Hi, try turning off 'Enhanced Tracking Protection' for that site by clicking the shield icon at the left-hand end of the address bar while the page is loaded - [[Enhanced Tracking Protection in Firefox for desktop]]. If that doesn't help, disable any ad blocker you may be using then reload the site. ------------------- Hold down the Shift key when you start Firefox to start in Safe Mode. More - [[Troubleshoot Firefox issues using Safe Mode]]. If it works in Safe Mode, disable any theme or extensions you have - 3-bar menu > Add-ons > Themes/Extensions, then restart Firefox; now if it's still OK, re-enable them one by one until you find the culprit. You may need to restart Firefox after enabling some extensions. Note: If you use '''userChrome.css''' or '''userContent.css''' - you don't have it if you don't know what it is, this is also disabled in Safe Mode, so should be regarded as an additional - if unlikely suspect, and can be disabled to test by placing '''/*''' before, and '''*/''' after the file in the chrome folder, then restarting Firefox. ---------------- Try deleting ALL references to Disqus. To do that, open the 3-bar menu > Library > History, then click the Show All History link at the bottom of the list to open the History-library window. Search for Disqus by typing it into the Search History field in the top-right corner. Now in the search results, right-click on Disqus and select Forget About This Site. '''(Browsing and download history, cookies, cache, active logins, passwords, saved form data, exceptions for cookies, images and pop-ups for that site will be removed).''' Give it a few minutes to complete the deletion, then try the site (not from an old bookmark) again. More - [[Delete browsing, search and download history on Firefox]].
