Firebug is an extremely popular web development tool that allows a user to inspect and modify page elements in real time, be it HTML, CSS, or JavaScript. It’s most known for being a plugin for the Firefox browser, but thanks to Firebug Lite and a little bookmarklet hack, you can run Firebug Lite directly in Safari on iOS.

Using Firebug in iOS is easy, here’s how, as discovered by Martin Kool:

• Bookmark a web page from Safari in iOS and rename the bookmark to “Firebug”
• Tap the text region below twice and “Select All” then choose “Copy”
• Now edit the Firebug bookmark you made, and remove the URL, replacing it with the javascript you just copied
• Tap on “Done” and then hit the bookmarklet to activate Firebug Lite on the iPad

If you’re having troubles with the code from pastebin, head over to Martin Kool’s tumblr for another way to capture the bookmarklet. For screen real estate purposes, Firebug will look best on the iPad, but it works on the iPhone and iPod touch with Safari too.

You probably won’t be getting tons of serious web development done with this, but it’s a great trick and definitely usable enough to make minor changes and quick adjustments to web elements while using iOS.

Apple has posted the second beta of Mac OS X 10.7.3 for developers, available now from the Mac Dev Center. The focus is on Spotlight, Safari, iCloud Document Storage (does not seem like the hidden iCloud file sync feature is coming anytime soon), Address Book, iCal, and Mail, and no known issues exist with the current build, according to MacRumors.

The first developer beta of OS X 10.7.3 was pushed out on November 15, and Mac OS X 10.7.2 was released about a month prior to that through Software Update. It’s unknown when the final build of 10.7.3 will be released to the public, but we’ll keep you updated.

NOTE: New instructions are available to change the login screen background image within OS X Mavericks. Please refer to those if you are looking to customize the login wallpaper in the latest versions of OS X.

Here’s how to change the wallpaper that lies behind the standard login screen on OS X Lion & Mountain Lion (although not the login background you see if you have FileVault enabled, which cannot be altered). As such, this tweak is not for the fainthearted because it involves editing system files and will therefore affect all users of the system. Previous tips here at OSXDaily have explained how to change the login screen background in prior versions of OS X, but OS X Lion and OS X Mountain Lion changed everything (again).

For OS X Lion & Mountain Lion, the file we need to replace is called NSTexturedFullScreenBackgroundColor.png and is located at:

If you’ve been following the Carrier IQ brouhaha and ensuing fallout, you might be interested to know that it’s very easy to disable the Carrier IQ service, logging, and reporting on iPhone or any other iOS device:

• Tap on “Settings”
• Go to “General” and tap on “About”
• Tap on “Diagnostics and Usage”
• Tap on “Don’t Send”

If this was already disabled for battery saving purposes or whatever other reason, you should have nothing to worry about, if not, then this should prevent Carrier IQ from sending any data over to Apple.

For some background here, Carrier IQ is network diagnostic software that some cellular carriers have been installing on smartphones and tablets. Going beyond just gathering network diagnostics, Carrier IQ was found on some Android phones to be gathering personal and private information, including phone call logs, text message content, and even encrypted web searches, or, put simply, it’s a substantial invasion of personal privacy. Later, renowned iOS hacker chpwn found references to Carrier IQ in some versions of iOS, but it isn’t nearly as nefarious as what was discovered on Android, doesn’t track nearly as much personal information, and thankfully, it’s much easier to disable.

Keep in mind that Apple also told WSJ’s AllThingsD that they stopped supporting the feature in iOS 5 for most of their products, saying the following:

“We stopped supporting CarrierIQ with iOS 5 in most of our products and will remove it completely in a future software update. With any diagnostic data sent to Apple, customers must actively opt-in to share this information, and if they do, the data is sent in an anonymous and encrypted form and does not include any personal information. We never recorded keystrokes, messages or any other personal information for diagnostic data and have no plans to ever do so.”

We should expect an update to iOS in the near future to address this on any remaining devices.

Command line users who wish to add an additional layer of security to their keyboarding within Terminal app can find a helpful privacy feature built into the Mac client. Whether aiming for generally increasing security, if using a public Mac, or are simply concerned about things like keyloggers or any other potentially unauthorized access to your keystrokes and character entries, you can enable this feature in the Mac OS X Terminal app to secure keyboard entry and any command line input into the terminal.

Mission Control in Mac OS X groups together thumbnail previews of windows from the same app. By hovering the mouse cursor over a cluster of these thumbnails and scrolling up on a multitouch trackpad or Magic Mouse (or scrolling up the mouse wheel with other mice), you can cause the cluster to expand, showing more detail in those behind the main window. Give it a try now—it’s pretty useful.

This short clip of Steve Jobs sharing his thoughts on life is well worth watching. Taken from a 1995 interview when Jobs was still working at NeXT, he reflects on some important lessons and simple facts about life and the world around us. Here’s a great inspirational quote:

“Everything around you that you call life, was made up by people who were no smarter than you”

It’s just under 2 minutes long, don’t miss it.

