Instead of building this yourself, please use the repository from

Not only do you skip the very time-consuming builds, but the published package also has debug symbols at Mozilla's crash reports service, which helps tremendously with finding or filing bugs for any crashes you get.

I consider this the canonical firefox-nightly package for Arch Linux.

SigLevel = Optional
Server =$arch

Alternatively, download Firefox Nightly straight from Mozilla, extract it to a writable place (e.g. ~/.local/firefox-nightly) and let it update itself using the integrated updater.

@DuKoL This PKGBUILD has only been tested with clean chroots (via extra-x86_64-build), so at the very least you need to be using makepkg -C.

DuKol commented on 2022-08-01 06:40 (UTC)

I wanted to build an update. makepkg worked fine, even if the process suggested that I should do hg update, which I did manually. The reason is that the process finished with an error message which is pretty strange (thus I did the hg update): ==> Starting prepare()... mkdir: cannot create directory ‘mozbuild’: File exists ==> ERROR: A failure occurred in prepare(). Aborting... \ The directory was made by the makepkg last time. Does that mean that I must delete it and always build nightly from scratch? Is there not a build of just changed parties? hg update didn't changed the result.

@heftig one thing that I wonder is if the package shouldn't just have an option or something to ignore whatever is installed in the system and opt for things in mozilla-central/third_party or some kind of equivalent option.

@spastorino Dang, looks like more trouble with the Python environment when building outside a clean chroot. I wish I had time to debug this further.

@DuKol Open about:profiles and set your previous profile as default. Each installation of Firefox (determined by the path) has its own default profile.

PS: Beware that downgrading a profile (i.e. loading it with 103 after it was used by 105) is disallowed by default, as it can lead to bugs and data loss. If you want to keep using Firefox release, consider copying your old profile to a new one.

Hello, I managed to build and install firefox-nightly-105.0a1+20220729.1+h1452abb71f59-1-x86_64.pkg.tar.zst

So far, so good. After running it, I was surprised it has ignored all my previous settings, extensions, passwords, etc. from 103 version. Is it meant to be such a way? How can I import all of my previous settings?

Have tried this patch ...

Got the following ...

WARNING: You are using pip version 21.2.3; however, version 22.2.1 is available.
You should consider upgrading via the '/tmp/tmp7iip15g0/bin/python -m pip install --upgrade pip' command.
flask 2.1.3 has requirement click>=8.0, but you have click 7.1.2.

black 22.6.0 has requirement click>=8.0.0, but you have click 7.1.2.

So flask is being taken from system and the other stuff is from mozilla-central/third_party so things doesn't add up. Couldn't everything be used from third_party or something?

heftig commented on 2022-07-28 18:33 (UTC)

@xuiqzy No, the debug symbols of the official builds should have identical quality.

xuiqzy commented on 2022-07-28 17:19 (UTC)

@heftig Thanks for providing the build! Does the official build straight from Mozilla also has worse debug symbols than the build from your repo? If so, why, is it about debug symbols of the dependencies?

heftig commented on 2022-07-28 12:51 (UTC)

@spastorino I think I encountered this before, but just worked around it by removing python-psutil from the makedeps, so the build container does not have it installed.

You can try patching the version check like zstandard-0.18.0.diff does for python-zstandard. Please report back if you try this.

That said, please use the prebuilt package for the reasons given in the pinned comment.

spastorino commented on 2022-07-28 12:47 (UTC)

It's failing to install for me, python-psutil on system is 5.9.1 but the package requires psutil<=5.8.0,>=5.4.2.
