I'm not sure if this is a layout or DOM issue (or something else), but I'm guessing layout.
In: http://www.macridesweb.com/oltest/MODAL.html I use this javascript: var OLmRoot=(document.compatMode&&document.compatMode=='BackCompat')?'body':'html'; var root=document.getElementsByTagName(OLmRoot)[0]; if (root.style.overflow!='hidden') root.style.overflow='hidden'; to temporarily suppress any scrolling of the document by eliminating its scroll bars (and later, after a user action, I restore the scroll bars). To see the problem, scroll the document vertically until the 'Modal dialog' link is at the top of the viewport, and then activate that link. In IE and Opera there is a very modest horizontal shift of the document due to reflow associated with the removal of the vertical scroll bar (because the document content is using a horizontal centering style). But in Firefox the document is reset (shifted both horizontally and vertically) to its 0,0 position before being centered horizontally. I save the upper-left screen coordinates, and use self.scrollTo() to restore the document's position when the scroll bars are restored, so this was not a big issue in my mind, but a number of users have complained that, in so many words, the substantial jump of the document display in Firefox is jarring and causes them emotional distress. :<) In any case, it does seem like a bug in Firefox when compared to IE and Opera, so I'm raising the issue here for feedback from the Firefox developers. I'm using the recently released Firefox v2.0 (rv: 1.8.1), but was using v1.5.0.8 (rv: 1.8.0.8) which also has this problem.
