Java and browser compatibility

I use Windows XP with IE8 (I do not well), Firefox, and Opera installed.

Java is set to notify me of an icon from the taskbar when an update is available, but do not download automatically - I have just updated to the latest version (Java 7 V. 73).

-When I go on ' Start, Java, Check for Updates ", it says I have the latest version.

-When I go to the Java website to check the latest version:

Use of IE-it confirms that I have the latest version

With the help of Opera,-he says that it is impossible to check if Java is installed and enabled

Using Firefox says Out of Date Java Versions were not uninstalled. »

I checked Add/Remove programs and only 8 V. 73 Java is installed.

1 Why Java confirms I have the latest version, but only the IE 8 browser recognizes?

2. given that Firefox and Opera cannot "detect", means that it is not operational in the two browsers?

You have several problems, starting with the fact that Windows XP has not been supported since April 2014 and so is severely outdated and vulnerable to attacks from malicious software.  In addition, Windows XP supports only Internet Explorer up to version 8.  IE is now at version 11.  So, you have also an out-of-date and vulnerable browser.

Those comments, there are many who recommend that Java may not be installed on your computer, no matter what operating system or browser, you can have.  See, for example

http://www.theguardian.com/technology/askjack/2013/Feb/08/Java-remove-ask-Jack-technology

http://www.PCWorld.com/article/262011/if_you_dont_really_need_java_get_rid_of_it.html

Unfortunately, you may need Java to the functioning of a web site you visit, such as your bank.

Because Java is so frequently attacked and nearly as frequently updated, it is advisable to remove older versions of Java.  You should have the ability to delete old versions when you installed Java SE 8 u73.

See http://java.com/en/download/faq/remove_olderversions.xml

Go here: http://java.com/en/download/uninstallapplet.jsp

That's what you should get if you only have the last version:

If there is an older version, you should get a list of those who have been detected and the possibility to uninstall.  Do.  If you don't have Version 8 update 73, but still get the notice that "Out of Date Java Versions were not uninstalled', I suggest you uninstall completely Java Control Panel > Add / Remove Programs, reboot and start again.

As for Firefox, you can check that it uses.  Open Firefox and type about: addons in the address bar and click on Plugins in the left pane.  Scroll down and see which version of the Java plugin is installed:

Opera works similar to Firefox.  See http://help.opera.com/Windows/11.60/en/extensions.html or http://www.tomsguide.com/faq/id-2374762/manage-extensions-opera.html

  • Browser compatibility issues: Table wide and glitter animation autoscroll

    Hi guys

    I just uploaded a site in BRUTE form, just so that I have an example to show you. I'll probably take it down once I have a solution. I tested it on IE and chrome, the two latest versions (I think)

    The site is: www.jpmediaonline.co.uk

    OK, I have 2 questions, both are specific browser

    1. the table in the accommodation section is much wider in IE than chrome. It is intended to be displayed in the width, is it in Chrome.

    2. I use a JSquery to autoscroll and animate between sections. It's perfect on IE, but apparently on chrome Jutters / glitch / flicker... it seems to happen just as the accommodation section is about to pass.

    Hope I can get help to these two questions.

    Thank you!

    While your DIV class to "hostingtable" has a "width" defined for it, your table in itself is not.

    Add a "width" tag to your class 'table1' and set it to your desired width. IE will read the width of the table and show exactly that much.

    About the scrolling of the page, I don't see any glitch / twinkle / Jutters. Even if you see it, I suspect something to be with the settings of your video card that Chrome is programmed for. This should not be a cause for concern as a "browser compatibility".

    I hope I'm posting in the right place. If this isn't the case, please let me know.
    My office is a Dell Dimension. I got it in 2002. It has Windows XP SP3 and IE6.0 SP3 with all updates. MS Java Virtual Machine was part of XP or IE and is always there because I find because it is on the page of advanced Internet Explorer properties. I don't have any other installed Java (nothing in program configuration panel). I want to go to the Intel driver support website and download their program to detect the Intel drivers on this system and download if necessary. The site says I need to download the latest version of Java. I understand that. Here's the question:

    Is there something I need to do before you download and install the latest version of Java? I have a Java in C:\Windows folder, but nothing in C:\Program Files. He has a key to JavaSoft under HK_LOCAL_MACHINE\Software, but there is no value set for the key. There is no a JavaSoft under HK_LOCAL_USER\Software key.

    And I did not update that is to say, other than the buggy reported all over these boards, it's because I only use IE to windows update. My default browser is Firefox.
    Thanks for any help.

    You can download Java from www.java.com you don't need to do something special for your PC ready for Java, and it is safe to run. If you encounter installation problems, or you get the latest version installed according to the Java website and the Dell Web site has always that you need a current version let us know. We can help you with that.

