Go to your YOU page and click on INSTRUCTABLES tab, then click FAVORITES.

now i feel really stupid. I finally found it a bit more buried than i expected.

oh! thanks so much, i get it ;D

See this thread, it has people mentioning similar problems, and solutions that work for them.

Thank you very much. That thread pointed me in the right direction.

I finally figured out Instructables doesn't play nicely with the Ghostery plugin on my MacOS/Firefox setup. I made a whitelist exception for 'instructables.com' in Ghostery - problem solved!

Mostly solved, anyway. I use Ghostery for good reasons, and it's frustratingly weird that Instructables can't cope with it. Ghostery is a featured add-on at Mozilla, and I've never been troubled at any other site...

...Anyhoos, the fave heart did come back after I disabled Ghostery on Instructables. ;)

Hmmm, I wonder if it is the Ghostery plugin for my FF on Win7 doing the same thing...

Take a look at the picture, you might have to wait a few seconds, till it appears

Thank you, that was helpful! Now I know where to look, and alas, it's not there. Might be a browser setting. I can see it in IE, but not in my regular browser.

I have that "problem" too. I have done what you suggested by going to the "you" page. No where on that page is a section called "stuff you like". I am soooo dissapointed. I should have just bookmarked all those projects! That fave button was useless.

Solved your own problem?
