How to Make an iPhone Screenshot

Want to take a screenshot of something on your iPhone or iPod touch? Press the Home button and Power button briefly at the same time, and an image of your screen will be saved to the Photos app (and will sync with iPhoto when you next connect). Don't hold the buttons too long or your device will either power down or reboot.

Firefox 15.0

Send Article to a Friend

Mozilla has released Firefox 15.0, which is highlighted by improvements to how the Web browser handles certain third-party add-ons to reduce memory usage. As noted in a Mozilla blog post, the most common cause of memory leaks is “when an add-on accidentally holds on to extra copies of a Web site in memory after (the) user has closed the tab.” The new release detects when an add-on is piling up pages — and memory — and subsequently stops the process and recaptures the leaked memory.

Firefox 15.0 also promises an improved 3D gaming environment with smoother animations thanks to an improved JavaScript engine and native support for compressed textures in WebGL, plus high precision timing for responsiveness within thousandths of a millisecond. Other changes include a new JavaScript Debugger added to the developer toolset, native support for the Opus audio codec, support for SPDY networking protocol v3, and Maithili language localization. Finally, Firefox 15.0 introduces optional silent background updating, which will download and install improvements and then implement those changes the next time you launch the Web browser. Perhaps this feature spells the end to having to pay attention to the increasingly uninteresting details of Firefox releases. (Free, 32.6 MB, release notes)
