Portable Adobe Flash Player

Ever wanted to carry a fully functional browser with Adobe Flash Player on your USB thumb drive or using Firefox Portable on non-admin accounts, but still have the Adobe Flash player which is obviously not installed on the system you’re about to use? Look no further, because here is the solution!

As of Firefox version 71 and up, Firefox doesn’t register plugins installed in Firefox folder anymore, meaning Portable Adobe Flash won’t work anymore in latest Firefox versions. Only way to still use Portable Adobe Flash with Firefox is to use ESR version, at least until ESR reaches version 71 too. Then it’ll be over. At which time, Adobe Flash will be officially dead too.

What you need is a portable browser like Firefox Portable ESR:

Unpack 7z archive to a desired location…

Download one of these two Adobe Flash plugins (if unsure, download both):
Adobe Flash Player Portable Plugin Download (32bit and 64bit)

Version available for download:
32.0.0.403

Open Firefox Portable folder and browse to the folder:
.\Data\plugins

Drop Adobe Flash plugin files (unpack the 7z archive first!) in it and restart it, if it’s running at the moment. Voila, you now have a fully portable Adobe Flash capable browser that can work even on non-admin user accounts (like Limited or Guest).

Test if Adobe Flash is working properly here (use to check which is the latest version):

Be aware that such stand-alone portable version of Adobe Flash DOES NOT auto update itself, so make sure you have the latest possible version! Luckily Firefox will warn you once plugin is too outdated. Gap between plugin update by Adobe and me updating the download on my page is usually less than 24 hours. If I forget to upload latest version in this timeframe, let me know and I’ll update it.

Disclaimer:
The binaries are NOT modified in any way! I have only unpacked them from the Adobe Flash installers so they can be used for portable apps. To be sure, check the files digital signature which has to be issued by the “Adobe Systems Incorporated”. If the signature is not there, broken or invalid, please delete these files immediately and notify me here!

  1. Hi all,

    For more recent versions of FF, there is something else that should be configured? I’m using the latest version of FF that is available on PA (v72.x), and despite I’ve followed the instructions, it seems that it’s not recognizing the plug-in.

    Thanks in advance, kind regards.

      1. Well, I have tried with both versions (x86, x64) to no avail. None of these packages is recognized on the Plugins section.

        According to “About” menu, the version downloaded from PA is “73.0 (64-bit)” (it was updated recently).

        As a workaround I’m using an old version of FF, and there it just work fine.

      2. Hi!

        Well, I made a quick test, I downloaded each version from current, 73.0, down to 70.0 and it seems that the last version where it worked was 70.0.1 (all running on x64).

        Starting from version 71.0 (released on 2019-12-05, according to PA) it doesn’t recognize the plugin… So, it’s safe to assume that they changed something on that version that it’s causing that the plugin isn’t recognized anymore.

      3. Apparently, Mozilla sacked support for loading plugins from app folders with Firefox 71 and above. Meaning Portable Adobe Flash is now essentially a dead project. Using outdated browser is a bad idea so using old browser version just so you can load Portable Adobe Flash doesn’t really make sense.

      4. Thank you for the replies.

        It’s a shame that Mozilla decided to remove the functionality that allowed to have Flash in a portable way :/

        Anyway, although using an old browser doesn’t make (much) sense, I’m guessing that there will be some folks (like myself) that will continue to use it in that way, as there are some old websites that refuse to upgrade their pages.

        Thank you for all the help!

      5. ESR is not exactly old. ESR versions just progress slower function wise, but they patch up security issues like it’s a regular version. I haven’t had time to test it myself if ESR version and Portable Adobe Flash work, but since it’s pre Firefox 71, it should.

      6. Hi!

        I can confirm that it woks on the current ESR (68.5.0esr 64-bit). And yeah, you’re right regarding about ESR, I had in mind the “normal” version of FF in my mind when wrote the comment. My bad.

        Kind regards.

  2. Updated the plugin to version 32.0.0.330 !

    I’ve also updated additional info with how Firefox interacts with plugins and which version needs to be used in order for it to function correctly.
