Prestige doesn't work on Firefox 78, which is default in Debian stable

Hi
When I try to connect to https://prestigemad.com/ with Firefox, I have the message :
Uncaught SyntaxError: expected expression, got '=' index.b332b9df.js:1:409888
It stay blocked on "Loading..." message

Oh hey, thanks for reporting this. I can't seem to reproduce this though. Can you try this out in another browser and see if you get the same error?

[dominiquefournier]

I try to disable all the extensions, but the problem persists on my Firefox 78.15.0esr (64 bits) on Debian (I disable the cache too, check if there is network error).
If I try with Chromium, and the site works well.
Do you have another idea ?

[sharat87]

Ah I see. I didn't take the version number from your comment seriously at first glance, but it looks to be quite old. I am running Firefox 93 myself. I'm thinking that's the problem here. Is that the default version in Debian's repositories? If it is, I should then consider supporting it. Additionally, is it possible to upgrade your Firefox version and try with that to see if the problem goes away?

[dominiquefournier]

Yes it is the Debian Stable "Bullseye" Firefox Version. I can not upgrade the version : my system stay in stable, sorry.

Oh no problem, that's okay. I'll do a test and see what we need to get this running on Firefox 78 at least. Thanks for reporting this. Please consider using Prestige on another browser like Chromium until I get this fixed. Thanks 🙏

Hey @sharat87, I was looking through my GitHub history and came back across this project.

For this - I suspect setting a browserlist as per https://parceljs.org/languages/javascript/#browser-compatibility would fix it. Happy to raise a PR if you'd like?

Hey @MattTennison, thank you for reaching out. I've actually already made that change, see

prestige/frontend/package.json

Lines 15 to 20 in 0b60227

	"browserslist": [
	"last 2 Chrome versions",
	"Firefox >= 78",
	"last 2 Edge versions",
	"last 2 Safari versions"
	],

But it still doesn't seem to work. I started Debian in a VM and opened Firefox 78 that comes shipped with it, and Prestige didn't work in it. I couldn't get back to take a closer look at what's happening there, but that's the status of this. I'd be more than happy to look into a PR to resolve this 😃.
