When it does work, it works really well. I found some scammers will take an image frame from a video in order to fool these sorts of things. They can also flip the image horizontally, and I am not so sure this checks for that. Not a bad app though, certainly easy to use, but most of the time it finds nothing. I think with some work it would be really good.

Helpful info.. (I've been here before because of nonworking TFSC) and my old eyes need help, like a lot of peeps showing up here :)
First, I only use PC Waterfox 64bit 54ver. and I use Thunderbird 32bit 52ver. I have ALL my addon's turned off and not to update including WF and TB. I realize now, That Firefox and Thunderbird will never add some helpful font adjustments for our bad eyes :(
So,...
If you read through the reviews. You'll see some info reviews on how to download and install a non expiring version of TFSC on earlier version of FF, Waterfox, TB. I only wanted to help people because I feel their pain on not being able to see and need help and remember to turn off all updates that includes FF, TB, WF. . I still want to give props to the Author of TFSC. Thx you!

As much as I like the idea of the extension, I find it very suspicious that they failed to properly mention some of the most important information about their privacy, namely "When you use our services, we may automatically log certain information about your use of the services. This information may include how you use the service, your IP address, your search query, the date and time of your query and referrer URL.". A simple line of text here would've made it look more authentic, yet I had to visit their website and go through a few web pages to access this information.
