.mozilla.org/ElectrolysisAs for the task manager, it doesn't have one since the tabs are not separated yet. You can always check about:memory, pic related.
>Does Chromium still allow you to use Chrome's extensionsYup. Firefox is my main browser but I still use Chromium from time to time to test web pages and all my extensions work.
One thing I miss on Chrom* is the ability to control tabs, Google removed/disabled all the extensions that did as far as I know which prompted me to migrate to Firefox definitively and never return again. It's really painful when you can't double-click to close a simple tab.
Firefox is fucking amazing, you can customize pretty much everything. Rarely have problems that I can't fix very quickly and for people calling it slow, it's definitely PEBKAC because I open a shit ton of Pixiv/Gelbooru tabs on a daily basis and it runs perfectly. Only thing I want now is for everyone to get rid of Flash already.
