I am forced to edit proxy settings in Firefox texmaker miktex sumatrapdf and others which all work and have UI for this purpose.

I find adobe unwieldy. I usually use the lightweight SumatraPDF, but I find it is not the best for reading articles as it does not have any highlighting or annotating features.

I use SumatraPDF, it's the most minimalistic viewer out there, and it's open source.
