Hello, Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: ''This will temporarily log you out of all sites you're logged in to.'' To clear cache and cookies do the following: #Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history. #Under "Time range to clear", select "Everything". #Now, click the arrow next to Details to toggle the Details list active. #From the details list, check ''Cache'' and ''Cookies'' and uncheck everything else. #Now click the ''Clear now'' button. Further information can be found in the [[Clear your cache, history and other personal information in Firefox]] article. You may also want to try troubleshooting in safe mode. * [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]

Is it only this website that Firefox has issues openning?<br> What programming language(s) does your Yahoo homepage use?

Worked! Thank you!
