Script Summary: Adds a simple button beneath your profile image to remove 'Recent Activities'
Note: Because of how facebook displays/renders data, sometimes a page will need to be reloaded for the button to appear or you can use the "User Script Command" from the GreaseMonkey icon (status bar)
Defaulted to using jQuery 1.3.2 because of a change in browser
sniffing code in jQuery 1.4 is not compatible with Greasemonkey (?)
without some modifications, see below on getting jQuery 1.4 to work:
Edits
jquery-1.4.1.min.js:
[old] 36: var o=r.createElement("div");n="on"+n;var m=n in o;
[new] 36: var o=r.createElement("div");n="on"+n;var m=true;
jquery-1.4.1.js
[old] 934: var isSupported = (eventName in el);
[old] 934: var isSupported = true;
Comment out commented code (1.3 <-> 1.4) and reload.
