You probably have tried some different troubleshooting steps, but just in case: When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site. (1) Bypass Firefox's Cache Use Ctrl+Shift+r to reload the page fresh from the server. Alternately, you also can clear Firefox's cache completely using: "3-bar" menu button (or Tools menu) > Options > Advanced On the Network mini-tab > Cached Web Content : "Clear Now" If you have a large hard drive, this might take a few minutes. (2) Remove the site's cookies (save any pending work first). While viewing a page on the site: * right-click and choose View Page Info > Security > "View Cookies" * Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies" In the dialog that opens, you can remove the site's cookies individually. ''If you cannot open the site at all, you can open the dialog on this site, then change the domain in the search box at the top to fanfiction.net'' Then try reloading the page. Does that help? ---- To rule out extensions as a possible culprit, could you try the site in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions, some advanced features, and some custom settings. More info: [[Troubleshoot Firefox issues using Safe Mode]]. You can restart Firefox in Safe Mode using either * "3-bar" menu button > "?" button > Restart with Add-ons Disabled * (menu bar) Help menu > Restart with Add-ons Disabled Note: Flash and other plugins still run After Firefox closes, a small dialog should appear: click "Start in Safe Mode" (''not'' Reset) Any difference?
