We agree on browsers, probably for the same reasons. Along with an an assortment of extensions, I use HTTPS Everywhere, that either forces an HTTPS connection or blocks it. I find it will usually make a secure connection even if the URL is HTTP. For some reason its common for secure sites to connect initially through HTTP, I have no idea why but I come across it often. As a fallback, I have the no-script to limit problems. It's worth noting that FF has an HTTPS only mode that you can enable in settings if you don't want to run the extension I mentioned.
I personally, with HTTPS only enabled, wouldn't hesitate to open your HTTP link especially if you trust the source.
If your not familiar with this browser test,

If you like digital Irony this is worth a read also.
