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.
uBlock Origin - An efficient blocker for Chromium and Firefox. Fast and lean.
