Firefox - Right Click Menu Flickers

I am using Firefox 17.0.1. My second monitor an AOC 1950W was replaced after developing a fault. Immediately I discovered a problem when using Firefox. Right clicking on a web-page resulted in the Right Click Menu flickering and disappearing making it difficult if not impossible to select a menu item. There was no problem on the main display. Using Chrome on this display there was no problem.

I checked settings were correct and that drivers were up-to-date to no avail. A Google search for "firefox right click menu flickers" produced the following suggestion:-

Try to disable hardware acceleration.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available" .

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

Untick box and restart Firefox, this solved the problem.

Firefox 4 Google Toolbar Problem - Fix - Updated

UPDATE: 25th April 2011 - The problem seems to have been resolved by a recent software update.

Since I upgraded to Firefox 4 I have been unable to select from the search box drop-down list

When you attempt a search from the search box on your Google Toolbar it may not allow you to select items from your drop-down list of web history or search suggestions.

As a workaround, try using your keyboard up and down arrows to navigate the drop-down list to select your search history, press return to select.

Firefox Background Removal

When Mozilla installed version 3.6.10 of Firefox today a very irritating background appeared! Not immediately obvious how to remove this. Apparently you need to go to:->

Tools>Add-ons>Themes click the active background to uninstall.
