Overall, after usinig this extension for several months, I really like it. The reason I have only given four stars is because there is one addition I would like to see...

I will explain. I like the level of control provided by the Suspender settings, being able to whitelist, control which tabs get suspended and for how long, being able to suspend the suspender for X period of time, and so on.

Every time I have had a need to alter the suspending of my tabs I have been able to do it. However, today I could not. I wanted to keep the extension running in one browser window, but suspend operation in another browser window (EG it works for all tabs in window 1, and disabled for all tabs in window 2 - obviously whitelist applies still on window 1)...

However I was unable to do what I wanted. I have been able to fine tune Tab Suspender exactly the way I want (or in a similar equally effective way) every time I have needed to. Only this time, I could not. Save temporarily whitelisting all the tabs in window 2 (and thus any tabs in window 1 for that site/domain get whitelisted also), there was no way to achieve the desired effect.

This is the reason I do not give 5 stars, even though I do want to. In all likelihood, having multiple firefox windows open is not the default mode of operation, and so I would put this additional feature into the "Pause Suspender" settings page, and along with the "Pause Suspender for X period of time" control, have a ticklist/toggle to choice which window(s) to pause (or which window to not pause, depending on how you want to word it).

Good features, but making a notification each time a tab is suspended no thanks.

Work well BUT we need an option to NOT suspend an active tab (even without sound or input), if i have a tab open, i don't want to suspend it, even if my mouse is not on it :/
I only want to suspend tab that are not open
Edit because i can't answer directly ;
If i have a youtube 3 Youtube tab opened, even if one is "active", they will all be suspended if they don't have sound playing or have input, but the one that are opened (visible on the window, sorry i don't know how to explain it better) i don't want that one to be suspended

Please check the latest version:
It suspends immediately all the new tabs that I opened through "Open Link in New Tab" and "Open Link in New Container Tab".
And as long as I click away, i.e. switch to other tab, some tab, e.g. the homepage of this addon on mozilla will immediate become suspended, after it become an inactive tab.

(I am using LibreWolf 137.0.2-1 in Windows 11 x64)
