Well, the old version didn't use native Discard API, so it still used resources, although low. The latest update uses native Discard API, so it saves the exact same memory as something like Auto Tab Discard or native Firefox discarding.

Thanks for your feedback, and I’m sorry for the trouble. This update was a major overhaul to improve performance and memory use. I know it may have caused disruption, and I’m working to make future updates smoother. Your input is much appreciated. it helps guide improvements.

That's not a bad idea. I'm working on implementing them for next update as long as there isn't any unexpected issues. Edit: Hey, I fixed the biggest limitation you pointed out, feel free to reinstall my addon.
