I've started using Firefox developer edition, after many years of using Firefox with firebug.
A slightly annoying artifact that I cant seem to get rid of are the rule lines - when I select an element (e.g. a button) Firefox developer edition adds rulers to the page (dashed blue lines) and highlights the elements in yellow.
The issue I'm having is that these rules (sometimes) appear fixed on the page - they don't move with the selected elements and I cant make these rules and highlights disappear (alternatively, I can't make them stick by myself), I've tried every setting in the console, I've tried refreshing the page, all to no avail, the only way I can seem to get rid of them is to navigate to another page and back to my original page.
Does anyone know a setting, or a keyboard shortcut to make these lines go away? is it a bug in Firefox?
To answer my own question:
It seems the only way to get rid of the rulers without navigating to another page is to close the inspector, and re-open again (a quick double-press of F12 does it) - others don't have the same issue with the same version of Firefox developer edition, Though I cant find a bug-report about this

I need to debug some JavaScript an' I use Chrome dev tools. I'm a newby in JavaScript (just started to learn a couple of days ago), an' at work I could set breakpoints via the Resources pane. But at home for some reason I can't do this: after the click no breakpoint appeares.
I have Chrome version: 26.0.1410.64 m.
What could be the case?
clicking on the De-Obfuscate Source button (i.e. {}) solved this issue for me.
I'm a fool! haha! breakpoints are set in the Source pane )))
It's been a while, but in version 33.0.1750.146, but my problem was that I was on the Sources pane (I'd call this a tab; it's one of the items at the very top of the window), but I was on the Content scripts tab (on the left hand side). I needed to switch to the Sources tab.
To be clear, there are two sets of Sources tabs; one is within the other.
UPDATE 2016-01-07: Now I'm on 47.0.2526.106. The only thing that worked for me today was to close DevTools and re-open. It was a little finicky. It worked once, then stopped, and I had to close the DevTools and re-open again. I saw #johntrepreneur's answer about closing the browser, but unfortunately I have too many tabs open on too many workspaces, so that's too much of a pain, so I didn't try that, although I have to assume that would work.
Other solutions didn't work for me. Had to close and restart browser to be able to set breakpoints again.
This also happens when there is a JS error in your code.
Some sort of weird built in function in windows 10 i think because I did press a few buttons by accident. Some of my keys even stopped working in certain areas of visual studio. F.e the letter "c" stopped working in the find window.
Mine did this and no solution worked, i pressed alt, windows key and function key a few times and my problem went away.
Fixed as follows: For me, the issue stems from having set up Chrome to interact with operating system files. If you set this up, then the fact is evident from a green dot by the file name. At some point, I could not set a breakpoint in a recently edited file. I fixed this by disconnecting the interaction, as follows: When viewing "sources", above the code, there were some file names listed. Clicking the [x] to make the particular filename go away gave a caution message; I proceeded without saving. After that, I was able to set breakpoints for that file.
I also had this problem. However, once I closed the popup message in my browser, suddenly all my breakpoints that I set in that time appeared. Mental note: Don't set breakpoints while your app is showing a popup.
I couldn't find any direct fix for this problem.
It seems that chrome keeps settings of your site stored somewhere whatever you do to clean it. (I tried removing the folder from workspace, closing et reopening chrome etc... and nothing worked).
A workaround is to change your site's url to make chrome consider it a new site
If Firefox is already displaying a local HTML file on my PC in a tab (address = "file:///...") and I modify the file using my favorite external editor, sending the file to FF to display the edits results in FF opening a new tab with a fresh instance of the original file, rather than searching to see if the file is already open it it and reusing that tab.
Sure, after editing the file I could reopen Firefox, navigate along the tab bar to the existing tab for that file and click Refresh. But IMO FF should be capable of doing this for me. In my work, by the time I need to refresh FF, the tab currently open is not likely to be that of the file I am editing, so I continually need to return to the original page to refresh it.
