Talk:Browser will not start up

From MozillaZine Knowledge Base

Do not ask questions here. Try the MozillaZine Forums instead.

FYI, in FF 1.0.3, when in safe mode, one can't disable extensions; one can only delete them - 'Disable' is itself disabled. (I find that, anyway; the Options button is greyed out (and 'Disable' is grey in the right-mouse menu), but Uninstall and Update are available.) My guess: if this is a new bug, a bug needs filing/fixing, if it's an old bug, the dox need changing.


Mozilla Suite (Windows) fails to start

I added this section because the problem is still being posted to the forums, for example, Mozilla 1.7.8 won't start (Posted: Wed 6th Jul 2005) and Mozilla won't open! (Posted: Tue 15th Mar 2005). Alice 16:27, 17 September 2005 (PDT)

Windows-specific problems - Windows Vista

On Vista, the Start -> "Run" box is not shown by default. You can use the "Start Search" box instead. See and

...Apparently Start -> Start search -> %appdata% does work. It's mentioned here as working on Vista. See also Alice 18:44, 2 March 2007 (UTC)

"The program must close to allow a previous installation attempt to complete. Please restart." on Vista

This is bug 369221, Vista only, fixed on trunk and possibly will be fixed in The same message was given in bug 283680, all Windows, fixed in 1.0.1. Since 1.0.1 is a long time ago, I'm dropping references to that fix.--Np 17:52, 18 May 2007 (UTC)

The Firefox bug fixed in 1.0.1 is bug 283680 I fixed your link. Alice 11:05, 20 May 2007 (UTC)

Faulty installation

The article mentions "JS_DHashTableOperate could not be located in the dynamic link library js3250.dll" is cased by a faulty install, could a bad install also cause this:

"The procedure entry point ?ListenerDied@nsCategoryObserver@@QAEXXZ could not be located in the dynamic link library xpcom_core.dll"

If so, perhaps we should rename that section to something less specific.--name already taken 06:50, 1 July 2007 (UTC)

If the solution to the xpcom_core.dll error you referenced also turns out to be a clean reinstall of Firefox using an official installer (which is the last step in the standard diagnostic advice given in the forum thread) then I think we should add a new section and maybe mention specific startup errors that point to a faulty installation. In any case, I think that the current JS_DHashTableOperate section should be removed since the underlying bug appears resolved (see below). Alice 16:54, 1 July 2007 (UTC)

JS_DHashTableOperate section

Here is what that section now says:

"JS_DHashTableOperate could not be located in the dynamic link library js3250.dll"

If you attempt to start Firefox and receive the error, "The procedure entry point JS_DHashTableOperate could not be located in the dynamic link library js3250.dll", it indicates a faulty installation caused by upgrading from an earlier Firefox version without exiting all firefox.exe processes. Uninstall Firefox and install the latest version from[1]

I reviewed the bug report, and in it, on 2007-01-12, Robert Strong stated in comment 17, I believe this was fixed by bug 357922 as comment #13 ... resolving -> wfm. If you look at comment 13, 2006-12-15, Daniel Veditz said, I'm pretty sure this will turn out to be a dupe of the bug on the installer not making sure Firefox is fully gone. Based on that, I'd like to remove the section altogether, if no one objects, since the underlying Firefox installer bug is fixed in Firefox and later. Alice 16:54, 1 July 2007 (UTC)

Section removed. Alice 16:58, 10 July 2007 (UTC)
