Mozilla has announced that current AVIF image support is complete. Also, they claim previously encountered problems with the format have been resolved. We can expect Firefox 92 to have a full, compliant AVIF support enabled by default. Version 92 will be released on the 7th of September.
There have been other industry adoption for AVIF images, such as Microsoft with Windows. Google added support for AVIF to Chrome earlier this year and shipped it with Chrome 85.
Mozilla Firefox has encountered several errors and drawbacks that led to delayed support for AVIF, the image format based on the AV1 video codec.
There was a Mozilla bug ticket tracking the default support of AVIF. The patch enabling default support has initially been pushed but reverted as a result of broken tests. Those items have been reviewed. Then again, several open bugs and issues have led to support still not being the default. This has mainly to do with the current AVIF spec from AOM. In any case, Firefox will support AVIF images with its following versions. We can't wait for users to be able to use and view AVIF images directly.

In version 77 (released in June 2020), Mozilla recently implemented experimental support for the AVIF image format in Firefox. The feature is not enabled by default in the web browser's production version. Still, users interested in adding support may do so at the time of writing. When enabled, Firefox will render AVIF image files just like any other image format supported by the web browser. AVIF was developed from the AV1 video format and uses HEIF as the container and AV1 frames. It is a new format. AV1 is already supported in most web browsers, and the work has begun to integrate AVIF too.
If you want to find out your browser's version, open the Firefox settings located at the top right, head to the help menu, and click 'about'. If you have version 77 or above, you will be able to use the tutorial below to enable the AVIF image format.
Provided that you have installed a compatible version, you can easily add support for AVIF with the about:config configurations. Type about:config inside the address bar and press Enter.Most likely, a warning message will appear, telling you to be careful. No worries, we will be handling everything gently. Click on 'Accept the risk and continue'.In the search bar at the top of the page, search for avif. The option image.avif.enabled is the one you are looking for. If the second column's value shows 'false', click the right switch button to set it to true. A 'true' value means that Firefox supports AVIF, whereas a 'false' value means the browser's image format isn't supported.
Mozilla considers support to be experimental. However, most AVIF files should be rendered successfully, and full native support is expected to arrive in the early months of 2021. Remember to restart Firefox. Then come back to this page to see this fantastic image:
