Firefox Support Forum

Sometimes I get notifications from Firefox which send me to "usefulcontentsite.com" (don't click this, might be harmful!) and when I click them, uBlock Origin blocks them. So I'm pretty certain that is spam (or worse). However, I could never attribute this to any page or maybe some harmful extension I have installed. Also, I mostly block site's requests for notifications.

Here is the list of installed add-ons: - ClearURLs (recommended by Mozilla) - Firefox Multi-Account Containers (official extension) - KeePassXC-Browser - uBlock Origin (recommended by Mozilla) - User-Agent Switcher and Manager (recommended by Mozilla)

So imo nothing exotic here.

Does anyone here have a clue where those notifications might come from?

I use a VPN connection to access my workplace. This means that all my DNS queries MUST go through the company's VPN tunnel.

Firefox is deliberately blocking my work. The DNS over HTTPS "feature" does not work over this VPN connection.

In Firefox, there was previously the following setting: Preferences > General > Network Settings > Enable DNS over HTTPS

I REALLY NEED to have this setting restored right now.

I don't remember with which version of Firefox for Linux this issue started; but I cannot play multiple videos at once. If I open two tabs with video sources one of the videos will automatically pause if I start watching the second one.

I have tried disabling my add-ons but the issue persists and I don't think there should be any reason for any of them interfering with videos.

Currently running Firefox 120.0 (64-bit - Arch Linux)

Every time firefox has updated this year it prevents me from signing into my Navy federal credit union account. I get the following error message; Access Denied You don't have permission to access "http://signon.navyfederal.org/siteminderagent/forms/mfa.fcc" on this server.

I have had to turn off the ad blockers in the past and delete all the history including sign ins to get it to work again. This update I again went through all of that and also tried turning off every extension, turning off firefox tracking blocker and even reset the network setting to no proxy. Nothing works. Will I have to go back to using the google spyware browser just so I can do my banking? Or can this problem finally be fixed? If firefox worked with NFCU forten years prior without any difficulty I don't know why it cant be fixed.

I use firefox 115.3.1 on debian12 and chat with gpt on poe.com, firefox can't get the response dynamicly and it can only be loaded when the whole response finish, but it run properly whan I use chrome. Whan I press F12, I see many gets were red(ns-error-net-interrupt), how can I fix it?

I'm having the exact same problem as what was originally mentioned in this post from 4 years ago.

The "chosen solution" was to exit firefox through the hamburger menu, which I find to be absolutely ridiculous. You mean to tell me that even though I close EVERY OTHER APPLICATION either using the "X" close button or a custom keybinding that I've set for my own personal convenience, firefox requires me to exit through a menu every time in order to make it behave the way I've told it to? No. Absolutely not. If I tell firefox that I don't want it to save my last session, that means I DON'T WANT IT TO SAVE MY LAST SESSION. If I've deselected the "open previous windows and tabs" option in the settings, then under no circumstances should it be trying to open my previous windows and tabs.

I've tried the suggestion to change the value of browser.sessionstore.max_resumed_crashes from 1 to 0. The problem persists, I assume because firefox considers being closed using the close button to be a "crash", which is interesting.

I the other suggestion further down in the thread was to set browser.sessionstore.resume_from_crash from true to false, which will prevent firefox from recovering a session from a crash. This is hardly an appropriate solution. I want firefox to resume my last session if there is a legitimate (key word LEGITIMATE) crash, because my session was closed against my will due to something that went wrong. Being able to recover my last session in such a situation is nice. I do not, however, want firefox to resume my last session when I explicitly closed the last session myself, which would be the difference between a crash recovery and restoring a previous session. If no crash occurred, I don't need a crash recovery, and aside from a crash, I don't want my previous session to be restored.

Are there any solutions to this at all? Because this is one of the biggest reasons why I stopped using firefox. I want to come back to firefox because everything else that's worth using is either dog shit, or Chromium-based (i.e. also dog shit). However, I find this broken feature to be somewhat of a security issue. If a bad actor somehow gains access to my system, I don't want him to be able to open firefox and have access to my last browser session because I closed firefox using a keyboard shortcut instead of closing it through a goddamned menu.

I was using Lightspeed today, and the website pops up a confirmation dialog box (probably through JavaScript) so that you can confirm that you want to do a specific action. I got annoyed with the dialog and clicked the included "Don't allow this website to show prompts anymore" box when I hit OK. But now it won't perform any action that requires you to hit the OK in the prompt, so I need to make the dialogs come back so I can do my job. I can't find any setting anywhere in the browser that I have actually disabled or changed by hitting the box in that prompt.

Is it possible to perform partial bookmarks sync?

Let's say, bookmarks from machine A that are synced to the server completely would be then synced from the server to a bookmarks subfolder on machine B, is it possible? The rest of the bookmarks on machine B would need not to sync to the server in such case.