My efforts to work around this include:
1)In about:config, *setting browser.link.open_newwindow* from 3 to 1.
2)Running Firefox and passing it either the filename or the URL to the filename (as -url parameter).
3)Looking for a suitable add-on.
I am not fond of either Firebug or Aurora and prefer my own editor (EditPlus), which with I am far more comfortable, to edit web pages. However, its inbuilt browser does not display properly on my screen, so I need to view results of edits in Firefox.
Can anyone suggest a solution to this problem? I've searched here without success. The best solution would be another about:config setting. Thanks in advance.
(added) After all, in EditPlus, if I send it a file (in document-centric mode) which it has already opened, it simply changes focus to the existing tab. Why can't FF do this?
Thanks for suggesting the "Restore Open_External" add-on.
I tried it but it doesn't help me here. What it does is:
(quote)
"browser.link.open_external (Integer). This option specifies how Firefox opens links launched externally, e.g. e-mail or Microsoft Word. 3 options are available;
1. Selecting this option launches the link in a new tab in the most recently active Firefox window. This would be recommended if you don’t wish launching such links to affect your most recently active webpage and you aren’t concerned about the links content.
2. Selecting this option launches a new Firefox window to view the link. This would perhaps be the safest option to select (In that if you launch something questionable you may be able to end the process without affecting other windows).
3. Selecting this option (default) launches the link in the most recently active Firefox window/tab. This would be recommended if you aren’t concerned about launching links is the most recently active window/tab (You can always use the back button to view the previous page if you need)."

I'm sure many find this useful. Option 1 would have been fine for my purposes if it didn't insist on opening a duplicate tab. This add-on does nothing to prevent duplicate tabs being opened. So I began hunting for some add-on that might PREVENT a new tab being created in response to an external app sending a file to Firefox. Tab Mix Plus is supposed to do this, but I got lost somewhere in the maze of options. Then there is Prevent Duplicate Tabs, which creates a whitelist of all pages where duplicates are not permitted. This is far from automatic and seems pretty lame to me, as is Duplicate Tab Closer which doesn't prevent a duplicate tab from being created; instead, you have to press Ctrl+Alt+D to remove existing duplicate tabs - equally lame. deduplicate-tabs is similar, but offers a button to remove duplicate tabs.
Maybe I'm missing the point, but I can't see why anyone would want duplicate tabs of the same page, one a later version than the other. In fact, FF ought to be able to automatically refresh a tab when one reselects this, without having to resort to the "refresh" button. But that's just my rant.
If anyone reading this can think of a better way to integrate FF with an external app that modifies a web page, I'll be most grateful.
Install that addon:
https://addons.mozilla.org/en-us/firefox/addon/restore-open_external/
Go to addon preferences and set:
'in the current tab of current window'
Next time you open a new url from an external program it opens in the same tab.
You can also install the
duplicate tabs closer firefox addon which, as the name suggests, allows you to automatically close duplicate tabs
You can configure it to:
Close the older tabs and keep the new tab
Select the new tab
Try this addon.

While it's simple to pin/block a link-screenshot in the new beautiful tab page in firefox I see no way to edit the list of blocked/pinned items, does anybody know how to do it?
E.G. I blocked a page but now I woukld like to unlock, how to do it?
Thanks.
This is for FF17 on Windows, Mac/Linux users cf below
To unlock a blocked page quit Firefox, download sqlitebrowser at sourceforge.net (~6MB as of now, Windows only), use it to open chromeappsstore.sqlite in your "Profiles" directory. On Win Vista that's eg:
[DRIVENAME]:\Users\[USERNAME]\AppData\Roaming\Mozilla\
Firefox\Profiles\[ALPHANUMERICSTRING].default\chromeappsstore.sqlite
Switch to the "browse data" tab, open the edit view of the value corresponding to the "pinned links" key (double click on it). Replace one entry (eg a null) with
{"url":"YOUR_URL","title":"YOUR_TITLE"}
apply changes, save changes.
