When I start Firefox its extensions (WebExtension process) use ~80 Mb of RAM. After an hour of usage it become ~500 Mb [screenshot 1]. I use only 4 extensions and they use ~30 Mb (as about:performance) says [screenshot 2]. If I manually run garbage collector from about:memory, memory usage decreases to normal ~80 Mb [screenshot 3].

Why GC does not clean memory automatically for me?

Memory reports before and after running GC:
