Visit: https://wiki.mozilla.org/ReleaseEngineering/How_To/allthethings.json Then visit: https://wiki.mozilla.org/ReleaseEngineering/How_To/allthethings.%6a%73%6f%6e Notice the latter is a real page, (and should be a real page) while the former is served as json by the web server and firefox tries to parse as json. Yes the page could be renamed but I don't think we want real wiki pages able to be served as json anyway...
??? both look normal to me. Content-Type: text/html, looks like a normal wiki page. Checked in Chrome and Firefox Beta. Some addon breaking it for you, maybe? Can anyone else replicate?
I'm on dev edition, so maybe thats the cause? https://developer.mozilla.org/docs/Tools/Valence is listed as an addon in my addons list, and I've not actively chosen to download... let me look again... And it seems that it does indeed serve as ```Content-Type:"text/html; charset=UTF-8"``` so probably an addon/dev-edition issue.
And to be clear, even with Valence disabled, it still has this behavior
I'm also having this issue with Developer Edition (FF45). I came across this while checking https://docs.npmjs.com/files/package.json , which should render as a HTML document, and also contains this header in the response. > Content-Type:"text/html; charset=UTF-8" Thanks for the workaround in the description!
duplicate of this bug 1235725 perhaps?
(In reply to Robert Longson from comment #5) > duplicate of this bug 1235725 perhaps? They are indeed one and the same issue afaict. Not sure which way to dupe though.
I'm arbitrarily duping this forward to bug 1235725, since that bug has a "regression" bug comment and this bug is much noisier for its time spent going around the triage queues.
