An ordinary re-install of Firefox will not result in loss of toolbars or bookmarks, however it will not necessarily help with the crashing problem.

Sometimes you may get automated responses after certain crashes, but more usually you have to take further action yourself to sort out the problem.

Firefox will try to restore tabs the first time it crashes, but if it quickly crashes again then the second time it will instead give you the restore screen of options, at the ottom of that is an option to restart a fresh session of firefox, instead of trying to restore the tabs, or you may selectively choose which tabs to restore. See
