This article will help you remove third-party toolbars like Ask, searchqu, MyStart, incredibar, seeearch, somoto, sweetim, uTorrent, and others from Firefox and restore your default home page, New tab page and search settings. For help removing the Babylon toolbar, see How to remove the Babylon toolbar, home page and search engine.
Toolbars from third-party software providers can change your search, New Tab and home page settings or cause other problems with Firefox. These toolbars can get added to Firefox when you visit a website and click on an "Install" link, when you download and run a toolbar installer, or when you install software that includes a Firefox toolbar. Be careful when installing or updating other applications and make sure you deselect any options for toolbars or other bundled software that you don't want.
Also, some software providers offer their own version of Firefox that includes a toolbar and other customizations (for instance, Mozilla Firefox® optimized for Yahoo!) so always make sure you download Firefox from the Firefox download page.
In most cases, third-party toolbars can be uninstalled from Firefox Add-ons Manager Extensions list, as follows:
Click the menu button and choose Add-ons. The Add-ons Manager tab will open.
If you can't remove the toolbar from the Add-ons Manager, use the "Disable" option as a workaround, or see the Cannot remove an add-on (extension or theme) article for other solutions.
You may need to reset your Firefox search preferences and restore the default New Tab page, home page and search engine after removing the toolbar. A simple way to do that is with the SearchReset add-on.
