Thank you very much the-edmeister, but I prefer not to have to download programs if I can avoid it.  :o)

By chance I clicked on the Default button and lo and behold the little animations stopped! However...

......I just noticed that when I open Firefox, instead of showing the usual home page with the search window, etc., it shows the last website I was using! And only when I click on a 2nd Firefox button it does show the normal page.

If you happen to know why and how to fix I'd appreciate it a lot!

Thanks again so much! Adela

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

Delete the storage\persistent\moz-safe-about+home folder in the Firefox profile folder with Firefox closed ("3-bar" Firefox menu button > Exit/Quit) to remove snippets stored in IndexedDB and make Firefox use a default snippet set.

You can use this button to go to the currently used Firefox profile folder:
