I cannot enable SSL 3.0 (SSLv3) in Firefox

So in old versions of Firefox you could go into about:config and change values (i.e. security.tls.version.min) to enable SSLv3. I am currently running Firefox 39.0 and I can no longer do that.

Here is the problem: I am a network specialist and I have to log into various network appliances on a regular basis. Many of these have old firmware that I am upgrading and use SSLv3 in their web interface. I need to be able to access these devices even if Firefox doesn't want me to. Other browsers are doing the same thing.

If there is a way, please let me know how I can enable SSLv3 functionality in Firefox.

Thanks,

hi, you could set-up an older portable version of firefox from http://portableapps.com/apps/internet/firefox-portable-esr (those are 3rd-party builds and not provided by mozilla directly). you can configure it not to update and reallow ssl3 for example and just use it for the purpose of accessing those network devices...

Hi, yes I hear you. I've been using an old version of IE on one workstation and I actually downloaded Netscape Navigator (for some other archaic functions) on another. My problem is that, while I agree it should be disabled by default, Firefox shouldn't be telling me I can't use a security protocol if I want to.

I'm not happy about this development decision.
