1780420 - Installing Firefox in a folder named '中國的 ~=[]()%+{}@;’#!$' is allowed, but the build will crash at every launch

Status: RESOLVED WORKSFORME

(Toolkit :: Startup and Profile System, defect)

Description

[Daniel Bodea [:danibodea]]

Note

• If the user creates a folder with the name '中國的 ~=%+{}@;’#!$', launches the installer and chooses the folder as an install location, the build will install, but when launching is attempted, it will crash instantly.

** Found in**

• ESR v102.1.0esr

Affected versions

• Nightly v104.0a1
• ESR v102.1.0esr
• 101 rc

Affected platforms

• Windows 10
• Windows 7
• It appears to also occur on Ubuntu 22, by renaming the folder to the corrupted string, but unlike Windows, the Profile Manager is not opened either
• It does NOT occur on Mac OS, by modifying the Application name to the corrupted string.

Steps to reproduce

1. Create a folder with name '中國的 ~=%+{}@;’#!$' on the Desktop
2. Launch the installer and select custom settings, then choose the folder above as install location
3. Complete installation.
4. Launch build.

Expected result

• Build launches correctly.

Actual result

• Build crashes at launch.

Regression range

• Not a regression as it also occurs on a Nightly v45.0a1.

Additional notes

• Crash:

• Also occurs by downloading a zip archive and renaming the build folder to the corrupted string (Windows).

Ultimately, the crash is an issue with Firefox itself, so I'm moving this bug elsewhere. In theory we could try to prevent installs to locations such as this, but we wouldn't be able to make any guarantees (some people run builds of a .zip, they could rename directories later, etc., etc.). Let's file a separate bug for that if it becomes necessary.

Since the crash volume is low (less than 5 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.

Closing because no crashes reported for 12 weeks.
