Mozilla Firefox 3 Beta 3

Mozilla Firefox 3 Beta 3 is the third test release of the upcoming 3.0 version of Firefox. With tons of new features, security enhancements, performance upgrades and more, it's one of the most widely-anticipated releases this year. And, thanks to the packaging, you can try out all the new features without impacting your locally-installed copy of Firefox. For more on what's new, read the Mozilla Firefox 3 Beta 3 Release Notes.

Minor Update With Revision 2

A minor bug in the first revision of Mozilla Firefox, Portable Edition 3 Beta 3 prevented the What's New page from showing on first launch. This was corrected in revision 2 to ensure that all users would have the opportunity to participate in the beta testing community. If you have Revision 1, upgrading is not completely necessary. Installer / Format

Mozilla Firefox, Portable Edition is packaged in a Installer so it will automatically detect an existing installation when your drive is plugged in. And it's in Format, so it automatically works with the Suite including the Menu and Backup Utility.


Mozilla Firefox, Portable Edition is available for immediate download from the Mozilla Firefox, Portable Edition 3 Beta 3 homepage. Get it today!

There was a small bug in the original release that prevented the What's New screen from showing on first launch. As this is a part of the Firefox beta experience, a quick update to revision 2 was posted to correct this.

Sometimes, the impossible can become possible, if you're awesome!

Just saw this at LifeHacker, came over here, and you've got it!!

For the most part I like the Beta 3 of Firefox, especially the "smart bookmarks." The only problem I have had with it (more of a Firefox issue than a portability issue) is while accessing a PDF document on one site. The Beta 3 firefox timed out while attempting to load the document and view it on the screen, whereas Internet Explorer was able to link with Acrobat and display the document.
Other than that it appears to work seamlessly.

I generally prefer to go into Tools | Options | Content and either remove the PDF extension from the list or configure it to use a particular program. I find that I get a much better "experience" reading PDF files in a PDF reader instead of crammed into a browser page. Not that I like PDF files anyway, but when I have to, I'd rather they be in a reader.

I'd guess one could configure FF to load SumatraPDFPortable as the external reader.


Rab -
The idea of configuring FF to load SumatraPDF as the default external reader is a good one (keeps everything on the flash drive). I'll see how that works out and report back.

I added a new folder under the bookmarks tab and later I could not delete it. Upon restarting my computer the new folder that I wished to delete previously was now gone.

Another issue that I noticed is after I create a new folder I can not drag and drop bookmarked web pages into the new folder.


I went into Tools/Options/Applications and modified the calls to PDF files so that they now call on Sumatra PDF on the flash drive.
Relatively painless to adapt Firefox "auxiliary" programs for total portable operation.