The Holiday season is here, and what better way to bring the Holiday Apple cheer to your home than some iPhone and iPad ornaments hanging on your tree. Sure, you can buy some of these from an Etsy store that MacTrast found, but realistically you can make iOrnaments yourself just by printing out high quality press images for the iPhone and iPad. You can find examples from Google Images or get press packs directly from Apple:

• iPad press photos
• iPhone press photos

Print them out, grab a pair of scissors, some glue and some cardboard, and make your Christmas tree the envy of the neighborhood.

Mac users may have noticed that the longstanding “Save As” function has disappeared as of OS X Lion, and’Save As’ is something that many Mac users have become accustomed to using over the years. The default choices replacing “Save As” are two different features, Duplicate and Export, neither of which work quite the same, and neither of which are attached to a keyboard shortcut.

If you want to get your “Save As” function back on the Mac again, we will show you how to create your own keyboard shortcut to mimmic the old behavior of “Save As” so that when you hit Command+Shift+S, a Save (Export or Save As) dialog box will appear, allowing you to do the exact same Save As function that existed before.

This is a neat little hack that lets you activate any stack within the Mac Dock by hovering over it and making the scroll gesture on a multitouch trackpad or Magic Mouse, or by rolling the scroll wheel on a mouse.

Do the same trick while hovering the mouse cursor over an app icon in the Dock, and App Exposé will activate. You will see open program windows for that particular app and—with compatible apps—the app’s document history. This is similar to the App Exposé option within the More Gestures section of the Trackpad entry within System Preferences.

Safari 5.1.2 has been released, and if it sounds like just another minor update to put off, it’s not, it improves overall stability and resolves some of the annoying memory management issues that existed in the prior versions of the browser. Also fixed is the flashing page issue, and a problem with displaying PDF’s within web pages.

You can update through Software Update or download Safari 5.1.2 directly from Apple.

Installing Safari 5.1.2 requires a reboot, and is available for Mac OS X Lion 10.7.2 and Snow Leopard 10.6.8.

Need to adjust Mac Mail app so that it sends new email compositions as plain text? This can be a popular change for some email situations, and it’s easy to make the adjustment to plain text emails in Mail for Mac.

Email defaults to wanting to send as rich text, meaning bold text, highlighting, fonts, italics, and the usual formatting options that correspond with page layout and fancier looking mail messages. But when you’re sending a lot of emails across platforms, say from Mac OS Mail app to Windows Outlook, for example, it can be a good idea to use the ‘Plain Text’ format for all email correspondence. This can help to avoid any font or formatting irregularities and size oddities when sending emails between platforms that may interpret the mail text formats differently, a situation that can be particularly obvious when sending from modern operating systems to more outdated versions (like Mac OS to Windows XP). Fortunately, you can adjust the Mail app in Mac OS to default to send emails as plain text, eliminating any potential issues.

A wide variety of websites and online services are region restricted to the USA: Hulu, Netflix, Pandora, annual credit reports, some banks, the list is significant. Region restrictions are generally something you don’t notice until you need to access a website from outside the USA, and then they’re a huge pain. We’ll show you how to get around region restrictions securely by using a SOCKS proxy and SSH tunnel.

The smartphone discussion is typically focused around iPhone and Android, but Microsoft is still cooking up it’s own unique smartphone OS: Windows Phone 7. Now thanks to an HTML5 demo, the curious can try out a basic Windows Phone 7.5 experience directly on your iPhone.

Open up Safari and throw in the following URL:

• http://aka.ms/wpdemo

If you haven’t used a Windows Phone before, the first thing you’ll notice is the similarity to the upcoming Windows 8 OS, which Microsoft says is the future of their desktop and tablet efforts (and probably smartphones too). Lots of tiles, swiping around, it’s fast and fluid and an enjoyable enough GUI. Perhaps best of all for, it’s original, as opposed to the shameless borrowing everyone else seems to have done with iOS.

Is this demo going to swing you away from an iPhone? Doubt it, but it’s always fun to see what the competition is cooking. (via Gizmodo)

Flick down with two fingers on a trackpad or Magic Mouse in Mac OS X and you’ll experience inertial scrolling, where after your finger has stopped moving the page continues to scroll in the intended direction until it slowly stops. This fluid and natural scrolling experience comes from the iOS world, and while it works quite well on the desktop, it’s not for everyone.

iOS 5.1 beta 1 continues to spill the beans for Apple product ID’s, with the latest find being a direct reference to Apple’s next-generation iPhone, referenced as “iPhone 5,1”, and two unreleased iPad’s, referenced as “iPad3,2” and “iPad3,3”.

iPhone5,1 would technically be the sixth generation iPhone, which may indicate iPhone 6 is the proper name for the device. Of course, nothing but speculation is known about the iPhone 5 (6?), but references appearing in current iOS 5.1 beta builds suggest there are working prototypes that are running iOS 5.1 right now in Cupertino. Most rumors suggest the next generation iPhone will have a 4″ screen, a thinner aluminum enclosure, and likely an A6 CPU, and a release time frame could be somewhere between summer and fall of 2012.

The iPhone 5,1 reference was first discovered by @Filippobiga on Twitter – you can follow us there too – who also pointed out the references to two unreleased iPad 3 models, also shown in the screenshot as iPad 3,2 and iPad 3,3. Presumably, those are for the upcoming iPad model that is expected to debut sometime in early 2012 with a retina display.
