Does the IE legacy plugin for Edge still work? Need help! or How reliable is the IE legacy plugin for

Yup, it’s a dumpster fire. The plugin worked fine until last month, now it’s useless.

Try running the sites in Edge’s "IE mode" directly instead of relying on the plugin. Go to edge://settings/defaultBrowser and set it to "Allow."

If that fails, maybe check out Firefox with an IE emulator add-on? Not perfect but better than nothing.
