I’ve been running ubuntu I think since Focal Fossa. I often copy paste terminal output into the firefox url bar to search for more context about the output.
Often a process will output in the format ^\S+:\s.* … like "Error: ". Firefox was interpreting this as a protocol handler and would ask me what program I wanted to open the non-existent protocol with, disrupting my workflow and annoying the heck out of me.
Someone from mozilla suggested I check if their version did the same thing so I removed the snap and installed firefox from their apt repo. They were right, I couldn’t reproduce the issue in their package.
Now I am stuck figuring out how to restore my firefox profile from the snap .mozilla directory backup I made.
I honestly thought the snap hate was overdone but I must admit this was a disappointing experience to say the least. Also it’s nice your forum has a dark mode now but please consider implementing the Sec-CH-Prefers-Color-Scheme response headers and functionality to auto select theme based on the client’s requested colour scheme.
