Rated 4 out of 5 stars

FINALLY I found the cause for FF_9 crashes, puh. I even went through the ORDEAL of creating a new profile, exporting / importing most settings, the whole spiel, and now - by happenstance, stumbled across the root cause: turning on thumbnail caching caused the crashes, and Mariner's & rguer45's comments confirmed my suspicion that I'm not alone out there.

One of my essential addons. Has been rock-solid for years. 4-stars due to crisis described above. I'm even over the fact that so far Panorama and Showcase complement each other (rather than one doing the whole job). Thanks and much awaiting a FIIIIIIIIIIIIIIIIIIIIIIX. (but again: HUGE sigh of relief to have found the cause-of-crash)

had I only known earlier..............;-/

This review is for a previous version of the add-on (0.9.5.8).
