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.

All Bookmarklets work on Chrome but some don't on Firefox.

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.

Hi:

I installed a few days ago the latest version of Firefox on my iMac. I am noticing that when I open a new window in Firefox, a tab is opened and it shows Search Pulse. I looked it up and it appears that it is some kind of adware that is dangerous and is hard to remove. I looked up some articles and they all seem to be written by some vendor promoting a product for removal. I am very concerned asking for more problems than what I have as I am not a technical person.

Did anyone encounter this adware and if so what's a trustworthy product to remove it?

I have Norton and the free version of Malwarebytes on my computer. None of these programs caught the installation of this adware.

Any advice would be appreciated. Thanks.

The problem began on Sunday December 6, 2020. I could no longer log in to my Charles Schwab Account with Firefox. On December 7, 2020 I called Schwab and suspected it was a problem with the Firefox browser. They had me log in using Chrome, which worked fine. Schwab said they would contact Firefox and let them know of the problem. I decided to also let you know of the problem. As of this morning, December 8, 2020 the problem still exists. Hopefully you can resolve it soon. Thank you.

Hi:

I am using the Safari browser on my Mac. Suddenly when I wanted to login into the Firefox account I got the 500 Error message that I pasted in the Subject. I am a new user of Firefox, just switched from Safari and I am not computer savvy...

I cannot login, I cannot create another account...

I hope I do not have to go back to Safari.... I have no idea what might cause this problem and what to do. I hope that somebody has the answer. Thanks in advance.

I have previously not had this issue, have had no problem viewing videos on this particular website. Recently I've had a raft of of issues (since the latest Firefox upgrade??). In this instance, the website is https://www.sbs.com.au/ondemand/ I am signed in as a member. Whenever I try to play a movie or TV show, I get this message:

Video Playback Error Sorry, we’ve encountered an error playing this video. If you have an ad blocker turned on, try turning it off or whitelisting our website before trying again. This may prevent you from loading videos.

I'm PC illiterate so I have no idea how to turn off an ad blocker (as well as Firefox being my browser, I have Quick Heal Anti-Tracker installed). Can someone please provide some help with REALLY BASIC instructions (ie. as if you're talking to an alien who has never used a computer before!). TIA

I also am unable to sign in to my YouTube account so I can watch videos I've subscribed to (I can view videos otherwise on YT). When I attempt to sign in, I get this image (below).

I have emptied cache, deleted browsing history etc, makes no difference. I can access and view SBS and YT on another browser, just not on Firefox.

Beginning just a few hours ago, Firefox is starting up in German, which I don't read, with a home page I didn't choose, as shown in the attached image. I've tried going thru the options to change this but nothing seems to help. I restarted my computer (Windows 10) and no difference. The version is 78.3.1esr (64-Bit) and says it is up to date. How can I get back to English and no home page (just an empty tab is my preferred startup)? Thanks for any assistance. (I tried searching for a problem like this in the help and came up empty.)

A computer support tech did some "housecleaning" on my computer yesterday via Remote Access. After he finished, I had to re-do Firefox (among other things) from scratch: settings, extensions, customizations, etc. Another difference I noted is that when I mute or change the volume on my speaker, a control panel appears in the upper left-hand corner of the screen next right next to the mute-to-100 volume slider. (See attached screenshot.) I know there's a way to turn that panel off without affecting the volume slider because I was told (here at Support) how to do it when I first began with Firefox. However, it was a long time ago; I don't remember what I did. I think it had something to do with config: then changing a setting from on/1 to off/2 or something like that. Will someone please help again? Thanks in advance. :)

Today I kept getting the above error message when I tried to log on to Halifax online banking. I do not run a VPN. I cleared the Halifax cookies. I rebooted my router and I rebooted my laptop. I still get this error message. However I can log on OK if I use Chrome so this must be a Firefox issue. Any other suggestions?

Several months ago, I was not able to access my contacts or calendar. In other words, no response when trying to click on any of those icons. However, I tried a different browser such as Edge and everything worked fine. So.....am I going to have to change my default browser. It kinda looks like I will use Edge from now on. Any thoughts........ Use Yahoo mail.

When I opened Firefox I received a "news message" that makes no sense to me. How can I revert Firefox to its former usefulness? There is something about the former installation of Firefox being undisturbed, but I cannot find that installation. Apparently this has something to do with sync-ing my desktop Firefox with other installations -- I've less than zero interest in sync-ing.

What happened to the bookmarks I had stored in the bookmark bar? How do I get those back?
