Do you use the Firefox inline search (not the search web box, but the search to find text in webpages) to frequently search for text in a webpage? If you do, there may be instances where you want to search for the same text in multiple pages.
A simple trick to search smartly in Firefox allows you to search the same text without the need to type it in the inline search box again, however a much better solution is available in the form of a Firefox add-on, that will allow you to keep a history of your inline searches.
The FindList Firefox add-on turns the find box in a drop down list, remembering the last 15 items you had searched using the inline search.
FindList is a experimental add-on, you will have to login to Mozilla Add-ons before you can download and use it.
