When an update was downloaded, it gets installed after Firefox is restarted. The progress window shows up and when it's gone, I get an error message telling that the upgrade failed and I should close all applications to retry. But even when I close all applications, the problem won't go away. The only chance to stop this message from re-appearing over and over again is to kill the firefox.exe process.

Today that failed because it was already gone. Instead I then immediately killed the update.exe process. Upon next start of Firefox I got the message that incremental update failed and the full version is not being downloaded. I don't want that so I quit Firefox and restarted it. Now no upgrade is done at all and I could go to and get that installer myself, for my local archive.

Reproducible: Always

This has happened for at least the last 2 or 3 upgrades of 2.0.0.x. It worked fine before. All on Windows XP SP2.

Okay, wait, the full setup also failed but this time, it gave me an concrete error message that I could work with. It said that the file nssckbi.dll in Firefox' programme directory was locked. A search with an old tool said that Thunderbird was locking that file. So probably the error message of auto-update was correct, but also quite useless.

Maybe I should investigate Thunderbird and report a bug because it grabs Firefox files that it's not supposed to touch!

the version notes indicate that auto-update, "Software Update will not work if Firefox is installed to a location on your disk to which you do not have write access, since Software Update needs to replace or create files in this location."

So, you need to make such directory not "read-only", not lecture-seule.

I'm resolving this bug as a DUPLICATE of bug 340535.

If you want to install Firefox, then download it at
then manually uninstall via Control Panel/Remove or add programs
then install
