Missing images on The Guardian
Posted by: foliator

Can anyone tell me why most of the images on The Guardian's home page - https://www.theguardian.com/international - are missing in K-Meleon? The images always show up inside the individual articles; only the home page is affected. Other browsers display all the images on the home page.

I was thinking there might be a setting in about:config that would correct this, but I don't know what to look for there.

I have no clue either, but I found what may be the culprit here.

There is a http connection to this site and a json report about something being blocked.
https://beacon.gu-web.net/csp-report

{
	"csp-report" : {
	"document-uri" : "https://www.theguardian.com/international";,
	"referrer" : "",
	"blocked-uri" : "http://media.guim.co.uk/5b4d31c5f9083171a0869dc0a78dec04b12e46e5/275_70_3494_2096/master/3494.jpg";,
	"violated-directive" : "img-src https://*:* data://*:* blob://*:*"
}

}

EDIT: Oh, I forgot to say that CSP stands for content security policy:
https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP

Editing CSP preferences, does nothing for me confused smiley

Why others bypass is beyond my knowledge, but as you use K-meleon 75 and Firefox 31.7 loads them fine, might be fixed or at 75.1 or 76.

I just opened that link to the URL being blocked, and got this:

"This XML file does not appear to have any style information associated with it. The document tree is shown below."

(What follows is a lot of unreadable stuff enclosed in <error> tags.)

So it would appear that other browsers, including Pale Moon (which I no longer use) and SRWare Iron, somehow manage to ignore the error.

I did see the domain name for that blocked URL go by briefly on my status bar while loading the page.

By the way, when viewing The Guardian's videos in Pale Moon, some of those background URLs never stopped loading, which slowed down the video streams to a crawl. But then, Pale Moon's video rendering was choppy to begin with, which is why I stopped using it altogether. There is no such problem in either KM or Iron.

Works with K-Meleon 76.

Interesting! I tried 76 RC a while back before I became aware of The Guardian, so I never visited it back then. However, I had other unrelated problems with that version, and reverted to 75, which works very well on most sites. Maybe I'll give 76 another try.

OK, I tried 76 RC again. What a trade-off! Yes, The Guardian's images load properly, but in exchange for two other issues:

1) about:preferences doesn't work right (a known issue). I can't even bring up the applications list, and it doesn't even show up in the file handling tab of K-Meleon's settings dialogue.

2) YouTube videos are now choppy, whereas they're quite smooth in 75. This I was unaware of, because I hadn't tried YouTube in 76 RC. It's the same behavior I noticed in the latest Pale Moon (based on Firefox 45.9). In KM's case it's probably due to the more recent Gecko version (38 rather than 31).

Those two issues are more critical than the missing images in The Guardian, so I guess I'll stick with KM 75.

Back to the stable

But are you using 75.1?

As I told above, in Firefox 31.7, or Gecko 31.7, as you prefer, it works. K-meleon 75.1 is based on Gecko 31.8, so if something got fixed then, should work in 75.1. Otherwise there might be some pref, as you pointed in the initial post.

It might be so obvious to tell this, but, by your forum signature, I know you are running 75, but not which one.

It doesn't work for me with 75.1.
As for prefs, I have set them identic in both 75.1 and 76.
Whatever, maybe I'm missing something.
Videos on YouTube are playing nice for me in 76 as they do in 75.1.

I'm using 75.0. I'll have to edit that signature to make it clearer. I didn't bother to upgrade to 75.1, because I had already customized 75.0 to my liking through some macros I found on this forum, a few of which I modified slightly.

I guess it depends on the hardware and OS in use. I've noticed that videos other than those from YouTube play smoothly in 76. YouTube is getting to be a pain in the butt. They keep making changes to their software, often causing problems for users.

p.1 is fixed in KM 76 Pro build. Try it.

p.2 I have nothing to say about. I have the mostly same experience with Youtube videos in both browsers.

Yes, I just tried it and about:preferences is fine there, but I have a major problem using Gecko 38:

Maybe it has something to do with my system, but any of the Gecko versions later than 31 render all videos poorly, which applies also to streaming webcams. I've encountered that in Firefox 43, Pale Moon 27.3 (reports Gecko 45.9), KM 76 RC and KM 76 Pro (both of which use Gecko 38). I've seen lots of complaints online about Firefox's choppy video rendering, and the advice is usually "disable hardware acceleration". That makes absolutely no difference on my machine.

Regarding video playback, by the way, TheWorld 7 no longer plays any YouTube videos, at least on my end, although non-YouTube streams play just fine.

So the only two browsers that consistently play video streams properly here are KM 75.0 and SRWare Iron 51 (a Chrome clone); in fact, KM 75.0 plays them more smoothly than Iron. Vivaldi is yet another Chrome-based browser that I tried a while back, but videos there didn't render poorly, because they wouldn't even start playing!

I don't know if this would help, but just FYI:

you can watch youtube videos on the http://jojoplay.com - they are shown there without ads (it seems so) and maybe they could be played smoother than on youtube (or maybe not).

Try.

(just search for video like on youtube or take known YT-url and change
https://www.youtube.com/watch?v=somealphanumerichere
to
http://www.jojoplay.com/watch/somealphanumerichere
)

Thanks, rodocop. They come out the same on that site, so it's not the YouTube site, but the browser's video rendering that's at fault, which is probably why it affects not only YouTube's videos, but all video streams, such as those streaming webcams and even direct links to MP4 videos. I use the HTML5 player for those MP4s, otherwise the browser has to download them to a temporary file before it can play them in my local media player, and that can take a long time.

My video card or my internet connection may be part of the rendering problem, too, but there's little I can do about that. Anyway, if it's a very important video -- and few of them are grinning smiley -- I can simply download it and watch it offline in my media player. That will play it the way it's supposed to be played.

There are (almost) hundreds of prefs for media playing in gecko, so I strongly suspect such video probs are often just caused by different Default settings.
Perhaps flash settings are different, or some others ("media" in about:config)
pref("dom.ipc.plugins.enabled.npswf32.dll", true);



PS Offtopic note to all, just speaking of plugins:
Even I can remember that FF dropped support for Netscape plugins completely (except flash) in FF52 (KM78 :coolsmiling smiley. Well possible it was already mentioned too, not sure, just in case if not: so far that's just a pref. Of course, being Mozilla, a hidden pref. And top-secret, it doesn't even show up in about:config it seems, users have to unhide it themselves

@foliator: no idea if it helps, but read somewhere that choppy videos can sometimes be related to constant session saving. They recommend to TEST with 5 minutes, but for normal session purposes too long of course
pref("browser.sessionstore.interval", 300000 );

Gecko has more than this one hidden pref.
It could be even worse like it is in other browsers. You don't have any hidden pref. The setting is hardcoded.

In FirefoxESR 52.2.1 "plugin.load_flash_only" is still visible and set to false by default.

Very disappointing !!
Jojoplay does allot viewing though, so not all is offline now.

How does one verify this deeply hidden pref and/or change it then, anyone ??

Thanks.

Same as all prefs, go to page about:config, either type into urlbar or using menu (Edit>Configuration>Browser Configuration)
If the pref doesn't show up, right-click and create it (type BOOL)
