Web Compatibility Tweaks

[pythonr0ck]

The following tweaks are for better web compatibility, would it be a good idea to sort these into a separate "Web" section? I may make a PR later.

Polyfills by Poomsmart provides javascript polyfills to fix issues on rendering some websites.

Poomsmart also hosts specific website fixes for older versions of iOS: GithubWebLegacyCompat, ChatGPTWebLegacyCompat, SteamWebLegacyCompat.

For compatibility with all websites, Cyberkit by Ulnt2048 provides compatibility for all websites by backporting the WebKit engine to older versions packaged into the FireFox app (Fennec/Firefox release is the primary way of distributing Cyberkit).

Keeping this open as Cyberkit is yet to be added
