User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0 Build ID: 20160123151951 Steps to reproduce: I tried to print to my dymo 450 printer using an application that is used with firefox. The application ran fine on Monday, but did not work on Tuesday. Actual results: When sending the print request to the printer nothing happens. But if I send a test to the dymo directly from the computer the dymo tests fine. Expected results: The dymo should have printed a prescription label. It did not.
Did you make a test with a fresh profile? https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles If that doesn't change anything, there is a possible regression in FF44. 1) Test Nightly, maybe it's already fixed: https://nightly.mozilla.org/ (you can use a custom profile not necessarily your current profile) https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles 2) As you're able to reproduce the issue on your side, could you install Mozregression to find a regression range. See http://mozilla.github.io/mozregression/ for the details (it's python 2.7 package) Use the command-line version and run the command "mozregression --bits=32 --good=43" and try to reproduce the issue for each nightly downloaded by Mozreg. At the end, copy here the pushlog provided in the console output.
