I had the same problem yesterday. Once I restarted Firefox, it seemed to clear it up. Maybe it's a glitch in Firefox 1.5 causing it? I dunno, just a thought.
Someone in your IP range prolly did something to make it get blocked by Google. Maybe not on purpose, but.. ehh, it happens. It should go away after a little bit.
I can't believe that we're having a discussion about Google's goof-ups! You guys are gonna love this... Check out the attached image... it's a screenshot of the error I received on the 25th of June, '05, when I asked Google to define "ass" just as a silly experiment with the search field on my Google bar. Notice that the messege at the bottom reads, "...please mail error@google.com and mention this error and the query that caused it." Now how am I supposed to explain to them why I needed a definition for "ass"?! :dunno:
lol. Thats quite a good one. Ah, it is a Firefox error hey. Thats good to know. Don't like the thought of being on Google's bad side, they give me ad money lol
