I am trying to modify the Preferences in the About.config settings, but I can not get into "about.config" in either normal Firefox mode or in Safe Mode Firefox.

For some weird reason, the "about:config" is now working. I tried closing and reopening Firefox numerous times, but About:config refused to work. Now after posting my problem with Mozilla Support, I went back into Firefox and was able to open About:config. Sorry about that.

I am typing ABOUT:CONFIG in that exact way. Is that not correct or should it be ABOUT CONFIG ? In the search (Location Bar) and I keep getting the message "there is no such website."
