Firefox Apps on Desktops!

The Firefox browser has always thrived as the underdog; the "alternative" browser of choice. It's this sort of identity, along with it's historically strong security record and OpenSource nature, that had propelled it and its predecessor, "mozilla browser", to near 50-percent usage share by some counts. More recently, however, with the browser-market saturation expanded by the additions of Apple's Safari and Google's Chrome browser, Firefox's usage-share has been experiencing a downward trend; even as the newer additions to the browser-market have seen exponential user growth, i.e. Chrome!

Firefox--Multiple plugins Directories

There are a number of legitimate reasons why one would have multiple versions of Firefox installed on one system.  While, it's generally ill-advised to have multiple versions of the same package/software installed--as it could create resource conflicts and system hangups--recent versions of Firefox have become more stable in this type of scenario.  The Developer Edition of Firefox, for example, has an option under Preferences that specifies whether or not to "allow Firefox Developer Edition and Firefox to run at the same time" through the use of different Profiles.

While this is a nice functionality, there are still some issues with the system-wide Library path and the local ".mozilla" directory in the user's home directory.  There's still an issue with installed plugins, which are in the system-wide directory "/usr/lib64/mozilla/plugins/" on a 64-bit system, not available in the second installed firefox package unless the user creates links t…

Troubleshoot JavaScript Functionality--Firefox Browser and DD-WRT Network Router

HTML5 is here! On October 28th, 2014 the HTML Working Grouppublished HTML5 as W3C Recommendation. This specification defines the fifth major revision of the Hypertext Markup Language (HTML), the format used to build Web pages and applications, and the cornerstone of the Open Web Platform.

When the talk of HTML5 comes up generally it's understood that, for the most part, CSS3 and JavaScript are an intricate part of the "whole". Extended features such as responsive design among other things are nothing without all three languages. JavaScript in particular uproots the "operating system" and unshackles users from the confinement of locally-run software with seemingly boundless potential.

Well, if that wasn't a loaded statement then you still have faith that I know what I'm talking about. Regardless, this post is mainly meant to help troubleshoot the possible causes of a half-assed web-experience followed by constant, nagging banners suggesting that you…
