Mybrowseraddon.com suprised me by appearing as the homepage Add-on site after installing Smart HTTPS posted by ilGur at https://addons.mozilla.org/en-US/firefox/addon/smart-https-revived/?src=recommended
Notice it is actually SMART HTTPS REVIVED . What is going on?
That homepage https://mybrowseraddon.com/smart-https.html?version=0.2.5&type=install so helpfully suggests to post all bugs on that page not via Mozilla.
Scrolling down the description in Add-ons - after poster ilGur I see homepage = the above https://mybrowseraddon.com/smart-https.html
This is displayed only after installing it. Before then it is disguised via Homepage general link.
Notice that oddly enough this Mozilla Add-on mega-site does NOT USE HTTPS for its own webpage.
I am not happy. This mybrowseraddon.com mysteriously prompted me after every Add-on update with a similar page 2.5 years ago, on multiple computers. I complained about it on Mozilla. I recall the difference in 2016 was the Add-on was clearly not the desired ad blocker from the true author, solution = RESET Firefox, deleting all Add-ons.
