Firefox Support Forum

If the firefox screen is maximized on my laptop, there is a white bar that appears at the bottom of the second monitor I am using, It goes away the moment I minimize. This is a problem only with firefox and no other program on my PC.

Hey guys,

I think that my question is clear from the title :D ... but i will explain it.

I'm trying to make a program to change Proxy IP . I made it to change Google Chrome and Internet Explorer Proxy but Firefox Proxy didn't change.

I tried to change Firefox Proxy from :

C:\Program Files\Mozilla Firefox\defaults\pref

but I can't change the proxy so please, help me to edit Firefox Proxy settings using C#

When I try to login at the bottom of any Mozilla article page with my valid Mozilla account credentials (the same ones to login to my account on my Firefox browser), it gives an error message as if I had entered an invalid username or password (I had not).

There is literally not a more appropriate place to post this in a 2 hour online search quest to find such a place. So, to sum it up, Mozilla does not include a, "Contact" link on most of their public facing pages. Only a select few have them. Mozilla offers absolutely no way to provide feedback from what I couldn't find. Any page with the feedback box "Did this help" thumbs up and thumbs down literally results in nothing except the box disappearing when I click thumbs down. Mozilla's emails to their email list recipients have no second form of contact information on them beyond a mysterious unnamed physical address (which is illegal btw and lololol, I am disgusted about this for a company that is supposedly all about legal transparency online). Then, Mozilla's "Contact page" (https://www.mozilla.org/en-US/contact/) contains a completely broken map that shows literally nothing but appears to be intended to show geographical regions to contact. They link to a Facebook page without a contact option. There is an extremely limited support menu that looks like it was developed by a teenage web developer and which offers NO link to a Mozilla foundation support option. The dinky little "Get Help" link at the very bottom is the only thing that could even remotely be related to getting general Mozilla foundation help/offering feedback. Clicking on that routes to the help forum homepage which has zero options for Mozilla Foundation or Mozilla pages reporting broken features and etc. The Mozilla Github seems to only be tailored towards the various Mozilla coding projects but seems to be completely absent of actual Mozilla applications such as Firefox. Doing an extremely thorough Google search for the email address of Mozilla or any of its public facing representatives resulted me with absolutely zero results. Mozilla doesn't even openly provide a mailing address to the public on its website from what I could find (this is scary to think about in a scenario where I would need to mail legal documents to Mozilla). Mozilla has no publicly listed phone number anywhere on Google. I could not even find any leaked email addresses to anyone whatsoever within the Mozilla foundation, almost as if they actively scrub them from search results. This seeming lack of connection with Mozilla's actual users is quite concerning to me. Lol, if I were writing one of Mozilla's privacy review articles on Mozilla themselves, I would give a warning sign due to a designed communication-killing wall between them and their end users.

Please reroute this concern to the correct area. I know it is not posted in the right place but Mozilla literally left me with no option on a more appropriate place to leave it.

I tried to register at link text and when I entered my email addy it told me that email address is already in use. I tried my secondary email addy and was told same thing. I don't remember username and for that matter, don't remember a previous registration. So how can I contact admin at site or who do I contact to resolve issue or what do I so now?

I read that Firefox will using the Snap version by default on Ubuntu 21.10 and beyond. Will the non-Snap version still be available in lets say Ubuntu 22.04 and beyond? The reason I ask is because I use Firejail to sandbox Firefox and Firejail doesn't work with Snaps and yes I know that Snaps and Flatpacks both sandbox apps but I prefer Firejail because of the Private Home profile (nothing is saved in this profile settings, bookmarks, add-ons etc) its way more secure than the sandbox offered by a Snap.

I updated to the latest version of Zoom on Aug. 31 - as directed by my university. Immediately experienced issues using Zoom, and using MyLearningSpace aka Brightspace aka Desire2Learn.

Issue with Zoom: When I'm in a class (Zoom meeting), if I share screen, the Show Video panel option is now gone. Completely disappeared. When I stop screen sharing, the Video Panel comes back, and the option to hide or show it returns to the menu. Unfortunately, this is a nightmare for me - I can either show my students their slides, or I can see them to answer their hands up. I can't do both - which obviously I need to be able to do. So I basically can't run class on Firefox now. My uni IT has no idea what is causing this or how to fix it.

My uni IT keeps telling me, over and over, "Stop using Firefox. Use Chrome." I don't want to stop using Firefox, though. I've used it for decades and I believe in the product.

I asked over an a Zoom community forum, and several Firefox users replied that they are having the same problem. I can forward that thread, if it's helpful.

I am using the latest version of Firefox.

Thank you for any suggestions.

Firefox leaves full-screen mode when window manager remaps window to be in a frame and re-sizable.

In the window-manager that I use (KDE plasma), I can ask the window-manager to exit full-screen mode, without telling the window. This allows me to tell a window to be in full-screen mode, while in a framed window. I have attached a screen-shot of chrome showing a youtube video. Both youtube and the chrome are in full screen mode, however the window manager has re-sized it and added decorations (title-bar&frame), and is allowing me to resize, move, minimize, maximize, etc.

This works for every program that I have used (that has a full-screen mode). However it is not working for Firefox. It seems that Firefox is triggering off of the wrong event.

My guess: the window-manager sets NET_WM_STATE_FULLSCREEN to enter full-screen, and would normally clear this attribute to exit full screen. When we exit full-screen, but stay in full-screen mode, the attribute is not cleared. However Firefox is triggering off of something else such as a re-size event.

