1659609 - url does not work on first attempt

Status: NEW

(Core :: DOM: Service Workers, defect, P2)

Description

[Nate]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:79.0) Gecko/20100101 Firefox/79.0

Steps to reproduce:

Typed "outlook.com" in address bar and then hit Enter key.

Actual results:

Nothing happened.

Expected results:

Firefox should have gone to https://outlook.live.com/mail/0/inbox (the automatic Microsoft redirect). Behavior started a couple weeks ago. It happens every day and with other manually-typed urls that used to work.

Forgot to mention that when I type the url into the address bar a second time it always works. It's the first time that produces no action.

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

I can reproduce the issue if login status of the site was remembered.

I’ve been experiencing this bug a lot at least a month now. I have a self-hosted Discourse forum (not publicly accessible) that is affected. There’s nothing in the console. The bug only manifests intermittently, but when it does, I sometimes have to restart the browser to make the page load again. I think new tabs are affected more, but it also happens in existing tabs (that already have pages loaded).

The Discourse Service Worker script is based on Google Workbox. It does not rely on external script files. It is used to intercept HTTP requests and to display notifications.

I am having this problem consistently if the first URL I open after starting Firefox is mail.google.com. It happens only the first time after Firefox is started, not in a new window or tab, but after a restart of Firefox. I can even open many tabs and windows after the restart and the first tab in which I navigate somewhere, if I navigate to mail.google.com, it fails. After that, in that tab and in all others it works.
Other URL mostly work also the first time.

I have these errors in the console, but I have them as soon as Firefox starts, before clicking anything, I don't know whether they are relevant:

I have the problem both in Linux Mint and in Windows 10.

Interestingly enough, if I open the network monitor, it shows one request to google with Status: blocked. This could be the key.
