Hi- a computer tech here replaced our hard drive, which was crapping out. He said he moved everything over, but we had to download and reinstall Thunderbird email client and Firefox.

The problem is, we don't have the bookmarks or histry in FF, and we created a new profile in Thunderbird, but we don't have any of the old folders or sent emails.

Now, we do have a macrium reflect image which I can browse, from just a few days ago. I copied the profiles from appdata into each of the profile folders on the new C drive.

But still no luck. What am I missing? Thanks!
Using Outlook Web Access (OWA) to an Exchange 2010 server with Firefox. In the compose new message window I am unable to attach a file. I click the paperclip icon in that window's toolbar and get no response. The other buttons on the toolbar are also unresponsive. It is not a problem with other browsers and it also works in Firefox with the "light" version of OWA. I tried removing any popup restrictions but it didn't help. Seems to have started recently, presumably after a Firefox update. I have also tried updating the Exchange server without effect.

What could be the problem? Where should I focus my investigations?

I have been using MalwareBytes for many years.  I purchased the product and have the Premium version installed.

I use Firefox as my browser and the Google 'www.google.com' page as my search screen.  

This combo has worked perfectly over many years but now I'm getting these popup on every search I try from the Google page.  It does not happen when I try to search form another page such as MSN.

This is only happening in Firefox.  It does not happen when I google search from with Explorer 11.

I load a php generated html page in the browser & it just get's stuck. Nothing shows on the page (in the browser). I have tried it with FireFox & Chrome.

Some clues:
 This code is at the VERY end of the document (obtained by "view source" in Firefox).
nosumm = "1"
	if (nosumm == "1") {
		window.location = "send_email_ls250.php?ddocs=" + ddocs;
	} else {
		document.getElementById("container").style.visibility = 'visible';

I'm expecting it to drop through and execute this javascript, seems like it doesn't.

Can that be happening? It's ignoring the last <script>.

As a reference, I attached the COMPLETE HTML file.

Hi Experts,

I just recently purchased a MacBook Air for myself to learn more about the operating system and how to use it, so my knowledge of how to configure things in it is pretty elementary, if non existant.

I have a problem I can't seem to find a suitable solution with google. On my install, I have 3 icons that appear as Question marks instead of their icons. Please see example image below.

Icons are a Question Mark
Can anyone explain how I can resolve this, so that the Grammarly, Firefox and Skype icons appear as they should?

Please note: Including any screenshots with your comments if possible (that you think may be helpful) would be a real bonus for me and much appreciated at this stage of my learning curve ;-)
Hi guys

In October, our Symantec EV SSL certificate will be dis-trusted in Chrome and in Firefox, meaning anyone who visits our website will get a certificate error before being able to browse the site. Not great for an ecommerce website!

The current EV SSL certificate is due to expire in December, but to avoid this issue, we’ll need to renew by October 16th at the very latest.

We have two options:

1.      Purchase a new EV SSL certificate from a different provider, such as Comodo.
2.      Switch to using the wildcard certificate that we have for our website. This will mean we no longer have an EV SSL certificate for .

Option number 2 is the cheapest and easiest option, but it means we lose our EV SSL certificate, including all of the security and visual elements of this (such as green browser bar). This apparently affects conversion, as greater customer trust in the website means they are more likely to buy.

Any alternatives or suggestions that you have?

Thank you
My company redirects a user based on if they are logged into Facebook or not. But we are having cross browser issues and I need another set of eyes.

Firefox blocks the connection to Facebook if tracking protection is on, not sure if I can get around that. I just need a popup to open even if login status fails. I tried a delayed meta refresh and that didn't even work.

	  window.fbAsyncInit = function() {
	    FB.init({appId: '' . $fb_app_id . '', status: true, cookie: true, xfbml: true});
	    FB.getLoginStatus(function(f) {
		if (!f && f.status) return;
		       if (f.status == 'connected') {
				var url = "http://google.com";
				url = new URL(url);
				window.open(url, "_self");
		        } else if (f.status == 'not_authorized') {
				var url = "http://google.com";
				url = new URL(url);
				window.open(url, "_self");
		       } else {
				var url = "http://gmail.com";
				url = new URL(url);
				window.open(url, "_self");
	  (function() {
	    var e = document.createElement('script'); e.async = true;

I'm having an odd pop-up problem with Firefox (61.0.2 64-bit on a Windows 10 system). Only on a few websites, a pop-up appears covering most of the screen with the rest of the web page visible but darkened. The pop-up has an "X" in the upper right corner but clicking it has no effect. The pop-up cannot be closed. The underlying web page may be read by scrolling it "beneath" the pop-up. The only way I have found to remove the pop-up is to close that tab on Firefox.

