Excellent. Frees up memory and CPU by unloading the page and its active assets, but keeps the tab in the list. Prevents Firefox from focusing the unloaded tabs well enough but sometimes Firefox does what it does.

I regularly have 50+ tabs open. Since Big Sur, being able to unload tabs makes the fans run quietly.

A great add-on made much better through its Tree Style Tab integration.

great solution while is still not implemented natively

Works great. But this addon appears to cause the wrong tab to be selected after closing tabs. I had to prefer the left tab instead of the right otherwise I need to switch manually to the correct tab all the time.

Crap. Does not support multiple tabs. Not rocket sciene to do so. Only power users would do this, and which power user would unload loads of tabs individually.

Wish it supported unloading multiple selected tabs

Nice addon, but please add Timer for auto unload tabs (except pinned tabs).

I have no idea why it only occurred to me now to look for this feature when my computer is so old and I have 40+ tabs in 6 groups...
This is amazing, thank you for the work and sorry that FF made you redo your work for nothing.

This is a great add-on!
I always have too many tabs opened and recently Firefox (85.0.2 64-bit) ate up more than 60% of my CPU-performance and 90% of the (16GB) RAM. After I have installed this add-on and have used "unload other tabs", Firefox only needs about 3% of my CPU-performance and 25% of the machine's RAM any more.
Thank you very much for your time and effort programming this add-on! I hope that there will be updates for this add-on in the future if necessary.
