How to bookmark an automatically redirecting link on the Android? I am on page_1. There is a link_1 to page_2 that redirects to a random URL page_x. I cannot go to page_2 because I will not see its URL in the address bar (it redirects to page_x)

I want to bookmark link_1. On a non-mobile browser, I would right click link_1 and bookmark it.

I am using the pre-installed "Internet" browser that comes with the Android. How do I bookmark link_1 on Android?
I'm not sure I entirely understood the scenario you're describing, but a similar function to right-click->bookmark on Android would be to do a long press on the link, then choose Bookmark link. This should bookmark the link as it exists on the page, regardless of where it eventually sends you.
