Firefox needs to go with a one locked-down process per tab model. There is no excuse these days for a single tab crash to kill off substantial portions of the browser. Moreover, there is no excuse for a tab compromise to allow access to other tabs' memory.

I use Chromium because it has both a safer and more reliable design and implementation. If web browsers were OS's, Firefox would be Mac OS 9. If Mozilla wants to understand why they're losing market share, they should try and understand why no one builds OS's like that anymore.

That's in the latest version.

It's an inefficient use of computing resources, but necessary for security, mostly because of Spectre.
