Just an update for those of you who took the time to offer your resources, time, patience, and good luck wishes:
Sometimes we just need to get away from the computer, forget about what we "think" we did in our lives to warrant such a tumultuous unforgiving computer polter4geist moment....and just walk away.
And today...the stress, angst, hair pulling (oops, I was bald before this experience)....seemed unimportant. Why? Because I have been saved!
Not like a biblical awakening, but more likened to an accidental discovery. The stars aligned, my logitech wireless keyboard lights began flashing, and I mentally prepared myself for what I thought was to become a "Bill and Ted's Excellent Adventure ! Okay, Okay...perhaps a bit melodramatic there , but it really was a light-bulb, teachable moment for me!!!!
The moral of that moment: just keep tinkering, tweaking, and try your hardest to connect the cyberdots, but don't give up. When all the expert solutions don't seem to get the job done....finding backdoors can sometimes be your only hope. YEAH!!
The solution came when I realized that although the plugin that I required to run my java applet is exiled somewhere into oblivion, no repository, etc...I had it on my laptop, but couldn't for the life of me, figure out how to Houdinni it through my network and have it appear as an add-on in my mozilla Firefox plugin list on my desktop.
SYNCING became my light bulb moment.
Each device saves its own preferences or (profile) on each individual device. All I needed to do was change the name of the device on the SYNC page to that of the SYNC name of my laptop ( that had the awol Java platform plugin I so desperately sought after) had. Then I saved that new device name on my desktop, hit the sync button.....and whalla! My living nightmare was a thing of the past! My desktop now had All of the same add-ons that were on my older laptop computer.
I'm sure for most of you out here...my light bulb moment will seem silly, but I truly tried every recommendation to no avail. Hopefully, my sharing will bring others to the same kinds of discoveries as they inch closer to their "ah, HA!" moments! Thanks all to those of you who helped inspire me with the courage to keep plugging along PUN Intended!
