Works as described. What else would you want? Nothing.

works well on zen browser

Works as expected and is exactly all I was after. I'm also using Zen Browser.

Need-it as a specific research, good implementation on Zen Browser

Works perfectly well and seems to not consume any user data (unlike perplexity itself tho). If you don't know, you can set it to default search engine in ff settings > search

Same thing as adding a bookmark to https://www.perplexity.ai/search/new?q=%s and setting @perplexity as keyword. I preferred "pp".

Does what it says in the name. It's Perplexity in the Omnibox It works like it should and doesn't do anything unexpected.
Great work 8columns :)

Great extention. Adds a search bang, makes my workflow much faster. Since it just redirects you to perplexity, if you're logged in, it will use your settings. Overall very impressed.
I would love to see an option to choose search filter right there in the search bar, not sure if this is possible.
