Google Web Accelerator is a web accelerator produced by Google. It uses client software installed on the user's computer, as well as data caching on Google's servers, to speed up page load times by means of data compression, prefetching of content, and sharing cached data between users. The beta, released on May 4, 2005, works with Mozilla Firefox 1.0+ and Internet Explorer 5.5+ on Windows 2000 SP3+, Windows XP, Windows Server 2003, and Windows Vista machines.Google Web Accelerator sends requests for web pages, except for secure web pages (HTTPS), to Google, which logs these requests. Some web pages may embed personal information in these page requests.
Google receives and temporarily caches cookie data that your computer sends with webpage requests in order to improve performance.
In order to speed up delivery of content, Google Web Accelerator may retrieve webpage content that you did not request, and store it in your Google Web Accelerator cache.
Bugs and problems
It has been discovered that Google Web Accelerator has a tendency to prevent YouTube videos from playing, with the message in the YouTube video player, "We're sorry, this video is no longer available." By simply turning off Google Web Accelerator, the user should be able to play YouTube videos again without a problem. Users can also add .cache.googlevideo.com into the "Don't Accelerate These Sites" section in the preferences panel.
As of September 2008, the Google Web Accelerator is not compatible with Firefox 3.0.
Google Web Accelerator is currently (as of early November 2008) not available for download directly from the Google site, but it is still availible on download.com
