Firefox fails to render .heic images
Dear colleagues:
I have made a page with a stack of z-indexed .heic images. The viewer clicks (jQuery) on the top image to reveal the next.
The page is local, not online. I'm on a Mac mini 2018, OS Ventura 13.6.1, Firefox 13.0.
Safari renders the operation correctly. Firefox fails to load the .heic images. Chrome also fails to load the images.
Any suggestions welcome. My 83yo brain sometimes misses things. cheers Chris

From what location are you loading those images ? Is that in your OS user directory as you may not have access to this location due to sandbox restrictions?
You can check the Web Console (Tools -> Web Developer) for messages about blocked content and about the presence of mixed or unsafe content.
You can check the Network Monitor to see if content is blocked or otherwise fails to load.
If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.
I'm not sure if desktop Firefox does support this image format due to licensing issues.
Thanks for Command+Shift+R I've been clearing history and cache and opening new private window each time.
Neither Chrome nor Firefox render heics: http://wavehands.net/dancesHEIC/dancesHeic.htm
but each is happy with jpegs and pngs: https://wavehands.net/dancesJPG/dancesJPG.htm
Safari renders both ok.
cheers
Surah, I gave thumbs down because you had not looked at the tests online.
Safari with user agent Google Chrome Windows and user agent Microsoft Edge renders the heic version correctly. The problem may be limited to mac OS heics.
Cheers.
Heic is proprietary format from Apple as such they don't just give it out unless some pays licenses fee subscription from Apple to use it. So blame Apple for doing this not Firefox or Chrome, why should they support a obscure format when jpg, png, gif are widely used format and works just fine.
A simple search of heic reveals this. And no one else uses it.
"It's the default image format for Apple devices that run iOS 11 or later"
