• tabs disappear whenever I start Firefox 19

  I normally Firefox put in place to have 5 tabs pinned and 2 or 3 tabs recorded since the previous session of Firefox. Since I have updated to version 19 FF, I lose 1 pinned tab whenever FF is started. I tried the fixes suggested on the issue of corruption of sessionstore.js file, checked to make sure that Firefox 'Will Remember history' is selected, the file used > Exit to leave FF. Whenever I start Firefox, it will miss a pinned tab (not all, just one). I started with 5 and I can go out, and then launch FF and only 4 pinned tabs are open. Repeat and only 3 are open, etc. If I have a normal tab open when I go out, it is saved & opens the next time FF starts, it seems open tabs is saved, but pinned tabs are closed. In addition, it is always the second pinned tab which is lost (counting from left to right). When there is only one tab left, pinned next time I restart FF, a normal tab is closed. Every time you start after that will close another normal tab until one pinned tab is on the left (the left most pinned tab). I have not tried to restart FF with only the one pinned tab, but essentially is that I lose 1 tablet recorded each time I have quit and restart and seq. anyone else see this behavior or have any suggestions to fix?

  If the home page button works fine, but your shortcut on the desktop to send you to the wrong page, the shortcut can be hacked.

  Right click on the shortcut icon > properties > Shortcut tab

  For Windows XP (default location), the goal should be either not less that what follows. If there are extra things, empty:

  "C:\Program Files\Mozilla Firefox\firefox.exe"

  If that checks well, hmm, I wonder if you could have a hidden extension? Extensions are unable to hide mode without failure of Firefox.

  You can restart Firefox in Mode safe mode using either:

  • button "3-bar" menu > "?" button > restart with disabled modules
  • Help menu > restart with disabled modules

  Not all add-ons are disabled: Flash and other plugins still works

  After stops in Firefox, a small dialog box should appear. Click on 'Start mode safe' (not reset).

  Any difference? Also, you can visit the page modules. Either:

  • CTRL + SHIFT + a
  • "3-bar" menu button (or tools) > Add-ons

  In the left column, click Extensions. Then see if something new appears at the time where you posted from your list:

  • 160by2 1.2 ([email protected])

• How can I stop the bad website to come whenever I start Firefox?

  After installing some software, the URL "http://hi.ru/?10" guard opening in a new tab, whenever I run Firefox. He also took over my home page in Chrome and IE, but it was easy to fix those. For some reason, he keeps ignoring the homepage that I changed it to my Firefox settings. It keeps just setting up this stupid Russian Web site. I tried searching in: config but nothing there. I looked for Add-ons, but nothing is there. No toolbar that could do it too.

  It is not similar to the problem discussed in this article, but I use Windows 8.1, so is not a simple shortcut that I can change.

  If your homepage is correct in the Options dialog box, but by clicking on the icon of the House or by opening a new window (Ctrl + n) charge the wrong page, or charge two tabs (a right, an evil)?

  I know that you have verified that many of these things before, but if you wouldn't mind taking a second look:

  (1) starts by the Control Panel, uninstall a program. After the loading of the list, click on the column heading "installed on" to group infections, I mean additions by date. This can help the undisclosed items bundle smoker who snuck out with some software, you have agreed to install. Out as much garbage as possible here.

  (2) then, in Firefox, open the page modules using either:

  • CTRL + SHIFT + a
  • "3-bar" menu button (or tools) > Add-ons

  In the left column, click on Plugins. Set essential and unrecognized plugins 'never enable '.

  In the left column, click Extensions. Then, in case of doubt, disable (or delete, if possible) not recognized and unwanted extensions.

  Often, 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.

  If the problem only occurs with the shortcut on the desktop, are looking for a hijacked 'target' using the side Windows desktop. Right-click on the icon, choose Properties and then the shortcut tab. If you've pinned to the taskbar, the icon of Firefox there is an extra click: right-click on the icon and then click Mozilla Firefox. Then you can get real estate.

  The 'target' for Windows 7 32 bit should be either not less the following:

  "C:\Program Files\Mozilla Firefox\firefox.exe"

  Edit: Sorry, I forgot to edit after pasting...

  The 'target' for Windows 64 - bit 8.x must be not more not less the following:

  "C:\Program Files (x86)\Mozilla Firefox\firefox.exe"
  

  If there are extra things on the line after that, it empty.

  Any progress?

• Get the message that my vidio player is outdated. I tried 7 times and he always invites whenever I start Firefox.

  I think you have malware. Start by removing the MediaPlayer extension, restart Firefox and see if the problem goes away. Then I suggest to also review the control panel to the other group junk that can infect Firefox or cause other problems. Here's how:

  (1) open Firefox page modules using either:

  • CTRL + SHIFT + a
  • "3-bar" menu button (or tools) > Add-ons
  • in the Windows "Run" dialog box, type or paste
    firefox.exe "about:addons"

  In the left column, click Extensions. Then find and remove the extension is suspected.

  Often, a link will appear above a removed extension to restart Firefox so that it comes into force. You can complete your work on the tab and click one of the links in the last step.

  (2) open the Control Panel, uninstall a program. After the loading of the list, click on the column heading "installed on" to group infections, I mean additions by date. This can help the surface elements undisclosed bundle which snuck out with some software, you have agreed to install. Beware of everything that you don't recognize / remember, since malware often uses sounding names important or innocent to discourage you remove. Out as much garbage as possible here.

  (3) for greater peace of mind, you can search for possible problems with the scanning/cleaning of the tools listed in our technical support article: Troubleshooting Firefox problems caused by malware. These scanners on request are free and take a long time to run. If they end quickly, especially if they require the payment you have a serious infection. I suggest the specialty forums listed in the article in this case.

• Time Warner has ordered me to use an IP address directly in the address bar, now I can't stop Firefox try to contact this address whenever I start Firefox.

  I was sent a new modem/wireless router by Time Warner in their package of socalled EASYCONNECT connection. They instruct me to search for my current network settings by putting a numeric IP address in the browser's address bar. This IP address could not be contacted, but this isn't the problem:

  Now, whenever I run FIrefox, a tab opens and the browser tries, each time without success, to contact this IP address. I want to STOP this, simply return to what the regular homepage from Firefox / Google invites with NO PRELOADED in the address bar.

  Can someone please tell me what to do? I tried a "reset" of the home page. I can't find this call my story, even if it is perhaps here.

  You can use the SearchReset extension to reset preferences to default values.
