After Firefox automatically updated two months ago, non stop problem with PR_END_OF_FILE_ERROR, connection problem when trying to open web pages that always opened before. I have never had this problem before, have tried all troubleshooting and online solutions but nothing has worked. How do I fix this problem? Thank You,

Best Regards

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

cor-el said This usually means that Firefox wasn't able to find a cipher suites to use to connect to this server and reached the end of the list. There can be two possibilities: one is that the server is outdated and doesn't support modern cipher suites, another might be that the server only supports a few cipher suites and Firefox doesn't support any of these.

You can check your browser and possibly compare this with the server setup.
