I am having problems with Adobe Flash in Ubuntu, what are my options?
As you have identified - the best solution is usually to follow this Q&A to install flash. It does work for the vast majority of users.
Flash-Aid was discontinued by it's author and is unknown if it will be back, the following are kept only for historical reasons.
As an alternative, one of the best tools I have found that allows you to configure Flash correctly during installation is the Flash-Aid addon - use the author's site or search on the Firefox addon-manager for Flash-Aid
This will remove any remnants of of Flash installation and install flash directly from the Adobe Website. During the wizard installation you have a few configuration options that you can try to resolve flash-player issues.
Close & Restart Firefox / reboot for the change to take effect.
There are 2 options.
Enable the HTML5 player
For Youtube this can be done by loggin in, going to http://www.youtube.com/html5 and enabling it there. You can also just add
Whether your browser and the version you are using will support the HTML5 playback of a video on a site that provides such an option (like YouTube or VKontakte) will depend on the codec chosen by the site owners. For example, YouTube and VKontakte (a Facebook clone popuar in Russia) use different codecs for their HTML5 videos, which means that in Ubuntu 12.04 HTML5 video playback at VK.com works in Chromium, but not in Firefox (and in future, these browsers might swap their roles).
Install the Flash Aid Firefox plugin
I don't know for sure if this will work for you as well, but it worked for me.

For Firefox Flash, first try this:
when having issues after an automatic update.
This leaves one with Adobe Flash plugin version 11.2.???.??? in Firefox as Adobe no longer releases any higher flash versions for Linux.
For adding Google Chrome Pepper Flash plugin to Chromium:
The latest and greatest Adobe Flash version for Chrome (version 12.0 at the time of writing) is installed in Chromium.
This solution can also be scripted for easy installation on multiple machines:
Check your Flash version
This can be done on Adobe's site.
Try installing Flash by entering the following command in the Terminal
I am running Ubuntu 12.04 64-bit with an Nvidia GeForce 8400 GS.
I have been having the same issue ever since I corrected another Flash issue on my system related to Nvidia GPUs -- see Flash video appears blue on this forum. Following the workaround posted at the previous link stopped the unwanted behavior of all Flash video being tinted blue, but ended up causing the Flash plugin to crash nearly every time I attempted to watch a video online.
The solution for me was to look back at /etc/adobe/mms.cfg and remove everything but one line, which should read:
This idea and others are discussed on ubuntuforums, and many other places. Please try changing your mms.cfg (or creating it, if it does not already exist) and post back with your results. Good luck!
As for the HTML5 video playback option available at some sites:
First, not all sites provide HTML5 videos as an alternative to Flash (hopefully, there will be more).
And second, whether your browser and the version you are using will support the HTML5 playback of a video on a site that provides such an option (like YouTube or VKontakte) will depend on the codec chosen by the site owners. For example, YouTube and VKontakte (a Facebook clone popuar in Russia) use different codecs for their HTML5 videos, which means that in Ubuntu 12.04 HTML5 video playback at VK.com works in Chromium, but not in Firefox (and in future, these browsers might swap their roles).
And third, some videos might appear to not have the HTML5 option on YouTube. (For example: https://www.youtube.com/watch?v=3SacL219sic&html5=True.) But thanks to the answer by Klementine, there is a trick useful for getting at HTML5 playback in these cases -- use the "emdedded" variant. (For my sample video: https://www.youtube.com/embed/3SacL219sic.) And it works!
First, you need to go to http://get.adobe.com/flashplayer/ Then, select "APT for Ubuntu 10.04+." A window should pop up prompting you to select a program to use the apt link. You need to direct it to /usr/share/software-center/software-center. This file should be a python script. When it opens the software center, enable the source it tells you to. Then, once it is done, hit the install button. You may need to restart firefox for it to work, but that's how I did it, and it worked for me!
Hope this helps! -Michael
Here is what you need to do: (Im assuming you have flash 11 and firefox 14.0.1):
