In bug 1257565 I'll make them forcibly use the XML version. For the future, we need to make sure the tests work with the remote settings version.

Note to self: bug 1129040 removed the users of plugin_clickToPlayAllow.html and -Deny.html, but left the files.

Ditto browser/base/content/test/plugins/plugin_test3.html

Annnnd bug 1307445 removed the only consumer of dom/base/test/chrome/blockNoPlugins.xml without removing that.

Try looks OK though somehow macOS tests are slow to run:

Bug 1549548 - update browser tests for plugin blocking, r?mconley

Beta/Release Uplift Approval Request

• User impact if declined: Missing test coverage on plugins and the remote settings blocklist on 68.

Note: please also consider this a request for the esr68 branch as well, for which it seems there is no bmo flag yet.

• Is this code covered by automated tests?: Yes
• Has the fix been verified in Nightly?: Yes
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: n/a
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): Automated tests only.
• String changes made/needed: nope

Ritu, I don't see an esr68 approval flag, so needinfo'ing you just in case. :-)

Thanks Gijs! Hey Jcristau, are beta uplifts automatically uplifted to esr68? Just want to make sure this fix doesn't miss uplift to ESR68.

I believe beta will be merged to esr68 at least up until the July 1 merge day.
