I'm having character encoding problems in Twitter DMs...?

[Bolt Disney]

I don't know if this has happened before, but characters like the following " < > & and other special characters have been showing up in weird codes in my direct messages on Twitter. For example, the quotation marks appear as & quot ; (however, without the spaces). I don't know how to fix it and it's really bothering me. Oddly enough, however, I only have this problem in my direct messages on Twitter. Everywhere else is completely fine, even in regular tweets. It's just in the direct messages. Has this ever happened to anyone before? If it has, can someone please give me a simple way to fix it? It's very annoying. I've tried updating Firefox thinking that had something to do with it, but it didn't help. I'm not sure what to do and I have a very poor understanding of this kind of thing, so if anyone could help me with a simple explanation, it would be greatly appreciated.

Update the browser to the latest version to get things fixed.
