Relative paths seem to break the plugin:
A test case can be easily created by creating a folder and placing an HTML file with an object pointing to an SVG file in the parent directory, "../foldername/filename.svg".
This is a separate issue from Proxy not supported and HTTP authentication not supported items, as a test was made using a local web server without authentication.
Access denied page is displayed without any authentication prompt displayed.
While trying to open a simple example, Croczilla SVG Tetris, a message similar to the following screenshot is displayed:
Given my network environment, this hints towards the plug-in doesn't support proxy. This is a requirement for a successful enterprise deployement, as most companies setup one for bandwidth optimization and/or content triaging.
Software environment in use:
When loading the ActiveX control, a message similar to the following image is displayed:
Not filling out the information may cause some discomfort to less technical users, as this has a bit of malware flavor. "Savarese Software Research Corporation" would make sense, at least until/if this interesting piece of software is embraced by the Mozilla Corporation.
When issuing a command line like:
regsvr32 "%ProgramFiles%\Savarese Software Research Corporation\Ssrc SVG Plugin v1.9.1b4\mozctlx.dll"An error similar to the following image is displayed:

Currently the context menu contains the following entries:
The properties dialog displays no interesting information, as stated in the following screenshot:
This is somehow related with the Context menu items not effective.
Using a ".txt" extension for the plug-in download and not providing any information about it makes it sound like the download is broken, specially for less technical users (I must confess I was a bit surprised).
I'd suggest something like "Use your browser's 'Save As...' or equivalent option to download the file(s) and remove the (fake) '.txt' extension afterward" between the "Download" section text and the actual download links.
