Hi. Could you write the bug report in English.

Steps to reproduce: Go to: http://www.firefox.com/about/contact/ Open the debug tool, some of the Chinese text is distorted When visiting other Chinese websites, also encountered such a mistake. Actual results: Go to: http://www.firefox.com/about/contact/ Open the debug tool, some of the Chinese text is distorted Expected results: Text should not be distorted in debug, because the text does not appear distorted in page.

Thanks Yamin for the attachment, I tested on Win 7 x64 with FF Nighlty 53.0a1(2016-01-05) zh-CN build and I can reproduce it, see the attachement. I also tried with an US build and I can't reproduce it. Steps: 1. Go to: http://www.firefox.com/about/contact/ 2. Go to Tools -> Web Developers -> Toggle Tools -> Networking (reload the page from step 1 and select /about/contact/) -> in the right side go to Response.

I was testing this with patch from bug 1317651 applied and the problem seems to be fixed. Needs to be re-tested as soon as that patch lands in Nightly. Honza
