Why is Firefox "lagging" with certain websites ?

Why does it seem that http://www.bing.com/weather/ (and certain others) (I'd say 97-98 % of the time) cause the Firefox "not responding" message ? Granted Firefox recovers usually within about 30 seconds BUT it's getting to be really annoying because it seems that it's an ongoing problem.

Firefox cannot load certain websites and I've tried all suggested options to fix the problem.

I cannot load certain websites (my bank, some public/civic offices, etc.) on Firefox or Internet Explorer (I usually use Firefox) and have tried all the suggested options in Firefox Help to remedy this problem: clearing cache and cookies, making sure no proxy is selected, allowing cookies). How do I fix this? I use a broadband internet connection that is shared.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
 To Enable SafeMode 
*You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
*''Once you get the pop-up, just select "'Start in Safe Mode"''
If it works in Safe Mode and in normal mode with all extensions (Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: "Firefox > Quit Firefox"; Linux: "Firefox/File > Quit")

Firefox crashes on certain websites.

Recently, I had a malware/virus attack on my computer from XP Anti-Spyware. There were many pop-ups from XP Anti-Spyware. Then later I lost connectivity to the internet. I used Norton Security Scan to get rid of the malwares and viruses. After using the scan, my Internet Explorer and Mozilla Firefox Internet did not work. At first the pages wouldn't even load. Then we contacted a Norton Security, who tried to remotely go through my computer to try to fix the problem. The technician rebooted my computer, reseted my internet, and also tried to reinstall Mozilla (safe mode) and Internet Explore. Well we were able to get both internets up and running. Only problem is that Mozilla crashes will work for a minute and crash or when on a certain website it will crash suddenly. I'm able to get on Facebook without it crashing. But websites like Yahoo, or when I search on Google, the internet crashes. I was not able to get on my email through Mozilla, instead I had to go through Google Chrome. Can you please help me please. Also, I removed Norton Security System, to have more mobility online. Thanks.

Kernel Panic with certain websites

Using OSX 10.3.9 on ibook 1.2 gig with 512 RAM. I have airport express, and am using a cable modem. This is a continuing problem with certain areas of sites (t-mobile, other wireless companies and random websites). I am using Norton Internet Security 3 for mac, which has given me few problems before, mostly lost connections.
So, I hit a site that is a problem, Safari (and Firefox) will try to load the page and as soon as I attempt to close the window, I get the kernel panic page telling me to restart. I've turned off the firewall and return to the same page, but get the same results. Here's my log:

Hi Christopher,
it appears that a kernel extension by Norton is causing these panics (no surprise here). Please uninstall Norton.

New MBPro and iTunes does not work along with certain websites on Chrome and Safari

I just bought my Macbook Pro 13" about two weeks ago. Everything worked fine when I was at school and at my friends house. The day I came home, I was not able to go to many websites such as Facebook.com or even my Gmail on Chrome or Safari. Also, the App Store does not load. I started using Firefox, and I am able to go on any website. Unfortuantely, the problem still exists with the App Store. Also, whenever I launch iTunes, it immediately freezes and I get the rainbow wheel and have to force quit. If I go straight to my music from Finder and click on a music file to play, it open iTunes, but freezes it and doesn't play anything. Can anyone at all help me with these problems?! I didn't expect to run into so many issues since my laptop is so new. I feel like it could have something to do with the internet at my house...

Is it possible your home router is blocking some websites? I used to help parents set up routers to block out certain websites so that their kids would stay pure and honest. Anyways, if all else is the same, and the variable is the router (home, school, friends house), then we have to blame the router.

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
*https://support.mozilla.org/kb/Safe+Mode
If images are missing then check that you aren't blocking images from some domains.
*Check the permissions for the domain in the current tab in "Tools > Page Info > Permissions"
*Check that images are enabled: Tools > Options > Content: [X] Load images automatically
*Check the exceptions in "Tools > Options > Content: Load Images > Exceptions"
*Check the "Tools > Page Info > Media" tab for blocked images (scroll through all the images with the cursor Down key).
If an image in the list is grayed and there is a check-mark in the box "Block Images from..." then remove that mark to unblock the images from that domain.
Make sure that you do not block third-party images, the permissions.default.images pref should be 1.
*http://kb.mozillazine.org/Images_or_animations_do_not_load
There are also extensions (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images.

The way websites render is out of your control. Try a different browser. Try making your viewing window larger or smaller as a possible work a round.
If you are truly using 10.4.11 as you indicate, more than likely your browsers are outdated version which may not be compatible.

Firefox lags with youtube and .gif images

Everytime I try to watch a video on YouTube or even on other sites FireFox lags aprox every 10 seconds. Is annoying. The same thing happens with .gif images.
How can I fix this?
== This happened ==
Every time Firefox opened
== Always

This can be a problem with session restore.
Firefox stores session data every 10 seconds to make it possible to restore a crashed session.
If you have (security) software that interferes with that or have many tabs open then that cause cause a delay.
Some have reported that increasing the session store saving interval worked for them.
See:

Why is Firefox communicating with China from the UK?

Hello there, I'm using a Firefox beta v13) and have had my firewall warn me that Firefox was attempting an outbound communication to IP 117.21.224.232. It's done this before (in prior versions too) and if I deny the connection, Firfox stops working.
I finally did a lookup on the IP and found that it's in China. Why is Firefox doing this and how do I make it stop? I'm rather worried.
Thanks,
Orbis

Have you tested in Firefox's Safe Mode to see whether it is caused by a custom setting or add-on?
First, I recommend backing up your Firefox settings in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, restart Firefox in [http://support.mozilla.com/kb/Safe+Mode Safe Mode] using
Help > Restart with Add-ons Disabled
In the Safe Mode dialog, do not check any boxes, just click "Continue in Safe Mode."
If you still get the connection out, you could also try disabling all update checking (Options > Advanced > Update > "Never check"). Does that make any difference?

Firefox 4 issue with certain websites and mp3s

Downloaded Firefox 4 for my Mac 10.6.7. I'm no longer able to watch certain videos (like those at adultswim.com) or listen to mp3s. Know this has to do with plugins, but I can't figure out which ones are the issue.

Hi Fred-
I tried your suggestion, and both the sites I mention above loaded without issue. But I think hardware acceleration was already off:
When I went into the advanced preferences in safe mode, hardware acceleration was unchecked, which, according to the FF guidance I saw on safe mode, is the default in that mode. When I then relaunched FF in normal mode, acceleration was still unchecked. So unless starting in safe mode turned off the acceleration and that setting carried over to normal mode, I'm assuming it wasn't on in the first place.
Because the issue only occurs on a few sites, I'm assuming it is sloppy web design as opposed to a browser problem. I wonder if the issue could be related to the problem sites using Java or Flash, or some script that stymies Firefox, but I don't know how to check that.
The thing that bothers me is that the browser causes the whole system to hang while it struggles with loading the site. I'm no expert, but I don't think that should happen in a four-core, 2.8 GHz system with 6 GB of RAM.
