Hi Everyone, IPv6 not working in Firefox, but in Google Chrome, Windows CMD, Microsoft Edge, and Opera is working fine, I'm using Cisco Secure Client as a VPN Client, and connect to the VPN IPv6 will enable and you can use IPv6 easily, but in Firefox only IPv4 working, and the problem only in Firefox

Hello everyone,

I started using firefox actively a year back or something like that, last couple of months it started driving me nuts as it started updating every time I launch it, which is very annoying even if it takes only 10 15 seconds, I sometimes need to check something really quick and I have to wait for it to finish installing an update, even though I checked the setting for it to do so in the background, it seems to only do it after I launch it disrupting my workflow, which made me switch back to Chrome temporarily, is there a way to fix this?

Keep getting this on a number of websites. Most of them I have used for years. Can't give the websites as there are too many but some are pitchsidemanager.com, hattrick.org, skysports.com and sportinglife.com . Just four of at least 14 give the Hmm. We’re having trouble finding that site message. I use No Proxy and have my anti-virus turned off when I get the message. I have tried various other proxy settings but the same thing happens. The thing is that I have to keep refreshing the page until it does actually connect and that can take a good few minutes. Sometimes I have to restart the browser. Why is this happening since the last few updates?

I broke an old computer and have my logins from it on a backup drive in logins.json and key4.db. I can't work out how to transfer these logins to my new computer. I've tried creating a new firefox profile since I am nervous of losing logins that are on my new computer, but then I am totally lost.

I updated my Firefox today and now videos do not play.

I had this problem back in April after an update and I spent weeks troubleshooting it. Eventually I got it to work after trying all of the following (then, and again now):

Things I've Tried: 1.) Clearing data (cache and cookies) 2.) Turning off "Strict Mode" 3.) Running CCleaner 4.) Disabling/enabling HW acceleration 5.) Checking that the DRM box is checked (and trying it without it checked) 6.) Refreshing Firefox 7.) Uninstalling/Reinstalling 8.) Updating my Windows install 9.) Updating drivers 10.) Disabling all Firefox extensions 11.) Running without extensions 12.) Running in Firefox Troubleshooting Mode 13.) Running Windows in Safe Mode with Networking 14.) Running a fresh install of Firefox without signing in after deleting all traces of Firefox from my PC (including Program Data folders, registry entries, etc.)

What finally worked back in April was to dive into "about:config" and change "media.rdd-processenable" to "false".

That fix does not work this time around.

In the meantime I've been using Brave and having no issues. I've tried video playback in Chrome, Opera, and Edge on this computer with no issues. This playback problem is exclusive to Firefox.

Video playback still works just fine on my 4 home PCs running Windows 10 and Pop_OS (3 self-built, one Asus laptop) using this same build of Firefox.

Other/Rant: I suspect this is a Firefox/Windows 11 problem. Most likely this is not something I can fix myself, but it's incredibly frustrating since I'm buried deep in the Mozilla ecosystem and use it for work. I'd prefer not to have to swap between browsers just so I can watch videos; too many windows open on this tiny work laptop isn't fun to juggle. Basic video playback is the #1 thing I use my web browser for at both work and home so it'd be nice if this irritating, months-long, unacceptable issue were resolved. A modern browser that has video playback issues? What good is it then? What's most irritating is that it seems I'm the one of a very small number of users with this issue, since I see very little posted about it online.

I've been a Firefox user primarily for almost half a decade now - moved over from Chrome for privacy issues. Never had a problem until 4/22 of this year and considering it's still an issue 3 months later... it has me re-evaluating the reliability and my commitment to an otherwise amazing browser.

I have sent several emails and get no reply, how am I suposed to fix check or see my saved passwords if they all look like this...3b4a3f36-7056-4eee-bcb3-2b0838fa07e1

I've encountered a very weird behavior: when selecting where to save a file or selecting a file to upload, the browser hangs 100% of the time.

Even when I go to about:memory, click Load, the path selection window appears - regardless of whether I select a file or close the window, the browser hangs and the window stops responding. I tried waiting for several hours - to no avail. Only restarting helps. Same with the upload selection window - regardless of whether I selected a file to upload or closed the selection window, the browser hangs. Before freezing permanently, the mouse cursor stops moving, then lags around a bit before recovering.

I tried cleaning download history, cache, recreated profile, restarted without extensions, in safe mode, disabled antivirus - always the same result.

Please advise me, maybe someone has encountered something like this - I really don't want to start using Chrome. My OS is Windows 11. Thanks in advance.

