Tested it on Fedora 26 i686. No regression noted.
Tested it on Fedora 26 i686. Work as expected.
Works for me!
The extension is now correctly enabled and loaded. No new issues found.
Overall, I didn't find big issues. Here are the steps I followed in order to ensure a general coverage:
1) Tested general usage. 2) Followed firefox-browse and QA's browser (https://fedoraproject.org/wiki/QA:Testcase_desktop_browser) Test Cases. 3) Submitted a bug via Bugzilla's home page. 4) Tried to print a page to a PDF file.
The only one bug I found is #1431411, but it's not a regression and seem only related to a specific use case (qemu-kvm).
Overall, no issues found on bare metal (old i686 laptop). The kernel regression test fails (https://apps.fedoraproject.org/kerneltest/logs/13491) but, since it failed with the last two kernels too, it's not a "real regression" by this one (perhaps i686 is not fully supported by the suite?).
