Fix: Blurry text while scrolling on Firefox

One day I have noticed that some text gets blurry while scrolling on Firefox. I have managed to fix this by disabling a feature in Firefox.

Open Firefox
Open a new tab
Enter about:config in the address bar
Click on the “I’ll be careful I Promise” button
Find gfx.content.azure.enabled
Double click on it to set it as false (963)
