My question is along the same lines as this: Change the Chrome extension icon
But I'm wondering instead about the large icon of the extension on a new tab page. Can it change itself based on data? All I have in mind is a simple countdown-calendar (as in, the whole point of the extension is to be a big ol' number on your new tab page), so the actual code wouldn't have to be very long, if icon-changing is possible. (It wouldn't even need to sync or connect to the Internet for any reason.)
My strong hunch is no, because I've never seen an extension do so, and I would expect that if it could, my Chrome's Gmail button would probably display the number of new messages or something. But I figured it didn't hurt to ask.
PS: I've never created a Chrome extension, I just had that idea for one just now. Anyone reading this can feel free to do it themselves, but otherwise I'll make it when I get the time, as a learning exercise.
Only apps (not extensions) can have an icon on the New Tab page (NTP).
This icon have to be declared via the icons property in the manifest file, and cannot dynamically be updated.
I can imagine two ways to get a dynamic icon on the options page:
Create an extension that replaces the New Tab page. Have a look at the docs for Override Pages.
Create an extension that uses the chrome.management API to enable/disable apps. This method might work for your personal setup, but it requires a new App for each icon. This feels a bit hacky, but hey, it might work.

Writing guides in Google Docs and sharing them with other people as read-only is great. However, even when formatting it without the "Print Layout" option (the first toggle option under View menu), every viewer opening the document will see it in Print Layout, i.e. with half-empty pages before each page break. This is very annoying.
Is there any way to default the Print Layout to be switched OFF when a read-only viewer opens a Google Doc? Here are 2 ways for which I'm hoping:
via a URL parameter, so that the link I share determines the document will open with a switched-off Print Layout;
in Google Apps Script, with something like function onOpen(){ DocumentApp.getActiveDocument().setPrintLayout(false); }
(except setPrintLayout() does not seem to exist right now).
I'm mostly interested in the web browser version, and in the mobile app too (though less).
There's a similar question over there (with screenshots).
And there's a discussion dating back when switching off Print Layout in read-only Google Docs was not yet possible (it is, now, though only manually).
My Chrome extension doesn't need an icon - it's a one-liner extension that doesn't want to take up space on your extension bar.
How can I hide the icon by default?
Due to a change spearheaded by Google, all extensions now must have an icon in the toolbar area or the "overflow" in the menu.
Even if you don't have a browser_action, your extension will display an icon (or failing that, a tile with extension name's first letter). If you do not declare a browser_action, it will be greyed out and non-interactive, but will still be there.
The idea of this change is to provide visibility of otherwise potentially stealthy extensions ("Hey user, did you even know you have those installed?"). It's, let's put it, debatable whether it's the best approach, but that was Google's decision.
To suppress this behavior, add "converted_from_user_script": true to the extension's manifest.json. This works as of Chrome 61.
It used to be that visiting a link to a user script (ending in .user.js) caused Chrome to package up the user script as a content script extension with a generated manifest which included the converted_from_user_script key. Of course, this no longer works because all extensions (except in developer mode) now have to come from the Chrome Web Store.
Google thought it best to make the icon mandatory and I think so too, for reasons already pointed out by Xan.
Now of course you 're right, when you say that many extensions have no need for an icon, but the requirement of one still gives your extension an identity and Google still gives the user the opportunity to remove it from the toolbar. He simply has to right click the extension's icon and then choose Hide in Chrome menu.
I know, many users don't really bother to read all of the options under right click, or even right click it at all. But most of them still will make a single left click, to see if there is any option in the fancy new extension they added. You can take advantage of this by making a simple window where you point out their option of hiding the icon.
If you don't want an icon, you can omit the browser_action parameter from your manifest.json (the default_icon option is where you usually specify the icon). The browser_action section is what controls what you see in the toolbar.
I generally use firebug to remove unwanted divs and tags and resize stuff on the web-page .. frequently for gaming sites like chessbomb. But this is tedious, and every time tab reloads, i would have to do it all over again.
So is there any plugin which would remember the setting for particular site and apply it on the load itself. For starters i just need something to remove div tags based on names. If it can resize too then thats all the more useful.
Thanks.
You can use Adblock Plus with some CSS selector usage to do this. Look at the doc related to this here.
For example, you could probably use something like
domain.com##div.class
to hide those divs.
This is a use case for the greasemonkey firefox plugin. You'll need to know a little javascript, but if you're doing these sorts of things in Firebug, I would assume you won't find greasemonkey too dofficult.
Have a look at http://www.greasespot.net/ and http://userscripts.org/ and you may even find someone has already written the script you're after.
To quote wikipedia on Greasemonkey:
Greasemonkey is a Mozilla Firefox extension that allows users to install scripts that make on-the-fly changes to HTML web page content on the DOMContentLoaded event, which happens immediately after it is loaded in the browser (also known as augmented browsing).
As Greasemonkey scripts are persistent, the changes made to the web pages are executed every time the page is opened, making them effectively permanent for the user running the script.
I'm using a standard link list web part. What I want to achieve is before my users click on the link a pop-up javascript warning box will display, stating that they are leaving the domain. In regular anchor tag I would preceed the URL with javascript:ShowWarning('http://www.youtube.com');.
I've search the AllLinks table in the database but did not find the links was looking for.
Where or how are these stored?
Thanks,

Firstly, editing the SharePoint database directly is a really bad idea. You shouldn't do it unless you really, really know what you are doing, and even then you will probably break the system.
Secondly, any change made in the data will be what shows up in the editor, and I don't think the editor supports links that don't start with "http://".
A better approach is to use jquery to add the popup behaviour to the links when the page is loaded.
I've observed that under certain circumstances, a web browser will navigate to a blank page and then prompt the user to download a file. In my current situation, it's navigating to a URL that generates an Excel file. The download of the file works perfectly, but the user is now stranded on a blank page. There are two things I would like to figure out:
What causes the blank page to be displayed? It doesn't happen all the time. Is it the difference between using GET and POST (I can't recall seeing a hyperlink do it, but forms usually do)? Is it something to do with the Content-Disposition? In my current case, I've set the Content-Disposition to be "inline" because I want it to display in the browser in IE. Firefox (and presumably others) will of course prompt to download because they can't display it inline. It is the situation where the user chooses to save it that the blank screen results.
If it is possible, I'd like to display some content on this blank screen to provide the user with a message like "your file has been generated, click here to go back to the main screen" or somesuch. Is there a way I can do that?
I'm using an IIS extension written in C++, so solutions for ASP, PHP, etc will not be helpful unless they're generally applicable (though I wouldn't mind learning about solutions in those languages!). Thanks.
I think you practically answered your own question: setting content-disposition to inline does exactly that. One solution that comes to mind is browser detection: use inline disposition if the browser is IE, attachment otherwise.
BTW, as a user, I prefer sites which offer me a choice whether I want to download the file or view it inside the browser (when, for example, accessing a PDF file). In this case, I would consider having a link/button for downloading the file, and adding a second link/button for IE browsers to view it.
