Tab Manager Plus Set to “Open in own tab by default” Set to “Dark mode” Set to “Vertical view” – very important

You can live search your tab titles to select them

You can open all selected tabs in their own window

You can close selected tabs

You can “discard” tab contents (different from close, the tab is there but content is gone)

You can highlight/select duplicate tabs

You can hide not selected tabs

You can pin selected tabs (unfortunately, they still only appear on the one window they are pinned to, they just get pinned to the left of the tab bar)

You can drag and drop selected tabs to another window of your choice, both the representation of that window in the TMP tab, but also into the other firefox window itself. That means, drag and drop from here, is the same as pulling out a tab out of a normal firefox window !

Cannot search text inside of tabs, especially not sleeping tabs

Sometimes I press the TMP button and I just get a bluegreen screen, doesn’t work until I close many windows and tabs

I would prefer real dark mode with my preferred colours

I would like to easily drop&close tabs into bookmark folders reliably !
