Your Firefox might have been invaded by unwanted add-ons and settings. A "quick fix" is to use the Refresh feature, but if you have numerous add-ons, then it's time-consuming to set those up again. Here's the article if you're interested: [[Refresh Firefox - reset add-ons and settings]]. If you want to dig around a bit first, I suggest starting here: (1) Open the Windows '''Control Panel''', Uninstall a Program. After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help surface undisclosed bundle items from Ask or affiliated entities that snuck in with some software you agreed to install. ''Be suspicious of everything you do not recognize/remember, as malware often uses important or innocent sounding names to discourage you from removing it.'' 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 Windows "Run" dialog, type or paste <br><code>firefox.exe "about:addons"</code> 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. ''Bear in mind that all extensions are optional, none come with Firefox, and you can learn more about them by checking their reviews on the Add-ons site.'' 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) Repair settings You can restore the built-in home page, default search engine, and standard new tab page using this extension: https://addons.mozilla.org/firefox/addon/searchreset/ If you prefer to change them manually, these articles cover the home page and search engine: * [[Startup, home page, tabs, and download settings]] or [[How to set the home page]] * [[Use the search bar in Firefox]] The new tab page is a little more involved: (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button promising to be careful. (2) In the search box above the list, type or paste '''newtab''' and pause while the list is filtered (3) Double-click the '''browser.newtab.url''' preference and enter your preferred page: * ''Page thumbnails (default)'' => about:newtab * ''Blank tab'' => about:blank * ''Built-in Firefox home page'' => about:home * ''Any other page'' => full URL to the page Press Ctrl+t to open a new tab and verify that it worked.
