That's very strange. Two questions:
1. Before step 1, were any web browsers pinned? Or no?
2. What's set as the default browser in System Settings > Default Applications?

Yes, I believe both Chromium and Firefox were pinned.

That'd be Chromium. 

This issue has come and gone so hard to debug - just today Firefox was replaced with Chromium then I removed it and added Firefox back - so far it has stayed that way. The only thing I can think of is I go back and forth between Arch system KDE and daily recompiled one using kde-builder installed in my home dir.

The web browser entry on there is special, it actually tracks the default browser. When that changes, the icon changes too.

If you remove that entry and pin Firefox or Chromium specifically, it will be the exact app, not "whatever is the default web browser".

So it's possible what's happening is that the default browser was actually changing somehow.

If that's not it, I'm at a loss and I think you might need to do more debugging. If you're  compiling everything with kde-builder, you're a fairly advanced person, and can check out what actual files on disk these apps point to. Looking at whether ~/.config/mimeapps.list changes on boot would be nice as well.

I double checked that I was pinning the specific browser from Task manager but it is possible the swaparoo was still happening due to change in the default browser - I have now explicitly set Firefox as the default and the issue has not reoccurred - not sure if something fixed it or was just a one off - either way closing it since I can't reproduce it anymore. Thanks!
