This is a super huge frustration for all of us :/ It seems that all the popular browsers have taken away the workaround we used to have to allow mixed content to be viewed on websites. I've been looking into a new work around (either having to download an older browser version or a 3rd party plugin etc... no dice yet) But to ACTUALLY fix it, changes would have to be made to the coding of the site to use different javascript libraries or different methods of coding all the things that use javascript on the website all together. This has to be done at an Administrator/Owner level so us staff and users alike are stuck unfortunately.
