why does my resolution (or font size, or whatever) suddenly grow or shrink for a given web site while browsing?

I recently installed Firefox on a new Toshiba notebook, and have had one web site unexpectedly shrink, twice, and another one grow, as I'm browsing. When I leave and come back later, the particular site, but no others, is still affected. Am I inadvertently doing something to cause this?

OK, so I've just learned that I can reset the size change using control-0(zero). But the size up or down is enabled by control-+ or control--, and I'm not doing those -- it seems to be caused by something my fingers are doing on the cursor pad, since I'm not touching the keyboard as I'm browsing. Any thoughts as to what is causing this?
