Hello cumulus, indeed a new profile helps sometimes and it is great to solve the problem with a new profile.

see (if you have not already) : Recovering important data from an old profile

thank you

Hi cumulus,
sorry you have had a problem.

It is good to know it is fixed. Had you posted here first you would almost certainly have fixed your issue without loosing bookmarks.

Everyone's profile is different it contains the individual users settings

• see Profile Manager - Create, remove or switch Firefox profiles

Using a new profile may well be one fix for some such problems although it is the proverbial sledgehammer and nut approach. There is a long thread about this that I recently locked as it was getting totally unreadable.

• Warning: Unresponsive Plugin; Shockwave flash may be busy, or it may have stopped responding. /questions/957423
  • The Firefox Reset one popular solutions removes most of the profile
  • A clean reinstall could optionally remove the Firefox Profile
  • Other solutions and topics are linked from that thread.
• Creating a new profile and trying using that would have been a better suggestion
  Profile Manager - Create, remove or switch Firefox profiles

This sort of problem can have more than one cause. If removing the profile solves the issue then a less drastic method that almost certainly would work is to create and use a new profile and use that without destroying the original profile. (Copy the original profile elsewhere)

• see Back up and restore information in Firefox profiles

It is highly likely that only part of the profile causes the problem.

• Recovering important data from an old profile

As noted in the other thread this forum is not a place where you will get developer attention.

Do you have the Profile Bug ?

OR Unresponsive Plugin Problem, with FlashPlayer

If there is a profile bug then a bug report may be filed for developers attention, and the first stage of doing that is to be able to carefully document steps to reproduce the problem

• . So anyone blowing away the profile should first of all back it up
  • Being able to reinstall the faulty profile should then reproduce the problem and so demonstrate clearly that the profile is the cause of the problem
    Or just use the profile manager to switch profiles it is simpler and quicker
  • Next even before considering filing a bug try reinstalling or activating different parts of the profile to narrow down the problem.

For anyone seeing the dialog box, "Warning: Unresponsive plugin. Shockwave flash may be busy, or it may have stopped responding"

Before you create a new profile (or reset Firefox) and before you ask a new question, please read this article:

Warning Unresponsive plugin - What it means and how to fix it

Sure, try the less disruptive mechanisms first. But if they don't work, as they DID NOT for me: 1) Rename/move your mangled profile (courtesy of unknown or ignored bad Firefox behavior) so that it is out of the way - in other words, effectively deleted. You can also simply delete the profile. 2) Then create a new profile 3) Optional: If you saved the bad profile, try to send it to Mozilla so they can find and fix their bug

To locate the bad profile file, follow directions in https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data?redirectlocale=en-US&redirectslug=Profiles

_{Note from moderator: "Rename/move your Profile" is not the same as deleting it as you still have access to files in the Profile particularly things like the bookmarks. Also, if you wish to rename or move your profile and automatically create a new default profile, the folder to rename or move is the Firefox folder that contains the profiles.ini file. See the Profiles article for its location.}

cumulus, I'm marking your answer as the solution as far as this thread is concerned, since it worked for you.

Rename/move your Profile is not the same as deleting it as you still have access to files in the Profile particularly things like the bookmarks.

Thanks, James. I edited the "solution" with that information, plus details on how to automatically create a new default profile by moving or renaming the Firefox folder located in the profile path. Ref: http://kb.mozillazine.org/Creating_a_new_default_profile
