Firefox normally opens the same size as when you last closed it. Personally, I don't have stuff like the browser start when I boot, so I can't say I've ever checked what it does in that case, but it doesn't seem logical that it would pick a small size to open.

Exactly how did you arrange for it to start at boot, just by putting it in the StartUp folder?

 

Take that bottom right corner and pull FF completely open. After closing and reopening it, you should be back to normal.

 

Well I have tried everything. Settings, Pulling bottom corner like you said, nothing works. I do know how to use a computer. I have a family member, that has been on computers all her life and she can't do it either.
I am going to remove firefox, reboot, download firefox again and reboot.
If it does not work, I will have to switch to my wife's favorite browser "Chrome".

Thanks

How to open firefox maximized? | Firefox Support Forum | Mozilla Support ?

Or, while Firefox (or most any other browser) is open, simply press [F11] to toggle full-screen On/Off.

Something else I've heard is get the Firefox window the size and placement you like then while holding down the [Ctrl] key, click the red [X] to close Firefox. Now reopen Firefox and it should re-open back to the position and size you had it.

???

 

You don't have to remove FF. Just download it and it will copy over. In any case, you won't lose your FF profile.

 

There is something going on beyond me.

I am not a techie like you guys but I know my way around computers. Simple problems I have always fixed eventually with often help from here. This one does not want to fix.

SpywareD I tried the link you provided but the thread is old and it seems "properties" can't be accessed anymore on new versions (I hope I am wrong here), I did what he said and did a web search on how to find the properties on new versions to no avail.
I can't find in settings anything letting me start Firefox maximized either, in older browsers tutorials I do. (Again I hope it's me too).

It works when I press F11 but all the buttons (Close, refresh, maximize or minimize...... are gone). So I right clicked and found the option to display the toolbar. Well it does not appear.

The CTRL and X trick does not work. I closed and tried 5 times.

No way to put the cursor on the borders and drag. I have known this for 20 years. I just tried on Chrome and it works like a charm.

Corday I just downloaded firefox over firefox like you said and no go. It placed a new icon on my desktop, I clicked it and bingo it opened maximized. Closed and retried several times and it does not work.

I looked at my extensions, I have Bitwarden my password manager, HTTPS everywhere and Ublock origin. No clue why that Ublock origin is there but these 3 have been installed forever.

I am going to reboot after I finish a few things I am working on. This got to fix it I hope.

Otherwise I will just have to open it and click on maximize twice or use Chrome.

I really appreciate all the help and time in helping me. It's not you or me, there is some sort of deeper problem.

Thanks again

In my Firefox 95.0.2 64-bit, grabbing an edge, or a corner of the window and pulling it works for me here.

And, with only a single Firefox window open. resize it, place it where you want on the screen, then while holding down the left [Ctrl] key and use the mouse to click the red [X] in the top right corner of Firefox. Re-open Firefox and it is exactly back on the screen where I had it as well as being the same size.

Windows 10 Pro 64-bit version 21H1 (build 19043.1415).

 

Problem fixed. The reboot did it. It opened small as usual but now lets me drag the sides to fill the screen. I then closed reopened and it stays maximized. I tried 6 times.

Thanks so much for everyone help

Try Right-clicking in Firefox icon/ Properties and make sure it's set to Maximized.
Hop this helps

 

One last shot form the "old days". Instead of closing from the "X", when in full screen>File> Exit.
