Diễn đàn hỗ trợ Firefox

I have a fresh install of Debian 12.5, which came with Firefox 115.7.0esr. Firefox is inconsistent in following the settings I put in. For example, I specified the download folder, but it still automatically saved to the original default folder. But when I clicked to ask me before downloading, it does! And it gives me the 1st option to save the the folder I specified. But if I uncheck the "ask me" button, it goes back to putting downloads in my home directory, which I don't want. Another example is I've set it to "open previous windows and tabs on startup", but it doesn't. When I close Firefox with several tabs open, the next time I start it I have just the home tab. Yet when I look in "settings" it still says it's supposed to be opening my previous tabs. This is more annoying than the download issue. How can I get Firefox to follow the settings, which ARE being saved?
