Pagea shift left in Foxfire

[MonicaX]

If I create a page using tables, one that's designed to expand vertically (the height of the page) as text or content is added, it shifts to the left slightly in Firefox when the table expands past a certain point -- it seems to vary.

This is really frustrating, because I want multiple pages to be appear stationary, when someone goes through the site and not shift from side to side. It's fine in IE and Safari.

Has anyone else seen this? And if so, what can I do about it?

Thanks

I figured it out. It's that the scroll bar appears in Firefox once the page is longer than screen height. And it appears to shift to the left. Duh. This bit of code forces the scroll bar to appear -- and problem solved:

html {
overflow-y: scroll;
}
