Situation: I've compiled firefox-50 on arm64 against gtk+:3. I don't even have gtk+:2 on my system. Firefox works fine. Problem: When resolving world package dependencies in depth, portage wants me to install gtk+:2 for firefox. Workaround for me (I am using paludis/cave): * Open the two files /var/db/pkg/www-client/firefox-50.0.1/DEPEND and RDEPEND * Change ">=x11-libs/gtk+-2.18:2" into ">=x11-libs/gtk+-2.18" Remarks: I don't fully understand the firefox ebuild. But IMHO the firefox installation somehow marks itself still dependent on gtk+:2.

Thanks for the fast reply. I just tried firefox-50.0.2 but got this.

So all Poly-C's patch did was remove the RDEPEND on gtk+:2 which allows you to install it if the build system didn't actually need it. The problem is, I am still fairly certain that there are components within the firefox codebase that do still need gtk+:2. This may change in firefox-53 and above, but for now, I believe that it is indeed still a requirement even when cairo-gtk3 is the toolkit requested. I'm going to revert this commit until such time as gtk3-only builds can be ensured.

What's the status on this? Why are current firefox ebuilds not depending on gtk+:2? The dependencies should reflect what's actually required, not what you wish was required =)
*** Bug 613524 has been marked as a duplicate of this bug. ***
Dependencies have been added back. So firefox etc will continue to depend on gtk+:2 until such time as flash support is dropped; although npapi plugins in general are banned, the functionality is still there to support flash and so the dep is still required.
If you feel I have closed your bug and it is still a current issue, please reopen and update it completely. We will not work bugs that have no ebuild in tree any longer or can not be reproduced with a current system. Thank You for your support and understanding The Mozilla Team
