Using Brave 0.58.18 on Ubuntu 18.04.1, but likely doesn’t matter.
I’m a big privacy wonk. Previously had been using Firefox’s containers for all the major sites that do tracking (Google, Twitter, Facebook, news sites, etc).
When surfing with Brave, say I have Twitter open in one tab and I’m looking at my feed. As I surf in another Brave tab, a page has a Twitter share button. Does Twitter know I loaded that page? Basically connecting my logged in session with the served image?
I couldn’t find this documented anywhere on how this cross tab privacy works. If it’s written somewhere, please post a link.
I didn’t expect this to work, but it did. I had Twitter logged in on one Brave tab. I then opened another tab to Nuzzel, which uses Twitter for authentication. Logging in to Nuzzel via Twitter was just a click. So I think my Twitter cookies are available to other tabs, and may be when their share images appear on other pages.
