I'm thinking the reasons might have something to do with:
- Lower memory usage compared to Chrome [1]
- Increasingly more of it being written in a fast and memory-safe language, Rust [2]
- Not belonging to a for-profit company [3]
Would also be nice to know what plans Mozilla has for Firefox in the longer term. Once Firefox becomes a near Chrome clone written in Rust, what comes next?[1] - https://blog.mozilla.org/firefox/firefox-uses-less-memory-chrome-edge-safari/
