TestAssist

Test Assist is a helpful Firefox extension designed to assist individuals in the development of web-based applications. While many form helpers already exist, Test Assist takes things to the next level by offering the playback of any mouse or keyboard actions - even across several pages - and records them to an easily-editable file.

Users of Test Assist can choose to playback individual files or multiple files per page, making the testing process an automated breeze. It's an essential tool for those looking to streamline their workflow and ensure that their web-based applications are fully optimized for performance.

To use the extension, all that's required is Firefox 0.9 - 1.0+. Overall, Test Assist is an excellent addition to any web developer's toolkit!
