Hello Bob, try disabling graphics hardware acceleration.

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:

1. Open Firefox Options window as follows, click the menu button and select Options .
2. In the Firefox Options window, click the Advanced tab, then select General.
3. In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
4. Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

• Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

• Upgrade your graphics drivers to use hardware acceleration and WebGL

Did this fix your problems? Please report back to us!

Thank you.

Thanks, but no change. I did not think there would be.

SOMETHING has changed from 33 to 36. Not sure which version changed as I never tried 34 or 35, but the colors are different in 36 than any other browser or older Firefox. Very noticeable.

Other ideas please? There must be something causing this. It is not my computer as 33 still looks as expected.

Thanks!

Can you attach a screenshot?

• Use a compressed image type like PNG or JPG to save the screenshot
• Make sure that you do not exceed the maximum size of 1 MB

This can be caused by a problem with the color profile for your display monitor or color profiles embedded in images. Try to disable color management to test if it is caused by a problem with color management. You can set the gfx.color_management.mode pref to 0 on the about:config page to disable Color Management. You need to close and restart Firefox to make the change effective. See:

• http://kb.mozillazine.org/gfx.color_management.mode

We found it at the same time :)

Somehow FF was using a color profile that no longer existed on my computer. Did not affect 28 or 33 for some reason, but did 36! Changing to a know monitor profile fixed the issue.

Thanks!
