Since updating the other day to Firefox 3.5.5 and the latest Java v6 u17 my browser has been intermittently crashing. I read on Google that this could be caused by one or both of the Java Plugins. I wondered is it ok if I disabled them as a test to see if it stops Firefox crashing, or does the browser need Java to operate. As add-ons I use No-Scripts, Ad-Block Plus, WOT and I also have Download Helper installed. As far as plug ins go I have the two mentioned Java ones as well as the Mozilla default plug-in, the Shockwave Flash and VLC Mediaplayer plug-ins. Otherwise I have the Microsoft DRM and Windows Media Player plug-ins switched off. I have cleared the cache and also cleaned out my cookies. The only Cookies on my PC are my regularly visited sites. Does anybody have an idea on what is causing Firefox to have these crashes?. All of the above are updated to the latest versions.

With regard to your first question: disabling Java will not affect the browser at all. You will simply get a notice on pages that use Java that "a required plugin was not found." All other pages will work normally.

Thanks for that Andrew. The problem turned out to be a conflict of some sort between VLC player and WMP11 in Firefox and nothing to do with Java but still nice to know that Java is not a critical program.

Glad you got your problem fixed.

Only rarely, in my experience, is Java needed. I have it disabled in my Firefox settings.

Tools --> Options --> Content

I remove the checkmark next to Enable Java.

On those occasions when I do need it, such as for BC Chat or my job's training program, I put the checkmark back then refresh the window or tab.
