1. Go to your Google+ business page and make sure you are using Google+ as the page, not your personal account. The page name should be displayed at the top right.
2. Click on the options icon (the cog) at the top right-hand side of the screen, then select ‘Google+ settings’
3. On the following page you should see an option called ‘Managers’ on the left-hand side. If you don’t see it, double check that you’re signed in as the page and not your personal account.
4. Select the Managers option and on the following page you are able to add another manager to the page via entering their email address. Make sure you enter the email address that is associated with the user’s G+ account.
5. The user is then sent an invite which they must accept before they can manage the page. Until that time the invite is marked as ‘pending’.
6. Once the user has accepted the invite you have the option to remove them from the same page. There’s also the option to transfer ownership if you’re no longer involved with the project or business the page is promoting.

Adding Google+ page Managers

When linking to an external JS, css or image file that is available over both https:// and https://, you can use a URL of the form:

//domain.com/path/to/asset

for example (loading the jQuery library from Google’s CDN):

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js"></script>

Your browser will request the asset using whichever protocol you’re viewing the current page in.

This has implications if your viewing a page locally via file://, which is why you’re always better off using a local web server rather than opening a file directly. There’s also an issue that causes IE7 and IE8 to download the file twice when this method is used in <link> tags or @imports statement within CSS, so I would say it’s best of avoided there. More details here.

This technique allows you to quickly and easily avoid the dreaded ‘this page contains both secure and nonsecure items’ warning in Internet Explorer.

1) Download language pack from here. This mozilla.org page has language packs for most languages. After installing a language pack you will need to restart your browser

2) Change locale string. Navigate to about:config in your address bar. After accepting the ‘here be dragons’ warning set the filter to ‘general.useragent.locale‘, right mouse click on the value and choose modify. Change the language string to the preferred value, for example ‘en-GB’ for British English or ‘fr-FR’ for French.

After a browser restart your Firefox should be in the preferred language.

Now it seems the malicious code only targets IE6, and Microsoft released a patch for it yesterday (the 21st). Hopefully these security alerts will have caused some people to jump ship from Internet Explorer to one of the alternatives, and we can see those usage stats, particularly of IE6, start to drop off.

Source: StatCounter Global Stats – Browser Market Share

If you spend time building web pages, working with CSS, Ajax, javascript etc this plugin can be amazingly helpful. It allows you to inspect DOM elements on the page, see what css styles they have applied to them, where these CSS styles are defined and even preview changes without having to modify the source.

HttpFox

HttpFox allows monitoring of http traffic between your browser and the web server. Also allows you to inspect headers, POST data, cookies etc. Incredibly useful when working with Flash applications when you want to see what data is being loaded in, and also for easily checking for missing or broken page components.

YSlow

Another tool for website optimisation. Developed by Yahoo, YSlow analyses various components of a web page and gives you tips on areas that can be improved based on Yahoo’s rules for high performance web sites. It also includes neat tools to do things like image optimisation. YSlow runs on top of Firebug and so you’ll need to have that installed before you’re able to use it. Yahoo’s Best Practises for Speeding Up your Website are a real goldmine of information and well worth looking into if you’re involved with making sure your getting the best possible performance from your website.

HTML Validator

The benefits of having correct, cleanup HTML/XHTML markup are obvious. This extension parses and validates your markup using two tools from the W3C – Tidy and OpenSP. You are then presented with a list of issues, making fixing poor markup a quick and easy process. It also has a useful feature that allows you to view html source after javascript execution, which is useful when working with Ajax.

Web Developer

The web develper extension brings together stacks of different tools that are useful for web development, tools for inspecting web pages, validating, disabling components, resizing the browser window, etc etc.

Flash Tracer

Very useful if you work with Flash, this extension allows viewing of trace statements from a Flash movie when it is embedded in a web page. Requires you to use a debug Flash Player.

Flash Switcher

I use this in conjunction with Flash Tracer. As the debug flash players can be slow compared to the normal player, you ideally don’t want to be running it all the time. Flash Switcher gives you a quick and easy way to switch between different flash versions. It also allows you to test your flash under different flash player versions.

FireShot

This extension doesn’t feel quite as slick as other extensions but provides some neat functionality. It gives you a quick and easy way to take a screengrab of the current page (either visible area or the entire page), and then carry out simple edits and make annotations to the grab before saving it off or sending it via email. Very useful when you want to send someone a screengrab highlighting an issue or area of interest.

ShowIP

A simple extension that tells you the IP address of the site you are visiting. If you maintain several servers this can be useful to tell you where a page is hosted

Clear Cache Button

Allows clearing of your web cache without having to delve through submenus. if you find yourself doing this a lot, this extension is worth getting.
