Install Random Signature Quotes for Gmail™ from the Chrome Web Store.
Copyright 2013, 2014, 2022, James Mortensen
I made this extension because I couldn't find a tool to let me randomly inject my own user-selected quotes into my email signature. I specifically wanted the quotes to be hand-selected.
Since there wasn't an existing solution, I made one.
To replace the quotes with your own, edit the quotes.js file. You may use HTML markup, but be sure to escape your quotation marks!
The best option for managing the quotes is to use the quote manager. On the right side of the address bar in your Gmail tab, click the page action icon. This pulls up a nice quote editor where you can add quotes, edit quotes, and remove quotes.
The JSON array importer is still available by clicking the "JSON Panel" link in the bottom left of the quote manager. Just be sure to save that data to a backup file, just in case, as the JSON Panel is difficult to use.
