Running two days now, no problems to report, FWIW.

Running for a few days now, two machines have both had browser "lock-ups". In Task Manager both showed no program running in Applications however both were showing Processes running.
One did manage to End Process, the other had to be rebooted. This is not a new phenomenon to me.
All other programs remained working ok when Firefox had seized.

Hmm . . . developing a new site, and am having intermittent issues with random images not displaying. Cross testing in IE simultaneously, and not having issues there.
When requested from the server, an image just "goes missing." No broken icon, just the alt displays. Refresh, it comes in, a different image goes missing. CTRL-F5 and same random result, sometimes it takes 5 or 6 hits to verify all pages are rendering properly.
It's sometimes CSS url images, sometimes direct in-page src=.
Meanwhile IE is fine. I hate to admit it.

I also have images not displaying occasionally, but it appears to be adblock. Seems its more sensitive since the upgrade to 3.6.3.

No adblock here, FWIW, just development add ons. But . . . . could be something else.
