Over the last few days my "Find in Page" function has stopped working. If I type Ctrl-F the window opens in the status bar. I can type one letter that highlights some - but not all - instances of that letter on the page. As soon as I type a second letter the field goes pink. Is it possible this is something easy to fix without having to completely reload Firefox? Yes, it's a very old version of Firefox. But it's worked perfectly until now.
