User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20171211020921

Steps to reproduce:

Debug a page with different response content when a GET param is present 
example if
http://example.com/index?var=xxxx 
and 
http://example.com/index
response content differs




Actual results:

When visit page with url http://example.com/index?var=xxxx  
Show code for http://example.com/index


Expected results:

if you visit http://example.com/index
in debuger must shows the code for http://example.com/index

when you visit http://example.com/index?someParam=xxxx
debugger must shows the code for http://example.com/index?someParam=xxxx

I don't see a bug here (yet). One page title is "ShuttleWizard.com :: Reservation2", the other is "Administration - Login". 
Hence different pages delivered. If it's not different pages delivered then please provide a public testcase. Thanks!

thats the bug. Debugger show same code for urls with diferent GET params

https://links.nextor.mx/test/?xx=0
shows alert with hello
https://links.nextor.mx/test/?xx=1
Show alert with there

https://links.nextor.mx/test/?xx=0 on inspector shows code for hello
https://links.nextor.mx/test/?xx=1 on inspector shows code for there

https://links.nextor.mx/test/?xx=0 on debuger shows code for hello
https://links.nextor.mx/test/?xx=1 on debugger shows code for hello


I was able to resume my work by disabling the cache, even though I think it is a minor bug

thats the bug. "Debugger shows same code for urls with diferent GET params"
another point of view is "Debugger shows different code in  Inspector and debugger for the same page"  when you already visit previous page with diferent GET params
if you are debuggin you can't see the current code that is in the runtime

In the zip the two images correspond to the same page, in inspector and in debugger
the code must be the same, but differs.

In the second post i made a test case.
the screenshot shows the diference between the runtime and the code displayed in debugger 

for simple pages disabling cache fix my problem but for complex pages my problem persist.

Thanks for the clear example. This fails for me as well.

Brian, could you investigate this? I think we've seen similar reports to this one, but this has the clearest STR I've seen.

Brian, assigning you for planning purposes. Feel free to pass it back.

Sylvester, we're using the status field to track whether something is in progress

The links in comment 2 don't work anymore, unfortunately. This sounds like a problem with fetch() returning the wrong results, in which case it would be a similar problem to bug 1375036. The analysis in comment 16 of that bug should apply here as well.

Comment 9

[Jason Laster [:jlast]]

I agree with your assessment that this should be fixed via bug 1375036.

Did you try comment 2?

These two links for me when the cache was disabled via the net monitor
https://links.nextor.mx/test/?xx=0
https://links.nextor.mx/test/?xx=1

It seems like a good test case

This was fixed via bug 1538056.
