Can't remember where the discussion about Firefox TLS compatibility was, but...
From the 62.0.2 notes:
Restored compatibility with some sites using deprecated TLS settings (bug 1487517)
It's funny, but I was just updating Firefox and saw this (using Chrome) while I was waiting for it to restart.
While pondering Chrome, I'm using MS Edge (hangs head in shame). It runs video great and generally is very good. But the reason I hate it is that it won't let me change my search engine. As I hate Bing more than life itself, I have to go to google.com every time I want to search anything. I'm thinking of making it my home page.
Though I don't normally use Edge, I have Google set as my search engine. I hate Bing, as well. With that said, though, I've never gotten in the habit of using any browser's search feature. I always go to Google to search, and I have it set as my home page. That's just me, though.
Does Google not show up on the list of search engines for you? To make sure it does, you have to go to, or be on, google.com when changing the default search engine.
The instructions for doing so... https://support.microsoft.com/en-us/help/4028574/windows-10-change-the-default-search-engine-in-micr...
I finally gave up on Edge and installed Chrome and now I have my Google search engine. 😀
I don't blame you. I think Edge could be a good browser, but it needs some work. Glad you got your Google search engine.
