Firefox Support Forum

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...  :)

I use Kaltura to record lectures and post them to my course at the U of Utah on Canvas. This semester, Firefox will not allow me to open "my media" where the Kaltura recordings are posted on Canvas. I get the following message: It seems your browser is blocking 3rd party session cookies which are required for the Kaltura application. To resolve this issue, please update your settings to allow 3rd party cookies.

I copied the Kaltura web address 670542.kaf.kaltura.com that I can see in Chrome and pasted it into a Chrome browser and it goes to my recordings in Canvas when I use Chrome. The same site doesn't work in Firefox. How do I unblock Kaltura third party sessions? Thank you.

A short while ago, Firefox was automatically updated to 99.0.1 on my iMac running Monterey 12.3.1. Suddenly, for no apparent reason, the search engine is stuck on Amazon with no other search engine options available. I normally use Google.

Even if I go into the Firefox settings to the "Search" panel, it is showing ONLY Amazon as the available option in the pull-down menu under "Default Search Engine". In the "Search Bar" section, I have it set to "Add search bar in tool bar". But even if I set it to "Use the address bar for search and navigation", and then switch it back to "Add search bar in tool bar", Amazon still remains the only available search engine.

As a last step, I installed the "Google Search" add-on by 3Indian to see if I could get back my Google search engine, but Google still doesn't show up as an option anywhere, and I am still stuck with just Amazon.

Is this a bug in the latest Firefox build? Did the developers forget to enable something when they did this build perhaps?

I have had this issue before and uninstalling and reinstalling has fixed it in the past. Today when I opened firefox it prompted me to update , which I did without thinking. Subsequently, it stopped working. I have tried: restarting my PC, running in troubleshooting mode( it wouldn't even open when I tried this), uninstalling and reinstalling using the internet installer, uninstalling and reinstalling using the offline installer ( tried on multiple hard drives, so I don't think hardware failure is the issue), installing an older version of fire fox, and installing the 32 bit version instead of the 64 bit version. The attached images show what displays upon trying to launch firefox. nothing loads, not typing an address into the search bar, not clicking on a bookmark, the only UI element that will display is the 3 horizontal line setting menu.

Hi, The program SEEMS to start but Firefox does not load one singel page. I get no errormessage but firefox does not even try to open pages.

Also, if I try to go into "settings" nothing happens (no errormessage, but settings does not open).

I have tried to uninstall and reinstall Firefox. Does not help.

If I try some other bowser everything works fine. The problem started after I did a total uninstallation of Office365 (does not need to be depending on it but it could be a connection).

Have searched the web without finding a solution and now I ask for help here, I really do want to keep using Firefox but currently it is impossible.

I'm running 96.0.3 on a fully patched Win 10 Pro system - both O/S and programs. When Firefox is running I'm getting these pop-up error messages randomly with changing content. They stay on screen for some seconds and then go away. Message states it's from (via) 5.back2yard.biz. I put that in my hosts file and I'm still getting them. My network is a cable modem hooked to Xfinity and then cable connected to another fully newer patched router. All addresses are 10. range. I ran both a Malwarebytes scan and a Windows Security scan - both are clean.

I'm unable to upload a small image after a hour so I'll give up on that right now.

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.

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

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.

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

google.com and google related websites doesn't load at all. For example, gmail slowly loads, but loading icon never disappears, loading icon is always shown and then often it shows 'reconnecting' message. This works OK in Chrome.

Steps to reproduce: 1. Open Firefox without VPN - all loads well. 2. Enable VPN - stops loading. If I then disable VPN - it starts loading again.

If I restart Firefox it starts working OK, but after a while stops working again.

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

Walmart website no longer works properly with latest Firefox 96.0.2 64-bit. It works properly with Chrome and other browsers. You can log onto the site and search for products but when you try to add a product to the cart nothing happens. You also can't actually go to the cart. Last time I used Walmart was a few weeks ago and everything worked fine!

Since upgrading to Firefox 99.0.1 when I bookmark a web page into a specific folder, the URL does not appear when I open that folder. A restart of Firefox does not fix the issue.

But if I try to Bookmark the same page again, I am asked to edit it. So it must be in the folder but it is not visible! Help!

I have searched for this problem, and only come across outdated information about Youtube's intentional changes to slowdown Edge and Firefox in 2019. This is not that.

When I load a new youtube video, the video will buffer as normal, and then buffering stops. Then there is a delay of about 10 seconds. You can see from my screenshot that the buffer is filled just fine, and playback begins about 10 seconds later. This also happens if I skip ahead/back or to any position in the video. This firefox install is on a new install of Windows 11, with a new xps 13. The previous xps 13 with windows 11 didn't have this problem, and I don't have this problem on my desktop setup with windows 10.

I use a few addons: decentraleyes, ublock, duckduckgo and I have privacy protections set to strict. I have tried a few troubleshooting steps and the problem persists. Things I have tried:

• safe-mode
• fresh install
• installed additional codecs
• used user-agent workarounds to show as a chromium based browser
• turned off hardware acceleration

The problem doesn't happen on chrome, but it does happen on Edge, which is strange. Because of this, I'm wondering if there is something going on with codecs. In the firefox screenshot posted, the codec used is vp09, same with Edge. But in Chrome the codec is av01.

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".

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

I need to re-post this question as, although it has been asked previously, that session is now closed. It only started happening recently, but I'm not sure whether to blame the latest FireFox version, 96, or Windows 10, 21H2. I also run Avast and MalwareBytes AVs.

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.
