Test Drive Flash Player 10 Beta in Ubuntu

[update] Adobe has released a new beta, this version is no longer available. See Test Drive Adobe Flash Player 10 Beta 2 in Ubuntu for updated instructions.

Adobe has released the Flash Player 10 Beta simultaneously for Linux, Mac, and Windows. This version includes performance improvements, new 3D transformations, Adobe Pixel Bender filters, streaming video improvements, and new text layout capabilities.

Websites very likely won’t be taking advantage of these new features until the stable release is out, so Adobe has a page of demos you can try.

Two large complaints about Flash on Linux are fullscreen video and 64-bit support. Neither have been resolved in this release. Playback of fullscreen video (which causes low framerates and high CPU usage) seems to be only slightly improved. I have found that there is a general performance increase.

If you want to try Flash Player 10 you can download and install it yourself, but here are some terminal commands that you can copy and paste to get going quickly:

  1. Remove your existing Flash plugin, if you have one installed. This command will remove Flash 9 if you installed it from Ubuntu’s repository:

    sudo apt-get remove flashplugin-nonfree
  2. Download and extract the Flash Player 10 Beta to your home directory:

    wget -O - | tar xz -C ~
  3. The user plugins folder may not exist yet, try to create it but ignore any errors if the directory already exists:

    mkdir ~/.mozilla/plugins/
  4. Copy the Flash plugin the the Firefox plugins directory to install it:

    cp ~/install_flash_player_10_linux/ ~/.mozilla/plugins/
  5. Remove the directory that was downloaded (if you get a warning about deleting a write-protected file, press y and Enter to continue):

    rm -r ~/install_flash_player_10_linux

Restart Firefox to enable the new plugin.

And here’s how to uninstall it:

  1. Remove the new plugin:

    rm ~/.mozilla/plugins/
  2. Reinstall Flash 9 from the repositories (if you wish):

    sudo apt-get install flashplugin-nonfree

[update] I’ve been using the Flash 10 plugin for over a week now, and the only issue I’ve had is the occasional website that thinks my version of Flash is too old.

Pretty cool. I definitely want to give this a try, since Flash 9 has been giving me so much trouble on AMD64.

I started an “idea” on Ubuntu Brainstorm to create a deb package in the repositories for Flash 10 beta. Give it a vote here:


Supposedly, a deb exists for this. Or so their site says.

I guess 64bit people shouldn’t be trying this though, when flash was setup by ubuntu?

Use metacity instead of compiz and full screen videos work with no loss of framerate here. I hope it’s fixed so I can use compiz + flash soon.


I have it installed on both of my desktop/laptop and it works great. I am really glad the Adobe brought out a Linux versions with the other two.


Ubuntu Hardy Heron 64-bit users can install this following this post:

Darren, what you said is not true. Compiz-Fusion has nothing to do with Flash 910 full screen losing framerate. They are bugs within Flash for Linux because many people who *don’t* run Compiz get choppy full screen videos. This is because Adobe programmed Flash for Linux poorly. The fix is Adobe’s responsibility, but since it is proprietary, closed-source code (the very principal open source free software Ubuntu is trying to avoid) , no one can edit Flash in order to fix the problems.


The number one problem is that when you have DHTML menus that drop down into the region which a Flash video occupies, it falls “under” it, rather than over it as it does in Windows.

Slow full screen video performance can be solved by not using a shitty computer.


You’re extremely wrong on both counts.

There’s a toggle in the embed code to make Flash respect normal z-index layering, I don’t know it offhand, but look it up.

My computer has a GeForce 8800GT and a 2.2ghz dual core with 8 gigs of RAM. It can play Crysis at almost full settings, but it has trouble with fullscreen flash.

“Slow full screen video performance can be solved by not using a shitty computer.”

I couldn’t be ar*ed typing out my laptop’s (hi) specs, but your comment is total BS.


One problem I found with this version is that the new multiple file uploader in WordPess 2.5 no longer opens the file selection dialog.

I’m now wondering how can I get the flash player 9 back again…

Can you tell us?


@Martijin: These DEBs are old.
