Hi lwbt
Thanks for taking the time to report this bug 👍

I agree that the progressbar isn't visible in your screenshot, but sadly this is a result of missing GTK support in Firefox.
I'm not sure what options we have here - the best solution would definitely be for Firefox to add full GTK support.

We could consider to remove the firefox "blue text" modification and try to notify firefox Devs again to "suck up" the correct GtkTextView.selection styling + GtkEntry.selection styling
@clobrano opinions?
Personally I tried it in that bugzilla but that website is an absolute nightmare

[Feichtmeier]

So I could make the accent color orange again (including text, until they fixed that):

However,... this would not make the progressbar more visible on the selected row.

Same issue with adwaita gtk theme

So let's open a bug on firefox bugzilla and close this
