Everytime I am on any website, my text completely distorts, or a big white square goes across the screen. I have to highlight the text to show it.

It is even happening right now as I am typing this. I am unable to read anything on the top tabs and my text in the search bar is blurred. I tried the accelration technique within options, no luck. I have also tried other techniques written by users but nothing is happening. Trying to read websites is becoming very hard and I have to keep highlighted the words or pictures to show them.

Did this just start suddenly out of the blue, or can you associate with any changes (e.g., software updates)?

Could you try Firefox's Safe Mode? That's a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: Diagnose Firefox issues using Troubleshoot Mode.

You can restart Firefox in Safe Mode using

Help > Restart with Add-ons Disabled

In the dialog, click "Start in Safe Mode" (not Reset)

Any difference?

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.


It is possible that there is a problem with the font.


Try to set the gfx.content.azure.enabled pref to false or if this didn't help disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that has effect.

Yes this seemed to work, but what happens now. Do I need to remain in safe mode everytime i browse?
