How to Uninstall StumbleUpon

StumbleUpon is an internet discovery engine that allows users to submit new and interesting Web pages to the StumbleUpon database. StumbleUpon then sends these webpages to other users signed up to the service. In turn, those users can view and rate the content. StumbleUpon offers a browser toolbar for both Mozilla Firefox and Internet Explorer that allows you to easily submit sites that you find to StumbleUpon. If you do not like the toolbar or if it causes your browser to crash or slow down, you can uninstall it.

Instructions

Firefox

1. Open your Firefox browser and click "Tools" in the file menu.

2. Scroll down and select "Add-ons." A new window displaying all installed add-ons will appear.

3. Click the "Extensions" selection at the top of the Add-ons window. Scroll through your list of installed add-ons and find "StumbleUpon."

4. Click "Uninstall" next to "StumbleUpon." A confirmation dialog box will appear.

5. Click "Uninstall" on the confirmation dialog box. The browser will uninstall the toolbar and a yellow bar will appear in the Add-ons window that says "Restart Firefox to complete your changes."

6. Click the "Restart Firefox" button on the right side of the yellow bar to restart the browser without the StumbleUpon toolbar.
