Problem : Just an hour ago I was browsing a web page and noticed that a few stray
pixels were showing up, then going away or moving sort of in a confetti
effect. When I scroll it gets worse and the pixels pile up and sometimes
slow down the entire browser. I cleared my cache and updated Firefox
and all my add-ons, restarted the browser, and even made sure it wasn't
my monitor by watching my desktop, opening other programs, and even
checking in other browsers. Only Firefox is causing this problem. It's
really annoying. Is there any way to fix this?
Solution :
1) Update your video card with the latest drivers.
OR
2) Try disabling graphics hardware acceleration in Firefox. Since this feature was
added to Firefox, it has gradually improved, but there still are a few
glitches.
You might need to restart Firefox in order for this to take
effect, so save all work first (e.g., mail you are composing, online
documents you're editing, etc.).
Then perform these steps:
- Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
- In the Firefox options window click the Advanced tab, then select "General".
- In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
- Now, restart Firefox and see if the problems persist
