Firefox is crashing when loading specific pages.

I've tried disabling and re-enabling each plugin, I've downloaded the newest version of Firefox, and ''nsBrowserOpt.dll'' doesn't seem to be the problem. My computer recently (like two hours ago, haha) crashed and rebooted using Microsoft System Recover with a recovery date of February, if that has anything to do with it--prior to the computer crashing, Mozilla had a lot of hang-ups, but no crashing. I suspect malware, but I'm really not at all sure, because Norton keeps coming up with that little window that says "A recent attempt to attack your computer has been blocked." which is slightly unsettling. But I don't know where to go from there.
I'm really terrible at computers.

Firefox crashes when loading certain pages. ID: d9839212-23dd-4214-94a1-8a7db2100704

Firefox crashes when loading certain pages. Often pages with video content
== Crash ID(s) ==
ID: d9839212-23dd-4214-94a1-8a7db2100704

The crash reports indicates the crashes may be caused by a file named mcbrwctl.dll, that file is part of McAfee Site Advisor. Try disabling the McAfee Site Advisor to see if that stops the crashes.
To do that, in the Tools menu select Add-ons to open the add-ons manager. Select the Extensions panel, then in the list of extensions select McAfee Site Advisor then click on the Disable button. Re-start Firefox to complete the process.
For info McAfee Site Advisor has caused various problems with Firefox for quite a few people.

Firefox 4 crashes when loading pdf and other sites unless I first open it in safe mode and then revert

So firefox 4 crashes when opening in-browser pdfs and a whole host of other sites, even with no addons running.
I've found a fix: start in safe mode, then close and open in normal mode. This always solves the problem.
But '''why?''' What is causing this incredibly annoying problem. I went from happily browsing at high speeds (firefox 3.6) to suddenly finding myself propping my head on my arm, looking at a jammed firefox, trying not to go crazy, for about 2 minutes until it unjams (for pdfs - for the other sites it doesnt unjam) - and the pdf page ends up just black. God forbid I press F5 again lest I want to relive the experience.
This only happens on my work laptop. It's a top of the line laptop. It connects via a remote VPN. I'm not sure if that's relevant but I'm trying to give as much info as possible.

1. You have a pre-release Beta 1 version of what will become Firefox 4 in like 5 or 6 months. Unless you are intending to test it for flaws and report those flaws to help in the development process, don't use it.
2. Did you create a new Profile for 4.0b1, and are you using that Profile with it? ''That isn't done automatically when you install 4.0b1, and those of us who have been doing the "testing" for many years consider a new Profile as the basis of doing out testing.''
[http://support.mozilla.com/en-US/kb/Managing+Profiles]
IMO, Mozilla is making a huge mistake by directly offering these beta versions to the general public.
Also IMO. if you want to play with 4.0b1, use the Portable Firefox 4.0beta version to minimize any conflicts with a currently installed version of Firefox, and to eliminate the need for creating a new Profile for 4.0 Beta #:
Download Firefox Portable Test to your hard drive and double click the '''FirefoxPortableTest_4.0_Beta_#_English.paf.exe''' file. The entire installation (including a new Profile for "Portable") will be self-contained in the \Program Files\FirefoxPortableTest\ folder and won't interfere with an "official" version that you already have installed. Your Profile will be in the \Program Files\FirefoxPortableTest\Data\profile\ folder.
The "down side" is that Firefox Portable won't launch if any other version of Firefox is already running.

My firefox browser closes when loading any page without a crash report

My broswer keeps closing when loading. No crash report pops up, it just takes me to the "well this is embarrassing..." page that asks if I want to restore, to which no matter which option I pick it keeps closing on me.

clearing cache, and cookies only removes the cookies and clears the
cache/ Not passwords or anything else. Closing in safe mode? That tells
us something. Now do this, 
1) '''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]''''' 
2) '''''Firefox > Add-ons > Plugins'''''. Disable '''EVERYTHING''' ! !
If Firefox closes on you, start it again and keep going. After everything is
disabled, restart in safe mode again. And let it sit for a while. 
3) Look at the list of programs below and run at least 3 of them. Each
program works differently so what one may miss another could pick up.

Firefox crashes when loading local pages (localhost)

Firefox crashes when I load local pages. This includes pages served by my apache server / localhost (WAMP). It also hangs when I load pages from complete websites that I have downloaded.
I was running Firefox 6 and upgraded to Firefox 7 before I discovered what the cause of the problem was. Downgraded to Firefox 4 and still had the same problem. Does anybody know how to fix this, developing with Chrome is driving me mad!!!???

