Steps to reproduce

When I visit many web sites (www.destructoid.com for example, including other pages on the domain instead of just the root level), Edge downloads a randomly named .HTM file and saves it to the Downloads folder. When I open the HTM file, it opens the website normally. It happens at many websites and doesn’t seem random. destructoid.com always does it, but many other websites work fine. I’ve read about it being how Edge handles mime types or something like that. This just started happening within the past 5 or 6 days, it was fine before then. Just for reference, www.gizmodo.com works fine and www.destructoid.com doesn’t.


Comments and activity

  • Keeps happening to me too. Its been happening for the past month. Cant track ups packages with edge anymore. Way too many websites cant be accessed because of this bug. This need to be fixed.

  • Also happening to me. I had assumed it was the uBlock Origin extension causing it but it still happens even after disabling it.

  • Same here with multiple websites. I tested the above www.destructoid.com (never went to it before) and can confirm it asks to save a random generated .htm file instead of opening it.

  • Interesting. This doesn’t happen in our test environments, though. May I ask for a dxdiag upload or some hardware details so that we can investigate further, please?

  • Turns out for me at least it is ublock origin that is causing it. I did turn it off and nothing changed, but when i uninstalled it and switched to adblock plus the problem went away. I reinstalled ublock to make sure and the issues came back. Whitelisting the sites that are affected lets me go to the sites while still using ublock.

  • Thanks @Jonathan B., whitelisting works for me as well.

  • Changelog of Build 15055:

    • We fixed an issue that could result in Microsoft Edge unexpectedly attempting to download certain webpages rather than navigating to them when the uBlock Origin extension was enabled.
