Adobe seems to have no explanation of these file types anywhere on it's support site. Why don't you explain this to users? A Readme.txt file right inside of the downloadable ZIP file would be a great idea.
Please note, that unless you have a compelling reason to use a previous version, Adobe highly recommends always using the latest version which contains security fixes for known security vulnerabilities, which in most cases are actively being exploited.
Yeah, these distributions aren't intended for end-users. They really exist to help developers of Flash content to ensure backwards compatibility. You should *not* run an old version of Flash Player on a machine that browses arbitrary websites.
Normally I would agree with no rolling back, but Oct, 2017 there is a incompatibility problem between VMWare and Adobe Flash (Shockwave Flash crashes with vSphere Web Client and vCloud Director (2151945) VMware KB ) - so the Main point is we need to understand the various versions/extension that in the Zip of Adobe (example: fp_27.0.0.130_archive.zip), and what all extension do, as for example how is flashplayer25_0r0_148_win.exe different then flashplayer25_0r0_148_winax.exe other than above statement on ActiveX .. as I've just wasted over 4 hrs with various versions of Browsers but nothing seems to work ..
One of my web browsers is Firefox ESR 10.0.7 and it is a PORTABLE version of Firefox that apparently needs a different Flash Player plugin than the normal Flash Player plugin that regular versions of most web browsers require.
I do not want to install the most recent Flash Player plugin PORTABLE version because I've read about problems with it and that's the only version that this Firefox ESR will give me the option to download and install when I try to install the needed Flash Player plugin through the browser.
I ran into the same problem with the version of Firefox portable I tried. I ended up ignoring the folder (with the text file) that they provided and created my own "plugins" folder alongside the firefox executable.
As for why I went with 10.3 over 11.4, that was mainly because we added protected mode in Flash Player 11.3. While this might work (it didn't with my first attempt), it adds a layer of complexity that I didn't want to deal with. If you need some of the newer features of 11.x, then y
2) Since portable apps can work from a Flash drive and they don't work from or see the many system files that are contained in system software and 3rd party plugins, like Flash, usually they contain their own plugins if they need them, such as the Flash Plugin that this PORTABLE browser is asking for.
4) And when I installed my newer normal Firefox browser (not the portable version) over the previous one, it didn't need to have the Flash Player plugin re-installed... it just saw my existing Flash Player plugin... but this PORTABLE Firefox ESR is not seeing that existing Flash Player plugin v 11.2.208.228 like my other regular installed Firefox is.
The nppdf32.dll file that you are recommending that I copy and paste in to my Firefox ESR PORTABLE plugins folder is identified as a PDF plugin, not a Flash plugin, thus the name, npPDF32.dll. So I'm not sure why you would expect the PDF plugin to work as a Flash plugin.
And I checked and there is no Flash Player plugin in the plugins folder for my normal Firefox browser. As I said before, there is only an "Adobe get Plus Plus 16291" plugin, and it is named "np_gp.dll". There is one other plugin file in that folder and it is named "np-mswmp.dll" and it is a "Microsoft Windows Media Player Firefox" plugin.
There seems to be no rhyme or reason to follow to try to find this plugin that does apparently exist somewhere on this computer... that's why I'm assuming that my normal Firefox browser is using the system Flash Player plugins that show up under Control Panel>Programs and Features>Adobe Flash Player 11 Plugin (11.2.202.228) and Adobe Flash Player 11 ActiveX (11.2.202.235)... but I don't know where those actual plugin files would be located to try to copy and paste them in to my Firefox ESR PORTABLE plugins folder, and I fear that they wouldn't be the right types of files to place in that folder anyway.
Now, in my Google Chrome browser folder at User>AppData>Local>Google>Chrome>Application>21.0.1180.89 there is a Flash Player file called "flashplayerapp.exe", but that actually appears with the Flash Player icon and it is an exe file, not a plugin file, so I doubt that would translate to be used as a plugin for Firefox ESR PORTABLE. I've also read that Google Chrome, Internet Explorer and Safari all use a different type of system to display Flash content, different from the Flash Player plugin that Firefox requires.
