Firefox 35 not rendering some progressive jpg files

Question

Followed with interest discussion about a similar problem being experienced by EGCDAN ( https://support.mozilla.org/en-US/questions/1044546).
Before trying to follow the possible solutions offered, I checked the same page with IE 11 and all the images rendered perfectly as they did at one time with Firefox.
You can check this by loading my page http://www.consider-the-lilies.org/Jack-go-to-bed-at-noon.html and hover over the line: "(Other wildflowers in the Gallery with short-lived blossoms include Chicory, Blue-eyed Grass, Scarlet Pimpernel, Virginia Spiderwort, and Asiatic Dayflower.) "
No problem with IE, at least for me; still partial rendering for Firefox for some of the images.
???
