What are the system fonts of Firefox OS? - firefox-os

Fira Sans seems to be the default font, but I'm wondering what other fonts are on the device that can be used by apps via CSS.

This file describes the fonts that are installed in Firefox OS: https://github.com/mozilla-b2g/moztt/blob/master/fonts.mk. This is for the master branch. Check the other branches in the git repository to find out about fonts available in a specific Firefox OS version.

Install custom plugin on Google Ghrome Ubuntu 14.04

I've got a problem while trying to install rutoken plugin for Google Chrome v. 40.0.2214.115 (64-bit) on Ubuntu 14.04.
That's what I try:
Download plugin from http://www.rutoken.ru/support/download/rutoken-plugin/ and unpack files, so I had librtpkcs11ecp.so, npCryptoPlugin.so files.
Create a directory for plugins, in the Google Chrome's installation directory.
sudo mkdir /opt/google/chrome/plugins
Copy *.so files to the plugins directory.
Then I've restarted Chrome:
google-chrome -–enable-plugins
The problem is that when I run chrome://plugins/ there is no such plugin in a list.
It seems Java JRE is not more working on Chrome

NPAPI support by Chrome
The Java plug-in for web browsers relies on the cross platform plugin architecture NPAPI, which has long been, and currently is, supported by all major web browsers. Google announced in September 2013 plans to remove NPAPI support from Chrome by "the end of 2014", thus effectively dropping support for Silverlight, Java, Facebook Video and other similar NPAPI based plugins. Recently, Google has revised their plans and now state that they plan to completely remove NPAPI by late 2015. As it is unclear if these dates will be further extended or not, we strongly recommend Java users consider alternatives to Chrome as soon as possible. Instead, we recommend Firefox, Internet Explorer and Safari as longer-term options.
I installed plugin updated but I face issue at testing time plugin not work properly in Chrome using link http://java.com/en/download/installed8.jsp?detect=jre If you got message "This plug-in is not supported" then follow following steps:
In your URL bar, enter:
chrome://flags/#enable-npapi
Click the Enable link for the Enable NPAPI configuration option.
Click the Relaunch button that now appears at the bottom of the
configuration page.
and test it again using http://java.com/en/download/installed8.jsp?detect=jre link.

infinality fonts and Windows fonts emulation

I want to emulate Windows 7 fonts on my Ubuntu 13.10 system. I installed infinality and tried a couple of themes via infctl.sh (Win7 and OSX2 ones). Alas, none of them was fully suitable: OSX2 theme needs to be darker and Win7 theme needs to be thicker.
In tried to modify the filter matrix via infinality-settings.sh. It writes the proper (modified) values to the environment variables, but nothing happens to my rendered fonts. I restarted my machine several times, but it does not help.
Cannot you tell me the proper way to modify my filter settings?
P.S. My antialiasing settings are here.
P.P.S. My printenv dumps are here.
Heh, the reason was rather simple: I had my FreeType installed not from no1wantdthisname PPA, but from the default Ubuntu repository. So, the Freetype itself was not patched, only fontconfig-infinality was installed.

Various versions of chrome on linux

I'm looking for the way to conduct cross-browser compatibility test on my ubuntu. Firefox and opera don't cause problems, but I didn't find any guide how to install older versions of chrome. Do you know how to check my code in this browser on my computer?
You can take screenshots in different versions in Browserstack. Also you can browse there using different browsers, but you will need to pay for that.
In general, there is no need to test compatibility against anything but the latest version of Chrome, since Chrome updates itself automatically. Just expect that anyone using Chrome to view your site will have the latest version.

css 3d not working on linux chrome

Hey i was wondering if anyone else has had problems with css 3d running on chrome on linux (specifically fedora 17). Chrome in Windows seems to handle everything fine but for some reason it won't work in Fedora. I get errors saying that my browser doesn't support 3d transforms.
Chrome/ium is probably the most popular option, so if the version you tried wasn't working, you may want to update to the very latest -- something like the Chromium Daily Builds. If even that is too buggy to work with, you might want to try a different Webkit browser for Linux.
Midori and Epiphany are two decent options. As an added bonus, I think both of these browsers will use the version of Webkit that you have installed on your system (unlike Chrome, which comes with its own version of Webkit). That means that you should be able to build Webkit from the latest nightly source release, and Midori or Epiphany will automatically use that version.
WebKit Nightly Builds
I hope that this help you.

Playing wav files in Firefox on Red Hat

We have a JavaScript construct that will play .wav files within Firefox on Windows and MacOSX, but it does not work for Red Hat Linux. What extension do I need?
Firefox 3.1 will support Firefox 3.5, supports the <audio> tag, a standard tag to deal with sound. If you use that, you'll need no extensions.
Unfortunately, that will only work with the latest browsers (Firefox 3, for example, is the latest stable version and yet does not support this tag. You may have trouble making it work with Internet Explorer too).
Try mplayerplug-in, which is available in rpmforge and rpmfusion. It requires mplayer to be installed (obviously) and AFAIK it can play virtually anything.
Have you tried Moonlight? I don't think the Media Codec pack was available when you first asked but it's avilable now ;-)
