What was this service/extension called?

Since I can’t think about a search string that would bring it up on the first page in search results… There is a service or some Firefox extension that let’s you use sites where you’d normally need to register but they keep one account in many places and let you use it so that you don’t have to register yourself only to post once for example. Anyone knows what I mean?

Why does Google do this?

I have recently had some searches that give results not expected or wanted. Apparently at least on some occasions Google considers character with and without accent to be equal. In my experience it can be rather annoying. Unfortunately I can’t remember any of my original searches so I made one up. Let’s say you’re searching for “siil naha” (without quotes in search) then you also get results containing “näha” even though it is completely wrong because the meaning of those words are very different. I can understand that with “Émile” and “Emile” it helps but not with every word that has an accented character.
Edit: while I was typing it in I also realised what would be the solution. You can use “siil naha -näha”. Of course without quotes if you’re not searching that specific phrase (and why would you search for such meaningless phrase). Now that I think about it, it would be nice if Google displayed some kind of notice when it uses accent-insensitive search and a clue how to change it to accent-sensitive one. Perhaps some checkbox in advanced options?
Edit 2: after some more careful looking, results containing “näha” also contain “naha” either in text or in links to result page. However emphasizing both words in search results can be confusing. It certainly was for me.

CSS and IE

Those two certainly don’t make your work easy. Whenever you float a div inside another div and also use negative margin, IE thinks it’s fun to not display it at all, unless you add position:relative; to the floated div. Only the newest version can cope without that. I suppose they still make some progress when developing it :).

When you have a link and a list in another list’s element like so:




… then you have to tell IE that it should display a-tag as block or else they end up on the same line. But if I remember it correct then IE6 couldn’t tackle my menu hovering at all, whereas IE7 does it well with some tweaking.
Oh and if any one of you has an idea why 10em border and 10em sidebar don’t have equal width in IE and Opera, do share your wisdom.
