While I was typing the last post I made, FRD required a captcha. However, because I forgot to close it to the system tray after the last captcha prompt, instead of stealing focus to prompt me, it just popped up in the background BEHIND the full-screen Firefox Window I was using. Needless to say I had no clue it needed input. By the time I saw it, the time period had expired and I hit that "keep prompting the user for captchas until he hits escape, don't actually start the download" bug. I then had to track down download and restart it.
Could you please put in a feature to also play a sound whenever a captcha is required so I get an audio cue when it prompts me in the background BEHIND my current window? Many times that would be the only clue that I actually need to enter anything.
