With all due respect, let me tell you what: ProxHTTPSProxyMII (available from @heinoganda by request via PM) provides full certificates (ciphers) and TLS 1.1/1.2 (although the latest updates have now solved the TLS issue) for both IE8 and other browsers (esp. Chrome 49). Thence, Chrome 49 / ProxHTTPSProxyMII fully solve the HTML5 issue. @roytam1's New Moon and Basilisk/UXP (best, IMO) also do solve the HTML5 and cipher issue, not requiring the addition of ProxHTTPSProxyMII. So I think we're pretty well covered on this matter. IMO there isn't any real HTML5 / cipher / TLS issue with XP at the moment. Moreover, @heinoganda also has been providing a certificate updater for the root cerificates and a flash updater specific for Chrome 49, allowing it to remain easy to use and functinal. Using IE8 just for MU/WU and either the latest Basilisk/UXP or Chrome 49 / ProxHTTPSProxyMII has provided me a fully satisfactory browsing experience up to now, and I bet it'll continue so for as long as @heinoganda and @roytam1 kindly keep on supporting the community with their awesome work.
