I have found a 3rd party extension that claims to facilitate this (0) but still feel uncomfortable to use this for privacy reasons.

Although using Firefox increasingly means a worse experience, including:
* infinite loop of Cloudflare verification * inferior performance compared to Chrome (page loading, large page scrolling) * subtle bugs (e.g. audio handling) * WebUSB support
I have personally run into all of them. Some are under Firefox's control but others are not. I do still use Firefox for most websites unless it's technically not possible, but unfortunately the exception is happening more and more.
The first two are likely due to extensions rather than the core Firefox. I find at least as many cases where it’s faster, and it usually uses less memory. The third one has high variability - I’ve reported enough bugs against all of the major browsers not to trust any of them but these days there are a lot of web developers who only test on Chrome and half of the time I find what appears to be a bug in Safari or Firefox it’s really an unnecessary reliance on something Chrome specific.
