Please provide steps to replicate, links, and screenshot(s) of "Mozilla Firefox failing".

Hi, I just want to say that for years I've been using Mozilla Firefox as my default browser. I am very reluctant to want to change this but with all of the problems I'm having recently, I'm considering it. Can you please explain to me why there are so many problems lately?

So I attached a few screen shots, for example, Nordstrom never shows content from link of an email. Sometimes on other websites recently (usually merchants) the links do not work at all using mozilla firefox. Also in the past couple of months, I'm not able to use autofill or to manually fill in blanks to complete purchases. I attached an email from bombas with their response to my email expressing difficulty using their website to check out all using your browser.

In all cases, when I switch to Safari, everything works.

I'm sure I'm not the only person with problems using the Firefox browser. There's more problems lately than I encountered in the past.

Thank you for any help.
