Good idea. There's a few minor niggles, though: 1. Don't use `unsafeWindow`, this will break in Chrome and will not even work in Firefox+Greasemonkey if the effective `@grant` changes. 1. Avoid leading `*` wildcards in `@includes`, if you can help it. This is a big performance hit. `@match` limits the wildcard scope and performs much better and reports the sites/security correctly on Chrome. This gets all current SE sites: // @match *://*.askubuntu.com/questions/* // @match *://*.onstartups.com/questions/* // @match *://*.serverfault.com/questions/* // @match *://*.stackapps.com/questions/* // @match *://*.stackexchange.com/questions/* // @match *://*.stackoverflow.com/questions/* // @match *://*.superuser.com/questions/* 1. The regex `match` needs to be more robust, to account for all legal characters in the URL, and for anchors. 1. Use injection so that the script will work on most userscript-capable browsers (Chrome, Firefox, Opera, Safari, etc.). <br> Here's a variant of the script I've been using. It also adds a "revisions" link since a post's history is sometimes hidden. It works on Chrome and Firefox, and should work on most other userscript-capable browsers: View [the source at GitHub Gist][1].
