Rubber duck debugging often helps.

I don’t like being on this picture.

That boils down to maps. With a few helper functions it’s not a big deal. I can’t remember when I needed to unmarshal JSON into map last time, tho.

I’ve already made this choice. Switched from C++ to Go, and now I never want to touch another language at all. Since I’m not writing kernels or embedded, Go is pretty fast for everything else. Not very popular in gamedev, but that’s just a lack of 3rd party libs, specifically native graphics support.

As for other languages, I can’t justify unnecessary complexity that is generally welcome by those language communities. Go is straight simple yet powerful, and I admire that.

Which adds up to 180%. And that is all you need to know about deadlines.

It works fine with my Cinnamon window manager. So the bug could be in Firefox, in your WM, in both, or more likely in the integration of two, as a side effect, which why I’ve said “on the edge”. It’s nearly impossible to test your software with every combination of a system. So the solution here to file an issue both for WM and Firefox and hope someone from either communities will solve it. Or just get another browser or WM.

Look like a bug on the edge of WM/App

I wonder if you deem Firefox buggy or having not enough features?

Using Firefox since it came out and never experienced any troubles.
