Mozilla Thunderbird portable 2.0.0.23: real email, on the go™

Thunderbird makes e-mailing safer, faster, and easier with such features as intelligent spam filters, a built-in RSS reader, and quick search. Thunderbird was designed to prevent viruses and to stop junk mail so you can get back to reading your mail. Thunderbird provides effective tools for detecting junk mail. Its tools analyze your e-mail and identify those that are most likely to be junk. You can automatically have your junk mail deleted or you can put it in a folder you specify, just in case you like reading junk mail.

View your e-mail the way you want it. Access your e-mail with Thunderbird's new three-column view. Customize your toolbar, change its look with themes, and use Mail Views to quickly sort through your messages.

Mozilla Firefox 3.5.3 Portable: your browser, your way... in your pocket™

Firefox 3.5 hardly includes any outstanding features, at least regarding the browser's external appearance. Web developers though will be glad to know that the new Firefox supports CSS 2.1 and CSS 3 properties, has improved Web standards in the Gecko layout engine and now features a much more efficient Tracemonkey JavaScript engine, which means that websites will now load significantly faster.
But what about the average Firefox user who spend a few hours every day browsing the web? Well, there are certainly a few new features that make the new Firefox even easier and more comfortable to use. One of them is the Awesome bar, which has been improved and now accepts special characters with which you can filter and narrow your searches. Browsing history has also been enhanced, with new tools to clear browsing traces from just the past two or four hours, or from a specific website only thanks to the "Forget about this site" option.
Other interesting features included in Firefox 3.5 are the Private Browsing mode (which lets you browse the web without leaving any traces behind) and support for Open Video, which enables you to right-click on certain videos and access extended options to control,
Video integration has also been improved in this version of Firefox. When you open certain videos, you’ll able to right-click to display options that allow you to control, save or send the video, among others. Flash videos don't seem to be supported though.
The new Firefox 3.5 includes many new exciting features that will make your web browsing even more enjoyable.
OS requirements: Win2000/NT/XP/Vista/7 .
