Firefox 91.0.2 Very Slow To Start

[RedBar]

Ever since this update my FF takes a minimum 20-30 seconds to load, once it has started it is ok however noticebly slightly slower when loading image intensive pages.

This is not a system issue, this is a FF update problem, all other browser loading pages and images immediately.

Searching there seems to be several with this problem however no solution.

Firefox has a generic document which might help [support.mozilla.org...]

BTW, i'm not experiencing this problem.

Thanks however I have already seen that doc.

My other two Win10 machines are also not expericing this problem, strange.

Need to check all machines to see if there's anything that jumps out.
