Hi Team,

After updating to Firefox version 96.0, we are unable to login to our application, after pressing login button our login page is getting refreshed. From warnings it looks like a Cookies issue. As 96 version has SameSite:Lax as default but we are setting SameSite:None; secure; but it is not working.

Kindly help us.

Thanks & Regards

I have been unable to figure out how I've managed to make my addons no work properly.

I've tried running them in debug mode, but I'm not particularly adept in debugging addons.

I've reset Firefox back to default a few times, addons seem okay, and then as soon as my Firefox account syncs and installs my installed addons they go back to wonky.

I can't seem to attach images RN, Firefox (Nightly) crashes every time I click on the button.

The behavior can be described as the addons when clicked have a blank page as their contents, and some addons (Like Dark Reader) just have like a sliver of a drop down with no contents.

If you'd like me to grab some debug data from wherever just let me know.

I moved my Firefox installation to a new machine. After creating a new profile and moving all my old files Firefox has opened with all of my old info and is operating properly.

But when I tried to change the location of the cache file to the correct drive on my new machine the about:config file does not save the new entry. When Firefox is closed and re-opened the new entry has been reset to the old location.

I've tried deleting the browser.cache.disk.parent_directory entry in about:config but when the program is re-opened the entry returns with the old directory shown.

Any advise would be appreciated.

A while ago I made a Firefox account with my Yahoo email address as the primary email, and my Outlook email address as the secondary email. Eventually I realized that I didn't need my Yahoo email account anymore, so I deleted it, forgetting that it was being used as the primary email for my Firefox account. Now I can't remove my Outlook email from my Firefox account without verifying my Yahoo email account, and I can't even delete the Firefox account since it was made under the Yahoo email account as a primary email address.

Now I can't use my Outlook email address to create a new Firefox account either.

why is FireFox 95 opening multiple windows on startup with Windows 10, Roboform, & Norton 360? FireFox is set to open a new tab, not new windows, so I do not know why it is doing this? I see lots of people asking this question, but there is no guidance online. What is up? This is causing FireFox to use way too much resources, and slows the computer.

Hi all,

Since I switched to Win 10 Firefox constantly crash on my computer.

• Tried fresh install no change
• Tried repair no change
• Switched off extension and then on (one by one) no change
• Deleted cache - History - etc .. :( it worked for only a few days since I did a full scan with Microsoft Defender.
• Since this last crash (as I could not launch Firefox anymore I used shift + click on Mozilla shortcut)I decided to switch off the graphic card acceleration and all the other option in this menu and it seems to help

Could you tell me how to send you the crash report ( I do have 8-10 of them already sent to Mozilla)

How can I change my primary email address? I'm not computer smart to find your secret language to do that. Please change my primary email address to: [email edited from public] @gmail.com Cable one has pulled the plug and disconnected my previous [email edited from public] @cableone.net address. No one can send any emails to that address anymore as nothing is there.

I hope you can please help me. Jan Kautz

Hi Mozilla Community,

As of a couple of days ago, I've had trouble with my Firefox Extensions. The most apparent one being ads appearing on the sites I browse (I have the Adblock extension installed and active). The extension that reveals the "dislike" ratio on Youtube only works if I disable and then enable the extension, for each video I watch. My entire extensions toolbar seems faulty as well.

I've attached images to illustrate: - Rakuten just appears as a blank box upon clicking it - Video downloader extensions just appear as a white line (doesn't open at all) - Bitwarden (password manager) says "not available in private mode", even though I'm not using a private window

Any help would be greatly appreciated. Thanks, Matt

For the past two weeks, I've noticed that embedded maps make my browser immediately crash. I initially thought it was a Firefox problem, but I have been having a similar issue with Safari. This does NOT happen on my iPhone using the same two browsers. This also does not seem to effect Google Maps or embedded Google Maps, but embedded maps from other services. Anyway, I'm posting here because Firefox conveniently provides crash data, I'm not sure what else the cause could be and I'm hoping someone can help.

Two websites this has been consistently happening with are The Empire State Trail bike path (https://empiretrail.ny.gov/) and a NYC vaccine finder website (https://vaccinefinder.nyc.gov/). Firefox immediately crashes, though with the EST website it seems to be tied to the pathway of the trail being drawn (crashing after I've zoomed in a few times and the path has to regenerate). Safari doesn't totally crash, but forces a site reload and after it fails a second time says it can't display the site.

