Is everyone who has gotten this using Firefox Quantum? (Side note- please include browser info when reporting bugs :) )

Given that Firefox Quantum is such a new browser, and it seems to be happening randomly and go away with a page reload, I don't think this is an error on Subeta's end. I would wait to see if it's fixed in the next update of Firefox. If the error persists, I might get in touch with some Mozilla engineers to see if we can get any insight on what the problem is. But tl;dr this is a wontfix for now.

Hmm okay. I have to ask, is there any pattern to it at all, that you notice, as to what pages or types of pages it occurs on? Does it ever happen when you are submitting forms, or only when you are navigating to a new page. And when you get the 400 error, does it just say "400 Bad Request" or is there anything else? (Maybe provide a screenshot?)

Oh, more important questions, I think these will help a lot.

1. Next time you get this error, could you please provide for me the exact URL of the page you get the error on?

2. Can you make sure that you are using HTTPS and not HTTP? I am wondering if it might be related to HTTP (since Firefox seems to have issues automatically correcting it to HTTPS) and if the error might only occur on HTTP.

As for the status code - Anything in the 400s is a "client error" meaning that there was something wrong with what the browser sent to the server (rather than something wrong with how the server responded) Usually 400 Bad Request means that the request had a syntax error, and the most common reason for it is a broken link or a link that has invalid characters. So I hope seeing the exact URL will help in case it's a URL problem, if not we can look at debugging the exact headers to see what is going on.

Thanks. So far I notice reports have only been on these pages:

• Starting a quest
• Buying from NPC main shop
• Scratching a scratchcard Are those it so far? It's interesting, I'm trying to think what those all have in common... Definitely let me know if you notice it on any new pages, or any other changes. And please definitely let me know if you notice it on any browser that is NOT Firefox. I'm still keeping an eye on this but still sorta convinced it's a glitch in the new Firefox.

Please include your browser info when making reports!

Thanks. One more question, have you experienced any similar error on any websites other than Subeta? Or does this seem to be a subeta-specific thing?
