hello IgoRock, you can try this in order to restore the default set of certificates used in firefox: go to firefox > help > troubleshooting information, click on profile folder/show folder and close all firefox windows afterwards. a windows explorer window should open up - in there rename the file named cert8.db into something like oldcert8.db - it will be regenerated again the next time you launch the browser.
