Privacy Browser Android

https://developer.android.com/reference/android/webkit/WebSettings.html#setSupportMultipleWindows(boolean) might be one way to implement.

I've seen tabbed browsing implemented in a few different ways, but I'm not sure which I like better.

Lightning uses a tab drawer that you swipe open from the side or press a numeric button in the upper corner to access.
Peregrine has a horizontal scroll of tabs on the bottom of the screen.
Chrome and CAF browsers have a vertical "tab stack" that you can access by pressing a numeric button at the top of the screen.

All three are pretty nice, but Peregrine's implementation has the easiest method to create and remove new tabs, with the trade-off of taking up screen real-estate that the other methods don't have.

My plan is to use a `TabView`, similar to those in the Guide and About sections of the app.

I like that. Will there be tab controls (new and close) on there, as well? Also, any chance of getting the priority on this one increased, or will you keep it at low due to the effort (I'm assuming) required to implement tabs?

There will be controls to create and close tabs, although I haven't yet finalized where they will be in the interface.

I anticipate that it will a significant amount of work to implement a `TabView` and integrate it with the rest of Privacy Browser. For more information on the timeline, see https://www.stoutner.com/category/roadmap/.

Whats the difference between your proposed implementation and using chrome custom tabs?

Is it imperative to create a hack for finer grained privacy?

I recently encountered accounts.google.com disallowing authentication with useragent WebView. It seems this was not the intended purpose.

Chrome custom tabs opens up a tab using Google Chrome but allows the developer some control over how the UI looks so they can integrate it in their apps. As such, it has all of the privacy downsides of using Chrome. For example, from the description in the link:

1. "The browser uses Google's Safe Browsing to protect the user and the device from dangerous sites" - a list of every website you visit is sent to Google so they can spy on what you are doing.
2. "Providing a likely URL in advance to the browser, which may perform speculative work, speeding up page load time" - Google keeps track of everything you type in the URL bar, even if you don't load it.
3. "Shared cookie jar and permissions model so users don't have to log in to sites they are already connected to, or re-grant permissions they have already granted" - Google gets a copy of all your cookies.
4. "Synchronized AutoComplete across devices for better form completion" - Google saves a copy of everything you type on a webpage.

"I recently encountered accounts.google.com disallowing authentication with useragent WebView. It seems this was not the intended purpose."

I assume that this is a question about how to log into Google web pages using Privacy Browser. The following steps work for me.

1. Create domain settings for "*.google.com". It is important to use a wildcard subdomain as Google loads accounts.google.com for authentication but then moves back to a different subdomain to display content.
2. Enable JavaScript, first-party cookies, and (possibly) DOM storage for the domain.
3. Depending on which Google web page is being visited, set the user agent to WebView default. For more information, see https://www.stoutner.com/user-agent-problems/.

Look at using a tab custom view for displaying icons.

The topic of user agents has nothing to do with tabbed browsing, but you can find a fair amount of information about it at:
