Steps to reproduce:

i have open a site(this is not care fake or original) and i try to download a file (i search for download a file) but site redirect me into pages and when i try to to back site never allow me to back first place and site repeatedly redirect me into fake pages and only way to back use history but issue won't fix, also i forgot the site name. any one know please add here .

Actual results:

one of the most annoying things on the internet is websites that hijack your browser. Unfortunately, this isn’t something exclusive to shady websites. You’ve probably run across a legitimate website that doesn’t let you go to the previous page when you click the Back button.

You search for something on Google, bing, etc and select a result, but you realize it’s not what you were looking for. When you click the Back button to leave the website it simply refreshes the page or refuses to go back. The only way to leave the page is to mash the Back button repeatedly or open your History and select the previous page.

Expected results:

please combating these “history manipulation” tactics. That’s how these websites prevent you from leaving with the Back button. They manipulate your browsing history so going “Back” doesn’t go where you expect.

Mark entries to be skipped on back for history manipulation intervention.

Entries that are added to the back/forward list without the user's intention
are marked to be skipped on subsequent back button invocations.
This CL only adds the bit and subsequent CLs will add metrics and the intervention
logic based on this bit.

This seems related to/block bug 1645211. Let's revisit this after that bug.

The bug has a release status flag that shows some version of Firefox is affected, thus it will be considered confirmed.
