Recently, I had the latest Firefox 40.0 version installed on my computer.
A strange problem had then popped up on my HP PC: When I started entering letters in the "Search or enter address" window of Firefox, the first few letters appeared extremely faint and thus unreadable, though they reappeared when I kept typing the search letters.
I thought of replacing Firefox 40 by its previous version 39 as a possible remedy. The remedy worked!
I am entering this post only for the awareness of other Firefox users as to what worked for me.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
