Open RSS file in chrome then it ask for download - ruby-on-rails

I am working on Rails application where i created RSS feeds.
When i open link into Firefox it open good but in chrome it ask for download file or nothing.
What actually issue here or give me proper way to create and display RSS link if any buddy have a experience in it.
Thanks

This might be because, Your Google chrome does not have built in rss reader, to make google chrome lighter.
More information here.
To get rid of this problem you can add rss reader in google chrome by adding it from chrome webstore.
Follow below steps :
In your Chrome browser open
https://chrome.google.com/webstore/search/rss?hl=en-US
Enter 'RSS Feed Reader' in the search box (top left)
Press your 'Enter' key
In the results click the '+ Add to Chrome' button next to 'RSS Feed Reader'

Reading console.log of a page using chrome extension

I m not getting any idea in which direction I should search/investigate. I need to create a chrome extension which has a button. Clicking the button will show the console output of the devinspector window without opening the inspector.
I have seen some extension, which takes the screenshot and also log the console messages.
Which chrome API can provide this info?

Can't download reviewed Firefox add-on

Received the message below from Mozilla AddOn editors with regards to our new version of our add on:
"Your add-on, iGive Button 5.0.0.9, has been reviewed and is now signed and ready for you to download at https://addons.mozilla.org/en-US/developers/addon/igive-button-1/versions."
When I go to that link, I'm supposed to be able to download the reviewed and now signed add on. To try to do that, I clicked on the link which lets me manage the add on. At the top of the Manade Add On screen there is a link to the file (igive_button-5.0.0.9-fx.xpi): https://addons.mozilla.org/firefox/downloads/file/352648/igive_button-5.0.0.9-fx.xpi?src=devhub
However, when I click that link I get a "404 Not Found" error.
How do I get the signed add-on so we can distribute it from our web site?
Try for the sources in
about:config
and search for browser.dictionaries.download.url
verify the sources of the apps is correct
Did Mozilla send you a link to your preliminarily approved addon? When you click that link it takes you to developer hub. Under current versions there should be a link to your reviewed addon. Click that link to go to the management page for your addon. Near the top of this page you should see an element called "files" with your extension file shown as a link. You should be able to click that link to download your file.

Chrome refuses to load some PDFs in the browser

Our web application lets users upload forms in pdf format (which are then stored in a Windows Azure Blob) and also lets them view them afterwards. What we want to is embed the pdf in a lightbox sort of thing. This is working totally fine in firefox once something like Acrobat Reader is installed but Chrome does absolutely nothing with it.
Even before getting to the embed part, just opening it in a tab doesn't work in Chrome. Entering the url in firefox works fine and it will ask if you want to save or open in Acrobat Reader. Opening a new tab in chrome and trying go to the url does absolutely nothing. The page just stays a blank white, and the name of the tab remains as 'New Tab'.
I checked what was going on in the Network tab of the browser console, and all I see is a supposedly successful GET call (code 200) but the status of it is cancelled.

How to add a link to start a file download in a Rails Facebook canvas app

In our Rails app that runs in Facebook canvas, we have a workflow where a logged in user can build a document and then download it.
When the file is ready we show a link to it. This is just a Rails action that renders using send_file in dev or head (with proper NGINX config) in production. This part works fine.
In order to have the file start downloading without opening a new browser tab, we had the link target an empty iframe.
This was working, but a while back, presumably due to a security change by Facebook, our link stopped working. The JavaScript errors show:
Refused to display document because display forbidden by X-Frame-Options.
Users can still open the link in a new tab and it will download the file and a quick fix is to make the link open a new browser tab, but that isn't as good of a user experience.
We tried changing the X-Frame-Options in the headers and/or using meta tags, but this is canvas (running in an iframe), so that just stopped those views from displaying.
I also tried this form solution, but it didn't do anything (I could have been doing it wrong).
Is there any way we can build a button or link that will start the file download without opening a new browser tab?
Do you need to set the target at all? With no target set would it not trigger a file download popup in the browser, but leave the current browser window/tab on the same content?
