The main difference between Chrome and Firefox extensions is that Chrome uses a callback-based API while Firefox's is based on promises. Other than that they're functionally the same aside from some differences in the manifest and the namespace (Chrome uses `chrome` while Firefox uses `browser`). I think Firefox has some backwards compatibility with the callback interface for easier porting but I haven't tried.

There's a nice polyfill by Mozilla so you can use their promise interface in Chrome but it was missing some important apis last I checked (sessions and optional permissions). https://github.com/mozilla/webextension-polyfill

Firefox: TabSearch: https://addons.mozilla.org/en-US/firefox/addon/tab_search/

Fuzzy search for tabs + keyboard controls for tab management. (I made this, hope it's alright that I'm advertising)

Octotree: https://addons.mozilla.org/en-US/firefox/addon/octotree/

Adds a tree-style panel to the side of every GitHub repo, makes it easy to browse and skim source code.
