Hello, I found out just now that the navbar-toggler-icon was not visible in Firefox in Mobile viewport. I found the solution reading http://stackoverflow.com/questions/30733607/svg-data-image-not-working-on-firefox So line 6177 in mdb.css .navbar.navbar-dark .navbar-toggler-icon { background-image: url("data:image/svg+xml;charset=utf8,%3Csvg viewBox='0 0 32 32' xmlns='http://www.w3.org/2000/svg'%3E%3Cpath stroke='#fff' stroke-width='2' stroke-linecap='round' stroke-miterlimit='10' d='M4 8h24M4 16h24M4 24h24'/%3E%3C/svg%3E"); } should be corrected to .navbar.navbar-dark .navbar-toggler-icon { background-image: url("data:image/svg+xml;charset=utf8,%3Csvg viewBox='0 0 32 32' xmlns='http://www.w3.org/2000/svg'%3E%3Cpath stroke='%23fff' stroke-width='2' stroke-linecap='round' stroke-miterlimit='10' d='M4 8h24M4 16h24M4 24h24'/%3E%3C/svg%3E"); } So replacing #fff by %23fff This does the trick. Can this be corrected please in the new version, so I have a minified version of the correction? Or do you have a good minify tool or URL I can use to generate it myself? Best regards
