1426069 - Netmonitor Performance Analysis does not work in Firefox 58

Status: RESOLVED DUPLICATE of bug 1372115

(DevTools :: Netmonitor, defect, P2)

Description

[magicp]

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:58.0) Gecko/20100101 Firefox/58.0 ID:20171211020921

Steps to reproduce:
1. Launch Firefox 58.0b11
2. Go to Getting Started ("https://support.mozilla.org/en-US/kb/get-started-firefox-overview-main-features")
3. Open Netmonitor (Ctrl+Shift+E)
4. Start performance analysis

Actual results:
Loading does not end and the following error is logged in the browser console.

NS_ERROR_INVALID_CONTENT_ENCODING: Component returned failure code: 0x804b001b (NS_ERROR_INVALID_CONTENT_ENCODING) [nsIStreamListener.onDataAvailable] network-monitor.js:658

When "dom.script_loader.bytecode_cache.enabled" = false, it works fine without error. Nightly works fine even if this setting is true.

Expected results:
"dom.script_loader.bytecode_cache.enabled" = true is default in Firefox 58. Is this intentional?

Thanks for the report, I can reproduce it on my machine.

I am also seeing:
TypeError: can't access dead object tab.js:1647:1
view-source:resource://devtools/server/actors/tab.js


> NS_ERROR_INVALID_CONTENT_ENCODING: Component returned failure code:
> 0x804b001b (NS_ERROR_INVALID_CONTENT_ENCODING)
> [nsIStreamListener.onDataAvailable] network-monitor.js:658
It's related to:
view-source:resource://devtools/shared/webconsole/network-monitor.js
(the actual line in m-c is 679)

Alex, any tips what could be wrong on the back-end?
