Firefox opens ok, but crashes when I open a web page

I upgraded Shockwave and Flash today, and since then, Firefox will crash when I open a web page. Firefox itself opens fine, but opening Gmail or Facebook causes it to crash with a windows error saying it has crashed.
Im using...
Firefox 4.0.1 on Windows 7
Flash player V10 plugin
Shockwave V11.6

This is very consistent, happens within minutes? In that case, I suggest this test:
To see whether one of your extensions is the culprit, could you test in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).
Any difference?

FireFox keep saying "unexpected error" when trying to print web pages.

FireFox keep saying "unexpected error" when trying to print web pages. The print preview works OK, but when you try to print that "unexpected error" jumps up.
Please email me on what to do to get FireFox to work.
I don't see anything in the FAQ that might help me.

Hi,
Please also try this setting: Windows start menu or Control Panel > '''Devices and Printers''', right-click the printer > '''Printer properties''' > '''Advanced''', and select '''Start printing after the last page is spooled'''. In this case you can also close Firefox after spooling is over (usually much faster than direct printing), and printing will continue.
Also as a general case, if you have security software (antivirus, firewall etc.) installed, you can try deleting all existing instances of Firefox and its related processes/files in all the different configuration modules/areas of the security software like process monitoring, sub/spawned process control, virtualization, HIPS etc., in addition to the security software's main configuration panel. Instead create new fully allowed/trusted rules for Firefox + its related processes in all the different modules/panels - a genuine/original Firefox installer as well as all the installed EXEs (Application) and DLLs (Application extension) are digitally signed by Mozilla Corporation (right-click > Properties > Digital Signatures). Even otherwise, some security software may also ask again when Firefox and/or its sub processes are started, and you may be able to allow/trust at that time. Please see [https://support.mozilla.org/en-US/kb/Firewalls this].

Just updated to the newest version of Firefox and it keeps crashing when I open the browser. I tried opening it with add-ons disabled and it still keeps crashing. Crash ID: bp-03b36d11-304e-4f80-ab9e-79b7f2111223

I just updated to the newest version of firefox for my mac laptop. It keeps crashing when I open the browser and does so even in safe mode. Laptop is about two years old. Might it be an issue with the OS? I have not updated to Leopard yet.

It seems that the problem is related to fonts.
(1) How were you updating your operating system ?
If you use *_Software Update_*, hurry up, download and apply the combo updater available from :
http://support.apple.com/kb/DL1361
but CAUTION, this update introduce a serious problem with some fonts. At this time the only workaround available is to reinstall 10.6 tyhen apply the combo updater 10.6.6 available from :
http://support.apple.com/kb/dl1349
(2) if you didn't used *_Software Update_*, run a maintenance tool like the free MAINTENANCE available from :
http://www.titanium.free.fr/index_us.html
Apply it to clear caches files, mainly those dedicated to fonts.
It would be also a good idea to check the health of your fonts with FontBook.

Firefox locks up then crashes when I open the Tools-Add Ons page

Hi - Just updated today with automatic 6.0.1 update and once I did, Firefox killed Adobe Reader. I fixed that but then found that opening the Tools, Add-Ons page locks up Firefox for a few minutes, then crashes it.

Hello Ted.
Although possibly not related to your problem, I will remind you that the version of Firefox you are using at the moment has been discontinued and is no longer supported. Furthermore, it has known bugs and security problems. I urge you to update to the latest version of Firefox, for maximum stability, performance, security and usability. You can get it for free, as always, at [http://www.getfirefox.com getfirefox.com].
As for your problem, you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.

Firefox 3.6.10 crashes when I open it, even after uninstalling, deleting the default profile and all user appdata folders.

I really have no idea why this is happening. I have a feeling it may be some sort of virus or malware but i've done scans and nothing has come up. Internet Explorer is working fine. I'm on Windows 7.

This can happen if adware Genieo is installed without your knowledge. Removing it will help,
1. Download and use free AdwareMedic to remove the adware
    http://www.adwaremedic.com/index.php
    Install , open, and run it by clicking “Scan for Adware” button   to remove adware.
    Once done, quit AdwareMedic.
               or
    Remove the adware manually by following the “HowTo” from Apple.
    http://support.apple.com/en-us/HT203987
2. Safari > Preferences > Extensions
     Turn those off and relaunch Safari to test .
     Turn those on one by one and test.
Note:
If you don’t have another browser installed,
startup into SafeMode, log into your account
and download AdwareMedic or the removal instructions from Apple.
Follow these steps to start up into Safe Mode.
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup sound, press and hold the Shift key. The Shift key should be pressed as soon as possible after startup, but not before the startup sound.
Release the Shift key when you see the Apple logo appear on the screen.
After the Apple logo appears, it may take longer than usual to reach the login screen. This is because your computer is performing a directory check as part of Safe Mode.
To leave Safe Mode, restart your computer without pressing any keys during startup.

What can plug in folders caused crashing of computer!

You need to put both the Project and the Event on the external drive. The external drive must be formatted for Mac (Mac OS Extended (journaled)).
All moves or copies should be done from within iMovie. For best results, use the Consolidate Media function described at the and of the post below.

