Bing Chat and Copilot for Firefox troch Choc1024

Enables Bing Chat and Microsoft Copilot for firefox. It enables you to use bing.com/chat and copilot.microsoft.com without the 5 messages / conversation limit! (You will still have the 30 messages limit though, I can't change that.) Please not that this is a fork of https://github.com/IKavanagh/BingChatInFirefox. It also adds a sidebar that opens when you click the extension icon but copilot doesn't allow iframes anymore :( so it doesn't work.
