I had a browser based problem with Firefox yesterday where my animation wasn’t running smoothly, even the latest version, but it was running fine in Chrome and Safari.
I searched online for a bit but didn’t find a solution. I was, at the same time, trying to remove the dotted line that’s displayed when clicking a link in Firefox.
After some trial and error it turne out both things were solved by the same thing.
Solution:
In css add:
a:focus{
outline:none;
}
FIXED!
If I knew what I was doing...
