A browser causing several gigabytes of free space being filled out with duplicate files -
how could they possibly not classify it as a "problem" or a "bug"?
For what I understood from this topic, the folders and files are temporary and are removed when Opera is closed. So for majority of users, this is not exactly an issue.
I don't power off my computer nor close my browser unless it crashes. I don't like bookmarks, I use about 50 tabs across 4-5 windows, thus why I never close it.
I have a whole ton of scoped_cruft dirs and I also am tired of this bug.
