Add memory usage to tabs when you hover over the tab

[Paulywog72]

Add a memory usage indication to each tab like Chrome/Edge does when you hover over the tab. It would also be nice if a small picture of the website appeared. Indicating if the tab is asleep or not would be cool, too. That's my 2 cents. Thank you for reading.

Display RAM taken by each tab when hovering

Hello again!

Just like in ms edge, the RAM currently being taken up by a tab should be displayed below the tab preview while hovering over it in Firefox desktop. It's helpful for users who are concerned about the performance and power consumption of their devices, especially low-end pc/laptop users.

Thank you!
