home page windows shrinks

Firefox is supposed to remember the stretched size. If you were to press Ctrl+n to launch a new window after stretching the first window, does that have the new size or the small size? If Firefox can't seem to get window sizes right, it can indicate a corrupted settings file. Since the file is difficult to edit, we generally recommend removing it and having Firefox create a fresh one. This will hide the menu bar and bookmarks toolbar, so you'll have to turn those back on if you normally show them. And here's how: Open your current Firefox settings (AKA Firefox profile) folder using either * "3-bar" menu button > "?" button > Troubleshooting Information * (menu bar) Help > Troubleshooting Information * type or paste about:support in the address bar and press Enter In the first table on the page, click the "Show Folder" button. This should launch a new window listing various files and folders in Windows Explorer. Leaving that window open, switch back to Firefox and Exit, either: * "3-bar" menu button > "power" button * (menu bar) File > Exit Pause while Firefox finishes its cleanup, then rename '''xulstore.json''' to something like xulstore.old. If you see a file named localstore.rdf, rename that one to localstore.old. Start Firefox back up again. Do windows display normally again? You can use one of these methods to show the toolbar list and select Menu Bar and/or Bookmarks Toolbar there: * right-click a blank spot on the tab bar (or the "+" button) * tap the Alt key to activate the classic menu bar > View > Toolbars * in Customize mode > Show/Hide Toolbars (see: [[Customize Firefox controls, buttons and toolbars]]) Success?
