This news is not OLS related, but many OLS users use the cache plugin for WordPress.
The issue is that Firefox changes HTTP Accept Header values. Before version 129 the accept header was:
Since version 129 the accept header is:
LiteSpeed cache plugin for WordPress checks the accept header to define a cache vary rewrite rule in .htaccess if image/webp value exists in accept header string. If this value doesn't exist the user gets standard image displayed. This was/is especially true for iphone users if they have Safari browser version < 13 installed, but the change to the Firefox browser makes Firefox work like an outdated Safari browser on iphone. Means Firefox loads jpg|png images instead of webp images since there is no replacement although FF supports webp images.
Solution 1:
Wait for cache plugin update that has to be updated since 4 months to fix it.
Solution 2:
Use the AWR plugin. The AWR plugin not only provides a fix for this issue, but makes the LiteSpeed cache plugin also avif ready and images can be converted on own server instead of quic.cloud. Check it out: https://www.cachecrawler.com/WP-Plu...e-Conversion-for-LiteSpeed-LScache::6574.html
