Login to https://app.netlify.com/login broken on Firefox

Since yesterday.

Visiting Netlify App on Firefox results in a en empty page with errors in the JS console.
Clearing the cache didn’t help.

Firefox: 117.0.1
OS: MacOS 13.5.2

Here’s the errors in the console:

looks like some JS libraries that are loaded contain invalid syntax.

Here’s the console’s output as text:

No one else apart from you seems to be reporting this at the moment and we have Firebox users within the company as well who are not seeing this issue. Are you sure no browser extensions or network issues are causing this?

Hi @hrishikesh,

at some point during the past couple of days the issue disappeared. I assumed that you guys had fixed it on your end.

But I just tried the login page again right now, and the issue is there again

I disabled all extensions using the add-on manager, I cleared the cache and restarted Firefox.

The issue is still there, I get the same errors I posted above.

So yes, I’m quite sure about the browser extensions likely not causing this.

Regarding network issues, what do you have in mind exactly? As you can see from the errors I posted, the JS files are received but they generate an error during parsing. Maybe the CDN is delivering a faulty version of the JS files for some reason? I’m located in Berlin, Germany.

Thanks,
Max

I downloaded one of the offending JS files (graphql.vendor.bundle.js) and loaded it from the REPL console in nodejs. It seems to parse alright.

So somehow the problem seems to be that Firefox is unable to parse those JS files for some reason.

If you have any suggestions or ideas, I’m all ears

Thanks

@hrishikesh Same problem here.

Firefox 116.0
OS: Linux Mint

You also can’t login to Support Forums (with Netlify account) using Firefox, I had to download Chromium to post here.

Sounds more like a Firefox problem then? Not sure how exactly we can fix that. Have you tried different Firefox versions?

I’m on the latest one 117.0.1. Downgrading Firefox appears to be a pain so I haven’t tried it yet. Do you have a way to quickly try out old Firefox versions? In any case, the latest version is the one that counts.

Not being able to log in is a serious problem! You guys should be alarmed but you seem pretty chill about it

Have you tried to reproduce the issue on your end? The fact that all other web applications I use work and only Netlify doesn’t suggests that that the problem is likely with Netlify somehow.

Happening to me too.

Firefox 116
Ubuntu 22.04

I was able to access the site yesterday with no issues. However, today I am experiencing the same issue. Blank screen when attempting to log in. My console shows the same problem. I am on Windows 11, Firefox v117. I have not changed any updates since yesterday when this issue was not happening. I have one extension which I disabled. Tried to clear cache as well, still no result.

Hi, are you having this issue when you try google chrome? i think this is an issue specific with your browser and not netlify. Try clearing your cache and uninstalling extensions.
