I know that other, multiple questions have been posted on this, but I'm fairly certain I've applied most, if not all, of the suggested solutions, and I'm no closer to resolving this issue.
I am running Ubuntu 12.04 (Black Opal, 32-bit system, Firefox web browser), and I cannot use any website that provides flash video (e.g., YouTube). The page loads, but the typical black box with the "play" icon does not load...that area is completely white/blank. This is true of all other Flash sites.
I made sure I have the
ubuntu-restricted-extras package installed, and I even tried installing the
flashplugin-installer ... in fact, according to Synaptic Package Manager, I have that AND
flashplugin-downloader installed. Interestingly, I also have
adobe-flashplugin version 126.96.36.1990, which would seem to be correct (I know that support for Flash in Linux ended with 11.2) and both
-kde (whatever those are). Also, it appears that none of the previous Firefox
helper-extensions for flash in Linux are available any longer. I have no idea where to go from here, and being able to see flash websites is occasionally a necessity for me.
As an interesting related note: Google Chrome/Chromium (I can't remember which) was installed as part of my Ubuntu system install, and I seem to remember it working...until I installed the
flashplugin-installer to try and fix my problems with flash...now, Chrome doesn't even load! Double-clicking on the icon produces no response. Looking in the system monitor, I can see instances of Google Chrome are invoked when I double-click the icon, but there is no visible effect (no browser window, etc.)
Running Google Chrome from terminal shows:
[0428/183027:ERROR:nacl_helper_linux.cc(236)] NaCl helper process running without a sandbox! Most likely you need to configure your SUID sandbox correctly.
At the same time, I got a popup window that told me
System Problem has been detected (or something to that effect) and asked if I wanted to report it, etc, etc.
What did I do wrong, or what am I missing? Thanks in advance!
