Do you have any compatabilty problems using Firefox alongside Mcaffe

[AnthonyG]

Hi for about a month now i have been having this major problem with Firefox and that is it crashes intermittently and then causes no other browsers to work after the crash until i restart windows, this includes I.E Opera and Maxthon.

I then when i try to shut down windows have an error consisting of xpcom:eventreceiver which contues to come up about 8 times until the machine will switch off. Which is what caused the crashing of firefox.

I have read around and everyone doesnt seem to have a clue what it is (although it occurs quite frequently), but the consensus is it is a compatability problem with firefox and mcafee (i use mcafee virusscan home 9).

So i am curious do any other mcafee users who browse with firefox have this problem also. So thought a poll would be best way to achive any answers. I wasnt sure on how to actually construct a poll so this text version is the best i could do.

Thanks for your imput

p.s if you have any advice on how to fix my problem my post asking for help is here

Do you use McAfee Firewall as well? or just the virus scanner?

I use mcafee av with firefox for quite a while and also used mcafee firewall for a while with no problems

I used to use mcafee personal firewall but switched to outpost back in september. I use no other mcafee products other than the virus scanner, (except that annoying security center).

The problem seems to have started back in early december/late november the same time i switched from Mcafee virus scan enterprise to mcafee virus scan home.

Here is the only topic i can find on it on the mcafee website

I have (today) switched back to MVE and i hope this problem does not come back.

[jkoppelm]

I get the same error, and I am using McAfee VirusScan (only) as well. The error dialog happens consistently whenever I close FF. Very annoying.... would love to hear if anyone has found a solution.

[Green Unrevolution]

I have this problem all the time. I didn't realize it was a problem with McAfee and Firefox. I have McAfee Security Suite.

[bmdenver]

Same problem here. It's finally got frustrating enough that I'm looking for a solution. I use Firefox 1.0 and McAfee Internet Security Suite 6.

[Jimbob1989]

I am using...

Mozilla FireFox with Mcafee VirusScan Enterprise 8.0.0 and Mcafee personal firewall plus with no problems at all.

Firefox is owned by netscape. I installed firefox 12/26/04, already had mcafee firewall and viruscan. This happened 2/19/05(after mcafee updates with no problem):
"We have detected that your primary browser is Netscape. McAfee Application
requires a one-time installation of the McAfee Clinic Activator Plug-in to
support Application installations and updates".

Reply from McAfee Consumer Online Support:
Our online services use ActiveX Controls, a technology that allows our online applications to interface with your PC through a browser. FireFox does not support ActiveX technology. Netscape also does not support ActiveX technology but by installing a plug in for it, we can use Netscape browser with McAfee softwares.

[allezgaulle]

same probleme with firefox : XPCOM:EventReceiver and the machine refuse to stop
my firewall is outpost

[Acadia]

McAfee 9.0 and Firefox with no problems but I made sure that my IE settings are what McAFee recommends. I never use IE but it is still set as my default browser; McAFee needs IE with the proper settings in order to update but you can, well I can anyway, use FF all I want.

[Mewnew]

Same problem here. Using FireFox and Outpost Pro 2.5. The problem seems to be related to McAfee and Outpost combined with Firefox, but.. any solution? This is driving me nuts. Had no problem with this before i switched from Kerio PF to Outpost.

[srv]

FYI....... I am running XP-Pro with Firefox 1.0, Norton AV 2005, and Zone Alarm 5.5.062.011

SAME PROBLEM

XPCOM: Event Reciever error on Windows shutdown.

HOWEVER, canceling out, albeit 4-6 times, seems to allow XP to complete shutdown.

[CarryStress]

I just recently started having this problem. I had been using Firefox and McAfee (Just Anti-Virus and Virus Scan) without a problem. I didn't get the error until I started using Mozilla's Thunderbird. I'm going to check into that.

[Katarsis]

Same problem for me except that I use ZoneAlarm 5.5 along with Firefox 1.0.
No McAfee products but Norton Antivirus 2002.

Randomly the browser wont show up at startup even though it appears in the taskmanager; in this situation I hit restart, but XPCom:EventReceiver wont shutdown and I must kill the process.

[leeco]

Hello all. I came accross this site when i was looking for imformation on xpcom event receiver. I never use any mcaffee products but i do use firefox with outpost firewall. When i'm using firefox, a while back it kept stopping to work on the internet as soon as outpost reported a loopback attack, then outpost would stop firefox from working. I was using f-prot av at the time but decided to change because i was sure i had a trojan. Sure enough there were two which avg found. once these were clean i had no more problems.

[christyxx1971]

Firefox 1.0.1 with AVG gives me the same trouble. I reported it some time ago to Mozilla but nothing has been done. It seems to me it's a Firefox issue that is independent of the type of AV that is being used.

[Noble_Bleu]

Hey Ya'll, Same prob here, running outpost, firefox, thunderbird, ms antivirus, BUT I don't have any MacAffee products installed. Also i get no load'n with any browser, i can see that it started the app in the process menu but no window as well as with IE and even still when i try to get out using an explorer window, could be specific to my probs with ISP, they haven't been keeping a stabil connection.

I am thinking it's between firefox and outpost, did a little diggin found this http://www.outpostfirewall.com/forum/archive/index.php/t-12546.html may help...

Found this one as well i DO have MS antivirus (knew i shouldn't have trusted them...) http://forums.mozillazine.org/viewtopic.php?t=228441

[E.T.]

McAfee won't even admit that Firefox exists. And, YES, there are problems that McAfee support won't admit to or give you good answers to. Microsoft, of all people, knows about the issue and suggests removing McAfee. No, they didn't try to sell me another product, just fix my issues.

