[gentoo-user] Firefox Keeps Hanging on some pages

[Ow Mun Heng]

Upgraded to Firefox-1.5.0.6
access http://zedomax.com

and it hangs for whatever reasons.

My GCC is 
$gcc -v
Thread model: posix
gcc version 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9)

My GCC settings is sane

/etc/make.conf
CBUILD="i686-pc-linux-gnu"
CFLAGS="-O2 -march=pentium3 -pipe -falign-functions=64 -mmmx -msse
-msse2"
CHOST="i686-pc-linux-gnu"

I've tried installin the bin version "mozilla-firefox-bin" and it works
OK on the page above.

Note : It hangs (up to the point where the little 'circle" also stops
moving.

Two questions related to your compiler flags. Is there a specific
reason -falign-functions=64 is used? -O2 implies -falign-functions so
unless you have a specific need for a 64 byte alignment, it's
redundant. Secondly, AFAIK the Pentium 3 doesn't have the sse2
instruction set, only P4's do. I don't know firefox's code too well
but it's possible these random sites are triggering a branch of code
that calls sse2 code and firefox is gracefully choking.

And related to these sites that firefox chokes on, are there any
common elements they all share? Perhaps a plugin or something thats
called?

Also, could you post your emerge --info?

This make.conf flags were set like close to 3 years ago so I can't
remember the research that went into it's selection.
I'll remove it

Thsi is a pentium M.
http://gentoo-wiki.com/Safe_Cflags#Pentium_M.28Centrino.29.2FCeleron_M_.28Intel.29

hmm.. GCC-3.4 has it removed. Guess I'll remove it as well.

New Make
CFLAGS="-O2 -march=pentium-m -pipe -fomit-frame-pointer" (Per the wiki)

I'm not sure. I'm seeing this issue from basically clicking on Liferea
(RSS reader) links and it's supposed to open up firefox browsers and I
just noticed it from there onwards.

Flags are sane. :-)

Do the errors crop up only when you open firefox by clicking through
liferea, or do the errors also appear when you visit the pages
manually?

I did some digging with google and there does seem to be some problems
with using liferea & mozilla/firefox together. Is liferea opening a
firefox window within itself (similar to those annoying apps with a
builtin MSIE browser) or is firefox opening the URL itself?

Like the earlier page - Zedomax, it's choking up even when it's opened
manually. (i even got to the point of mv ~/.mozilla ~/,mozilla-old to
test things out.

hmm.. didn't realise that but.. anyway.. it's not only happening
_together_

no.. it' opening it as a windows (or a new tab)

I suspect the problem may be due to the loading of flash (flash 9??) and
I only have flash 7 installed.
I've (re)installed flashblock. and it seems it can open  www.zedomax.com
properly. (But it still "hangs" halfway for like 2 secs before it the
circle thingy moves again.
