Hello, the problem with Firefox is that it loads the pages too slow, other browsers such as Chrome or Opera are working correctly. At first everything was fine but suddenly Firefox started to take forever to load the pages. I have completely uninstalled Firefox and installed it again but the problem persists. I thought it was a problem with some extension (I only use AdBlocker and HttpsEverywhere) but restarting it in safe mode the problem persists. I also have to mention that the Ubuntu installation is recent. What could be the problem?. I am using Ubuntu 18.04.5 LTS.
