Great add-on, why is this not integrated into Firefox directly? Pretty sure Chrome is good at suspending tabs intelligently, but FF lately has been hogging CPU on certain idle sites, just freeze their DOM & JS execution.

Great add-on, thank you! Would it be possible to add an option to disable all tabs except the current one? That would be incredibly useful.

Great idea, but didn't work for what I wanted it to do (Stop nazibook from refreshing when I didn't tell it to) and the settings menu wasn't exactly clear

Extremely customizable, convenient, and does exactly what you want it to and more. A great extension for saving battery and memory whilst retaining any information you have on these pages and won't put tabs to sleep that have important information on them. Great extension.

It's amazing! Exactly what I needed

EDIT: Two days later, no answer to a simple question, and this extention not working may be interferring with other extentions. "Where is the 'tab action button'?"

So, I don't really think it's one star, but I'm out of ways to get an answer. I don't see anyother way to contact the dev besides logging into their GitHub page, where the same question was asked by another user last year, with no reply.

In the support documention, it says that you can mouse over the "tab action button" to find out why a tab isn't being discarded. Where is this button? What does it look like?

Please answer; the extention used to work well for me, and now it isn't working and I can't even troubleshoot why.

It seems to work alright, if only lightening the memory load a little bit. The big issue is that it doesn't seem like it's in active development anymore; it's been 5 months since the last commit to the repo, and Firefox-specific version of this extension is a few years old now. It might be best to just ask Mozilla to implement this kind of functionality directly.

1 Star. Breaks random websites for no apparent reason, i.e. they don't work anymore at all

This add-on saved the day. My mac fan automagically stopped spinning.
