Well, I never heard of it, but they’ve been here since July 7, 2005.
I found a link to the new Google Toolbar for FF on the main Google page and from there a link to the Google Firefox extensions page. Apparantly Google has already made three extension, being ‘Google Toolbar’, ‘Google send to phone’ and ‘Google Suggest’ of which the latter is my favourite: it auto-completes search terms that you enter in the Firefox Search bar.
Another interesting note I found was in a recent GoogleBlog entry by Justin Voskuhl, in which he thanks the Mozilla foundation for their easy XUL language and “for making it so easy for [them] to look good”
Not that long ago, the Google Firefox Toolbar team met for the first time – and now we’ve built the Google Toolbar for Firefox in 10 languages for three operating systems (Windows, Mac and Linux). Self-congratulatory urges aside, we marvel at how well-suited this platypus was to our task. For a small team that had never worked together, or used XUL, to create a product quickly that works across languages and platforms from a single ~250K download – that’s good stuff, if you ask me.
I think it’s great to see Google working close with firefox, and that not just being delivering a startpage, but also neat extensions that give you new features like Google Suggest. The fact that they’ve finaly started to develop the Googlebar for another browser than IE and hearing that they actually prefer this new open source way just makes my day 
[...] y Google has more than just the toolbar for FF, they have two other extensions. Hat tip to Usayd Networks for that one. I’ve seen Google Suggest before, but the webpage, not the extension. Looks [...]
Hey tibo thats very cool, i’m also trying out the google suggest feature for the search in the top right. I don’t want any toolbars on my FireFox, however, because I really dont like the use of them when you can have all the features built in!
