Details
What were you doing?
- Open the netmonitor of the devtools and perform a request.
- Click on a request to open the side bar, then close the side bar. Repeat the action of opening and closing the side bar for a few times.
What happened?
Notice the waterfall column gets gradually smaller every time the side bar is opened and closed, while other columns gets bigger. Eventually, the width of the waterfall column can get so small that it is barely visible. This can also be observed in the preference devtools.netmonitor.columnsData (which controls the widths of all the netmonitor columns):
Default value:
[{"name":"status","minWidth":30,"width":5}, {"name":"method","minWidth":30,"width":5}, {"name":"domain","minWidth":30,"width":10}, {"name":"file","minWidth":30,"width":25}, {"name":"url","minWidth":30,"width":25}, {"name":"cause","minWidth":30,"width":10},{"name":"type","minWidth":30,"width":5},{"name":"transferred","minWidth":30,"width":10},{"name":"contentSize","minWidth":30,"width":5},{"name":"waterfall","minWidth":150,"width":25}]
After opening and closing the side bar once:
[{"name":"status","minWidth":30,"width":5.34},{"name":"method","minWidth":30,"width":5.34},{"name":"domain","minWidth":30,"width":10.66},{"name":"file","minWidth":30,"width":26.67},{"name":"url","minWidth":30,"width":25},{"name":"cause","minWidth":30,"width":10.66},{"name":"type","minWidth":30,"width":5.34},{"name":"transferred","minWidth":30,"width":10.66},{"name":"contentSize","minWidth":30,"width":5.34},{"name":"waterfall","minWidth":150,"width":20}]
After opening and closing the sidebar another time:
[{"name":"status","minWidth":30,"width":5.56},{"name":"method","minWidth":30,"width":5.56},{"name":"domain","minWidth":30,"width":11.1},{"name":"file","minWidth":30,"width":27.78},{"name":"url","minWidth":30,"width":25},{"name":"cause","minWidth":30,"width":11.1},{"name":"type","minWidth":30,"width":5.56},{"name":"transferred","minWidth":30,"width":11.1},{"name":"contentSize","minWidth":30,"width":5.56},{"name":"waterfall","minWidth":150,"width":16.67}]
What should have happened?
The width of all the columns should be preserved even after opening and closing the side bar.
This could be due to Bug 1582719, which hides the waterfall column when the side bar is opened.

Thanks for the report!
This is DUP of Bug 1617834
This could be due to Bug 1582719, which hides the waterfall column when the side bar is opened.
Would you be willing to try to revert that patch?
I was looking at this issue in Bug 1617834 and couldn't figure out what the problem is.
Knowing the regression would be great help!
I am closing this report so, please post any new comments into Bug 1617834
