1406774 - Debugger broken outside safe mode

Status: RESOLVED FIXED

(DevTools :: Debugger, defect)

Description

[inkatadoc]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:56.0) Gecko/20100101 Firefox/56.0
Build ID: 20171003101344

Steps to reproduce:

Try to use the Javascript debugger.

F12 -> choose debugger tab


Actual results:

Debug tab open, but nothing works. Javascript files do not load, cannot set breakpoints. The main panel is blank.

HOWEVER

If I start in safe mode, the debugger works fine.

I tried multiple combinations of safe mode and/or refresh profile and the only consistent way to get a working debugger is in safe mode.




Expected results:

Launching FF in the console, I get the following error

console.error: 
  Message: TypeError: str is null

IF I launch FF with the --safe-mode flag, no errors are produced and the debugger works fine.

Hello inkatadoc!  Were you on Spanish (MX) language?  If so I believe we've found the fix today.  Please let me know!

I'm not positive, but it's highly probable. I mean I'm sure my interface is in spanish, but not sure if it was the MX variant.
