Here’s a list of options I modified in my firefox’s about:config.

  • middlemouse.contentLoadURL: false

    I use the mouse middle click to copy and paste stuff. So when I accidentally press that mouse middle click while reading a web page, I don’t want Firefox to load whatever’s in my buffer as a URL.

  • browser.urlbar.trimURLs: false

    Mozilla decided to look more like Google Chrome and started to hide relevant parts of the URL like http://. This feature has helped me exactly 0 time, while on the other hand it was annoying many times when copy/pasting from the URL bar would not give me the entire URL (and the results were not consistent).

  • Disabling unsecure ciphers

    • security.ssl3.ecdh_ecdsa_rc4_128_sha
    • security.ssl3.ecdh_rsa_rc4_128_sha
    • security.ssl3.ecdhe_ecdsa_rc4_128_sha
    • security.ssl3.ecdhe_rsa_rc4_128_sha
    • security.ssl3.rsa_rc4_128_md5 [this one seems required for Youtube's https to work]
    • security.ssl3.rsa_rc4_128_sha

    You can now check if your browser uses secure SSL/TLS cipher.

  • Replace Google with DuckDuckGo on Firefox

    • browser.search.defaultenginename: DuckDuckGo
    • browser.search.selectedEngine: DuckDuckGo
