How to find which extension has a memory leak?

Hello! I have a few addons(extensions) and I think that one of them has a memory leak. I can say that because in the "about:memory" tab the WebExtension process can eat all of my free memory (see the attached screenshot). And after that Firefox usually crashes. Example crash report: https://crash-stats.mozilla.com/report/index/97e8dba8-c749-42d3-bfb2-865fd0180307

Is it possible to find out which addon is responsible for huge memory allocations? For example, Chrome has very good "Task Manager" window where you can see "Memory footprint" for each extension and tab. Does the Firefox has the similar functionality somewhere?
