Looks like I have memory leakage
I use 56.0.1 (64-bit). For the sake of this question, I just opened FF, did not use it and I have 2 open tabs. The extension 'about:addons-memory' claims I use a total of 69.24 MB. The extension 'Tab Memory Usage' claims I use 10.4+30.3=40.7 MB. The task manager claims Firefox uses over 400 MB. Once I start working with FF, memory usage will fly up the roof (according to the task manager, not according to the 2 abovementioned extensions) and performance will drop accordingly.
