I have tried repeatedly to wean her off FB and onto better alternatives such as Twitter or Diaspora*, but she still insists on using it. The thing is, it will (very often) start responding strangely to keyboard input, or not responding at all to the keyboard. I have tried everything I can think of to resolve this problem, but it still persists.
I've tried:
* Ensuring it has the latest Firefox browser installed
* Disabling all add-ons for the Firefox browser
* Using a different web browser entirely
* Using an external USB keyboard
Every other website works fine, in different browser tabs, it only seems to affect Facebook. It happens when there's only one tab open in the browser as well as with multiple tabs. We're running Lubuntu v14.04 LTS (Trusty Tahr) as the OS and there doesn't seem to be any other problem with the computer, just this. It is practically the only thing my wife ever does with that netbook, and it seems strange that it is the only thing that is causing a problem.
I've also tried suggesting that she compose her posts / messages in Leafpad (the default text editor in Lubuntu) and copy/paste them into FB. This works as long as she doesn't try to use the keyboard to paste. She has to use the touchpad, right-click/paste. However, messages are committed using the [ENTER] key only in the instant chat dialog, so this workaround fails at that point.
Even this doesn't convince her to stop using FB. She naturally assumes that the problem is Firefox, or Lubuntu, or Linux, and we should all just go back to using WindBlows. I'm certain that this is not a Linux issue, it is a Facebook issue. I just don't know how to prove it, and, if possible, to fix it. I mean, c'mon, how am I supposed to fix Facebook, amirite? ;-)
Any suggestions of what might be causing this, how to resolve it, or at least how to reduce its impact, would be really appreciated.
