Been having trouble with flash player in Firefox, in my dark\nbackground Windows color scheme. I do Windows backups, so my\nsystem is neat. But for some strange reason, flash player has been\nmessing up in YouTube, for weeks or longer, through several\ninstallations and restorations (of various things).\n\nMy latest attempt to solve the problem... Found a link to the\ninstant installation page on Adobe's website, and made a shortcut\nto it. I grabbed the latest flash player uninstaller. Left open\nonly one tab in Firefox, a text page, and closed Firefox. Ran the\nuninstaller. Opened Firefox and browsed to that Adobe flash player\ninstallation page, to install it. Might have closed Firefox.\nBrowsed to YouTube, and BOOM everything is correct for a change.\n\nI think that about sums up everything I did. Something that looked\ntroublesome (before) is the way Firefox handled the flash player\nupdate. I was getting two prompts (the information bar and\nanother) to install flash player, and then somehow the video was\nplayed anyway, supposedly before flash player was installed. But\nthe video windows looked very wrong, then and after I accepted the\nmanual install.
