firefox problem

[neon]

I installed a new theme and it changed it like this..

I uninstalled firefox and re-installed and it's still the same
is there anyway to put default setting back on?

looks like a real mess - which theme was that?
check that you dont have 2 firefox process running in taskmanager (ctrl alt del)
back up your bookmarks
& passwords
then uninstall
then manually delete C/documents settings/user/application date /mozilla folder
and delete the firox folder in program files
then reinstall
