The latest "stable" versions is 188.8.131.52. Is that what you have?
Does it fail with any other browsers, Chrome for example?
You might try going into your System Preferences, Flash Player, selecting the Advanced tab, and delete all browser data and settings.
There's also a Storage tape in the preference pane that includes an option to delete all local storage settings by site. You might also consider that or doing it selectively (by site).
I cannot recall ever being this frustrated with my Mac and I have been faithfully using Mac for 20+ years!!
I am currently using a Macbook Pro 2.3 Ghz intel Core i7 4GB RAM Mac OSX 10.7.5
Very slow browsers chrome, safari, firefox - have tried them all in hopes of finding one that works with no luck!!
Adobe Flash crash error codes all the time. I receive update request links from all three browsers asking me to update adobe flash software which I have done repeatedly numerous times with absolutely no success, just a waste of time and lots of frustration.
Spinning rainbow sprocket is a common thing on my macbook, drives me insane!!
I found this thread and followed the instructions to go into "System Preferences, Flash Player, selecting the Advanced tab, and delete all browser data and settings." I then updated my Adobe Flash in my System Preferences, not the typical browser update method.
So far, this method appears to be working - will keep my fingers crossed!!!
