Nevermind, I think I just remembered you're on PTO. Hopefully Aaron can help out here.

George, does this look related your skia font wrapping?
Second to last beta coming up, would love to find out if there's anything low risk we can do before Wednesday.
Unsure how duping a bug cleared all those flags...

Created attachment 817214 [details] Better screen shot The text inside the Flash chart is not displayed correctly.
I can't get a regression range due to bug 890272 a Flash crash on activation from July-3 till July-17 where bug 890272 was fixed. This was introduced somewhere in that two week period.
We'll track, but this is looking more and more like a wontfix for FF25. Hoping George Wright can take a look and compare to a Desktop flash instance of the same, for reproducibility.
Worth a relnote? "Text in Flash elements may display as boxes on Samsung devices."
George - is this on your radar for the upcoming week or two? Firefox 26 is in beta now and while this has already shipped in FF25 it would still be good to get a fix given the popularity of Samsung devices.
Sure, I'll look at it tomorrow.
Update, I carried out a complete wipe of my Galaxy S3 and installed FF25 and flash 22.214.171.124 and the problem had gone. I then installed FF26 and all still fine. I then did an official OS upgrade to Jelly Bean 4.3 and all was still fine. I can not pin point it but it is almost certainly a 3rd party app causing this behaviour, I am working my way 1 app at a time to try and find it.

Any update on comment 15?
Not really, I couldn't reproduce it on my device :( Can I get detailed steps to reproduce?

Also there's no way that patch is causing this regression. It's likely caused by a related patch, though, which was to update Skia.
I can reproduce this on a Nexus 4 running Android 4.3 and a HTC t-mobile G2 among other phones. Yes I made a slight mistake in the bisect, the issue lies between http://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=5f652fba751d&tochange=28957db0a941
OK great, I will get a nexus 4 then :)
We're now past the point of taking speculative fixes for FF26 or waiting for George to get a device and investigate. Not marking this tracking for FF27, but a low risk uplift might be considered so please nominate when there's a patch.
This is an common issue in the support forums.
Any chance of getting this fixed on Firefox 27? This is a very visible regression.
So here's the problem - we are currently updating our in-tree version of Skia as the one we are currently using is seriously old. The fix for this would be different on the old Skia vs. the new Skia, and I'd have to fix it anyway with the new Skia (which is what I was planning on doing). As far as I'm aware, there is no plan right now to land the new Skia on 27 (I believe we're targeting 28), and given our limited team resources I'm not too fond of fixing this same issue twice on different Skia revisions, as all the font management code has changed upstream. What do we want to do here? Would it be completely crazy to try and target the Skia update for 27?
George is going to investigate a "non upstream update of Skia" solution. Doing a full update in Beta (or even Aurora) is not the safest approach, but neither is letting this bug stay in the released product for six months. Keep you posted.
NI on George to see if there are any updates here given we are only a few beta's away before Firefox 27 is shipped ?
I have a hacky fix. It's not ideal but it'll serve to bridge the gap until we can find a more optimal/permanent solution.

Already spoke to Milan offline about this, but posting the reply here for all to see; current skia doesn't fix this issue and in fact makes it worse, as the font code has mostly been refactored upstream. Until we assess the extent of the changes and how it affects font selection on Android, we don't know what the optimal solution will be. My guess is that it will be either to fix the Linux fonthost that is maintained upstream to do font selection the way we'd like it to be done, or implement the skia-npapi ANPTypeface methods using gfxFont then returning an SkTypeface wrapping the cairo_font_face_t that is returned.

Verified fixed using Nexus 4 (Android 4.4.2) on: 27.0 Beta 9 (2014-01-24) Nightly 29.0a1 (2014-01-23) Aurora 28.0a2 (2014-01-23)
>Verified fixed using Nexus 4 (Android 4.4.2) on: > 27.0 Beta 9 (2014-01-24) I wander since this is before the merge date isn't this fixed/or should be, in current (mobile) Firefox and https://www.mozilla.org/en-US/mobile/27.0/releasenotes/ needs to be updated? I also saw: Target Milestone: mozilla29 I'm not putting pressure on, keep up the good work. Maybe the fix got disabled for a reason?
Bugzilla can be hard to decode. Target milestone is the release that the check was first checked into, in this case Firefox 29 was nightly. The "Tracking Flags:" section status-firefox# shows when/if a fix was uplifted. In this case it shows that it was uplifted to Firefox 27 and verified to work.
I don't think this needs docs. It was a couple release regression. Users should just update to a current version from the Play Store.
I'll add this to https://developer.mozilla.org/en-US/Firefox/Releases/25/Site_Compatibility for the record, along with other regressions.
