Firefox and youtube - adobe flash slowness

Recently youtube is so slow using the adobe flash. (i mean not the html5, as with html5 everything is fine). I have latest firefox 29.0.1 with latest adobe flash player. When i try to use the volume meter or pause-start the videos, it is laggy.

I have uninstalled adobe flash recently. When I need it, I start Google Chrome or Opera.
Youtube works perfectly without flash.

Can I install the Flash Plugin for Firefox, and the Adobe Flash application program, on the same machine?

PC with Win 7 Home Premium 64-bit
Firefox 33.1
Shockwave Flash 15.0.0.223 installed as a Firefox plug-in.
Everything performs perfectly, and I particularly like the fact that when I encounter a file (usually video) on the web, I can ACTIVATE ADOBE FLASH on a once-only basis, rather than ALWAYS FOR THIS SITE.
So here is my question. I encountered a .SWF file on the web, and played it through the plugin. I then downloaded the file to my desktop. From the desktop, there does not seem to be a way to play it through the Firefox Plug-in. Is this correct - am I missing something?
In order to play the file, do I need to install a copy of Shockwave Flash or Adobe Flash Player as a standalone application program on my machine? Is it OK to have both the standalone application and the Firefox plugin on one machine? By the way, I am not interested in using WMP as the player.
Thanks
Bill

VLC Player looks like a nice application, and it will play FLV files. However, it will not play .SWF files, which was the subject of my initial query. I admit that I am a little confused about the difference between .SWF and .FLV, since they are both called Flash files. My bad. I would love to find a standalone player that will handle both. Nothing fancy required - just play the file!
As a side note, I downloaded VLC Player from the link you suggested. It installed easily and worked well. However, a Google search reveals that there are a number of sources for corrupted versions of the player, which contain malware. Thank you, Fred, for a straight steer.

when i wath youtube adobe flash crashed and in instell last firefox and the last adobe flash

A couple of things:
* Upgrade to Firefox 13 (you're currently running 12). Select Firefox > Help > About Firefox to upgrade.
* Check if your Flash plugin is out of date on this page: https://www.mozilla.org/en-US/plugincheck/. If it is, follow the instructions on the page for upgrading Flash.
Hope this helps!

I am sick and tired of Firefox crashing from Adobe Flash player. All support statements say to reinstall and that doesnt solve the problem!

I am sick and tired of your Firefox not supporting Adobe Flash player. Windows explorer no problem it works fine. All of your support statements tell me to reinstall and I've tried that more than once and nothing improves! It is slowing up my computer, and I have a windows folder with 4.8Mb of auto generated crash messages!

If you have problems with current Shockwave Flash plugin versions then check this:

Firefox crashes after adobe flash 11 upgrade

I have Win7 (64). My Firefox 14.0.1 was working find with Adobe Flash 10. When Firefox upgraded to 15.0.1 and simultaneously upgraded to Adobe Flash 11. Now Firefox crashed as soon as I go to a site with Flash content (like cnn.com or youtube.com). As soon as I uninstall Adobe Flash completely, Firefox starts to respond again (but of coarse without displaying any Flash contacts as it was uninstalled). I even tried downgrading back to Firefox 14.0.1 and reinstalled Adobe Flash 11, and I get the same crashing results. As well as the same results when I uninstall Adobe Flash (meaning that is responds again, but without displaying Flash content). I also tried the same sequences in safe-mode, but still have the same issues.
I am seeing lots of posts regarding trouble with the new Adobe Flash 11, but no definative solution. Can someone please assist me with this. Or at least instruct me on how to downgrade back to Adobe Flash 10. Their site is not clear on how to do this.
Thanks
BTW - I have a second computer that is a complete cloned image of this machine (the only difference is the hardware setup is different, with different respective drivers). This second computer is not having any problems with Firefox 15.0.1 and Adobe Flash 11. Can this problem be caused by a hardware issue?

I want to download and install adobe flash player. When I do so one occur. A dialog box appears but it has no run option but a save file or cancel option.

# Question
I want to download and install adobe flash player. When I do so one of 2 things occur. A dialog box appears but it has no run option but a save file or cancel option. The other is if the proper dialog box appears, I agree and the a different box appears and there is foxfire with a red circle with a diagonal line across is appears.

I find the easiest way to install Adobe Flash is to use the manual installers. You just need to download the installer to your computer, then run it to install Flash. For more details see http://kb2.adobe.com/cps/191/tn_19166.html#main_ManualInstaller
That link states you should uninstall earlier versions, as you don't have the version of Flash used by Firefox you can skip that step.

I just loaded Yosemite on my Mac and now adobe flash won't work in Safari 8.0.4 . Does anyone have a solution ?

I just loaded Yosemite on my Mac and now adobe flash won't work in Safari 8.0.4 . Does anyone have a solution ?

