I have removed "mystart.incredibar" virus by Reset of all entries related to it in about:config page and then start Firefox in safe mode. After restarting Firefox, all reset values again highlighted and displays as user define. How do I permanently delete these entries related to "mystart.incredibar"?

razakm, I have a idea that there is a file called user.js in your Firefox folder. If you can delete this file, I believe the entries (or preferences as we call them) will stop coming back after you reset them.

To find the user.js file:
Go to Firefox button > Help > Troubleshooting Information then click on the Show Folder button.

Once the window for the profile folder opens, close Firefox. Then look for a file named user.js in that folder and delete it. Open Firefox again & check to see if the entries are there. If they are, right-click and Reset them again. Now restart Firefox and see if the problem stays gone.

If you could do me a favor though, before deleting user.js. Could you make a copy of it to your desktop & email it to me @ mozsupport@gmail.com ? I want to see how many entries it is making & see if it is doing anything else bad. Thanks.

See this Google search for help. Too damn many circular discussions about what works and what doesn't.

Basically, you need to figure out what was installed on that PC which still remains, and is resetting those prefs in Firefox - probably resetting them every time you launch Firefox. You need to get rid of it completely.

Hi, the hint with user_pref("browser.newtab.url", ""); in about:config was very helpful.

but evertime i opened Firefox the entry were changed. I monitored the prefs.js with notepad++ (for alert on change) everytime i open Firefox the file was changed (not only loaded) few hours later... the entry for newtab were attatched to an existing extension.

1. rename extensions folder in default profile 2. create anew empty extensions 3. move one extension to the new folder 4. open firefox 5. open new tab 6. repeat step 3-4 till the wrong incredibar appear 7. goto the last moved extension folder "extension-folder"\defaults\preferences 8. open prefs.js and delete the row withe the user_pref
