Firefox Focus Safari extension causes icons and symbols to render as empty squares in Safari on iOS 26.5.

Hello Mozilla Community, After updating my iPhone to iOS 26.5, I experienced an issue where certain icons and symbols in Safari were displayed as empty squares (□) or the symbol name (e.g. Chevron Right) instead of rendering correctly. After some troubleshooting, I found that the issue appeared to be related to the Firefox Focus Safari extension. When I disabled and removed the Firefox Focus extension and then restarted Safari, the symbols displayed correctly again. This suggests there may be a compatibility issue between the Firefox Focus Safari extension and iOS 26.5, potentially affecting font or icon rendering on websites. Could you please let me know if this is a known issue and whether there is a fix or workaround available? Device: iPhone 12 Mini iOS version: 26.5 Firefox Focus version: 151.3.1 (72936) Thank you for your help.
