The above site was showing an error yesterday when entering the URL which would account for the Chromebleed popup since they are developed by one in the same.Chromebleed screenshot now below
HeartBleed-EXT 3.0 for Firefox is from a different developer but the extension itself doesn't check a site but uses the web service of Filippo Valsorda . The developer of Chromebleed.You can go to this site https://filippo.io/Heartbleed/ and enter a URL manually to check it however if you are using Heartbleed-EXT 3.0 (Firefox) or Chromebleed (Chrome) they are both going to use the mentioned site to check for the vulnerability.

Note to find out if this site was vulnerable for sure was hindered by the fact that this site is malwaretips.com
so when you go to check they said you have to start the url with https: this url doesn't start with that,so it had me puzzled,
so to me i was like you guys need to be approached about this matter.& after a week or more of posting & asking,you have now address this matter,I love you guys but for this situation & how admin went about it you suck real thing thank you.
There are other tools that check for the vulnerability not just the one used in the Firefox & Chrome extensions and those extensions are known to throw out a FP.Screenshots were posted with results from 2 other tools that check for the vulnerabilty and both came up good.Sorry you feel that way.
