Hello, Elle!
Well done!
You have chosen an excellent browser.
Very fast and no ads!
I am not sure what kind of rubbish you mean?
Is it shortcuts on screen, that you no longer need?
If so, it is very simple to get rid of them.
If it's junk files and stuff clogging the memory, I use an app fro Google Play Store to install and run it, and it cleans out all the junk and old files.
Most of the cleaners are free.
I use "Norton Clean, Junk Removal", but there are many more to choose.
"The Last Hillwalker" is Burns reflecting on his days in the mountains etc. Should be good.
Now the other book is about the voyage of the Fram to the North Pole.
Nansen was an astonishing man.
He was a champion skier, scientist, polar explorer, diplomat, Nobel Prize winner, and created the "Nansen Passport".
I think it will be a great book!
