I assume you're referring to the Add-On Compatibility Checker disabling your extensions when you update? To disable Add-On Compatibility Checking you can follow the following steps: 1) Enter "about:config" into the URL bar (no quotes) 2) Right click and create a New Boolean 3) Name it: extensions.checkCompatibility 4) Set it to: False You can now restart Firefox and it will no longer disable your addons. Keep in mind that without the Compatibility Checker Firefox can't guarantee that your extensions will work with the latest versions.
