"OK, don’t laugh," an email we received from a Bing representative began. "I’m really e-mailing you about a toolbar, but it’s actually pretty cool."

Yes, Bing has a new toolbar, or "Bing Bar" if you will. It includes things like Bing Search, Facebook, email, Bing Rewards, Maps, Games, etc. 

Google users may notice a new top navigation bar across Google search, Gmail, and possibly other Google services. 

Google’s statement: "Last week we tested a new top navigation bar, which increases consistency across most of Google’s properties and is a visual update over the previous top navigation bar. We are now rolling this new bar out widely."

Digg has launched new extensions for the Mozilla Firefox and Google Chrome web browsers.

Google made a couple of announcements today that actually combined for perhaps a more interesting announcement than either of them as stand-alone news items.

An extremely popular Internet radio service has finally acknowledged two of the top social media sites.  Thanks to a new feature, Pandora users can now easily spread the word (or note, as it were) about good music to their Facebook friends and Twitter contacts.

Google has a post up talking about how the company uses data it collects from Google Toolbar users, specifically in relation to its enhanced features. These features are opt-in.

Search guru Danny Sullivan got an early scoop on a new Google Product that wasn’t supposed to be announced until later today. Its called the Sidewiki, and is a feature of the Google Toolbar. What it does is allow users to comment on any page on the web. These comments can only be viewed by others who have the toolbar/sidewiki installed.

If you use Firefox, you are no doubt aware that there are many add-ons that can enhance your browsing experience. Many of these can make your online life a whole lot easier and save you time. Following are some that I have found particularly useful. Which do you like? Tell us.

A while back, StumbleUpon launched web stumbling, which allowed users to enjoy their StumbleUpon experience without having to download the toolbar, which was previously a requirement. If you’ve been a user of the service for a significant length of time, you’ve probably grown quite accustomed to that toolbar. Sometimes I forget it’s not just part of Firefox.

There has been a lot of talk about the DiggBar and its handling of URLs this week, after the company implemented some changes in its service. To clear the air, Digg has addressed the situation.

Digg CEO Jay Adelson issued the following statement on Digg the Blog:

Today Google made a couple of announcements involving the expansion of offerings into more languages. They’ve announced that the new optimized SERP pages for iPhones, Android devices, and feature phones are now available in over 60 countries and 38 languages. In addition, the company has announced an advanced translation feature in the newest release of Google Toolbar for Internet Explorer.

Yahoo has introduced a new version of the Yahoo Toolbar today. It runs on Internet Explorer 6+ and Firefox (as a beta).

"The new Yahoo! Toolbar now offers greater customization and more immediate access to the information you care about most from across the entire web – not just Yahoo! sites," says Burke Culligan, Senior Director of Yahoo Front Doors.

StumleUpon announced today that it has launched a new URL-shortening service called Su.pr. The twist, however, is that this one is designed to help content creators actually increase their traffic with it. According to StumbleUpon, this is the first such service that does this.

Earlier this year, LinkedIn started offering a news sharing feature. Now any user that clicks through an article shared on a LinkedIn group will be able to share and comment directly from the news article.

AOL has released a new search Toolbar for Firefox, Internet Explorer and Flock. It requires Windows Vista or XP or Mac OS X. You can get an idea of what it looks like from the image below.

The AOL Search Toolbar allows users to: 

Remember in late February when a new Digg Toolbar was uncovered via an image on Flickr? It was said to be coming out to take on StumbleUpon and TinyURL (and similar services) at the same time.

Well now we get a closer look at that as Digg prepares to roll out the DiggBar. Kevin Rose posted about it at Digg the Blog today and included the following video, which shows just what it does.

Twitterer Veronica Belmont had discovered a Flickr page with an alleged upcoming toolbar from Digg that would potentially rival StumbleUpon.
