[SOLVED] Firefox XPCOM

NeekO · 2009-02-20 11:36:19

Hey guys. I'm having a little bit of trouble here Yesterday,after turning on Arch and trying to launch FF, this message poped-up: Couldn't load XPCOM.
I've been googling around www, but found no answers nor help regarding this particular error. Before that FF worked fine and then suddenly crashed.
FF is my first-choice browser so i wouldn't like to change it to any other, that's why any ideas would be appreciated.
Thx in advance

Ok, solved that. It seems that some *.so files were missing from xulrunner main folder (dunno how they got lost), but anyhow, i found needed files in some patch,copied what was missing and wuolia

Could you please explain what exactly you did? Because I have now the exact same problem. Now when I build IceCat (with xulrunner-1.9.0.11) the package builds fine. But when I try to start the program it tells me that it "Couldn't load XPCOM.".

Thanks in advance.

I had this problem a couple of days ago with firefox and reinstallation of both firefox and xulrunner solved it.

Well, I can use Firefox 3.5 with xulrunner 1.9.1. But I want to run IceCat 3.0.11 and for that I need xulrunner 1.9.0.11. I have the old xulrunner file here and both worked in the past. But when I build and install the IceCat package now I get the above mentioned error message.

So did you actually try reinstalling?

I'm having this problem and I just reinstalled firefox and xulrunner:
pacman -U firefox-3.0.11-1-i686.pkg.tar.gz xulrunner-1.9.0.11-1-i686.pkg.tar.gz

My system is entirely up-to-date minus these two packages. Still getting "Couldn't load XPCOM." I'd upgrade to 3.5 if flash didn't crash it and if three of my plugins were supported. Thanks for your help.

What did you do to fix this?

I don't want to use ff 3.5 yet. My system is up-to-date except these two packages >>

I have firefox-3.0.11-1 & xulrunner-1.9.0.11-1

Well the thing is, when i started getting this error, i tryed launching xulrunner itself and got error about some *.so files missing ( can't remember exactly which ones, it was along time ago ). So i just found a rpm package of xulrunner version i was using at that time (1.9.0.9 or smth like it), extracted it and copyied missing *.so files to xulrunner's dir To tell you the truth, i think i remember that those missing files where actually in the original dir, but somehow xulrunner just couldn't make a use of them, so as i said, replacing them worked like a charm for me.. I hope it helps you too...

Thanks for the reply, I'll try that out.

You guys don't read. Simple reinstallation of xulrunner would have worked.

I read your posts telling us to reinstall, I've tried that, It might of worked for you it hasn't worked for me. I don't know why, Maybe you do, If so do tell, Posting reinstall three times isn't very helpful.

EDIT#1

OK had a look at this today, libjpeg.so.62 was the file missing. I made a backup of it before upgrading. Then copied it into /usr/lib/libjpeg.so.62

Now I don't get the XPCOM error, Not sure if thats a good way to fix it long term, But it works for now.

It never worked for me. Replacing missing *.so did the trick. As Coda said i too don't know if it's a good way to deal with such problems, but as long as it works i'm fine with it

This just happened to me. Hadn't updated Firefox in a while and after updating I was getting Couldn't load XPCOM error.

Had to update libevent and sqlite for it to work.

Just had the same problem, with xulrunner 2.0.1-1 and Firefox 4.0.1-1.
With a little digging...:

xulrunner
/usr/lib/xulrunner-2.0/xulrunner-bin: /usr/lib/libnss3.so: version `NSS_3.12.9' not found (required by /usr/lib/xulrunner-2.0/libxul.so)

Looking up NSS, I found out...

pacman -Ss nss
extra/nss 3.12.10-1 [1.37 MB] [installed: 3.12.8-1]
    Mozilla Network Security Services

After patching NSS (and nspr as it's a dependency) it worked.

So, re-installing ain't always the solution, looking up the problem is. Thanks NeekO for mentioning running xulrunner on it's own, helped me solve the issue as well.

Older thread, but just starting xulrunner helped me to track the error down, too. Thanks.
