Window sizes settings have somehow changed and my windows do not open in the correct size anymore. How do I get my original window sizes to come back PERMANENTLY?

After upgrading to FF 10.0, my window sizes are not correct. I use a web-based invoicing system and my invoice windows used to open to the size of the invoice. Now, it opens invoices in full screen. I need the invoice windows to open the way the site tells them to open. How do I make that happen again and never change after that?

Hi,

You can try to toggle Move or resize popup windows in Tools (Alt + T) > Options > Content > Advanced (beside Enable Javascript) and keep the setting that helps.

Nope. No go. Still need a fix for this one.

Please also check in Safe Mode. Safe Mode is a temporary diagnostic mode and you can exit it anytime and start Firefox normally.

Great. Sizes are correct in safe mode. Open in normal mode, same problem. So, what does that mean? How do I fix this?

more options

Safe mode disables the installed Extensions, themes (Appearance) and Plugins in Tools (Alt + T) > Add-ons. So it could be that an extension is causing it. You can try to isolate it starting with script blockers and similar extensions and Disable or Remove it.

Please also note that safe mode also disables hardware acceleration: Tools > Options > Advanced > General: Use hardware acceleration when possible.