Firefox crashes when left on a web page for NAS device

I access the GUI of a NAS device (QNAP TS-879Pro) from Firefox on Mac OS 10.6.8. It works great, but I notice that if I leave it on that page (a sort of visual OS front end to the NAS box), eventually it will crash (with me doing nothing - it just sits in the dock and I come back an hour later and I see the "Firefox has crashed" window).

Firefox on Linux crashes when loading java script web page while running on Windows works fine

Hello all,
well in my effort in writting php I frequently use phpanywhere.com
The site loads successfully in both Windows and Linux setup (fully up-dated). However, when I press on .php file so to begin editing the Linux installed Firefox crashes and closes down every time (also when using different preference under JacaScript menu). Windows setup seems to have no problem at all.
This has been checked in three different PC with Ubuntu Maveric installed on them. In all these cases Firefox crashes.
Any possible ideas on that one?

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.

Firefox constantly crashes when it opens and when tabs are changed.

Here is a screenshot of all the crashes since this started a week ago:

Any help would be appreciated.

One of the bug reports linked to your crashes says the HTTPS Everywhere extension could be a contributing factor. Would you try disabling it for 48 hours and see whether that makes any difference?
You can do that on the Add-ons page. Either:
* Ctrl+Shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Extensions.
Some of these crashes are related to the "Just in Time" (JIT) JavaScript compiler(s). You could try disabling some of those features to see whether that helps. Alternately, you could run Firefox in its Safe Mode for a period of time since that disables them automatically (but in that case, extensions also are disabled).
''To disable individual preferences:''
(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 above the list, type or paste '''javas''' and pause while the list is filtered
(3) Double-click the following preferences to switch them to "false":
* javascript.options.baselinejit.chrome (Firefox UI)
* javascript.options.baselinejit.content (page content)
* javascript.options.ion.content (page content)
There might be other relevant items but we're a little out of my depth here.
''If you prefer to test using Firefox's Safe Mode:''
You can restart Firefox in Safe Mode using
Help > Restart with Add-ons Disabled ''(Flash and other plugins still run)''
In the small dialog that should appear after Firefox exits, click "Start in Safe Mode" (''not'' Reset)

Windows 7 crashes when I visit certain web sites

I have been running Windows 7 64-bit Home Premium since it first came out. I have a HP Pavilion desktop with 8 gb of memory and 700 gb of hard drive. It has worked fine with no crashes since day one. Recently I got my first blue screen with a notice that the system had crashed and a "crash dump" was going on. I rebooted and the system started up again and I have no problems. Now it has happened six or seven times in the past month, most of the time when I visit an ESPN page where there is a video that starts whether I want it to or not. Usually while the video is loading is when the crash happens. One other time it started happening when one of my desktop applications (Weatherbug) was very busy updating itself; after a couple of crashes I uninstalled Weatherbug and now it only crashes when I go to ESPN. This can't be a problem exclusively caused by ESPN, I wouldn't think, and I suspect that if I went to more sites with similar video features it might happen again. But this has never happened before, so what has changed in the past couple of months that has caused my computer to crash so often?

Please Mention the website...
We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
#Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
#In that text field, enter %APPDATA% and press Enter. An explorer window should open.
#From that explorer window, double-click on the ''Mozilla'' folder, then double-click on ''Firefox'' and then on ''Crash reports''. Double-click on ''submitted''.
#Now, you should see a list of files that contain reports. Go to ''View'' > ''Arrange Icons by'' > ''Modified'' to get the most recent files at the top of the window.
#Open the most recent 5 files with a text editor and copy the IDs.
#Paste each ID into the reply window on the forums.
Thanks in advance!

My iphone 4 camera shutter won't open. I have already done a restore and I am using the latest iOS. The front facing camera works during FaceTime but crashes when I switch to rear camera. in Camera mode I can't switch to front camera.

My iphone 4 camera shutter won't open. I have already done a restore and I am using the latest iOS. The front facing camera works during FaceTime but crashes when I switch to rear camera. in Camera mode I can't switch to front camera. I plan on replacing this phone with an iphone 5s when it comes out but I need this phone to work until then.

When you did the restore, did you restore from a backup or restore as new? The final step of user troubleshooting is to restore as a new device, not from a backup. If you restore as a new device and the camera still does not function, it is probably a hardware issue. Make an appointment at the Apple Store Genius Bar and have the device checked by a Genius.

Why does Firefox crash when I open Adobe, Firefox & all plug ins including Adobe are up to date and current, WHY?

Firefox crashes when I open Adobe (pdf) ALL plug ins are up to date as is FF

This is a known issue with Adobe Reader, and it depends on Adobe updating their plugin.
Whilst you're waiting for Adobe to fix their plugin, you can disable it and fallback to the default PDF reader in Firefox by following these steps:
#Go to ''Tools'' > ''Options'' (or ''Firefox'' > ''Options'').
#In the Options window, select the ''Applications'' tab.
#In the ''Search'' field, type ''PDF''. You should find ''Portable Document Format (PDF)''.
#On the right handside you should find an ''Action'' column. In order to view PDF files in Firefox, choose ''Preview in Firefox''.
Did this fix your problems? Please report back to us!
Thank you.
