After some years of stability, FoxyProxy has been updated to support Manifest Version 3 which is required by Chrome in order for extensions to be compatible with Chrome in 2024. We took advantage of this forced update to implement many feature requests and other changes that were requested over the years.
FoxyProxy has been owned and developed consistently by the same team since 2006.
The repository has the source code for version 8.0+ for *Firefox*, *Chrome*, and other Chromium-based browsers like *Chromium*, *Brave* and *Edge*. Source code for [older versions](https://github.com/foxyproxy/firefox-extension).
- **downloads**: Required to export the extension settings to a file. Users can import that file to other Chrome/Firefox instances, or share it with colleagues, in order to keep the same settings. It can also be backed up and used later.
- **proxy**: The core function of the extension is to allow users to set the proxy server used by the browser.
- **storage**: Required to store proxy server settings (hostname, port, username, and which proxy server is enabled by the user).
- **tabs**: Required so that users can set separate proxies to use per tab. It is also needed for "QuickAdd" to quickly add a URL pattern that applies to the current/active tab. It is also used to open a URL to `getfoxyproxy.org` where there is online help.
- **webRequest**: Required to authenticate with proxy servers via webRequest.onAuthRequired
- **webRequestAuthProvider**: Required to authenticate with proxies servers via webRequest.onAuthRequired
- **browsingData**: Required so the extension can delete cookies, indexedDB, and localStorage when requested by the user on the Options page (*Delete Browsing Data* button)
- **privacy**: Required so the extension can call `browser.privacy.network.webRTCIPHandlingPolicy` to turn on/off webRTC in Chrome (*Limit WebRTC* checkbox in Options page)
- **host permission**: `"<all_urls>"` permissions is required in order to supply credentials for [Proxy authorization](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/webRequest/onAuthRequired#proxy_authorization)
The crypto library was already included in [FoxyProxy 3.x](https://github.com/foxyproxy/Foxyproxy_Chrome/blob/f1bca1c50dfa30908c79a9ea477f31eda2abacf4/app/scripts/stored-credentials.js#L4) to encrypt user credentials. It is needed to migrate encrypted settings from the old version (which had no updates for many years, as you mentioned) to 2023. It is not used to encrypt anything; only to decrypt old data when upgrading from version 3.x -> 8.x.
Using Firefox and you've lost all FoxyProxy settings?
FoxyProxy Basic 8.0 was first released in Sep 2023 as a trial run since it had fewer users (26k on Chrome & Firefox).
We waited for 2 months for any feedback & bug reports before releasing FoxyProxy Standard.
Unfortunately, we didn't get any bug report about the data migration sync issue, otherwise we would have fixed it before releasing the standard version.
FoxyProxy 8.2 went online on Dec 6th.
Due to a bug in version 8.2, previous settings of some users were not migrated after the upgrade.
Versions 8.3-8.6 created with fixes for the bugs immediately, but due to the AMO approval waiting time, version 8.6 came online on Dec 12th.
Previous settings were not deleted and are recoverable. The following options are available if FoxyProxy updated from 7.* and you have encountered the update bug.

From [this comment](https://github.com/foxyproxy/browser-extension/issues/45#issuecomment-1838719332):
### Look for old data
1. Go to the FoxyProxy Options page
2. Open the Dev Tools (F12)
3. Go to the Console tab
4. Type the following and hit ENTER
### With Sync
```js
browser.storage.sync.get().then(console.log)
```
If above has some data, then in the Console tab, type the following and hit ENTER
```js
browser.storage.sync.get().then(pref => {
const data = JSON.stringify(pref, null, 2);
const blob = new Blob([data], {type: 'application/json'});
browser.downloads.download({
url: URL.createObjectURL(blob),
filename: 'FoxyProxy_sync.json',
saveAs: true,
conflictAction: 'uniquify'
})
.catch(() => {});
});
```
### Without Sync
```js
browser.storage.local.get().then(console.log)
```
If above has some data, then in the Console tab, type the following and hit ENTER
```js
browser.storage.local.get().then(pref => {
const data = JSON.stringify(pref, null, 2);
const blob = new Blob([data], {type: 'application/json'});
browser.downloads.download({
url: URL.createObjectURL(blob),
filename: 'FoxyProxy_local.json',
saveAs: true,
conflictAction: 'uniquify'
})
.catch(() => {});
});
```
### Import data
1. Go to **Import Tab -> Import from older versions**

## 📱 Firefox for Android
Firefox for Android ignored disabling `extensions.update.enabled` (due to a [bug](https://bugzilla.mozilla.org/show_bug.cgi?id=1872169)). Therefore, installation of an older version from AMO will get updated. The bug is fixed in Firefox 123.
