130 The mach build system (Python scripts) can be somewhat unreliable: if
131 the build fails and reports an Error, it can still return a status of
132 success, causing a scripted build to try to install (which does not rerun
133 the build), fail during the preparations for installing, but still exit
134 with a status of success. Also, on occasion it may limit itself to only
135 running one set of jobs - that will make the build take about 3 times as
136 long as running with four sets of jobs.

543 Occasionally, getting working sound in
544 <application>firefox</application> can be a problem. Although upstream
545 prefers pulseaudio,
546 on balance using <application>Alsa</application> may be easier.

550 If you enabled <application>Alsa</application> for sound, you may need
551 to alter one variable to get working sound. If you run
552 <command>firefox</command> from a term and try to play something with
553 sound you might encounter error messages like:

557 <literal>Sandbox: seccomp sandbox violation: pid 3941, tid 4030,
558 syscall 16, args 48 2147767296 139909894784796 0 0 0.</literal>

562 That was on x86_64, on i686 the syscall number is 54. To allow this
563 syscall, in <command>about:config</command> change
564 <command>security.sandbox.content.syscall_whitelist</command> to 16
565 (or 54 if using i686).

569 If you use <command>pulseaudio</command> in a Desktop Environment, it
570 might already be started by that DE. But if it is not, although
571 firefox-57 managed to start it, firefox-58 did not. If you run
572 <command>firefox</command> from a term and this problem is present,
573 trying to play sound will
574 encounter error messages warning <literal>Can't get cubeb
575 context!</literal>
576 </para>

578 <para>
579 The fix for this is to close firefox, start pulseaudio to check it
580 does start (if not, read the information on Configuring in <xref
581 linkend="pulseaudio"/>) and restart firefox to check it is working.
582 If it now works, add the following to your <filename>~/.xinitrc</filename>:
583<phrase revision="sysv">
584<literal>pulseaudio --verbose --log-target=syslog&amp;</literal></phrase>
585<phrase revision="systemd">
586<literal>pulseaudio --verbose --log-target=journald&amp;</literal></phrase>
587 (unfortunately, on some systems this does not work).

591 You may wish to use multiple profiles within firefox. To do that, invoke
592 firefox as <command>firefox --ProfileManager</command>. You can also
593 check which profile is currently in use from
594 <command>about:profiles</command>.

598 Although WebRender (using the GPU for compositing) is not used by
599 default, it now appears to work well on supported hardware (ATI, Nvidia
600 and Intel GPUs with Mesa-18 or later. For an explanation, please see
601 <ulink
602 url="https://hacks.mozilla.org/2017/10/the-whole-web-at-maximum-fps-how-webrender-gets-rid-of-jank/">hacks.mozilla.org</ulink>.
603 The only downside seems to be that on a machine with limited RAM it might
604 use more RAM.
605 </para>
606
607 <para>
608 To check if WebRender is being used, look in about:support. In the Graphics
609 section Compositing will either show 'Basic' (i.e. not in use) or
610 'WebRender'. To enable it, go to about:config and change gfx.webrender.all
611 to True. You will need to restart firefox.

615 It may be useful to mention the processes from firefox which can appear in
616 <command>top</command> - as well as firefox itself, there may be multiple
617 Web Content processes, and now an RDD Process (Remote Data Decoder) which
618 appears when playing web videos encoded with av1 (libdav1d). If WebRender
619 has been enabled, a GPU Process will also appear when firefox has to
620 repaint (e.g. scrolling, opening a new tab, or playing a video).
