Problems loading some websites.

I just replaced my MacBook Pro with a newer one, running the same OS (10.15.5). I migrated everything onto the new laptop from my Time Machine back-up disc. Everything seemed fine until I discovered that certain websites were not loading properly. Examples: Weather Underground starts to load but almost immediately goes to white screen. Bank and credit card sites display the Log In page properly, but once I log in the screen goes white. The site of one newspaper to which I subscribe opens with proper text and formatting, but no photos (white where photos should be), and the sites topmost menu bar functions do not respond, so I cannot even log in (other newspaper sites I subscribe to seem to be fine).

The problem sites loaded and operated fine when I tested them with Safari, but I am a longtime Firefox user and prefer it (especially since Safari apparently no longer supports Dashlane).

I tried changing my Firefox privacy & security setting to Standard. I have restarted Firefox and my laptop repeatedly while trying the few things within my ken. Any help would be appreciated.

Chosen solution

I believe that I have solved my problem. I wondered if, when I loaded my new laptop from the Time Machine backup from my old laptop, there could have been some part(s) of Firefox that corrupted or did not copy properly. So, without doing anything to the Firefox that I had on the new laptop, I downloaded the Firefox installer again and installed a second copy of Firefox. I then opened that copy and went to the websites that had been giving me trouble. All of them worked. So I then exported all of my bookmarks to html from the first version and imported them into the second version. I now seem to have a fully functioning Firefox browser. What a relief.

McCoy and Andrew,

Thank you for you responses, which I read late but hopefully not too late. I had already called the number provided by wehelp 106 and had followed his instructions to give him remote access to my computer. I did think that it was odd that he did not ask me more specific questions about the problem I was experiencing, and I also thought it odd that he had me do all of the work in Safari. When he said to leave the screen just as it was and to wait for 15 or 20 minutes for him to call me back, I checked my gmail on my old laptop and found your messages. I immediately closed whatever I could and then shut down the new laptop. Right after that he called me to ask what happened. I told him that I had received multiple warnings about him. He hung up.

In hindsight, I feel very stupid. Normally I am very keen to potential spam and such like. For some reason, I felt that his reply indicated some sort of Mozilla endorsement, which, again in hindsight, was foolish on my part. I only hope that I caused myself no harm, and that I can safely restart that computer without his having any entry.

And if anyone here can provide help for my original problem—via posts on this site—I would appreciate it.

Thank you, Shashank, for taking the time to reply and for trying to help solve my problem. Unfortunately, neither of those possible solutions helped. This is very frustrating, as I find more and more websites which will not function or show complete content. I made sure that all of my Firefox Preference settings on my new laptop are identical to the settings on my old laptop (on which all websites display and operate fine). Same settings, same OS, same version of Firefox—I don't understand why the problem exists. Only real difference is that it is a newer MacBook. I do not normally subscribe to conspiracy thinking, but, as much as I love Apple products, the company has been guilty of bad behavior in the past: is it possible they have made a change which affects how Firefox runs, in order to try to drive people to use Safari? If I cannot fix this problem, I will be forced to change browsers, as many of the affected websites are very important to me.
