If you are a Firefox user, be aware that as of yesterday Mozilla has released version 184.108.40.206 of the browser, coming a very short time after the last update to 220.127.116.11. It's a fairly minor update, affecting how the browser handles some media content as well as offering improved stability. If you've been having trouble playing streaming video, it's probably a worthwhile update. Aside from that, it may have updated itself already should you allow it to do such. It's also a good idea to keep up to date, to make it less of a hassle when newer versions come out.
