I'm currently using Firefox 4(.o.1). when i checked the add-ons manager, in the "extensions" tab, there are no extensions and it says here "you don't have any add-ons of this type installed". i've restarted the browser a few times and my laptop once, and no changes at all except for one lucky time when it seems normal. i don't know whether it is there but no one can see it or what. i've been using adblock plus and so far, i see no ads/popups.

Please do the following.

The URL to add in "keyword.URL" becomes a link in this post, so right click it and choose "Copy Link Location" to copy it to the Windows clipboard. Then hit CTRL+V to paste it. Saves you having to type the whole thing.

To reset your home page, do the following.

  • Go to the site you want to set as your homepage.

  • Click the orange Firefox button and go to Options | Options | General.

  • Make sure it says "Show My Homepage" in the first dropdown menu.

  • Click the button called "Use Current Pages" to set the homepage to the one you have on the screen.

After you complete the above steps, install this add-on to prevent another search engine from modifying your preferences: https://addons.mozilla.org/en-US/firefox/addon/browserprotect/

After you complete the above steps, open the "Add-ons" | "Extensions" menu again and remove SweetIM Toolbar if it's there.

Deleting the "extensions.sqlite" file in my profile folder http://kb.mozillazine.org/Profile_folder_-_Thunderbird fixed it — be sure to make a copy of the file beforehand.
