Menu Bar 'View' drop down menus do not work except 'character encoding' option
FF V33.0.1 For past several updates I have been experiencing problems with dropdown menus. 'View' on Menu Bar is one exzmple. Pnly 'Character Encoding' option works correctly. Similar problem is occurring in many other places including LastPass extension which I use a lot.
An empty menu appears to the right with no entries. But the problem is not consistent.
Starting FF in safe mode cures the problem for FF Menu Bar and other FF issues. But I cannot trace which plugin or extension is causing the problem.
Any ideas

Hello makatikid, try disabling graphics hardware acceleration and check it again.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
- Open Firefox Options window as follows:
- click the menu button
and select Options
- click the menu button
- In the Firefox Options window, click the Advanced tab, then select General.
- In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
- Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
In firefox safe mode, hardware acceleration is disable.
Thank you.

The disabling of graphic acceleration solved the problem. However, I cannot understand why this was the cause as it was working fine with graphic acceleration for years until several weeks ago.
Was the problem caused by FF upgrades or Windows upgrades. Anyone know the answer.
I have this same problem, which began precisely with the release of 33.0.1. I have been downgrading back to 32.0.3, where this problem does not occur. Each time 33 has had a build update or a release update, I've gone ahead and let the update take place, then tried again, at which this problem came back. This has been the case with 33.0.2 and 33.0.3 as well.
I just went ahead and updated to the latest 33.1 release and found this problem still exists. Before downgrading once more back to 32.0.3, where this problem does not exists, I did a search, found this page, and followed the instructions set forth by ideato.
However, I have concerns. Generally, hardware acceleration is something that gets used for things like--oh I don't know, watching video? Why would hardware acceleration be used to display a drop down menu??? What is wrong with this picture? And why are there no problems whatsoever in 32, but this problem manifests in every build and release of 33?
I think there is a problem here that Firefox developers should look into more carefully. I don't think it's cool to behave dismissively toward users who have stuck with this product through thick and thin since it was still called Netscape.
So now that I've disabled hardware acceleration in Firefox, what other problems can I expect to manifest from having done so?
