Installed but no UI is displayed. Therefore uninstalled

GOD

The only add-in I could find that successfully manages my 9 windows and more than hundred tabs. Search is very useful and elegantly implemented. Organizing tabs and moving them between windows makes this add-in my every day tool. Although I would like that it has more options for design customizing (column height for example).

This module slows down Firefox sooo much that it was almost not possible to use Firefox anymore... I do not recommend it at all

immediately pegged my cpus and rendered firefox totally unresponsive; plus, the UI that renders by default (I can't even tell if there's a way to change this, it was so unresponsive) takes up way more of the screen than I expected. I ended up having to kill the process and hitting the extension manager to remove it, which also made my previous session disappear, so I couldn't even get back those tabs.

fine addon :)
The movable Tabs in the dropdown list and the mark of actual tab makes it my fav.

But you could copy following from:
TabSearch https://cup.aihedy.com/en-US/firefox/addon/tab_search/

- URL in the List beneath the title.
- Amount og tabs in the icon.
- Search also in the UR-Text.

thx :)

Very nice web extension. To make it great, could you please consider adding the feature to search the URL's (not just the tab-titles)? Then it would be just perfect.
Thanks

Is a hidden gem very useful.
