Using Firefox with Apple Mac running OS X v 10.7.1 and Parallels 6, and Windows Vista as a virtual computer. Have Firefox 6.o installed on the Mac and Firefox 6.0 for Windows installed within Microsoft Vista running under Parallels 6 as a virtual machine. Issue 1) Within Mozilla on the Mac whenever I power down and restart the computer all my app tabs and web page tabs are lost except for my home page, even though I have set up Firefox preference to remember my open web pages/tabs. Issue 2) Within Firefox running within Vista on the virtual machine my web pages are remembered but I cannot figure out how to create a app tab.
