Security offense!! Access denied! when trying to save a page in Firefox

[scheltel]

I'm getting de error message 'Security offense!! Access denied!'  when I'm trying to save a page in WB 2.8.2 using Firefox 5.0.1.

In Google Chrome 13.0.782.112 and Safari  5.1 (7534.48.3) the page is correctly saved.

Any ideas what can be the cause?

  Thank you!

I had the same issue. I fixed it in Chrome, and then could work in FF as well. Still I find it rather strange.
Can anyone explain what the multi form switcher is all about? Why should we use it - or not? And how comes this issue only occurs seldom?

Without Multitab you have two locks on your door. With Multitab you only have one.

So how comes in this particular case I can have only one lock on my door?
Why does FF sometimes prevent a second lock? Can you elaborate a little on how the multiform switchers work and what the parameters which we can set are about? I presume I'm not the only one who doesn't have a clue and would appreciate some more information...

It's not too hard to understand:

right now WB has two security levels for forms. Both are based on tokens for each saving process. Tokens will be generated if a form opens.

• Default (highest level)
  One token only can exist at the same time. A token can be used only once. To open second form in another window/tab, will create a new token and delete the previous one. So the first form loose it's token and become invalide.
  
• MultiTab (high level)
  Multiple tokens can exists at the same time. Each of these tokens is valid for a defined range of time. So it is possible to open more then one window/tab simultaneously.
  

To time we still have a little problem with FireFox. FF generates an security error at first calls. If this issue occurs, you can simply wait for 24 hours (please, don't call us crazy..) or use another browser for the first time saving a settings in backend. After this, FF will work completely normal. It is a mystery, but we work on it.

Thanks for your explanation! Glad to be able to understand some of the principles behind it.
