I got a new update. I installed it and it said that some of the features were not installed because they incompatible with this version of Fire. I figured "Okay" and continued. When Firefox opened it said I have the "Newest" version. Great, then how come some of the features are not compatible with the "Newest" version. That makes no sense!

It is possible that because of changes made to firefox, some other software used with Firefox may no longer be compatibile (for example some toolbars) or it is possible the software may work with Firefox, but the software does not recognise the version of Firefox.

First of all check the add-ons are up-to-date. Downloading, installing and using the Compatibility Add-on may help to allow such Add-ons to be run for testing, and hopefully some may actually work.

If you are having problems, please state the full name and the version number of any add-on or plugin software that is causing a problem.

I have Kasperski 2011 antivirus. When Firefox updated, a message said it was incompatible with my Kasperski. Kasperski updates regularly. The Firefox update said it disabled a portion of the Kasperski antivirus program. But when I checked the Kasperski program, it said it is running properly. Why would Firefox give that message?

Is it the Kasperski pasword manager that is being disabled and causing you a problem. If so is it appropriate to update it. Does this link help ?