Alternatively, both machines sync to the server but the user would need to specify which bookmark sections (folders) need to be synced and which not, thus avoiding duplication and maintaining consistency.

Sometimes a bookmark folder on my toolbar randomly won't open. I can go to Manage Bookmarks and see the bookmarks there, but the folder on the toolbar won't open when I click on it. I haven't changed anything on the folder. Sometimes deleting a bookmark in the folder and restarting Firefox fixes the folder, sometimes it doesn't.

I haven't noticed any errors.

I'm using Firefox 118.0.2 (64-bit) on Ubuntu.

Is there a way to use the default xfce windows instead of firefox`s own? I mean I have my own setting in the xfce window manager that are not applyed to firefox. fo example: I unchecked Raise windows when clicking inside application window, that is not applyed to firefox, I also have a context menu when right clicking on other windows title bars that I can customize, In firefox I have something total else.

Web page loads incorrectly. so far this is the only page, the same time on other computer all is ok. cookies and cache is clean. Linux Mint 21.2 Cinnamon 5.15.0-83-generic Firefox 117.0 (64 bitu)

The videos on YouTube work, but when I go to other pages I get this message, I already tried removing all the add-ons, the hardware acceleration, even doing a 0 installation and it still gives me the problem, and also in others devices with fedora, I get the same error.

Dear Well Loved, Firefox community.

I wanted to ask if theirs a trick to, or if not, ask for a how to ask mozilla to create a new functionality for storing you Default Session Setup.

Whats the idea, is very simple. This surges, for my needs of how I use the tool.

Somewhere, 70%-90% of my work week hours are spent on a browser, specific on the very best and my first love, Firefox (well si was not may first, but it the closest to Netscape, my true love). For organization reasons, I always open my tabs on the same order and pin the first 4 to 5 tabs, there are my top 4 to 5 tools, example: my email, my calendar, messaging (whatsapp or slack), , my comapy tab (erp, crm, wms, etc).

So it will be nice, that at any divice I'm login, every time I open my Firefox this pin tabs always open first, so that my working setup is open wright away.

the secondary emailaddress in the account details screen is none I attempt to enter my secondary emailaddress der********le@gmail.com I cannot enter that address becuase I get the errormessage thet that address is already known let me know how this can be addressed D. Giroulle

OS: Ubuntu 23.10 Firefox version: 119.0 Mozilla Firefox Snap for Ubuntu

I have DNS over HTTPS enabled and set to Default Protection in Firefox.

According to the following article (https://support.mozilla.org/en-US/kb/dns-over-https?as=u&utm_source=inproduct#w_why-would-a-network-tell-firefox-not-to-use-secure-dns) DNS over HTTPS should automatically switch to "Not Active" when connected to a VPN.

I am using the NordVPN CLI for linux and have found that when I connect to the VPN, Firefox DNS over HTTPS stays active and does not switch to "Not Active" like it is supposed to.

Does anyone know why this might be happening?

It seems that this problem is common in firefox community. So first of all I basically tried all default troubleshooting steps such as dealing with cookies (turning off, tuning on, exceptions), cleaning data, cleaning cache, security settings, etc etc, even though I am on freshly installed firefox.

So lets see now, problem is with https://vk.com/ website. It works until processing my login info. After I enter necessary credentials, it reloads and just produces infamous error. Network monitor displays loop of login.vk.com domain migrating cookies to login.vk.ru which restores them and then finally trying to open actual account php page starts the loop anew. Well until NS_ERROR_REDIRECT_LOOP stops this shamelessness. Resetting all browser data back, just enables me to enter my credentials again and the same process starts again. I can access this website from the same network from different browsers from different devices and operating systems.

Currently I encounter this problem on recently installed Arch linux, with basically dwm and firefox, and since I had very rough time with how unpredictable this system were so far, I don't know how much it is browser issue, so I think I should mention it.

Thank you in advance.

Some of my websites load very slowly. So slow that I can use Chrome, login to that site, complete my business, log off, and Firefox is still loading. I don't load extras into Firefox and I don't believe I have anything extra loaded. Some of the websites I have problems with on a regular basis are: Yahoo.com, loading articles, and Synchrony.com for credit cards, such as Amazon, JC Penney and others. Occasionally, close to rarely, they will load immediately, but the majority of the time it takes minutes. Thank you.

This isn't a constant issue for me, but occasionally the browser will suddenly break such that when I switch tabs, nothing actually updates until I do something like restore/maximise the window. I can still interact with the page itself, but whether using the mouse or keyboard shortcuts, changing, opening, or closing tabs, or even typing in the navigation bar, won't do anything until I resize the window again. I haven't been able to figure out any pattern to when this state triggers, but after it does, it doesn't clear up without closing and reopening the browser. I have recorded a video showing this behavior but I am unable to upload it here, and still images would not properly convey the issue.

I'm using my imac to report problem...My laptop froze while using proton vpn to watch sportsurge. force quit unplugged and could not connect with firefox when i turned computer back on
