Web Browsers





Web browsers are applications used primarily to display documents, files and media from the Internet, identified by a Uniform Resource Identifier (URI) that can be a page, image, video or other file. Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.

This one takes the cake. I am obviously missing something obvious.


(1) Simple php program

// proj_summary_mu.php
include "db_connect_nb.php";
$pid = $_GET['pid'];
include "pdf_MU_project.php";
// use fpdf_merge to put together
include "merge_MU_pdfs.php";

Open in new window

(2) File pdf_MU_project.php attached.

Note there is ONE echo in this file. It never shows.

(3) The last few lines of pre_package_mu.php. This is significant, because the real problem shows this as the program being executed, which is NOT true.

	// do the project summaries
	header("Location: proj_summary_mu.php?pid=". $pid);
	//header("Location: package.php?pid=" . $pid);

Open in new window

(4) Browser display of code as run (attached) . Earlier today I had echos that show this; they have bee removed, I have checked source on the server, they are NOT there. I ran it in FireFox AFTER clearing the cache. Don't know how to clear cache in chrome. Ran it there, identical result

As best I can see, this is impossible.
How do I set the default browser via batch or powershell script in Windows 10? I need to override Microsoft Edge as the default browser and replace it with Internet Explorer for a customer. What would be the best practice for going about this?
How do I get rid of a google chrome extension called directionsfinder.co? I accidentally downloaded it when I tried to download Google earth on my windows 10 desktop. I used to have Norton 360, but now I have free McAfee through my cable subscriber. A Google search said it is a browser hijacker and a virus and that I have to reset Chrome. Will I lose all my other add-ons, extension, bookmarks, etc?
We have a few Windows 10 Machines running Chrome in Kiosk mode running a specific web site.  The problem is every once in a while we will get a full page add in a new Chrome window that covers the Kiosk web site we are using.  Any ideas?

I am trying to convert from Firefox (after maybe 10 - 12 years) to Chrome.

Is there a way in Chrome to put a left sidebar containing bookmarks?

Decent HP Desktop running sluggish, mostly due to Chrome and Edge.
- HP Desktop 5082vS3 (750-114), 12 GB RAM, 64-bit PC, Windows 10 (OS 17134.523). 1.7 TB storage free, HDD.

I posted essentially the same question recently and got good advice, but wanted to follow up. I've been studying Task Manager for several weeks, and did a quick comparison to work, which runs great. Both have HDD.

So it's definitely Edge and Chrome that are killing the machine, while my government runs great running 2+ times more processes (mostly Chrome, Edge, PL-SQL Developer, SPSS, etc.)

Malwarebytes is running, all green, and runs every day. I also have McAfee running, also all green.

After like two weeks, government PC was at 16% CPU, 74% Memory, and 0% disk,
running 84 Chrome processes and 41 Edge processes. Also has HDD (500 GB).

Home system grinds to a halt
running 34 Chrome processes and 11 Edge processes

But basically after 3-4 days at home and essentially light usage (at night, web surfing, etc.), it grinds to a halt.

I used Epic browser only this week, and it's been hanging in at 60% Memory, 10% CPU, 1% Disk.

With Chrome and Edge running, often CPU spikes to 100%, Memory often get to 90% and Disk often at 100%! So much so that after 3-4 days I'm re-booting.

From last post:

Chrome …
I realize I'm living in the dark ages, but how do I show source in Chrome?

I'm using the debug console

This is very useful, because my programs are almost all in php, I need to see the html, javascript so I can get the line numbers

Ok all the Google heads, dev guys, etc out there, Im looking for better ways to group my tabs.  I usually have around 80 tabs open in Chrome at work.  We're a Google shop.  Ive noticed that I have several groups that could go together, e.g. 8 Google docs, 7 of our portal, bunch of Google Sheets, etc.  Is there a better way to stay organized?  Thank you techs, Mark88tabs
Somehow, when I go to google.com, I now get this.


How do I fix that?

I'm using Firefox, I don't have time to try other browsers.

I have a simple form that posts to a page that process the information and inserts it into a database table.
for some reason some of my people are coming through duplicated exactly .

After much narrowing down the problem, and tracking the browser in the table, I see it's only happening in chrome. all other browsers are coming through once.

i looked in the network tab and the page is only being called once.
i put a die(); right after the insert so make sure it's not doing anything else, and the page stops, but I still get 2 inserts

What else might this be?  My page was working fine for months, and suddenly last week this just started.
 try {

    $dbh = $conn->prepare("INSERT INTO dbo.[ ... ] ( ........) VALUES (?, ?,?,?,?,?, ?,,?)");
	$dbh->bindParam(1,  $firstname);
    $dbh->bindParam(2,  $lastname);
    $dbh->bindParam(3,  $address);
    $dbh->bindParam(4, $_POST['city']);


			//catch exception
			catch(Exception $e) {

This is similar to a question I posted the other day, only this time, I want to be able to do the same thing with Browsers. Google hasn't been of much help.

I'm testing a variety of (5) browsers I plan to eventually do a review on, but in order to test them properly and to my own satisfaction, I need to keep switching the default Browser in Windows 10 using the GUI method in Default Apps. Too many clicks needed for my liking.