Any ideas what the issue could be? I'm on the latest version of Catalina (10.15.7), Firefox and Safari and seem to have all security updates for all.

Here's a link to the latest crash data: https://crash-stats.mozilla.org/report/index/1389c870-51cf-4790-b0a0-fd01f0211202

Hope someone can help.

When I use full screen for some websites, it darkens after about 2 - 5 seconds and my cursor also becomes harder to move. This only started to happen recently.

It is not my computer settings, I've tested this in Safari and it works normally. This makes videos unwatchable. It is like a dark screen suddenly appears over the video and only comes off if i move the cursor. It happens with netflix and prime but not youtube, udemy.

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

Hi,

I'm having a really strange problem.

I'm using Firefox on WIN 11 with my new LG laptop.

When I access a website's drop-down menu, it does not offer me options that I can make a selection.

I know that it's missing the 2 options - because when I try it on other PCs - it works fine. So the behaviour is different (and works) on other computers.

And the stranger thing is; it also does not offer the options when I tried it with Chrome and Edge.

I tried clearing the history and cache - and it still gives the same behaviour.

I called the Tech Support of the website - and they said it's clearly a problem with my specific PC. I would tend to agree with them - because I can access their site without any issues on other PCs.

I can't figure out what's in common amongst the 3 browsers I tried on this LG laptop. The only thing I found in common is this laptop!

Any ideas - any thing I can try next? Really driving me nuts...  :)

Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

1. I've performed a completely clean uninstall of Firefox and then reinstall
2. Cleared all browser history/cache
3. Removed all extensions
4. Disabled IPv6, HTTPS Over DNS, No Proxy
5. Ran through Firefox's troubleshooting
6. Used Firefox Troubleshooting Mode in the Browser
7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.

• Windows 11 21H2 2200.348
• Network driver is the latest Win11 edition
• Firefox 95

This is going to be long sorry. A lot has transpired

My son was using 78.15esr. I upgraded it to 91.3esr. After the upgrade the browser worked; tabs loaded, surfing was fine, could go into settings and about:config was fine.

He went to watch something on Netflix. Netflix complained his browser was not supported and he needed to upgrade to the latest version - which at the time was 91.3esr.

In frustration he installed Chrome. When he tried to run it he was told software restrictions were in place. I had not set any restrictions, and I checked secpol.msc and there were definitely no path rules defined. If restrictions can be set in group policy I had not set them because I am unaware of them.

So he installed Microsoft Edge, which installed VC runtime for 2013 and 2015-2019 for both x64 and x86.

At that point Firefox no longer loads tabs at all. About:<anything> doesn't work. Settings doesn't work. You can't go to safe mode (more on that later), and when closing the browser two processes remain taking about 60 seconds to end.

I did have the group policy templates for Firefox installed. When I upgraded to FF 91 I installed the latest templates.

A couple of times when I started FF it complained about vcruntime140 was missing. But just running FF again worked without doing anything else.

So I reverted to 78.15; I uninstalled v91.3esr. I deleted his profiles.ini and profiles folder and then copied them back from a back up. I removed any registry settings, and copied back the v78 ADML files. I then installed v78.15esr with internet disconnected. Did not run FF after install. Went into group policy editor and turned off telemetry and auto updates then re-enabled internet

Run FF and same issue. tabs not loading. Pages not loading. I can click on a menu and I can type into navbar and search bar but there is no response. I checked internet was working.

I deleted the %LOCALAPPDATA% cache folders. I flushed the DNS cache. None of this worked.

So I uninstalled FF again, deleted the profile folders and ini. Disconnected from Internet. Deleted any registry settings, and removed the group policy templates. Then installed 78.15 from scratch and let it create a new profile.

Same darn problem. It seems to me that installing chrome and/or edge has done something nasty, but I have no idea what. I say that because before he did that he could surf the web, but Netflix just said his browser ver was outdated.

I tried contacting netflix on chat but they were worse than useless.

So I uninstalled again and removed everything. Connected the internet and installed FF again and let it update automatically. Same problem.

I've left him with edge but I need to fix FF.

I even uninstalled the VCLibs, Chrome and Edge. These did not fix the problem.

I tried safe mode but when firefox restarts there are two processes that take 60+ seconds to end so FF sits there saying "restarting...". When those processes finally end Firefox does not restart.

