Hi, wondering when running Ubuntu 14.04 with Flash on Firefox 39.0
Is there anything in particular to be worried about when running the 11.2.x Flash and not the 18.x Flash that is blocked by default?

Hello, is there a known issue with the language of Firefox on Ubuntu? It's in English although my system is localized to French
Has something changed in the way languages are dealt with Firefox? I also have the firefox-locale-fr package installed with no effect.
kbrosnan
Apteryx: ubuntu does their own repacking for language packs
i'm not sure if flash 11.2 is affected by the 0 dayy\
DrGrov: 11.2 should be blocked now that I have checked

DrGrov
kbrosnan: Okay, thank you. I will just keep activating it when I need it on YouTube and my country's web-based programs on TV
gschanuel
hello :)
awesomess3
soooo.....Firefox says my Adobe Flash plug-in is unsafe/unupdated yet I'm at the latest version...so...yah...hm...
b0at
because adobe hasn't fixed it yet
gschanuel
folks, I just noticed it today.. I did maybe two upgrades before noticing. Youtube with HTLM5 is showing only 360p quality. I have already done this before and it worked http://www.ghacks.net/2014/07/25/enable-mse-h2-64-support-youtube-firefox-right-now/
b0at
i guess
         

gschanuel
but now it just.. stoped working
I'm on firefox 39.0 on linux
b0at
gschanuel: as of a couple of months ago, it should all be enabled by default on linux and windows, at least
so version 36 or 37, and 39 is current (on stable channel)
so as long as firefox is new enough and all the gstreamer-1.0 packages are installed, it should be good
if you've been editing the mse prefs, you might try a new firefox profile just to see what the defaults are, and how it works
gschanuel
on https://www.youtube.com/html5 it is shown all available, but still youtube videos are limited to 360p
hu
actually..
just tested another video and it worked with 1080p..
but this one do not https://www.youtube.com/watch?v=8a5ID0x932I
b0at
hm, i get the same on windows, but chrome gets more resolution options. my guess is youtube is doing something wrong there.
since that's all their own code on the interface
gschanuel
well.. ok then
^^
b0at
(Action) usually plugs hi-res videos into mpv or smplayer or vlc anyway to get more flexibility and performance

The http 2.0 standard states the encryption is optional. However, firefox seems to only support http 2.0 with encryption. No options to enable plain text http 2.0 in about:config. I emailed a developer, and he stated that firefox will not support plain text http 2.0. Does anyone know of a webbrowser that will support plain text http 2.0.

When watching youtube with the html 5 player, sound works, but video doesn't.
b0at
wikipedia says chrome also will only support encrypted http2 (which is what i thought the point of spdy was, anyway): https://en.wikipedia.org/wiki/HTTP/2#Encryption">https://en.wikipedia.org/wiki/HTTP/2#Encryption
Somelauw
It does show previews in the scrollbar, but the actual video remains on the initial frame for me.
keith-man_
I need to use plain text http 2.
b0at
keith-man_: so the only browsers or browser engines with the manpower to do different would be apple with webkit, and they're slow on the draw, or microsoft with its rejuvinated IE engine, if windows is an option
unless libcurl is planning support... that's a possibility
styl1te
does anyone know how to make up-arrow and down-arrow do the defaults on Google's results page? they changed it recently to move a little triangle
b0at
opera supports http2. they sometimes do their own thing, so it might not use google's blink implementation.

Is there a way to prevent sites from hijacking mouse/keyboard input. For example, on most sites, I can drag and "throw" a link to open it (thanks to tab utilities) but on a couple sites like github.com it doesn't work, as if the site is overiding it some how (probably via javascript as it works with JS turned off.)
keith-man_
I just find it very frustrating that I can't enable it all. I don't see any options that will let me do that. I can understand it being disabled by default, but I leaving me no choice in the matter other than editing the source code is ridiculous.
Somelauw
I'm using firefox + linux + youtube + html5
styl1te
alanjf: sounds like we just asked the same question
alanjf
styl1te: Indeed. It's sites that overide/hiajck default actions and some shortcuts and that gets annoying.
keith-man_
So know one knows of any browsers that supports unencrypted http/2. Not even any forks?
         

alanjf
http/2 ??

