Causes my computer to use over 1,000% CPU while Firefox is completely idle.

Honestly one of the best add-ons I've used with FF. It makes using multiple accounts smoothly simple. I had to re-install the browser the other day and didn't even realise it wasn't a built-in feature until I tried to use it and wasn't there haha.

Of course it can always improve, like they did with opening a shortcut from our fav bar in a new container directly, which previously wasn't possible. So I'm quite excited to what more can be improved to make it even better.

Like, My PC has a few programs set to auto start when I boot it, one of them is FF and it has a number of sites set as my home page to load, so I wouldn't mind if I could set my HP to have the option to open with a container tab. So for example I could set the same social media to open with two different accounts at the same time when I run the browser.

very useful

Love this! So much faster than opening incognito windows!
