I suspect this extension is what's been slowing down Firefox for me and using a lot of my PC's memory to the point of severe lag - it's my only recent add-on and disabling it seems to have helped so far (fingers crossed). Good idea but the slow-down is very significant after a while for me at least.

Good extension, but needs better defaults. E.g. "Do not discard a tab when it is pinned" should be ON by default.

Saw a noticeable drop in the amount of memory my PC was using by about 20% after installing this add-on.

Usually pretty good, but for the past several months now I've been having an issue where sometimes, if I click on a tab that was discarded to open it, instead of loading the actual page it was on it instead just becomes an about:blank page. It doesn't happen too often, but often enough to be annoying and make me have to be more cautious than I'd like to have to be.

Tabs with videos being played through the pop-up window get discarded and this even after I have white-listed the domain!

In the latest 0.6.3.2 version of this plugin, the tabs that have reached the hibernation time cannot be automatically hibernated, I returned to the 0.5 version and it was fine. I am using Firefox Developer Edition 106.0 Beta 6 (20220929195234)

Really appreciate this add-on BUT somewhat buggy add-on... Discarded tab often does not stay discarded.

And if use the "Open a temporary blank page when all tabs in an inactive window are discarded (to be able to discard the active tab on this window)", the discarded tabs often revert back to loaded tabs after a while (within about 20-30 mins in my experience), especially when you use the Discard All Tabs or are discarding the last loaded tab in a window. UGH!

[Edit Jan 25, 2023 - Will this ever get fixed???]

Also, why not use the technique The Great Suspender used (only available or
Chrome)? Instead of a new tab to suspend the last one, it was able to suspend in place.... much more elegant and does not create new tabs.

[EDIT: Jan 28, 2023 - Meanwhile, I just figured out a workaround to stop the discarded tabs from re-loading under the above use-case... When discarding the last tab loaded, Auto Tab Discard opens a "blank" tab page to accomplish this. But AFTER such a discarded tab reloads, that tab/page automatically closes again and the discarded tab reloads. SO AFTER that tab reloads (and the blank tab is closed), simply press COMMAND-SHIFT-T. This will bring back the blank page and discard the last tab again. BUT THIS TIME the discarded tab WILL discarded.

This might give a clue on how to fix this?

OK
