First let me thank you for downloading and trying QupZilla!

(1) General

Although QupZilla is considered to be stable, it might happen, that you experience a problem while using it under very individual conditions. If this is the case we kindly ask you to check the following points first, before you open an issue:

  1. Make sure, that you have installed the latest QupZilla release.
    For QtWebkit-Engine: Version 1.8.9, released November 11, 2015
    For QtWebEngine: Version 2.0.2, released October 24, 2016

  2. Create a fresh profile (Preferences->General->Profiles), restart QupZilla and check if your issue still appears.

  3. Ensure, that your issue is reproducible!

  4. Have a look at the FAQ and check, if your issue is described here and provides you a proper solution.

  5. Search within the already filed issues for the same or a similar issue and a solution respectively.

If neither works, please open an issue here and provide the following information:

(2) What steps will reproduce the problem?

To identify your problem quickly, please briefly describe the procedure and steps that will lead to your problem.

Example description:

  1. Start QupZilla

  2. Open link http://yourlink.xyz

  3. Click on symbol ABC

  4. QupZilla does not work as expected

(3) What is the expected behaviour? What do you see instead?

Please let us know, what should happen when you perform the action described above.

(4) What version of the application are you using? Which operating system?

Please select Help -> Configuration Information and paste the contents of this page into your bug report.


Configuration Information

(5) Please provide any additional information below.

It will help us also, if you run QupZilla in a terminal window and paste the output into the bug report. For doing this please refer to the FAQ and have a look at the topics

  • How can I get command line output in Windows?

  • How can I debug QupZilla in case of crash?

(6) Upstream Bugs

After analyzing your issue we might come to the result, that you are affected by an upstream bug. In this case the root cause lies in the Qt framework. We will not patch the Qt libraries to fix your specific issue, but we will file an upstream bug for it under the following circumstances:

  • Your issue is 100% reproducible
  • A detailed step-by-step procedure exists
  • Your issue can be reproduced with QtTestBrowser
  • A recent Qt-version (currently 5.4) is affected

We want to make sure, that QupZilla users will not have to suffer from a poor browsing experience. Thus, we are interested in getting upstream bugs solved quickly. But we will have to enable the Qt-developers to find the reason for the specific issue. This makes a detailed and reproducible bug report mandatory.

The following table reveals the QupZilla issues and their corresponding upstream bug:
