Sorry for my dalayed comment.
1] How can i make a break in text because some text is cut because of non-resizeable window?
Unfortunately you cannot make a explicit line-break. Because some label element are single-line.
This problem is very difficult. To solve this problem, I think I have to change "Browser" panel design.
2] What does the function "Allow to dispatch left click only"
under "Security > JavaScript > More Advanced > [ ] Allow to dispatch left click only"
When this option is enabled, only left click fire "onclick" JavaScript event.
But, this option does not work on my environment. Is this option deleted on current release!? If so, I will be delete this option.
3] What does the function "Accept instance"
under "UI > Others > Accept instance (likely Mac or Gnome)"
First of all, "Accept instance" is typo. "Apply instance" is correct. I'll fix it.
When this option is enabled, the preference window apply immediately the user choices, without waiting for the window to close with "OK" button.
It is default behaviour of Mac and Gnome.
4] What does the function "Do Not check secure updates of add-ons"
under "Add-ons > [ ] Do Not check secure updates of add-ons"
This setting is for add-on authors.
Addon update link data must be a SSL-encrypted URL (https://) or signed. When this option is checked, this check is bypassed. See also:
