Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?

I've seen that post, but I have exactly the same problem as vrm3. It all worked before the upgrade and now it doesn't. I need it to work. Looks like I'll be heading back to version 41.0.3 and turning off automatic updates.

If you read that thread, you know you have these options in Firefox 42:

Once you start the video:

• To save the video
  • right-click the video > Save Video As
  • right-click near the Vine logo > This Frame > View Frame Info > Media tab

• To copy the address of the video
  • right-click the video > Copy Video Location
  • right-click near the Vine logo > This Frame > View Frame Info > Media tab

What am I missing?

I don't get a save video option when I right click on it.

I have no idea what a vine logo is, and do not see one, so this made no sense. (A lot of things in these threads are not obvious to everyone).

However, I did find the "this frame" option when I right clicked on the video.

Thanks for your help. Really did not want to downgrade to the earlier version.
