rustup install stable
rustup default stable

This but as root, if you have a bad installation.

madjoe commented on 2021-07-24 16:51

This error is caused due to a bad rustup installation (unknown reason).

To fix it type:

rustup install stable
rustup default stable

But unfortunately, even after I fixed this issue, I still couldn't install it on my system since it made my root partition run out of space (even though I still had 16GB available!). I ended up installing librewolf-bin instead.

I tried building in a clean chroot with buildpkg -cp <folder with PKGBUILD> (I'm on Manjaro) and without the throttling you suggested I do previously. I got the same error.

Thanks for the help so far.

Hm, I can only imagine some environment variable for rustup usage messes things up / causes rustup to be called (by default it's not used / needed during the build process, only rust is needed as a package). You could check for something like this, or try it in a clean chroot ( )

When trying to install on my KDE Plasma, I encountered this error:

ZorinArch commented on 2021-07-16 09:16

Hi, please add some patches from firefox-appmenu to this package to be more friendly with KDE plasma.

lsf commented on 2021-06-08 12:12

That shouldn't happen, unless you've changed some settings (like resistfingerprinting) – maybe you could check that?

There have been a few larger changes in the librewolf.cfg in one of the past few releases – have you checked if maybe your librewolf.cfg is still an old one? (a librewolf.cfg.pacnew file should be created if you had changed something in your librewolf.cfg before updating the package – a warning/note about this is displayed during the update process, but maybe that was missed somehow).

Librewolf 89.0 receives error messages from chase, mewe, and some other web sites to upgrade your browser. For instance Chase gives this message:

We don't support this browser version anymore. Using an updated version will help protect your accounts and provide a better experience.

Update your browser

Whereas the former version there were no complaints

lsf commented on 2021-05-25 09:05

@Hyolobrika: Hm, that's quite odd.

Would you care to give building it in a clean chroot a try (as outlined in )? There might be something in your build environment / system that messes things up. Unfortunately, it's not really a "very helpful" error, so atm I can only give some very vague attempts at how to find out what's going on there / mitigate it – sorry about that!


Remember that motion mark is a very specific test of browser performance. Which gets a bit more relevant once you look at canvas / canvas permissions as well as webgl/webgl2 etc. Some of those settings are restricted/changed in LibreWolf, so that's probably where you'd have to start looking at what's causing it – PGO/LTO shouldn't be the cause here.

To give you a starting point: There's an issue open that might be related at – if you find something out (eg. which specific settings might trigger that kind of performance degradation in motion mark), it would be great if you could tell us! :)

Cape commented on 2021-05-25 01:14

Wow! So i built this package and performance in motion mark - compared to binary furryfox - is complete garbage!

furryfox score: 364 LibreWolf score: 35

I don't even care, but I'm curious to understand why? This is also a PGO+LTO optimized build, right? Maybe the profile run didn't work as expected? Is there something to look for?
