No sound in Firefox 64.0 64-bit on Tahr Pup 6.0.6 x64

[bigpup]

The four repositories in PPM are:

ubuntu-trusty-multiverse
ubuntu-trusty-universe
puppy-noarch
puppy-tahr64

PPM>Configure>Choose Repositories.
See if you can select ubuntu-trusty-main, to add it as a selected repository.
Should now see it in the list of repositories in PPM main window.
Now see if libgtk-3 will show up in a search.

Yes! That was the problem. I had not selected ubuntu-trusty-main. When I did, it appeared in the list of repositories in the main PPM window. And I found libgtk-3. Great. Somehow you knew that libgtk-3 was in ubuntu-trusty-main. I wonder how.

Thanks for the help.

PPM and repositories are a mystery. Maybe I should start a new forum topic on using PPM.

For example, in PPM>Configure (also known as PPM>Tools), when I click on "Add new repo" nothing happens. I don't understand why not. Does that mean there are no more repositories to add?

And how is one to know when one is searching all the repositories for one's version of puppy? Is there a list of repositories for each version somewhere?

Thanks again.
