I'm having a very common problem, but nothing is fixing it.

First of pls note these only apply if your on a PC.

If this problem started recently think back of how long ago. If it was after update could be that it may have something to do with the direct x. Make sure it's up to date, iof so install and reinstall it.

Is your graphics card / monitor up to date on it's drivers?


Try testing your monitor on something else example. Does this only happen with FF or does it happen with other programs? If it does it could be a monitor issue as well. Try using it on an external device like a gaming console. If it happens there it could be do to the monitors refresh rate may have changed, or it's getting old.

If non of the above apply or work you could try doing a system restoration to a point were it did work. See if that helps. If everything else fails you can try perhaps you may need to either upgrade your graphics card or try lowering the specs to a lower setting. Try running the bench mark for a recommend setting. Hope this helps.
