Cannot access Staples.com
Lately, I cannot get to staples.com. I think it started after the last update, but I'm not sure. I never had a problem before, and Staples is a well-known national company for office products. I've restarted Firefox in troubleshoot mode, but the result is the same. Chrome and Edge have no problem accessing the site, so it's a puzzle why Firefox cannot. If anyone has any ideas about how to proceed, I'll appreciate it.

Since Staples works in Chrome and Edge and Troubleshoot Mode did not help, I’d try clearing the site data for staples.com specifically. Also check Settings → Privacy & Security → DNS over HTTPS and temporarily switch that setting to the default or off to see whether it makes a difference.
If it still will not load, try a new Firefox profile. That can tell you pretty quickly whether the problem is something specific to your current Firefox profile.
