Description (last modified by trev)


FF 36 (Windows XP)

How to reproduce

  • Open Filter Preferences window.
  • Press Ctrl+F to search for a filter, type "asdf123456789".

Expected result: the filter isn't found, so the input field should turn red and there should be a corresponding message.

Actual result: no visual feedback if filter isn't found. Also errors in Error Console:

NS_ERROR_FAILURE: Failure arg 0 [nsIEventListenerService.addSystemEventListener] findbar.xml:266:0

NS_ERROR_FAILURE: Failure arg 0 [nsIEventListenerService.removeSystemEventListener] findbar.xml:255:0


The exception comes from the browser's findbar widget. It calls nsIEventListenerService.addSystemEventListener() with this._browser as first parameter. In our case its value isn't a DOM element however but a fake browser object, hence the exception. Originally it was calling this._browser.addEventListener() which we emulate. The only impact appears to be missing feedback if the search failed.

What to change

Instead of using a separate object, inject the properties of the fake browser into the filtersTree element. As this one is a real DOM element, nsIEventListenerService.addSystemEventListener() will work on it.
