Flash player 11.9.900.170 for portable browsers (32 and 64 bits)

Flash 11 is outdated, you should rather get Flash 12 there (well, except for Linux where the latest version is 11.2.x and still maintained at the moment)

Since it seems version 11.9.900.170 is still somehow in high demand, I just added a new mirror here.

An important warning to Tor (would-be) users: if you choose to add the Flash plugin to TorBrowser (or whatever browser you use with Tor), this will most likely BREAK the anonymity. Flash tends to connect using any connection it can get, so it’s able to leak your IP to any site that really wants to get it.

Adobe just released a new version of their Flash Player: version 11 final aka (now updated to 11.9.900.170). The main new feature is that it finally has a 64 bits version! There’s also Stage 3D, which allows 3D GPU rendering, finally graphic intensive Flash games will be fast ^^. I’m not sure of what was subsequently added in versions 11.1, 11.2 and 11.3. I suppose versions 11.3.300.262 and .265 fix the chaos introduced in 11.3.300.257 with all the crashes in plugin-based browsers (at least, with Opera and Fx). This paragraph is now quite oudated… can’t wait for version 12 so that I can finally start a brand new Flash post from scratch…

To use that Flash portable, unpack it into the plugin folder for your browser, that is (paths are relative paths, relative to the portable browser’s root directory):

  • Firefox Portable: Data/plugins + set plugins.load_appdir_plugins to true in about:config
  • Opera USB: program/plugins
  • Iron or Chrome Portable: Iron/plugins

Note that Flashplayer.xpt is useless, it’s only included because it’s tiny and some people do look for it.

Here is the zip containing NPSWF32.dll (actually now named NPSWF32_11.9.900.170.dll) and flashplayer.xpt, and NPSWF64_11.9.900.170.dll, and also the new FlashPlayerPlugin_11.9.900.170.exe executable, which as far as I understood is related to Flash getting executed within a sandbox now (for some reason this executable is only provided with the 32 bits version though). You can choose your preferred download host between Megaupload and Filesonic, however note that the files hosted on FileSonic vanish after 30 days without a download, so usually only the latest versions (latest stable + latest preview if newer than stable) remain online there. Megaupload on the other hand should have all history of my uploads. It’s now on MediaFire and, which I believe don’t delete old files (at least MediaFire doesn’t), so apart from the oldest versions lost in the Megaupload takedown, the more recent ones should be all there.

For developers, here is also the debug version 11.7.700.202.

Older versions

If you’re interested in even older versions, here are (NB: due to Megaupload’s closure, almost all of them are offline now :():

Bonus: megaupload and filesonic directories MediaFire directory with all my Flash Portable uploads (since the day MU was shutdown and I lost most of my previous versions…). Note that the MegaUpload one also contains a few other portable things, while the FileSonic one is regularly purged of files not downloaded within the last 30 days (so usually it contains only a few most recent versions):
(NB: those are here just for historical purpose, MU was taken down by the FBI and FS purges the files so often that the folder is empty…)

NB: in Windows 7, after installation, Flash can be found in C:\Windows\SysWOW64\Macromed for the 32 bits version and C:\Windows\System32\Macromed for the 64 bits version.

    Not sure what your problem is… the paths are indicated at the end of the post, and anyway you can just search for sth like “NPSWF” I guess, there shouldn’t be too many matching files…

    Any chance hosting the file somewhere else ? Media fire and other sharing sites are blocked at work. Thanks!

  3. patheticcockroach says

    If you check out the “backup mirror”, you’ll notice it’s hosted on this very site 😉

    Some of the older versions are there too, but I don’t link to them because I’m never sure how long I’ll keep them before deleting them. You can get them via some trivial URL manipulations though.

  4. THKS says

    Got it 🙂

    11.3.300.257 is now available – please post, thanks

  6. patheticcockroach says

    Thanks for the notification. Links updated.

  7. Superbest says

    I am trying to install this on the TorBrowser form the Tor bundle. I extracted all the files into the plugins directory, but sites still tell me to install flash, and I can’t see anything under Plugins in the browser.

    Any ideas?

  8. patheticcockroach says

    Tor Browser disables all plugins because they can (and probably will) leak your real IP. I just had a quick look and it seems that you need to go to the Torbutton preferences dialog (extensions -> Torbutton -> Options), then to the security settings tab, then uncheck “disable plugins during Tor usage”.
    But again, if you do that, say bye bye to the “I’m anonymous” part of Tor Browser.

    11.3.300.257 is not working for me – I installed it like usual, but flash isn’t working – it works fine on my non-portable browsers.. could you put up the backup mirror for the previous version again? I should have saved the old files. I can’t access mediafire. Thanks

  10. patheticcockroach says

    The old file is there:
    Weird that it doesn’t work, though. Anyone else having the same problem?

  11. Anonymous says

    Well now the old version isn’t working either, so I must have a bigger problem going on. Thanks though

    I see information about Firefox 13 no longer supporting Windows 2000. I wonder if the new Adobe Flash has similarly dropped Windows 2000.

