Is there a way to simulate not having flash player installed, so I can see what users who visit a page without the plugin see my page?
Thanks!
I recommend downloading MS Virtual PC or VMWare Server (both free) and create a VM to test this functionality. Its the only way to be sure. Also gets you the flexibility to test a lot of browser versions.
In Firefox , Tools -> Add-ons -> Plugins -> Shockwave flash -> Disable
Doesn't require you to restart the application. The name of the plugin can vary. It's how it's called in my Linux box.
IE - Disable the flash player plugin (Tools, Manage Add-ons)
Firefox - install the NoScript plugin
Chrome - install the FlashBlock extension
Other browsers, there's usually a way to temporarily disable any plugins you don't want.
In chrome, inside the URL bar, write: chrome://settings.
In the new page, click on disable under the Flash plugin
Get Virtual PC and download the IE Test environments.

Our web browser plugin has worked in all IE versions and still works fine in IE9 and IE10 but in IE11 the plugin is not even recognized and listed as an add-on. It's as if IE11 no longer supports ActiveX.
NOTE: this questions is asked as the developer of the plugin and not the end-user who might need to correct IE settings. So suggestions for how to detect ActiveX or how to adjust a browser settings to allow ActiveX are useless here.
We assume that what we need to do is make adjustments to the ActiveX structure so that IE11 on Windows 8 approves the plugin so that it can be available to the user at their discretion, ie: list it in the Add-on Manager.
A sample project and test page can be downloaded from here - http://addmine.com/temp/EPM_project.zip
Surely there is a workaround but what do we need to change?
As of IE11, add-ons are supported only for IE on the desktop. If you're running the Windows Store experience of IE, then your statement about IE11 not recognizing the plug-in is absolutely correct. This article shows how you can have this experience prompt the user to open the page in the desktop experience of IE, which will support your plugin.
Having said that, it's entirely possible that you do change your plugin to support changes to the Windows 8 security model. Here are a couple of links to get you started:

I need to see the output by mobile joomla plugin in my regular browser, to be able to style and tweak things easily.
In older versions of mobile joomla ther was an option ('Mobile Always') that would output mobile views all the time. But I can't find it current version (1.0.3)
You can always install User Agent Switcher for Firefox. It gives you the ability to change to a mobile user agent and also a few others things such as IE6 and IE7. You can also add others. Hope this helps. Regards.
I'm looking into chrome frame and I'm wondering how it works.... http://scriptsrc.net shows that it's a javascript that can be embedded on the page....
http://code.google.com/chrome/chromeframe/ shows it as an install file... does the JS prompt for an installation or something?
Google chrome frame is a plugin (think Adobe Flash) for Internet Explorer, that replaces core modules of IE (unlike Flash), like layout/rendering and javascript. But the UI remains. Then there is some javascript that can detect if this is real IE or IE+Chrome, and also offer an install option to the user. Also there is a HTTP-header and a meta-tag that are required to switch IE to chrome mode, when available.
The JavaScript is to detect it and enable it if it's there. (scriptsrc is just giving you the link to the file, which is on the Google CDN.) The end user does have to do a one-time install of it, it's a plug-in (like Flash or Java). Quoting from this page in the Google documentation:
In Internet Explorer, check() determines if Chrome Frame is installed. If not, the user is prompted to install it.
I have an HTML5 application that requires offline support. For running the application, I use a local Apache server. I am trying to figure out what the best way is to simulate offline mode.
Currently, in Firefox I disable my Air-Port to simulate offline mode, but this is a pain.
Any suggestions? I am open to using other browsers, if a method exists that doesn't require turning off my Internet.
For Firefox
☰ (hamburger menu)->More->Work Offline
Google Chrome doesn't appear to have this feature
Edit:
Also, another alternative is slightly more time-consuming to setup in the beginning but might be worth it. For Firefox/Chrome there should be proxy plugins, set up a fake/bad profile for each so that you proxy to something that doesn't exist... like 127.0.0.20:8080. After that you can switch the proxy setting on and off to emulate a full-stack test.
The other answers are out of date. The only place this appears in Firefox v92 is under
File > Work Offline
The File menu can be accessed in the top left of Firefox by pressing the ALT key.
Be warned that this does not prevent traffic from "localhost" loop-back itself, unless you additionally turn on
network.disable-localhost-when-offline
preference in about:config.
Bugzilla issue: Add option to disallow connections to localhost while in offline mode.
In Chrome you can open developer tools switch to the network tab and set throttling to offline
For Firefox, from the ☰ (hamburger menu), choose Web Developer > Work Offline.
For Chrome, open DevTools and select the Network panel. Throttling is set to Online (Disabled) by default. From the dropdown menu, you can choose presets Fast 3G and Slow 3G, but to simulate Offline Mode, you want to choose Offline.
I would like develop on add-on for Firefox , which combine with other available add-on's and make new add-on which providing new features + existing add on feature tooo.
The question is unclear, but here is some information from Mozilla.
How to develop a Firefox extension
and
Developing Mozilla addons
You will find the code of all installed extensions in the firefox profile folder. In my vista machine, it is located at C:\Users\<ur name>\appdata\Roaming\Mozilla\Firefox\Profiles\<randomstring>.default\extensions\
Unzip the jars and learn the code, edit as per your needs and restart firefox. Remember that when firefox automatically updates the extension, ur changes will be overriden. If something goes wrong, start firefox from cmd with -P switch to create a new profile or goto safe mode using firefox -safe-mode and uninstall and reinstall the extension from its website.
