Hello,
When you click on the 'right' or 'left' arrow to change by a month the whole calendar shifts to the right making it only partly visible. Probably linked I've noticed that when you start up the calendar the calendar sort of jumps from the right to the centre.
the problem is that the status=no is not disappearing for some reason in Firefox and when it decides to show the progress meter (i.e. changing data) it thinks the size is wider and adjusts the calendar output accordingly.
This is further exaggerated if you use any plug-ins that use the status bar, e.g. weather forecast. I tried it with a weather forecast plug-in and it makes the calendar go out of view by about 300 pixels!
Hope this helps.
