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?

Everytime I go to play games on my laptop I close Firefox for the extra resources and when I'm done I open it right back up, I have done this for YEARS but this time it didn't restore my session. I thought it would be as easy as the last time where I'd go click the Restore Session button but it isn't there so I spend two hours looking for solutions and found nothing. I don't know how this happened nor do I understand how this could happen in the first place, my Firefox hasn't crashed in months and I had already closed and re-opened it several time today.

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?

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.

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.

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 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?

Every time I am trying to search, google is always pinned on my search bar, and I want to get rid of it. How can I remove google? (On the image I marked the issue with a red circle)

Chrome is fine.

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

Running Firefox 120.0.1 on Windows 10. I also run Vivaldi and test with Chrome. I installed Google Analytics Opt-Out add-ons on FF, Vivaldi, and Chrome. When I go to any site with links to X (Twitter), and click on the link, instead of that link appearing the last X link I went to appears. If I click again I get to the correct link.

When I disable the Google Analytics Opt-Out add-on all works fine. This doesn't happen with either of the Chromium browsers, so I'm thinking there's something happening in Firefox by avoiding Google analytics that isn't in the Chromium browsers. In addition, this behavior began within the past couple of weeks of recent FF updates.

I installed several different Google Analytics add-ons and the same thing happened in FF, but not in the Chromium browsers.

Any ideas? I know I can disable the analytics crushers but I really don't want Google hijacking my browsing.

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?

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.

Steps I've taken to try to fix the issue. 1. I've cleared all cookies/cache/history 2. I verified that network.dns.disablePrefetch is set to True 3. I started Firefox in safe mode 4. I've made sure Firefox is up to date 5. I've tried modifying security.tls.enable_0rtt_data to both True and False and reset firefox after each attempt. 6. I am able to get to google using any other browser but Firefox is having issues. 7. I am able to ping google and google dns from cmd. 8. I've tried clearing local dns cache and trying again but no luck. 9. I've uninstalled Firefox and reinstalled, still no luck. I cannot use google.com or use services like Crunchyroll that use google to login.

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.

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?
