Hi,

You may also have to Remove the Extension in Firefox Tools (Alt + T) > Add-ons (it could be another name). You can also check the Windows Control Panel > Programs and Features for unfamiliar programs, search the name on the web to check if it's related to yandex and uninstall it.

Uninstalling Toolbars

Uninstalling Add-ons

Alternatively you can also Reset Firefox and start afresh.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

1. Go to Firefox > Help > Troubleshooting Information.
2. Click the "Reset Firefox" button.
3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

Nope, restarted firefox, nothing helped and how I sad there is no toolbar to unistall. Even searched for that website cookies and deleted them, but it didn't help at all.

Does anything come up with a search on the about:config page?

Nothing similar to the page in about:config

You can check for problems with the places.sqlite database file in the Firefox Profile Folder.
