When start firefox all text is hidden. I restart firefox on safe mode and all text was displayed properly. Then I try to turn off all of my addons and restart in normal mode - text is hidden. I decide to reset firefox, but it's do not resolve my problem. For better understanding what is my problem I attached screenshot.

You can try to disable OMTC and leave hardware acceleration in Firefox enabled.

  • about:config page: layers.offmainthreadcomposition.enabled = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can do a font test to see if you can identify corrupted font(s).

You can try different default fonts and temporarily disable website fonts to test the selected default font.
