I assume you're running Windows... Let's start with removing ShopAtHome software. This will take a few minutes, but it's very do-able. Here's my suggested procedure for tracking down and cleaning up '''bad add-ons'''. Sorry for the length -- it's not as bad as it sounds: (1) Open the Windows '''Control Panel''', Uninstall a Program (or on XP: Add/Remove Programs). After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help in smoking out undisclosed bundle items that snuck in with some software you agreed to install. Take out as much trash as possible here. (2) Open Firefox's '''Add-ons page''' using either: * Ctrl+Shift+a * "3-bar" menu button (or Tools menu) > Add-ons In the left column, click '''Plugins'''. Set nonessential and unrecognized plugins to "Never Activate". In the left column, click '''Extensions'''. Then, if in doubt, disable (or Remove, if possible) unrecognized and unwanted extensions. 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. Any improvement? (3) You can search for remaining issues with the '''scanning/cleaning tools''' listed in our support article: [[Troubleshoot Firefox issues caused by malware]]. These on-demand scanners are free and take considerable time to run. If they finish quickly and especially if they require payment, you may have a serious infection. I suggest the specialized forums listed in the article in that case. Success? And then last but not least, if you need help with your home page or new tab page, please let us know and we can post the steps for that.
