A quarter-century of Firefox (versions)

Has it already been 25 versions, Firefox? Actually, given decimal versioning, it’s probably been a lot more, but this one introduces a neat new web audio feature alongside several other tweaks and fixes. Have a look.

Web Audio

We’ll admit it – we really liked this Minecraft-y demonstration of the positional audio features new to Firefox 25. Moving around the environment changes the sound in a believable, consistent way. (And the song, by composer Adam Hagstrand, is just lovely.)

More web audio

There’s even a brook nearby that babbles convincingly. Pretty cool stuff.

Firefox 25
Changed the find bar

The little control+F bar at the bottom-left of the window doesn’t share text between different tabs, eliminating a hinky behavior that devs had complained about in the past.

Nice to see you back!

New Firefox users – or those who have returned after lengthy absences – are now automatically offered the option to import their history and settings and what-not into FF.

Stickier sessions

Browser sessions will be more persistent after an update or restart, a move designed to make Firefox use more seamless, particularly on Android devices. Never fun to lose an important page.

And the usual security fixes

Developers fixed 10 distinct security issues in Firefox 25, half of which were rated critical. The most serious bugs centered on memory corruption issues, including several use-after-frees.
