My favourite Firefox Add-ons

Everybody has their own set of favorite Add-ons. Here are mine:

• DownThemAll!:
• Advantages: 
• Way faster than the conventional download method.
• Allows pausing and resuming downloads.
• Works with Video DownloadHelper.
• Easy to use.
• What it does: Simultaneously makes 4 parallel connections to the download site quadrupling download speeds.
• Video DownloadHelper:
• Advantages:
• If you can watch a video, you can download it.
• You don't have to watch the entire video in order to download. Just start the video and the download link will be available - Good if you have a slow connection.
• You can close the video window after download begins.
• Have a slow connection? Frustrated with video lag? - Download the video and watch it later.
• Flashblock:
• Advantages:
• Blocks flash applications - They annoy me a lot.
• Helps if you have a slow connection.

I use DownloadHelper to download videos. DownThemAll works like a charm with it - now I can download videos in no time.
