Why is BrowsePass really, REALLY, slow?
Why is BrowsePass asking for permission to read and change all your data on the websites you visit?
BrowsePass supports Google Drive, and other WebDAV-based file hosting services. To do that, it has to make HTTP requests and read the responses.
BrowsePass never reads nor changes your data, unless you tell it to. For example, if you ask BrowsePass to open a file from a WebDAV source, it has to read that file. BrowsePass never changes any data. It is read-only.

Why does BrowsePass not remember the last URL?
BrowsePass never changes any data and therefore it cannot remember anything.
