How do I enable overlay scrollbars in Firefox?

Question

I like the overlay scrollbars that come with natty beta 2 by default! How do I enable them on fx4?

Solution 1

That is currently not possible, due to the libraries that Firefox's user interface is written using.

There is a bug report that you can mark as affecting you: https://bugs.launchpad.net/firefox/+bug/767040

Solution 2

This works well in 11.10. Try it in 11.04.

I've tried it in 12.04; it does change the size, but not the color.

Solution 3

If the intent is to improve contrast for the existing Firefox scrollbar (not the overlay), a workaround is available in the form of an add-on which has been reviewed here and is available via from the official Firefox add-ons page. To quote from there: "This add-on is mainly for people, who want different "high contrast" scrollbars for their default Firefox theme. These scrollbars can be more kindly for eyes".

I don't use that add-on since I already have the Stylish add-on installed: this add-on allows one to modify scrollbars. My simplistic tweak is in the comments section of the first link.

@Ingo If they can enable them in all other default apps, why did they leave fx4?

[nik90]

I think applications like firefox, libreoffice have a different framework...for instance they had to manually program global menu for these applications make it work...I think it is something got to do with that.

@Ingo @Nik where can I request to have such a feature?

Not necessary, it will be implemented for sure. They are probably already working on it :)

@Ingo great!waiting for it!

It didn't happen with 11.10. So now the question is: what about 12.04?

[Mihai Capotă]

The developers are still not working on this. You can also vote on the Mozilla Bugzilla bug, #693146, to increase the importance of the bug.

The question is whether this will ever happen, now that Ubuntu switching to Unity 8.
