Hi Mozilla Community, I’ve noticed that several websites don’t function properly on Firefox, especially when it comes to form submissions, dropdown menus, or login buttons not responding. For example, while testing my own pet blog [https://pawbreed.com https://pawbreed.com], which provides dog breed guides and care tips, some users reported layout issues and broken navigation only on Firefox Chrome and Edge load it perfectly. I’ve also experienced similar problems on sites like Blick Art Supplies and state tax portals. Could this be related to specific browser settings, add-ons, or compatibility modes? I’ve tried clearing cache and disabling extensions but the issues persist. Is there a best practice for ensuring cross-browser compatibility, particularly with Firefox? Any advice would be greatly appreciated. Thanks!
