Safari to Firefox

Well after a long hold out I am finally switching to Firefox. My biggest complaint about Firefox has been the UI particularly in the form widgets. There are a couple of things you can do to take the ugliness away, such as using Firefoxy or downloading a G4, G5, or MacBook optimized version. Those help but it still breaks in certain places because it is not a native Cocoa app. Well I have decided I am willing to live with that until the supposed native Cocoa version 3 comes out. My other current pet peeve is that Firefox does not use Apple’s Spelling Service. Most of my other issues I was able to fix with either a plugin, or a Greasemonkey userscript. The main reason I switched is that at work Safari started to randomly crash and got really annoying. Well I started using Firefox at work to minimize the crashes and noticed that Safari was not rendering all the content on certain sites, in particular, the interface to my WordPress blogging software. So I switched. Well now I am looking for three plugins, and am hoping someone out there will be able to point me in the right direction, or be really cool and step up and write the plugin (wink, wink, nudge, nudge). The first is a simple drop down arrow in the search pane that allows you to see your search history. The second is a plugin like DownloadComment for Safari, this plugin adds the url of the site to the Spotlight comments of a downloaded file. And lastly I would really like for Inquisitor to be ported to Firefox.