Hello Xircal, thank you very much for replying.
I have tried to perform a standard diagnostic. Everything seems to run fine in Safe mode. Disabling Hardware accleration makes no difference. I can't check anything else because whenever I try to open Add-on manager, Firefox crashes.
I reinstalled again, just in case, but it's still happening.
Is it significant that the 'Update' buttons of the two outdated plugins won't work when I click on them?
Thanks again!

Firefox crashes when loading any page with flash. I have tried all available fixes including plugin updates. If I disable flash the crashes stop, but no flash.

Firefox crashes on any page with flash. I have the most recent version of Firefox on OSX Snow Leopard. I have made sure that I have all the most recent plugins and extensions and I am not running any custom theme. I have completely un-installed and re-installed Firefox and flash to no avail. I think the problem is in some user preference, but I cannot seem to find it. If I log out and use a different user on my machine, Firefox does not have the flash crash problem.
== Crash ID(s) ==
??

JYOuyang: I have the correct plugin for Flash. My problem is not the "Flash crashed" icon, which would be generally acceptable, but FIREFOX crashing, usually rather dramatically. I have since regressed to Firefor 3.6.3. I am still using Flash 10.1, the newest version. This no longer causes Firefox to crash. Now then -- if the same plugin causes no crashes in the new version of Firefox and does cause crashes in the prior version, it is not exactly a humongous leap to conclude that maybe, just maybe, there was a bug introduced in Firefox 3.6.4? I mean, it's not as if a major feature of 3.6.4 was a significant change in how plugins interact with the browser or anything... oh, wait, there was, wasn't there? Hmmm. Saying "It's Adobe's fault!" rings a little hollow when the 10.1 plugin works correctly in the prior version of Firefox. Any kind of host/plugin model relies on a contract between the host and the plugin, and when there's a crash, it indicates one side or the other broke that contract. Under the circumstances, it's difficult not to suspect the blame for this lies on the Firefox side. It's certainly possible that Adobe's code IS broken and the problem is that it SHOULD work with the new version of Firefox, if it were properly written, but it's not, so it doesn't. However, no one seems to want to dig down to find out or provide a workaround other than regressing to 3.6.3, so that's what I've done -- Firefox does too many other things right for me to switch browsers at this point.

Firefox crashes when loading some pages I have looked at plug-ins and themes as the problem but I do not have any of the ones that are listed as causing problems.

Recently I downloaded some up grades for my computer and now FireFox crashes when I try to change pages on web sites. It crashes in financial sites, my earthlink email account and a business web site I manage.

Thank you for the replies. Everyone was correct about the jack, interface, and phasing problems. I have been unplugging my motu audio interface and then using headphones at work. I have not changed any detailed audio output settings in logic. When I read that the jack might be a problem I tried switching headphones. This actually helped. I am using dre-beats headphones and they seem to be having issues with the mac/jack-(the phasing/panning problems. I can use these headphones with other devices but not the mac. I have to use ipod ear buds and the phasing seems fixed. Hopefully this information is helpful to someone else.
If anyone knows how to correct this issue please let me know its difficult to know what my final mixes are going to sound like and I have had to keep bouncing everything into i-tunes- sync to ipod and then listen in my car radio.

Firefox consistently crashes when loading Flash sites

For a couple of reasons I decided to go ahead and install OSS a few days ago. On the first day, the install went smoothly and everything was working just as it should (I used the oss-linux-free PKGBUILD in AUR). Yesterday and today, however, I've started to get a reoccurring problem that is, to put it lightly, driving me nuts.
Firefox (or Epiphany, though I prefer the former) consistently crashes when opening up any site that uses Flash or Java. With the way the internet is going, this is a large chunk of websites—not being able to visit YouTube or the website for Enemy Territory: Quake wars, for instance, is driving me nuts.
Now, when I say "consistently" I don't mean each and every time. I've been able to get these sites to load a number of times, but in the last two days Firefox has crashed in probably 2/3-3/4 of the time when loading any site that has a Flash element. I've made sure that I have not wrongly assumed this has to do with my newly installed OSS by uninstalling, reinstalling the kernel and all ALSA packages, rebooting, and then surfing the web for a while to see if anything went wrong. It didn't.
So my question is this: why is Firefox crashing so often in the two days since I've installed OSS? What can be done to rectify this?
After some experimenting, it seems the problem is worst under the following conditions:
- Having several tabs open, though not necessarily several tabs with Flash
- Listening to music and THEN navigating to YouTube or something.
However, it's not specific to these circumstances. In fact, just before I decided to make this post I opened Firefox, went to a site with Flash on it (one tab), and it immediately shut down. I tried this three or four additional times and was met with the exact same results.
Other info
Firefox: Pre-compiled Mozilla i686 build, v. 2.0.0.11
OSS: OSS (GPL version) 4.0, build 1012
Operating System: Arch Linux 2.6.23-ARCH
I've also posted this here.

