Good morning, I was working this morning on the browser when suddenly the webpage I was in showed a connectivity error. When I tried reloading the page it did not load at all. I have tried with many other websites and none of them loads. I have tried waiting to see whether an error appeared, but nothing. Whenever I try to close the browser after a while (approximately a minute) it shows an error message that the process has crashed. I have already sent the report a couple of times before quitting the process from within the error message. I run a Dual Boot system of Windows 10/Ubuntu 20.04 I am only experiencing the problem with firefox in Ubuntu and other browsers work correctly on the system. I have re-installed firefox with "sudo apt remove firefox" and "sudo apt install firefox" and nothing changed. I have also updated to the latest version, tried disabling all the add-ons and switching the connection to "no-proxy" as suggested in the support webpage. I don't really know what else to try Thanks in advance for the reply and do not hesitate to ask for any further information you may require.
