Firefox Support Forum

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

How can I completely remove the tab bar and regain 3/4 of an inch of screen space. It would be nice if Mozilla would just have a on/off button for it. I've tried creating a folder called Chrome within my Firefox Profile folder. I then created a text file within that folder and named it userChrome.css. I put this string in the text file #tabbrowser-tabs { visibility: collapse !important; } This did not work, does anyone know the best method for getting rid of the annoying tab bar?

Thank you

Hello,

I've just downloaded firefox, making the switch from chrome. Doing so I've migrated a couple of tabs and extensions I had. Totally it was 50 tabs, with 6 extensions, I've downgraded now with the switch and it's only 37 tabs and 2 extensions, even so firefox is using more ram than google by a large amount. With 50 tabs open, chrome was using 1.5gigabytes of memory. With the same 37 tabs and extensions, firefox is currently using 6 gigabytes of memory.

The tabs used are from reputable sources, so firefox shouldn't be breaking on these websites. The extensions I am using at the moment on firefox is, Ublock origin, Dark Reader.

As far as reputation goes, firefox should be using less Ram than chrome. Is there a setting I should know about to lower such performance issues? Firefox acceleration is ON.

Thank you for any answers.

A website MultiSafepay.com has saved my CVV number in Firefox.

How do I edit the autofill data?

I can't get to the same payment page, to be in a position to delete it.

Most links on this matter refer to:

 Options => Privacy & Security => Forms and Autofill

However in my Version: Firefox 98.0.1 (64 bit) running on an up to date Windows 10 this feature is missing or deprecated.

Can anyone say how I could edit/delete this specific entry, or point me in the direction of where this data is stored?

In the mean time I can't recommend using Firefox for entering critical security data, where websites can allow the storage of CVV numbers.

I'm a little surprised they've taken away the option of choice when it comes to downloading files. But what's most annoying, is the manager opens u and drops down blocking my view of the page, much less that it makes ms stop and think about what I am about to download.

I do not understand the purpose of this. The old way was safer, cleaner and less annoying. How can, or am I able to get that "choice" back?

When searching for a fix I have seen that that there is/was a similar feature in the Edge browser but it can be undone. I feel Firefox users deserve that option.

Thank you.

Thank you.

Just lately I have been finding that, for a few websites, they are unusable because the screen looks extremely blurred. I have attached a screenshot. Compare this with what you see at ba.com.

I am wondering if this is caused by a new secure feature of FF which is incompatible with these few sites. Really, any suggestions would be welcome. Otherwise I have to use Edge..

I need to disable this horrible translator that is now showing up on top of every page I visit, It keeps showing up even after choosing a translation or disabling translations for that language. That is probably a bug, but I don't want to wait for a fix, I need to be able to see the pages I visit completely, this thing prevents me from clicking buttons and and is really anoying.

This is the built-in translation feature since I do not use any translation plugins, and started showing up after an upgrade.

Hello How to remove extension symbol from toolbar? ^(see image): https://i.imgur.com/2bh8se5.png Any idea? Thanks

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

Hello all. Since the update to Version 113.0 I have been getting an error in my Event Viewer which is Event 2 Firefox Default Browser Agent . I am now on Version 113.0.1 and still get this error. Firefox is my default browser. Below is an image of what I see in my Event Viewer and also the full view of the event itself. I seem to not be having any problems with the browser but I was wondering if anyone could shed some light on why this is happening or forward to the Devs.

Respectfully, Don

I just reinstalled my operative system, and with that my Firefox settings got reset. I know there is an entry in about:config to prevent ads from opening new tabs and pop ups without authorization, even from legit websites like the login pop-up windows when doing a sign in in Google, in those cases to allow the windows it's needed to click on the lock icon next to the URL bar and allow it from there. The problem is that I don't remember the name of that setting and I have spend an hour looking for it on Google.

I had the same problem like the link below when I use firefox.

https://www.reddit.com/r/firefox/comments/tjxh7s/videos_freeze_when_window_isnt_in_focus/

So, did what the instruction says and it solved the problem regarding discord.

But, since I changed that setting, firefox doesn't remember my google login or dark skin settings of other websites (it was always automatically logged in when I use YouTube. Not like it remembers the password).

How can I solve it? I resetted firefox multiple times.

The latest example is the button to sign into LinkedIn. It is not working in Firefox, but it does in other browsers. I have other examples just from today. I have used firefox as default for many years. I assume this is a security thing, but these are basic links. I have no add-ons or other complications. Most times, I do not even realize there is a problem, but when I feel something is wrong, I try another browser and it works. Thank you.

I'm trying to take off this "Extension (Tabliss)" tag on my url. I have followed the instructions down below from another Firefox support forum: https://discourse.mozilla.org/t/make-addressbar-text-extension-name-of-the-extension-shorter-or-hide/28026/3

The instructions I followed are listed below:

"Users can apply custom style rules to modify Firefox’s toolbar area by creating a userChrome.css file. This takes about 10 minutes so when you have time to take it slowly and carefully:

(1) Set up your chrome folder and userChrome.css file following the five six steps in this article:

https://www.userchrome.org/how-create-userchrome-css.html 45

I have a boring video there if you like demonstrations.

(2) This is the code to paste into the file. You can edit the file using Notepad or a better editor. Make sure to keep it in a plain text format with a .css file extension (not .css.txt).

See improved rule down in: Make addressbar text "Extension (Name Of The Extension)" shorter or hide

/*
   Hide Extension Name in the identity area unless
   hovered for half a second (updated for Fx80)
*/
#identity-box.extensionPage #identity-icon-labels,
#identity-box.extensionPage #identity-icon-label {
  visibility: collapse !important;
  transition: visibility 250ms ease-in-out;
}
#identity-box.extensionPage:hover #identity-icon-labels,
#identity-box.extensionPage:hover #identity-icon-label {
  visibility: visible !important;
  transition: visibility 250ms ease-in-out 500ms;
}

(3) Firefox should read the file at its next startup and apply it to every extension page you load."

Edit: So, yeah, I need help getting this tag off. I'm new to Firefox so it could be something obvious I'm missing. I have also tried CTRL+SHIFT+R to reload the page for changes and also closed and reopened my Firefox entirely.

Thanks in advance.

When I am watching a TV stream on my PC; when I hover on (some) pictures or videos, a supremely annoying pop-up url appears at the bottom of my screen. I have some learning problems and can not figure out the 'userChrome.css' method. I can not work with long streams of multiple overlapping instruction. I am not tech savvy. I do not understand 'layers' and stuff like that. I can do the 'about:config' thing, if anyone knows whether or not if I can fix it from there, I would be eternally grateful. Thanks.

How do I create a TLS 1.0, 1.1 exception in Firefox 100.0+ for my legacy devices (NAS), that no longer get firmware updates from the manufacture, that are on my private network and thier configuration is done through a web browser?

 I have been using Firefox browser for a long time, since it was called Mozilla browser.  An answer such as "I'm out of luck." means I will have to look for a new browser.  I prefer not to do that.  I trust the Mozilla brand and like you products and recommend them to my friends and customers.

Does anyone know how to configure Firefox to stop the annoying google log-in pop-up? I've seen others ask the same question, but I have not seen any functional answers. I've never had a google account, for anything. I don't get the pop-up with other browsers, like Falcon or Brave. It's just a problem on Firefox. I appreciate you help!
