Hello again :-), if the problem is the Video Download Helper, see the reply in my previous link, see also : https://support.mozilla.org/en-US/kb/install-older-version-of-firefox

thank you

Installing older versions of Firefox isn't supported, as it will leave you vulnerable to a whole host of security issues, stability problems and other issues. What problem are you having with Firefox 36?

Video download helper does not work, they have a beta version that i am having all kinds of problems, it is downloading the same news item over and over and over. I guess I will disable it. I tried another helper that was recommended by this forum ? video down loader professional and it was kind of doing the same thing. I liked VDH because it downloaded other videos not just you tube and familiarity with it helps

I just re read the answer and I did follow the link and downloaded, I will try one of the other links and see what happens. Thanks for responding more than once appreciate it very much.
