From your Safari menu bar click Safari / Preferences then select the Security tab.
At the bottom of that window, deselect: Ask before sending a non-secure form from a secure website.
If that doesn't do the job, open the Terminal app (Applications / Utilities)
Copy and paste the following command.
defaults write com.apple.Safari DebugConfirmTossingUnsubmittedFormText NO
To undo this… same command but type Yes.
Hi there. I also get this. No solution has worked. I've turned off the preferences checkbox, tried this command in the terminal, and I still get this dropdown dialog box twice on the homepage at break.com. There is no security and there is no form, so I have no clue why it's even coming up. The site works fine in Firefox.
That also happens to me on the Break site, but even more frustratingly on the site I visit most. It didn't happen for 10 years prior to upgrading to Lion. Check box is unticked and Crome/Firefox don't give irrelevant message.
Any fix on this, as I much prefer Safari, but this is driving me mental!