On a funny side note...
1) I was using McAfee AntiVirus when I called McAfee support and they told me it looked like I had a virus... then...
2) I was testing out McAfee AntiSpyware at the time. One of the McAfee techs said the problem was spyware on my PC and to use WebRoot SpySweeper to clean it up... she didn't know that McAfee made a spyware product... I almost fell out of my chair laughing!

[carrot]

I have mcafee security suite and firefox. the same problem with the "XPcom event receiver" error. it mainly happens when i try to watch a .wmv, or .mpg, or open .pdf in the firefox browser (instead of downloading the files and opening them separately). any solutions out there?

[tuatara]

How about testing with Firefox 1.0.2 ??

Same problems ?

BTW i had no problems with Firefox on one of my systems in combination
with:

NOD32,Sophos,F-prot,Kaspersky,Kerio Fw,Tiny Personal FireWall,AVG or Outpost Fw etc.
i have a license of the mentioned software (will test it).

[bigc73542]

I am currently running McAfee 7.03.6000 and I have firefox 1.02, netscape 8, opera 7.54u2 and IE 6. There is no conflict between any of them at all.

I started to get the same error after installing Firefox 1.04. Firefox guys are telling me that is a driver problem.

[byancna99]

I was getting the same XPCOM: event receiver error. I have firefox 1.01, outpost firewall and avast antivirus. I thought it was outpost so i tried other firewalls but kept getting the same error. I took off avast and went with trend micro for the antivirus but left on outpost and firefox has been working ever since.

You should update your FireFox to the latest version. Several security problems have been fixed.

[MadMax33]

i believe this xpcom prob started after i installed sun java crap...i installed both updates....all though i have now uninstalled it, i am still getting the problem....i guess it has left something behind. i have mcafee security center, and firefox.

[Redbaran]

I have been having the same problem. The XPCOM:EventReceiver would lock after awhile with firefox only after I had been using firefox for awhile AND doing alot of heavy surfing, i.e. many windows open. Then, just recently, I installed eMule and I would leave my computer on over night and by morning, no more internet and I'd have to do the reboot. The breaking point came today when I tried to check my mail with Thunderbird and the stupid XPCOM would give me problems, every time, even after 4 reboots! I've never had problems with Thuderbird and XPCOM (I just installed it a couple days ago) until this email which was the first that I've gotten with Thunderbird and a ZIP file attachment.

So, after coming upon this thread and seeing that it seemed there is some problem between McAfee and Mozilla products, I shut down all of my McAfee stuff: Virus, Firewall, and Privacy Protection. Then wham! my email worked again. To me, this seems to confirm that it's a McAfee Problem. I haven't expirimented to see which part of McAfee is the problem, but if anyone figures it out, let everyone know.

[Yotian]

i am having the same problem my security setup is as follows, Sygate Personal Firewall home, Avast antivirus Home, Peerguardian 2

[JL_COG]

have the same prob ... running avg not mcafee

bigc <-QUOTE}

I'm right here with bigc. There isn't a compatibility issue between McAfee and Firefox on my end, and I've used both for several months now.

It could very well be something as simple and as silly as a plug in.

Firefox crashed on me the other day because I went to http://www.nfl.com and the page required REAL PLAYER plug ins to view a portion of the page, and I had the plug ins but DID NOT have Real Player installed on my machine any longer. Once I deleted the Real Player plug ins from the Firefox folder, I could surf to nfl.com and every other wsite without any problem. But until I did that, the browser would crash every time I tried to visit that page (with Microsoft's "Dr. Watson" error reporting message wanting to report the error)

[turbinespaul]

I have never installed Firefox but have had the same problem with Thunderbird 1.06. I don't use Norton or McAfee. I use Clamwin and the Windows XP firewall.

Problem went away after I uninstalled Thunderbird and then deleted the "Netscape" entry in HKEY_LOCAL MACHINE/Software. I then reinistalled Thunderbird 1.06 and have not experienced the problem again.

[Guy]

Same Problem Here!! Mcafee + Firefox = XPcom Event Receiver Problem :-(

[rechord]

I THINK I'VE SOLVED THE PROBLEM!! :D

It's a clash between Firefox and Microsoft .NET framework 1.1, so it seems.

Just uninstall .NET 1.1 using Add/Remove programs and see how you go.

Hi,
Here's what you can try. Download the following:
URL http://download.mcafee.com/molbin/shared/plgsetup/en-us/06202003/plgsetup.exe
and save it in a folder. Then right-click the downloaded file and
extract the contents. One of the extracted files will be
"NPMgWrap.dll". copy this file to the Mozilla Firefox/Plugins
folder in "program files". Make sure Firefox is not running at the time. Then update McAfee as usual. The update will run normally, except that the main browser will be Firefox and the update popup window will be a IE window. But this does not matter. All went well for me.
Bye. 'Mail me at mathewpdsa@yahoo.co.in' if this helps you.

hi there, i only registered to tell everyone what i found out about this XPCOM error... i got the same damn thing happening, but i dont have McAfee, all I have is Mozilla Firefox 2 BETA 1

in the Mozilla program folder there are 3 XPCOM files:

xpcom.dll
xpcom_compat.dll
xpcom_core.dll

to fix this error and keep firefox running all you have to do is move xpcom.dll into another folder or into a ZIP archive, but to make sure it is not in the directory that you found it in. after doing that, the error will stop and you can still use your firefox

please note though that I did this in the firefox 2 beta 1 program... i dont know if it works in different versions!
