Hi, SendKing,

It is likely to be Bug 1121871.

May I have your help?
Can we attach memory footprint chart here as we did on Bug 1121871 ( attachment 8549471 [details] )?

Many thanks.

Is this a regression?

I was able to reproduce the issue on Flame 2.1.

Result: The browser closes when the user taps "极简版".

Environmental Variables:
Device: Flame 2.1
Build ID: 20150309232119
Gaia: 9f2f64bbc9f29edb36f8cbf57d4e0c3f4dee3124
Gecko: c78eec29e8c1
Version: 34.0 (2.1)
Firmware Version: v18D-1
User Agent: Mozilla/5.0 (Mobile; rv:34.0) Gecko/34.0 Firefox/34.0

On Flame 2.0 and v18D-1 Base Image (2.0), the following dialog appears:

"Downloading /storage/sdcard/downloads/A0hjq1VR.part
/storage/sdcard/downloads/A0hjq1VR.part could not be saved, because the source file could not be read. 

Try again later, or contact the server administrator."

Then the notification "Download started" appears, followed by "Download failed". When the user presses "OK" on the dialog, the browser displays the error message:

"Well, this is embarrassing. We tried to display this Web page, but it's not responding."

See the attached screenshot.

From the memory footprint chart, I am not sure why the Browser process was still alive.

My test result is Browser process was killed after I tapped "极简版 (Simple Version)" hyperlink.
Trying to launch browser app and tap the same link again, Browser will download a file (as comment 5 mentioned).

By using the same steps on Firefox OS desktop version, Firefox will download "index.jsp".
There seems to be something wrong with server response.

Anyway, I suggest to add a error handling to prevent this ERROR.
Thanks.

[Blocking Requested - why for this release]:

A legacy bug. Suggest to fix on latest branch.

Not blocking on low memory bugs.
