GM_openInTabs (0.9.5) does not work at all for me with FF 3.6.17. Reverting to 0.9.3 makes things work.
In the Error Console I see the message: Error: browser.tabs is undefined Source File: file:///C:/Users ... /components/greasemonkey.js Line: 287 This happens in a freshly created profile with only Greasemonkey added. -- You received this message because you are subscribed to the Google Groups "greasemonkey-users" group.
