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.

Automatic tab discard does not work.

Update request: Ability to whitelist domains to never suspend. I like that I can not suspend pinned tabs, but I only pin a few tabs regularly and forget on others that may need to stay active.

Love this Extension. I like to keep tabs open as I switch between many tasks throughout the day, and keeping the tab open reminds me what I haven't finished yet! The company wont give me more RAM, so this is a great solution to the performance issue having 25 tabs open can cause!

Doesn't work at all. Using the default settings, all tabs are active, using tons of CPU. How does an addon that doesn't do anything get 5-star reviews?

It has a bug where it does not restore the tabs after firefox updates. If you had tried to restore a discarded tab after an update and then attempt to restart firefox without first recovering the tab, it will not recover the tab after the restart

Doesn't work. The setup for delay doesn't work. The setup for which tab stay online doesn't work. Always suspend all tabs after 1 min. I set 10 or 100 min, doesn't work... Useless..

how i can enable favicons, with this small image much easy to navigate tabs, if i cant do this, add this in new version please :)

This is a must-have for Firefox.

Very useful tool! Recommend to anyone that knows how to open links in new tabs.
Only 2 problems I have: no hotkeys to discard current tab / all other tabs, and doesn't save video progress on youtube. Would be great to have youtube tab reload with a timestamp.

Simple, effective, reliable. Does one thing well, just like tigers like it.

Doesn't work at Waterfox https://www.waterfoxproject.org/
This browser like Firefox 56. Maybe there is a version of the add-on suitable for this browser? What happens in the current extension - The add-on is installed, I can change the settings, but in work, when you try to freeze all the tabs, nothing happens.
Other addons from Firefox (until 54 version) working perfect.
