"No Adblock Plus icon" issue in Firefox fixed for some scenarios · 2013-10-01 12:36 by Wladimir Palant
Adblock Plus 188.8.131.5221 for Firefox should resolve a long-standing issue where some people didn’t have any Adblock Plus user interface (especially no icon) in the Firefox windows opened on startup. We could trace that issue back to delays in the Firefox startup sequence, e.g. caused by a master password prompt showing up before any Firefox windows. The result was Adblock Plus not “noticing” these Firefox windows when it initialized.
Technical details: This issue was introduced in February by our fix for bug 819561 (Pages opened by Adblock Plus during installation should open in the same PB window). There we switched to a different approach to enumerate Firefox windows. However, this enumeration approach turned out to ignore windows that were already open but didn’t become visible yet. Now we are combining both enumeration approaches to make sure that no windows are missed.
