Ever since the new Firefox Upgrade a few days ago, my Pinterest has lost all functionality and control. I also had to take the security off of my anti-virus.
I can bring up my Pinterest page and log in, see it, but it's not in the correct, organized order, the pins are not in their normal boxed shapes (but rather rectangular shaped). I can't organize them, move them, etc. When I try to hit the organize button, I get the "select all" option and if I click it, I just get a blank page as opposed to the option of selecting all or various pins, moving, deleting or copying pins. Also, just in general, when I click on a pin to open it, it asks if I want to open it via the Pinterest App or Safari. (I never even use Safari on this computer--it's Windows not Apple). I did check other browsers and the Pinterest is running fine elsewhere; it's just with Firefox *after* this upgrade.
When the upgrade first happened, I was unable to open Youtube videos on various sites or other regular sites I visit as they were "not secure." After browsing Google and reading advice on these forums, I finally just took the protection off of my Bitdfender anti-virus security. Frankly, though, I'm not very happy doing that. I *want* to have that anti-virus running, but I can't open several sites with the Firefox upgrade with it running.
