As of 6/10/12, Adobe flash 11.3 would NOT work in Firefox 13. On any web site. I had no problems with IE. I run Vista, latest update.
None of the posted answers on this site solved my own particular problems.
This is how I successfully addressed the issue:
1) I removed all Adobe Flash caches as directed in http://helpx.adobe.com/flash-player/kb/flash-playe
2) I uninstalled all instances of Adobe Flash through Programs and Features in the Control Panel.
3) I restarted my computer and Firefox.
4) I opened YouTube in Firefox. It directed me (automatically) to install Adobe Flash 126.96.36.199. Though I was aware of that version as the version previous to the current version (11.3), I was unable to locate it for download on the Adobe site.
Flash then worked again in Firefox 13.0.
Solved! Go to Solution.
My initial fix unfortunately only lasted for about an hour.
As what I thought would be my final coup de grace, I disabled Adobe Flash's protected mode - http://forums.adobe.com/message/4468493#4468493 .
That did the trick. Flash now works in ALL web sites. Google Earth also works.
Interesting that YouTube provider a link to an older installer. I assume it was a link to somewhere on adobe.com and not their own copy? The download manager (Ctrl+j) might let you see the source if you right-click that download and choose Copy Download Link and paste it into a reply (or your favorite text editor).
I followed up on your request. I uninstalled Adobe Flash 188.8.131.52. I removed all YouTube cookies. I rebooted my computer.
This time when I went to YouTube I was asked to install Flash, but this time I received the following links:
So, this time, YouTube downloaded 11.3, and it works!
(What do you think was going on before that made 11.3 malfunction on my computer?)
It's a bit of a mystery. In several other threads, people are reporting problems with 11.3 and trying to go back to 11.2. Perhaps clearing the caches helped in your case??
Thanks, Jeff. Except that I cleared the caches before the first install (of Flash 11.2 as selected by YouTube). I didn't clear the caches before the second install (of Flash 11.3 as selected by YouTube). I cleared YouTube cookies before both installations. ...All very confusing to me..
Nice that it's back working, and I'm using the latest version.
There are a number of active threads concerning the latest Flash player plugin (11.3) and the latest Firefox (13). Not all users are experiencing the same issues, but things to check include the following:
- Conflict with Realplayer Browser Record plugin (to disable this, open Add-ons from the orange Firefox button or the classic Tools menu and look under the Extensions and Plugins categories)
- Conflict with Flash 11.3 Protected Mode (see Adobe Forums: How do I disable Flash Player's protected mode for Firefox?)
Scanning down the front of the forums probably will yield additional suggestions: https://support.mozilla.org/en-US/questions
Does any of that appear promising?
Does it help if you disable all other plugins and maybe extensions as well as a test?
I disabled the RealPlayer plugins, that didn't resolve anything. YouTube is still saying "An error occurred, please try again later."
I do not have any more time to dedicate to this, and will wait until the problem is solved generically.
It would help if Adobe would allow Flash version 11.202.235 to be downloaded, but they block its download. It was the last reliable, functioning version that I used.
