Wonderful extension, thank you very much for maintaining it. Keyboard-driven "selection -> action" interface for your tabs! afterwards, you can easily close the tabs, create a Tab Group, or drag them to a new window/a Tab Group.

(I've been using various extensions to get a subset of this functionality, and this one is both most useful and the least bloated. I wish discoverability of extensions was better because this one was NOT easy to find.)

This is great, thank you! It would also be great if directional included an incremental option, for instance, to select the "next" tab to the right, while pressing it again would select one more so you could get a fine selection of tabs that are side-by-side.

Edit: The above and beyond is now supported. This add-on is a true gift. Beautifully done, with detailed descriptions of everything it does and keyboard shortcuts for it all. Thank you so much, again, for making it! <3

Brilliant fix for an ongoing annoyance! I've been searching for a way to save multiple tabs to a Simple Tab Group at once without having to choose and send each tab separately. Happy to have found Select Tabs. Thanks, Lionel Wong!

PS: Thanks for your follow-up. Haven't seen evidence of a bug yet, will keep an eye out. Thanks for your attention to the quality of your add-on!

It's a really useful add-on. You can select the same domain as that tab or the parent/sibling/child tab. After selection, you can use the firefox native commands (move to new window, close, refresh, ...) in the tab context menu, and you can move it by dragging it or drag it to another window.