Use-case: What I am trying to do

1. Enter full screen mode: browser hiders tab-bar, and address bar, maybe web-page changes layout (e.g. you-tube resizes video player to fill window)
2. Tell Window-manager to leave full-screen-mode, but not inform browser (or other app). Browser is now still hiding tab-bar, address-bar, site is till showing video in whole-window, but window can be moved and re-sized.

This works for every other app that I have user. (Some apps don't have full-screen-mode, so this does not apply to them. But it works for all that do have it.)

Hello Team,

There are two things which have been missing out from Firefox for many years.

1. Allow the Add-ons for (only) Private mode - Extra Protection. There are many Add-ons which I am only comfortable running in Private mode. There has to 3 options in the settings to choose; enable add-ons in Standard Mode, Private Mode or in Both.

2. Useless History - Unnecessary Overhead on Disk and Memory. There are many websites for which I don't want them to have a History such as Google Search; Gmail; Outlook; Twitter; YouTube, etc by obviously running in Standard Window (Not Private).

Users should have the option to let the Firefox know to not save visited URLs history for specific websites. Or keep the history not-older than 30-days for selective websites.

Let's make Firefox more secure, efficient and faster!

Regards, Rashid

I'm using Firefox on Ubuntu 20.04.3, at a dual-monitor setup. My problem is that in a Google Meet or Rocket Chat call, I can't present only one of my screens. My options are or to share a specific window, not practical because most of the time I need more than 1 window, or "screen" but it always presents both of my screens. ( not practical at all) Is there any solution regarding this issue?

Changed my cell phone. Now with Bell Mobility - can not access accounts due to conflict with Firefox. Using version 92.0.1. I have never had a problem with Fire Fox, now they want me to load Chrome or Edge, which I will not use. Alternative suggested was also not acceptable "MyBell app" on phone. Currently using HP laptop with Windows. Any ideas??

I have managed to transform / rotate almost all of my various buttons, bookmark folder icons & site favicons and also other icons like in the appmenu and the locationbar/ac_popup pane various search favicons along the bottom of that panel. (see below code)

However I have been unable to achieve the same with the follow areas: - bookmark/history sidebar. - menubar History and Bookmarks drop down menus & submenus. - locationbar/ac_popup panel site favicons

/*************************/ /* ROTATE ICONS ON HOVER */ /*************************/

/*rotate icons on hover*/

1. nav-bar toolbarbutton:hover > .toolbarbutton-badge-stack,

checkbox:hover > .checkbox-check, menuitem:hover > hbox > .menu-iconic-icon, toolbarbutton:hover > image, button:hover > .button-box > .button-icon {

 transform: rotate(30deg) !important;
 -moz-transform: rotate(30deg) !important;

}

/*rotate icons on active (clicked)*/

1. nav-bar toolbarbutton:active > .toolbarbutton-badge-stack,

checkbox:active > .checkbox-check, menuitem:active > hbox > .menu-iconic-icon, toolbarbutton:active > .toolbarbutton-icon, button:active > .button-box > .button-icon {

 transform: rotate(75deg) !important;
 -moz-transform: rotate(75deg) !important;

}

/*if it doesn't have this then the icons get swapped to the other side on hover*/

1. nav-bar toolbarbutton > .toolbarbutton-badge-stack,

checkbox > .checkbox-check, menuitem > hbox > .menu-iconic-icon, toolbarbutton > .toolbarbutton-icon, button > .button-box > .button-icon {

 transform: rotate(0) !important;
 -moz-transform: rotate(0) !important;

}

I would like to block some sites (entire domains) from injecting JWPlayer iframes while I'm trying to read the site. (The Hill, https://thehill.com, is particularly annoying with this.) However, I need to see content that some other sites embed in JWPlayer, so I can't use the nuclear option of blocking the cdn for jwplayer in my hosts file.

Are there any settings or add-ons available that allow by-domain blocking of JWPlayer? (I don't care if it's a "whitelist" or "blacklist" approach, so long as I can manually determine which sites play and which don't.)

After installing 92 characters are constantly dropped in web pages, necessitating constant refreshing. Make screens unreadable. See screen shots of Yahoo mail and CNN. Win 10.

Why did Mozilla change the "Clear Recent History" dialogue window so that it NO LONGER has the "hotspot" that the cursor automatically goes to to make it quicker and easier to "Clear All History" after SETTING the choices to "Everything" and choose all of the options? The cursor USED TO be able to be set to go to the "OK" button automatically, now it does not. Why and why not? AND the dialogue window has been ENLARGED and SET in a CENTERED LOCATION onscreen. Why? Is it POSSIBLE to correct this oversight and allow for the cursor to go to the "OK" button automatically again? It seems that Windows 10 has presented additional challenges in maintaining a pleasant experience for MOST services/apps, and I hate that MS does that at every "update".

If there is NO way to correct/re-establish these functions to Firefox, Thank You for your time and efforts to keep Mozilla users/friends safe and happy, and stay safe and well,

When I start up firefox I usually select restore previous session to get back all my tabs, but sometimes I click on the wrong button and accidentally close out firefox. When I open firefox back up and try to restore the previous session, it restores to the session where I misclicked and only brings up the homepage. Is there a way to restore to the session before that with all my tabs, without having to go into browser history and bringing them up one by one manually?

Some of the answers to similar questions involve going to "%appdata%\mozilla\firefox\profiles\sessionstore-backups", but all of the files in that folder are either from several months ago or from after I messed up and lost my session.
