File hosts obviously are interested that users stay on their websites for as long as possible to earn from advertisements, make the site more attractive to advertisers and to sell their premium accounts to users who are not patient enough to wait. Nearly every file hosting site uses times, bandwidth limitations and other means to achieve these goals.

Extension developers on the other hand have to cope with ever changing scripts on the sites. File hosts change technicalities regularly to break extensions and other tools that offer faster downloads from their servers.

It will therefor be only a matter of time until the Google Chrome extension Megaupload Instant Download Helper needs to be updated. The extension for now offers to speed up downloads at the popular file hosting site Megaupload by bypassing the wait time limit that is imposed on free users.

The functionality of the website is not changed, which means that the regular download button is displayed once the countdown has reached zero. That may be helpful if the extension fails to display the download directly.

Megaupload Instant Download Helper can be installed directly from the Google Chrome Extensions gallery.

The extension tries to start downloads on Megaupload download pages automatically. Users who want to download files see the save as dialog directly even if the time is still counting down.

Alternatives are available for other browsers. Opera users may want to take a closer look at the Opera Download Helper extension, Firefox users at the userscripts Megaupload Automatic Downloader or Megaupload Automatizador Plus!.

Megaupload is a file hosting service on the Internet that is displaying a captcha before the download link of a file will be shown on their website. The captcha is probably one of the easiest to recognize and fill out, pretty useless from the standpoint of defeating bots and annoying to users who download files from Megaupload regularly.

Megaupload auto-fill captcha is a Greasemonkey script for Mozille Firefox (and other compatible browsers) that will automatically fill out and send the captcha on Megaupload. This essentially means that the user does not have to enter the captcha nor click on a button to send it to the Megaupload server.

It practically feels as if there was not a captcha on Megaupload at all. A short explanation of Greasemonkey. Greasemonkey is a Firefox extension that can be installed just like any other extension in Firefox. Once the extension is installed it is possible to add so called userscripts to the web browser.

Those scripts are coded in JavaScript and change the behavior and look and feel of websites automatically.