Do I need MSE & H.264 Media Source Extensions MSE & WebM VP9 ?

hello, does fglrx (Radeon R9 285) supports WebGL acceleration in Firefox? It seems to be blacklisted by default.
And when I turn it on, I get a lot of flickering happening on some sites (e.g.: map.google.com)

hi #firefox
can anyone explain why I'm getting a flash blocked warning but when I go to the plugin check page for firefox it says everything is up to date?
https://blocklist.addons.mozilla.org/en-US/firefox/blocked/p948
https://www.mozilla.org/en-US/plugincheck/
Kiah
Because firefox blocks flash by default, now
kbrosnan
rachelfish: because flash has a active 0 day attack that is unpatched
rachelfish
how do we know it was a 0 day
what if the guy found it on the 7th day?
kbrosnan
0day is a specific term to mean a critical unpatched security flaw that in release software

I will try to reiterate my problem from earlier. Most youtube videos seem to work, but some will simply not start. If I try to skip ahead to force it to load, I get the error about adobe flash, and then one of the cores of my CPU will remain at 100% no matter what I do, until I kill (not close) firefox, manually. Also, I already had youtube set to use the html5 player
b0at
sometimes it helps to clear the cache with youtube's html5 player.
Kiah
How would I do that?
b0at
history -> clear recent history... or ctrl+shift+del, uncheck everything but "Cache", and set the time range at the top to "everything"
(i think that preserves the dom storage some sites use, which the options->advanced->network->clear now button may clear)
Kiah
That didn't do it
b0at
hm, ok
Kiah
Thank you though
kbrosnan
Kiah: if you have vp9 or webm enabled for mse video playback can be poor
Kiah: https://www.youtube.com/html5
Kiah
Yes, I do. I recently turned those on so that I could watch videos in HD. And the ones that work work great. There seems to just be a select portion of videos that simply don't work, and cause the CPU issue, even after closing them
Apteryx
Is WebGL supposed to be enabled by default using AMD R9 285 with proprietary drivers (Catalyst) on Ubuntu?
the OpenGL support is "basic" if I go to about:support
kbrosnan
Apteryx
kbrosnan: Thanks, I had seen this: For the FGLRX (proprietary ATI) driver, we whitelist the newer versions that implement OpenGL 3.0 or newer
So it should work since my Catalyst driver supports OpenGL 4.4
but it is somehow blacklisted, and if I force enable it, flickering happens on many pages... So does that mean that the Catalyst driver is still crap regarding WebGL? Or is the problem on Firefox's side?
Johne
how was flash blocked without an update? is there some plugin api that version checks?
b0at
there's a separate plugin block list
Johne
thats cool
was just curious how that was possible
i uninstalled flash from all my boxes today. time to put it to bed.
breee
why is firefox freezing all the time? No reaction to any input periodically, from a few seconds up
broke?
b0at
breee: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode#w_how-to-start-firefox-in-safe-mode
try that. if it works better, restart and try disabling extensions or plugins until you find the one or combination of them which cause the problem.
*restart again into regular mode
Apteryx
Is the sense of speed in Firefox highly CPU bound?
By sense of speed I mean the speed of which things get rendered, and smoothness of scrolling, etc.
On my job laptop (Windows) everything is so silk smooth in Firefox.
b0at
some of it is probably gpu or gpu-driver bound, with hardware acceleration built in
turned on, rather
Apteryx
On both my Linux laptop & desktop, Firefox is noticably slower at everything.
b0at: OK. Looks like Windows GPU drivers are a hell of a lot better than Linux ones (I already knew that, but this is a sad reminder)
b0at
i don't think that webgl as such is used for that, though. webgl is just a technique for accelerated drawing done by a web page. the browser itself can do more tricks, not being constrained to web-only stuff
yeah, that's probably the case
although it might be worth finding a way to benchmark the two systems in comparison, to see whether firefox is still performing sub-optimally
Apteryx
Next question, who is to blame for the broken hardware acceleration in Firefox on Linux when using the Catalyst driver (and a cutting edge Radeon card)?
Given that Chromium does a decent job using the same driver, I'd say Firefox?
