Because all the browsers I tested were on my primary (daily-used) MX-19.4 Xfce. Waterfox and Pale Moon were the only two browsers of the four that I have installed that were not able to get past the CAPTCHA test on my MX-19.4 Xfce installation. So I went to my MX-21.3 Xfce "evaluation" installation ("evaluation" can be interpreted any way you want) where Waterfox and Pale Moon have the latest MXPI versions. Pale Moon passed the CAPTCHA just fine. Waterfox was "the problem child". While it did a little better than it did on MX-19 using version 2021.04.1, it still hung up on the CAPTCHA in MX-21.3 ("little better" meaning that the CAPTCHA in MX-21 at least displayed the square (without the green checkmark) but still had a never-ending circular progress wheel).
None of my browsers are up to date, much less with the latest versions even though it would be VERY simple and fast for me to get the latest versions in MX-19.4 for Firefox (manual installation) and google-chrome (MXPI automatic installation). I'm good where I'm at.
I have Firefox at 128.0 because that is the minimum version for the Firefox root certificate to verify signed content and add-ons. I could easily (manually) install the latest version (137.0.2) on my MX-19.4 but have no interest. Firefox is my primary and daily-used browser that I have had zero problems with. If/when a problem occurs with an out-of-date Firefox I'll just manually update it like I did updating to 128.0 a few months ago. I know many will call that just plain stupid, etc. but they are not me and I am not them...I don't care.
Chrome is on 133.0.6943.101 on my MX-19 and even though the google-chrome updates keep coming (monthly or more often) through the MXPI almost a year after the MXPI stopped updating packages, I put a "hold" on updating Chrome because, based what Chrome has recently done in the past few months, I believe that Chrome will soon permanently (!) disable uBlockOrigin from that browser (the mentioned Chrome version disabled it just a couple months ago but Chrome did not entirely disable it or remove it; I just re-activated uBo). If I ever have a browser where uBo no longer works then I will stop using that browser. I use Chrome mainly because it does a better job at translating web pages than Firefox and the extension that uses. I copy the URL from Firefox and then paste it in Chrome to view.
Waterfox is rarely used and so it is not worth manually updating on MX-19.
Ditto for Pale Moon.
I have no desire to update any browser I have at this point. I am aware of the risks, potential problems, recommendations, etc. etc. I'll take the risk(s) thank you.
