Loaded Tabs Limiter od Shajirr

This addon keeps the number of currently loaded tabs below a specified limit, preventing a situation when there are too many loaded tabs eating RAM for no reason.

Usage instructions

• Clicking the addon icon toggles the addon's active/disabled state.
• To quickly open the Options menu, right click the addon icon -> "Options"
• Addon icon show the number of currently loaded tabs, background color changes depending on how close it is to the limit
• You can mark a tab as persistent, so that it won't be unloaded by this addon - activate said tab, then right click anywhere on the page background -> "Make this tab persistent"

Options

• Loaded Tabs Limit - how many tabs can be in the loaded state max
• Unload pinned tabs - if enabled, pinned tabs will be unloaded too, by default they are skipped
• Count persistent tabs towards limit - by default, persistent tabs are not counted, so you can have a max number of regular loaded tabs as defined in the "Loaded Tabs Limit" plus any number of persistent tabs. With this option enabled, persistent tabs are counted towards the "Loaded Tabs Limit" too.
