Search by contents of previously visited pages in Firefox

Question

Mozilla Firefox

There was a need to find a page that I previously visited and remember the contents of the page, i.e. actually keywords, but don't remember the title. So searching in Firefox history does not return any result. After doing some research, I found that some browsers have similar functionality, at least Safari (it works for Mac, I don’t know for Windows), Opera and Google Chrome. Description of the implementation of this function in Opera

Quote from the Opera help:

As you navigate, Opera creates a searchable history database that stores all the text content from all the pages you visit. To access this database, type a keyword in the address field, or use the Find field in the History panel. Some information is available from the opera:historysearch page.

Is it possible to implement similar functionality in Firefox? Among the additions did not find a suitable one. But maybe I searched badly?

Answer 1

Firefox does not save text content.
The best thing for history searching is Recall Monkey .

Answer 2

Maybe I'm strange, but the first thing that comes to mind is:
1) take the SQLite history base
2) programmatically go through all the addresses and get html
3) tear out the text with a parser (for example, htmlagilitypack)
4) find what you need
5) rejoice

Answer 3

Try searching the cache files directly or something like this add -on . But if the cache is disabled or very small, this will not help.
