793890 - Firefox for Android fails Acid 3 test with "YOU SHOULD NOT SEE THIS AT ALL"

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: General, defect)

Description

[Matt Brubeck (:mbrubeck)]

In Firefox for Android 15 (release) through 18 (nightly), http://acid3.acidtests.org/ gives a score of 100 but the rendering includes red text in the top left corner that says "YOU SHOULD NOT SEE THIS AT ALL". (I did not test any other versions.)

Possibly related, there are some reports of desktop Firefox failing in the same way; see bug 560089 and bug 752637.  It may be related to :visited link styling.

This also happens on the released version of firefox for Android, 15.0.1.

[Kurt Roeckx]

This is a duplicate of bug 752637 and not specific to android?

Comment 3

[Carl]

It seems to be related to it because I don't see that text on the windows 7 version of firefox 15.0.1.

David, do you know why this is failing?

I don't know why it's failing; somebody would need to debug it.  (The best debugging technique might or might not involve simplifying the testcase.)

Though it looks like the underlying problem is that the link isn't considered visited.

Is there a difference in when pages are marked as visited in the global history for Android, relative to desktop?

I got the same error message after enabling e11s in a clean profile on my Nightly build.

Richard do you know the answer to dbaron's question?

[Richard Newman [:rnewman]]

We don't use Places on Android, so there might well be a difference. Link visiting is a Java-related thing:

Possible culprits:

* Difference in CanAddURI implementation?
* 100msec batching delay.
* Race condition?
