The Wayland backend is available as an extra desktop entry. Please
report all wayland related issues to #BZ as usually.

Call for testing - Firefox 57

Hi folks,

let's have some fun with upcoming Firefox 57 a.k.a Firefox Quantum.

Retired package - xulrunner


Xulrunner is no longer supported by upstream and contains known security
bugs so we decided to retire it from master (will be still available for
Fedora 26).

If any project needs that package it has to bundle it.


Firefox 52 - ALSA backend disabled


ALSA backend is no longer available in official Fedora Firefox builds
[1] since it has been deprecated by Mozilla and no longer maintained [2].

If you still want to use ALSA on Fedora builds, you just need to rebuild
Firefox with such option. Just set "alsa_backend" to 1 and run the build.

flatpak app launch script


I feel that launching a flatpak app from command line a bit regression
from rpm packages. It's really different to type:



$flatpak run org.mozilla.Firefox

Especially when "flatpak run org.mozilla" carries no information for
user, they just want to launch the app and don't care if that's rpm,
flatpak, snap or whatever. The ALT+F2 is affected too by this.

And why to care about about command line anyway?

Firefox on Wayland

Hi Folks,

Firefox with native Wayland support is available here:

<a href="" title=""></a>
<a href="" title=""></a>

It's an official Fedora Firefox package (47.0) + Wayland patch and it
replaces your distro FF. Runs under X unless you specify Wayland display
- see "Installation Instructions".

Please report any crashes/issues at bugzilla or ABRT and note the
Wayland version.


Firefox - call for testing (Gtk3 effort)


we see many Gtk3 crashes in Firefox recently
(<a href="" title=""></a>) which comes from
Gtk3 system library.

If you's like to help here, please install latest FF updates from koji:

F23: <a href="" title=""></a>
F22: <a href="" title=""></a>

and also enable the ABRT tool. If Firefox crashes please submit the
crash stat to ABRT retrace server.

That would help up greatly to investigate root of this problem.


Xulrunner - intent to remove from Fedora 24


does anyone use the xulrunner package? (and gecko-devel actually).
Mozilla does not maintain it any more and the XUL as technology is going
to be removed/deprecated. I'd like to remove the package from Fedora 24.


Retired - nspluginwrapper

Hi Folks,

I'm going to retire and remove nspluginwrapper from Fedora 24 and newer
[1]. Firefox and Chromium does not use that any more.

Please speak up if you need that.

Firefox testing - offscreen surfaces and OMTC


I'd use some testing for new Firefox feature - offscreen surfaces [1].
It may also fix crashes when OMTC is enabled [2]. Browser should be a
bit faster with those features on.

How to test?

- Install Firefox 40 on Fedora 22,23,Rawhide (you'd need Gtk3 build)
- go to about:config, click to any key and add a new one, boolean type.
The new key name is "layers.use-image-offscreen-surfaces" and set it to
- enable "layers.offmainthreadcomposition.enabled" which may be disabled
- restart your browser.

And you're set now.

Rapid release for security updates

Hi guys,

is there any mechanism how to speed up release of critical security
fixes by Fedora update system?

For instance Firefox packages are released *week* after official Mozilla
release which is really bad.

Any idea here?


Flash plugin 0-day vulnerability in the wild


There's a live 0-day flash vulnerability which is not fixed yet [1][2].
If you use flash plugin I recommend you to enable the click-to-play mode
for it.

There's also a Fedora Firefox update with such change [3].

Join to Mozilla Location Service in Fedora

Hi Folks,

as you may know [0] Firefox in Fedora [1] is using Mozilla Location
service [2] as a location provider instead of the Google one.

I'd like to ask you to join the project, install the Mozilla Stumbler
application [3] and help to improve the location accuracy.


p.s.: Yes, I know about GeoClue2, see [1] for the discussion.

Firefox Gtk3 test package

Hi guys,

first $SUBJ is available at:

<a href="" title=""></a>

It's just a src.spm and plugin support it not finished (don't browse
youtube ;-)) but may work as a preview.

I'll provide Fedora builds and repo later.


Firefox / Thunderbird 17 ESR for Fedora 16/17

Hi guys,

as the subject says there are test packages available for your beloved
Fedora's. Especially Thunderbird 17 (Earlybird now) needs some love from
you (the 17ESR line is going to be a background for the future ones) so
it would be great if you can install it, run it and report any issues.
All instructions are at:

<a href="" title=""></a>

NOTE: All those packages are pre-release and are targeted to experienced

Your Mozilla Team.

Heads up - firefox desktop file change

mozilla-firefox.desktop to firefox.desktop. See bug

Seeking for package review - Berusky 2 game


Berusky2 is a 3D sequel of Berusky and former commercial project:

I promise the spec file is tinny and reviewer friendly :)


Heads Up - New Firefox update


there's a new Firefox update waiting in Bodhi and we can't push it to
stable because of new rules.

Heads Up - xulrunner 2.0 in rawhide (F15)

There's a new xulrunner/firefox in rawhide. The API (js too) is slightly
incompatible with the 1.9.2, there is a new XPCOM modules registration
and so on, see:

<a href="" title=""></a>
<a href="" title=""></a>
<a href="" title=""></a>


Head-up - new firefox in rawhide


a new firefox (3.6 beta 2) just hit rawhide (a.k.a f13). There are some
changes which affect everyone who builds with xulrunner-devel-unstable

Mozilla decided to merge all include directories to one (mozbz#398573)
and stop shipping stable/unstable packages. So all headers/libraries are
merged to one big xulrunner-devel package (with respective pkgconfig
files) and xulrunner-devel-unstable has been removed.

What does it mean for you?

1) Change xulrunner-devel-unstable to xulrunner-devel in spec.
