Reproducible: Always Steps to Reproduce: 1. just create a table of width="99999999" and height="99999999" 2. set a small table background image 3. display the page in firefox Actual Results: the table background image that should be displayed tiled over the whole table is just shown once on the top left corner. note that there are no scroll-bars neither horizontal nor vertical. Expected Results: it should have shown the whole table and let me scroll all over it like in internet explorer. please let me say why the hell I need to display such a big page: I'm working on a project doing the largest webpage in the world. and therefore I would like it to work in firefox as well! private people, institutions and small companies should be allowed to buy sections on the page and be respresentet that way. so I offer you a large piece of land on this page if you manage to display my width="999999999999999999999999999" table!

Usual units issue.... roc, do we have something reasonable to dup this to?

This one's a bit unusual. I don't know of any bugs that ask us to support very large values like this.

reporter could you please attach a testcase to the bug?

the previous attachment does not belong to this bug

its the last 9 that makes this happening

the behavior changes at 17895697 px which on my machine corresponds to 0x3FFFFFFC (60 twips) above this we do not clamp to 0x40000000 like we do for width but use the reminder over nscoord_MAX (which is 0x40000000)
