2023-12-20	Firefox user 14675327	unfortunately too few setting options or the setting options offered do little to change the behavior
2023-10-10	Kris Houston	Sleep Mode is a good idea, don't get me wrong. I've use this extension for a very long time while on Windows and without any problems until now. A few weeks after switching to Kubuntu 23.04 and then to Fedora 38 later, Firefox began crashing almost immediately. Disabling all extensions and re-enabling them one by one in Safe Mode traced the cause of all Firefox-related crashes back to this Sleep Mode extension. Because of this, I cannot in good conscience recommend the Sleep Mode extension to anyone until this fatal bug has been fixed on Linux!

2022-09-11	urbade	The idea of this extension is fantastic! I have it installed since years (it is an older laptop, where RAM is precious) and can see the immense effect of putting the tabs to sleep. There is still a key point missing to make it consistently powerful: The counter should be applied for each individual tab: When I have e.g. 15 tabs open, 12 may go to sleep, but I am still actively working with 3. But these 3 tabs then have to wake up every time I switch between them - which costs time on machines with little power.

2021-06-23	Aaron	I grabbed this addon when I saw FF constantly eating up bandwidth when I'm not using it. The good is that this addon solved that issue. The bad is that the timer does not reset itself to the user-defined interval, so the timer is a pointless feature. The ugly is that disabling the addon triggers every tab to reload; that simply should not happen. Almost but not quite usable. EDIT: Was looking for a builtin FF setting but instead found Auto Tab Discard. It offers more options and just works.

Truly amazing!!!! my cpu fan is off and I am running a i9 mac and bottom case of the laptop is so cool for the first time I can remember!!! Thank you thank you thank you!!!
