The bar now floats at the top of the google homepage - regardless of whether you are using iGoogle or not. I haven't bothered to investigate how to or if you can get rid of it but I thought I'd let you know that it's not just your iGoogle page.
Some firefox extension that edits css (edit css I think is the name) would work to make it transparent. But it is normal.
You can use RIP in Firefox (Remove It Permanently)
I did it once, ef'd up every other google page I ever visited so I removed the RIP.
Yeah, it didn't look nice :/ In Firefox with FireBus (but i'm not sure), You can style it, or completly remove (make div display parameter -> none).
Hm...i've tried CSSedit....but i don't think it can remove that thing. Hm... i don't imagine how i can load a different css every time i enter the google page. That little extension doesn't have this option.
I've tried that permanent remove extension.. and it works partially. It removes half of that bar... and only the writing.. so... it is not what i needed.
Anyway ... 10x for the reply. I will try to live with it.... That bar is not like a banner or a flash... complex extensions to remove it ... i don't think that exist.
(...) and i didn't find anything like FireBus.
Try GreaseMonkey (firefox extension), it will be able to remove it but it's powerful and might require you to learn what about it first. Of course, someone may very well have already posted the code you'd need to make it do that. I'm sure you can't be the only person to find it annoying.
