User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; hu-HU; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; hu-HU; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

Inside a fieldset there are _only_ float elements. Anyway, he height of the
containing fieldset grows till the height of the inner part.

Reproducible: Always

Actual Results:  
Now the height of the containing fieldset grows till the height of the
contained float elements.

Expected Results:  
The float elements should stretch beyond the fieldset (see the screenshot).
References: it works well in Opera8, Safari1. It works badly in IE,
Konqueror 3.4, Opera7.x

Fieldset is a block formatting context root in Mozilla.  Hence the behavior you
observe.  Since behavior of fieldset can't be described by CSS, in general, this
is in fact allowed by the spec.

Similar to this, I'm getting "clear: both" ignored inside fieldsets. A workaround seems to be to add a border to the DIV you want the clear: both to work for.

Per HTML 5, fieldsets establish a new block formatting context, effectively making this bug invalid.

I'll try to find out whether this was a bug in Fx 1.0; if so, I'll add a reftest later.

Ah, that was bug 309550. There was no reftest added, so here's a quick one.
