Since end 2021, use too much cpu/ram... making Firefox very slow and the app sometime unusable (at best, can download 1 video at same time, during this time, it not responding).

Uninstall/reinstall addon and native app is not better.
Wipe out an reset work, but only for some days.
Must reset every 2-3 days for have not too much problem.
It's like if all videos detected are never deleted of the memory of the addon, and continu to use ressources.

PS: Sorry for bad english level.
