I am having the same problem as well -_- I think I am going to go back to the last firefox version before this because I never had this problem before.

Having the same problem. Facebook doesn't work either and Flash Player errors. Coontent not loading. Sucks!

I started to have same problem after firefox was updated to 3.6.7 this morning. Firefox just jams when you try to enter a site wich has flash components. Its not flash player fault because I tested that all the sites and they work fine in other browsers(opera, chrome)

Im Having the same problem with flash player and acrobat as well the trouble shooting isn't helping and I keeps telling me I have to install a missing add on which is GP.xpi

Same problem...

Anyone have a solution to this yet? Sounds like a lot of people are running into this.

Same exact problem. First the LastPass issue and now this. I'm not going to allow my FF to automatically update anymore. this is getting ridiculous.

Same problem on a windows XP computer. Can load my home page but can't see anyone else's pages or status.

All that plus my mouse isn't working right. Where's the help???

For me flash vids juts go blank but audio continues.

Same problem with Ubuntu Karmic here, waiting for fix.

same

same AND ITS ANNOYING

I Finally got it to load it. I went to a page I know had a flash vid and it asked if i wanted to install the updated flash plugin I said yes and it installed. But why wont it install on its own on an update

This really sucks!!!!!

Can someone post a fix please?? This is driving me insane. Not video streaming seems to work anymore. It just hangs there. Firefox, don't you think it's about time you did something about this release??

Not sure if it is related, but multiple internal links on Amazon.com are not working with FF 3.6.7. It's not my computer, as IE is working fine. Please fix ASAP, thanks.

Same problem in W7. Firefox is starting to FAIL with every new update.

Same issue. About half the websites I use won't display correctly including gmail, cnn, yahoo. Switching to Chrome until this is resolved.

After I upgraded firefox to 3.6.7, flash videos stopped working. Instead of playing videos theres this big black rectangle and in the midst a link to adobe flash player which takes to the adobe web-site. Even after installing the flash, it still doesn't work!

From about:plugins in the firefox:

Shockwave Flash

   File: /home/xxxxx/.mozilla/plugins/libflashplayer.so
   Version: 
   Shockwave Flash 9.0 r124

Yeah there's no adobe flash!! Unless Shockwave and adobe are the same. Should I feel stupid? :P

Hey fellas I got this problem fixed, Here's how I solved the flash problem with firefox:

After I updated firefox to 3.6.7, the flash based videos stopped working and interestingly audio only in youtube.

First I removed all types of flash plugins from /usr/lib using the terminal (sudo rm /usr/lib/mozilla...........)

Checked aboutlugins in firefox and interestingly flash version 9 still remained undeleted (coz the file is hidden in .mozilla folder) and therefore removed that too.

Then I downloaded and installed latest flash version 10 from the adobe website directly.

Restarted firefox and it now works like a charm.
