See Epic: T384758: [Epic] Add Tabbed Browsing to the iOS App (Tabs)

Requirements

• Users can open articles in new tabs and go to them, or open them in the background for reading later
• Update the long-press contextual menu across the app to add two new options
  • ‘Open in new tab’ (opens article link in new tab, and takes the user there)
  • ‘Open in new background tab’ (opens article link in new tab, and does NOT take the user there)
  • These two options always open the article in a new tab (regardless of whether an item is already open).
• Keep current behavior in when navigating links in articles with a short press
• Update the default behavior for opening articles with a short press
  • Web browser:
    • Article opens in new tab, user is taken there.
    • If the tab limit is reached (500), the article opens in the current tab.
  • Search input (anywhere in the app)
    • Article opens in the current tab, user is taken there
  • Explore:
    • Article opens in the current tab, user is taken there.
  • Places:
    • Article opens in the current tab, user is taken there.
  • Saved:
    • Article opens in the current tab, user is taken there.
  • History
    • Article opens in the current tab, user is taken there.
  • Anywhere else:
    • Article opens in the current tab, user is taken there.

Nice to have & will be done in a separate task if time

• Switch to existing tabs when an article is already open, instead of opening a new one
  • For web browsers: If the article is open at the top of an existing tab, switch to it
  • For in-app search (anywhere in the app): If the article is open at the top of an existing tab, switch to it

Designs (Figma)

Updated contextual menu

• We aren’t complicating things for existing users who haven’t dealt with tabs before. Tabs are here when you use them, but stay out of the way if you don’t.

Engineering Notes

• Check the tabs data controller to ensure feature is available. (Will be the same developer settings check as the overview entry point for now, eventually we will add a/b testing logic as a part of T390984). If it is available, add "Open in new tab" and "Open in new background tab" options to ArticlePeekPreviewViewController.
• When "Open in background tab" is tapped, we will tell data controller to add article to a brand new tab (method will already be available to call from work in T392916)
• When "Open in new tab" is called, create an ArticleCoordinator with the new article and tell it to start. ArticleCoordinator will be instantiated with "add to current tab" boolean. (this will already be available from work in T392917)
• All other requirements should already be handled from work in T392917
