Must install for mega taskers. Before quantum upgrade to FF there was lots of addons to manage memory and features. Then as firefox became like every chromium based browser and as bloated I didn't find anything until this.

Avg mem usage went from 75% of my 64gb of ram to 25% enough said.

Would like to see more functions with add-ons like tree style tabs in the future.

جربتها قلت ممكن يكون الاتصال اسرع اذا نامت صفحات الاعلان لكن نفس تقطع الاتصال

I am now so exicted that this extension acutally works!! Cannot believe it! I don't know anyone out there is like me always have over 50+tabs opened. You said that is what bookmarks for? Nope. Let me tell you, if you put into the bookmarks you will just forget it. If I keep them opened, I will notice them, and never forget what I left whether or not need to continue or finisht it. Before using the extension, my Firefox always ate up 16+GB memory, I needed to upgrade my PC memory to 32GB, as I am also a programmer working with different platforms that use heaps of memory. After I install this extension, my Firefox only uses 1.6GB, 10 times less, I am not joking. Cannot be happier to find the extension. The only thing that can be improved is if there are more explanations on each option would have been better. I don't know why Firefox team cannot do it...after so many years...

Would be excellent if discarded tabs could be refreshed/bypass cache when reloaded.

This one is a must! Life, CPU and battery saver!

The exceptions don't work, keeps closing my youtube tabs.

This has been one of three esential plugins (the other 2 security-based) I have used without issue on both Windows and Linux synced copies of Firefox. As advertised. I dig it, other people dig it; you will - 'bets-on' - dig it too. Be a cool cat and kick some tabby-tab-tabs out of your resource reserves. Firefox could focus there too btw ;) Thank you Mr Neomy kind and generous gentleman he is ('bets-on' always is.)..

It's all too buggy. It keeps suspending pinned tabs which are also added to the exception list, or it will randomly suspend tabs in less time than was set.

Loving the addon so far ! Been using it for months now and had zero bugs, it has simply just worked 100% of the time, which is amazing.

I have a feature request though which in my opinion would add to it's value immensely.

As the core goal of this is not necessarily reducing the number of loaded tabs, but rather reducing CPU (and by extension, battery/heat/power) usage, RAM and disk I/O. So what would be great, would be the possibility to unload tabs by their resource usage. This data is available in firefox profiler capabilities but it's rather cumbersome going checking the data by hand through the debugging tools.

The feature could be added as a new condition to be mixed with others, like after X open tabs unload tabs which use >X% CPU and/or >X MB RAM / unload the next highest resource usage tab / after X minutes close tabs using X% cpu or X MB RAM / only close tabs which use >X resources.

Adding a tooltip when hovering over a tab which displays their CPU/RAM usage would be neat too.

For my use case as I've moved the FF profile to ram disk and I have plenty of RAM, I don't really care about disk I/O or RAM usage, but badly coded CPU-heavy scripts on some sites makes browsing a slog (not to mention killing the battery when on a laptop), hence this plugin. But a static site which runs very little to no scripts does not really contribute to the resource usage, unlike some badly behaving sites.

And systems which are more starved of RAM, could start unloading tabs by highest RAM usage instead, when total RAM usage exceeds X MB as a condition, for example.

Anyway, just my two cents for now, and keep up the good work !

When left click to discard tab, Can't access Options Page.
