Hei! My Mozilla updated automatically to the latest version, as usual. Since then, it has become slower in loading webpages. Actually, the most frustrating is the fact that when I have many tabs open, when I change a tab to a one I have already loaded, it tends to reaload it in a way. Is there anything I can do for that? Is there a way to return to the previous version until these problems are resolved? Thank you. Aki
