It could have better with the header title when showing title while suspending that exists URL layout, I'm more used to it like the great suspender.
Additional, It doesn't reduce RAM usage, it's same as active tabs. :-(

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

Suggestion for dev...if you could specify the website TITLE on each of the suspended pages (perhaps right above the image near the top of the white box)...then this would make navigation so much easier when clicking across multiple suspended tabs. Hopefully this can be added in a future update! Great addon though, thanks.

It seems the suspended tabs disappear after every update?

Cool addon! Keeps my browser snappy by suspending inactive tabs without breaking a sweat. The UI’s clean, way better than clunky alternatives, and I dig how it skips tabs with unsaved forms or media. The ZZZ animation’s a bit gimmicky, but it’s fine. Wish there was a toolbar button to toggle it off quickly when I’m multitasking. Still, it’s solid for managing my tab chaos. But please, more updates.

The biggest limitation that this extension has is the inability to export your white list or sync them to your Mozilla account which then would sync across your devices.

Definitely working as intended! Functions akin to The Great Suspender/the Marvellous Suspender. Haven't tested the RAM consumption yet though.

Would love an option to manually suspend a tab, and also have the tab title be the original title, instead of showing "Suspended:...". As much as this is helpful in differentiating between suspended and active tabs, when you have multiple tabs on one window, it's just a row of "Suspended"s.

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)

It's working, but may I ask for "Whitelist" or something? I don't want to suspend specific websites

Features work as expected. Kind of like the Great suspender chrome extension.
