Firefox Support Forum

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?

When I type facebook.com into my address bar I keep getting sent to m.facebook.com/?refsrc...etc.,etc. Then when I log in from that address I'm at m.facebook.com/?_rdr, which is apparently what people with cell phones or iPads see. Why is this? What should I do? Thanks

Is there a way that I can bring Firefox back up without it restoring the open tabs including the one that is trying to take control of my PC ? I've looked at the solutions in the Knowledge base but didn't find one that matches this problem ..... Thanks in advance

Firefox, latest version, keeps logging me out of sites. I have tried all troubleshooting suggestions offered on the web that I could find, short of starting all over by resetting profile, which I do NOT want to do.

Anyone have any suggestions other than the standard ones about cookies, preference settings having to do with cookies, private browsing, deleting all cookies, deleting cookies files in profile folder, extension issues, etc?

Thank you!

Hi, everyone!

I found a similar solution but only for "Open link in new tab": you can go to about:config and change the preference named browser.tabs.loadBookmarksInBackground. But I want the same thing for my saved bookmarks on Bookmarks Toolbar. Sometimes I need to open a few bookmarks from one folder and then I used for it middle-click or click on Open in new tab, but it switches to tab immediately and I should repeat a process again: click on a folder, find a bookmark, click on it, new tab opened and so on. So is there an option to open bookmarks in background tabs? How can I achieve that?

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.

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.

I received a Firefox update message (refresh) last night. Without hesitation, I clicked. I was updated to Firefox 83.0 (32 bit). (FYI-I'm still using Windows 7.) Immediately after, I realized all of my logins and passwords were gone. A "Please enter you primary password to view logins and passwords" banner is at the top of the page. When you hit the login button, the banner disappears. (I'm already logged in.) I'm left with a "no synced logins found" message. I'm always signed into Firefox when I use a browser and save login information. Not to mention, the were there moments before I hit refresh.

Of course, I don't have passwords stored anywhere else and need to access a site sooner rather than later. (whomp, whomp) I've seen "logins.json" and "logins-backup.json" files mentioned in other posts. Is it safe to assume these magic files hold login/password information? If so, where do I upload?

Any help would be greatly appreciated!

Good evening. I tried to connect to Nespresso.com today and I can't from Mozilla Firefox 83.0 (64 bits) but it works from edge Chromium. What can I do? in advance thank you :)

I must have accidentally hit a very special and mysterious combination of keys, because all of a sudden the text in my address bar is justified right, and it's making me crazzzzzzyyyyy. Anyone have thoughts on how to get the text justified left again? Thanks!

I'm attaching a screenshot so you can see what I'm talking about.

THIS keeps on happening at least 6 - 8 a year. ive cleared the cache off Firefox, rebooted it, got a now TESCO site and it is still the same. Yet Google fires up all right all the time. I have got 3 pc of a type and they all can get TESCO without any trouble. Ive been with you for 20yrs and am reluctant to change noW. Tesco just say your better of using Google than Firefox, which isn't much help. Yes they can get me on (sometimes) but they all ways say Google is the one really.

There must be something i can do?

1) Because the built in options are ambiguous I want to flush the temporary Cache storage directory myself, but I can't find it. Where is it? 2) Then I want to relocate it, but here are Mozilla's instructions for how to reset it:

==

To set Firefox's cache folder, first type “about:config” (omit quotes throughout) into the program's address bar and then hit “Enter.” Right-click on any of the displayed properties, select “New” and then select “String” to display the New String dialog box. Enter “browser.cache.disk.parent_directory” into the box and then click “OK” to display the New Value dialog box. Enter the full filepath to the folder you wish to use as the cache folder, and then click “OK.”

Doesn't work.

So, after finding the current location and flushing it how do I change it?

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 was a long-time user of Menu Mod and did not update Firefox for years because it was phased out after V56. Now that I have updated to the newest version of Firefox, I cannot find a replacement for Menu Mod. Google recommends Menu Wizard but, that add-on has also been phased out. What add-on will allow users to edit the Firefox menus? And if there is not one, why? I am really regretting updated Firefox because of this.

I use firefox 83.0 on Ubuntu 20.04. Browser does not play videos on Twitter, Reddit or Netflix. Youtube plays some videos but some videos show error "your browser does not currently recognize any of the video formats available". I cannot find any viable solution. what should I do?

I installed chrome and it plays all the videos. So there must not be any problem in OS.

i receive this file from my antivirus as a potencial hacker tool , now is in quarentine mode on my computer . any idea to check or identify this ?

I am using Firefox Nightly. It receives updates every day, but most of the time I cannot restart Firefox as soon as update is available. I want to delay it till next natural restart (ex.: night), however, Firefox shows notification about the available update. It's a minor issue, but seeing notification every day and having it to close every time gets annoying very quickly. I want to disable update notification but keep automatic updates. How can I do this?
