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.

Firefox use to keep me logged into Asana. But after deleting my browser cache a while back, it no longer does. Even though it still keeps me logged in to other sites I go to.

I have already tried to get help with this on Asana's help forum and a computer help group on FB. As well as from researching on google. I have tried everything they told me to do and it still isn't keeping me logged into Asana. I am completely baffled as to what it stopped keeping logged in. But I know it had to do with deleting my cache because it did it right after that when I tried to log back into Asana. It never kept me logged in again.

When I deleted my browser cache I made sure to not check the one that said it would log me out of website if I check it. I didn't delete that, I just deleted the other stuff that was in the gb range. So I don't know why every time I delete my cache it still logs me out of all website anyway even though I uncheck that.

Yesterday I reset firefox back to its default settings, but that didn't help either.

Any ideas what else I could try before I uninstall firefox and reinstall it. I have backed up my bookmarks, but the last time I had to import my bookmarks when I got a new computer it did not import them correctly and it made a mess out of my bookmarks and didn't even save my browser toolbar stuff. So reinstalling Firefox is my last option.

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 just tried to connect to YouTube & get "You're offline. Check your connection." I assume this is due to a DoH connection issue. I can connect in Chrome. My Firefox Mozilla Connection Settings are "Use system proxy settings", though I have set this to "No proxy" in an attempt to fix this - didn't help.

Under Privacy & Security: "Enable HTTPS-Only Mode in all windows", "Enable secure DNS using: Increased Protection" - tried "Default Protection" - no help. Using Cloudflare default.

It has been a few months since I tried YouTube - not sure what's up. It works in Firefox on my phone..

Offidocs has hijacked my Firefox browser making it impossible to read PDF files. I never added it and it does not appear in my extensions list. I've marked "always ask" in the preferences for opening PDF files but to no avail. My antivirus and Malware bytes scans are negative. How can I get rid of this?

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.

on some websites it says -1 tells Firefox to automatically determine the size of the cache based on your physical disk and setting it to 0 would effectively disable any disk cache entrys.

so are this informations true and if not, how do i still let firefox automatically determine the size of the cache based on my physical disk?

Hi all!

I am using Firefox Multi-Account containers with Firefox 120.0.1 (64-bit) and the New Outlook desktop client with Windows 10(*). I have more than one Office 365/Outlook account, so I use different containers for each account.

Whenever I click on any link in New Outlook, it opens in one of my Firefox containers rather than in a default No Container tab.

Unfortunately, it opens in a container where I am logged into a different Office365 account than the one I use for the desktop client. This means any Office or organisation-specific links fail to work unless I copy and paste the link across.

Is there some way to force Outlook to open these tabs as No Container?

Thanks, penguinoid

(*) I'm using a university owned/managed computer and they've disabled the option to update to Windows 11

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

Hello,

i just can't download anything on Firefox anymore for no reasons.

I already tried to modify the download folder, to reinstall, to repair firefox with no success.

Dear FF/Mozilla:

I've experienced a number of issues where I'm unable to do banking transactions using the FF browser. In one case, Wells Fargo bill pay does not work (but works fine with MS Edge); in another case, an international money link payment to a vendor in the UK would not go through using Firefox (but did first time with MS Edge). In yet another case, Firefox won't load webpage photos for items for sale on the site www.telescope.com - the page loads with descriptions but photos would not load (I just tried it and, nada). This remains the case even after my VPN is disconnected.

I've used FF for several years now without too much trouble but with this ongoing non-functionality of FF, I'm tempted to migrate to MS Edge or a browser that is supported more widely.

Any help or advice? Thanks, Blaine

I have a little annoying problem with google and firefox that appeared (don't know if it is firefox bug or a google new policy) In the past when i did a research on google with firefox, the "sharing my location" popup only appeared when i did a location related request (weather, shop/restaurant, roadmap, local news, etc) or only once for few days, but now (like few weeks or months) i have this annoying popup appear basically everytime, even for random search like math formula or fictional stuff (does pikachu or naruto jutsu really need my location?), and even when i type the same research twice, firefox ask for location again, like if it has a golden fish memory of few seconds. How to stop this popup appear when it is not needed without having it permanently enabled or disabled for google site.

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.

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).

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?
