My website project uses html, PHP, javascript, css and mysql. My page is always fullscreen. (so no browser bars etc) Everything that is being displayed, is controled by my code. However...
My page reloads a php page in an iframe every 0.5 seconds. (and more might be added) When the page is loading, I get a "connecting with 192.168.XXX.XXX", or something scimilar, in the left bottom of my full screen. How do I disable these kinds of messages?
Most of my buttons are already javascript functions, since they have to do multiple things, but with a href=, I also get that same display in the bottom of my browser. This really screws up my full-screen layout.
Things I've tryed: google, and changing z-index of my images, in the hopes it would cover up this "connecting with" info box.
I would like to get a CSS/javascript solution for this problem. If I need to change browser settings with the "about:config" page in firefox, that is also fine.
*PS: English isn't my native language, and my browser is also in another language then english. Tryed to find a solution on google, but could not get any relevant info, not even the name of that bar.
As far as I know, it isn't possible to fix this problem using any code on my web page. It is browser related.
Finding some help at the mozillazine.org forums, got me to some good search queries.
If you want to remove the status bar (that's what it's called), you can use the plugin "Status-4-evar". It gets you the ability to turn back time, and get some lost functionality back into firefox. It also allows you to disable the status bar. However... When in full-screen, firefox (version 43.something) then puts back the unwanted status bar, even if the plugin/add-on should have blocked it.
Second solution should be to create a userChrome.css file, and put it in some directory in your firefox profile. Finding this directory using the mozilla KB was really frustrating, since it isn't correct/out of date.
Correct location for your userChrome.css file should be:
C:\Users\XXXX\AppData\Roaming\Mozilla\Firefox\Profiles*random string*.default\chrome\
c:\users\XXXXX\ could be different on other windows versions. The chrome folder might not excist, so just create it.
Then create the userChrome.css file, if it does not excist already, and add the following tekst:
#namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */
.statuspanel-label {background:#FF9!important;color:black!important;font-family:"DejaVu Sans Mono"}
statuspanel {display:none!important}
statuspanel {max-width:90%!important}
statuspanel[type="overLink"] .statuspanel-label
statuspanel[type="status"] .statuspanel-label[value^="Looking"]
statuspanel[type="status"] .statuspanel-label[value^="Connect"]
statuspanel[type="status"] .statuspanel-label[value^="Waiting"]
statuspanel[type="status"] .statuspanel-label[value^="Transfer"]
After having done that, restart your firefox, and all status bar messages will be removed, even in full-screen.

I've been working on a CSS / HTML drop down navigation for my blogspot.com site. After coding it a few hours I had accidentally closed the tab to find out no matter what or where I tried the CSS on blogspot, the CSS wouldn't work again. Now, the HTML/CSS works anywhere else, just not on blogspot anymore.
These are the things I did:
1. Created a entire new blog under the same account, then applied
html/css
2. Cleared cookies, cache and restarted browser
3. Tried multiple browsers
4. Used stylish extension to override
5. Used console in firefox to edit HTML on other sites and added my
code to see if it worked elseware
6. Used a different computer
7. Used mobile network instead of ISP
Despite doing everything pretty much to get the css/html to work blogspot, it will refuse it now no matter what. I am guessing it is obviously an issues with blogspot.com such as a glitch or bug that I may have now caused. It also shows a lot of CSS code struck out in the styles inspector when you inspect a site via right-click.
I dab in javascript / jquery sometimes and I am wondering if there is a way to force my CSS to force override.
CSS/HTML http://jsfiddle.net/rpksx66u/
My blogspot site: https://vitalintel.blogspot.com/
Im about to pull my hair out.
update: so I moved the css/html/script element to another part of the page and it works. When the element is placed in the Cross-Column's sections in layout, it refuses to use any CSS.
My Angular 2 Application is slow to respond (1-5 seconds) to key input, button clicks, tabbing across inputs, etc. only when Chrome Developer Tools is open. Material 2 animations also become slow and choppy.
I've been developing this application for three months, and use Chrome DevTools every day. This issue cropped up seemingly overnight.
What I know:
I stashed all pending application changes to revert my application to a time when this was not a problem. The issue persisted.
Chrome DevTools doesn't seem to slow down any other application (ie. google inbox, google maps) in the same browser session.
Maddeningly, when I run the DevTools' Timeline "Record" to try to gain visibility into the issue, the issue disappears and the page reacts at normal speed again! I assume this is the best clue that I have, but I don't know the internal workings of DevTools well enough to know how "Timeline Record" changes things.
I've restarted Chrome and deleted all cached data.
Nothing of the sort happens in Firefox or IE when I open the Developer tools in those.
Any recommendations on where to look next would be greatly appreciated!
Final answer:
Remove all breakpoints
Even if they're not getting hit this fixed it for me and got performance back to normal.
May be a bigger issue if you have logging breakpoints - so try deleting those first if you're attached to your breakpoints.
Previous answers:
I came up with a workaround - although still not really figured out what is actually wrong.
I also discovered a bunch of tools I didn't even know existed that I'd skipped over before - they're under More tools.
Start by opening the Performance Monitor. This shows a nice CPU graph isolated for your Chrome tab - the Windows task manager is as useless as it ever was.
This is the behavior I got when choosing a date from mat-calendar. No other logic running - just selecting a date. I removed everything from app-component and just put a mat-calendar and it took ten seconds to change the date!
Other controls are generally fine. I could open dialogs, use combo boxes etc. and nice and fast. But selecting a date gave me this nonsense:
I tried emptying local storage, clearing cache, etc. and then I changed port number for my website. I simply changed dev.example.com:44300 to dev.example.com:44301 - in other words Chrome now thought it was a different website.
