DownThemAll: DownThemAll! 1.0 Beta

This is an old beta release. A stable version was released in the meantime and should be used!

We are proud to release the second beta version of DownThemAll! 1.0.

This beta features a real lot of bug fixes and redesigns, concerning both the user interface as well as the algorithms and technology.


A beta version is an (almost) feature complete test version that is still in development. There might be bugs, so don’t be surprised if you encounter some issues.

We developers depend on the feedback provided by our testers, so that we can sweep out remaining issues and finally release a stable version.

If you’re not an experienced computer user, and if you don’t want to manage problems you may encounter when using such a test version, then please don’t install this beta!

If you find real bugs or other issues, then please don’t hesitate to file a bug.


Either install the XPI directly (this requires that you add this site to your allow list for software installation)
