This has happened more than once. I am reading articles on a couple of tabs. All of a sudden one of the webpages that I am looking at drastically shrinks in size so it is difficult to read. The page had been a normal size (not large), but it automatically shrinks and I haven't been able to figure out how to get it back to its original size. It's very irritating. I've heard of some people wanting to increase the page size, but I can't imagine why someone would want to shrink what they are trying to read.
