Thanks for flagging, we'll look into this.

I'm experiencing the same problem with slightly different symptoms.

Test system: Firefox 66.0.2 on Ubuntu 18.04.2 LTS
Using Chromium (build 73.0.3683.86) the below steps do not reproduce the problem.

To reproduce:

1. Open an article on dev.to
2. Follow a link or image that navigates away from dev.to
3. Use browser back to return to article
   -> "It looks like you're offline" screen appears.

Simple reloading does nothing, however Ctrl + F5 resolves the issue.

I've added additional logging to Service Worker. If anybody ever come across an aggressive offline page, please share the logging from your browser console.

Hi! :)
I can still reproduce the behavior I described above with Firefox 67.0.1 on Ubuntu 18.04.2 LTS.

I went over to dev.to and opened the article How to Be Great? Just Be Good, Repeatably , clicked on the link in the first line, navigating to the authors blog.
Hit browser back to go back to the dev.to article and got the "You're offline" page.

I have attached the console output starting from the time I first visited dev.to: console.log

The relevant part of the log is probably this, right after I had hit browser back:

Navigated to https://dev.to/stephsmithio/how-to-be-great-just-be-good-repeatably-bk5
TypeError: NetworkError when attempting to fetch resource. serviceworker.js:1:3040

Thanks for quick report @danielw93 . Are you using privacy badger or uMatrix by any chance? Is this reproducible in incognito?

[d4l-w4r]

@maestromac Good call!
It seems that Privacy Badger was indeed the problem. It showed dev.to as a potential tracker and had completely blocked the domain 🤦
After manually reenabling dev.to I can no longer reproduce the reported behavior.

[maestromac]

Yeah, Service Worker is still a bit wonky and is false positive to extensions like Privacy Badger. Thanks for checking!

Are you still experiencing this issue @stereobooster ?

[stereobooster]

Hey @maestromac. No it was one time thing if we talk about offline screen issue.

[maestromac]

Alrighty, I'm assuming this issue is resolved. Please let me know if otherwise!!
