Web browsers aren't geared up for serial downloaders. People who spend their time downloading multiple files from the Internet. For this reason, it's better to integrate a more established download manager in to your browser and let this handle your files, resume files that have not download to your system and even speed up the process of obtaining files from a website.

DownThemAll 1.0 is a free Firefox extension that's been in beta for ages and finally seen a release. It integrates deep in to Firefox and takes over all download management. It will speed up the process of obtaining your files and even download the content from a web page, as well as individual files. You can use the same download manager on OS X or Linux, so you can get used to the way it works across multiple operating systems. It will also work with the beta of Firefox 3.

The addition of web browser tabs was a major feature that has since been implemented across all browsers. Rather than open multiple windows, you can simply open a website in a tab instead. Recently browsers have also had the facility to move tabs around on your interface, which can be useful if like working with your websites in a particular order. However, the problem with any tabbed system is that you can't easily see the open website, especially when you have pages from a site open in multiple tabs. It's not always easy to remember which page is open in which tab.

Firefox Showcase 0.9.4.6 is a Firefox extension that enables you to open your websites as a visual preview located alongside the left hand side of your browser window, rather than along the top as standard tabs. Makes it easier to see the open sites within your browser.
