Hi, Please advise how to remove, disable, delete, block the new added "Your browser is being managed by your organization." to my Settings page. I'm home user .Also Please know that this is generating "FALSE FINGERPRINT CERTIFICATES" thank you

New computer, Win 11 and FF 120.0.1 all fresh installed and updated with latest versions. The double line spacing in bookmarks and all other menus is back. There was a fix for ver. 89 with the css file trick, but that DOES NOT WORK with this version. All other options I've run across don't work either. Why do the Mozilla software engineers think it's a good idea to break their flagship application every few years? Rhetorical question, I know.

Does anyone have a user fix that actually works with this FF 120.0.1 version? Something an experienced user can do that is not a programmer. analyst or engineer? I've been using FF since it first came out to challenge Microsoft's IE. Late '90s? I'd like to keep using it but this is too annoying to tolerate.

If anyone can help with step by step instructions, I would be eternally grateful.

Firefox on my mac has recently started displaying strange text in any windows where the browser itself chooses the font. I verified that the font settings are default, and the issue persists. Screenshots attached, any ideas?

Only my mac has this issue, my iPhone, as well as two Windows PCs all on the same account do not present with this.

The puzzle piece icon is not on the toolbar. Neither is it shown in the customize toolbar dialog. I have reset the toolbar to default, rebooted Windows 11 and removed & reinstalled Firefox 120.0.1 (64 bit). Those did not work. How can I restore the puzzle piece icon to the toolbar?

I had 2 windows open, closed one, lost all of my tabs. Restore didn't work. I tried to restore by renaming session-store-backups folder files. doesn't work. There is a file called upgrade.jsonlz4 from November, maybe that could be used to restore tabs somehow?

Open this url https://openfde.com/intro.mp4 and firefox shows "video can't be player because this file is corrupt".

Chrome is fine.

I am using Firefox 120.0.1, and I have difficulty to take screenshot.

I tried to press shortcut key and button in toolbar as shown in the attached image, but they didn't work.

Is there any good way to fix this problem without reinstall firefox app?

I set the browser to Open previous windows and tabs at restart, on General settings, but it always opens blanc, not saving any tab from the previous session.

How can I correct this issue, if it is one, please?

Hey,

I've been having an odd issue with Firefox where tabs where I attempt to access youtube.com will immediately crash. This issue first arose when I attempted to log in to Youtube, and had never occurred before. When I did that login, the tab crashed, and I have been unable to access the website since (100% crash rate).

Basic details: The website does not visually load at all. However, the URL bar icons for the website do briefly appear prior to tab crash. (Autoplay button, etc). The crash is never reported in about:crashes.

I've tried the following tests, unsuccessfully: - Logging out of all Google accounts separately - Disabling all extensions - Transferring all of my data to a new computer - Reinstalling Firefox - Rebooting Firefox in troubleshooting mode

This problem does not occur on my Windows machine but occurred on my previous intel-based Mac and now on my current Apple Silicon Mac.

The only success I have had is in creating an entirely new Firefox profile. However, I would prefer to fix the issue, as I assume that porting all my settings to the new profile would... also probably bring the bug along.

Thanks for reading & any advice is appreciated.

I have Firefox set to ask me where to download files that I want to download. It works for normal download links, but when I'm using my credit card company site's PDF viewer to look at a statement and I click on the download icon or link in the upper-left, it simply downloads the PDF (to my chosen "Save files to" folder in Settings). Is there a current way to change this behavior? Is this something that the website's code determines, overriding my Firefox setting?

When trying to click on links inside PDFs, the url is changed to undefined, producing an error message. For example, a Hostgator article is converted from https://hostgator.com/help/article/how-do-i-change-my-dns-or-name-servers to https://undefined/help/article/how-do-i-change-my-dns-or-name-servers

I have tried clearing the cache, troubleshooting, and get the same result in safe mode, and reverting back to Firefox default settings. And I still get the same result. I've attached an image of the error message.

