Firefox 3.6 Beta 1 Available

Firefox can finally orient itself, at least in terms of iPhones and MacBooks. Mozilla's latest browser, , can now talk to accelerometers such as those in many Apple devices, thanks to introduced in the new Gecko 1.9.2 presentation engine at the browser's core. Also among DOM enhancements are drag-and-drop for file transfer and the ability for Web workers to self-terminate.

And that's just the beginning. The download of Firefox 3.6 beta 1 for Linux, Mac OS X and Windows contains thousands of bug fixes, including numerous repairs to CSS image rendering and text alignment.

There also were significant updates to XUL, and separate pages were created to advise extension and plug-in developers of how to update your work. , you'll need to know that main () is no longer supported as an entry point. There are also some user interface changes and Mac OS X-specific mods, and with Gecko 1.9.2, the old Code Fragment Manager will be officially phased out. , the add-on package has been modified, and there are UI and HTML 5 compliance improvements to deal with.

Firefox 3.6 also reportedly supports some aspects of Windows 7, including Aero Peek and taskbar thumbnails (does anyone like these?), but will not support Jump Lists when released later this year.

This thread is a useful historical snapshot — thanks to for the original beta announcement and to for the later update — but Firefox 3.6 is long obsolete. Mozilla ended official support for the 3.6 branch on April 24, 2012; after that date no regular security or stability updates were published for 3.6. (See Mozilla’s support announcement.)

Running an unsupported browser on the open web is a real security risk. Government and CERT guidance for browser vulnerabilities repeatedly recommends moving to a patched, supported browser or isolating unpatched clients until fixes are applied. Treat any system using Firefox 3.6 as untrusted for sensitive work (banking, email, corporate access). (See CISA/US‑CERT guidance.)

If the goal is to move from 3.6 to a maintained Firefox build, back up your profile first, then migrate. Practical checklist: 1) Export bookmarks or back up your profile folder (close Firefox, copy the profile directory), 2) sign in to Firefox Accounts / use Sync or import the backed-up data into a modern Firefox profile, 3) test extensions in a fresh profile before enabling them. Mozilla documents the exact backup/restore steps and file names.

If testing legacy behaviour or running old XUL/XPCOM add‑ons is required, do it in an isolated VM or choose a maintained fork that explicitly supports legacy extensions — for example Pale Moon or Waterfox Classic — but be careful: some legacy forks carry security tradeoffs and notices about unpatched advisories. For safe testing, run the old browser build inside a virtual machine (VirtualBox or similar), keep the VM off the network when possible, and snapshot before you experiment.

Summary: this thread documents an important milestone, but modern security practice is to stop using 3.6 on production machines, back up your profile, and migrate or isolate legacy tests in controlled VMs.
