Though I do not have any problems with tiny arrows on Twitter/Firefox3 Some of my friends complain that they see blah blah instead of the right signs. And when clicked they get errors. Must be a problem with unicode support I guess & it will be a major drawback for the tinyarrows :(
I just twittered via twitterfox. I checked on my Twitter page & it shows up well for me. But a friend using Fx3 on window$ just complained there are problems viewing it. WC.
Thanks a lot for the clarification. If it's not a hassle, can you ask them how they read Twitter? Did they visit the website or get through a different reader?
