This browser extension adds a timer to the lichess.org puzzle trainer. Unlike other timers, this one prevents you from making a move until the timer expires to try to help you force yourself into actually calculating all variations. It also has a traditional blitz mode if you prefer.

Once installed it should add the timer above the move list on puzzle pages. You can disable/enable it with the toggle to the left of the timer, and change settings by clicking on the gear icon to the right of the timer.

From the settings dialog, you can switch modes:

Thinking mode - prevents you from making a move until the timer reaches zero to encourage you to calculate all variations before just making the first move you see.
Blitz mode - you must move before the timer reaches zero. Or else. For more fun, you can enable "auto fail" so that if you don't complete the puzzle on time, the extension will click "view the solution" automatically and you'll fail the puzzle. If you like Puzzle Storm but wish you could lose real puzzle rating points, try this mode with 10 seconds and "Jump to next puzzle immediately" option enabled.
