Firefox Problems with Flash
Adobe stopped supporting Flash Player beginning December 31, 2020 and blocked access starting January 12. If Flash is not disabled you could be blocked from webmail or other programs with a message along the lines of “access is not allowed with Flash due to security concerns.”
To disable in Firefox on Windows:
1. Launch Firefox
2. Open the Firefox browser menu (three stacked lines in upper right)
3. Select the Plugins link (Options > Extensions & Themes near bottom > Plugins)
4. Select Shockwave Flash and click Never Activate (or Disable).
