In Firefox browser only (NOT IE,) Yahoo Mail screen jumps up, then down 1 line every few seconds.
The following happens ONLY when I use Firefox. It does NOT happen when I use IE; and it happens ONLY in Yahoo Mail.
Whenever I'm in Yahoo Mail, my screen jumps 1 line--alternating up, then down--every 5-15 seconds. While composing e-mail, when I get ready to click on something or type something, the screen will jump up or down 1 line and cause me to click on something I don't want, or type something in the wrong place.
It's also extremely annoying to try to read mail.

Do you have the Yahoo! Toolbar?
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
- Don't make any changes on the Safe mode start window.
See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
- Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
- Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
>In Firefox 4 Safe mode also disables plugins (Tools > Add-ons > Plugins) and hardware acceleration (Tools > Options > Advanced > General)
Thanks, Cor-el for your help.
Firefox will not start in safe mode. And as of yesterday (11/14), Firefox will not start at all. Received Crash notice, sent crash report; then nothing when I double-click on firefox icon.
Today, I UNinstalled Firefox, then REinstalled. Still nothing when I double click on firefox icon.
No trouble with getting into IE. Must I switch???