One website where this happens frequently is www.njmonthly.com, especially when looking at a restaurant-review page on the site. (It can take a minute or so for the pop-up to appear.) Attached is a combined screenshot showing the complete webpage with the pop-up present and the Firefox detail for the pop-up image.

Restarting Firefox with all add-ons disable has no effect.

Does anyone know how to get the pop-up "X" active so the pop-up can be removed?

Thanks, Pete
Summary: Firefox does not display some web pages properly on Windows 10 64-bit PC. Significant troubleshooting already done. Looking for a solution.


I am trying to come back to Firefox after getting frustrated with Chrome. I installed the latest 32-bit version (64.0.1) although I also saw the same problem with the latest 64-bit version (now uninstalled.)

The New York Times (nytimes.com) home page displays properly. Pages inside their website do not display properly. I see the page briefly and then it disappears and the browser window is entirely a white screen. The pages display normally in Chrome and Internet Explorer. Here are some example URLs:




This also occurs with some other web pages. For example, on the following page none of the text displays on Firefox:


Clicking the Read Mode icon produces a mostly-blank page with the statement that the file failed to load.

There is no redirection – Firefox does not forward to any other page – it just displays a blank page with the expected URL.

The only extensions installed are: AdBlock Plus, Copy PlainText, LastPass. The only plugins installed are OpenH264 and Widevine, as automatically installed by Firefox.

I have a crashed computer and I have pulled the hard drive and plugged it into a device and I can see the hard disk now as a drive letter and on another computer and I can access all files.  Is there a location that I can find firefox, IE, and Chrome bookmarks?
I need to get into a test server that that has woocommerce on it.  Originally it had an ssl cert but now it doesn't.  I keep getting this error in Firefox 61.


I have tried this in other browsers too and get a similar result.  I have access to the db and I have removed the https from the site url and the home link.  I have deleted the cookies corresponding to the url I am using to access the dashboard.

Searching wp_options for ssl I get these rows - https://gyazo.com/7abe7622428cf1c648f5bab0a4d4773f

I did use Really Simple SSL as a plugin but don't know how to turn if off with access to the dashboard.

I just need to get into the dashboard and check some settings.  Can anyone help me get into my dashboard?
Hi Experts,

Each year I have data in an Excel 2007 spreadsheet which I want to enter into forms on several webpages for filing tax.  No logging in is required.
The solution will need to give me the opportunity to manually check the entries made on each page before submitting it (but if I find a problem I'm willing to abort, fix it, and restart if needed).

This is the first webpage that needs to be submitted:

I don’t think I’ll bother posting my input data (the spreadsheet) because its layout is flexible and I don’t think we need to get into that level of detail.  I am a programmer, but I’m wanting ideas on what tools to use, and the basics of reading the data from the spreadsheet and transferring it to the webpage.  Maybe a bit of code to get started would be helpful.

Would AutoIt be a good choice for this?  If so, should I basically follow this tutorial from 2016, installing the extra bits of software recommended in it?  If so, how would I read the data from the spreadsheet?
Or would iMacros but a good choice?  I would have thought it wouldn't.

Environment & limitations:
-      Windows XP (yes, all the latest technology).
-      Firefox 52 ESR.
-      Can’t use IE (which is version 8 and can't be upgraded in XP) because the webpage doesn’t seem to support it.
-      I’m only interested in free options.

Hello Experts,

Does anyone  know of either a paid or free service that lists high-risk private VPN services? We would like to see if there is a good one to use to integrate with our firewall. BTW, my suggestion was to put a WAF up I have been asked to explore IP intelligence services first.

Thank you,
Still struggling with php/mySQL/ajax registration script. Now getting CORS error "Cross-Origin Request Blocked"  This may be FF issue because I'm not getting the error on Chrome.  I'm not clear why this error when everything is within pricelearman.com. Also, I tried to suppress the error by pasting in the .htaccess file recommended by H5BP.  In the end, my script is able to connect with the database, but no data is uploaded

I have an issue accessing Youtube. When I enter www.youtube.com in the address bar, I am redirected to google.com.
I tried this with Firefox, Chrome and IE. I can not see embedded videos either.

Same problem with vimeo (redirection to google.com as well), but no issue with dailymotion.

Note: google.com is not even my default homepage !

What could be the problem ??

Thank you for your help.
