Manually linking the Java plugin libraries to the Mozilla plugins directory may cause the Firefox browser to crash on Linux during startup, due to incompatibilities with 'glibc' versions in JDK 8u191 and later releases. The crash might also occur if the link was manually created for an earlier JRE and a user updates to JDK 8u191 or later releases. For more information, see the Known Issues section of the JDK 8u191 release notes.
When you install the Java platform, the Java plugin file is included as part of that install. If you want to use Java within Firefox, you need to manually create a symbolic link from the plugin file in the release to one of the locations that Firefox expects. To make the plugin available to all users, create the link inside of the Firefox application's directory, in the plugins subdirectory. Alternatively, you can create the symbolic link in your home directory, in /.mozilla/plugins. In the remainder of this document, the text, "Firefox plugins directory", implies either of these locations.
Install Java Plugin Firefox Portable Version
Only one Java Plugin can be used at a time. When you want to use a different plugin, or version of a plugin, remove the symbolic links to any other versions and create a fresh symbolic link to the new one.
This all works fine, with the slight exception of the Flash Player plugin. Adobe doesn't do portable. Neither the Flash Player installer nor the uninstaller is the least bit aware of, or concerned with, portable versions of Firefox.
A few days ago, when I updated my desktop computer to the latest version of the Flash player, it didn't take. Although the Flash Player installer ran fine, my portable copy of Firefox kept using the old version, according to the Adobe Flash tester page.
But, I had run a normal Secunia scan rather than a "thorough" scan. The normal scan looks for applications in their normal location. Anyone using a portable application needs to use the "thorough" option when scanning with Secunia for old software. A thorough scan showed that the portable version of Firefox was indeed still using the older software.
If, as in my case, the computer has the latest copy of the Flash Player on the C disk, copying the appropriate DLL from the C disk to the X disk will get the portable Firefox using the latest version of Flash.
Specifically, copy file NPSWF32.dll from C:\WINDOWS\system32\Macromed\Flashto X:\FirefoxPortable\App\firefox\plugins. The full path for your portable copy of Firefox will be different, but wherever it resides, copy the Flash Player DLL into the \App\firefox\plugins folder. Again, a "thorough" Secunia scan will point you to the right place.
If the computer in question doesn't have a normally installed copy of Firefox, then simply delete or rename the file with the old version of the Flash Player (Secunia will find it). The next time you visit a web page that needs Flash, such as the Adobe Flash tester page, Firefox will prompt you to install the missing plugin and you'll get the latest version.
Finally, be aware that a portable copy of Firefox that doesn't have it's own installed version of the Flash Player will pick up a copy from the C disk, if a normally installed copy of Firefox exists. But, if the portable Firefox has an old version of Flash in its plugin folder, it will use that even if a newer version of Flash is on the C disk - which is what prompted this posting in the first place.
Many players are using other browser than Firefox, other players are already using Firefox but the new versions are not supporting NPAPI plugins in any way and they can't have more than one Firefox installation on their PC. For that reason we are going to be using an older Portable Firefox version.Portable apps are not being installed and they can work even on a USB Flash Drive.Therefore we will use Mozilla Firefox 52.9.0 ESR, Portable Edition. This is the last Firefox version which can run Java plugin for browser.
The portable installation is coming with 32bit and 64bit Firefox versions. You NEED to run the 32bit version, 64bit won't work !For that reason open the FirefoxPortable.ini file in the
Download Java plugin for browser from the official website.Note : you need to download 32bit Java version. The official website is detecting whether your browser is 32bit or 64bit and you get a download link accordingly. That means you need to make your browser 32bit first.In case you can't handle it, here is an extra link where you can manually download the Java plugin. The first 2 links are for 32bit version download. Link
Something you can do is run two different flavors of Firefox on the same computer, one being an installed version and another portable version which you can perhaps use for work or to keep using your favorite extensions such as ArchView which no longer work etc. You cannot however, simply start one Firefox and then open another different version. When one Firefox.exe process is running, launching another will simply open a new window and not launch a different Firefox.
Fortunately Firefox does support running multiple instances with the help of a few simple modifications. There are a couple of ways to acquire a portable Firefox and they both need to be configured differently to allow an installed version and a portable version to work together.
An easy and popular solution is to use the portable version packed and distributed by PortableApps.com with the advantage being it is already setup to use a portable profile. You have to make a small change to allow the portable and your installed Firefox to run side by side, or the following error will popup:
3. Right click on the Firefox setup installer and extract to the folder of your choice. Starting from version 4, all files are stored in the Core folder. For 3.6 and below you need to copy the contents of the Localized folder into Non-Localized to get a portable version to work.
what I did was install flash on my pc to internet explorer 7 , that put the flash filesin system 32 folder.Then after that I found I had to put the whole macromedia folder into Firefox plugin folder.Then the flash worked and i Could watch videos in the portable Firefox.If you get the latest flash installed on any browser in windows , just copy macromedia folderthat is in system 32 folder, and paste into portable Firefox plugin folder.I dont think you can update because flash installer will not find the portable browser,only the installed browsers.It might if you put portable Firefox plugin folder into C:program files, might have to try that.
jPortable (formerly Java Portable) allows you to easily add a Java runtime environment to your portable device. It can be used in combination with jPortable Launcher to open Java JAR programs (many with their settings made portable) or used automatically with Java-enabled apps like PortableApps.com versions of LibreOffice and OpenOffice as well as web browsers like Chrome/Chromium, Opera, SeaMonkey and Firefox.
I needed to connect to an onion site and downloaded the latest version (5.0.2) but Australis makes Tor Browser absolutely terrible and unusable- I do not want to install heaps of add-ons just to restore features the Mozilla idiots removed. I had an earlier version of Tor Browser (3.6.0- before the advent of the abominable Australis) but the perpetual blinking of the Tor button urging for update is unbearable and cannot be disabled. It can be removed from the tool-bar but this way one cannot acquire new identities.
Starting from version 8.0 Tor project builds both version of TorBrowser: 32 bit and 64 bit.- TorBrowser page: - TorBrowser repository: So You can add on description the link for download 64 bit version 'torbrowser-install-win64-8.0.1_en-US.exe'
WebBrowserPassView is a password recovery tool that reveals the passwords stored by Internet Explorer, Firefox-based and Chromium-based Web browsers. This tool can be used to recover your lost/forgotten password of any website, including popular Web sites, like Facebook, Yahoo, Google, and GMail, as long as the password is stored by your Web Browser.Currently, WebBrowserPassView cannot retrieve the passwords if they are encrypted with a master password.To work with Chrome and Opera portable versions, go to 'options' and set the location of the portable browser folder. Select the user data folder in Chrome, and wand.dat for Opera. (Thanks to user "deer".)
The good side of this setup is that it allows running eBS forms of 64-bit Windows (I tried Vista, but I guess the same would work on XP as well) and does not prevent us from having newer java versions on the same machine.The bad side - we have to use several installations of firefox - each for a different purpose and the settings of plugin.scan.SunJRE=9.9 and alike are global across of all firefox intallations on the machine, so it means if you have another browser installation for latest JRE, you have to copy the NP*.dll to the firefox plugins directory each time you upgrade the JRE.
The toolchain itself is built on top of a customized version of GCC and GNU binutils that implement the constraints of the NaCl sandbox. Thus re-compilation is necessary, even for the "existing software components" and "legacy applications" use cases. The NaCl plugin provides a C library customized from NewLib.
Selenium is a portable software testing framework for web applications. The tests can be written with a Firefox plugin. The plugin records all your steps and afterwards integrates it into a testcase. The tests can also be written in several programming languages. 2ff7e9595c
