I need to temporarily disable 302 redirects in Firefox. How can I do this? I tried going to tools > options > advanced > general > check warn me when sites try to redirect or reload the page, but that didn't work, 302 redirects are still followed. Is there anywhere in about:config that I can disable 302 redirects?

May be this will help you out. Link – 0MV1 May 26 '15 at 14:20

call about:config and set network.http.redirection-limit to 0. But you won't be able to access the moved page.

As I don't have Firefox installed right now, and for others benefit - What does changing this setting as advised do? Would hope that the user would get some warning (rather than a blank page) and / or a offer to load the next redirect. – user66001 Jan 19 '13 at 21:21
@user66001 This setting is absolutely useless for end user. It is a limit of redirects before Firefox decides that it got into a redirect loop and stops following redirects. If you set it to 0 you'll get "Firefox decided that it got a redirect which will not end" error message immediately. – hijarian Jun 30 '15 at 17:43
To anyone reading this answer: strictly speaking, this is the solution as OP asked: 302 redirects will stop being followed. But if you actually want manual redirection, then it's not the solution you want. – hijarian Jun 30 '15 at 17:44
Thanks, this is exactly what I (and the OP) was looking for. To anyone not understanding how this setting can help: ask yourself how use the "allow cookies/images/stuff for this website" Firefox actions when you cannot access any page of that domain (always being redirected to another domain). – CDuv Mar 12 at 20:47

Not specific to Firefox, but you could use the Fiddler debugging proxy, and set a breakpoint on the response. Or use a script like (I guess):
