Firefox first load

[olivier-voutat]

Describe the bug

We migrated our application from cra to Vite recently.
When we launch our application in debug mode using Firefox, it takes a long time to load. Arround 5 seconds.
In other browsers we don't have this problem.
In firefox, accessing the deployed version, we don't have this problem too.

I am also experiencing a similar issue on a MAC M2 air 16gb / 512 gb SSD macOS Sequoia 15.1 and I am running Firefox v132.0.1. When I reload my react project a couple of times, the project will stop rendering. So I have to refresh the local dev server and reload the page again. It works just fine on Safari and Chrome.

Is there an update on this? Dev via firefox is borderline unusable for me. The dev server has to be stopped and started again frequently, and a page refresh takes 40 seconds in firefox compared to 7 in chrome.
