Problem:
There’s this annoying little bugger in Firefox, where, out of the blue and just so randomly, the address bar stops responding to the Enter key after you have entered the website’s URL!
No matter what you do: press Enter, Ctrl + Enter, click the (Go) Arrow button … Firefox would sit there idle, as if it’s ignoring the Enter key, while the cursor keeps on blinking in the address bar as it is.
