Firefox window turned full white, glitches or not responding.

With my new PC, Firefox is crashing very often. I’m finding myself in front of a not responding browser or just a fully white window. In some cases the web-page elements became full black or there are some graphical glitches (in text, images and videos). The solution was to minimize/maximize and wait for some time, change the focus to other app, move one tab to a new window or simply scroll up or down.

If you format your drive in FAT32, you will face all limitations of this old protocol (e.g. max file-size of 4GB) … if NTFS you will get all the Windows options available but will be read-only for Mac… if you format it in Mac OS Extended you will not be able to use it in Windows.

How to add your mouse device to PC and Mac (e.g. Microsoft Designer Bluetooth Mouse)

I recently bought a new Bluetooth mouse for my laptop… a Microsoft Designer Bluetooth Mouse. It’s a very beautiful mouse with a very good quality.

This mouse is very easy to connect to your Windows or macOS device. Read More