This is what it looked like after I switched port number.
I also got the same effect using a reverse proxy server - which put my local machine on the internet - so I could try to duplicate the issue from other machines. I could not.
So hope that helps someone - still no clue what's in the cache for this server that is having such a massive impact on performance. But for sure it's not just my code.
Here's a few other things to try:
Test with --aot flag
This didn't make a difference to me, but good to narrow things down.
Add some controls that don't do anything (as a control)
This way you can find if some specific action or control is causing the slow down. You should of course be able to toggle these instantly.
Just toggle them on and off, hide something.
<mat-radio-group>
<mat-radio-button [value]="false">
bloop
</mat-radio-button>
<mat-radio-button [value]="false">
bloop bloop
</mat-radio-button>
</mat-radio-group>
Enable Rendering debugging options
Make sure you aren't re-rendering the whole page constantly
The rendering option above will show this to some extent, but one thing I like to do is just add a random text box - type in it and if the text subsequently disappears you know that control has been rerendered.
<!-- yes, just a standard text box -->
<input type="text"/>
Just hide things with *ngIf="false"
Hide controls (yours and third party) and see if anything is causing problems.
For me I'm currently suspecting mat-calendar is causing issues - but I'm still thoroughly confused as to why enabling 'Record' makes the problem non existent.
I've fixed the issue, but I'll never know what was causing it. Likely a setting that I had accidentally changed.
I deleted the Chrome App and reinstalled, everything is back to normal. I'm going to leave this question open in case anyone else has this problem or wants to contribute.
It is normal for every web app to run slowly with Chrome dev tools opened.
Especially if you have inspect tab open, that it's like a new page opened in the same time + has animations on any block render.
We had this issue today at a colleagues workstation. Turned out that it was a chrome-extension (don't remember, something with "ghost" in its name). So maybe try out using guest-mode and check whether the issue still occurs. If it doesn't, successively reactivate the extensions to see which one is causing the problems. If it still occurs, follow the other proposed approaches.
I have checked through a number of similar questions from the past. There have been quite a few suggestions from back then (like this, this and this ). I am now required to build an application that needs to show a popunder window (this is not an advertisement, but part of the site's utility).
I tried all the suggestions from there, but it doesn't seem to work any longer. Is there a way someone can help me out with how sites like setmp3.com continue to show popunder ads? I am unable to find the actual script in the source
That's basically it. Somehow, the javascript in Google Docs can turn off the default headers and footers showing the URL, date, page numbering, etc.
This only works in Google Chrome. When Google Docs is running from another browser it will print the headers/footers unless removed manually through the print configuration dialog. In Safari, it seems to generate a PDF server-side which of course will print outside of the browser.
I've searched around the web and have found nothing on how this is done. The javascript in the page is of course minified and obfuscated so it's difficult to get any insights from there.
So before I'm forced to dive into that spaghetti, I'd like to know if anybody has any ideas of how this is done.
After delving into some source code I found on a web page that has also resolved the issue (not Google Docs), the secret is the following CSS:
#page
{
margin:0;
}
This only works on Chrome, and perhaps Opera though I have to verify if the latter is true as it's printing the background color by default while chrome prints with a white background and the colored background in my page might be just obscuring the header/footer text.
Other browsers give differing results:
Firefox and Safari ignore the margins apparently and print the headers/footers anyway.
IE9 makes a mess of things and the contents print overlapped with the header/footer text. Poor browser always gets all the heat...
In conclusion, combining this with silent printing coming out in Chrome 18 kiosk mode will make for some interesting functionality, such as mail merge capabilities right from the browser though I still have to research how secure kiosk mode is though, as navigating to a malicious page runs the risk of exhausting printer ink and paper.
Navigation should be restricted to a URL white-list in this case.
If you go to this site, you'll notice a big image in the middle.
If you inspect it, you'll see this.
<img src="http://s3.amazonaws.com/mosaicimages/hmn58067pa">
If you hover over it during Inspect mode, you'll see this:
img[480x640]
And that's normal. The picture should display.
But sometimes, when I browse my site, the image simply does not display. The HTMl is the same. Everything is the same. It's just that the "cache" messes up.
This is what it looks like: http://i52.tinypic.com/1190xu0.jpg
When the image doesn't display, I clear the cache in Chrome browser settings, and the image displays again. After browsing the site again, random pictures disappear.
It's weird because when you inspect it, the code is the same. However, the image says:
img[0x0]
That's very awkward, because the image really is there. it's in S3 and it's fine.
It happens on other pages as well, not just this page. It happens for all images that are in S3.
Some of you may not be able to reproduce it. Some of my friends reproduce it. but if you can, please help, thanks.
Edit: I found a few bug issues related to Chrome? Is this it?
http://code.google.com/p/chromium/issues/detail?id=67373&can=1&q=image%20304&colspec=ID%20Stars%20Pri%20Area%20Feature%20Type%20Status%20Summary%20Modified%20Owner%20Mstone%20OS
http://code.google.com/p/chromium/issues/detail?id=68622
Edit: everything works fine in incognito mode.
Do you get the following warning in the console?
Resource interpreted as [something] but transferred with MIME type [something else]
It may happen if an image is loaded dynamically (i.e. img src changed at runtime on the client) - which was nicely responded to here.
This could also be caused by the browser actually receiving an incorrect MIME type declaration - I don't imagine that would be an S3-specific issue (given the apparently wide range of similar problems encountered) and would rather suggest it could be an issue with a forwarding (corporate?) proxy etc. - this was the case for us when including fonts but never with images.
Google chrome has an excellent report issue located in the settings tab, take this issue to them,atleast they will rectify in future release chrome versions.
