Hi

Thank you for helping to test future updates to Firefox. Please appreciate that the Nightly build is very much under construction and may have unresolved issues that developers are still working on.

If you wish, you can also file a bug report. See File a bug report or feature request for Mozilla products for details.

I know and I use it for plus minus 6 years now and every time it crashes it sends a crash report next time I will just take a screenshot and post it here

Don't paste a screenshot. And you don't have to wait for another crash.

1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted (and Unsubmitted, if any) Crash Reports will appear, similar to the one shown below.
2. Copy the 5 most recent Submitted Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

Thank you for your help!

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

I'm not very familiar with Linux, but it's something with MESA drivers.

Ok cool thank you but the crashes were for the last two days and MESA only updated today but I will look into it and see if there is a workaround or solution.

Hope this solves the issue what I did in about:config → gfx.webrender.software → true

Please do not paste crash reports here.

It looks like it might also be linked to GNOME, but please appreciate that this is a Nightly build of Firefox and may have temporary problems that are still being worked on.

Sure but I don't use Gnome or any DE (desktop environment) I have been using firefox-nightly like this for a year now and never had issues. I don't use any AUR (arch user repositories) to install firefox-nightly infact I don't install it all this is what I do.

I go here https://www.firefox.com/en-US/channel/desktop/?redirect_source=mozilla-org&utm_source=blog.nightly.mozilla.org&utm_medium=referral&utm_campaign=blog-nav#nightly to download it then I do this on my Arch Linux cd ~/Downloads tar -xvf firefox-147.0a1.en-US.linux-x86_64.tar.xz sudo mv firefox /opt/firefox-nightly sudo ln -sf /opt/firefox-nightly/firefox /usr/local/bin/firefox-nightly sudo nano /usr/share/applications/firefox-nightly.desktop [Desktop Entry] Name=Firefox Nightly Comment=Browse the Web with Firefox Nightly Exec=/opt/firefox-nightly/firefox %u Icon=/opt/firefox-nightly/browser/chrome/icons/default/default128.png Terminal=false Type=Application Categories=Network;WebBrowser; StartupWMClass=Firefox
