I have a question about Mint17.1 Rebecca.

For some reasson,I can't play anything flashbased, while I have the latest upgrades in Firefox and Opera. These upgrades are up to date to Adobe Flash Player 11.3.300 but none the less, they dont work.

I tried to play a windows firefox version in Wine over Playonlinux, but these seem to crash constantly and dont support the Flash either. What can I do about this problem, that only recently started? 1 month or two earlier, this was no issue.

I tried down;loading from the adobe site aswel.

flash works pretty well on ubuntu 14.04 and so should on Mint. try also your luck with chromium-browser.

alternatives: there seems to be an opensource flash player but can't recall the name.

I'm confused here, I don't know whether the adobe site is telling me lies or you've read the Flash Player version wrong, but Adobe says that the latest is 11.2.202.406.
When you say that you can't play anything what do you mean? Does nothing come up, does something come up but it's garbled or what exactly? How did you determine your Flash version?

Try an older Flash

or get the free equivalent Gnash

There's also FreshPlayer:

It uses Pepper as a Flash Player.
