Websocket Connection Drops in Firefox (HTTP/2)

Introduction

Websocket connections are a crucial aspect of real-time communication on the web, enabling seamless and efficient data exchange between clients and servers. However, in certain scenarios, websocket connections may drop frequently, leading to a poor user experience. In this article, we will delve into the issue of websocket connection drops in Firefox, specifically when using HTTP/2, and explore possible solutions to this problem.

Describe the Bug

The websocket connection drops frequently in Firefox, resulting in a momentary bounce back to the login screen before the connection is re-established. This issue is particularly noticeable when using the Convos application, which relies heavily on websocket connections for real-time communication. The console displays an error message indicating that the connection to the websocket server was interrupted while the page was loading.

The connection to wss://irc.example.com/events was interrupted while the page was loading.

This error message suggests that the issue lies with the websocket connection itself, rather than the underlying network or server configuration. The problem is further exacerbated by the fact that the dropout occurs frequently, sometimes several times a minute.

To Reproduce

To reproduce this issue, follow these steps:

  1. Install Convos: Download and install the Convos application on your system.
  2. Create user account: Create a new user account within the Convos application.
  3. Log in to user account: Log in to the newly created user account.
  4. Wait: Wait for a period of time to observe the websocket connection drop.

Expected Behavior

In an ideal scenario, the Convos application should maintain a stable websocket connection, enabling seamless real-time communication between the client and server. However, in the presence of this bug, the websocket connection drops frequently, resulting in a poor user experience.

Environment

The following environment details are relevant to this issue:

  • OS: Docker (server), macOS 15.4.1 (client)
  • Browser: Firefox 138
  • Version: 8.07
  • Connecting to: libera.chat and oftc.net

Possible Causes

Based on the available information, it appears that the issue is related to the use of HTTP/2 with websockets in Firefox. The fact that disabling the network.http.http2.websockets setting in about:config resolves the issue suggests that there may be a problem with the interaction between HTTP/2 and websockets in Firefox.

Solutions

To resolve this issue, the following solutions can be explored:

  1. Disable HTTP/2: Disabling HTTP/2 in Firefox may resolve the issue, but this may not be a desirable solution, as HTTP/2 provides several benefits, including improved performance and reduced latency.
  2. Upgrade Firefox: Upgrading to the latest version of Firefox may resolve the issue, as newer versions may have addressed the underlying problem.
  3. Use a different browser: If the issue is specific to Firefox, using a different browser, such as Chrome or Safari, may resolve the issue.
  4. Modify the Convos application: Modifying the Convos application to use a different websocket library or configuration may resolve the issue.

Conclusion

In conclusion, the websocket connection drops in Firefox, specifically when using HTTP/2, is a complex that requires further investigation. By understanding the possible causes and exploring different solutions, developers can work towards resolving this issue and providing a better user experience for their users.

Additional Information

  • Firefox Bug Report: A bug report has been filed with Mozilla to investigate this issue further.
  • Convos Issue Tracker: The issue has been reported in the Convos issue tracker, and a patch is being developed to resolve the problem.

Future Work

Future work on this issue may involve:

  • Investigating the underlying cause: Further investigation is needed to determine the root cause of the issue.
  • Developing a patch: A patch is being developed to resolve the issue in the Convos application.
  • Testing and validation: Thorough testing and validation are necessary to ensure that the patch resolves the issue and does not introduce any new problems.

Q&A

Q: What is the cause of the websocket connection drops in Firefox?

A: The exact cause of the websocket connection drops in Firefox is still unknown, but it appears to be related to the interaction between HTTP/2 and websockets in Firefox.

Q: Is this issue specific to Firefox?

A: Yes, this issue is specific to Firefox. Other browsers, such as Chrome and Safari, do not appear to have this issue.

Q: Can I disable HTTP/2 to resolve the issue?

A: Yes, disabling HTTP/2 in Firefox may resolve the issue, but this may not be a desirable solution, as HTTP/2 provides several benefits, including improved performance and reduced latency.

Q: What are the possible solutions to this issue?

A: The possible solutions to this issue include:

  • Disabling HTTP/2 in Firefox
  • Upgrading to the latest version of Firefox
  • Using a different browser, such as Chrome or Safari
  • Modifying the Convos application to use a different websocket library or configuration

Q: Is a patch being developed to resolve this issue?

A: Yes, a patch is being developed to resolve this issue in the Convos application.

Q: How can I report this issue to Mozilla?

A: You can report this issue to Mozilla by filing a bug report on the Mozilla bug tracker.

Q: What is the current status of this issue?

A: The current status of this issue is that it is being investigated by Mozilla and the Convos development team. A patch is being developed to resolve the issue, and testing and validation are ongoing.

Q: Will this issue be resolved in the next version of Firefox?

Q: What are the benefits of using HTTP/2 with websockets?

A: The benefits of using HTTP/2 with websockets include improved performance and reduced latency. HTTP/2 also provides several other benefits, including:

  • Multiplexing: HTTP/2 allows multiple requests to be sent over a single connection, reducing the overhead of establishing new connections.
  • Header compression: HTTP/2 compresses header data, reducing the amount of data that needs to be sent over the network.
  • Server push: HTTP/2 allows servers to push resources to clients, reducing the amount of data that needs to be requested by the client.

Conclusion

In conclusion, the websocket connection drops in Firefox, specifically when using HTTP/2, is a complex issue that requires further investigation. By understanding the possible causes and exploring different solutions, developers can work towards resolving issue and providing a better user experience for their users.
