I have literally endured countless hours of grief over the past years, because sites have become ever more sophisticated, to the point of causing aggravation. Today, after spending hours figuring out which clothing to buy, then analyzing my shopping cart, a site kept kicking up a message that my phone number doesn't match my billing info. So I thought that either it wasn't accepting my entered promo code, or else that the programmer failed to coordinate correctly with Paypal. Because my phone number certainly DID jive with my billing info & the paypal acct. info. Furthermore, I sometimes run into forums which automatically time me out, and then I have to login again. Whether for security reasons or whatever, the programmers who automatically time-out cause countless grief. It's a long story, because I'm then made to endure asinine customer "non"service who are condescending in a drawn-out way, who fail to believe my real issues (because they don't offer a way for me to email or fax them a screenshot), and don't believe me when I tell them that I did everything properly, but yet its either looping or else kicking back unwarranted error msgs. Due to them not enabling sending a screenshot they waste my time by condescendingly telling me that I need to "blah-blah" and then it should work. Or else they say the promo code is wrong, or the phone number is supposed to be numerals and no hyphens. Basically, they say everything EXCEPT: Are you sure you're still logged in? Are you aware blah-blah is case-sensitive? So that's why I came here to ask if there's any such Add-On which FLASHES A RED WARNING whenever I get various STUPID error messages. I.E. the software should detect when a site is giving me an error msg. Whereupon a warning should remind me: PERHAPS THIS SITE AUTOMATICALLY LOGGED YOU OFF, ....OR ELSE PERHAPS IT'S REQUIRING A CASE-SENSITIVE PASSWORD?
