You can try
chromium-dev as this is not the right group for this topic.
However, I think you better update to the latest Chromium (and always keep it up to date), because Chromium 39 has many, many (hundreds, if not thousands) known security vulnerabilities that can easily be exploited to hack your system and many, many web development bugs that were fixed in later versions.
Note that Chrome developers do not tend to provide any support for such an old version. The code has changed significantly since then.
