Reduce your memory and CPU usage by up to 60% and indirectly your battery consumption by automatically suspending the tabs you aren't using.

How many tabs do you have open that you have not used in hours or even days? That could be making your system run slower. With the Tab Suspender you can set how many minutes to wait before suspending an inactive tabs among many other options.

Features:
• Whitelist urls or domains that you do not want to suspend (You can still manually suspend them by using the menu)
• Show a screen shot of the page just before it was suspended
• Detects tabs playing audio and will not suspend them if you don't want it (experimental)
• Detects tabs that contain active forms and will not suspend them if you don't want it
• Optionally, do not suspend tabs if on battery power or no network connections
• Dark mode compatible!
