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.
Read the solution after the jump.
If you are having this same problem, first try updating the extension (for a new version might have been released that resolves this issue). If that doesn’t work, simply disable/uninstall the Delicious extension.
Update 1: I have started to use Delicious extension once more, and I am not facing this issue anymore. Thus, update to the latest version of Firefox (3.0.4 at the moment) and to the latest Delicious bookmarks extension (2.1.018 at the moment).
Update 2: As noted in the comments, AVG Safe Search has also been the source of the problem for some.
