Please import your old FoxyProxy settings using the Import button!

Firefox 57+ is significantly different than previous Firefox versions. I was forced to re-write 10 years of mature FoxyProxy code from scratch. There are many missing features, and in almost all cases that is due to Firefox 57+ limitations or bugs (for example, custom-colored toolbar icons). The UI also had to change; I could no longer make FoxyProxy look like a native application. It now looks more like a traditional web site.

I understand your frustration. Please refrain from attacking me because there is nothing I can do to change Mozilla's decisions. Thank you for using my labor of love. -- Eric H. Jung, November 2017

Version 3.6.1 946.8 KiB Works with Firefox 3.1b3 - 51.0, SeaMonkey 2.0a - 2.36, Thunderbird 3.0a1pre - 45.0

* SSL/HTTPS proxies now supported! optionally with authentication). SSL/HTTPS proxies encrypt traffic between you and the proxy server. Do not use unless you know for certain that your proxy server supports this -- https://bugzilla.mozilla.org/show_bug.cgi?id=378637. Note that FoxyProxy proxy servers (https://getfoxyproxy.org/order) support this on port 4443
* Authentication for SOCKS proxies now supported. Previously, we supported SOCKS proxies but not with authentication -- https://bugzilla.mozilla.org/show_bug.cgi?id=122752. Thanks for help from Felix Shao.
* Fixes for https://bugzilla.mozilla.org/show_bug.cgi?id=1308817 -- HTTP basic auth goes directly to 401 error page when foxyproxy is enabled
* Fixes for https://bugzilla.mozilla.org/show_bug.cgi?id=1322293 -- FoxyProxy doesn't work in Nightly, due to use of no-longer-supported "for each" statement
* Prevent cluttering the about:neterror?e=proxyConnectFailure page
* Change references of the word 'host' to 'server'. It appears some people do not know what is meant by 'host', and the term does seem dated.http://www.ghacks.net/2015/06/19/how-to-disable-the-firefox-40-add-on-signing-requirement/
* Removed some dead links (pattern sharing, proxy sharing, etc)
https://bugzilla.mozilla.org/show_bug.cgi?id=1083458 -- Remove SpiderMonkey support for expression closures (shorthand function syntax)
* Minor code changes to avoid "JavaScript strict warnings" (components/foxyproxy.js, line 1268: ReferenceError: reference to undefined property "_maxSize")
* Strip http:// and https:// when user prepends it to proxy server names
* There was no 3.6 release. This release is numbered 3.6.1 because 3.6 was only partially uploaded to addons.mozilla.org. There is was no apparent, fast way to delete 3.6 and so AMO prevented a "new" 3.6 XPI from being uploaded. https://discourse.mozilla-community.org/t/new-version-of-existing-addon-submitted-partially-now-cannot-complete/13124
