Firefox so slow and Opera won't start

I've always used firefox but latley its become unusable. After a short period my cpu useage spikes to 50-70% and firefox completley freezes. I don't usually have more than 7 tabs (one of them being hulu.com usually) and this problem has just started recently. I figured i'd just switch to opera for a while and see if that fixed the problem but when i try to run opera:

/usr/lib/opera/9.51/opera: error while loading shared libraries libqt-mt.so.3: cannot open shared object file: No such file or directory

however, running "locate libqt-mt.so" returns

/opt/qt/lib/libqt-mt.so
/opt/qt/lib/libqt-mt.so.3
/opt/qt/lib/libqt-mt.so.3.3
/opt/qt/lib/libqt-mt.so.3.3.8

so it appears to be there..

Only contributing factor i could think of would be that i had testing enabled for a couple days for kde4, dont' think i syu'd but i could be wrong.

midori seems to work fine, but its not my cup of tea.

thanks to anyone that can shed light on either of these problems.

Try installing/reinstalling qt3

run "ldconfig -p", and see if those libraries are listed there.  If not, check /etc/ld.so.conf and make sure /opt/qt/lib is listed.

Re: Firefox so slow and Opera won't start

i reinstalled qt3, same prob.
i ran "ldconfig -p" and theres no libqt-mt there (output to long to put in code tags even) so i checked  /etc/ld.so.conf and i found

/usr/lib/libfakeroot
/opt/kde/lib

so i added /opt/qt/lib as suggested but still same problem.

Did you run ldconfig as root afterwards?

Nope, works great now thanks. Didn't know i was supposed to do that. Where can i read up about such things (or what subject should i lookup) so i can troubleshoot this myself next time?

edit: aside from "man ldconfig" i'll read that ofcourse

Re: Firefox so slow and Opera won't start

Okay so ldconfig keeps track of the most recent shared libraries to be used by various programs on my system. I need to have directories where shared libraries are kept listed in /etc/ld.so.conf.

That aside, has anyone else been experiencing any huge slowdowns in Firefox like i am? I find it weird that it becomes extreamly slow (20 seconds to respond to a click i'd say)  yet is only using 50-70% of the procesor, which is still an alarming amount obviously but not 100%.
I was thinking i would downgrade some dependencies and see if it would make a difference so i used the script "pactree" found it the "community contributions" forum to see what was there. There was a ton of dependencies, dependencies, dependencies, etc so i don't really know where to start (well actually i'd assume at the top but..). Can someone confirm or disconfirm that this would be a good way to go about it?

Re: Firefox so slow and Opera won't start

What version of firefox?  Do you have a bunch of addons installed?  Do you have flash installed?

You could try swiftfox from AUR, which are optimized by processor type. 

I'm running firefox 3.0.1 on a 64-bit machine and I can say I have to say it runs pretty well.  I've run the 32-bit one on another machine and had no problems with it either.

Re: Firefox so slow and Opera won't start

FIrefox3 is performing great on both of my machines. As kett asked, I would question your add-ons first if you have any. Badly written extensions can cause all sorts of problems. You also may consider disabling your cache:

Edit-->Preferences-->Advanced-->Network-->Offline Storage

Re: Firefox so slow and Opera won't start

My addons and flash havn't changed. Its just gotten slow recently and its seemingly sparatic, right now i'm in FF and everythings fine, later it may go to a standstill. killing it doesn't help whens its in a slow episode, when i start it up again its just as slow.

plugins:
Java
openoffice.org
shockwave flash

i'm running the latest version of FF via pacman -Syu

Your plug-ins are fine. It's extensions or add-ons like Flash Block, Ad Block, User Agent Switcher -- stuff like that.

Tools-->Add-ons

These aren't great examples though; They all work correctly.

Re: Firefox so slow and Opera won't start

I have no extentions or add-ons so i guess i'll just scratch my head and use opera for a while. Thanks for your help guys

Re: Firefox so slow and Opera won't start

I suggest creating a new profile and seeing if the performance is better.

Re: Firefox so slow and Opera won't start

I used to get spikes in FF3 a lot when scrolling which was slow and jerky with a second or so delay.  if you put 'export MOZ_DISABLE_PANGO=1' into your bashrc/zshrc that solved all the scrolling and spikes you get.  I think what this option does is disable something like anti-aliasing on certain characters (like Cyrillic or kanji I think) but can't remember too well.

Re: Firefox so slow and Opera won't start

FF3 runs really slow for me too, even with only a few tabs open. Some sites can really kill it, and the CPU spikes badly. My hardware is *really* old though. I'm running a 1.7Ghz P4

Opera runs better...
