Some nice tips and how to's. My favorite:
QuoteSet up Reddit as a search engine
https://vivaldi.com/blog/browse-reddit-with-vivaldi/
I'm a loyal/staunch FF user, but if I had to ditch I'd use Vivaldi. Only qualm I've ever had with them is they used to cloak/be the Chrome user agent and it was impossible to differentiate them even though they weren't chrome.
Their reddit search is a good shout, seems to be a popular trick for product reviews especially, to avoid the inevitable top 10 Amazon/G results.
I like how easy it is to add different search engines to Vivaldi. After so many posts and articles about appending "Reddit" on to the end of search engine queries, I'm just glad somebody at Vivaldi's blog suggested that we add Reddit search directly to the browser.
