Mac OS X: Trillian, the slick-looking multi-protocol IM client that kinda-sorta won our Hive Five for best IM app, has launched an early alpha for Mac OS X. It's not close to feature-complete, but it does look like Trillian.

Early reports peg the Mac alpha of Trillian as very rough, and not on the same level as the well-known Windows client. Some preferences are missing, Growl support isn't there, and, as Download Squad notes, the chat alert sounds are annoying and hard to turn off. That said, the client has a smooth look to it, and, while Adium is the well-tested standard for multi-protocol chat on Macs, if you're familiar with Trillian on Windows, you'll probably enjoy the Cocoa-ed version seen here.

Maemo5 Phones: Moving right along from the release candidate, Firefox Mobile has arrived in 1.0 form on phones like the N900 that run Maemo. It's got add-ons, an AwesomeBar, desktop syncing through Weave, and plenty more to recommend it. We just wish it could work on more devices.

Windows: If you use a 3rd-party application dock in place of the Windows taskbar, you may have noticed that you can't completely get rid of the taskbar. Taskbar Eliminator helps you turn it off and keep it out of the way.

You can minimize the taskbar in Windows but you can't full-out remove it. This can be a bit of a pain if you're happily using a 3rd-party application dock and you don't like the taskbar popping up or even taking up that tiny sliver of screen real estate to say "I'm here!". Taskbar Eliminator is a single-purpose application that removes the taskbar from the screen and keeps it from popping up or getting in the way, letting you use your 3rd-party dock in peace.

Firefox: As you make the rounds commenting at your favorite blog or composing a lengthy email, avoid misspellings or a bad turn of phrase with After the Deadline's excellent grammar and spellcheck Firefox extension.

This nifty little add-on hides in the background on Firefox until you're ready to use it. The next time you visit a message board, fill out a web form, or leave a comment on your favorite web site, just hit F7 on your keyboard before you send your message into the intertubes. The extension checks for spelling and grammatical errors and underlines them in hard-to-miss bold colors.

Windows: WinPatrol Plus is a powerful Windows monitoring tool which regularly retails for $40. It's available, today only, for 99 cents.

WinPatrol Plus continually monitors your system and takes system snapshots to record system changes, critical spikes in resource usage, and other events you want to be alerted of. If you want to monitor your system and keep tight control over aspects of it like what programs launch at startup or run in the background—no matter how deeply buried in the system they are—WinPatrol is a great tool for doing so. You can visit the author's site for more information or jump directly to the Yahoo! store that processes the orders—in case the offer today tanks the author's site.

Mac OS X: Two years ago we showed Windows users how to upload old and archived email into their Google Apps mail account. Now the same functionality is available for Mac users.

Google Email Uploader for Mac is the Mac-centric version of the Windows version we've previously introduced you to. Like the Windows version, Google Email Uploader for Mac helps you take email you have archived on your computer and insert it into the Google Apps mail account. Google Email Uploader supports Apple Mail, Eudora, Thunderbird and other applications that use mbox or Maildir archives to store email.
