Please update to Firefox 21 Update Firefox to the latest release, then Reset Firefox Refresh Firefox - reset add-ons and settings

Thanks for the reply, Tylerdownder. In doing so I fear that many extensions that are nearly critical to me will be incompatible. In checking, some extensions go through v. 19.* only.

Went into about:config and found the New Tab is actually the Mozilla Plugin Checker page. Deleted the URL in about:config, but to no avail. Because this is a Mozilla generated tab, is there a way to rid myself of the Plugin checker? Just a little paranoid about losing those extensions that I use every single day.

If you have extensions that are working in Firefox 11, they will work in Firefox 21 (because Firefox now, since 10, defaults all to compatible). Plus you don't want to be on older versions due to security risks. Update to Firefox 21 ASAP, then update your extensions and plugins.

Thanks, Tylerdownder. Updated to 21 and the tab is gone and all the extensions work. Unfortunately, can't say the same about any of the Themes I used, but that was secondary to extensions.

Thanks for your help. Greatly appreciated!

You can check the home page setting.

Firefox supports multiple home pages separated by '|' symbols, so make sure that you do not have a trailing '|'.

• Tools > Options > General > Startup: Home page
• https://support.mozilla.org/kb/How+to+set+the+home+page

If you do not keep changes after a restart then see:

Thanks for your reply, cor-el. I'd checked the homepage setting before I decided to update and only the Yahoo homepage was present under those options settings. Thanks again!

You can also check the target line in the Properties via the right-click context menu of the Firefox desktop shortcut.