I frequently use GroupMe on desktop from Firefox, on two separate computers (a self-built desktop, and a Dell Latitude laptop).

Starting sometime over a week ago, I have been unable to drag & drop or otherwise upload photos in my chats. The only method that works is pasting direct URLs of JPGs.

In all other circumstances, I get the uploaded image error attached to this post.

Two different GroupMe support agents have said that, since image upload is still working in Edge, that it's a Firefox problem.

Tried clearing cache, site cookies, reset the browser, ran in troubleshooting mode...same result every time.

This is not the "image file size too big" error. I used to routinely post captures from the Snipping Tool, and I can't anymore.

I'm not sure where else to go to troubleshoot this. It's very annoying. Any suggestions?

Hello,

After FireFox 80, the shortcut key of "Copy Link" and "Copy Email Address" was changed to L from A. This is really inconvenient for most right-hand users..

a> I posted a link 2 years ago below. But it is not working in the latest Firefox 120 under Windows 10. https://support.mozilla.org/en-US/questions/1333526

b> I believe a lot of users are looking for this answer like this one below. https://support.mozilla.org/bm/questions/1334749

c> Yes, thanks to this add-on which will add an extra link with shortcut key A, but it shows 2 duplicated links. https://addons.mozilla.org/en-US/firefox/addon/copy-link-address-a/

Anyone know how to change the L to A natively? I prefer the same way as a>, or post an add-on like c> but to change existing L to A, not add an extra link.

Thank you so much! Brian

Outlook displays the "To:" and "Add a subject" labels in black/grey text, but the rest of the "New Mail" window is white. There are no visible border lines between the "To" line and the "Subject" line. And no visible border between Subject and the email body.

The side-effect is an elderly person writes their entire email into the subject line field because it is not obvious where the email body starts.

I've seen this behavior on 2 different computers running the same (latest 120.0.1) Firefox. Odd thing is that I DO see borders when I run Outlook.com on my work laptop (same Firefox version). What config settings might control behavior like this?

I captured screenshots of the desired display of borders on my laptop. Tried .jpg, .png and .bmp. All of the files showed the borders between To, Subject and email body. But when those files are transferred to the PC I am on, the borders no longer display. Bizarre. I uploaded/download the files using Onedrive to ensure that the corporate email server was not touching the files. Even then the borders that exist in the files on the laptop do not display when those same files are viewed on my home PC.

Hello, I've got two profiles, 'Home' and 'Work'. I run two Firefox windows with these profiles. Now, I want to open a link from another application, like Slack or terminal, and want it to be opened in some predictable Firefox window. Now it depends, probably, on which Firefox window I opened last. So I want to be able to select in which window the links should be opened: I see it as marking a window as the default one. Note, that I don't want to set a default account, as there's no default account for me, I always choose which account to use when opening Firefox.

Thanks.

Foxnews.com causes Firefox 102.0.1 to freeze when scrolling pages with lots of images. Closing and restarting FF does not help. The freeze reoccurs. What does help for awhile is to delete the file places.sqlite. After that FF runs for a few hours until the problem happens again. Is there a setting or other fix for this issue?

AdBlockPlus and uBlock Origin are both installed, but are disabled on www.foxnews.com.

After running Import and Backup and selecting the date I want, the left column in the Library shows History, Downloads, Tags, and All Bookmarks. Under All Bookmarks, those folders have all the stuff I want in my Firefox browser. Currently my browser shows the folder names, but the folders are empty. How do I get the left column into my browser?

I had to totally rebuild my system from the bottom up. I had a copy of my old profile stored in the cloud, so I figured I was OK. When, I copied the files from the saved profile to my new profile, everything came over except my bookmarks. I copied the places.squlite and favicons.squlite files (which I understood to contain my bookmarks) separately and pasted them separately into the new profile, but to no avail. I used to keep a separate backup of my bookmarks, but when I learned that the bookmarks were kept in the profile, I stopped. How far up the creek have I gotten myself stuck, and is there a way to restore my bookmarks?
