• When I opened every night all I get is a small black window that says close firefox

  Every night, I installed on a laptop with Windows 7. I used for almost a year. This afternoon, when I tried to open every night, I didn't get was a small black window, saying "close firefox." I used Chrome to get on the web, downloaded the latest Nightly and tried to open it. Same thing happened. How do I return every night?

  A particular reason that you use the Nightly version (sometimes unstable) , rather than a stable version of Firefox?

  Every night is not intended to be 'used', but rather for users help the developers of Mozilla by each new generation of 'testing' and then to report any bug or 'glitches' they can find. Every night is between 12 and 18 weeks of the release of a new version of Firefox - phase Alpha 1, which is 6 weeks.

• Firefox 8 puts new tabs opened from links in another tab at the end of the list, NOT next to the tab it just as in V3.6. I want it next to the tab that it comes. How can I do this?

  Question as noted, sums it up. When I click on the mousewheel on a link in a tab, for I want a new tab open with that link and want it beside the tab, I clicked on the link in any as Firefox V3.6 has done. Firefox 8 is always open the new tab at the end of the list and boy is that embarrassing!

  Please tell me how to solve this problem.

  Define the Boolean browser.tabs.insertRelatedAfterCurrent true pref on the topic: config page.

  To open the topic: config page, type Subject: config in the address bar (address) and press the 'Enter' key, as you type the url of a Web site to open a Web site.
  
  If you see a warning then you can confirm that you want to access this page.

  • Use the filter at the top bar of the on: page config to more easily spot a preference.
  • Preferences that have changed also show "BOLD" (user set).
  • Preferences can be reset to the default value using the context menu if they are set of users
  • Preferences can be changed via the context menu: Edit (string or integer) or toggle (Boolean)

• When you try to start Firefox I get a message saying "a copy of Firefox is already open. Only one copy of Firefox can be open at a time. "I started a new profile, but the Profile Manager always tells me that by default it is still in use.

  When you try to start Firefox, even once, I got a message saying "close Firefox. A copy of Firefox is already open. Only one copy of Firefox can be open at a time. "This issue is addressed in Mozillazine but nothing I've tried there seems to work. I started a new profile in the profile manager that gets at least upwards and the functioning, but strangely enough the Manager also told me the old (default) profile is still underway, although I can't find a way to close it. Also, I can't find the default profile in my Profile Manager. can anyone help?

  == I thought that I had left Firefox and he was new.

  I get the same problem from time to time. It is not a solution but I go into Task Manager (select by right clicking on an empty area of the start bar) and under the research process and, invariably, there is a 'hidden' version to use the FF. I selects & close via Task Manager and then am able to restart FF.

• Error closing firefox message appears at the start of the application and indicates that the copy of firefox is already open. How can I find the copy open and close all the time?

  When I consider my daughter and you try to start Firefox (she was previously using Safari) an error message is displayed stating to "close Firefox: a copy of Firefox is already open." Only one copy of Firefox can be open at a time. "Except that I don't see a free application copy, unless it is somehow launched during the connection, a framework I am not either. Firefox works fine on other user accounts.

  Is there still a current default profile folder?

  • < User > /users//Library/Application Support / Firefox/Profiles/< profile >.

  If not, then delete the file profiles.ini
  
  Which will cause Firefox to create a new default profile.

• When I close FireFox the story line fades to restart firefox. What is?

  Since the upgrade to 7.0.1 history on the url line does not keep the URL history for the next session. I even down loaded and reinstalled this version to see if it would work. Nothing helps. It is a pain by typing in URLS often used.
  Thanks for any information.

  Make sure that you do not have to erase recent history to clear the browsing history when you close Firefox.

  • https://support.Mozilla.com/kb/clear+recent+history

  Make sure that you are not Firefox running in permanent private browsing mode.

  • https://support.Mozilla.com/kb/private+browsing

  One possible cause is a problem with the places.sqlite file that stores the bookmarks and history.

• Firefox does not open. Cannot update or delete. Says it is already open and I can't find how to close it.

  Firefox shows that it is already open and must be closed in order to update or delete. I can't locate a place to complete the process. It's probably something very simple, but I'm not a computer genius. Thank you!

  Have you tried you look for firefox.exe in the Task Manager process tab (you can get to that by using Ctrl-Alt-Delete, usually)? If you click firefox.exe in the list and then click on end process, it should close Firefox, even if Firefox does not seem to be running (sometimes the process takes a little longer to close the main window). If all else fails, maybe a reboot?

• Then, Firefox crashes when I try to reopen, I get a message saying that it is already open and must be closed. It is not open and I can't shut it down and have to restart. It is very annoying, as often happens.

  Firefox closes unexpectedly so when I try to open it I get a message saying that it is already open and I first need to close. I can't find it anywhere open and then I have to restart to open Firefox again.

• Flash player 16.0.0.296 says now but will not fully updated unless firefox is closed, but when I close firefox that he says again that he needs updated. Why?

  my plugin update checker has been working well, so I know this isn't the problem. the problem is that when I update my flash player id stops at 95% or 96% and will remain like that until I close firefox and when I close firefox it then finishes update, but then what fierfox reopens it says he has again updated. I've never had this problem before so why now?

  Here is a screenshot and see the screenshot just copy and past this link http://i.imgur.com/MafjKdn.png

  Hello courtney-jane16, the result of the plugin check page unforunatley is correct, there was yet another vulnerability discovered in adobe flash player 16.0.0.296 who is already exploited in the wild.
  See the Security Advisory: https://helpx.adobe.com/security/products/flash-player/apsa15-02.html

  There is no difficulty because it published by adobe again and the button to update the plugin check site lead nowhere at the moment - so it's best to put the flash shockwave ask to activate plugin in firefox addons > plugins Panel!
