802725 - XML Parsing Error after 16 launch

Status: RESOLVED FIXED

(Firefox :: General, defect)

Description

[Matt Grimes [:Matt_G]]

We saw a distinct spike in XML Parsing Error reports for a single day after the 16 launch. The reports have now dropped off completely. You can see the trend here:https://input.mozilla.org/en-US/?product=firefox&version=16.0&date_start=&date_end=&q=XML+Parsing+Error

It seems to be Windows 7 predominantly. Some of posts are almost identical, so it could be a single user skewing the data.

One of the comments says "File pointed: netError.xhtml Line Number 309, Column 54"
http://mxr.mozilla.org/mozilla-release/source/docshell/resources/content/netError.xhtml#309

Perhaps a localization is missing, or has bogus value for, one of the entities
in this file?  Do we have the user's localization in the input data?

All the comments seems to have "Windows 7 English (US)‎" so I'm guessing en-US.

Attachment: error page similar to the one reported

I found several results in google where people saw this error related to some addons like Amazon Toolbar or Speedtest, but the error messages are not exactly the same.

Attached is an error page I get when going to the about:addons page while I unplug the internet connection in this VM and then try to initiate a speedtest. I wonder if I could trigger a TestPilot study which would maybe try to access a resource that is not available and display a similar message under the right circumstances (which I still don't know how to recreate).

Hmm, the entity ref in that screenshot is &netOffline.longDesc;
but l10n-mozilla-release, mozilla-release, -beta, -aurora, -central all use
&netOffline.longDesc2;

http://mxr.mozilla.org/mozilla-release/search?string=ed_netOffline&find=&findi=&filter=^[^\0]*%24&hitlimit=&tree=mozilla-release

Searching for "netOffline.longDesc" reveals some declarations of both:
http://mxr.mozilla.org/l10n-mozilla-release/search?string=netOffline.longDesc&find=&findi=&filter=^[^\0]*%24&hitlimit=&tree=l10n-mozilla-release

e.g.
http://mxr.mozilla.org/l10n-mozilla-release/source/bn-BD/dom/chrome/netError.dtd#28

but there are no "&netOffline.longDesc;" that I can find.
(would have been nice if one could see the file name in that screenshot)

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

CCing Jorge, there are some add-ons which have the old entity, maybe they should be labeled as "not compatible with Firefox 16"

Comment 7

[Jorge Villalobos [:jorgev] (he/him)]

Added to override list:

https://addons.mozilla.org/en-US/firefox/addon/firefix/
https://addons.mozilla.org/en-US/firefox/addon/bandwidth-meter-and-diagnostic/
https://addons.mozilla.org/en-US/firefox/addon/domain-lookup/
https://addons.mozilla.org/en-US/firefox/addon/go2-proxy/

I also contacted the developers.

Judging by what I've seen in add-on code, "&netOffline.longDesc2;" has been in use for a while, and "&netOffline.longDesc;" was removed just now in Firefox 16. Some add-ons didn't update to the new string and then broke.

This is as much as we can do for add-on compat, so maybe this bug can be closed.

Not sure if this should be marked as fixed, but it's definitely not relevant anymore.
