Top bar fades from dark blue bar to light blue and I can no longer enter text until I click the mouse again.
> Top bar fades from dark blue bar to light blue
I’m sorry, I don’t know what this means.
1. What operating system?
2. What version of FireFox?
Usually that means that firefox memory usage has gone very high, probably due to a memory leak from one of your addons/plugins and you should restart firefox fairly frequently to get around this. You could try using something like Memory Restart to inform you when memory usage has gone too high and restart firefox. I’ve turned off the automatic restart option, and just use it to inform me of the memory usage.
Ah, you mean for some reason the app that is open somehow is no longer the active one? (on top)
yes, that is strange
