Myth: uBlock consumes several or several dozen GB of RAM

I've seen a couple of instances of people claiming uBlock Origin (uBO) eats several or several dozen gigabytes of RAM.
Examples:

• Ublock origin uses 26.6gb of memory on firefox #994
• Using 24+Gb of virtual memory on Firefox/Ubuntu 20.04 #1532
• Cause memory leak on Firefox 107 #2401
• WebExtension process can take 3GB as per profiling. 1.5GB with default settings. #3198

These are just bogus / virtual memory readings, not real RAM usage.
All technical explanations are contained in the linked issues above.

Hence there is no point in spamming the issue tracker by creating new duplicates over and over, discussion and sharing opinions should be continued in already existing threads, new threads will be labeled as invalid or duplicate and closed.
