Roop Unleashed not working in my browser

[jaccydee]

I have installed the latest Roop Unleashed - not sure if this was totally successful because...I use Firefox browser and clicking anything on screen does not work - i.e. I can't upload anything and I can't go into settings.
I tried the RU interface in Edge browser and whilst it lets me click into settings - I tried uploading a source picture and it just kept loading forever - so I had to end the operation.

I don't think it's my browser extensions because I tried disabling them with the same results.
My browser(s) work ordinarily.

Here is what looks like a python error (because it's blanked out) : https://www.imagebam.com/view/MEVT131
I tried downloading Python 3.10.14 in order to install it - but couldn't find a an .exe file within the unzipped tarball (I'm using Windows 11).

Not sure how to proceed..?

EDIT

Ok, I have just tested the localhost interface in a Brave (Chrome based) browser and it works fine - so this problem is due to my browser of choice - Firefox. (I tried an older version and installed an older version of Python separately. I noticed when I uploaded a source picture - a Buffalo.zip took a while to install in the cmd window).

So my question is - How can I get RU to work in Firefox?

EDIT 2

Found the solution. It wasn't my Firefox extensions - but it was due to hardening of the browser via about:config which changed my security settings to custom. To fix this - I used about:profiles to create a second profile, and after importing my old bookmarks, etc I deleted the original problem profile and set the second one to default.

On another note - I am pretty sure that if you interrupt a video early from processing - the output video will not have any sound because the sound is appended to the video right at the end of processing. I originally thought I had a sound problem, but after leaving the video process to complete on the next occasion - it had sound.
