Firefox 7 Beta Puts Priority on Performance
Just days after the ready-for-primetime version of Firefox 6 was released, Mozilla, sticking to its aggressive development schedule for the browser, has rolled out the beta for Firefox 7 —a release of the software that is emphasizing performance improvements.
Context & Ripple Effects
The Firefox 7 beta is the schedule Mozilla set for itself actually landing: back in February, Mozilla said it would ship Firefox 4 through 7 before the end of 2011, a pace that replaces the old year-plus beta cycles readers remember from the 2009 beta rollout. Releasing a 7 beta days after Firefox 6 goes final is that cadence compressing into near-continuous shipping.
Performance is the stated focus, which lines up with the July work on a redesign meant to make Firefox more responsive — Mozilla is framing each rapid release around engine speed rather than feature drops. The backdrop is competitive pressure on talent too: the lead Firebug programmer left for Chrome in July, and Mozilla has parallel tracks running in 64-bit Windows builds from Firefox 8 and the HTML5-based Boot to Gecko operating system announced the same month.
First-order effects
- Users and testers get a performance-oriented Firefox 7 beta while Firefox 6 is only days old, meaning most of the installed base will be evaluating one version behind while the next is already stabilizing.
Second-order effects
- Chrome's velocity becomes the benchmark Mozilla is explicitly matching, and the July departure of the lead Firebug programmer to Google shows the same contest playing out over engineers, not just releases.
- Extension developers and enterprise testers face a rolling target: with versions 4 through 7 all due inside 2011, compatibility and QA work shifts from per-release projects to a continuous process.
Third-order effects
- If this cadence holds, Firefox version numbers stop signaling distinct products and become checkpoints in a continuously updated browser, with performance deltas — not feature launches — as the story each cycle.
- Mozilla is hedging its dependence on the browser itself: alongside the rapid releases it confirmed Boot to Gecko, an HTML5-based operating system play, pointing toward an organization whose platform ambitions extend past competing with Chrome tab-for-tab.
The trend: Browsers in 2011 are shifting from infrequent major launches to rapid, incrementally numbered releases where engine performance is the recurring headline, and Mozilla's compressed 4-through-7 schedule is its answer to Chrome's pace.
