the menus appear initially very large or very small

When in the Firefox browser if I click on a menu, it appears very large or very small. When I move the arrow in the menu change to the right size. This has not happened before. Is there a solution?

Try Firefox Safe mode to see how it works there.

A way of solving problems, which disables most of the modules.

The problems of Firefox using Firefox SafeMode

When in Safe Mode...

  • The State of plugins is not affected.
  • Custom preferences are not affected.
  • All extensions are disabled.
  • The default theme is used, without a character.
  • userChrome.css and userContent.css are ignored.
  • The layout of the default toolbar is used.
  • The JIT Javascript compiler is disabled.
  • Hardware acceleration is disabled.
  • You can open the mode without failure of Firefox 15.0 + by pressing the SHIFT key when you use the desktop Firefox or shortcut in the start menu.
  • Or use the Help menu option, click restart with the disabled... modules while Firefox is running.

To exit safe mode of Firefox, simply close Firefox and wait a few seconds before using the shortcut of Firefox (without the Shift key) to open it again.

If it's good in Firefox Safe mode, your problem is probably caused by an extension, and you need to understand that one.

Or it could be caused by hardware acceleration.

When find you what is causing that, please let us know. It might help others who have this problem.
