I’m not “rejecting your choice” to use anything, mate. So, you can take that claim and toss it away.
I asked what I did precisely because I knew PureBrowser is a fork of Firefox.
If you wish to use Windows in place of Linux, then be my guest. I never recommended that to you nor did I insinuate it. You have the choice to do what you wish, and in this case you’ve done just that albeit inappropriately.
I agreed with you until you admitted to not wanting to install Firefox—as irrelevant as it may seem.
You have every choice in what you use, especially on Linux.
Incidentally, it goes without saying you have me at a disadvantage since I’ve never used PureBrowser.
I can’t tell you why that site is flagging your “browser of choice”, but if it’s based on Firefox as we know it to be, surely there must be some other reason for this to be occurring.
On the same line of reasoning, if PureBrowser is based on Firefox, surely you can simply adapt your configurations to Firefox.
Unfortunately, I don’t know the answer to the first assumption and since I’ve never used PureBrowser, I cain’t make in on the second one either.
Do I think you should be able to use whatever browser you want to use without being forced to use something you don’t necessarily need to use? Yes.
Do I accept that some forks run into issues every now and then that originating source doesn’t? Yes.
It’s just a fact of life and why I only used Pale Moon for a month until I quit.
I realize it’s a much more daunting issue for you since this is presumably the default browser that ships on PureOS. I’m not saying what’s happened is what you deserve, but rather something that can happen.
My instinct would tell me to report a bug or something. Since I don’t know where to do that, I say Google it.
