Too many spawn child processess and browser freeze
Firefox spawn too many child processess, with cause the browser to freeze.
Proposed solution:
Reduce to absolute minimum the spawn child processess. The value should be set according to the device performance and additionally show allow the user to set manually the limits.
Example: 1 (maximal 3) child process per tab/window

FISSION: The links are sites explaining the Firefox's Project Fission. This is the reason for the processes you see in task manager.
You can turn fission off by setting it to false on the about:config page. see screenshot Here is more info. https://www.ghacks.net/2016/02/15/change-how-many-processes-multi-process-firefox-uses/

The change didn't worked and even after changing the config value to a smaller number, firefox was independantly spawning a loot of child processess (minimum 30), even if there was opened only the dashboard or a about:blank page.
Any attempt's of clossing them thru a process manager were failing because them were restarted (restored) short after killing.
Prefered solution:
When starting Firefox, there should be created few "container" child-processess (one for each kind) in with remaining child processes would be spawned. The example main "containers":
- for extensions
- for browser utilities
- for content
In the content container, each page should have own sub-container. This way, It would be able to close it separatelly (for example if it stop ro response), without need to close firefox or kill it's process.
Additionally:
- there should exist in "about:config" options to precise control the processess
- garbage collectors, etc. should do anything instead of pretending doing it

What do you have set here. https://support.mozilla.org/en-US/kb/performance-settings The answer here may also help. https://support.mozilla.org/mk/questions/1412530
After unchecking the "performance" option, the next options to control the efficiency not always appear.
Additionally, changing of some performance settings in the "about:config" seem to have no effect
