Big source / minified files make Chrome Developer Tools freeze
For me blackboxing is not working also. Helps only:
- Kill Chrome process that eats CPU (developer tools will be closed)
- Open any website without huge source files (e.g. ya.ru)
- Switch source tab to another
- Open Developer Tools on the target website (and do not switch to source tab)
Also I do not have this problem on Chrome Canary
This is a known bug: Chromium Bug Tracker - Issue 593679 - [REGRESSION] DevTools: Big sources hang the Developer Tools, and it's currently fixed, but not available on regular/stable Google Chrome or Chromium.
The temporary solution is to use Chrome Canary.
