But they appears even if I disable all modules. Based on other responses, we know what "web content" in Top constitutes. I wish they would have unique names instead of just "web content." Would make things easier. Someone said your slowness problems is caused by library, etc. incompatibility. I was wondering . . . You said you're running Firefox 62.0.3, IIRC. Did you install this from Sid's repo or download directly from Mozilla? I downloaded Firefox Quantum 62.0.3 from Mozilla (tar.gz file) and installed it manually. Quantum isn't in the Stretch repo. I just copied the entire firefox directory to /opt. (FYI: I run only Openbox with a single LXPanel with menu.) If you haven't done this, maybe, give it a try. The binary has to be very generic as it's designed to run on various versions of Linux not just Debian. Maybe, it will be more compatible. B
