I want to change the default timeout in Chrome. In Firefox I can set the value of network.http.connection-timeout in about:config - but how can I do that in Chrome?

This question came from our site for professional and enthusiast programmers.

  • In case anyone comes here wondering how to simulate XHR connection errors while developing web apps, you can use device mode to do so. – Jannik Jochem Apr 13 '15 at 7:50
  • Note that newer versions of Firefox no longer use that configuration. It also uses the system-level configuration which can be changed as mentioned in NOSUKE's answer. – ADTC Oct 21 '17 at 22:31

You can't. Google has been ignoring requests to implement this feature for over six years, so I wouldn't hold your breath.

  • WOW. That is why Chrome should not be the dominant Browser. Just because Google does not like something, they should not be able to prevent it. – Blackbam Mar 7 '18 at 12:51

It's hopeless. They just won't do anything about enabling users to change Chrome's timeout settings. But you could switch to any of four other Gecko-based browsers in common use that have no timeout problems. Or you could start using one of the Mozilla-based browsers.

    I was tempted to mark this as "not an answer", but I realized that you are suggesting an alternative solution. I would suggest editing it and indicating that so others aren't tempted to downvote or flag it. – Moses Sep 12 '13 at 19:05

    Mozilla is Gecko based.... WebKit / Blink (Google's WebKit fork) is probably what you meant? – Gert van den Berg Feb 2 '17 at 19:11

I dealt with this issue by editing the registry. I think the registry affects not only IE but also Chrome in Windows 10. I tried extend time-out. then I can extend it and max time-out is about 7Hrs in my case.

Reference: Microsoft Support

Click Start or press Win-R to get Run box, type regedit, and then click OK.

Locate and then click the following key in the registry:


On the Edit menu, point to New, and then click DWORD Value.

Type KeepAliveTimeout, and then press Enter.

On the Edit menu, click Modify.

Type the appropriate time-out value (in milliseconds), and then click OK. For example, to set the time-out value to two minutes, type 120000.

Make another DWORD value ServerInfoTimeout and set it to the same value.

Restart machine.

  • As of today, this doesn't seem to work – Shayn Dec 14 '17 at 20:50
