I’m frustrated

Problem on FF 3.5 using feedly 1.2b

Feedly works after initial install/restart, but on the next restart, the feedly toolbar button disapears, and all feedly pages appear blank. The addons screen then shows that feedly is not compatible with ff3.5. Then I uninstalled it, reinstalled the latest version, and it worked again until I close and reopen ff again. I have done this process 4 times now.
