It has to be set every time you start Firefox, a waste of time and NOT WORKS

Doesn't respect the time set before inactive tabs are to be discarded and just discards tabs after the default 10 minutes.

This is very good. I have loads of tabs open simultaneously and was having problems with high memory usage. This plugin instantly took care of the problem. The configuration can seem a bit daunting at first but it's worth taking the time to go through and understand every setting to get the the most out of this add-in.

I notice certain "special tabs" are not being discarded, for example, Sidebery folder tabs, Firefox Preferences pages, and add-on options pages. Regarding Sidebery folder tabs, perhaps they are being seen as active all the time because Sidebery is active and those tabs are part of it? This doesn't bother me, but I thought I'd mention it in case it's not intentional.

My only tiny criticism would be the lack of documentation, since some settings are somewhat cryptic especially if you are not a techie. Eventually I managed to figure out almost every setting through trial and error.

I'd like to sugges a floating Save Options button that's always visible, thereby eliminating the need to scroll down to the bottom each time settings need saving. This would make experimentation less time-consuming.

In short: A fantastic add-on. Big thank you to the author/authors!

Why not rename it to something that reflects its feature better? I've known about this extension for a long time but never installed it because I initially thought it was meant to close tabs.

working great and i hope creators will continue developing it

This extension is nothing short of revolutionary for heavy browser users like me. As someone who regularly juggles dozens, sometimes hundreds, of tabs across multiple Firefox windows, I've experienced firsthand the strain this puts on system resources. With only 16GB of RAM on my Mac, I often found myself teetering on the edge of 80-90% memory usage, a situation that even dedicated memory cleaning apps struggled to alleviate for more than a few seconds

Unbelievable Performance
Auto Tab Discard is on a whole different level than other tab management solutions I've tried.

• Dramatic Memory Reduction: With around 50 tabs open, the extension's impact was immediately noticeable. However, the true test came when I pushed it to the limit
.

• Handling Hundreds of Tabs: Upon opening hundreds of tabs across several Firefox windows, my system's memory usage skyrocketed to 90%. Activating Auto Tab Discard resulted in an astonishing drop to 53% memory usage - a level that remained stable!! What?!
?

• Consistent Performance: Even after adding another 80 tabs in a new window and starting a YouTube video, the extension managed to keep memory usage hovering around 50%.

In my opinion, if you are a power user and struggle with browser & memory issues from having tons of tabs open, this extension’s ability to dramatically reduce memory consumption while maintaining a smooth browsing experience will shock you. At least, it has shocked me. It has fundamentally changed how I manage my browser workflow, allowing me to keep numerous tabs open without sacrificing system performance. Frankly, I’m gobsmacked.

Works great, but I'm worried that it hasn't been updated in two years.

Absolutely fantastic addon. I'm a tab hoarder and this cut my ram usage from 45GB down to 20GB! Very impressed!

This add-on works very well for improving performance, is easy to use, and has lots of customization options. However, one feature that it's sorely missing is the ability to view a tab or bring a tab into focus without un-discarding it. This is a major issue for me because I scroll through tabs to navigate my browser, so I end up loading a bunch of tabs I don't want to load. If there was an option to only un-discard a tab when I click in the tab instead of when I open it, this would be perfect.
