Details

+++ This bug was initially created as a clone of Bug #1444893 +++ Things might work automagically now when using the devtools panel to capture a profile, but after getting MOZ_PROFILER_STARTUP/SHUTDOWN to work (again), I'm once again stuck with a profile without symbols.
Hey Jan, Can you please share such a profile, on the bug if possible, or somewhere else otherwise?

I wonder if someone could take a look at this, I'm keen to progress it.

If "we" can fix this bug we can look at bug 1506471 which really makes Fennec/GV feel slow on cheap phones where memory pressure kills Fennec a lot and relaunching it is unnecessarily slow.

By "we" I mean "you" of course :) :)

1506471.

This is improved by bug 1505719. If *.so has symbol table, it will be used.

Could you take profiler's JSON gain using the latest of Firefox 66/67?

I think https://github.com/devtools-html/perf.html/pull/1522 may help too, I plan to work on this in the coming weeks.

Re comment 4, I tried https://bugzilla.mozilla.org/show_bug.cgi?id=1506471#c18, don't know if it worked
