1884394 - Frequent inability to use 'back'

Status: NEW

(Fenix :: Toolbar, defect)

Description

[Randell Jesup [:jesup] (needinfo me)]

Steps to reproduce

1. Browse to a site from an intent (typically from the google news feed, with firefox nightly set as the default browser, and the "open in browser" setting in the google app set (which isn't the default), so that it opens in the browser directly.
2. Normally 'back' takes you back to google news (sometimes sites interject a navigation into history so 'back' initially takes you to lists of their other articles/ads, and back from there goes to the google news app.
3. Sometimes (typically at least once or more a day), back does nothing. The page is responsive. holding back pops up the history list, which always has the same site listed twice. selecting either one doesn't fix it. You have to kill the tab.
4. Selecting the same article again from google news does not have the same issue; back works normally. For this reason I don't think it's the site trying to block back by immediately re-navigating.

Expected behavior

Back works

Actual behavior

Stuck on page

I continue to hit this many times a day...

Note that 'reload' (which works) clears the error, and then Back will go to the right place (which is in the cases I've hit to exit the browser)

Remove Bug 1898059 link, they are similar but unrelated. This issue is a problem with Android OS Back button, not back gesture. Thanks
