Mozilla typing backwards Options

[Tomates]

so i just started getting this problem tonight for the first time. Only in
Firefox. Instead of the cursor (for the URL) remaining at the end of your text to
put the next letter you type at the end, the cursor automatically
moves to the beginning of the text and pushes the letters out so that
everything is backwards.

So heres an example of what im talking about

when i simple type out www.createblog.com
it looks like this on the mozilla moc.golbetaerc.www

so anyone know how i can fix this?

also this is only for the typing in on the browser/url
otherwise it types regularly on everything else
(tested on facebook)
