Mozilla Releases Firefox 9

| Product News

Following its aggressive release cycle, Mozilla released Firefox 9 for OS X, Linux and Windows on Tuesday. This version adds improved theme and gesture support for Lion as well as faster Javascript execution.

Improvements cited by Mozilla include:

  • A 36 percent increase in the execution of Javascript code using “Type Inference.
  • Support for Lion’s two finger swipe gesture for browsing pages, just like Safari.
  • Improved theme integration with OS X Lion.
  • Continued attention to improved memory management.
  • Improved support for text overflow and added support for font-stretch.
  • Added support for querying Do Not Track status via JavaScript.
  • Critical security patches.

The Mozilla download page will detect your OS and offer you the correct version. A more general downloads page covers supported (human) languages.

The release notes, system requirements, known issues, an FAQ and more have been posted. Also, a more detailed, item by item, list of changes in version 9 has been published.

For those who have experienced dizziness and disorientation related to Mozilla’s aggressive numbering scheme for new releases, version 3.6.25 was also released with the latest security patches.

Firefox 9 for Intel Mac only requires OS X 10.5 or later and at least 512 MB RAM.

I checked the stats for browser usage. http://www.w3schools.com/browsers/browsers_stats.asp
Now this might be just my interpretation but FF peaked in the 47% range, in late ‘09 early ‘10. Starting about a year ago that started to decline markedly and they are now at 38%. This coincides with this berzerko upgrading scheme. I know of a fair number of users that stopped updating “until they settle down”. Of course Chrome came into it’s own in that time period as well but I wonder if this Major Upgrade Every Three Months idea is costing them eyeballs. Maybe people got tired of waiting for FF to stay somewhere and went Chrome? I know that as much as I am not fond of Google Applications I’m thinking of trying it for that very reason.

Geoduck.  I’m staying with Firefox for now because it’s produced by an independent organization that doesn’t have the kind of agenda the big guys have. Chrome wants to know too much about my activities, Safari starting with 5.1 left a sour taste in my mouth, and Opera, while very cool, had some irritating nuances that drove me to Firefox.  I’ve been very pleased with Firefox, especially with respect to security and privacy.

And shortly there will be 9.01 to fix the bugs 9.0 has.
I really hate these rapid .0 releases. There really aren’t any major changes warranting a major version number change.

Has anyone noticed the berzerko progress of Chrome version numbers? The difference is that Firefox is nice enough to ask, whereas Chrome just does it without your knowledge. Some like that, but maybe some don’t. Probably many Chrome users just don’t know that it updates itself every five minutes…

What I really want though is for Safari to not s***. But then you’ve said more or less the same in a past article.

Ha!  As I was reading this article, a FF popup opened and told me that I needed to restart FF for version 9 to take effect.  (I have preferences set to update automatically, in case you’re wondering.)

Oh, and iVoid, this is version 9.0.1.
