Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

• Microsoft Safety Scanner
• MalwareBytes' Anti-Malware
• Anti-Rootkit Utility - TDSSKiller
• AdwCleaner (for more info, see this alternate AdwCleaner download page)
• Hitman Pro
• ESET Online Scanner

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one. Windows 8 has antivirus built-in already.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Hi Fred,

I had mentioned in my post that I already used Firefox in Safe Mode and it did not change anything. Crashing of both PC and Firefox continues. I also mentioned I already have run multiple antivirus programs, including MalwareBytes' Anti-Malware, AVG, and Comodo Cleaning Essentials and I do not have any virus and malware issues.

I can keep running malware programs but know this is not the issue. Any other ideas??

II have pretty much all antivirus software recommended in previous post reply, and then some. I am certain I have a “clean” machine. My machine continues to crash.

To be more specific, my PC resume vs restarts when I restart the PC. It always comes back to the current setting s I left it at. It seems likely that this is either a Flash or Firefox issue or both. Many times when going back to the desktop, it shows the “Flash has stopped working” message. When I check the Reliability Monitor of my PC, each and every time I’ve crashed, it says the “Plugin Container for Firefox has stopped working”. And I do have the latest version of Flash and Firefox installed.

I don’t see other alternatives as I’ve ruled most out. That includes bringing up Firefox in Safe Mode, updating drivers, etc. I really would like to keep both Flash and Firefox on my PC but I cannot continue crashing multiple times a day. It’s sooooooo frustrating.

Any advice what I could try next would be very much appreciated. HELP!!!

I've called the big guys to help you. Good luck.

I'm re posting the snapshot I took of my reliability monitor.

Thanks Fred. Appreciate you calling the "big guys". Eva

Two things to try;

Download Firefox Full Installer For All languages And Systems {web link} Save the file. Then;

Using your file browser, open the Programs folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Mac: Open the "Applications" folder. Linux: Check your user manual.

Look for, and rename any Mozilla and Firefox folders by adding .old to them.

Now run the full installer. If all goes well, remove the OLD folders when you are done.

Start your Computer in safe mode with networking. Then start Firefox. Try Safe web sites.

Starting The Computer In Safe Mode;
Free Online Encyclopedia

I tried both things.

1) I followed the instructions and did a new install of Firefox. I assumed my usual activities in Firefox where I have as a norm multiple tabs open. I proceeded to crash as I have been doing. When I start up again, I usually see an unresponsive script of some kind or that Firefox has crashed.

2) I have now been working in Safe Mode on my computer for several hours, opening Firefox and visiting the same safe sites as before. I have not crashed. I noticed that I did see the message that the Flash plug in has crashed in Firefox (see pic) but my PC did not shut down.

So will remain in Safe mode until I hear back... Thank you.

Please post all the latest crash reports.

If Firefox is working okay in computer safe mode, that means one of the other non-system programs is causing the issue.

Can you provide a list?

To be clear, I had no crashes in Windows mode, whether that means Firefox was OK or anything else, to be honest I don't know. Also to be clear, Windows doesn't completely shut down. I have to turn the PC back on and it goes into "Resuming Windows" mode.

To be clear, you want a list of ALL my applications installed on my computer?

Thank you. Appreciate your continued assistance

Both macs and pcs in our home are crashing because the plugin crashes. This has been just since the last update.

We cannot acces youtube or bluemountain cards, etc or many websites that have flash ads on them.

It's getting very annoying.

Hi gtrainer, The list requested would be the extensions list (FredMcd?)

However since the plugin container/Flash does not crash in Safe Mode, it is possible that hardware acceleration/another extension could be affecting the performance.

So in regards to 1, do you have the last 5 crash reports in the about:crashes page (paste about:crashes into the url bar of a new window and click submit, and copy the reports that start with "bp")

Also see http://mzl.la/14Ad7Md which recommends disabling hardware acceleration or reinstalling flash.

In reply to GadsdenGurl, just to be accurate, my Flash plugin did seem to crash in Safe Mode, however I did not have to restart my PC and go through my machine coming up in "Resuming Windows" mode. I'll double check that to make sure I got that right.

As requested, here are the first 5 crash reports:

Also wanted to note that I installed a new hard drive on my PC as I thought the errors I found was a possible cause of these crashes. It wasn't. Both before and after reformatting my hard drive, this issue persisted. So my machine has a clean install of Windows 7, all drivers are updated, and the Flash plug in is the latest version. I also removed the check mark from "Enable hardware acceleration" in Flash when reading up on this issue and is one of many different things I have already tried ;-).

Hopefully those crash reports can report the exact cause. All help would be most appreciated. Thanks!

Hi Eva,

On our PC this crashes the system.

On the Mac, just the FireFox browser..

I am going to be more careful about submitting reports to both Adobe and Mozilla when it happens.

I am getting sick of this. I've never had a Mac app crash like this! And I've been using since 1995.

The crashes are a problem with the Shockwave Flash plugin.

Did you disable protected mode in the Flash plugin?

• http://kb.mozillazine.org/Flash#Troubleshooting

You can set the Flash plugin and possibly other plugins to "Ask to Activate" on the "Firefox/Tools > Add-ons > Plugins" page.

You can uninstall the current Flash player version and (re)install the latest Flash version.

See this about uninstalling Flash players:

• http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html

Note that this will remove all installed Flash players.

You can find the latest Flash player versions for Firefox on this page:

• http://www.adobe.com/special/products/flashplayer/fp_distribution3.html

I've done all this.

The graphics drivers are for Windows correct? I turned off hardware accel. and reinstalled, already had the latest version. The fault lies in the CODING of the plugin, that much is clear.

You might want to talk to Adobe about this?

I wish I had KEPT my old version, the new version is the trouble maker!
