Craigslist search plugin for Firefox
So, I noticed a while ago that the firefox search plugin for craigslist's for sale section was broken. I waited and waited for it to get updated, but then I took a closer look at their contribution guidelines and it says that submissions for new plugins is currently down, meaning that chances of the plugin getting updated anytime soon are pretty slim. So I took matters into my own hands and fixed the damn thing myself.
Now, this is a "partial" plugin, meaning that it only works for part of the search form features. Right now it will only work for the SF Bay Area, and only for the general For Sale section. If you want to make it specific for your local, take a look at the .src file in a text editor, and you can see that it is well commented (by the previous author), and you can easily find the form value to change.
To use this, just download the src file and this gif, and put them in Firefox's "search plugins" folder. For Windows, it will probably be in C:\Program Files\Mozilla Firefox\search plugins\. For OS X, you will have to right click (or command click) on the Firefox app icon itself and choose "show package contents". This will open the app folder. From there, navigate to "Contents\MacOS\searchplugins\".
Once you drop in the two files, restart Firefox if it was running, and you should see it in the search bar dropdown list. (BTW, anyone know how to implement an installer for search plugins?)
