XP 32 FF 17.0.1 bug, chrome+ FF js error, mutation events should be mutation observers

  • No replies
  • 9 have this problem

Recently updated FF to 17.01, now can't send emails with Thunderbird, in the error log are two warnings: Chrome://messenger/content/msgMail3PanelWndows.js Instead of Mutation events use Mutation Observers Chrome://messenger/content/about-support/gfx.js

I tried Chrome but uninstalled it, because I wasn't content with it. I also unistalled and reinstalled FF 17.0.1, but Chrome still affects the system and causes a js error so that the sending of the email is stopped and FF stops working. The operator's server stops loading the page because of timeout.

The bug also affects the IE 8, the error description is: IE cannot load this page, because of js error
