Firefox cannot establish the websocket connection but other browsers and firefox private browsing can. about nicegui HOT 8 OPEN

restarting firefox in "troubleshooting mode" also seems to fix the issue (from the hamburger menu -> help -> troubleshooting mode

from nicegui.

the working browser shown above is Edge

I suspect it has something to do with the browser cache.

Can anyone else reproduce this issue?

from nicegui.

it may require making small changes to the code (add / remove the button) between restarts to trigger the firefox failure

from nicegui.

Firefox works for me and my project. Probably one of the extensions interferes since the problem doesn't exist in private mode?.. 🤔
I start the app using Debug in PyCharm IDE.
If you suspect the cache is the issue, does reloading the page with Ctrl+F5 (bypassing the cache) help?

from nicegui.

I was not able to repeat the issue after re-installing the Adblock Ultimate Extension. I think I was running a multi-year old version of the extension.

from nicegui.

nevermind the issue is back.

Issue persists after:

1. Removing all extensions
2. ctrl + F5