If you can't install or update Flash, follow these instructions.
If you have installed the latest version of Flash, please take each of the following steps that you haven't already tried. After each step, relaunch Safari and test.
For a "blocked plug-in" error, see Step 4.
For a "missing plug-in" error, start with Step 8.
Back up all data before making any changes.
Step 1
You might have to log out or restart the computer before a Flash update takes effect.
Step 2
From the Safari menu bar, select
          Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data...
and confirm. Close the window. Then select
           ▹ System Preferences… ▹ Flash Player ▹ Advanced ▹ Delete All...
In the sheet that opens, check the box marked
          Delete All Site Data and Settings
then click Delete Data. Close the preference pane.
Step 3
If you're only having trouble with YouTube videos, log in to YouTube and load this page. You may see a link with the text "Leave the HTML5 Trial." If so, click that link.
Step 4
a. If you get a warning of a "blocked" or "outdated" plug-in, then select the Security tab in the Safari preferences window. In the list of plugins on the left, there should be one—and only one—entry for "Adobe Flash Player," showing the same version number that you installed. Select that entry. On the right there will be a list of websites for which you have specifically allowed Flash, if any. It's normal for the list to be empty. Below that is a menu labeled
          When visiting other websites
From that menu, select either Allow or Ask.
b. If you still get the alerts, then go back to the Flash Player preference pane and select the Advanced tab. Click Check Now. Quit and relaunch the browser.
c. If the alerts still persist, triple-click anywhere in the line below on this page to select it:
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources
Right-click or control-click the highlighted text and select
          Services ▹ Open
from the contextual menu.* A folder should open. Inside it, there should be a file named "XProtect.meta.plist". If that file is missing and you know why it's missing, restore it from a backup or copy it from another Mac running the same version of OS X. Otherwise, reinstall OS X.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
Step 5
In the Safari preferences window, select the Advanced tab and uncheck the box marked
          Stop plug-ins to save power
Step 6
Open this folder as in Step 4:
/Library/Internet Plug-Ins
Delete the following item, or anything with a similar name, if present:
          Flash Player (failing).plugin
You may be prompted for your login password.
Step 7
Re-download and reinstall Flash. Download it from the domain "get.adobe.com". Don't click a link from any other website, including this one, because you can't trust links. They may be an attempt to trick you into installing malware masquerading as Flash. Type the address into the browser window. Never download a Flash update from anywhere else.
Step 8
If you get a "missing plug-in" error, select
          Safari ▹ Preferences... ▹ Security
from the Safari menu bar and check the box marked
          Allow (or Enable) plug-ins
Then click the button marked
          Manage Website Settings...
if present and make sure that the website is not blocked for Flash.
Step 9
Select
          Safari ▹ Preferences... ▹ Extensions
from the Safari menu bar. If any extensions are installed, disable them.

How do I close firefox to install Adobe Flash Player

How do I Close Firefox to install Adobe Flash Player?

There are 2 versions of Adobe Flash; an '''ActiveX version''' for IE only and a '''Plugin version''' for most other browsers including Firefox. On a Windows system, you should always update both individually.
#'''Using Firefox''', go to the following direct download link and SAVE the download to your desktop so you can find it later: http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe
#When the download is finished, close Firefox (File > Exit '''''OR''''' Firefox button > Exit)
#Click or double-click on the file you just saved to your desktop
#*In the installation window that appears, click the box to the left of "I have read and...." to place a check mark in the box
#*The "Install" button in the lower right corner will now be highlighted, click it.
#*The installation is quick.
#Start Firefox and test your installation here: https://www.adobe.com/software/flash/about/

That crash appears to be casued by the Facebook plug-in.
Create a new account (systempreferences -> accounts or Users & Groups on 10.7 and 10.8), make a new Library in that account, import some shots and see if the problem is repeated there. If it is, then a re-install of the app might be indicated. If it's not, then it's likely the app is okay and the problem is something in the main account.

How do i find and delete adobe flash installer

how do i find and delete adobe flash installer

It is likely in your Downloads folder if you downloaded it from Adobe. If you downloaded it from someplace else, please add more details.

Every time i turn off my computer and back on i have to unistall and reinstall adobe flash player

Everytime i turn off my computer and back on i have to unistall and reinstall adobe flash player11.8 . I have tryed everything i could find on the internet, nothing helps. please help. I wish i could contact adobe directly but don't know how. Been trying to fix it for a week.

Download and save the uninstaller Save it to your downloads folder - DO NOT run it yet.
Download the Adobe Flash Player installer directly by right clicking one (or both) of the following links and selecting "Save Target as"(IE) or "Save Link as"(other browsers).
Flash Player for ActiveX (Internet Explorer)
Flash Player Plug-in (All other browsers)
Save the installer(s) to your downloads folder - DO NOT run it(them) yet.
Reboot your system.
BEFORE you run anything else, locate and run the uninstaller.
When it finishes, run the installer(s) to put Flash Player on your system again.
If you use IE see also:Enabling Flash Player in Internet Explorer and: ActiveX Filtering in Internet Explorer

I have downloaded and installed Adobe Flash Player, but it was installed to a "disk image". I don't know what this is and I cannot see anything that requires Flash Player. What am I doing wrong?

I have downloaded and installed Adobe Flash Player, but it was installed to a "disk image". I don't know what that is, but I cannot view anything that requires flash player. What am I doing wrong?

Thanks for your help, but that didn't do any good either. I have been double clicking from the download files, double clicking on the "install adobe flash player", closing the anti virus, closing Safari, watching the install progress and clicking finish. It indicates that "flash player" is installed, but every time I try to view something requiring flash player, it tells me I must download it. It shows up in the "system preference" and from there I can make some changes, but it still won't let me view anything requiring "flash player". It does not show up in my apps like Adobe Reader does. It shows up in the "downloaded files" section of "Finder". I'm getting really perplexed over my inability to get this right.
