How/where do I contact Mozilla regarding an exception thrown by Firefox which inaccurately (and arrogantly) claims user behavior as the problem?

Question

I'm trying to voice a complaint regarding THIS user interface ("mozilla support") and the exception message returned to me from Firefox. There's also an ACTUAL browser issue I need to resolve. Here are a few details:
(A) I am unable to use Mozilla Firefox for much at all because it's deciding to attempt secure HTTP connections ("https://..."), seemingly at-will. Not all of the sites I've attempted to reach suggest, require, or support secure HTTP connections.
(B) I cannot install Firebug (at least not without another browser or Fiddler), even when trying to "Confirm Security Exception" repeatedly. I get a 200 OK in my developer tools when requesting "https://addons.cdn.mozilla.net/user-media/addons/1843/firebug-2.0.7-fx.xpi", but then receive a notification stating, "The add-on could not be downloaded because of a connection failure on addons.mozilla.org."
(C) The exception message displayed is infuriating and, in my opinion, unacceptable. It claims, "You have asked Firefox to connect securely..." as it begins describing the exception scenario. I can assure that the only thing about which I was explicit was a request to try the same URL again WITHOUT a secure connection. It sounds really arrogant to say, "Here's how YOU screwed up," when it's definitely more along the lines of, "Here's how THE BROWSER APPLICATION screwed up." If a fresh, default install of Mozilla Firefox can't even download Firebug with a healthy Internet connection (yes, in the context of an intranet but no other browsers are giving me grief), how is that my fault? Even if it is my fault, how dare Mozilla speak to its users in such a manner?
(D) I've tried every proxy setting of which I can think, but that doesn't appear to be the issue.
(E) Too much of my time has been wasted today attempting to relay this information to Mozilla. I was forced to navigate through five or so web pages, answering questions, such that I didn't inconvenience YOU. I've boycotted product lines and/or companies for less, and am trying to "bite my tongue" as best I can, but it shouldn't take an hour to submit a constructive feedback message along the lines of "Your browser isn't working for PRACTICALLY ANYTHING and HERE ARE THE DETAILS." I actually had to accumulate complaints in my mind so I didn't lose them throughout your feedback process (since I don't get to actually provide feedback until somewhere around the fifth step of the process).
Thanks,
Mike

'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
*In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
*In previous Firefox versions, click on the Firefox button at the top left of the Firefox window and click on ''Help'' (or click on ''Help'' in the Menu bar, if you don't have a Firefox button) then click on ''Restart with Add-ons Disabled''.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".

'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
