How to Avoid Limitations on BitWarden in FireFox Browser Private Windows

From my research in the BitWarden Help database, it says: “Your vault will lock every time the browser extension closes, unless you set vault timeout to Never. Alternatively, you can use the browser extension as a sidebar to bypass this limitation.”

How do I set Vault Timeout to “Never” in my Private Browsing on my FireFox Browser?

Does doing that cause security concerns?

I have tried the browser extension as a side bar, but that disappears sometimes and I have to re-open, AND, it does not allow me to click on the item to automatically load the UID and PW.

Is there anyway to make this automatically load from the side bar version of the browser extension, rather than the copy & paste method?

P.S., I don’t know what those required “Tags” mean. Can someone interpret those things to make sense as to which I should select?
