There are lot of tools created that help web developers. However, it is very hard keep track of these tools. So how would it be if there is a centralized index where you can go and look for these tools. With this thought in mind Mozilla has created a GUI based web index that is good looking and easy to use.
As we’ve explored different tools we could create here as part of the Developer Tools Lab, we’ve come to the opinion that in addition to creating new tools, one of the best things we could do is help developers understand the broad universe of tools that already exist and expose some of the fantastic and amazing work that’s being done.
The Open Web tools Mozilla Directory is built for modern browser like Firefox 3.5, Safari 4, Chrome 2, or Opera 9. There might be some issues with IE for which Mozilla tools directory offers a link based simple tool directory.
At the moment there are only few tools available, however Mozilla is actively working to add more. You too can contribute to the directory in case you are relevant to other tools that are amiss on Mozilla web developers tool directory. They have prepared a data entry form for you to use to submit a tool, go ahead help yourself, Open Web Tools .
