how can I delete tech-connect.biz as my firefox homepage?

Hi, sorry to hear you are having a problem; please try working through https://malwaretips.com/blogs/remove-tech-connect-biz/ by Malware Tips. '''Note that not all removal programs will detect all malware, so you may need to run several or all of them.''' You can also check your Firefox Desktop shortcut for corruption: Right click on it > Properties, and in Target, make sure there is no sign of the malware. If there is, delete that part of it. Or if it's easier, you can just delete and recreate a new shortcut. After removal you may need to reset your home page and search, which you can do by running the add-on [https://addons.mozilla.org/en-US/firefox/addon/searchreset/ SearchReset.] ''If your question is resolved by this or another answer, please take a minute to let us know.
