NextJS not working with Firefox?

[addidotlol]

Hello. About 3 days ago I was code with nextjs and load it up in Firefox. For some reason though, a day later it just refused to load the site. I only noticed that today Chromium is able to load my project up fine. Is anyone able to help or know what might be wrong?

I have

• Cleared cookies
• Cleared data
• Updated Firefox
• Restarted my pc, updated my pc, restarted npm, updated all my packages
• Deleted .next folder

I have no clue what would be happening. This didn't happen before.


1st image is Firefox. Latest version as of writing
2nd image is Chromium. Latest version as of writing.
I am using Arch Linux.

Hello.

Can you provide a reproduction repository so we could investigate it further?

Thank you.

Same Problem over here. Firefox Version 99.0.1. Additionally, I tried deleting all the cache for "localhost". I've got a reproduction repo ready because it contains barely any content other than the defaults. DM me if you are interested because I've got a one commit without the error and the next one with it.

Running on WSL2 Ubuntu 20.04.

Hello! Please share the link to the repository so anyone could investigate 🙂.

Hey! I believe I fixed this via deleting an extension. I had some sort of specific ad block for YouTube which for some reason blocked the NextJS site.

embedvr, good find. I have the same issue and seems to be caused by my "Anti-Adblock Blocker" extension.

Same here, using Firefox 99.0 (64-bit) on Ubuntu 20

I kind of suspect it has something to do with next/image, when there are dozens of them on the page.

Can't provide public repo, sorry. I'll keep investigating.

I would disagree, I did not use a single one of those.

Providing my issue, not sure what is causing it specifically. The cookies().getAll() method on Firefox doesn't return any cookies. Even when they exist in the Local Storage - the issue doesn't appear to happen on Chromium.

My issue seemed related to extensions, however the problems sounds different as for my issue, NextJS just wasn't loading at all.

Note to myself: check for infinite loops next time you are using onLoadingComplete (╯°□°)╯︵ ┻━┻

I have the same issue, I think it's firefox (v126b9 developer edition) related probably to the multicontainers extension, but not 100% sure

• If it stucks, I just have to restart firefox and it works again
• Alternative I can open a private window and it works again

Issue only occurs when running on localhost, not yet sure how to reproduce it.

@RBGAMES101 i still have this regularly with firefox 137. In my case I simply have to close the tab and then the browser. Restart the browser and open the site, then it works again. I don't need to restart next or clear any caches/folders.

i had a similar issue with a freshly created project next 15.5.2. and Firefox Developer Edition version 143.0b2
accessing tit i Firefox that page always hanged with the red error pill in the bottom left (couldn't click it because page hanged)

what seemed to fix the issue for me was removing the React Dev tools extension. after that it works fine
