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.

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Popups for Smithsonian magazine keep appearing, sometimes 2 at a time, despite having popups blocked. I need them to stop. They are annoying and cover up content of web pages.

Firefox is deleting my website exception list whether I have "Delete cookies and site data when Firefox is closed." checked or not. It is the same with the exceptions list for logins.

I'm using a new PC with Windows 11 and find that I, inadvertently close Firefox with 16-20 open tabs. Most of the time when I reopen FF, the tabs are still there, as expected. Sometimes, the browser opens with just a new home page and the pinned and other tabs have closed. I can sometimes see the 16ish tabs in history and reopen them. More recently, I find that they are not in history as a number of tabs so I have to set them up again. This rarely happened on my old PC and if it did I would have bookmarked a group of open tabs that I used regularly.

The failsafe FF General setting is as follows: Startup, Open previous windows and tabs.

I don't know how I can stop losing my open Tabs but if I was able to bookmark all the open tabs to be used in case of a problem I would feel more secure.

How do I bookmark ALL or several my open tabs?

My ISP had provided the IPv6 service, edge/chrome/vivaldi are all IPv6 first and working well. Only firefox insists use IPv4, although it could also pass the IPv6 test on https://test-ipv6.com, and the internal test on https://detectportal.firefox.com/success.txt?ipv6 It leads to some webpage extremely slow, even could not be accessed.

I've tried privacy mode, but the problem is still there. IPv6 in about:config is enabled, all related options are default. Is this a bug, or if there is any way could fix it by some special settings?

Waiting for your help, thanks.

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?

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.

I have noticed a bug with how the Firefox icon appears when launched in the Windows 11 taskbar when the never group option is enabled. When Firefox is launched and is the only application open in the taskbar, there is no label present next to the icon like other programs have when launched. There is the little line underneath the icon though indicating it is launched but that is it. As soon as I open another application though, the label will also appear for Firefox. This is only a minor annoyance but is definitely as bug at least for me and should be pretty easy to fix. I will attach screenshots of the behavior. In the first screenshot, you can see that Firefox is open but has no Text label like it is supposed to. The second screenshot is as soon as I open a second application.

I am on Windows 11 Home 23H2 Build 22631.2792 Windows Feature Experience Pack 1000.22681.1000.0 Firefox Version: 120.0.1

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.

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.

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?

As of recently, every time I try to watch someone on Twitch, where the video feed would normally be is the streamer's offline banner image. Chat is working fine, and is active despite the stream not being displayed on my end. If I check the Twitch mobile app the stream displays as normal, so I know they are currently streaming. I tried disabling all of my add-ons and restarting the browser to no avail. I am a noob, so please be patient with me. I have attached images of an example, but this happens with any live channel, not just ones I am following (I do not have any active subscriptions as far as I know).

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?

tell me how to undo "troubleshoot mode", read the "help" article, do not understand.

tell me how to undo the "More from Mozilla" in about:preferences. I have NO idea.

I try, but I am usually confused by these help articles.

Hi all.

I use Firefox 120.0.1 with the setting "Delete cookies and site data when Firefox is closed" to clear said data when closing Firefox. I have also set an exception for a few websites, so they should save cookies and data. However, this does not work as intended. After closing and reopening Firefox, both cookies and data are gone from these websites. I have looked for a solution in older forum entries, and it was recommended to adjust the history settings. It seems that checking the box at "Delete cookies and site data when Firefox is closed" automatically sets the history settings to what can be seen in the attached screenshot. Altering these automatic settings unchecks the box above. Is this issue related to the website or is there a way to solve it?

For the last couple of weeks, whenever I access the finance.yahoo.com/ website, my computer slows to a crawl. I run Activity Monitor to show me FF memory usage has surged to 6.5 GB! I cannot just 'quit' FF, have to force quit to regain the memory. No problems with any other website. I am running Mac OS 12.7, 8GB RAM, FF 102.0.1

Any help/suggestions appreciated.

Is there a setting or add-on for firefox (Windows) that will block tracking pixels? My email client hi-lites when present and as I understand they are incorporated within images so I dont down load attached images to reduce them. On their pro version they allow blocking of these pixels. Unlike cookies there doesn't seem to be an option on reception to opt out. I'm not fully clear what harm they do or whether they are session use only and delete on power off. I would rather not recieve them atall. Companies when challenged smokescreen and refer to cookies rather than pixels or bang on about their companys integrity.

Thanks for your help

I am currently encountering an issue where firefox is giving me the PR_CONNECT_RESET_ERROR despite for no immediately apparent reason. I cannot access any website in Firefox.

Steps taken:

- I've deleted cache/cookies. - Disabled all firewalls and anti-virus software. - Removed all plugins / extensions. - Did a clean install of firefox (while keeping my profile). - Restarted my modem/router.

I have no proxy/vpn, so these are not issues.

Please help me!

I have a new PC running Kubuntu 22.04, with Mozilla Firefox 120.0.1 (64 bit) installed. Standard, the system window title bar was hidden. But I wanted access to the "Move to desktop" menu and wanted the title in the title bar. So, in "Customize toolbar" I checked "Title bar". The title bar reappeared, but a complete border along the Firefox window became inaccessible, and when clicking in that zone, it effectively clicked in the window behind. In particular, the complete menu bar is inaccessible, as well as the scroll bar on the left and in the bookmarks sidebar the fold/unfold. And Mozilla Thunderbird 115.5.0 has the same annoying behaviour. Even when hovering over some menus in the Mozilla window, you can sometimes see reactions from the window under the Mozilla window. On older Kubuntu computers (up to 18.04) with older versions of Firefox (up to 113.0.2) and Thunderbird (up to 102.11.0) I do not have that problem. How can I get at the same time access to both the system title bar and the menu bar ?
