Functional, but ends up removing Way More image results than just pinterest images (though thats likely an issue with google)
Plus, ive moved off of using google except for very specific searches that other search engines cant find and this isnt built for those.

It doesn't work for Duckduckgo but I added stars just for existing. F**ck the cancer that is pinterest.

Please add a function that get called after page loaded that remove the -site:pinterest.* from the search container

Had been working perfectly until I needed to do a full reinstall of windows 10. Now, for some reason, -pinterest is no longer added when doing image searches. Hope a solution is available.

Uninstalled and reinstalled. Cleared cache. Closed Firefox and reopened. Still not adding -site:pinterest.* to image searches. As mentioned, it worked perfectly before I reinstalled both Windows 10 and Firefox. Chrome is working fine again though.
