While using Google Chrome Timeline feature I have noticed a strange thing. On my PC in a workplace flame chart is very flat, showing only 1-2 function calls deep. My first thought was: "Well, that is the way this thing works". But when I opened the same webapp from home and a flame chart was much taller, showing all function calls.
Both browsers are in the same version (51.0.2704.84 m - latest at the moment). All settings in DevTools are same.
Flame chart from computer at work:
Flame chart from computer at home:
My question is simple: why computer at work does not show full call graph and how can I fix this?
Is everything checked under the Event Log tab (below)? I see that painting and rendering events are not visible in your bottom screenshot.
Looks like a bug on your work computer. It shows no JS frames at all. If it's still reproducible please file it at https://crbug.com
I assume you were recording with JS Profile checkbox marked.

i'm struggling with the classic HTML input of type file. I was using it on my angular application and i had freeze sometimes, the whole browser became unresponsive, and the only thing that works is the scroll.
You can't click any buttons, select any text or even change tab on the browser for about 5 seconds. I tried a lot of different file type and sizes and it doesn't change any of this, it even freeze sometimes when i don't select any file in the explorer and i click the close button directly.
So I thought it was my implementation that was bad and i went to the Mozilla developper website where you have an example and I have exactly the same behaviour. I also tried to take only the HTML from the Mozilla website and put it alone on a .html file and again, same behaviour.
This does not occur 100% of the time, but I would argue that on my end it does it about 60/70 % of the times.
I tried it on chrome and Firefox (both up to date), on multiple computer (all running Windows though) and i have the same behaviour on all of them.
I don't have any error or anyting in the consoles.
I don't know what to do with this, i'm pretty sure it can't be the file's input on the whole web that are bugged, but i tried a lot of various things with always the same results. Should i report it somewhere? ( if so, where? ) Or what would you suggest to do to investigate this further?
I couldn't find anyone discussing this issue on the internet apart for this thread that had no solution, they also say in this thread that the bug is not reproducible in Edge, but i just tried and it does the same thing.
Thanks for reading me and for any help about this.
Chrome freezes for few seconds when after any use of file field.
It was because I had a shortcut in "Quick Access" menu in windows explorer. This shortcut has been linked with a folder shared by network. I've removed this shortcut and everything is good now.
Same here, I have a mapped network drive that is not responding, this make a 5 seconds delay. After unmapping the drive, no more delay. The delay is the same in firefox or chrome.
Same here, if you want to remove it, on Windows 10, click on the icon Quick access (blue star), then right click on the dead link appearing in the "Frequent folders" panel on the right panel and choose "Unpin/Remove from Quick access". There should be no error message.
So I'm trying to develop a webapplication and I'm trying to check it out on mobile.
I'm currently using Cordova and JQuery Mobile together with ripple.js to view my application in my browser.
The first issue (as far as I know) is that ripple.js will work best in Google Chrome, so this is my only test platform.
The second issue is that when I toggle Device Mode on, it doesn't show me the black dot (cursor) when I enter the rendered version.
I'll explain my situation or a scenario:
As an example I'll go to http://google.com
I press F12 to enter developer mode
I click the Toggle Device Mode button
I will see my cursor, until I enter the generated mobile canvas. While I would normally see a black transparant dot, I now see nothing.
I can however click and drag like I would normally do, but I can't see what I'm doing.
The things I already tried:
Reset all the flags back to default
Reset all developer tool settings to default
(edit) Installed a previous version of Chrome AND Chromium
So question is, how do I get my cursor back?
Extra: I'm using version 49.0.2623.87 m, but that's not related since my co-worker, has the same version and he sees the cursor.
(edit) currently I'm using the mouse option where I press Ctrl to see the circle which indicates where my cursor is, but this really has to be a temp solution.
(edit) I fixed it by doing a combination of things. So I'm not sure which exact thing fixed it. I removed a few programs that I installed after it still worked. I uninstalled about 4 of them. Also I did an update of my graphics card and then did a reboot. So it could be either the graphics card update, the software uninstall and/or the reboot.
I had the same issue. (note this question might be a duplicate of this one)
Following the advice on the Chrome forum here I changed the Quantization Range in my Intel HD Graphics Control Panel from "Default Range" to "Full Range". The touch pointer (grey circle) appeared immediately.
If that doesn't help you may have to change refresh rate too. Changing from 59p Hz to 60p Hz or some other refresh rate might help.
This should also help.
Open the mouse control panel.
Select the Pointer Options tab in the Mouse Properties window.
