Background

This preference allows disabling of extension compatibility checking. This is useful if you are using alpha, beta or nightly (development) builds which Add-on authors do not yet support.

Possible values and their effects

true

Check extension compatibility on install and update. (Default)

false

Do not check compatibility. Incompatible add-ons will be marked in the Add-ons Manager - its icon will have an exclamation mark over it and when the add-on is selected, the text "This extension is not compatible with Firefox 2.0" appears below the extension description. In addition, while the preference is set to false there will be an alert bar at the top of the Add-ons Manager saying that compatibility checking is disabled and that you may have incompatible add-ons, with a button to re-enable it.

Caveats

  • This preference does not exist by default.
  • Installing an extension marked as incompatible with your application may cause your application to malfunction or crash.
  • Disabling extension compatibility checking may cause your application to malfunction or crash after a future upgrade.

If disabling extension compatibility checking makes your application crash on startup, you should try starting in Safe Mode and re-enabling compatibility checking.

UI

Mozilla Firefox 2.0

This preference can be toggled to true by clicking the button in the Add-ons Manager next to the “compatibility checking disabled” alert. (There is no way to set it back to false within the UI.) In other words if you click on "Enable" you are not enabling extensions but enabling the compatibility checking and the flagged extensions will be disabled once more and not function. To Enable the disabled extensions you will have to start over by creating the configuration variable all over again.
