• When I run firefox v42 mac, the Preferences tab load as well

  When I run Firefox version Mac 42 on Mountain Lion, my homepage loads perfectly, but another 'Préférences' tab always seems to load as well. How can I stop this other tab from loading? Thank you, Ken.

  Hi Ken, one of the possible reasons are if the preferences page has been added as a second 'Home tab' in which case it will be displayed in each new window (Cmd + n) and every time that you click the Home button.

  To verify that you can use the preferences, the general Board, the section to start page, as described in this article: start-up, homepage, tabs and download settings.

  In the area of the Home Page, look for a vertical bar separating two addresses of character. A simple example with short URLS:

  https://www.mozilla.org/|about:preferences
  

  The bar certainly can be hard to spot with long URLs, but when you find it, delete everything to the right of the bar, then the bar itself (I suggest to remove the last bar so things don't accidentally get it together).

• When I run Firefox, it opens a tab hidden in addition to any home page I put.

  When I run Firefox by clicking on the icon in my toolbar Quick Start on wallpaper, it will open in any window, I put on the general tab of the menu options. But, there is an icon in the upper left corner of Firefox, if I click on it it shows this cartoon "http://images.dailykos.com/images/163050/lightbox/9-6-strip-KOS.png?1441645357."

  It is a cartoon that I looked at a few days ago.
  

  If I close the open tab by clicking on the x.
  the cartoon appears. I cannot delete it, do not know where it is registered, but it disappears when I close Firefox itself.
  It's all on a computer still under XP so what counts.
  I searched a file "user.js" on C: but not here.

  Maybe unrelated, but I can't delete unwanted Add-ins and extensions either.

  It's weird.

  What do you see if you right click on this icon?

  You run Kaspersky, correct? If you use the SSL scanning feature, Firefox must be put in place to approve the present Kaspersky false certificate to decrypt your secure connections. If you used the discount during the last update function - for example, Firefox says it's a bad performance and offers to restore some default settings - you have to do it again the installer of Kaspersky/Firefox.

• Dear all, I can not play the flash videos from any website through firefox because it freezes, but when I run firefox as administrator, then it works fine (but Google Chrome plays all the videos normally.). I use Windows 7 & Firefox 7.0.1. Help, pleas

  Dear all,
  Firefox crashes when I try to play flash videos from any website, but when I run firefox as administrator, it works very well. (but Google Chrome, Opera & I.E9 video parts without administrator.) I use Windows 7 & Firefox 7.0.1. Help, please.

  One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

  Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

• Why do I get three windows when I open Firefox instead of the unique homepage, I had put in place?

  I used to get a single tab, my Google homepage when I launched Firefox. Then one day I downloaded Google Chrome because I had trouble running an application. After that, when I launch Firefox, I get three tabs, a Gmail, a Home Page of Google and a browser that reads chrome://browser/content/newtab/newTab.xul - also, I get spammed like crazy and I was not before. I have my active spam blocker. I also downloaded a few flip something because I fell for the pop-up ad that said it would speed up my download speed. I have since uninstalled Google Chrome and I thought the flip thing, but I still get three launch windows and too many spam.

  Strange, since Google shouldn't do that. Maybe it was an installer bundled masquerading as official?

  To start your cleaning efforts, please check your home page settings. Do you get the 3 tabs when you press command + n to start a new window? If so, the additional URLS can be added to your home page in the Preferences dialog box. These articles describe where to find that. Notes that it can be difficult to see all the details of this area due to the limited space available, so often it is easier to delete everything and paste the desired URL.

  • Startup, homepage, tabs and download settings
  • How to set the home page

  Then please check your extensions, as they can override your settings. I suggest disable all non-essential or unrecognized extensions on page modules. Either:

  • Command + shift + a
  • Tools menu > Modules

  In the left column, click Extensions. Then, when in doubt, turn off. (Or so obviously bad, delete).

  Typically, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.
