Firefox searching instead of dns resolving internal websites
I have multiple internal websites, which all follow the pattern of [site.one.two] which resolves fine using the internal DNS server i have configured by going to https://site.one.two and through other programs via site.one.two, and all the [one.two] suffixes are blacklisted from being resolved with DoH in firefox, but it still forces a web-search, even with searching from address bar being turned off, instead of resolving through my local DNS server (local server resolves local domain suffixes, anything else gets resolved through cloudflare DNS). I haven't found a fix in any other forums, and there are enough unique internal addresses that manually adding each and [every site.one.two] as an exception would be something i would like to avoid. Is there any way to tell firefox to resolve through DNS first for addresses or domain suffixes?

I assume the .two in your addresses does not map to an official TLD (like .com or .net or .xyz) or one that Firefox has whitelisted in advance (like .internal or .local or .test).
When you type site.one.two in the address bar, Firefox will usually show "Search with [default search engine]" in the top row of the drop-down before you submit the entry. Then after your search results appear, Firefox may show an info bar above the page asking whether you meant to go to http://site.one.two/ -- with a button to go there. Are you seeing that bar?
For dotted host names on unofficial TLDs, Firefox sends your input to search first and checks (or should check) DNS second, unless you signal that it is meant to be understood as a host name by modifying your query in one of these ways:
- add a slash after: site.one.two/
- add the protocol before: https://site.one.two
If you want Firefox to always resolve dotted host names for an internal .two TLD without having to add anything, you can create a new preference:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.
More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.
(2) In the search box in the page, type or paste browser.fixup.domainsuffixwhitelist.two (replacing two with the actual TLD) and pause while the list is filtered
Firefox should display a bar with Boolean Number String and a "+" button.
(3) Keep the selection on Boolean and click the "+" button to create a new preference.
(4) If the preference does not end up being set to true, double-click it (or click the Toggle button or Reset button at the right end of the row) to set its value to true
Now when you type site.one.two in the address bar, instead of saying "Search with..." it should say "Visit".
Success?

yup! that works perfectly, makes sense why firefox behaves that way. all my variations of `.two` are invalid TLDs outside of the local network
