I suspect an add-on from that site, or its software, changed your Firefox home page. To clear that up, please start by checking your add-ons. You can view, disable, and often remove unwanted or unknown extensions on the Add-ons page. Either: * Command+Shift+a (Windows: Ctrl+Shift+a) * "3-bar" menu button (or Tools menu) > Add-ons In the left column, click Extensions. Then cast a critical eye over the list on the right side. All extensions are optional. If in doubt, disable. Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step. Next, check whether your preferred home page has been replaced by a different one, and reselect the startup page you want. Either of these articles will help with that: * [[How to set the home page]] * [[Startup, home page, tabs, and download settings]] Can you get Firefox back to the way you like it?
