New In Firefox 3.5

Firefox 3.5 makes surfing the Web easier and more enjoyable with exciting new features and platform updates that allow Web developers to create the next generation of Web content. Native support for open video and audio, private browsing, and support for the newest Web technologies will enable richer, more interactive online experiences.

Performance. Firefox 3.5 includes the powerful new TraceMonkey JavaScript engine, which delivers unprecedented performance with today’s complex Web applications. Firefox 3.5 is more than two times faster than Firefox 3 and ten times faster than Firefox 2.

Open Video and Audio. Enjoy video and audio content from within your browser, without the need for plugins. Video is a vital part of the modern Web, whether it’s used to communicate, educate, or entertain. Firefox 3.5 delivers the first native integration of audio and video directly into the browser. Now everyone can easily watch open format Ogg Theora videos.

Web developers can use these technologies to design pages that interact with video content in new and exciting ways, offering richer interactive experiences beyond controlling playback and volume.

Privacy Controls. Firefox 3.5 includes features designed to protect your privacy online and provide greater control over your personal data.

While using the new Private Browsing mode in Firefox 3.5, nothing you encounter on the Web will be stored from that moment on during your browsing session. Unique to Firefox 3.5, the new Forget this Site feature can remove every trace of a site from your browser. If you want to remove all private data or activity from the past few hours, Clear Recent History, another Firefox-only feature, gives you full control over what stays and what goes.

Location Aware Browsing. Location Aware Browsing saves you time by allowing websites to ask you where you are located. If you choose to share your location with a website, it can use that information to find nearby points of interest and return additional, useful data like maps of your area. It’s all optional – Firefox doesn’t share your location without your permission.

New in This Release

In this release, Firefox has been updated to 3.5.4 (release notes) and removes the prompt to disable session store on first run.

Story Topic:


I had several problems to use Sun Java applications with Firefox Portable. After a long search I decided to use other secondary browser to get Sun Java applications. Today I found inesperately a solution to solve this problem when FF portable is installed in the hard disk. All began yesterday when I was trying to install a program named Spywareblaster(a malware protection program) with no success to protect portable Firefox until I found the solution in one forum. My surprise started today when I installed Sun Java update 17 and all Java Applications started to run like nonportable Firefox was installed in my computer. The spywareblaster solution also makes FF portable to be detected by Sun Java when it is reinstalled, and there is the complete steps:

The first step is to create a folder with the name mozilla located in:


The second file is to create the file profiles.ini and copy it in the above folder. The file profiles.ini must contain the next lines:



After make this, I installed Sun Java and rebooted the system, and now I can use all Sun Java applications with Firefox Portable with no problems at all.
I know this is a little solution and probably it had no effects in USB, but I am very satisfied with this in my computer.
Thank you all, specially to Mr. Haller for FF portable.
