• I received a "popup" to update Firefox, it was ligit?

  I received this "popup" who said that I had to click to update Firefox, because "I am at risk." I didn't proceed/click because I thought that the updates are performed automatically. Should I have clicked on this "popup"?

  If you get a pop-up message asking to put plugins or Firefox updated or anti-malware analysis then this message probably is a scam and you should never respond to such reporting to avoid being infected by malware.

  • Don't update Firefox via "> about" or by downloading and installing Firefox from Mozilla and server never using a popup or a link on a web page.
  • Plugins should be updated only through the plugin itself, or by visiting the home page of the plugin.

• Should what settings I use to make a link to an email opens in Firefox and not Internet Explorer?

  Instead use a link on the MSN page to make your homepage, try to use one of the techniques in this article to support: How to set the home page.

  Some users have accidentally lost their home page and modules using the Refresh function during their update. This can happen when you see a prompt that Firefox is slow at the start and you can speed it up by restoring some default settings. If you click this button, your Firefox settings folder is moved to your desktop in a folder called old data from Firefox. Do you see something like that? If so, I suggest hanging for a few weeks, in the case where you notice something else missing. Feel free to ask questions about the rescue of the data in this folder.

• Why update firefox and got a 'free' bing search bar and two software malicious adware?

  After an automatic update - no, I do not download no matter what new version of any dangerous place - I found that I had the Bing search bar-which I think I've turned it off, not sure if - and two malware/adware problems. First was rvzr - a.akamaihd which arises a new tab when clicking first on a website, then I found that I had offerswizard adding banners - blocked most of them - and the creation of hiperlinks with mini pop ups when passed above it with the mouse - sorry if my English is not clear. I tried AVG free and there wasn't any warning. Finally, ad-block and rgiht, click on the arrow to search bing seems to fix the problem, however, offerswizard must be uninstalled manually - lightning enhance program, I think that - after a google search.
  The main question is... can I trust firefox download/upgrade to automatic update?

  Thank you all for your answers. I tried to mark it as resolved, but I doubt that I did.

  First I tried in windows / removal of unwanted software programs. Installed an adblocker for FF
  Then I downloaded the adware 3.8 removal tool and the problem is almost solved. Still a few details could be improved, but I can live with that.

  I think someone took advantage of the installation of FF and it makes any other malware on my computer.

  Thank you once again.

• Updated Firefox and now I Bing as the start page for Firefox browser. How to make Google return

  Updated Firefox 22 to 23 Firefox and now I Bing as my browser. I want Google as my browser. How to set Google as my browser on Firefox start page.

  I'm back and I solved the problem myself. That's what you have to do... (1) type in the search "topic: config ' and click 'ok' when warning is displayed; (type 2) to the research "browsers.search.selectedEngine" 3) now right-click on "browers.search.selectedEngine" and choose in the menu 'new' and now, choose "string" and just write 'Google' and click on 'ok '. She and your done. Now I have my trusty Google back as well as you. I was a little afraid at the beginning because I know if I make a mistake I would have maybe reinstall Firefox but everything worked very well and is very easy to do. Just make sure that you re - check before you click on 'ok '.

  Problems with bookmarks and history does not properly can be caused by a corrupted database places.sqlite file.
