Firefox should suspend tabs to better performance

[EduardoBernal]

Firefox isn't with useful tool, which is tabs suspender, it saves of much hardware consume and doesn't allow your PC stay slowness and/or your own internet, because tabs can consume internet and recourses in background without you use it, so that's important and should be in all popular browsers including Firefox. I recommend they base on auto tab discard and possibly performance tool (by Microsoft Edge), because auto tab discard extension is really complete and very useful, mainly it saves where you stop on certain time video and performance tool saves much your recourses on your computer and is very efficient:

A "suspend" indicator would be quite nice—for example, via the tab background color or tab text color (you could create two separate settings for this to ensure compatibility with any theme).

@Horus_Sirius Currently the fav-icon gets greyed out when a tab is unloaded. Though having another color option never hurts.

Also not sure if this was mentioned yet.

I would love to see an option that shows the per-tab memory usage. This is currently a native feature on Chrome. As always a way to toggle visibility would be nice.
