Opera crashes when trying to set itself as the default browser on Fedora 44 KDE (Flatpak)

Parzival-1507 — Invalid Date

I recently switched to Fedora 44 KDE Plasma (fresh installation).

After installing all system updates, I installed the Flatpak version of Opera from KDE Discover (version 133.0.5932.60).

Opera launches normally and the first-run setup works fine until I click "Yes, set as default browser". As soon as I click that button, Opera immediately crashes every time.

The browser works normally otherwise; the crash only occurs when Opera tries to register itself as the default browser.

I've reproduced the issue multiple times on a completely fresh installation.

The desktop notification reports:

The command /app/opera/opera (Part of Opera) encountered a fatal error and terminated.
Signal: 5 (TRAP)

Opera 133.0.5932.24 crashes in a loop on startup

RiXiR — Invalid Date

Yep I had the same issue and I just uninstalled Opera and Re-installed it and it worked. I tried just re-installing the browser without wiping data and without uninstalling and nothing was working so I just went nuclear and wiped everything. Now it is working again.

Ubuntu: starting Opera fails

simroux — Invalid Date

Just to add to the list: I saw the same error with "chrome/browser/process_singleton_posix" when updating to 125.0.5729.12 on Ubuntu. I "fixed" it based on @zibi1981 suggestion above, as follows:

opera --ozone-platform=x11

From my crude understanding, it would again point to wayland vs x11 issue, but anyway, just sharing in case someone else ends up here after seeing opera crash on startup in Ubuntu.

Hi, i use Opera for work. In the last couple of days i can't even open the browser because it will just crash, open again on its own just to crash again for about 3/4 times. I've tried uninstalling and installing Opera again but it's still not it. What can i do to fix it?

Opera (profile, session) semi-broken after crashes

@steaua10 said in Opera (profile, session) semi-broken after crashes:

Is there a way to fix this issue?

If you think it's a session issue, you can close Opera and delete the "Sessions" folder in the profile folder to start with a fresh session. You'll lose all your tabs though, but that might fix it.

If you want to save your tabs, right-click on a tab, goto "save" and choose "all tabs to a speed dial folder". Then, with the new session, right-click that folder and choose "open all in tabs". You'd have to do that for each workspace too if you're using more than the default one.

@sushiking145 "for some reason" would generally be because the file is too big. Cut off the other parts of your images and then they should work.

Printing crashes the browser

frangershwing — Invalid Date

@miky666 I have the same problem and I'm using Firefox too to print web pages in pdf. The problem of printing pages in Opera came out of nowhere, one day it was working and next day it stopped and have not been working for a couple of weeks now.
I guess the too frequent updates of Opera are part of the cause of the problem with glitched printing. I can do downloads normally, including pictures from websites but cannot download the entire page

Crash issues Windows 10

burnout426 — Invalid Date

If you uninstall Opera, does explorer still freeze? If not, then yes, it's totally possible that Opera could be interfering in some way. But, it doesn't seem too likely.

@Mozza7 said in Crash issues Windows 10:

I recently reinstalled win10 entirely.

If you haven't gotten too far in setting everything back up yet, consider reinstalling again just to rule out issues with the Windows 10 installation.