There's a key "blocked links", too. Intuitively, deleting blocked urls from its value should help, but it didn't when I tried. The trick above is clumsy, but so far I couldn't google anything more elegant. I couldn't find anything useful searching Firefox' about:config tab, either. I found this solution when doing a string search for the blocked url in my profiles directory.
Mac/Linux users should find other sqlite browsers. When using the firefox addon SQLite Manager you would need to make a copy of the database file first and edit that. Afterwards quit Firefox and replace the old file with the new one.
Here's the bugzilla entry ("Bug 722234 - [New Tab Page] provide an option to undo remove a site "), status is assigned, not solved. On comment reads: "Currently, there is now way to undo removal of a site or resetting the page using the new layout."
There's an easier way to do it without downloading, especially for people who may not navigate computers very well. Mozilla does have a way to do it, they just label it poorly and it's a bit roundabout.
Make the page you blocked on your new tabs page a Favorite, then click and drag to an empty space on your new tab page and it will autopin. The one downside is that if you unpin it the site will disappear again. I was frustrated for weeks after I removed Google and there doesn't seem to be much help out there that's simple.
"Make the page you blocked on your new tabs page a Favorite"
What does that mean? Bookmark?
I clicked the PIN icon on a couple and instead of pinning it, it seemed to completely remove that page from the New Tab selections altogether...and indeed, I see no way to get it back. Why would pinning something take it away!? And they were pages I use many times every day; very disappointed.
And those that I clicked ARE in my bookmarks ('Favorites' is an IE term), but they have not reappeared as suggested above.
The sqlitebrowser approach above is too complex and I can see it going awry trying to get all that right. Sad day here for me.
I have a problem in XCode 4.2 when I have the autosuggest feature turned on. Whenever an autosuggest (autocomplete) pops up, the cursor will jump to the top of the file, to the second character of the first line. This happens regardless of whether or not I select the autosuggest or take any other action. As soon as I turn off the autosuggest feature, this behavior stops happening.
I have turned off all key binding associated with jumping to the top of the page and have deleted all derived data for the project as per some suggestions I have heard, but have not been able to solve the problem.
Anybody have a solution?
I had similar problem Xcode cursor jumped randomly. It was triggered by an editor theme using an italic font. I changed the font to a regular one, and the problem was resolved.
Simple solution (or workaround):
Open Preferences.
Open Fonts & Colors tab.
Select Basic theme.
I got the hint from this page.
Just in case there is a bounty awarded :) let me repeat my "solution" from above: I suggest moving aside your /Developer folder and re-installing Xcode. Simply running the installer w/o removing the old /Developer folder may not replace all the necessary files. Good luck.
I have had a similar problem where the cursor jumped to the top and I couldn't scroll down. I don't know if it is the same problem that you have but there is no real solution. Its just one of Xcode's bugs there are a lot more. Open another file in the project and go back to the file you were working on, close and reopen the project or restart Xcode. Thats the only solutions I found.
If thats not working, then you can always re-install Xcode
For a couple of days I had noticed that the "script" tab of firebug had not been working. I ignored it because I wasn't working with javascript at the time.
Then the day came I was going to need that script panel, which still wasn't working, so I decided to reinstall firebug.
And now, when it's installed, it's just plain gone. No icon that I can see, neither on the bottom bar nor the top bar. No mention of it in the tool menu. The only evidence it's installed is an entry in the extensions list and a file in the extensions folder.
I've tried googling but have not fond anything that sounds like my issue.
I'm using firefox 6 on Windows XP.
For some reason, Firebug changed it's toolbar button (and removed the old one) from the old bug to a blue default cursor over a width, short box. Right-click on a toolbar, select Customize, and look for the icon next to the bug at the large picture of Firebug at top of this page:

Try disabling any other extensions you have installed?
