That seems to me a problem with that site.
But I'm not getting this xml parsing error here, using trunk.
Comment 2 Anna (Waverley) 2011-08-11 03:30:34 PDT
I am also getting this error using trunk. And on the stock browser,  is loading fine.
Comment 3 Aaron Train [:aaronmt] 2011-08-11 06:03:11 PDT
Works for me just fine. Not a Fennec front-end issue.

This is still reproducing, I attached the log and also please see video:

Yes, perhaps this can be reproduced, but this is very likely a problem with gmail, not with Fennec.
Comment 6 Cristian Nicolae (:xti) 2011-08-17 04:44:24 PDT
I've tried to open the Gmail webpage on the stock browser and it has worked fine. I had the same result for a couple of 3rd party browsers. It seems that occurs only for Fennec.
Also I've changed the uagent via Phony add-on and the Gmail webpages has been loaded correctly for all existing options, except the Default one, as you can see here:
I hope that this view-source code it would be helpful:
Comment 7 Martijn Wargers [:mwargers] (not working for Mozilla) 2011-08-17 04:50:24 PDT
It's happening because the ampersand in this link isn't escaped:
<a href="">

So this is a tech evangelism issue.

I wasn't seeing this issue, because I don't see the "New to Gmail? It's free and easy" part. I guess Google knows that I'm already using gmail.
Comment 9 Aaron Train [:aaronmt] 2011-08-17 06:52:09 PDT
Raising severity seeing that Mobile Firefox users can't see nor login to Gmail which is extremely bad.

Comment 16 Mounir Lamouri (:mounir) 2011-09-09 05:16:24 PDT
FWIW, this is definitely because GMail serves another content to Firefox (and Opera). Changing the user agent to the stock Android browser solves the issue. That's really sad...
Comment 17 Chris Lawson (gone) 2011-09-09 05:26:35 PDT
So not only are they browser-sniffing, but they're serving invalid XML to browsers they don't recognize. Lovely.

What will it take for this bug to get looked at and assigned a contact to speak to Google?
Comment 19 Karl Dubost 2011-09-09 06:20:09 PDT
Opera has the same type of issues with a few sites, specifically ASP.

Basically the sensible thing to do is to reparse the page as HTML (common users) and send a warning or error in the log (web developers).
Comment 20 Mounir Lamouri (:mounir) 2011-09-09 06:23:10 PDT
Paul, by any chance, could you point this bug to whom can fix it?

You are assuming that we have not poked Google about this?

Someone should probably file a new bug against Gecko to do exactly that, since throwing up a "this site is broken" page is poor UE compared to "this site is broken, but we'll show it to you anyway".
Comment 23 Peter 2011-09-12 12:01:36 PDT
It seems that many more mobile browsers are having the same problem with Gmail since august 30:
Comment 24 Aaron Train [:aaronmt] 2011-09-15 09:50:53 PDT
I just attempted to login today and this seems fixed; was able to login, compose and read email. Can someone else verify that all is fixed now?
Comment 25 Martijn Wargers [:mwargers] (not working for Mozilla) 2011-09-15 10:01:42 PDT
Yeah, seems fixed. I'm able to login too.
