This page completed a technical review from Martijn Wargers (:mwargers) (Mozilla QA Team) on 2014-10-30. This article has been created from this page from QMO: Firefox Mobile: Enabling the Error Console
This tutorial assumes that you have
- Firefox Mobile or Fennec installed on your mobile Android device
You can set user preferences via the advanced preferences editor, by typing
about:config in the Location Bar. The Error Console can be enabled by searching for and toggling the preference, false to true, named:
devtools.errorconsole.enabled. [caption id="attachment_25762" align="alignnone" width="210"] about:config[/caption] Note: Changing any other advanced options can be harmful to the stability, security and performance of Firefox Mobile. Use with caution.
Step 2. Accessing the Error Console
After toggling the preference from false to true, one can access the Error Console inside Firefox Mobile’s preference panes [caption id="attachment_25763" align="alignnone" width="210"] Preferences[/caption] One can access the preferences by panning to the right side of the browser and tapping the cog-wheel on the right sidebar. [caption id="attachment_25764" align="alignnone" width="150"] Error Console[/caption] From inside the preferences window, select the last available pane on the far right. This is the Error Console, and is indicated with a spider icon.
Step 3: Using the Error Console
From the Error Console one can see various types of errors that are accessible across various tabs: Error
- Very similar to warnings, used very rarely
There is always information about the type of error or warning and the location of the file that was involved, and the information indicated can be useful for posting into filed bugs, whether it's a site issue or problem with the browser. Tip: Each entry can be copied to clipboard with a long hold tap on any warning, message or error and selecting 'Copy'.
