I don't see an issue with the screenshot you posted. Can you explain more in depth about what happens when you try to play a video? Does it not play, does it crash, what?

Your flash player needs to be updated. Go to get.adobe.com/flashplayer

This is what happens when i click to play video (as shown in image below) and displays a message "An error occured , please try again later". And i do have latest version of adobe flash player because before posting problem over here i updated my flash player and its from the same link that you gave me in your reply .

the above mentioned url may not work...so here is the previous snap (the snap mentioned by the url in my question)

Did you try to disable the Shockwave Flash 10.1 r999.Gnash 0.8.10 plugin and only keep the 11.2.202 Flash version?

Reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Hold down the Shift key and left-click the Reload button
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Command + Shift + R" (Mac)

Clear the cache and cookies only from websites that cause problems.

"Clear the Cache":

• Firefox/Edit > Preferences > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

• Firefox/Edit > Preferences > Privacy > Cookies: "Show Cookies"

i did all as u said regarding flash, cache and cookies but none helped

and i would like to add one more thing over here that i use TOR browser sometimes which gets configured by firefox and i am surprised that i am able to view videos with no problem in TOR(though TOR use all addons and plugins of firefox) but i am unable to view in firefox browser . is there any clue regarding this?????

anyway thanks to all of u...and i found my solutions by the way.the solution was tricky instead... and mozilla should have removed that flaw :\ have a nice day to all of u :)

AFAIK then TOR disables all plugins, so Flash shouldn't be used. It is possible that that makes the site use the video tag and the built-in HTML5 media player (media.gstreamer.enabled).

Actually when i installed updates from ubuntu then there were many more directories of firefox's PLUGINS where i had to manually move ".so" file of adobe flash player to complete the updates and get plugins working perfectly and when i did that then my browsers started working smoothly . and TOR asks you if you want to disable plugins or not and right now i can play videos in both TOR and firefox smoothly. and thanks to you for your quick response.

Moses, the 11.2.202.336 is the latest version for Linux from Adobe.
