Greasemonkey 0.5.1 has officially been marked safe for public consumption. I suppose this is a good a time as any to point out that all of my scripts will work with the new Greasemonkey under Firefox 1.0.x. If yours stop working when you upgrade, get the latest version, as adjustments had to be made to some scripts. As far as Deer Park (which will be Firefox 1.5 or thereabouts, once it’s deemed complete), mostly they will not work. If experience is any teacher, the scripts will probably not be fixed for Deer Park until it becomes a day-to-day issue for me. If there’s a script you can’t live without in the meantime and you’re running Deer Park, don’t be afraid to let me know.
