I can get to the website, but not to my photos or share sites. It tries to load for several minutes, then throws me into a sign-in loop.

[Trying to upload an image, but no luck. "Uploading "Screenshot 2022-06-03 at 13-00-33 Sign in Shutterfly.png"...]

Anyway, Shutterfly works fine in Safari, but I don't like Safari.

I sincerely appreciate your efforts to help, but I'm a 74-year-old retiree and your suggestions are way above my tech level. I should tell you that I can get as far as the My Account page at the Shutterfly site, but then cannot open My Photos or Share Sites. I should tell you that I am running the latest version of Firefox and the latest Mac OS. I should tell you that I tried clearing my history and deleting cookies, an action I very much regret. Not only did it not affect the Shutterfly issue, but it also caused the loss of access to several other sites.

Because Shutterfly functions on Safari, I can only assume that the problem is neither with Shutterfly nor with my laptop. It must be a Firefox issue. It occurred sometime after the most recent update.

I can't be the only Shutterfly/Firefox customer having this issue. I keep hoping that someone from Firefox will connect with someone from Shutterfly, or vice versa, and unravel the glitch.

Meanwhile, I'm using Safari as my dedicated Shutterfly browser. I don't like it.

Hi Marty, I'm also on macOS, so when I saw this thread, I decided to create a shutterfly account and upload a test image. Logging in and accessing my test image works fine here. If you start Firefox in Troubleshoot Mode, does the problem still occur? To start in Troubleshoot Mode, go to Help > Troubleshoot Mode.

If the problem does not occur in Troubleshoot Mode, then you can disable your extensions one-by-one until you find out which one is causing the problem. For more info, visit Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems.

Chris, you are my hero! The problem turned out to be a newish extension, Privacy Essentials in DuckDuckGo. I disabled it, and Shutterfly was healed. Thank you so much!! ~Marty W
