Should Firefox stay the default browser in Fedora Workstation?

I know it's powerful, it has a lot of extensions, and it's popular. But
it's integration with our desktop is lacking and getting worse all the time.

Here's a list of things Firefox lacks in Fedora:
* GPU acceleration

It's supported by Firefox. But it depends what do you actually means - there are many layers of acceleration. Can you be more specific here? Do you have any #BZ?

I don't have BZ numbers for this because I don't know which bugs are really relevant. I also don't pretend to know a lot of the internal architecture of Firefox.

Here is what I do know:

1. about:support says no windows are accelerated

2. WebGL is very slow

3. Various people at MozCamp last year told me that yes, Firefox still doesn't use GPU acceleration on Linux. Some of them claimed the GTK3 port will make it possible, but they had no technical details to give me.

4. At some point, mesa drivers were specifically blacklisted in Firefox, but afaik that was for mesa older than 7, and we are on 10.2 on Rawhide today and Firefox still reports no acceleration

5. This seems relevant https://bugzilla.mozilla.org/show_bug.cgi?id=594876

6. Setting layers.acceleration.force-enabled to true does not do anything

* Integration with the desktop's geolocation services
* On that note, geolocation doesn't work at all in Fedora's firefox at
the moment

It's because we need an API key to Google Geolocation service. If Evince has the API key, we can use it in Firefox too (see rhbz#1063739).

Evince doesn't use geolocation afaik - it's a PDF reader.

Also, afaik there's no app in Fedora with Google API key. I strongly recommend we use the Mozilla Location Services at least until GeoClue2 support is implemented in Firefox.
Geoclue2 will mean GPS devices (and theoretically cellular tower IDs, I don't know if that's implemented) will be supported for more accurate location. GeoClue2 uses the Mozilla Location Services by default as well.

* Integration with the desktop's notification system

That's true. It's on our TODO list. Patches are always welcome :)

Nice to hear.

* Support of url scheme handlers (this used to work)

Can you point me to #BZ? I'm not aware of it.

Seems that you found it already. For later reference: https://bugzilla.redhat.com/show_bug.cgi?id=1105640

* UI that matches the rest of the desktop (without installing 3rd party
theme and extensions)
* GTK3 support

Will be addressed by Gtk3 port. Our optimistic target is Firefox 32.

The GTK3 port addresses the GTK3 support, but it doesn't alter the browser's UI: it looks and behaves on Linux just like it does on Windows.

Try installing the Firefox GNOME theme: https://github.com/gnome-integration-team/firefox-gnome and see how Firefox will suddenly look at lot more like other apps do, and follow the GNOME HIG more closely.

Unfortunately, there's no real solution to this as we can't ship the extension by default (I listed the reasons in other places in this thread) and upstream still belives Firefox should look the same on all platforms instead of looking native to the platform and more similar to other apps in the platform. This might work well for Windows where every app looks differently, but GNOME, much like iOS, has a well defined set of Human Interface Guidelines. All GTK3 apps look roughly the same, with symbolic icons, similar tabs, similar buttons. Firefox looks extremely different.

* High-DPI support

Already on TODO list - https://bugzilla.mozilla.org/show_bug.cgi?id=975919

* Touch input support

On progress - https://bugzilla.mozilla.org/show_bug.cgi?id=978679

Great to hear!

Some of those issues are being actively worked on, other have incomplete
patches in upstream's bugzilla with nobody working to finish them, and some
of them seem to be issues that will never be solved (such as making the UI
feel more "native" to GNOME).

Can you be more specific here what is leaved behind? All upstream Gtk3 bugs should be registered to:

https://bugzilla.mozilla.org/show_bug.cgi?id=627699

And as you can see, various people are submitting patches and the project is moving rapidly. And I'm picking the "unowned" bugs.

Not a gtk3 issue, but it seems that GeoClue2 support has an out-of-date patch and nobody who knows how / has the time to implement it

https://bugzilla.mozilla.org/show_bug.cgi?id=485472

Meanwhile, Epiphany (GNOME Web) keeps getting better and better, perhaps we
should consider it as the default?

Mozilla invests money and people to the Firefox Gtk3 port (for instance Collabora writes the gtk2 plugin support code - mozbz#624422) and so we should do. It would be a wrong signal from us to leave the Gtk3 Firefox behind.

I appreciate you took the time to reply here even tho it has already been decided that Firefox will remain the default.
