Do not lilke the changes in 4.0. At least two sites do not work as before: EMC Powerlink and the IBM HMC interface.

Moving the refresh, moving the start of the tabs, cannot double click when tab bar is full. I do not understand changing a user interface that everyone is use to. I have also had several time when the browser freezes.

The EMC Powerline site hangs when I click on the "My Support" link. The IBM HMC loses the last line of the list of LPARs. Some of the spots on the HMC page are not correct.

I'm having the very same issue with emc powerlink.. Thought at first that it was some issue on emc end.. but considering i can access the site with no issue with IE8, it might actually depend on some change implemented in ff4 :/

I do not have issues with FF 3.6 but I am seeing issues with FF4. From the error messages it seems to do with the core.js script used for the my support link. The error message in the log is bb is null. I can only guess that because of this the tons of warnings for dropped declarations are a result of the core.js not running properly.

Here is the error message: Error: bb is null Source File: https://powerlink.emc.com/nsepn/webapps/btg548664833igtcuup4826/staticKmSearchResources/KM-3_20-20100423-112230-528/Backbase/engine/core.js Line: 1

please can you try: - Going to about:config - Entering "html5.parser.enable" in the filter box (without quotes) - Changing it's value to false - Retrying the page in question and seeing if it helped - Afterwards, resetting html5.parser.enable back to true
