89.0 Update Borked Firefox on Startup?
So for the most part I rather like update 89. It looks snappy. One annoying issue I'm currently having is that Firefox will no longer open maximized on start up. I click the shortcut and it opens in a little window on the left side of my screen. I click the maximize button and instead of maximizing to full screen it moves the little window onto the right side of my screen. Clicking maximize a second time finally gets the browser to open full size. Why is it doing this and how do I make it stop? Never did this before 89, now all of a sudden it does it. I'd like for the browser to open fill size instead of clicking multiple times before it finally decides to do so. Thanks.

Close Firefox. Open your file browser to this hidden location:
- Mac: *~/Library/Application Support/Firefox/Profiles
- Linux: *~/.mozilla/firefox/Profiles
- Windows: %AppData%\Mozilla\Firefox\Profiles
- *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles
- Windows XP: C:\Documents and Settings\<user>\Application Data \Mozilla\Firefox\Profiles\
Search for the above file. Then rename or delete it. Restart Firefox.
