  • Task manager shows multiple instances of Firefox

    From Wolf K@21:1/5 to All on Tue Mar 16 19:47:56 2021
    Win10 Home 64-bit, 20H2 build 19042.867
    Firefox 68.12.0.esr 64-bit

    On starting Firefox, Taskmanager shows 6 instances (processes) of
    Firefox running, as well as a Node js:server-side script (which
    eventually ends)

    When I open a tab, another instance of Firefox appears. However, the
    number of instances does not depend on the number of tabs I've kept from
    the previous session.

    This is new behaviour, as far as I can recall, previously only one
    instance of Firefox was shown. There doesn't seem to be an impact on performance, and a scan doesn't show any malware.

    What's going on?

    TIA

    Open about:support aka Help > Troubleshooting Information.

    Scroll down to Remote Processes in the Application Basics section.

    Click on the number (it is a link in my 88.0a1 Nightly).

    I see Web Content, Extension, Privileged About, Preallocated and Socket processes. Web Content is using two and the rest only one.

    Thanks, and to Andre z. too

    Your posts confirmed my guess, so no worries.
