Firefox hebrew font is often un readable

As a relatively new forum user, you are encouraged to take some time to familiarise yourself with Forum requirements; in particular, the many ways to use the forum to your benefit:

The Update Announcements contain a Known Issues and Solutions section and should generally be checked before posting a request for support.

Output of the following command formatted according to forum requirements (see links above) is often useful (and this or similar will usually be asked for in Support threads):

inxi -zv8

This gives some (privacy-filtered) information about your system.

I can’t see this topic going any further until the volunteers in this forum know what desktop environment you are running, what compositor, and details of your graphics. The output of the above command will provide that information.

Regards.
