sorry ed,
i personally think, that it is a firefox problem and indeed i do not expect you to solve that firefox problem. my intention to look or post here was, that it might have been a known problem or at least could have been worked around by any more or less simple java script. (or even better a simple value to be set.)
for sure the problem does NOT come from any other plugin. i put same code in another scenario where absolute NO plugin is active! (basic WP current version 4.2.2 no hacks and not even the dante recommended plugins active) > same result.
if you’d like to have a look in your own scenario here’s the simple testing code …
[blank_spacer height="0px" spacer_id="buttons" spacer_name="Buttons" width="1/1" el_position="first last"]
[one_third][sf_button colour="accent" type="standard" size="standard" link="/scroll-testing-or-whatever-your-pageurl-is/#first" target="_self" icon="" dropshadow="no" extraclass="smooth-scroll-link"]First[/sf_button][/one_third][one_third][sf_button colour="accent" type="standard" size="standard" link="/scroll-testing-or-whatever-your-pageurl-is/#second" target="_self" icon="" dropshadow="no" extraclass="smooth-scroll-link"]Second[/sf_button][/one_third][one_third_last][sf_button colour="accent" type="standard" size="standard" link="/scroll-testing-or-whatever-your-pageurl-is/#third" target="_self" icon="" dropshadow="no" extraclass="smooth-scroll-link"]Third[/sf_button][/one_third_last]
My problem with anchors in firefox:
[one_third]
[blank_spacer height="15px" spacer_id="first" spacer_name="First column" width="1/1" el_position="first last"]
<h5>First Column</h5>
This my demo content for the first column.
[/one_third][one_third]
[blank_spacer height="15px" spacer_id="second" spacer_name="Second column" width="1/1" el_position="first last"]
<h5>Second Column</h5>
This my demo content for the second column.
[/one_third][one_third_last]
[blank_spacer height="15px" spacer_id="third" spacer_name="Third column" width="1/1" el_position="first last"]
<h5>Third Column</h5>
This my demo content for the third column.
[/one_third_last]
[blank_spacer height="60px" spacer_id="" spacer_name="" width="1/1" el_position="first last"]
thanks again for your support!
and yeah, if you come across the solution someday, let me know! 😉
best,
