commit 6344196616349a814c4ce040ea01236536f44f7e Author: Mike Perry mikeperry-git@fscked.org Date: Thu Aug 25 13:27:53 2011 -0700
Bug #3580: Fix hotmail (but only for TBB users)
Hotmail appears to have an optimization strategy that involved pre-loading all of the scripts involved in their site as object tags. When the user navigates between pages, the appropriate object tags get converted into script tags and executed.
The problem for us is that docSell.allowPlugins is implemented as a content policy that blocks object tags for a given page. We use this API because the toggle model requires the ability to do per-page plugin control.
Firefox 3.6 introduced a global plugin control API that allows us to enable/disable indivual plugins, but this was unfit for use in the toggle situation where tabs might sit around in the background.
However, we can use it for TBB. This patch switches us to using the plugin manager API, in TBB only. --- src/chrome/content/torbutton.js | 41 ++++++++++++++++++++++++++++++++------ 1 files changed, 34 insertions(+), 7 deletions(-)
