The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.
If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.
Currently, you have:
(A) Firefox's Safe Mode, which disables all extensions and requires a restart, or
(B) Firefox's Add-ons page, Extensions panel, which allows you to disable an individual extension, or
(C) Features provided by individual add-ons to enable/disable various of their functionality (via toolbar button or right-click menu, etc.).
It sounds as though you would like a faster way to do "B"?
Note that you can use a separate profile that doesn't have extensions installed.
You can add -no-remote to the command line to open another Firefox instance with its own profile and run multiple Firefox instances simultaneously.
