Shareaholic Eliminates the Confusion from the Firefox Plug-In Error

Whenever you try to install a Firefox plug-in you usually get a warning stating “Firefox has prevented this site from asking you to install software on your computer”. If you actually read this, which most people do not, you then notice two options in the upper right hand corner of your browser window, as below.

What you are actually suppose to do is not really clear because the implications to a non-techie are hard to understand. (We, as techies, understand that Firefox has not been instructed that this site is “legit” and needs permission to install the plug-in, that we have to create an exception to allow it to be installed.) The options may seem easy since there are only two to choose from, but since most people don’t understand why they need to edit the options, they simply may not and instead click the X. The problem being that the necessary steps are unclear.

Shareaholic.com has bent around this issue as to make installing their plug-in completely pain free by creating a mini step-by-step how-to. See below:

Yes. There is more to read, but less to understand. It’s just 4 easy to follow steps. Fantastic! I love this!

What is Shareaholic?

Oh, I should mention, since you may be wondering, Shareaholic is also a really useful plug-in that makes submitting articles and bookmarks to your favorite social news and bookmarking sites pain free.

Shareaholic makes it easy for you to submit the web page you’re viewing to digg, del.icio.us, facebook, google bookmarks, magnolia, reddit, stumbleupon and twitter. If you prefer, you can also e-mail the web page to a friend.

Developers should take note as to what they have done, you don’t have to put up with lousy errors. You can easily find ways to remove their heuristic nature to your benefit.

Yep, The PDF Browser

I’m a PDF junky… Whenever I want to save a webpage I often print out a PDF, but browsing through them all is a hassle since they are often so visual. Yep does for PDFs what iTunes does for Music.

Upload a File, Get a Random One in Return

Pretty fun idea… File-Swap.com has you upload a file to their system’s queue and then sends you another users file to you.
