Use the Zapier Push browser extension to save a website for later. Just trigger the zap and the URL of the currently active tab will be sent to Zapier.
First you need to install the Zapier Push browser extension, to be able to trigger this zap directly from your browser.
When the zap is live, and when you trigger it via the Push extension, one of the fields received in Zapier is the URL of the currently active browser tab.
In the next step, we then email ourselves with that URL. But you can do something else with it, like save it to a Google Sheet, to Pocket or another bookmarking app, or even post it to a Slack channel.
