Hello I am German and not used to write in english. I use Firefox on my Xperia device. Within the last Update I got the new function to collect the tabs. I created several collections and named them. After I put in the tabs and deleted them in the list. So they were only in the collections. Today I wanted to use one Tab out of the collection. But the whole collection Was not any more there, same with 2 Others! Where are these collections and the tabs now? I did not delete them and I need them! How does it happen and why is it possible? How do I get all of them back? Mischa
