I can't access https://www.barnesandnoble.com/ without getting the following error message:

Access Denied. You don't have permission to access "http://www.barnesandnoble.com/" on this server.

I've tried to clear the history/cache and also turned off vpn.

It just happened, it was working a few moments ago.

Any help is much appreciated!

I followed the instructions on the support pages to transfer my profiles from an old W7 laptop to a new W10 one. After the copying of the profiles to the correct locations neither Firefox nor Thunderbird would start complaining that they could not find the profiles.

What I did (same thing for Thunderbird) 1. Opened Firefox troubleshooting on the old W7 laptop, opened the profile folder. 2. Closed Firefox 3. moved two levels up 4. copied the Profiles folder to a usb drive.

On new W 10 laptop 1. Opened Firefox troubleshooting on new W10 laptop, opened the profile folder. 2. Closed Firefox 3. moved two levels up 4. renamed the existing Profiles folder to Profiles OLD 5. copied the Profiles folder from the usb to the same correct location on the new laptop

When I tried opening Firefox on the new laptop it would not open complaining that it could not find the profile. Firefox had opened correctly previously.

Then when I renamed the moved Profiles folder to Profiles NEW and renamed Profiles OLD to Profiles, Firefox opened normally on the new laptop.

Identical procedure and result with the Thunderbird profile transfer.

What should I do?

Thanks.

I'm trying to understand how AWS pulls a file from a client device after I post an upload request to AWS S3. HTML is asynchronous and I can't figure out how, after I post the file name and such, an upload is started.

I’m uploading images from a user’s device to a S3 bucket using a HTML form. Everything is working fine but I don’t understand how the S3 server can initiate an upload from a client browser after the form data (file name, signature, policy, etc.) has been posted to its URL. The image data is in a file on the client device and is not contained in the form, only the file name is there. Where in the process is the upload started and how does the S3 server tell the client browser to upload the image data?

Perhaps there’s more communication between the web server and browser during a post/response that I’m not aware of. Perhaps AWS and Firefox have a WebSocket open to perform the file upload?

Any insight would be appreciated.

Firefox's ad block icon used to show up on my toolbar. Now it has disappeared and the only way to disable it for some sites is to go into ad-ons and turn it off completely. Where is the icon?

I've started using the beta version of firefox relay. I was wondering if the same alias can be used for multiple different websites? I have used it to login to one website already. Can I use the same alias for another website?

I use Scenesource to download items of interest, after scrolling down to find what I want, the settings do not allow me to get to the last page I started from and goes back to the first page. I know that I found the setting before but at my age I cant seem to get to it anymore. Can someone tell me how to get that back?

Recently, every time I go to YouTube on Firefox it only half signs me in. When I sign in, the home page of YouTube will look normal until I click on one of my playlists or the "add to watch later" button on any video. Then, it will ask me to sign in again. This only occurs on Firefox, other browsers are still fine. And, I've already tried refreshing Firefox, clearing my cache, and reinstalling. Any ideas?

I have a Bookmarklet that draws a red border on all elements in the web page.

` (function(){

   var e = document.querySelectorAll('*');
   var el = e.length;
   for (let i = 0; i < el; i++) {
           setTimeout(() => {
               e[i].style.border="1px solid red";
           }, 100);
   }

})(); `

This works fine on Chromium-based browser, but when I run this in Firefox it starts drawing borders and then all of the sudden a number gets written on the page. Everything is gone and a number appears.

I don't know why this happens, every other Bookmarklet works fine. It might be the script I wrote but I doubt it because it works completely okay on Chrome.

Running this snippet directly inside the console works fine.

How do I get rid of the extremely annoying and useless "Other Bookmarks" folder which I NEVER use? This forum is misleading because it says only 3 people have this problem. I'm sure there are many thousands but it is almost impossible to comment or reply. It was a major puzzle for me to get this far. Firefox should to make a simple list of bookmarks available, when you have the Bookmarks symbol on the toolbar. It should be the default instead of hiding them in "other folders". If someone wants to make it more complex they easily can add folders. The default now is too complex and difficult to change. Every time I need to add the Firefox browser to a new operating system I need to do extensive research and fiddling just to simplify because I cannot remember the gymnastics I had to go through the last time.This time it made me so exasperated I nearly gave up went to Edge.

i use google docs for school, and because of that i need to use sub and super scripts often, google has decided that CTRL + , is the shortcut but this also zooms in the page.

What did Mozilla do recently to screw up Firefox?

On some websites (e.g., https://www.usbank.com/index.html and https://www.penfed.org/) which I commonly visit, I suddenly start getting error messages when I try to log in ("Your username and/or password are incorrect. Please try again." on the U.S. Bank website and just "FAIL" on the PenFed Credit Union website). I can log into both without any problems using the Chrome browser (which I don't like using). I have called both U.S. Bank's and PenFed's website support departments (having spent over an hour talking to each one) and both claim that there's nothing wrong with their servers, websites, or web pages, but instead lay the blame on FireFox; I'm starting to believe this, since I can log into my accounts using Chrome without any problems. This problem just started (for me) two days ago. And yes, I cleared all of my history, and I also shut down and re-started Firefox.

So, with this background, What did Mozilla do recently to screw up Firefox?

Hi. I am trying to reach a site that I have in the past found a good reference site (if you like reptiles), Ian's Vivarium. I am in up-to-date Firefox for Win10, I have refreshed Firefox to no effect. Error message on the website is: "You are running an unsupported PHP version. Please upgrade to PHP 7.1.3 or higher before trying to install or update to phpBB 3.3" at the top of a wholly blank page.

I get the same error when attempting Chrome and Edge (which crawled back onto my PC uninvited)... maybe a website issue?

Help?

While not totally computer illiterate, I'm pretty close....

Thanks in advance?
