Launch Firefox. 2. Access the about:support page. 3. Press CTRL + P in order to open the Print Menu. 4. Click on Print. 5. Redo Steps 3 & 4. **Expected result** * The about:support page is successfully printed. **Actual result** * Step 3: Nothing happens (for both print to file/pdf or starting an actual print job). * Step 5: The following error is shown: `Some printing functionality is not currently available`. **Regression Range** This seems to be a regression * Pushlog:https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=40ca68bfea62e27f6934d4327f1ff88df9c17828&tochange=4c92802939c15a2356c587d247577e07cfb52ff7 * Regressed by: Bug 1552966 **Notes** * macOS has a different behavior (I’m going to log a bug for it shortly and link to it here and update this comment as well). * Printing the page via print preview seems to work as expected. * After triggering this issue navigation from about:support to any other local page (about:cache,etc) seems to no longer work. A workaround for this is opening another tab and accessing the local page or from within the same broken tab accessing a remote website and then a local page. * The Browser Console outputs the following error: `In Printing:Print:Done handler, got unexpected rv 2147746065. 2 PrintingChild.jsm:403` * At first try it will not print and the error is displayed, at second try (in a new tab or after accessing a remote page and going back) it will print but printing again after a successful print seems to no longer work again.
