Java plugin deprecated in Java9

With Java9 the java web plugin will be discontinued. Browsers like Microsoft Edge are removing plugin support, so this is a logical step.
Java's origins are in embedded execution, running applets in the browser, using the plugin.
Oracle has a whitepaper with migration options.

Firefox on windows 64 bit : use the 32 bit plugins

When installing the java plugin on windows 64 bit (I have windows 7), which Java plugin do I need?
64 bit seems the logical choice.
Here's what Oracle, steward of Java says at this time:

Java for 64-bit browsers

Users should download 64-bit Java software, if they are running 64-bit browsers.

Allright, now do I have a 64 bit firefox, the page tells me how to check

Verify if you are using 32-bit or 64-bit browser

Firefox

To determine whether you are running on a 64-bit version of Firefox, use either of these methods.

• Check the About Firefox panel
• Type in the browser address about:support

If you are running 64-bit Firefox, it may be indicated as 64-bit (e.g., Win64); otherwise it is a 32-bit version of Firefox.  

 What can I find on this page?

 User Agent     Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0

There's a number 64 in there, but take care: this indicates that windows is 64 bit. To really know more about your firefox you need to follow the about:buildconfig link. oracle should recommend to type that one directly. Look at the target entry:

target i686-pc-mingw32

This is a 32 bit build after all. As a matter of fact, Firefox does currrently not provides a production quality 64 bit build for Windows. On Windows, Firefox currently is a 32 bit application, hence you always take the 32 bit plugins.

Firefox plugin: split browser

Allows yout to have a Norton commander like multi pane browser. Handy when you're having to work on one page with data from another page.
I'm still missing tabs in the other panes, but otherwise another great firefox plugin.
Warning: does not interact well with firebug's split screens.

Browser plugins most popular point of attack

We could have expected it. According to a recent ISS (IBM now) X-Force study, all these nifty browser plugins, have become the biggest point of attack for hackers.
The major source of vulnerabilities is the browser:

And the most important source of vulnerabilities within the browser are plugins:

Surprisingly only exploits for internet exploder active-X plugins have been reported, while I thought the firefox plugins were the most popular.
Maybe their vulnerabilities don't get reported because most are small projects run by individual freeware contributors? There is a list with officially recommended add-ons, but these recommendations are probably more related to stability than to security.
Maybe they don't count extension exploits?

Favourite Firefox extensions

Nicest thing about firefox these days are its extensions.
Internet explorer is also jumping on the bandwagon but somehow this seems to pollute the field with all kinds of nagware.
Anyway, here are some of my favourites

• Adblock

Filter out ads to make you pages lighter and more zen. And you can subscribe to filter sets, filtering out the common ones (I got one for belgian/dutch sites).

• IE tab

Lets you render firefox tabs using internet explorer (on windows), so you can browse pages that don't follow standards (e.g. Sharepoint)

• printpdf

Convert a web page to a pdf. Usefull if you want to send a html report page or such to someone.

• search buttons
• SearchWP: Convert search words in the search box into buttons that let you immediatly search in the web page you found. Great, with a drawback: you have to take care to click next to the buttons when you want to modify the searchbox.
• Searchbox Sync: Update your search box (left top) with search terms entered on search engine pages like google etc. By the same author as SearchWP and a great match.

• mousegestures.

No need to move to the menu's or keyboard anymore,
use the mouse to command your browser.


This one takes you forward in your browsing history. Press right mouse button, move left. As you see it highlights the command you draw.




This one does the same, but only by clicking. Keep left button pressed and press right. Obviously right button, then left takes you back



There's a standard set of actions and you can import your preferred actions from sets made by enthousiasts (plugins of the plugin), or add your own. I added this one from the gesture exchange site:



This mod opens my current page in a new tab. Handy when you want to "branch off" while browsing and still keep the main flow available.