Then enable Display pointer trails option.
In case you don't like or are getting annoyed, like me, due to the trailer. Move the slider to the Short position and the trailer becomes near to non-existent or invisible.
I fixed it myself, yet I'm not exactly sure how I did it. I edited my original post and added the solution in the last paragraph.
Had the same on my Asus laptop with Chrome 66
Resolution that worked for me
Graphics Control Panel > Display > General Settings > Scaling > Change to Scale full screen.
OFF your Asus Eye Care Switcher.
I am posting this as answer because above mentioned answer didn't work for me but I had this issue when I had a monitor attached to my laptop, for development work. I played around with my display settings and discovered that IF the scale on my second monitor did not match the scale on my laptop, the mobile development mode cursor would disappear. (windows 10)
If this is an issue for anyone just go into Display settings -> Display -> Scale and Layout --> make sure that both your laptop/desktop matches the display scale of your second monitor.
Hope this will help.
When a site gets stuck in chrome with the 'loading www.site.com' status, Is there anyway to know which of the elements on the DOM is delaying the load? for example, it can be an external js file or image that is taking long time to load. I tried using the network tab in the DeveloperTools, but it only shows the elements already loaded and the time they took. I couldn't find a way to see which element is stuck.
I found a way that I'm not sure it works in all cases, but it did for me. I used the Timeline tab (now shown in the Performance tab), it's one of the tabs in Chrome Dev Tools.
Open Chrome Developer tools (F12 or CMD + Alt + I in Mac) and click the Performance tab
Make sure you drag the grey timeline bar all the way to the right, you want to see the most recent section of events so you can find what's getting stuck:
Check just down below the records sidebar. If you don't see this like in the capture below, try toggling the icons, there are different view modes. Now, going all the way down I found these. It doesn't look like that's going well. Obviously some kind of infinite loop in some random code:
I couldn't find out if it was an extension itself or some other bit of code. Clicking through I only could find // Copyright 2014 The Chromium Authors. All rights reserved..
Checking in Incognito mode clear of extensions, the website loads just fine.
I'd also advise to check the Console tab to see if there are were any errors that might cause the infinite loading thing. You'll often find clues there.
So i've been banging my head against the wall trying to figure this out, and it's about time I ask for help. I have a flash audio recorder that is displaying a popup to the user asking them to allow microphone access using:
AS3 --
Security.showSettings(SecurityPanel.PRIVACY);
Now, on chrome it works perfect! Everything shows up correctly and looks like this:
http://postimage.org/image/6e6ldfmpj/
Great. Now the issue is, on Firefox (and I believe IE9) it looks like:
http://postimage.org/image/mqp1kmcjj/
Notice how there are only 3 tabs in the second one (Firefox). Well, the second tab over is Privacy and allows you to "allow" or "deny" our website from accessing your mic. So it's a bit of an issue that that tab is not even visible... Any thoughts on that? I can't seem to find anywhere where anyone has had that same flash dialog box pop up with only 3 tabs.
Thanks in advance!
You can use [Allow][Deny] dialog:
It appears whenever you access microphone/camera by attaching them to NetStream.

As Sunil D. mentioned above, Firefox will not show some tabs in private/incognito mode. The problem is user can turn it on not only by opening new private window, but also by changing some regular Firefox preferences. Go to Firefox options, select "Privacy" tab and search for "History" group. There you will see a dropdown with "Firefox will:" label. There you can select "Never remember history" item and browser will show you a small tip:
Firefox will use the same settings as private browsing, and will not remember any history as you browse the Web.
Then your browser will be restarted. Further research revealed that Firefox really turns private mode on after such manipulations. Sunil D. and Jordan Reiter were both right - the problem can happen with users in private mode and problem can be solved by reinstalling Firefox with all it's configurations (including that history setting). Of course, it's much easier to ask users to change that setting. Also private mode detection with JavaScript can help to inform user about this expected problem.
When clicking on Build History in the Web UI of the Hudson CI, I get a list of builds that happend in the past. Fine.
But above that is a diagram, sort of a timeline that I can drag back and forth. But there is nothing in that timeline!?
What is supposed to be displayed there?
Not an answer perhaps, but it seems that this feature just isn't working
http://issues.hudson-ci.org/browse/HUDSON-6439
Just a touch up note!
Currently Internet Explorer displays this feature as blank...
But using Firefox I can see Dates (scrolling in this frame is enabled)!!! …but Dates only...
These dates start around (maybe a day or two before) the creation of the Job!!
