OFten, when refreshing my Yahoo Mail and other random websites, I get the "Invalid URL" mesage. The error says "The requested URL "XXXXXXX", is invalid", however that is NOT the same URL in the address window. This happens mostly with Yahoo mail but also randomly with other websites.

URL of affected sites

http://us.mc371.mail.yahoo.com/mc....

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). 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. You can use "Disable all add-ons" on the Safe mode start window. You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")
