With some settings adjustments (e.g. raising the discard delay to more like an hour than just a few minutes) this module works just great. Using it I managed to tame Firefox' memory consumption enough to make it a stable browser again.

Amazing! It works very well

This is great so far! I wish I could visit a tab without it "un-discarding" itself though. I can do this with a Chrome extension and it's nice when you're trying to find a tab. This extension makes me need to "re-discard" for each wrong tab I searched in.

I categorize this add-on as *essential*, at least for people who use more than a handful of tabs, and/or who don't like wasted RAM. **Ever since installing this, it's as though I installed another 2 GB of RAM. ** It should be built in to Firefox. I wrote angry letters to Firefox about their reckless waste of RAM, and even suggested they free up memory exactly as this add-on does. Firefox is nasty -- it will keep on using RAM till there's 98% memory in use and the whole machine grinds to a halt. I was on the verge of abandoning Firefox over this. No installation of FF is complete without this functionality.

This add-on makes my 7-year-old laptop not hang anymore. Now I can wait for the Ryzen 3000 price drop after the initial launch. Thanks bro

Only discards some tabs.

The toolbar icon also appears blank on first click and only refreshes by mouse-over.

It's good. Works almost like The Great Suspender for Chrom(e/ium).

Amazing add-on! Lots of options to customize it to your liking as well.

Literally saved my laptop. Now I can continue hoarding tabs like I usually do without the laptop slowing down to the point where it would take forever to do anything :D

I have the same issue with my Bookmark Bar's FAV-Icons. Already three of them changed to the Auto Tab Discard Suspended status icons with the dot. How do I get the old FAV-Icons back and when will this issue going to be fixed? Until then I need to disable the Addon.

Many of my Bookmarks have the discarded favicon permanently. I have tried removing the Bookmarks, and re-adding them, but it continues to display the faded favicons with the dot. I have tried clearing cache and even uninstalling this extension. How do I fix it? Edit: I have had to disable this extension for now before it screws all my favicons up. And Mozilla has this listed as a "Featured Extension". I am now using Dormancy.

Not bad, but far to be as great as was tab suspender, from the same author. Clicking a discarded tab will auto undiscard it, which is a major drawback compared to tab suspender which had an option to prevent that. No more toolbar icon to get the suspend menu options. And more annoying : discarding a tab will get you switched to another tab, but without any options to control this behavior. On the pro side : from what I notice, this extension is more effective than tab suspender in terms of perfs and memory reduction usage.
