1Password Firefox Extension Kills Performance

Question

Using Firefox 90.0.2 (the latest version), with a fresh profile, browsing the web is noticeably slower when the 1Password extension is enabled.  To quantify this, I tried running a browser benchmark using the Speedometer 2.0 test: https://browserbench.org/Speedometer2.0/

In a fresh install of Firefox 90.0.2, on a recent Intel Macbook pro, Firefox receives a score of 94.2.  After enabling the 1Password Addon, the test takes a minute longer to complete, and the score falls to 70.5.  Disable the 1Password addon in Firefox, and the score will return to 94.2.

This is consistently reproducible for me by disabling and re-enabling the 1Password extension.

Hardware: Late 2019 Intel Macbook Pro 16", 16gb Memory, 2.6Ghz 6-core
Browser: Firefox 90.0.2
OS: Mac OSX 11.5 
1Password Version: 7.8.6
1Password Firefox Addon Version: 2.0.5

1Password Version: 7.8.6
Extension Version: 2.0.5
OS Version: OSX 11.5

I can confirm a similar decrease of approximately 20 points in this benchmark in both Chrome and Edge on Windows 10.

While this is far better than the nearly 75 point loss seen from LastPass, it's still significantly worse than Bitwarden which only sees a decrease of 2-3 points.

Functionality and use-friendliness of 1password is definitely better than Bitwarden but it would be nice to see that performance gap closed up.
