Firefox is also blocking my site, when we access via Firefox, the layout have been broken cause some content being blocked, not only Chrome. I need to know how to check what happen on my site not fit Firefox security policy. Thanks,

Hello, Who else have any advices for my further actions to solve this? Currently, all images on my site being blocked on Firefox. When we access to one certain image path, firefox show "Reported Web Forgery" warning. Please help me how to solve this issue. Thanks,

Sorry, Mozilla can't do anything for you regarding that Safe Browsing block. Firefox uses data supplied by Google, which controls that data completely.

Looks like Google hasn't seen a problem with that website since 2014-12-28.

And I don't see that your site is currently blocked right now.

Have you tired clearing the browser cache on the affected devices? https://support.mozilla.org/en-US/kb/how-clear-firefox-cache

Yes, I've scanned my site with Google Safe Browsing many time, and result is always safe. But I really can not access to my site via Chrome, you can try it.

With Firefox, all images on my site being blocked and the layout is broken. You can try one link to image on my site: http://printingkiteco.com/wp-content/uploads/2014/12/NEN-1-01-1360x600.png

IE can show it successful but Firefox and Chrome block it with Web Forgery warning. I don't know why this prevention happen.

Maybe your Firefox phishing and malware protection is corrupted? Try disabling it by unchecking the boxes in the Options > Security tab. Uncheck both Block reported attack sites & Block reported web forgeries then press OK.

Then shut down Firefox and start it again. Visit your site and see if it works now. If it does, there may be a problem with your google phish/malware database not updating. It might be corrupt. You can try going back to the options and putting checkmarks on the same options again. It should then try to download new protection files. Hopefully it will stay fixed after that.

I've already tried to access website in other computers, it's same result. How about your result when you access image link which I've posted in previous comment? Chrome always show phishing warning page, Firefox prevent to load all images and break out the layout of website.

Do you have any tool to test a site with Google Safe Browse policy? Thanks for your answer!

So you didn't try clearing the cache? Or try doing a {Ctrl + F5} to bypass the cache and get a clean load from the server?

Using multiple versions of Firefox I have no problems with your website, and I can't test it with Chrome as I don't have it installed.

I have tried to clear cache and reset Firefox/Chrome setting already, but the result is same. If you can find Chrome for testing, you will see the problem more clearly.

When you access my site via Firefox, did you see any images on it?

Thanks for your answer.

I can replicate the problem and get the phishing and malware protection page in Firefox when I open a link that shows as file size 0 in the Web Console (Firefox/Tools > Web Developer). The (older) version of Google Chrome that I have blocks the entire website, but Firefox only has a problem with links coming from http://printingkiteco.com/wp-content/

Do you find any malware or phishing issues on my site? Can you show me why do Firefox has problem when load links from wp-content? Thanks for your review

Thanks @Cor-el, I have decided to change the name of wp-content on my site, it work good after making this. Now, my site is working with no problem, but I still don't know why my site has been being blocked all links to wp-content folder. If you know this before, please give me more explanation about it. Thanks for your support ITS Co.
