# Browser Extension Version 16.5.0

## Features

* **BE-4537**: Handling of Web socket requests when MV3 browser extension service worker has been terminated
* **BE-4802**: New Safari extension \[[User Guide](/user-guides/jp/browser-extensions/keeperfill-for-safari.md)]
* **BE-4536**: Bootstrapping for MV3: When the service worker is stopped, all memory is lost. The next time the extension boots up, based on what the user's last action was, it grabs what it needs from physical storage, processes that, puts it into memory, then does perform the user's last action if there was one.

## Bug Fixes

* **BE-4749**: Login to Upwork.com is clicking the wrong button
* **BE-4938**: Firefox using too much memory
* **BE-4979**: Keeper throws errors on mapfreconnect.com
* **BE-4977**: When you disconnect from the network and reconnect, the extension shows logged in; however, it prompts for 2FA and can send SMS 2FA incorrectly.
* **BE-4983**: Form filling is broken for V2 (general) custom fields
* **BE-4990**: Autofill broken on squareup.com
* **BE-4956**: Based on customer feedback, we removed the "prompt to login" on page loads.
* **BE-4988**: When the extension fills into an http / insecure site, the extension will ask the user through a window popup if the user would like to continue to fill the inputs because the connection is insecure. Clicking "OK" doesn't fill the contents or close the window and clicking cancel doesn't close the window.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.keeper.io/release-notes/jp/browser/browser-extension/older/browser-extension-version-16.5.0.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
