209869 - Mozilla 1.4 rc2 as well as Firebird 0.6 hangs on attempt to load the page. Mozilla 1.3 loads it just fine.

Status: RESOLVED DUPLICATE of bug 205778

(Core :: MathML, defect)

Description

[Kirill Lapshin]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030612
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030612

Both Mozilla 1.4 rc2 and Firebird 0.6 hang on attempt to load
http://openmathtag.sourceforge.net/OMT_demo_interactive.php. At the same time
page loads just fine with Mozilla 1.3 or IE 6 with Mathplayer.

Basically page has some MathML content with local xml schema and (probably) xslt
transform.

According to W3 recomendations to provide MathML content uniformly to major
browsers, one has to serve content in text/xml mime and supply one of the
recommended xslt stylesheets. To avoid IE security, one has to copy
xslt-stylesheet to the same web-server which servers the page (otherwise IE will
not execute it). I tried to follow these recomendatains on my web-server but
found out that it hangs Firebird 0.6. So I had to check for browser type and
supply xslt-stylesheet for non Gecko-based browsers since Gecko works fine w/o
stylesheet. I filed a Firebird bug (208184) and Firebird guys quickly discovered
that it does not work for Mozilla 1.4 as well and hence not a Firebird bug. I
was expecting them to hand over this bug to Mozilla, but they did not semm to do
that, so here am I, verified this bug on 1.4 rc2 and trying to catch some
attention on Mozilla team.

I don't have a test case on my web-server at the moment, but I am pretty sure
the http://openmathtag.sourceforge.net/OMT_demo_interactive.php has the same
problem I've seen on my own page. If for some reason the above mentioned
openmathtag url is not available anymore, I can easily reproduce it on my page.

I hope this bug will be fixed soon, it is a pity to see that MathML capability
degraded severely since version 1.3.

Reproducible: Always

Steps to Reproduce:
1. Start Mozilla 1.4 rc2 (or rc1 or Firebird 0.6)
2. Open http://openmathtag.sourceforge.net/OMT_demo_interactive.php


Actual Results:  
Hang