I have the same problem. I've never been able to identify when it started. Once firefox crashes, mpd, if it was playing, becomes unresponsive. The only way to get a flash site working again is to reboot my computer.
I uninstalled flash: I'm not going to put up with that kind of behaviour. Now I watch youtube videos on other people's computers --you know how they say "You've GOT to see this movie!". And if I really need to see that one specific video, there's youtube-dl.
Unfortunately gnash doesn't work on youtube for me.

Safari opens but crashes when loading any page

I recently upgraded to Safari 6.0 (7536.25) on Lion 10.7.4. Now Safari opens but crashes as soon as I try to load a page. I've tried most of the fixes that I could find in the recent posts:
different pages to be sure it isn't page specific
disabled all extensions
renamed the extension folder so it wouldn't be accessible (even though all were disabled)I noticed that Safari recreated the folder still with all extensions disabled but just in case I clicked the Off switch at the top of the Extension list
renamed cache.db to get a new one
renamed webpageicons.db
Reinstalled Safari from the link in one of the forum posts
Please help!

I forgot to include the crash report info:

InDesign crashes when loading master pages

Having a problem loading Master pages, document is saved from CS3 to CS5 then when I try to load master pages from a different CS3 document InDesign crashes any ideas?

Does it work any better if you save the other doc as a CS5 file (use a new name -- don't overwrite CS3 files becasue you can't go back easily) before loading the pages?
It often helps to export the CS3 file to .inx, then open that in CS5 instead of the .indd.

Firefox sometimes freezes when loading new pages

I have had an issue for several months now & any help with it would be gratefully appreciated.
Quite often, when loading a new page, Firefox will hang for up to 30 seconds; the loading circle in the left hand corner of the tab will freeze & I will be locked out of the browser. That website's usually then fine for the rest of the session, but if I close and reopen Firefox the same thing will happen again.
I have tried other browsers such a IE, and the same thing also happens there. My laptop is becoming quite claggy in general, but I'm hoping I can at least find a solution to this!

Do you get a dialog saying a script is running slowly with Stop/Continue buttons, or does the problem just clear up without any messages?
Two other thoughts:
(1) To diagnose a possible Flash issue, you can switch the Shockwave Flash plugin to "Ask to Activate." The page should load the non-Flash components first. If it's just as slow, then we can rule out Flash as a potential culprit, but if it's much faster, that would be useful to know.
You can make the change on the Add-ons page. Either:
* Ctrl+shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Plugins. Then use the drop-down list for Shockwave Flash to select "Ask to Activate."
Sites that use Flash will generate a notification icon on the address bar, and either a link will appear in the black rectangle where you normally get videos loading automatically, or an infobar will slide down between the toolbar area and the page.
(2) About 8 months ago, a user with an enormous font collection discovered that when visiting pages that use downloadable fonts for the first time during a session, Firefox would hang for 3 minutes. ([https://support.mozilla.org/en-US/questions/957111 Firefox hangs on Websites (example: g2play.net)]) I don't know whether this is still a problem, but if you have tons of fonts, as a diagnostic, you could temporarily disable downloadable fonts.
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box that appears above the list, type or paste '''gfx''' and pause while the list is filtered
(3) Double-click the '''gfx.downloadable_fonts.enabled''' preference to switch its value from true to false.
I say temporary because many sites now use fancy fonts to display little icons instead of using images. With downloadable fonts disabled, these icons turn into tall rectangles with two rows of two characters (in other words, useless).

Firefox 9 stalls when loading static pages, how do I fix it?

Windows 7 Firefox 9 beta worked fine up to about three days ago, now stalls loading static pages. Seems like Foxnews sites in particular. Have cleared caches and cookies. disabled realplayer with limited improvement

Try the Firefox SafeMode. 
''A troubleshooting mode, which disables most Add-ons.'' 
''(If you're not using it, switch to the Default Theme.)''
# You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
# Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. 
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one.
