An external source changing the page shown when a new tab is opened.
I recently downloaded some freeware and, without permission, it installed some malware by the name of My Start by Incredibar that hijacked the home page, new tab page, default search engine, and other functions in Firefox.
The removal of the program itself was a simple task, as was disabling and uninstalling the addon it had installed in Firefox. I thought everything was back to normal, but when I went to open a new tab the My Start site appeared instead of the default blank page.
Will a reinstall without deleting user data solve this problem? I would rather not have to pull a full clean reinstall as I have a lot of addons with custom settings and logins.

Firefox needs to be closed when removing the item from Windows Control Panel. Did you remove both items?
After resetting the about:config "mystart" items, Firefox must be restarted for the items to disappear from about:config.
If you edit the user_pref items in prefs.js while Firefox is open and there are "mystart" or "incredibar" preferences in about:config, your changes in the prefs.js file will be overwritten.
Did you try the add-on that I suggested above? https://addons.mozilla.org/en-US/firefox/addon/searchreset/
You may need to reset Firefox to its default state and start over with a new profile. Read the following and all links in the following carefully for a full understanding of resetting Firefox. See - https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems

Yes, I have tried everything I know to remove all traces of the program from Firefox. I used Windows to get rid of the original program, and then went in and manually cleaned out the residual folders.
I have uninstalled the program and addon, cleaned my registry, flushed my DNS cache, blocked the incredibar domain from placing cookies through Firefox, went into the about:config menu and reset the browser.newtab.url to default setting, and I even went into prefs.js and manually deleted all the user_pref("extensions.incredibar.x" , x); enteries (that persisted after uninstallation of the addon). And still, when I restart Firefox and open a new tab, the My Start page is there.
I have looked for a solution to lock the preferences or block any changes to the about:config menu, but everything i have found is at least several Firefox versions out of date.I have tried everything I know to remove all traces of the program from Firefox.
It looks like other people on the page you posted are having the same problem with the persistent incredibar page appearing when they open a new tab.

Alright! I think you solved it - I didnt have all Firefox processes closed when I edited my prefs.js file.
I've restarted Firefox Several times and restarted my system and the solution seems to be perminant!
So, in conclusion for everyone who comes looking for an answer- follow all of the above directions if you haven't already, then close all Firefox processes and navigate to your prefs.js file, usually:
C:\Users\[your user name]\AppData\Roaming\Mozilla\Firefox\profiles\[your profile]\prefs.js
and delete all entries beginning with User_Pref("extensions.incredibar.
Save and close.
Thanks much!
Just looked, and the entries are still present in the prefs.js file, but have disappeared from the about:config menu and seem to be benign. Well, im back to normal now! Thanks again.
Did you check for the presence of a user.js file that might re-add the prefs on each start of Firefox?
Ah! I read through that article and incredibar had a generated a user.js file to reconstitute itself. Sneaky...
Thanks for your help!
You're welcome
