Set your current tab as an **active tab**. The active tab here means a tab where the block requires a tab like a take screenshot block will execute.

For instance, when you run a JS code on a current website or make a screenshot, you can use the active tab before connecting others (like the *take a screenshot* or *javascript code* block).
