1044323 - When network isn't available, t.co/foo can change to www.t.co/foo which doesn't work

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: Awesomescreen, defect, P5)

Description

[Sam Tobin-Hochstadt [:samth]]

If the network isn't available, and thus t.co doesn't resolve, FF will try www.t.co _and_ change the state of the URL bar to have www. However, the www version doesn't work, and thus the tab state is permanently broken and has to be manually edited to work.

Note that the url bar changes happen on Desktop as well, but it's not nearly as big a problem since network connectively is usually better than on a phone.

jduell, can you have someone look into this?

Comment 3

Patrick, do you have any idea if prepending 'www.' to a URI when it fails is a thing that necko does?  I suspect this is higher up in the stack.

Hi Jason,

I did a quick search about this:
http://dxr.mozilla.org/mozilla-central/search?q=browser.fixup.alternate&case=false

It's not related to necko, but I think this could be fixed on Android (or any other platform we need) by setting the browser.fixup.alternate.enabled pref to false.

Also an interesting route - I think we could define the prefix pref as empty string, and this would make the alternate URI being the same as the original URI and thus leading to a retry of the load. Not sure if that's something we should do, but it could be useful in various cases.

:kbrosnan this applies to desktop Firefox as well, but it happens less there, as I said in comment 1.

[Kevin Brosnan [Ex-Mozilla]]

This is filed as an Android bug. Making a clone of it for desktop seems sensible as each product may want to take the fix separately.
