When you try to install add-ons, I tells me I have version 2 and upgrade.

For the past few months I have problems with Youtube or installation of extensions. In both cases, I get a message saying that I have an outdated browser (version 2) and must be updated. I installed Firefox 3 (lately 3.6.3) several times, closing of the old version of first each time. Firefox/subject shows that I have installed 3.6.3. I even tried completely remove the old version and download the new version with Safari (I saved my bookmarks, etc. in this case). Something is very wrong, and I'm unable to install several important extensions because of this problem.

I use a Mac, OSX 10.5.8.

I'm at my wits end. Does anyone have any suggestions?

This has happened

Each time Firefox opened

== I have installed version 3.

Your string UserAgent in Firefox is marred by another program you have installed.

type of topic: config in the URL bar and press ENTER.
If you see the warning, you can confirm that you want to access this page.

Preferences are "BOLD", a line at a time, and then select reset, right click
Then restart Firefox

  • When I try to install Add - ons it tells me I need Firefox, but I have Firefox Home already installed on my iPhone.

    I'm in a loop - I open Firefox Home and click on addons and get a pop-up telling me I have to install Firefox. By clicking on this link gives me a link to download Firefox Home. That is what it is?

    "Firefox Home" for iPhone is not a web browser. Firefox extensions are for Windows, Mac, Linux desktop versions of Firefox and some may work on the Android version.

    http://www.Mozilla.org/en-us/Mobile/Home/FAQ/

    Firefox Home is a free application that lets you have access to your Firefox desktop history, bookmarks and open tabs on your iPhone.
    

    Is this way Firefox will be available on the iPhone?

       No. We do not have plans to ship the full Firefox browser for the iPhone. Due to constraints with the OS environment and distribution, we cannot provide users Firefox for the iPhone.

  • Problems with Service Packs - when you try to install Service Pack 2, it says I have to install SP1. When I try to install SP1, it says that I have already.

    My automatic update did not work, so I went to the site to try to download Service Pack 2, one seemed to have trouble with my computer. After I downloaded it, I tried to run, but he said I had to download Service Pack 1. So I did it. When I try to run this file, it says I have already installed Service Pack 1. So I tried to restart the Service Pack 2, but she is always claiming that I need Service Pack 1. I don't know what I'm supposed to do. Can anyone help? I'd be happy.

  • When you try to install FSX it stops installing at halfway with the 1935 error code

    I run Windows 7 in the 32-bit version. When you try to install Flight Simulator X (who at one point does not work on my Win 7), facilities stop 1935 hal - way and gives error message. This is what shows on the small window:

    Error 1925. An error occurred during the installation of Assembly
    Microsoft VC80 ATL.type version = "8.0.50727.42" publicKey Token = .processorArchitecture ' 1fc8b 3b9a 1e 18th 3B "="x 86 ".

    Anyone an idea what I can do to fix this?

    Hi John,.

    Thanks for choosing Microsoft Community Forums.

    According to the description, it seems that you are having problems with the installation of Flight Simulator X game that you get an error message "error 1925. An error occurred during the installation of Assembly'.

    (1) did you do changes on the computer before this problem?

    If you receive a 1935 error when you try to install the software, the Windows file system transaction log is corrupted. The transaction log is used by the Windows file system to recover when a file error occurs. It can also occur if an error occurs with the installation of .NET Framework.

    Step 1: To correct this install error, you must clear the log.

    a. open an administrator command prompt: right click on start > all programs > Accessories > command prompt and select "Run as Administrator" and click "Allow" for the elevation prompt

    b. in the command prompt, type the following command:

    true fsutil resource setautoreset C:\

    c. which assumes that C: is the drive where Vista is installed. If it is installed on another drive as D:, please change the appropriate drive letter.

    d. restart the system.

    e. install the software and check.

    Step 2: I suggest you to place the computer in clean boot mode and check if the problem persists.
    A clean boot to check if startup item or services to third-party application is causing this issue.
