My Firefox upgraded itself automatically to version 3.6, and I found that IE tab is broken there. Apparently IE tab is known to be broken in this version.
Are there any known workarounds such as these?
a different plugin with the same functionality
a way to tell FF to behave in some legacy or compatibility mode for certain plugins
a new version of IE tab
In the meanwhile I'm glad that Chrome's current release supports plugins, and IE tab works there.
