Chrome: We've mentioned lots of ways to keep your bookmarks in sync across browsers and across computers, but if your bookmarks are older than your choice of browser, it might be time to clean them up, get rid of any duplicates you may have, and get rid of any old, dead links that you may have lurking in an old bookmarks folder from way back. Bookmark Sentry for Chrome does just that. More »

BleachBit -- the open source system clean-up utility for Windows and Linux -- has added several new features to its latest version that make it an even better tool for removing unneeded files files from your computer. Support for Google Chrome and Chromium has been greatly improved: BleachBit can now remove everything from DNS prefetch data, to autofill history and DOM storage. Support for HTML5 localStorage cleaning has also been improved and now works with Opera.

On Linux systems, BleachBit can now remove swap files (in addition to swap devices). The Windows version has added the option to remove Windows Update uninstallers -- including hotfixes and Internet Explorer patches. BleachBit's list of supported programs has also grown significantly since we last wrote about the program, and it's well worth checking out the full list of features to see just how much digital crud it can remove from your hard drive.

One of the most talked about features in Safari 5 has been its Reader function -- Apple's built-in implementation of the Readability bookmarklet. Both are nice ways to reformat articles on blog or news sites for distraction-free reading.

If you like the look of Safari Reader but would rather not change from Google Chrome or Firefox, don't worry. The iReader extension brings the same functionality to your browser of choice!

Like Safari Reader, iReader shrouds the background in semi-opaque blackness . Hover near the bottom of the page to display zoom and print controls, as well as e-mail/Twitter/Facebook sharing buttons. iReader is also highly configurable -- set Gmail as your 'send page' client, change the display font, activate smooth scrolling, set the "curtain" to be more or less transparent, and adjust the reading area and margins. You can also choose hotkey combination to activate iReader (rather than having to click on the Omnibar icon).

I have no idea how long this extension will be around -- has the jury returned a verdict on whether ad-blockers are ethical? -- but for the casual user, minimal.digg is awesome. By removing the fluff, the crust, the non-essential verdigris, minimal.digg gets you to the content faster. In fact, unless you're deeply entrenched in the Digg community, I can't see why you wouldn't use this extension.

Digg has, for the longest time, been a great (if demagogic) link collator. In fact, if you've never visited Digg, install the extension and head on over! Most of the links that arrive via email or instant message were originally dug up by a Digger -- so why not get in at the start of an Internet meme?! Be contemporary!
