Java plugin doesn’t work in Firefox Portable
I need to access a corporate application that has a web interface and a Java applet.
I read that Firefox 52 and later don’t allow the Java plugin anymore. So I installed Firefox Portable 51.0.1 into C:\users\username\Downloads\Firefox_51.0.1_Portable\FirefoxPortable. Then I copied the FirefoxPortable.ini file from the Other\Source directory and put it in the same directory as FirefoxPortable.exe. I edited the file to have the following:
Then I read that Java 8u131 and later don’t allow MD5 signed jar files which the corporate application uses. So I installed the 32-bit version of JPortable 8u121 into C:\Users\username\Downloads\Firefox_51.0.1_Portable\CommonFiles\Java. (followed the instructions at https://portableapps.com/support/firefox_portable#plugins)
I launched FirefoxPortable.exe, and checked the Tools->Add-ons->Plugins, and I saw that it had the Java(TM) Platform SE 8 U121 plugin. Looks like I installed everything correctly.
But when I go to https://www.java.com/verify/ and click on «Verify Java Version» to make sure the Java plugin is working, it says «Detecting Java on your computer» and «The Java detection app will ask for permission to run. Click Run to allow the verification process to continue. Depending on your system settings, you may need to respond to prompts to allow the verification to continue.»
But it doesn’t prompt me at all. After about 2 minutes, it finally says:
«We are unable to verify if Java is currently installed and enabled in your browser.»
I also went into the Java Control Panel, to the Security tab, made sure «High» was selected, and then added «https://www.java.com/» into the Exception Site List, but that didn’t help.
EDIT: I got it working. Somehow the «Enable Java content in the browser» box wasn’t checked in the Security tab of the Java Control Panel, and also I needed to have the port number along with the URL in the Exception Site List.
Firefox Portable + Java + Flash
Что делаем: портабельный Firefox с включенными Flash и Java.
Зачем: управление старым оборудованием.
Установка Firefox Portable
Т.к. с версии 53 перестали поддерживаться старые версии плагинов (NPAPI), качаем с https://portableapps.com/apps/internet/firefox_portable версию 52.х (ESR). Разворачиваем куда-нибудь, например в X:\PortableApps\FirefoxPortable
Копируем файл X:\Portable\FirefoxPortableESR\Other\Source\FirefoxPortable.ini в директорию X:\PortableApps\FirefoxPortable — нужно будет сделать некоторое кол-во настроек.
Включение 32-битного Firefox
Т.к. старые плагины работают только в 32-х битном режиме — его нужно включить принудительно, т.к. в сборке идут обе версии. В файле FirefoxPortable.ini устанавливаем переменную AlwaysUse32Bit=true
Разрешение запуска Firefox Portable совместно с Firefox
Если хочется одновременно запустить Firefox Portable совместно с Firefox и появляется ошибка «Another instance of Firefox is already running. Please close other instances of Firefox before launching Mozilla Firefox, Portable Edition» или «Обнаружена активность другой копии приложения Firefox. Пожалуйста, закройте все копии Firefox перед запуском Mozilla Firefox, Portable Edition» — в файле FirefoxPortable.ini устанавливаем переменную AllowMultipleInstances=true
Установка Java
Качаем https://portableapps.com/apps/utilities/java_portable и разворачиваем в X:\PortableApps\CommonFiles\Java — в этом случае наш портабельный Firefox увидит Java и заработает.
Установка Flash
Для запуска Flash в браузерах можно установить https://ruffle.rs/#downloads — есть плагины для Google Chrome & Firefox, а так же самостоятельное приложение
Описанный на сайте способ установки Flash «это всего лишь расширение, скачайте и поставьте» отсюда: http://fpdownload.macromedia.com/get/flashplayer/xpi/current/flashplayer-win.xpi у меня не заработал, Firefox говорит «пакет поврежден, устанавливать не буду». Заработал предложенный на их форуме способ:
запустить FU-LASH.exe — он определит где находится, закроет его, удалит все установленные версии Flash, скачает и установит последнюю версию с сайта Adobe

Firefox Portable and Java Portable
How do I get Firefox Portable working with Java Portable? The upcoming version of Firefox, 3.6, will only support Java 6 Update 10 and upwards. I installed Java Portable, which is supposed to be Java 6 Update 17, to X:\portableapps\CommonFiles\Java as requested. My Firefox is installed to X:\portableapps\browser. When I load Firefox 3.6 Beta 4, it does not see Java Portable.
I don’t think Firefox supports Java portable, and I’m pretty sure it can’t (legally) support it. sorry.
«The question I would like to know, is the Ultimate Question of Life, the Universe and Everything. All we know about it is that the Answer is Forty-two, which is a little aggravating.»
Unfortunately, Firefox looks in the registry to see if java is available and the portable java (naturally) isnt listed there.

Firefox (both installed version and portable version) may use the environment variable «MOZ_PLUGIN_PATH» to search for plugins, so you can:
1) create a new environment variable in your OS using the above-mentioned name and put as value [current plugins folder];[portable java plugins folder]
2) simply create a batch file (.BAT file), using the «set» DOS command to set the above-mentioned environment variable in the same format:
set moz_plugin_path=[current plugins folder];[portable java plugins folder]
and then insert a new line to run Firefox.
3) using the .INI file of the portable firefox version to include the plugins folder of Portable Java.
The [current plugins folder] is the current folder of Firefox Plugins. If you don’t know where it is, open firefox, go to Plugins page, search for «default plugin», you can read the full path where the default firefox plugin is placed.
The [portable java plugins folder] is the current folder of plugins used by portable java. It is placed in «Java\bin\new_plugin» folder (Java is the root folder where Portable Java has been installed). If you still have problem, search for file «npjp2.dll», and take note of the related folder where it is placed.
To check if one of the above-mentioned procedure has gone well, open Firefox and you should have two new items inside Plugins page:
«Java Deployment Toolkit» and «Java Platform SE».
Hope this may be useful for all of you.
P.S. If you use the procedure 1, you must logoff Windows and logon Windows again in order to let Windows load the new environment variable.
