Status: RESOLVED WORKSFORME

(Toolkit :: Add-ons Manager, defect)

Description

[Simon Bünzli]

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a8pre) Gecko/2007082105 Minefield/3.0a8pre

Steps to Reproduce:
1. Open the Plug-ins view of the Add-ons Manager
2. In case you don't have two plug-ins starting with the same letter, get one (e.g. "RealPlayer" and "RealPlayer G2 LiveConnect" or a "Microsoft..." one in addition to "Mozilla Default Plug-in")
3. Press the key for that initial letter and keep it pressed for a few seconds (thus triggering FAYT)

Actual result:
After every two or three passed keypresses, FAYT stops briefly and the following error is thrown:

Error: document.getAnonymousNodes(this._opType) has no properties
Source File: chrome://mozapps/content/extensions/extensions.xml

note: I was able to reproduce this in the extensions view so this isn't specific to plugins.

Just tried to reproduce several times in the plugins, extensions, and themes views and was unable to. Simon, could you check if the error is still thrown with the latest nightly?

Indeed, can't reproduce it, either. FAYT still notably lags, but this errors seems gone.
