Well to my untrained eye they do look like fossilized mud bubbles from a thermal hot spring , perfect breeding ground for life I believe
Here's a similar picture from here on Earth .

It is only a matter of time now.
30 days to burrow and grow
30 days to absorb enough radiation from the Sun for flight
30 days to reach Earth
10 days to devour us all
The Mayans knew containing them on Mars would not be enough.... but how did they know the date?

NASA's long-lived rover Opportunity has returned an image of the Martian surface that is puzzling researchers.
Spherical objects concentrated at an outcrop Opportunity reached last week differ in several ways from iron-rich spherules nicknamed "blueberries" the rover found at its landing site in early 2004 and at many other locations to date.
Opportunity is investigating an outcrop called Kirkwood in the Cape York segment of the western rim of Endeavour Crater. The spheres measure as much as one-eighth of an inch (3 millimeters) in diameter. The analysis is still preliminary, but it indicates that these spheres do not have the high iron content of Martian blueberries.
"This is one of the most extraordinary pictures from the whole mission," said Opportunity's principal investigator, Steve Squyres of Cornell University in Ithaca, N.Y. "Kirkwood is chock full of a dense accumulation of these small spherical objects. Of course, we immediately thought of the blueberries, but this is something different. We never have seen such a dense accumulation of spherules in a rock outcrop on Mars."
Opportunity Science team says that these spherules at Kirkwood do not have the iron-rich composition of the blueberries. They also differ in concentration, distribution and structure. Some of the spherules in this image have been partially eroded away, revealing concentric internal structure. They plan to use the rover for further investigation of these spherules to determine what evidence they can provide about ancient Martian environmental conditions.

From the article they seem to think the popped looking spheres were eroded after fossilization. I see tails on the "tops" of the spheres it looks sortnof like they flowed downwards after they broke the surface of the formation or it's like they seem more a part of the surrounding rock than the blueberries did. It's fascinating

If I'm reading this correctly Methane gas bubbles in sediment can range anywhere between 8.0mm to 0.4mm or maybe smaller , maybe the picture in the OP is of a fossilized sedimentary layer given that its believed that Opportunity is at an ancient Sea bed .
