View Source Crashes FIrefox

Just purchased a brand new computer, Windows 8, latest version of Firefox, crashes everytime I try to "View Source". Has done this since I got the computer. Anyone know of any fixes? I use view source all day everyday.

Hello,
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
More information about reinstalling Firefox can be found [[Troubleshoot and diagnose Firefox problems#w_5-reinstall-firefox|here]].
<b>WARNING:</b>Do not use a third party uninstaller as part of this process. Doing so could permanently delete your [[Profiles|Firefox profile]] data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. <u>These cannot be easily recovered unless they have been backed up to an external device!</u> See [[Back up and restore information in Firefox profiles]]. 
Please report back to say if this helped you!
Thank you.

How do I "view source" in firefox 6

Since upgrading to Firefox 6 the option to "view source" is apparently no longer available (I used in in Firefox 5 only yesterday and am missing it already). Can it be made available please?

You can also go to Tools Menu -> Web Developer -> click View Page Source
Check and tell if its working.

How can I edit an html file in Firefox using View Source?

I have created an html webpage and saved it to my pc. I can't edit the html file in firefox when I right click on the page and select "View Source". I can view the code but I can't edit it. I can do this in IE9.
I thought I was able to do this before in Firefox.
Did my settings change somewhere that I can no longer do this?
Do I have to have something checked in the Web Developer extensions for it to work?
I'm using Firefox 24.0
Thank you for any help with this. :)

The View Source window in Firefox cannot be used to change computer codes. Nor can the Web Developer tools.
Sorry for any inconvenience.
I suggest using Programmer's Notepad.

How can I view the Firefox "chrome" source in Firefox 4?

I set up a userChrome.css file for myself about two years ago and I'm happy to say that '''most''' of it works fine in Firefox 4.
I do need to tweak one item, but I can no longer see how to view the Firefox UI "source" in order to make the change.
What command, tool or add-on do I need to use to view the Firefox 4 user interface "chrome" ? (i.e. HTML and CSS).
I've already spent about 30 minutes searching to no avail; probably using the wrong keywords.

You can open any chrome file in Firefox via the location bar, provided you know the path.<br />
XML (XUL) files need a view-source: prefix.
chrome://browser/skin/browser.css
chrome://browser/content/browser.css
resource:///defaults/pref/firefox.js
resource:///greprefs.js

I'm having problems opening various windows in Firefox. Eg. Downloads, View Source, History etc.

For quite some time I have been having some issues with Firefox 5.0.1.
I have been through all of the troubleshooting I can find but cannot fix the problem.
Most of the features that require a window to be opened in Firefox do not work. Eg. Downloads, View Source, History. I cannot see the windows.

I tried the localstore.rdf replacement from another machine running the same version of Firefox. Still didn't fix the issue.
I noticed on the machine that I was having the issue with there was a file present called localstore-safe.rdf, this file was not present on the machine where Firefox was functioning normally. I removed localstore-safe.rdf (made a copy of the profiles folder first) and it works.

I recently upgraded to FireFox 8.0. Now I can no longer see the option to view source code. Where has this gone?

Nothing more to add, cannot find view source.

"Ctrl+U" or in the View Menu

Just updated Firefox -- But where is the "view source"?

I use the "view source" feature all the time, but now it's gone! Is it gone for good? Can I find it somewhere else on Firefox?

Tools > Web Developer > Page Source (Command+U)

Every time I try to view images with firefox it crashes, shuts down and then asks if I want to re-open, how do I view images again with firefox?

Everytime I try to view images with firefox it crashes, submits a report, to which I've had no response yet, asks if I want to restart firefox with last session or start a new session. What is going on?

It only happens if I try to use google images with firefox. I've now narrowed it down to an extension, AVG SafeSearch, doesn't happen if I disable this.

When I have more than one tab open, if I click on a picture to view, when the window opens to view the photo, firefox crashes. I also notice while looking at a web page, the pinned tabs to the left of the bar are constantly reloading for some reason.

When I have more than one tab open, if I click on a picture to view/enlarge, say eBay, and I click on the items photo to enlarge it, when the window opens to view the photo, Firefox crashes. I also notice while looking at a web page, the pinned tabs to the left of the bar are constantly reloading for some reason, The green circle starts going round and round for no reason even though the tab is not being viewed. Both problems seem to have started after the last software update.

I'm having exactly the same problem, view source isn't working on a second monitor. Is there a fix to the actual problem rather than just moving the window to the first monitor whenever I want to view source?

