275827 - Javascript Console not enabled by default

Status: RESOLVED WONTFIX

(Toolkit Graveyard :: Error Console, defect)

Description

[Peter Wilson]

The about:config option Javascript.options.ShowInConsole was turned off by
default when I installed Firefox. When displaying the Javascript Console my
expectation of seeing any JS parsing errors lead me to spend many hours persuing
other possible causes. It should be turned on by default.
I previously had Mozilla 1.7 installed - is this an artefact of the previous
installation?

Looks to me like showinconsole controls whether or not errors in chrome
JavaScript are shown, not whether or not errors in content JavaScript are shown.
With it false, data:text/html,<script>foo=</script> still shows up as an error
in the console.

Is it your contention that people who will be helped by seeing ""Access to
XPConnect service denied. [nsILDAPMessageListener::onLDAPMessage]" nsresult:
"0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)"" but can't find the pref in
about:config are more numerous than those who will be baffled and alarmed (and
will file duplicate bugs) when Page Info messes up its tree and throws a string
of thirty errors?

comment #1 is absolutely correct. The variable in question helps debug chrome
javascript and should not be turned on by default
