Closed issue by noarchwastaken on void-packages repository

https://github.com/void-linux/void-packages/issues/39652

Description:
### Is this a new report?

Yes

### System Info

Void 5.19.10_1 x86_64 GenuineIntel uptodate rrmFFFFFFFFFFFFFF

### Package(s) Affected

firefox-105.0.1_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

The `firefox` package should run about as fast as the one from mozilla.org.

### Actual behaviour

I tested the two different builds of Firefox:
- With entirely new profiles
- With my daily profile that has anti-fingerprinting tweaks and loaded with addons

And the package from Void repository runs consistently slower than the "Official" release, both in synthetic benchmarks:

and in subjective terms, such as pages loading slower.

### Steps to reproduce

1. Install Firefox from the `firefox` package as well as from https://www.mozilla.org/en-US/firefox/all/#product-desktop-release
2. Browse the web and pay attention to performance differences