HTML code displays on one line in browser view source

Hi,
In Dreamweaver, my HTML code displays returns, spaces, etc. However, in the view source option in a browser (Firefox in particular), all the code is displayed on one single line. I only found about this because I was having problems with my Google Ads not displaying. (A Google customer service person helped me to find a workaround for this since I still haven't figured how to get my code to display correctly.) So I have gone to Preferences in DW and changed my Code Format Line Break type. The result is the same with each of the three options: the code is all on one line when you check it under view source in a browser. (The server is Linux.)
Does anyone know how to fix this? Also, I think I know how this happened in the first place. I copied my code to TextEdit for a quick backup the other day, and then I pasted it back to DW. Bad idea? Is the only way to get the code back to normal to re-write it in a new HTML file in DW?

Pssh. Problem solved, but I'm not quite sure how. I did go back and try to clean up some redundant CSS and other things, but the HTML/CSS validator still shows that I have this one invalid <header> tag (www.nextmontenegro.com), but since that was written as part of the DW template, I just left it. Weird. Anyway, the code flows down the page now.
Thanks for the quick replies and helpful hints:-)

What happened to my View Source menu item?

I'm pretty sure that I used to be able to view the coded contents of web pages in the past. I just tried to do this with a web page and my "View Source" selection item under the "View" menu is gone.
Am I mistaken that Firefox used to have this feature? I have used Firefox, exclusively, for about the last 3 to 4 years, now; haven't used IE in quite a while.
Maybe with my latest FF upgrade, that feature was deleted in the upgrade.

Thanks. Glad to find more than ONE solution (I code "no right click" on most of the web pages I do). Tools / Web developer / Page Source works for me!

"View Source" problem in IE and Mozilla

I'm parsing a HTML data source using JAVA.
I do "View Source" of the page in both IE and Mozilla.
#1 below is from IE and #2 is from Mozilla.
1. <p><div class = "sub1"> <a name="..."></a>...</div></p>2. <p><div class =" sub1"> <a name="..."></a>...</div></p>Notice the spaces in the <div> tag. The spaces in IE and Mozilla are different. Could somebody please advise about this?
Thanks in advance for the help.

The two browsers use different programs to display the text of the source. IE usually takes the windows default and uses Notepad, whereas Firefox uses its own program. They are going to format it differently.
My approach would be to use the Notepad version and have notepad save it to disk. Only your own program can tell for sure what is really in the file, without notepad introducing display artifacts (like extra newline to do word wraps).

How can I view source on an app (preferably before installing)?

An app for Firefox OS is programmed in HTML and JavaScript. So, just like a webpage, I should be able to View Source, right? That's always been the empowering Mozilla approach, as far as I understand. View Source is great for learning by example (just like how I originally learnt HTML!), but also for open audit. Ideally I'd like the opportunity to look over the code before I agree to install.
If I go to https://marketplace.firefox.com/app/astroalpaca using my desktop browser, or if I find it in Marketplace using my ZTE Open, I can't see a View Source option anywhere. Where is it please?
I can understand not showing it on a small phone screen, but there's no reason why someone visiting Marketplace with a laptop/desktop web browser shouldn't download and inspect the app package.
If it doesn't exist (I'm starting to suspect this is the case), then where's my empowerment? What makes these fxos apps any less of an impenetrable consumer black box than android apps?

Wow OK. So for future reference, "View Source" (Ctrl+u) doesn't do it, since I guess the button comes from JS. So instead you need to:
* Open the inspector (Ctrl+shift+c)
* Click on the install button (to inspect it, not to install it).
* In the panel you get to see the source code for the button which includes the URL to the .webapp file (it might be hosted separately as in the example, or on the marketplace)
* You can copy and paste that URL and then open that file to see where the app content is delivered from, and then if you follow those paths you can view the HTML, JS etc.
So that's really quite buried, but I'm glad that at least it's technically possible! Not quite as easy as Ctrl-U ;)

Cannot View Source Without Issuing New Page Request, making FF Totally Useless for WebApp Development.

The question says all there is to be said about it.
This appears to be caused by an over-reaching security policy that has caused nothing but turmoil amongst my development team.
The bug exists somewhere in Mozilla's strategy; You are impeding our ability to reliably test and debug a secure web-app we've been building over the last year. It was frustrating enough fighting with the about:config settings anytime a new version of FF released (every other day recently), but now the issue is compounded.
Pump the brakes guys, you're going the wrong way. We're ditching Firefox-driven testing until you make this right.
Eric

Is this a new issue in Firefox 26?
When I watch for requests using Fiddler, I'm not seeing a second request when I view source for a few example pages, and the response time implies that I'm seeing a cached page. This may well vary based on cache headers or other factors.
One possible workaround until we figure out what's going on with your application might be to view the source of the rendered DOM. Ctrl+a to select the entire page, right-click, View Selection Source.
