We're developing a responsive site for a shopping centre, and I'm in the middle of building a store directory HTML page. However, it has caused some strangeness in Firefox. Linky.

Looks fine in Chrome, but in Firefox, as soon as you try to filter the results the table leaps about the page when it refreshes the data. I am presently perplexed as to why, and would welcome theories. This doesn't apply when the table is absolutely positioned, but that solution comes with its own box of problems.

This page isn't currently responsive. Although the Homepage and Store Pages are.

Many thanks
