Mine:

1. Dictionary by Google. I like double-clicking unknown words for an instant definition or translation.

2. Regex search. When ctrl+F just isn't enough.

3. Duplicate Tab Shortcut Key. For those times when I click on a search engine result before pressing ctrl.

For 3, you can also middle click the back button to reopen the search engine tab again.

Here are all the ways I know how to duplicate a tab: - ctrl drag the tab to the side until a downwards arrow appear and then release

- ctrl click the refresh button (any of the navigation buttons really, although they will clone the previous or the next in the history)

- middle click the refresh button

And my favorite: “yt” key combo when using Vimium-ff.

Additionally, it’s useful because I like to keep related tabs next to each other, so I often used these methods to duplicate a tab (or ctrl/middle click on the new tab button to open a blank one next to the current tab), but now I only need to press “t” to open a new blank tab right next to my current one.
