highlight tab groups when hovering them


(Firefox Graveyard :: Panorama, defect)

Not set

We want them to fade to a darker grey - that's sufficient for now to see how it feels. The specific color code will be picked by the UX team when this is ready.

As tabs are not children of tab groups, hovering over tabs would not highlight the tab group using CSS, as far as I have tried. Only hovering over the tab group itself works. I'm going with a Javascript solution if the DOM structure cannot be modified. Any other ideas?

What do you think?


Yes, unfortunately there's no way to do this via a single mouseenter listener or a :hover selector. You should check which group contains the currently hovered tab and highlight the group accordingly.

BTW, modifying the DOM structure so that tabs are real descendants of groups would be ideal but that's a whole lot of work so maybe not the best place to start :)

Feel free to ping me on IRC or just ask here if you have any questions.

Panorama has been removed from Firefox 45, currently in Beta and scheduled for release on March 7th. As such, I'm closing all existing Panorama bugs.

If you are still using Panorama, you will see a deprecation message in Firefox 44, and when 45 is released your tab group data will be migrated to bookmarks, with a folder for each group. There are also a few addons offering similar functionality.

See for more info.

We're removing Panorama because it has extremely low usage (about 0.01% of users), and has a large number of bugs and usability issues. The cost of fixing all those issues is far too high to justify, and so we'll instead be focusing our time and energy on improving other parts of Firefox.