Is there a simpler way you know of that I could do the same thing with just a couple of mouse clicks, like the solution John found for me in my other question?

Ie: For my microphones, all I need to do to change the default Microphone to use is with one click of my mouse as shown below and it's done:

Example of the type of solution I'm looking for.
Similar to the above, I'd like to have a menu where I could just click and select any browser I want to make it the default browser in Windows 10 with one or two clicks.

Please note that I am heavily challenged when it comes to any type of coding, scripting or automating. A programmer I am not.

Using a GUI I can figure out how to do just about anything on Windows, but if I need to make changes via Powershell or similar, please include detailed instructions on how, where and why I need to enter any script(s) to achieve my end goal.

Any suggestions?

Thanks, Andrew
I need to know how, when using Chrome & showing the console section on the right (using F12), how to make it stop when it detects an error. It flashes a red error message & then proceeds. I can't see it, it disappears too fast. How can I make it stop on a javascript error (that's what I think it is) so I can see what it says?
how to remove google chrome for users in published Citrix desktop. Urgent. Need this solution by tomorrow. Thanks.
I want to pass username and password to a website login screen instead of the user entering the data.  Can this be done?
Our Internet Surfing Segregation (one of those  Secure Browser product/solution like
Menlo, Authentic8, Fireglass) recommended us to put a proxy.pac (Proxy Auto Config)
file in a webserver.

This proxy.pac will be pointed to by IE, Chrome, Firefox so that when users launch
these browsers, proxy.pac will launch this vendor's secure browsers when users
browse sites that are not in the 'whitelist' (ie trusted sites).

This is a Garrison product (garrison.com) : I thought of placing this proxy.pac file
in a corporate shared drive  so that in browsers, we can set in the proxy config
script as   file://c:/folder/proxy.pac  but IE11 doesn't support this file location
anymore (tho Chrome & Firefox still do).

Was advised by garrison that it's best to put in web server so that in IE11, can
specify as  http://...website.com/proxy.pac    but our corporate site is hosted in
a Cloud: don't think the Cloud provider (AWS) allows us to deposit a file in an
SaaS model.

What other ways other than setting up a webserver?  I do have a Solaris web
server that acts as  ClamAV depository (local mirror)  that runs httpd : what
are my best option?
Need a few ideas on how to code sample data to test my Kendo UI controls

I will be using Kendo UI, Angular and jQuery on my next project. So, I assume the client will have different Kendo UI controls to test. So, the best way to test them is to populate them with dummy data, since the back-end work may not be up to speed yet.

So, please provide one or more Javascript samples which I could use to store the sample data.

I guess a multi-dimensional Array is pretty common in Javascript, BUT, it would also help if you also have the Javascript wrapper which returns the sample set of data as JSON and XML.

Does Angular 7 NEED jQuery?

I will be starting a new project which includes:

Angular 7

but my experiences with Angular 4 showed me that when you think you need jQuery, you have not looked hard enough at solving the problem using the features of Angular.

But I see this association between Angular, Kendo UI and jQuery.


How do these all fit together?


I have installed Chrome browser and added an extension called "tinyfilter."  It is an internet filter that can block or trust sites.  When I add a website like cnn.com it will not block it.  I have tried many other websites and it will not work.  Any idea what I'm doing wrong or does it not work?

We receive an email about a vulnerability in chrome.  May someone advise what is the best way to remediate the issue?

Do we need to update chrome on all workstation?  If yes, how can we deploy the update from a centralize way such as using group policy?

Please advise.

Many thanks.

I am trying to add an export link on the nested datatable.  When I try to see my result on Chrome and Firefox, it is working perfectly.

The result on chrome and Firefox
<div id="nested-datatable-covertab_0_row_0_tab_0_row_0_tab_0_filter" class="dataTables_filter"><a class="export-circuits" href="">Export circuits</a><label>Search:<input type="search" class="" placeholder="" aria-controls="nested-datatable-covertab_0_row_0_tab_0_row_0_tab_0"></label></div>

Open in new window

On the IE, it removed the data from label elements.
<div id="nested-datatable-covertab_0_row_0_tab_0_row_0_tab_0_filter" class="dataTables_filter"><a class="export-circuits" href="">Export circuits</a>

From my research, IE has got some issue with jquery append method.

Any helps would be highly appreciated.
Attached is the screen that comes up in Internet Explorer 11. Where do you start trying to fix the error?

I am having trouble figuring out how to have modified css applied to an existing WordPress site.

- WordPress 4.9.9
- Apache

I would like to know:
- How to change the looks of the website

- I don't know which scss files are loaded by web browser. There is no scss files under application directories. You can actually find multiple scss files are loaded from the developper console.
- I have 'main.css' that seems relevant to scss files used to style the website. CSS properties can be found in 'main.css' but browser does not use 'main.css' to rendering purpose. Instead, it seems to use .scss files since look of the site does not change by modifying 'main.css'.

Other note:
- There seems no SCSS related plugins are installed.
- This WordPress website was developed by freelancers who I am not in touch anymore.

Live preview site:

I have been googling for long time, but not successful so far :(
Any advises are welcome. Looking forward to hearing from you.
