I used this extension for Zen Browser and it's been proven perfectly compatible to the point where even my tabs in other workspaces can also be suspended into inactivity too. This is not something that Auto Tab Discard can pull off with workspace tabs.

Works great but wish there was 2 or 4 hour option, or a custom time option

Lightweight, close to no memory and CPU usage. It's compatible with Zen as well.

I cannot for the life of me figure out where the controls are? as shown in the screenshots ! I'm sure its simple but would someone post how to here for ppl like me? TY

Can you PLEASE add keyboard shortcuts?

That is the ONLY thing missing from this add-on.

Actually makes any firefox based browser usable, clear, simple to control/configure.

i hope suspended tab not active when single click...

Automatically suspends tabs that stay inactive for a certain time (5 sec to an hour), without losing the context (e.g., if you are in the middle of watching a Youtube, it doesn't forget where you are).

When you click on a tab it re-activates it, and goes from where it was. You can also whitelist tabs that you want to stay always active, like gmail, or whatever else you may have possibly pinned.

Some users said it does nothing, or that it doesn't work, but it's user error, or maybe older version had such issues. For me, it's perfect, and does exactly what it claims and I needed.

Does what it's supposed to do. Please consider adding 3 min suspender! Thank you : )

YES! Finally something that adequately curtails the poorly implemented tab management within FF's backend. Before installing this, I'd get these frequent CPU/memory spikes and my MBA fans would ramp into overdrive—all because I dared to have (gasp) a dozen or so tabs open across (BIGGER GASP) two different windows, even if there are no YouTube videos playing, even if a majority of the tabs don't seem like they should be resource-intensive.

For someone who doesn't have the ability to augment their current RAM setup, this app is a total lifesaver! All its core settings (timer, whitelist, ignore functions) work like charms. Now I can use my browser without needlessly bogging my entire system down. What a concept!

Thank you, Pradeep! If there's any way to show you some direct support (Paypal, Venmo, etc), reach out!

Great tool for people like me who are living on low RAM. please add a 3 minutes window/ custom window for "suspend after dropdown"

It gets 3 stars because it does, in fact, suspend inactive tabs. It only gets 3 stars because the time limit given does nothing (it's always 5 minutes even when I set it to 1 hour) and the "Do not suspend this tab" checkbox doesn't work either.

This add-on works (as my memory drops dramatically in a matter of minutes after install with over 100 tabs open) but nowhere can I find the options to set suspend time, whitelist urls, ignore/disable items (as shown in your screenshot). How about some basic information on where this can be found & what to expect on install?? I've uninstalled/reinstalled/rebooted to no avail. Moving on to another add-on

It works great and has good utility to manage what type of tabs (whitelisted, pinned, audiable) are suspended. Its downside is it can spike your disk usage and cause Firefox to not respond intermittedly.
