Running Windows 7 x64, I just upgraded to Firefox 15 and any website that uses Flash causes Flash Player 11.4 to crash. Internet Explorer 9 is fine, and downgrading to Firefox 14.0.1 works fine too.

Anyone else experiencing this?

I was having the same problem.... But I keep forgetting that when you upgrade firefox or it updates automatically ... you need to right click on the firefox start up icon, go into properties, click on the compatibilities tab, and put a check in the "Run This Program As An Administrator" box, then hit apply. Start Firefox, and it should work OK. Problem is...each time you upgrade firefox and/or I think Adobe flash... you need to make sure that box is checked. This is on Firefox 15.0.1 with Adobe Flash 11.4.402.278 all up to date, Windows 7 64bit. All I know is that after I upgraded to the latest firefox and the latest flash, I was crashing when connecting to any site that had a flash item. I have zone alarm anti virus / internet security set pretty high on security... so that might be what is requiring firefox to run in admin. I don't know if admin is less secure, but that is what fixed mine. As a test, disconnect your computer from the internet, unplug from your modem... start firefox, click on tools, then add-ons. Disable all flash items in firefox. Restart firefox and reconnect to the internet. If everything works, except items that require the flash plug in ... you will know that it is flash. The solution that worked for me was to give Firefox admin rights so it could properly interface with the new flash... it's worth a try... then let Moz.org and adobe figure out why. The only reason I had to disconnect from the internet to do this was my home page has a youtube imbed, and it would hang as soon as firefox was started and accessed my home page, then I could not access my tools or anything.

You really want your browser running with the least possible privileges.

Can you try this instead?

All of the 11.x series of Flash froze on me when a page tried to load it in FF or IE. I ran that Fixing Windows Permission Problems with Flash Player and rebooted and all of a sudden Flash was working again. Jeromie, thanks for posting that. Nothing else worked until now... I just hope it "stays fixed".

Back to the original question, yes there's a problem with Firefox 15 & 15.0.1. Even mozilla acknowledges this, but doesn't seem to know what's going on, and the only advice given to this point is to tell users to download a cumbersome diagnostic application:

There have been many posts about this on this forum, too.

But to their credit, the helpful people on this site at least are trying to look into it: http://forums.adobe.com/message/4744651#4744651

Frankly, I think it's high time that Adobe admitted that the Protected Mode needs more development, and to re-issue 10.3.whatever as Flash Player 11.5.whatever, since that was the LAST relatively stable version that didn't crash browsers, eat up CPU, and make trying to operate a PC hell on earth.

Just my two cents.

…and for me, that’s a very good reason just to simply stick with Firefox ver. 14 till they spend some time to rectify the problem. The only irritant is the little pop-up telling me that Firefox 15 is “available for download”. Seeing that is much better than opening ver. 15 and seeing the “Adobe Flash Plugin has crashed” on every video that I want to watch. J thanks for the response.

yes, I experienced the same problem/conflict between Firefox 15 and the latest version of Adobe Flash (11.4.402.265). This isn't the first time it's crashed since the automatic upgrade to Firefox 15. I had to rollback to version 14.0.1 to resolve the problem. I then went into Tools/Options/Advanced and told Firefox to let me decide when to upgrade my version of Firefox. Until this issue is resolved by the developers, I'll be content to run Firefox 14. The rollback to Firefox 14 solves the problem.

Thanks for the response but I tried your suggestion and it didn’t work. Also, I have the very latest version of the Adobe Flash Plugin. Running the setup for Firefox 14 and reverting to that version immediately solves the problem. Until Mozilla spends some time to rectify this recurring problem, I’ll be content to stay with Firefox ver. 14. Thanks again.