Checked for viruses; nothing found. Rebooted PC several times.

So at this point in time; FF will run but will not load the 3 tabs; Facebook, Netflix and youtube. They stay blank. Settings is not accessable, nor is addon's or logins and passwords. Typing anything on the search bar does nothing Typing anything in the address bar does noting Trying about:config or about:profile or any other about's does nothing. When closing FF two processes take 60+ seconds to end.

If I go back to him and tell him I need to reinstall Windows he will go absolutely nuts.

What also worries me is that Netflix said that the most recent esr browser version was not supported and that he should update to a later version.

And what is even more troubling is I updated his girlfriends PC at the same time and hers works perfectly. This scares the hell out of me because I then expect responses like "Your sons problem is not a firefox problem".

Today, my daughter received a notification that the Dragon Professional Web Extension has been disabled (see attached image). This was done because the extension supposedly executes remote code and collects user data.

My daughter, a mathematics professor, has very limited use of her hands. She is dependent upon Dragon to do her job. This is not something she just likes - she has a disability and she NEEDS it. Disabling this extension will make her job significantly more difficult, and there are capabilities that the extension provides that she may not be able to duplicate with workarounds.

PLEASE, make the extension useable again. This is an accessibility issue for disabled people - it's not just a fun addition to the browser. If necessary, add some sort of acknowledgement checkbox so that she can acknowledge that she is taking some risks in using it.

One other thing. Disabling this extension with no advance warning was a disservice to all disabled people who depend on it. Had this occurred in the middle of a semester, the effect could have been catastrophic. As it is, she may need to spend the rest of the summer trying to figure out how to do her job without it. You have really, really done an extreme disservice here.

firefox not opening since 2022-01 Cumulative Update for Windows 11 for x64-based Systems (KB5008353). I reloaded Firefox. Google Chrome and Microsoft edge work OK. Task manager shows running but stats never change 0% CPU/0.2MB Memory

I usually have Firefox open for 8 hours a day (open Firefox in the morning and close it in the afternoon). About once a week I'll notice that at some point during the day Firefox will just stop loading new websites. Existing sites will continue to function, and requests to those existing domains work. But new sites, that I didn't already have open, won't load at all; the tab will just sit there, thinking indefinitely (no errors).

When it does this I will try microsoft.com or google.com to check and make sure it isn't just the site, but those won't load either. I'll try it with a Private Window as well to the same effect (private window has no extensions enabled). Chrome/Edge still work fine during this. In order to get Firefox working again, I have to close Firefox and then usually force quit the process instances (or wait a long time for it to reopen on its own). Once reopened everything is back to normal and all sites load as normal.

I think this happens when Firefox loads a new update in the background. I've noticed on more than one occasion this behavior has coincided with a new Firefox version. In fact it just did it again (prompting this post) and when I got Firefox back open again it had a new update tab displayed. So I'm fairly sure it is the background updates causing this.

This behavior has been happening for a very long time. At least 6 months. Across many Firefox updates.

I have a separate Firefox profile that I load using a separate shortcut (with the -P property). When this behavior happens it often impacts both instances of Firefox. Not sure if this bug is related to having multiple profiles or not.

Windows 10 64-bit

Hello team,

I'm not sure what happened, but I was not able to open Firefox after restarting my PC. I currently run Windows 11 on a fully upgraded rig.

Up until today, I have been trouble free. Error 1: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I tried several options - and have been googling/trying several steps for a couple of hours (after each step, I restarted the PC):

1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Attempted to use Command Lines to open Firefox https://wiki.mozilla.org/Firefox/CommandLineOptions 3. Opened Profile Manager and attempted to create a new profile - when I did this the new profile would not display in the Profile Manager, but it would display in the Profiles folder under Appdata [I tried this multiple times] 4. Deleted the profiles.ini file

After deleting the .ini file Error 2: "Your Firefox profile cannot be loaded. It may be missing or inaccessible." 1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Opened Profile Manager and attempted to create a new profile. After following the Profile Wizard, another error pops up: "An unexpected error has prevented your changes from being saved."

I am completely stumped. I hope you can help, Sean

Firefox will start once (maybe) and then it makes no difference where I click from (tray, programs, desktop shortcut) Firefox refuses to boot up. I've tried re-installing multiple times. If I reboot, it will start. Also sometimes I will get a New tab but the page/URL never comes up. Firefox just hangs. I'm running Windows 11.
