The update manager in Linux Mint updated libllvm15 and now Brave is completely unusable for me. Is it possible to fix this without using a system backup?
Brave is my primary web browser but every page I visit isn't being rendered correctly at all and some pages are completely broken. I have a system backup from a few days ago but I'd prefer not to have to use it if I can. I think Brave is the only thing that was affected but I think I should try to revert the update if it's possible.
Using Chromium de-googled there's no harm done. Chrome's engine is much faster than Firefox's I'm afraid. It's much easier seen on older hardware, where you can actually feel the difference in speed big time. It happened to me recently on a laptop with only 600 passmark CPU points.
Comparing browsers peformance is not that simple, due to the immense complexity. The only part that's significantly faster in chrome is the JS engine (V8). The CSS engine, for example, is much faster in firefox (try stylebench if you don't believe me) - at least it was last time I tried it. Here are some benchmark results for comparison: https://arewefastyet.com/linux64/benchmarks/overview?numDays=60
Also, firefox uses much less resources (CPU/Ram), so it consumes less battery and doesn't slow down other programs as much while it's running in the background.
