Browser and flatpaks randomly crashing

I have a laptop I’ve been running various Linux distributions on for the past 3 years. Currently on Fedora39 but I’ve had this issue on every distro I’ve run.

Randomly (usually after an extended time) I will have browser tabs or the entire browser crash. Gives me that “Gah your tab has crashed” error. Happens on Firefox, Brave, Vivaldi. Happens if I’m running flatpak or installed from repos. How can I view error logs and what would I be looking for? Or where would I go to post error logs for bug reports?

Same will happen (mostly with Bitwarden) with flatpaks randomly. I will just get a white / blank screen on the app. How can I view log/report?

The laptop in question is a Thinkpad E495 with 32gb ram.

You mentioned using a few distros before. Did this error occour already in the first days/ weeks of using the new install, or did it occour in the long term?

If that’s the case, consider switching to an image based (“immutable”) distro like Fedora Silverblue. Due to their image-based nature, they don’t have any package drift.

On a traditional system, the configuration slowly changes over time, due to updates and new installs, and therefore bugs may occur that only you have, so they’re not fixable.

An immutable system is reproducible and should contain less bugs.
Maybe try that?


Have you deleted Firefox, removed all data and reinstalled it? Probably won’t help, but it might?

Does it only happen on this device, or on others too? Maybe the RAM is faulty. Do you also have other freezes and crashes, like when you’re gaming?
I had similar issues when I had a damaged/ misconfigured RAM.
Or your storage (SSD?) is faulty?


Is it only on Flatpaks, or on native packages too?
A small bandaid workaround would be to just stop using Flatpaks and use Distrobox containers. They work fine too.


But I would try to fix the underlying issue first if I were you. I think it’s a hardware problem.

Run a full memtest on your RAM. Very likely you may have developed a few bad areas. Take pics if it finds bad zones, you can use the addresses to tell the kernel to avoid them.
