Firefox is unable to display Ä Ö Ü

Hello there. I have a 'funny' problem since last night. Fierfox in default mode is unable to display Ä Ö Ü on certain websites. It's a fresh installation without any Add-Ons. When entering troubleshooting mode it can display it. So the thing is: something is altering the displaymode of websites betwine modes.

where do I find the variables that do this in the config - or worse in the registry?

So, Firefox did have a Hotfix to 89.0.1

and that fixed the issue.

Type about:preferences#general<enter> in the address bar. Across from fonts and colors, press the Advanced button. On the bottom, turn on Allow Web Sites To Choose Their Own.

Make sure you haven't enabled a High Contrast theme in the OS settings.

Make sure you are not blocking content.

Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Many site issues can be caused by corrupt cookies or cache.

Been there, done that.

Doesn't fix a dime. In Safe mode: Firefox is able to display characters like Ä Ö and Ü In normal mode: Firefox is unable to display anything that is common to the language I speak.

I reset firefox as suggested, but it keeps automatically re-importing the old config. - whoever thought that would be an great idea...


It is possible that the font that is used is broken.

You can right-click and select "Inspect Element" to open the builtin Inspector with this element selected.

You can check in the Rules tab in the right panel in the Inspector what font-family is used for selected text. You can check in the Font tab in the right panel in the Inspector what font is actually used because Firefox might be using a different font than specified by the website.


You can try to disable hardware acceleration in Firefox.

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.


You can also try to set gfx.e10s.font-list.shared = false on the about:config page.

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".


Thank you for your suggestions, but no, that doesn't fix anything. I still can't get them to work in normalmode. Wich brings me to the second thing:

Setting up a new profile just automaticly reimports the old profile - what is going wrong here?
