Last 2 that I have:

Hover Zoom+ lets you mouseover an image & if it's linked to an image or the image is bigger, it will show that image.

Weather is self-explanatory :D

OpenList

https://chrome.google.com/webstore/d...dcngbgnl?hl=en

Opens a simple text edit window with all the tabs listed one per line as URLs.

Means I can capture all my open tabs as URLs and cut-and-paste them to a spreadsheet.

more importantly, I can do the reverse.

Take a list of URLs from a spreadsheet or text file and cut and paste into that box then all the tabs open for me.

Use this many times every day.

It's not an extension, but this online calculator is helpful for me.
Calculating "thumb-sizes" in a table.