  13. patheticcockroach says

    Well, if you check out the system requirements for Flash 11 (, Windows 2000 isn’t listed indeed… But it looks like it applies to all 11.x versions, so if 11.2 worked, maybe 11.3 works as well.

  14. Anonymous says

    I found that the file from here is still the old version of, so it looks like they have included the same version and not the newer version of the flash player.

  15. Anonymous says

    Thanks DD – maybe to be safe I should just drop back to which appears to be the last Flash release that officially supported Windows 2000. I understand you no longer have it portable on your website, but is there any way you can make it portable again for us Windows 2000 folk? I downloaded the full version and tried to extract the .EXE file, but there is nothing recognizable inside..

    Actually I found an copy of which I saved from your site from 2011, so I’ll give that one a shot next time I am on the Windows 2000 computer. Thanks

  18. patheticcockroach says

    They allow links, they just wait in the queue 😉
    Without the FBI messing with MU I’d still have the links to 10.x portable 🙁 If I find the time I’ll repackage it. last version supported you say ?

  19. George says

    hi, the new mediafire file requires a password. may i please know what the password is? thanks! 🙂

  20. patheticcockroach says

    Hmm… there’s no password on the MediaFire file… Where do you need a password to begin with, to download or to unzip?

  21. patheticcockroach says

    I just realized, I have Flash on MediaFire there

  22. Kelly says

    The previous version works fine on Firefox 13 but the new version doesn’t. Browser just hangs. Hope you can help me out.

  23. patheticcockroach says

    I just tested that on another computer which I hadn’t upgraded yet, and yes it seems that manually copy/pasting the new DLL just freezes the browser (Fx 16 here). I tried uninstalling the existing Flash version just in case it was a conflict : same result… The file isn’t corrupted, checksums are similar :
    # MD5 checksums generated by MD5summer (
    # Generated 2012-06-11 15:25:54

    c25b91466d8c383299e9e2023f8f7a5a *NPSWF32_11_3_300_257 (2).dll
    c25b91466d8c383299e9e2023f8f7a5a *NPSWF32_11_3_300_257.dll

    … so, putting back the link at the main spot… I hope it’s a temporary issue that will eventually go away….

  24. patheticcockroach says

    It’s quite possible. The only strange thing is that on both computers where I tested it, Flash 11.3 works without any problem when I install it using the installer: only the “portable” Flash crashes.

  25. Anonymous says

    Firefox 13.0.1 is out now which supposedly fixes the flash bug.. it looks like the Portable version has already been updated.. anyone have better luck? I was able to downgrade to and it works fine on Windows 2000 with Firefox 12 now -thanks!

  26. Bergamot says

    I’m running windows 7, and the new flash player (11.3) is hanging. According to the adobe support forums, the new flash version uses a separate executable as a sandbox. Could you also include this executable in the zip package, so that it can be found by the browser plugin? Thanks!

  27. patheticcockroach says

    Thanks a lot for the information, I updated the zip on the backup mirror (, will update the one on MF later. Note that I only found an executable for the 32 bits version…

  28. Anonymous says

    Thanks for pointing me in the right direction! I got Flash plugin working only when the files FlashPlayerPlugin_11_3_300_257.exe and NPSWF32_11_3_300_257.dll are in the FirefoxPortable\App\Firefox\plugins folder of FirefoxPorable 13.0.1.

  29. Anonymous says

    I still can’t get it to work after trying everything outlined above in the comments. Anybody else had any luck?

  30. patheticcockroach says

    Which browser ? And also, which problem: the crash problem or just Flash doesn’t seem to be “installed” ?

  31. patheticcockroach says

    I see Flash 11.3.300.262 is out, will upload it when the offline installer is available:
    Edit: posted.

  32. HansWurst says

    can you give me an eta when = Adobe Flash Player 11.3.300.265 will be available here ?
    FF portable (14.0.1) still freezes with 11.3.300.262


  33. patheticcockroach says

    I don’t monitor the updates, so thanks for letting me know 🙂 I hope to be able to upload it soon, or at worst this evening.

  34. patheticcockroach says

    Just realized I didn’t package the right executable in version 262… Anyway here is version 11.3.300.265:

    And as a bonus I signed the file:

    Version: GnuPG v2.0.17 (MingW32)

  35. Kelly says

    Thanks for your hard work.

  36. HansWurst says

    Thanks for the update. Unfortunately FF still freezes even with the new version.
    Am i the only one with that problem or can anyone confirm this too ?

  37. patheticcockroach says

    I have issues from time to time (random crashes every few days), but it usually works okay otherwise. Using Fx 17 (nightly) or sometimes 15 (beta).

  38. HansWurst says

    Iam using version 14.0.1 (You are currently on the “release” update channel).
    With Flash i have no problem at all. With the latest version i couldnt even load youtube without the plugin container freezing. When i kill the plugin container everything loads fine, but after a few seconds it freezes again. 🙁

  39. patheticcockroach says

    I’d say maybe try beta (it’s called beta but I’ve actually never had original bugs with it, unlike nightly)… maybe also update the graphics drivers if they are really outdated… Otherwise I don’t know :/

    Its working again here with the new version and FF14.
    Thanks, you are great!

  41. patheticcockroach says

  42. HansWurst says
