I like to keep my [browser] toolbars simple. I've seen toolbars stacked 8 deep and I think that's wasted space. But, every once in a while a toolbar comes along that I can get behind. Here's the toolbars I've installed this week:

• Google (official) Toolbar BETA for FireFox - This is the official Google one with PageRank, not the GoogleBar from MozDev we've all no doubt be running previously. I've disabled the GoogleBar and installed the new one, and I'm digging it.
• The Google Suggest FireFox Extension - The toolbar is nice, but it's not for everyone. This is a little gem that you may have missed in the cacophony. This extends the standard/existing Google Search box that all FireFox installs have to include Google's AutoSuggest feature. With this you get a greatly enhanced without the emotional baggage of a new toolbar.
• The MSN "Suite of Goo" aka MSN Search Toolbar - The MSN Toolbar has been updated and this time I took the plunge. Not for the Toolbar, no, I don't show it (right click, deselect), but for the Tabbed browsing. It's a hack, sure, and yes, I know there are a dozen browsers that host IE and offer tabs. I only use IE when I need oddpost, or visit the occassional site that hates FireFox, but when I do show up, I'd like to have tabs. Also, it's nice for my mom. Plus, the Desktop Search gets better and better. I've switched over from Google Desktop Search.
• Del.icio.us Bookmarklets - Not exactly a toolbar, but I've dedicated space to Del.icio.us bookmarklets on ALL my PCs. What a brilliant and simple way to keep my bookmarks in one place. I save SO much more than I would with standard Bookmarks (which are a hassle to sync between n=browsers*PCs no matter what folks say. I haven't even dug into the social aspect of Del.icio.us. I'm too busy saving things!
• GenPass Bookmarklet - A great little tool for creating complex passwords that are site specific. Generates passwords that you never see, so you can't give them up under torture. There's a feature I can be in support of. You never know when I could be tortured for my Google Adsense password. If I had a nickel...
• Web Developer - OK, I didn't install it this week per se, but it's still wonderful. If you don't know what it is, and you have FireFox, go get it. If you don't have FireFox, it's the best reason ever to download FireFox. Run. Now.

It's getting to me quite the "me too" game with Microsoft and Google. Seems like when Google comes out with the Whatever.Google.com subdomain that Microsoft immediately offers the Whatever.MSN.com subdomain. Can't we all just get along?