And as I wrote above, I've already asked this same question on the Mozilla Firefox help forum and no one could answer it... all I got was some guy who kept trying to tell me to use the Flash Player 10.3 instead but he couldn't tell me how to get that in to my Firefox ESR PORTABLE plugins folder, and we went round and round on the subject. There was one other guy who kept talking about Linux, for whatever reason, and he kept getting Linux version numbers mixed up with his conversation about Firefox... I don't think he was actaully reading my original question very well and he really didn't seem to be following along.
And for a minute or two, I thought it was working. In my first tests in the PORTABLE Firefox browser I'm testing with, it was actually playing some YouTube videos, but then I found that not all YouTube videos apparently rely on Flash to play... apparently some do and some do not, and I found that most of them do require Flash to play. I had tested with some of my own videos that I uploaded to YouTube in the past in my first tests today and they played just fine, but then I started testing with some other Flash YouTube videos and they would not play and I got both the yellow bar at the top of my window telling me to download and install Flash as well as the red banner across the video player that told me I needed to install Flash.
Let me also make it clear that I'm testing this on other sites with Flash videos besides YouTube, and webpages that have relatively simple animated Flash graphics, and those alternate tests are showing that the Flash Player plugin for this PORTABLE Firefox still will not work either.
So to spite everything, I tried actually downloading and installing the newest Flash Player plugin, 11.4 something, (which I was trying to avoid) through the browser, and that only proceeded to overwrite my Windows system Flash Player plugin and it DID NOT place any Flash Player plugin files in the PORTABLE Firefox plugins folder.
I had pasted in the files you recommended in to the PORTABLE Firefox plugins folder, and I actaully included ALL the files from that Windows system Flash plugin folder for this test, but unfortunately that didn't work, and even after I tried changing the name of that one file, it still didn't work.
So here, below, I'm including an email letter that I've now written to a Tor Browser support email address where I had been corresoponding previously. The "Tor-Firefox" web browser is the PORTABLE Firefox ESR web browser that I've been referring to. This is what I wrote, which pretty much sums up everything I've tried and been unsuccessful with so far...
I've now tried everything and I cannot get ANY Flash content to play in this Tor-Firefox ESR web browser, even though I've tried installing the Flash player plugin that this browser asks for when I'm on a YouTube page (and even though this computer already had a current Flash Player plugin installed previously).
Let me make it clear that privacy is not important to me right now during this quest to make the Flash Player plugin work with this Tor browser... I can reset any settings for maximum privacy later when I go back to that purpose for using Tor... right now, I'm just trying to make the Tor browser play Flash content.
So even though I've UNCHECKED the Torbutton>Preferences>Security Settings>Disable plugin during Tor usage box, and I installed a new Flash player plugin THROUGH this browser, and I even set it to allow all scripts because I thought maybe that was complicating things, IT STILL WILL NOT PLAY FLASH CONTENT OF ANY TYPE.
Now, this, explained below, could be part of the problem that I'd like to ask for your help or SOMEONE's help with there in your department...
If I go to the Tor Browser folder on my hard drive at C:>Tor Browser>FirefoxPortable>Data>plugins there are NO Flash plugin files that show up in that folder even after I install a new Flash Player plugin THROUGH this browser... I believe that is why it will not play Flash content.
All it does when I install a Flash Player plugin through this Tor browser is to overwrite my Windows 7 system Flash Player plugin, but it does not actually place any Flash Player plugin files in the C:>Tor Browser>FirefoxPortable>Data>plugins folder, so that's why this PORTABLE version of the Firefox ESR browser will not play any Flash content... and it doesn't work from the Windows system Flash Player plugin the way that my normal Firefox (NON-TOR) web browser does. My other Firefox web browser sees the the Windows system Flash Player plugin just fine and it does play Flash content correctly.
There is, however, one text file that comes stock inside the Tor browser plugins folder and when it is opened it says, "Place Firefox plugins in this directory (Flash, Shockwave, etc)".
