I have the same problem with debian unstable Mozilla 1.4 
on an AMD 2400+ with 1 gig of ram and kernel 2.4.21. 

http://www.twistedmatrix.com/documents/TwistedDocs/current/api/ is my particular
bugbear. I have a local mirror of it (under file:///usr/share/doc/...) which
seems even slower to render.

Right clicking on one of these pages uses full CPU for several seconds.

WFM, Gecko/20031207 Firebird/0.7+, Windows XP, also i doubt that this is
Firebird specific...

It is a huge table full of links.  There is an unclosed named anchor A
NAME="ALGUS" that causes everything to underline when hovering over it.

About the hovering issue, that is bug 117806 (marked INVALID). The performance
on this page, which is what this bug is about, works just fine. Please retest
and if it works marks it as such.

Marko,

Can you please re-test with the latest nightly build of Firebird and report back
if your problem is resolved?

Marking WFM based on several comments. No reply from reporter. Please reopen if
you can reproduce this with a current build.
