Disable all extensions
To determine whether a faulty extension is causing your problem, you can disable all of your installed extensions:
At the top of the Firefox window, click on the Firefox button (Tools menu in Windows XP), and then click Add-ons. The Add-ons Manager tab will open.
In the Add-ons Manager tab, select the Extensions panel.
Click the name of an extension in the list to select it.
Click Disable to disable the selected extension.
Repeat this for each of the other extensions in the list.
Click Restart Firefox.
PS: I didn't disable all extensions, only RealDownLoader. And that worked.
And my Photobucket account is working ok again too.
I hope it works for you too, Joc.
I reset Firefox and so all of the add-on extensions like that one are already gone. I think it has something to do with FireFox not meshing correctly with Flash. But Adobe has killed all the Flash 10 downloads. Why would they do that? So what if I like a previous version (that worked) why can't I download that one? No...Adobe apparently decided they know what is best for me.
