Why So Many?

[StevieB]

Why are there so many instances of FF running and ALL at the same time, and at least half of them taking up memory / RAM.

Chrome and Edge don't do this, so why does FF.

It kind of like makes it look like sloppy programming.

See attached picture.

Anyone ?

Having multiple instances of Firefox running simultaneously can be caused by extensions, session restore settings, hardware acceleration, malware, or other factors. To address this issue, try disabling extensions, adjusting session restore settings, disabling hardware acceleration, running a malware scan, updating Firefox, and checking for interference from external applications. If the problem persists, consider creating a new Firefox profile or seeking assistance from the Firefox support community.

Multiple instances of Firefox running simultaneously might occur due to its multi-process architecture, designed for stability. Each process manages different tasks, contributing to memory efficiency and preventing a single crash from affecting the entire browser. While it may appear as high memory usage, this approach enhances performance and isolates issues.
