**Is this a…** :
Standard bug
**Steps to reproduce this issue** :
Visiting WME on Firefox in Normal or Private Browsing (no add-ons, no scripts) causes extremely slow performance. When panning the map with only the segments layer selected segments take 10+ seconds to load. I’m not positive this is a bug with WME or Firefox, but thought I’d bring it up!
Firefox Console is spamming:
Content-Security-Policy: The page’s settings blocked an event handler (script-src-attr) from being executed because it violates the following directive: “script-src ‘nonce-a4418e2c12b2556bea83a8443e090342’ ‘strict-dynamic’ [https://wme-staging-frontend-assets.storage.googleapis.com](https://wme-staging-frontend-assets.storage.googleapis.com) [https://web-assets.waze.com](https://web-assets.waze.com)”. Consider using a hash (‘sha256-i+qr4lq34KgNHiW62lWi9aInEBwiEOrfCzaNPCvkqD8=’) together with ‘unsafe-hashes’. third\_party-6748d42fe3343418.js.gz:2:4136328

Hi @brikowski,
May I ask you for an assistance: Could you please record a performance profile for the web page using Firefox?
It would really help us investigate the issue further. You can follow the steps described in this guide:

Thank you in advance!
