Thanks for your quick response and helpful suggestion. Your assertions above are all correct. I had supposed what you conjected: it is likely that unbeknownst to me one of my add-ons changed a setting.SvenG wrote:Hmmm, so what else can it be? It works in a new profile, so it's no general problem. You said you tried disabling all your addons and that did nothing, right? If it is not addons, it should be settings (maybe changed by addons). Well you could try to reset your settings. You should be able to do that from about:support (just type that in your address bar and hit enter), there is a reset button in the top right box. If you do not feel adventurous make a backup of your profile *first*.
I followed your advice. I just reset Pale Moon. Now I will reinstall my add-ons. I hope this doesn't happen again because reinstalling and reconfiguring Pale Moon add-ons once is a minor hassle, but doing it regularly would be more than a minor hassle.
The Internet generally, as well as software like Pale Moon and Firefox add-ons, reminds me of the Wild Wild West of the late 19th century in the United States with the accompanying lawlessness and disorder. I am not in favor of some Orwellian Big Brother government agency (think Great Firewall of China) sanitizing the Internet.
But the notion of the Free Market taking care of problems justly, is absurd as well. As a Jew it probably would not suprise you that I would favor a committee of wise rabbis (Talmid Chacham) to make the rules. But here in 'merica (America) that is not likely.
In the meantime I will continue to navigage my way through the lawlessness and disorder of the Internet.
