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.

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 crashs when visiting any page with flash content, how I can I stop that?

HI all,
Any page I visit with a flash video of some sort causes firefox to lockup, youtube is just the most prevalent. The page loads, then the program compatibility assistant pops up. I can't download,cancel or close out of that window and I have to ctrl-alt-delete and shut down the plug in container manually to be able to continue surfing. I have tried all three options on the firefox support page, tried using both 3.6.6 and 4.0 Beta 1, updating flash, no joy on any of those attempts.
I can play videos using VLC normally and the video that starts up when I visited the 4.0 beta welcome page works fine if that helps any.
Can anyone help?

If you close Firefox, then start Firefox in Safe Mode, does the problem still occur? For instructions on starting in Safe Mode, see [[Safe Mode]]. Or you can try creating a new profile. Your Firefox settings and info are kept in a folder separate from the Firefox program, called your profile folder. Try creating a test profile, to see if the problem still occurs. See [[Managing profiles]]. Also it can be a extension or plugin causing the problem. Extensions can sometimes be the cause of problems. If the problem does not occur in Safe Mode, then you can disable your extensions one-by-one until you find out which one is causing the problem. See [[Troubleshooting extensions and themes]]

When loading any page with Flash content Firefox will always crash. Any Ideas to fix this?

The issue occured following upgrading to 3.6.13 from the previous version.
Firefox will not crash if the Adobe Flash plugin is disabled. I have uninstalled and re-installed Flash player & Firefox, both of which did not solve the problem.
The issue is not present within the latest versions of IE, Chrome, Opera or Safari.
Any help to possibly solve this problem would be greatly appriciated?

After updating firefox today to 6.0, firefox is unable to load multiple tabs at the same time. When I try, firefox refuses to load any pages, and instead is stuck trying to connect to each page.

After I updated firefox to 6.0 today firefox has developed a problem loading multiple tabs. When I try to load 10+ tabs, either at the same time or by opening each tab separately, each tab is stuck trying to connect to the desired page. This continues if I close all the tabs and try to load a single page, the single page is unable to get pass connecting. In order to load a new page when this situation arises I must close down firefox and start again, and the program has no history of the previous session.

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!

Firefox crashes when loading certain pages. 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 becomes really slow then eventually unresponsive when loading a page with many hires images. Unsual high memory usage up to 2gigs just for firefox. Was never a problem with v3.6.

When loading a page with many hires images, Firefox becomes really slow and scrolling becomes jumpy then eventually becomes completely unresponsive. Unusual high memory usage of up to 2gigs just for firefox when loading these pages. This was never a problem with v3.6.

I encountered the same type of problem. Firefox running terribly slowly and slowing down my entire machine (Core i5 with 256GB SSD). Searching the forums, I found a couple of things about troubleshooting performance issues, one of which was to use '''hardware acceleration''', that is on by default. It was turned on on my PC, '''so I tried deactivating it, and it worked!'''
So doing the exact opposite as Mozilla support said solved the problem. It is really a pain now to work with Firefox. I'm using it because I have no choice, but I'd recommend IE and Chrome over Firefox... Whatever, the market will decide once Firefox has become to crappy...

Firefox doesn't load any page after a while.

I'm having problem with firefox while surfing after a while. For example at first 15 minutes , there is no problem , after a while firefox doesnt load any page , i have to close it and reopen it again to make it work. While firefox is not loading , i can use other browsers as normal. It just doesn't load any page at all but the program itself responds so I can close it with X button.What could be the problem , I'm using latest firefox.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

My PC repeatedly asks for authorization when opening I-tunes library (wont let me play tunes), have tried ALL the suggestions to remedy authorization but to no avail.

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 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.
