It is title="xyz" that should appear on over, not alt="xxy", the alt is what is supposed to show if the images cannot be found or shown. IE9 will display the title if it is supplied.

If you have a lot of pages that were written for IE only you could install an extension.

If you right-click on the image and choose properties you can see both title and alt text, but since that was removed in 3.6 , you will have to install

Thanks so much for the immediate reply! I did install this extension, and it shows to be installed on Firefox as "Element Properties 6". However, this did not enable the title text to display. I am very basic in html, and the website I am dealing with was constructed in Front Page and tweaked on the code side. If someone has a fully functional Firefox installation, it would be interesting if they looked at this site to see if title text appears for them: http://www.pianotuningphoenix.com/ -- all images and many text blocks have title text installed. I like Firefox and would like to know more about it and make it work well. And thanks to dmcritchie for the initial detailed rapid response!

Again, to dmcritchie: I looked at my code, and found to my surprise (it's been 3 years since I built this site "www.pianotuningphoenix.com") that I didn't have the html code word entry "title" on most of the images -- referring to Home/Index Page. Where it does exist, hovering the cursor over an image does produce the title text in Firefox (now that Element Properties 6 is installed). The answer is now clear, that I will have to install the html title entry in order to get Firefox to read it -- for reasons unknown IE9 reads the text designated as "alt" via hovering cursor over image the same as if it were title text.
