Confirming. For me the alert appears, but after pressing OK Firefox opens as normal. In Safe Mode there is no alert.

My installed extensions:

DOM Inspector 1.8.0.7
Chatzilla 0.9.75
Hebrew Calendar 1.0.4.35
Talkback 1.5.0.7

Does the same error appears when starting Firefox in Safe Mode? Is anything written to the Error Console (strict js enabled)?
Does anybody who sees this *not* have the Hebrew Calendar extension? It has also been reported in comments on https://addons.mozilla.org/firefox/1379/ and on http://hcalendar.blogspot.com/ and various fora.
The Extension "Hebrew Calendar" causes the problem. I assume it is not [yet] compatible with the 1.5.0.7 revisions.
Because that it is a bug for an addon this bug is INVALID.

Before anyone (like me) gets tempted to reopen this because it might have been an unintended API change in 1.5.0.7, comments on the addons page and the extension's weblog say that the error is also triggered in Firefox versions before 1.5.0.7, and thus it was just coincidence that the extension released an update at the same time as 1.5.0.7's release, so people were seeing both updates in the same Firefox restart.

Version 1.0.4.36 of the Hebrew Calendar extension has a fix for this problem. Goto Tools > Extensions and hit the Find Updates button, then the Update Now button. Restart Firefox.

I am constantly getting this error
  "ALERT
  "ReferenceError:  JEvent is not defined"
in current versions of both Firefox and Thunderbird.
It is VERY annoying!
After reading all of the info on this bug and elsewhere, it seemed to me that this problem was related to the Hebrew Calender extension.  

When I updated both FF and TB to the new version v1.0.4.38, closed both programs, and then restarted them -- voila! the JEVENT problem had disappeared.
Since I updated the Hebrew Calendar, I have not had a problem either.
