Once you've installed and restarted Firefox, you'll have a new Downloads tab in Options. Ad well as the usual download options, Download Manager Tweak will have added new abilities. You can now choose to open the download manager in a sidebar or as a new tab, removing the normal extra window that Firefox uses. There's also a download toolbar, which is customizable.
The toolbar has a Launch, Open Folder, Delete File and Remove File buttons. The download information is also expanded slightly.
Download Manager Tweak doesn't add a great deal to Firefox, but being able to choose where the manager shows up is nice. Opera keeps downloads inside the browser, and feels much more modern for it, so having the same option for Firefox can only be a good thing. The other Download Manager Tweak additions are pretty minor.
Download Manager Tweak is useful, but doesn't do enough to become an essential Firefox Add-on
- Removed references to old .dtd files to be compatible with Firefox 3.7a1 Updated or new translations for ru-RU and et-EE from babelzilla.org Fixed a bug where button icons were not always updated when a download completed Changed sidebar view to always display toolbar buttons as icon only Use Firefox's built in active download count to improve handling of auto open and close Replaced .css reference of .button-box to hbox so that vista-aero theme works
