I use a pop-up dictionary extension called Yomitan which has an incredibly useful search feature that allows you not only to look up individual words, but entire phrases, which lets you very quickly break them down without needing to look up each word one-by-one.
The search feature can be opened in a tab for convenient usage, but it would be even more convenient to just add Yomitan as a proper search engine in Firefox. Then I could set up an incredibly easy and fast way to paste text then start breaking it down from anywhere.
However, Firefox does not allow this because it does not start with http or https. I don't know if there's legitimate reasoning for this, like a security feature, but for my usage it's quite limiting. Please open this up so I can use this feature and make Firefox the ultimate browser for learning languages.
