Blocks instead of font characters for text & numbers.
Hi A newly opened Firefox page has unintelligible blocks for text and numbers. They are multicoloured.. Attached image I have tried in safe mode and same occurs. Looked at Fonts and tried various changes with no success. When firefox opens existing windows and tabs may not have the problem. A new tab such as this one will be ok. Move to new window and problem occurs. But not consistently ok or not. This has been occurring intermittently for some time. Any ideas please? Thanks for your help.

You can try to disable hardware acceleration in Firefox.
- Settings -> General: Performance
remove checkmark: [ ] "Use recommended performance settings"
remove checkmark: [ ] "Use hardware acceleration when available" - https://support.mozilla.org/en-US/kb/performance-settings
Close and restart Firefox after modifying the setting to make changes effective.
You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.
