That is most likely caused by Firefox releasing memory used in that tab to minimize the memory that is currently in use.
This includes memory that stores the DOM tree and that tree needs to be rebuild to allow navigation scrolling and clicking items on the page.
On complicated pages that have a lot of elements this can take a few seconds.
