Firefox load crash

[urup]

A little update:

The above works only for one or two loads of the program.

I think a found the problem.
Forget the above post, and just out comment the last line of the prefs.js file, like this:
/*
* user_pref("update.lastUpdateDate", 1375609856);
*/

Great work @urup!
Now I got running my Firefox 0.9 again.

Does anybody know what's the exact meaning of
user_pref("update.lastUpdateDate", 1375609856); ??

Bye!

Would someone please me so kind as to put that fix in laymans terms?

Worked here as well, if anyone encounter problems after the change, it would be nice hearing about it.

Yes, since you asked so nicely

1. Go to your the directory: "C:\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Profiles\<firefox profile>
My path is: "C:\Documents and Settings\Mark Urup\Application Data\Mozilla\Firefox\Profiles\default.haw"
("Mark Urup" is my username on windows, so your have to look for your own username.)
The folder "Application Data" is a hidden folder, so make sure you have turned on "show hidden files and folders" in windows.

2. Open the file "prefs.js" in notepad (right click on the file and select open with, and choose notepad)

3. The last line should read "user_pref("update.lastUpdateDate", 1375609856);" (without quotes)
Change this to:
/*
* user_pref("update.lastUpdateDate", 1375609856);
*/

4. Save changes and close notepad.

5. Start firefox, and enjoy

Bug 247284 covers this issue.

Though the directory is called "default.zxu" instead of "default.haw" on my computer

I have the same crash symptoms with two seperate WinXP SP1 machines - without flash installed. I was able to revert to 0.8 with no problem on both.

I had the same problem until I added the fix from urup. I also found something else that I don't think anyone else has mentioned in this thread.

If I started an instance of FireFox using the "rapid opening" trick I could read this in the JavaScript console:

"Error: aDS.GetTarget(app, this._ncR(aProperty), true) has no properties
Source File: .../components/nsBackgroundUpdateService.js
Line: 190"

That message disappeared after adding the fix from urup, so it's most likley a related error. Maybe this has something to do with the root of the problem...anyone with enough scripting experience might find it interesting?

It's definitely a problem with the profiles. I wiped the profiles directory and now everything's moving along dandy. But for how long? It seems likely that the bug somehow corrupts profiles, which then makes firefox crash on startup. This needs to be fixed. Quickly.

Windows XP SP2 beta. I did the trick with commenting out the last line and it works perfectly now. This is definitely a bug that needs to be fixed. And what was with that Netscape pop up anyway. As SOON as that popped up, I began to crash constantly. That and I couldn't find .8 anywhere to reinstall that so I'm, UGH, using IE right now to post this since I just GOT Mozilla working.

Created an account here just to thank you Urup. Great fix! ^.^

I'm suffering from the same symptoms.

One other problem. Now Yenc PowerPost crashes on start up...

Thanks Mark!

I'd like to know the cause of the problem. It has to be more than the quick fix to the prefs.js file.