    I think that you are in the right forum. I'm not a moderator or anything either, but it seems OK for me.

  • Problem of browser compatibility with CSS in DW opacity

    Hello... I am very new to Dreamweaver, (fresh outta several years of photoshop) try to learn it and have very little experience with HTML/CSS coding. I'm doing a translucent black rectangle (drawn using CSS instead of using an image of a black rectangle) which is over a plaid background (background image of the tag body with background repeat.)

    In order to get this black box as transparent semi, I searched the web and found that I needed to use the Opacity property in the CSS (makes sense to me). So I hand coded because Dreamweaver didn't "opacity" as one options in the small drop down menu deal. After I did it, Dreamweaver has me in the "Browser compatibility" Panel that the 'Opacity' property was incompatible with virtually all browsers, including Firefox, Safari and Opera (mac guy). Not only that, but my black box was not translucent in the 'Design' of the preview window thing.

    Just for fun, I decided to open the page in Firefox - AND IT WORKED. He showed my black rectangle like I wanted, stretched and the ADJUSTMENT of the opacity that I wanted. I opened it in Opera and Safari, which also displays my page as I wanted.

    My questions are the following:

    1 - Why is Dreamweaver saying this opacity setting will not work with these browsers when it actually does?

    2-Why don't show up in the 'Design' preview opacity setting window but don't place in real browsers?

    3 - Why is opacity not one of the features that descends when coding (like width, height, margin etc..)

    In any way, please don't hate not me I'm so freakin new and I tried to search this forum and on the internet for the answer to my question and found nothing. My code is below:

    The HTML code:

    < ! DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional / / IN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" > ""
    " < html xmlns =" http://www.w3.org/1999/xhtml ">
    < head >
    < meta http-equiv = "Content-Type" content = text/html"; Charset = UTF-8 "/ >"
    < title > Tim Moen | < /Title > Designer
    < link href = "styles/tim_moen_designer.css" rel = "stylesheet" type = "text/css" / > "
    < / head >

    < body >
    < div id = "black" > < / div >
    < / body >

    < / html >

    THE CSS:

    @charset "UTF-8";
    / * CSS document * /.

    {body
    background-image: url (.. / images/burberry_dark_pattern.gif);
    background-repeat: repeat;
    background-color: #000;
    margin: 0 auto;


    }

    {#black}
    top of the margin: 20%;
    background-color: #000;
    height: 400px;
    opacity:. 8;

    }

    There are dozens of CSS attributes that can (and should) be handwritten. Problem with them is that, as shadows of text, they do not appear in all browsers. I have 9 different browsers installed and test pages in EACH of them before I "Finish" site or a page of a model construction.

    I try to compile for Firefox, personal preference, but I do things that work with IE because he still holds the market share (46% to 42% FF IE), and I'll only with designs that work in IE, FF, NS, Opera, Safari and Chrome.

    As for your questions.

    1. the verification of compatibility is probably common at the time of construction. I do not know if this item updates such as browsers, but I tend to think that it isn't. I use CS4 and there have not been updated for it in almost a year. Firefox has released 4.0, published 11 Opera and Safari 5 has released since then. The update would have found and downloaded something if it were available.

    2. I could only guess. Text shadows do not appear in Design view (or IE) but they do in the browser preview. It's just a quirk of the user interface, which means 'trial and error' is the only way to get what you want.

    3. Quick Access - selects which are located in the drop-down menus DW or popouts is the most common CSS designs and have been proven to work with all browsers at the time of your particular of DW build.

    Hope that helps...

  • Link to the style sheet is a mistake when checking for browser compatibility?

    Please give me a hand, when I check the browser compatibility in my Microsoft4 site that I am building in cs4 can. The only error I get is a reference to line 8... and the link to my stylesheet is highlighted? as an error? I don't know why? The site looks fine when you preview in safari and firefox, but not ie...

    Any solution would be greatly appreciated.

    Hello

    The error is in the line of this css rule font-

    #wrapper #subscribe #form1 label {}

    do-family: "Lucida Sans Unicode", "Lucida Grande", without serif.
    do-size: 12px;
    make-weight: lighter;

    }

    Your username using values such as lighter or bolder is not recognized by some browsers, and when they are they normally apply an unknown value depending on the browser that has.

    I checked the updates of plugins Firefox 24 and it showed that I needed to update Java and VLC media player even though I knew I had the latest versions. I ran FF update for both links and rebooted but still said that both need to update after a new analysis. I uninstalled both programs then re-installed the latest versions. FF always says I have v2.06 VLC and I 'vulnerable' but the VLC software shows that I have v2.08 which is the last. Java is now properly recognized and are more marked as in need of update. How can I get FF to recognize that I have the latest version of VLC? Thank you.
