[Affected versions]: Firefox 63.0a1 (BuildId:20180903220141) [Affected platforms]: Windows 10 64bit. Ubuntu 16.04 64bit. macOS 10.12.6 [Steps to reproduce]: 1. Launch Firefox. 2. Access the about:policies page. 3. Enter the following link inside the address bar and press enter: about:policies#documentation [Expected result]: The about:policies#documentation page is displayed. [Actual result]: The about:policies#active page is displayed. [Notes] For further information regarding this issue please observe the attached screencast. It seems that the pages are not changed via address bar if the about:policies page is displayed inside the same tab (from where the search is performed). This issue is reproducible with all about:policies pages. Please note that if the about:policies page is not displayed (inside the tab from where the search is performed), the search for a certain about:policies page is successfully performed via address bar. This may be an Edge case scenario since the users will, probably, navigate through about:policies pages through section links.

Hi, I can reproduce the problem and I'd like to work on this bug if anyone can guide me through it.

Hi Yushan, do you have experience with web development? This bug will involve a bit of JS and event listeners. First, to get started, you'll need to check out a copy of the Firefox source code from Mercurial: https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Source_Code/Mercurial) Then you need to be set up the build environment to compile/build it. Since to fix this bug it won't be necessary to recompile any binary components for Firefox, I recommend setting up an artifact build which is much faster and easier to use: https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Artifact_builds

Hi Felipe, I have Firefox built. I think I found a fix for the problem.

When you've got a patch for it, you can attach the diff here in bugzilla, or you can submit it through Phabricator (https://moz-conduit.readthedocs.io/en/latest/phabricator-user.html) Feel free to describe the solution you've found here so I can advise if it's on the right path

In mozilla-central/browser/components/enterprisepolicies/content/aboutPolicies.js I added a window.onhashchange to check if the location hash of the url has been changed. If there is a change, the page will change based on the location hash that was given.

awesome, yeah! Just use addEventListener("hashchange", ...) instead of setting window.onhashchange = ..., as that's our preferred style

I attached the patch for this bug. Let me know if there's any changes needed!

Thanks for the patch, Yushan! Sorry for the delay, I had not noticed the patch in the bug, because usually when we attach a patch it's also expected to choose a reviewer, which will get notified about it. Anyways, the patch looked good, so I just pushed it. Thanks for your contribution!
