Install custom plugin on Google Ghrome Ubuntu 14.04 - linux

I've got a problem while trying to install rutoken plugin for Google Chrome v. 40.0.2214.115 (64-bit) on Ubuntu 14.04.
That's what I try:
Download plugin from http://www.rutoken.ru/support/download/rutoken-plugin/ and unpack files, so I had librtpkcs11ecp.so, npCryptoPlugin.so files.
Create a directory for plugins, in the Google Chrome's installation directory.
sudo mkdir /opt/google/chrome/plugins
Copy *.so files to the plugins directory.
Then I've restarted Chrome:
google-chrome -–enable-plugins
The problem is that when I run chrome://plugins/ there is no such plugin in a list.


It seems Java JRE is not more working on Chrome

NPAPI support by Chrome
The Java plug-in for web browsers relies on the cross platform plugin architecture NPAPI, which has long been, and currently is, supported by all major web browsers. Google announced in September 2013 plans to remove NPAPI support from Chrome by "the end of 2014", thus effectively dropping support for Silverlight, Java, Facebook Video and other similar NPAPI based plugins. Recently, Google has revised their plans and now state that they plan to completely remove NPAPI by late 2015. As it is unclear if these dates will be further extended or not, we strongly recommend Java users consider alternatives to Chrome as soon as possible. Instead, we recommend Firefox, Internet Explorer and Safari as longer-term options.


I installed plugin updated but I face issue at testing time plugin not work properly in Chrome using link http://java.com/en/download/installed8.jsp?detect=jre If you got message "This plug-in is not supported" then follow following steps:
In your URL bar, enter:
chrome://flags/#enable-npapi
Click the Enable link for the Enable NPAPI configuration option.
Click the Relaunch button that now appears at the bottom of the
configuration page.
and test it again using http://java.com/en/download/installed8.jsp?detect=jre link.

UFT ObjectSpy unable to identify objects in chrome

I was trying to make ObjectSpy work with Chrome browser but its unable to identify objects.
Whenever trying to identify getting this: WinObject("Chrome Legacy Window").
I tried reinstalling UFT and chrome and Microfocus extension for chrome but it didn't help.
I have downloaded extension from internet and its shows the version as Micro Focus UFT Agent
2022.0.1.25. My UFT version is 14.53. I am not sure if its compatibility issue.
Please help.

UFT 14.53 is pretty old as far as supported browsers are concerned (July 2019), if possible I would suggest upgrading to the latest version (upgrades are included in the license).
Failing that you can try to remove the extension from Chrome and install the one that comes with your version of UFT (in <UFT installation dir>/Installations) although I'm not sure it will work with current versions of Chrome.

Various versions of chrome on linux

I'm looking for the way to conduct cross-browser compatibility test on my ubuntu. Firefox and opera don't cause problems, but I didn't find any guide how to install older versions of chrome. Do you know how to check my code in this browser on my computer?

You can take screenshots in different versions in Browserstack. Also you can browse there using different browsers, but you will need to pay for that.

In general, there is no need to test compatibility against anything but the latest version of Chrome, since Chrome updates itself automatically. Just expect that anyone using Chrome to view your site will have the latest version.

to enable chrome.commands in the current chrome stable release

I am working on a chrome extension that plans to use Chrome's upcoming API chrome.commands for defining global keyboard shortcuts.
This API will possibly be released in Chrome 25 (says here) and it is currently available in Canary, Dev and Beta. (have tested on Canary but not tried on Dev or Beta yet).
My question is: is there a way to enable this API in the current stable version of Chrome? I have tried enabling "Experimental Extension APIs" but that is not helping.

If you look at Source Code of Say 23.0.1248.0 here, you do not find references for these code!, So they are undefined in any older revisions.

Where can I download JRE 7u5 plugin for any browser?

I was looking for a good exploit to use as my final project for security class so I though for JRE 7u5 bug to exploit using Metasploit.
Where I can download that version of plugin for FireFox/IE/Chrome, for whatever browser?
I Googled for hours now and I can't find a link =?

While the older downloads are not listed any more, I think you'll find that they follow a well-defined naming pattern. For example, look at the download links on this page and modify as needed:
http://www.oracle.com/technetwork/java/javase/downloads/jre7u9-downloads-1859586.html
Not sure about Chrome, but I believe installing JRE on Windows adds it as browser plug-in for IE and Firefox. If not, follow these instructions.

Cross-Browser Extensions API?

There are tools for developing cross-platform browser plugins.
Are there any similar tools or APIs for browser extensions (i.e. toolbars, or filter systems like AdBlock)?

Yes, but unfortunately each one has significant drawbacks.
Kynetx supports IE, Firefox, Safari, and Chrome, but extensions are dependent on the Kynetx extension to work. In addition, Kynetx apps are built using an odd, proprietary Kynetx Rules Language. There is no cost to use the Kynetx platform. UPDATE: Kynetx has shut down
WebMynd supports IE, Firefox, Safari, Chrome, and is in private beta. From what I have been able to determine, WebMynd is a very small San Francisco-based startup that is still getting off the ground. Their library is standalone and provides a Javascript API, and they use a monthly billing model. UPDATE: company pivoted, now for mobile, trigger.io
Crossrider supports IE, Firefox, Chrome and Safari. Recently out of beta (as of June 2012), Crossrider is free and offers a jQuery-based development experience. Publishing methods for your extensions include an embeddable website widget, download links, and a customized windows installer. However, CrossRider does not allow you to self-host your plugin files. UPDATE: As of 27.09.2016, CrossRider is terminated and it will be available only until 27.10.2016.
KangoExtensions supports IE, Firefox, Chrome, Safari, Opera. Seems very new and bleeding edge, like Crossrider, also looks promising. UPDATE: No updates in over two years.
IE and Firefox seem to be the hardest to develop for, although Mozilla JetPack aims to greatly simplify Firefox extension development.

There is also very young framework for cross-browser development called BabelExt, from the author of Reddit Enhancement Suite. I like that it builds restartless Jetpacks for Firefox.
See more on github, https://github.com/honestbleeps/BabelExt

Mozilla has recently introduced WebExtensions API. For now it's actually almost a copy of Chrome Extension API (but some APIs aren't implemented yet). It has been introduced just a few days ago so it still has a lot of problems and unsupported APIs. But if you're interested in writing extensions for Chrome, Opera and Firefox you should pay attention to the state of WebExtensions API.
UPD 27.10.16. There is a page Are-we-WebExtensions-Yet which summarises the current state of WebExtensions. By their current estimate 44.99% extensions from Chrome store should work in Firefox.

ExtensionMaker is another one project related to cross browser extensions development. It is not a real framework. It is kinda IDE that allows you to design basic extensions.
Of course, it is not suitable for a serious projects. But I like the idea.
Full featured version is available for free. There is just small limitations on the way of using generated extensions.

Yes, the browser extensions development company has a framework-one code for all browser views
