- Let's try something different. There's two different settings I want you to mess with. First is the 'Hardware Acceleration' for Adobe Flash.
1) Go to the web site that has the video/flash that's giving you problems and right-click on it. You should see the following pop-up menu:
2) Click 'Settings'
3) Click the box 'Enable Hardware Acceleration' to clear it then click 'Close'.
4) Restart Waterfox and see if this fixes the problem. If not, go to step 5.
5) It didn't work! Let's try disabling 'Hardware Acceleration' for Waterfox. Go to your options menu in Waterfox and click 'Use hardware acceleration when available' to clear the box then click 'Ok' at the bottom.
6) Restart Waterfox and see if this fixes the problem.
Adobe Flash FAQ:
What are display settings?
Display settings allow you to use hardware-accelerated scaling to improve the speed of playback in Flash Player.
What happens if I do nothing?
By default, Enable Hardware Acceleration is selected to improve the quality of playback in Flash Player, particularly the performance of full-screen playback.
What is hardware-accelerated scaling?
Although Flash Player can display high-quality video and images by itself, hardware-accelerated scaling uses the video or graphics card on your computer to display images and video more clearly and quickly than Flash Player can on its own.
Will hardware-accelerated scaling work on all computers?
For hardware-accelerated scaling to work, you need Microsoft DirectX 9 with VRAM 128MB for Windows and OpenGL for Apple Macintosh, Mac OS X v10.2 or higher. There might be compatibility issues with older hardware and drivers. (See Flash Player system requirements.) With older versions of Flash Player, you should not see dramatic changes as the player reverts from hardware-accelerated scaling back to software scaling.
If I have display problems with Flash Player, what should I do?
If you have display problems with Flash Player, such as poor picture quality or slow display times, deselect Enable Hardware Acceleration in the Display panel. This should eliminate hardware or driver compatibility problems with Flash Player. Flash Player then uses software to scale and display the content.
Waterfox/Firefox:Use hardware acceleration when available
: Firefox can use your computer's graphics processor to display some pages with video and animation. This makes Firefox faster since your computer's graphics processor is much better than your computer's main processor at displaying these types of things. This box is checked by default but the feature isn't available for all graphics processors. Firefox will enable it when possible. If you change this setting you must restart Firefox.Edited by djkilla - 4/4/12 at 8:34am
