I found this tut, its useful for people who want to download files from Rapidshare quickly:
"To get the counter down to 0 quickly in rapidshare all you have to do is:
1. Goto the page you want to download
2. Select FREE button
3. In the address bar put the following: jalert(c=0)
4. Click OK
5. Click OK to the pop-up box
6. Enter the captcha
7. Download Your File
You only save a couple minutes but when you need something fast, it helps
"
Enjoy
