Opening the browser should put you somewhere useful. Firefox home page choices can become confusing when a new window shows one page but restarting brings back yesterday's tabs. Those behaviours can come from different controls, so first identify exactly which action gives the unexpected result.
Quick Answer
Open Firefox Settings and look for the Home or Home and startup section. Choose the default homepage, a custom address or a blank page, then inspect session restore if previous tabs still return at startup. This is an R0 setting change and does not require a faster laptop or a browser reset.
🏠 Test Home and a new window separately
Write down the trusted address you want to use and check it before saving. A mistyped address is a navigation problem, not evidence that the choice failed. After setting it, open a new window and use Home if that button is visible.
Menu names can vary with Firefox's version. Search Settings for home if the expected panel has moved. Avoid old instructions that assume every installation shows the same toolbar buttons. The key is to change the homepage control, rather than a search engine or the address of the tab currently open.

🗂️ Decide whether old tabs should return
Session restore answers a different question: should the next launch resume the previous browsing session? That may be convenient for an unfinished project, while a predictable start page may suit a shared household computer better. Choose based on how you use the device.
Before closing anything, save important page addresses and finish unsent forms. Then test the startup behaviour deliberately. A new-window check by itself cannot establish what will happen after the browser exits. If you are comparing asus laptops, keep this software preference separate from the memory and display requirements of a replacement computer.
🔍 Avoid broad cleanup for one preference
Deleting every cookie or reinstalling the browser is an unnecessarily large experiment when the only complaint is the first page you see. Start with the named control, record the previous value and make one change. That gives you an easy way back if you preferred the earlier behaviour.
Shortcuts can also change what action you perform without changing any setting. With gaming keyboards, distinguish a key assigned to open a new window from one that goes Home. If an unwanted address keeps returning after you have saved a different choice, investigate extensions or managed settings rather than assuming the physical keyboard caused it.
Frequently Asked Questions
Why do old tabs open instead of my homepage?
Session restore can reopen your earlier tabs. Check the startup choice separately from the homepage setting.
Can I start with a blank page?
Yes. Firefox offers a blank-page homepage choice. Confirm which window or startup behaviour you are changing.
Can several pages be used as home?
Firefox supports multiple custom homepage URLs. Use only pages you want to open together.
Where are the options?
Open Firefox Settings and find Home or Home and startup, depending on your version. Check the homepage and startup entries.
Will changing home delete bookmarks?
A homepage choice is not a bookmark deletion command. You do not need to remove saved sites to change it.
Is a new laptop needed for this?
No. A wrong starting page is normally a browser configuration question, so test the R0 settings change first.
