How completely remove incredibar extension

First of all read this arcticle:
"My Start Incredibar" remove manual for Firefox
Quote:
"If you did all those steps and still have the Incredibar in Firefox, then here is a Complete Removal Guide:
A. Removing All Regenerating Scripts of Incredibar

1. Open Your Profile Locations:

• "C:\Users\{USERNAME}\AppData\Roaming\Mozilla\Firefox\Profiles\{NAME}.default\

1. Search in the Search Bar "PREFS"
2. Open all files found in Notepad++
3. You will find a Line at the END of each file:
4. user_pref("browser.newtab.url", "http://mystart.incredibar.com/...")
5. Remove That Line or you can just use the Replace Function to replace the whole line in all of the Opened Files with a Blank Space
6. Save and Restart Firefox
7. Go To about:config and write "MyStart", right click to the result "browser.newtab.url" and click RESET
8. Write in the search bar "Incredibar" and press Enter
9. Remove all Entries by clicking them and choosing Delete

2. Click Edit>Find and Write "Incredibar"
3. Delete all Relevant Keys when found

C. Scanning For More Checks

1. Download "Spybot: Search and Destroy"
2. Install it and Update
3. Click Search and let it finish
4. If there are any Results select to Clean them

After all these Steps Restart your Computer"

If it doesn't helps you (like me), you should find "Profile" folder of Firefox:

How find 'Profile' folder of Firefox
1. Open 'Profile' folder.
2. Find all text files (.js scripts) with word 'incredibar'  inside
3. With notepad++ or another text editor manually remove in each file mention about 'incredibar'.
Attention: be carefull You should create backup of 'Profile' folder before making any changes to it.

P.S. Kaspersky 2012 do not blocks this nasty hijacker.
