SUMMARY I didn't experience this when opening from Dolphin, but if I use Firefox to open up files, they usually open up at Firefox itself. STEPS TO REPRODUCE 1. Save an image with Firefox 2. Open up an image OBSERVED RESULT Image opens up in Firefox as a separate Window EXPECTED RESULT Opens up preferred image viewer (in my case Gwenview) SOFTWARE/OS VERSIONS Operating System: Kubuntu 20.04 KDE Plasma Version: 5.18.3 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.5 Kernel Version: 5.4.0-21-generic OS Type: 64-bit Processors: 4 × Intel® Core™ i5-6500 CPU @ 3.20GHz Memory: 15.6 GiB of RAM ADDITIONAL INFORMATION I set the defaults using Dolphin, which is why I created the bug report under Dolphin
Sounds like a bug in Firefox or how it's configured. Can you check in Firefox > Hamburger menu > Preferences > Applications > Search for "image"?
If you run `xdg-mime query default image/jpeg` in terminal (e.g. Konsole), what does it return?

It uses "Always Ask". If I open the drop down, the options were "System Handler" and "Other".

It returns org.kde.gwenview.desktop, but I'm assuming it's because I changed the mimeinfo.cache manually.
> if I use Firefox to open up files Does that mean after downloading an image file in Firefox, you click on (open) the file in Firefox's internal download manager and it opens in a new (separate) Firefox window/tab? (If you explicitly use CTRL-O (or File > Open...) in Firefox to open the image, then it will be displayed in Firefox, which is expected.) By the way, have you tried using a fresh Firefox profile (i.e. all Firefox settings reset to default, all extensions disabled) to see if the problem persists?
