Block downloads from specific sites
There's a site I use frequently that downloads .htm files to my computer every time I open it in a new window. The site does not have a settings page to turn this feature off. It also functions exactly the same once the file is deleted, and it only recently started doing this. I trust that the files are not malicious, but I also find it annoying to manually delete them every single time.
Is there a way within Firefox to block specific sites from downloading content?

I have no idea what those files are, but one thing you could do is turn off auto-saving so you can more quickly reject the download. This setting is on the Settings page, below the "Applications" box. I'm repurposing this image, so skip over the first page and look at the lower part:
Did you check the content of those files assuming that this aren't zero byte files ?

They are zero-byte files, actually.
Some users have reported getting 0 byte files that are described on the downloads list as moz-safe-about files. I'm not sure what triggers those. It's possibly related to pages or ad servers trying to access built-in about: pages and Firefox providing a fake response.
Getting zero-byte .htm files can be caused by downloading a file over an insecure HTTP link from a secure HTTPS page (i.e. mixed content is on the page) or by Firefox sending a HTTP background request in HTTPS-Only mode and "dom.block_download_insecure = true" You can try:
- about:config => dom.security.https_only_mode_send_http_background_request => false
