You can check for problems with current Flash plugin versions and try these:

• disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
• disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
• disable hardware acceleration in the Flash plugin

• http://kb.mozillazine.org/Flash#Troubleshooting

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.

I see many many entries on the support site about Shockwave crashing with the exact same suggested fix. IT DOES NOT WORK. Lets do better ladies and gentlemen.

My HP Win7 desktop has been having problems with Shockwave plugin crashes off and on ever since the update to Firefox 25.0.1 and it is getting worse as time goes on. Just about any active media - Youtube, online radio, Pandora, and Spotify - all sound like they have the hiccups - gaps and stops and starts.... then the crashes. On the other hand my ancient Dell laptop, with Win XP and an older version of Firefox is behaving just fine, so the blame cannot be put solely on Adobe.

Did you try to disable hardware acceleration in Firefox and in the Flash plugin and possibly also disable protected mode in the Flash plugin?

Also make sure that your security software isn't causing problems with the plugin-container process.

I have disabled hardware acceleration in FF and the playback on Youtube is marginally improved. However now I am getting frequent "Firefox is non-responsive" messages - usually when I open a new tab or am just starting up.

As for disabling it for Adobe, that has been a wash so far. I read the instructions, went to the "version page" but where instructions indicated I should get a drop down menu for settings all I get is plain text - nothing to click on. I cannot tell if that is because I am using Firefox, and it is simply not giving me the link or if the Adobe page is having issues of its own.

My security is AVG Internet Security 2014 and it has not been interfering with anything as far as I can tell. It was playing nice with all my software before the latest FF upgrade (the same one which wiped out my bookmarks and passwords), so since all my recent tribulations date from that event it seems unlikely that AVG is responsible.

I have been a staunch supporter of Mozilla and Firefox for many years, and I always have felt comfortable recommending it to friends despite the occasional hitch, but while I really don't care much for Chrome - mostly because of privacy issues - I must say I am disheartened by this latest update.

Hi slywlf54, here is how you can disable the protected mode feature:

(1) In a My Computer or Windows Explorer window, open this folder:

C:\Windows\SysWOW64\Macromed\Flash

If that folder does not exist, then you are using 32-bit Windows, and you can open the following folder instead:

C:\Windows\System32\Macromed\Flash

(Note: This folder exists on both 32-bit and 64-bit Windows, but on 64-bit Windows Firefox uses the Flash player in the SysWOW64 folder instead.)

(2) Check for a file named mms.cfg:

(A) If mms.cfg exists, drag it to your Documents folder where you can edit it without being bothered about administrator privileges

(B) If mms.cfg does not exist, open your Documents folder, right-click > New > Text File and name the new file mms.cfg (if you have Windows set to hide file extensions, this may create a text document instead of a CFG file, in that case, see this article: http://support.microsoft.com/kb/865219)

(3) Open mms.cfg from Documents into a text editor such as Notepad. Add this on its own line (I put it last):

ProtectedMode=0

Save the file and close Notepad.

(4) Hold down the Ctrl key and drag the mms.cfg file back to the Flash folder to make a copy there, keeping the original in Documents

This change should take effect the next time you restart Firefox (allow a few minutes for all the Flash processes in memory to terminate after exiting Firefox).

OK - the system would not let me drag that file anywhere, so I copied it to Documents, did as instructed, renamed it and copy/pasted it back in the original folder. Oddly enough the system had no objection to two identically named files, won't let me move the original out of the folder, but seems to be totally ignoring my doctored one. So now I have an old and new version of the cfg file in My Documents and in the Flash folder, and playback issues continue. I am open to suggestion - while my skills are limited I am pretty good at following clear instructions - as yours were, and thank you!

Hi slywlf54, I'm pretty sure Windows will not tolerate two identically named files in the same folder. There must be some difference. Did you make the change so you're viewing the true file extensions?

Another way to edit a file in that folder is to run Notepad as the administrator. If you open the Start menu to where you can find Notepad, then right-click it and choose Run as administrator, you then should be able to edit the original mms.cfg. (Or perhaps it won't let you edit while Flash is running? I haven't tried it for so long, I can remember.)

Note that Windows hides some file extensions by default.

Among them are .cfg and .ini and .js and .txt, so you may only see a name without file extension.
You can see the real file extension (type) if you open the Properties of the file via the right-click context menu.

That shows me simply a read-only 'file folder' for the original while the notepad file I renamed after editing it shows as a .cfg file Now what?

OK - I reset my folders to show extensions on all files, renamed the old one to mms2.cfg and then fixed the doctored one to mms.cfg and at least for now that seems to have done the trick - the video I just put on has been playing with only the occasional hiccup. Not perfect but a lot better. Thank you!
