Reading the Boston Globe ePaper causes the tab to temporarily freeze when one navigates (moves/zooms). This is easy to reproduce on a Surface Pro using touch and does not occur in IE and Chrome. This occurs also in the Nightly build fix indicated by https://bugzilla.mozilla.org/show_bug.cgi?id=1446904. This also occurs in safe mode. The ePaper (perhaps there is a free sample) can be found via: http://www.bostonglobe.com/todayspaper Richard ----- Application Basics ------------------ Name: Firefox Version: 61.0a1 Build ID: 20180405193909 Update Channel: default User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0 OS: Windows_NT 10.0 Multiprocess Windows: 1/1 (Enabled by default) Web Content Processes: 3/4 Enterprise Policies: Inactive Google Key: Found Mozilla Location Service Key: Found Safe Mode: true Crash Reports for the Last 3 Days --------------------------------- All Crash Reports Nightly Features -------------------------------------- Name: Activity Stream Version: 2018.03.29.1163-6170061b ID: [email protected] Name: Application Update Service Helper Version: 2.0 ID: [email protected] Name: Firefox Screenshots Version: 30.1.0 ID: [email protected] Name: Follow-on Search Telemetry Version: 0.9.6 ID: [email protected] Name: Form Autofill Version: 1.0 ID: [email protected] Name: Photon onboarding Version: 1.0 ID: [email protected] Name: Pocket Version: 1.0.5 ID: [email protected] Name: Presentation Version: 1.0.0 ID: [email protected] Name: Web Compat Version: 1.1 ID: [email protected] Name: WebCompat Reporter Version: 1.0.0 ID: [email protected] Extensions ---------- Name: Adblock Plus Version: 3.0.2 Enabled: false ID: {d10d0bf8-f5b5-c8b4-a8b2-2b9879e08c5d} Name: Gecko Profiler Version: 0.19 Enabled: false ID: [email protected] Name: Google Analytics Opt-out Add-on (by Google) Version: 1.0.7 Enabled: false ID: {6d96bb5e-1175-4ebf-8ab5-5f56f1c79f65} Name: Kee Version: 2.3.19.1 Enabled: false ID: [email protected] Name: New Tab Override Version: 12.0.0 Enabled: false ID: [email protected] Name: Open in IE Version: 0.2.0 Enabled: false ID: {5610edea-88c1-4370-b93d-86aa131971d1} Security Software ----------------- Type: Windows Defender Antivirus Type: Windows Defender Antivirus Type: Windows Firewall Graphics -------- Features Compositing: Basic Asynchronous Pan/Zoom: wheel input enabled; touch input enabled; scrollbar drag enabled; keyboard enabled; autoscroll enabled WebGL 1 Driver WSI Info: - WebGL 1 Driver Renderer: WebGL is currently disabled.
