Guidelines for filing good bug reports

Opera’s developers are interested in learning about every reproducible, specific bug found in the Opera browsers. Please note, however, that incomplete or inaccurate reports waste valuable time. More bugs will be handled more quickly if you follow these guidelines when submitting or considering to submit a bug report.

Put in as much relevant detail as you can. (If you are not sure about the relevancy, include the detail.) Be as specific as possible. Please make sure that you can reproduce the bug before reporting it.

Multiple problems should not go in one bug report; if you have seen more than one problem, please keep each one distinct and separate, filing another report if necessary.

Please include your e-mail address. Sometimes, it is necessary to write to you to get additional details, and we cannot do that if you have not given us a way to contact you. Also, it makes it easy to locate all the bugs you have reported, but unfortunately, that search option is not available to us if you have omitted your e-mail address.

Please look over your report before pressing the “Submit” button.

FRBs (Frequently Reported Bugs)

If your bug is being discussed in the My Opera community forums, the Opera newsgroups, or the Opera-users mailing list, then a report has more than likely already been filed, and any report you file will be marked as a duplicate. This wastes time for both you as reporter and us in classifying the report as a duplicate.

Include an URL

Include the URL of a page that demonstrates the bug. This inclusion is probably the most critical to ascertain whether the bug is reproducible. Unless your bug report is for a component which by its nature cannot have a URL, such as the e-mail client, then please include one in the text area provided. Include all components of the URL, like this: http://www.example.com/thisone.html

Language

The preferred language for bug reports is English. If you file a bug report in another language, we will do our best to find someone to translate your report. Note that this process may take valuable time away from actually fixing bugs which are reported in the preferred language.

If the URL provided is for a non-English page, please provide enough details about the page to make additional translation in order to understand the bug unnecessary.

Severity

Crashes my computer
One of the most serious types of bugs, this simply means that your computer becomes unusable when this type of bug is encountered.
Crashes Opera
Although Opera becomes unusable after this bug is encountered, the computer itself seems unaffected.
Spec violation
Opera is performing contrary to published, interworking recommendations by the W3C.
Other severe
Although not a crash bug, nor a spec violation, the nature of the bug should be considered severe enough to warrant a fix before the next build.
Significant
Although not a crash bug, nor a spec violation, it should probably warrant a fix before the next release.
Trivial
While not at all critical, Opera’s behavior under these circumstances bothers you.
Enhancement
Avoid this category as far as possible, and note that feature requests should be handled via the customer questionnaire as feedback.