I searched Microsoft forum and opened the first link (https://answers.microsoft.com/en-us). On Firefox, Go back one page (back arrow) button was not working on this website.

Trying to use ProctorU with Firefox 104.0.2 on Windows 11 Home, and I am getting the following message : "Monitor Count : You may only use 1 monitor during your exam. Your monitor count could not be found". I searched for possible fixes, and someone mentioned removing fingerprinters, and possibly also remove cookies and tracking content from Firefox enforcement. I removed all 3 and that did not help. I also tried clearing cookies and site data and also cached web content, this did not help. Is there some other setting in Firefox that might be preventing the detection of the monitor count? Any suggestions on how to fix this issue?

Hi, I am unable to acess this website and get the following error. About 10 days ago access was ok, but it suddenly stopped. Is this a broswer issue or a ISP issue or both ? HTTPS://KE9NS.COM

The option to restore tabs and windows is no longer working for me. I normally have a dozen tabs I work thru every day. Yesterday when I shutdown Firefox, all those tabs were there. Today when I open Firefox it only had to single Firefox default homepage. Checking under History there is no option to restore previous tabs, and the recently closed tabs was empty.

To test, I opened an IMDB page and pinned it. I then went to Wikipedia. This gave me a pinned and unpinned tab. I shutdown Firefox via the "X" to close the window. When I restarted Firefox there was only the default homepage. Neither IMDB nor Wikipedia showed up under recently closed tabs and no option to restore the previous session was available.

I have operated Firefox this way for several years. I don't know why this behavior is no longer being supported.

I'm using a new laptop so everything is a fresh install. A few of the newsletters I've signed up for are now using GetResponse for their marketing. Any link I click on in these emails leads me to a "The page you're looking for doesn't exist" error 404. No matter what I try (disabling all extensions & setting Firefox's config setting 'extensions.blocklist.enabled' to false). Both of the companies that send the newsletters as well as GetResponse don't really seem to care and just blame Firefox. Can anyone help me fix this... if in fact it's something on my laptop that's creating the issue? I only use Firefox browser... nothing else and would hate to starting using some unsafe browser just to access these links. Thanks.

Had it yesterday, happened this morning after the restart and just NOW, when I entered 6 lousy tabs, and they are NOT in the recently closed list either.. wups, gone, no tabs, setting has a check mark on open previous windows and tabs. Within 24 hours, lost the tabs three times with a non reported crash and Firefox closing itself with no warning.

I honestly do not think I am responsible to keep a backup of my browser history, I expect a browser to do that. I switched from Opera to Firefox not to long ago.. even Opera is a security risk.. at least it doesn't delete your tabs just for fun.

Very simple.. that happens once more and i am OFF this browser....

There was no such problem before, after the 117 update, the CSS theme I use is constantly reset and the browser returns to its default theme. The screen goes black for a moment and then the theme resets or the browser crashes. Is there anyone who has experienced the same problem? Any possible solutions?

I'll add 2 pictures of what my browser looks like when normal and crashed.

My Firefox browser automatically updated a few days ago. Since the update, the browser now crashes repeatedly during basic browsing, making Firefox essentially unusable. For instance, retrieving Yahoo mail, reading articles, accessing login pages -- the page will enter some type of refresh/reload cycle and crash the browser.

I opened the browser in troubleshoot mode and the problem did not occur. Following the Mozilla instructions, I disabled extensions and reopened the browser normally, and the crashes continued. I have not taken any additional actions.

This problem began immediately after the latest browser update on 9/13.

I used to be able to send tabs between my devices, say when I go from my home computer to my laptop. This option seems to have gone missing, like I don't even see the option when I right click on a tab. What happened to this option? Did I somehow disable it? Can it be restored?

Good morning. My Firefox version is 117.0 and I am running Windows 11 Home. Currently except for Ublock all my other addon icons are grayed out on my toolbar. My webadvisor, Capital One, just gray. This is a new behavior and I'm not sure what happened. I am also curious why just Ublock is colored in. Thanks in advance for any help you can give.

Back in November 2023 I had the misfortune of a software engineer not doing his job correctly and he reinstalled the OS on my laptop instead of repairing some software that wasn't functioning correctly. Mercifully, I have had Microsoft support working on recovering my data, which has proved a tremendous task. 4 months and counting.

We have now finally managed to recover my passwords for my browsers, but they are encrypted. Microsoft Support have therefore asked if Mozilla do a decryption tool as they cannot open the file without it being decrypted first. If I was using Microsoft Edge, they would have been able to assist as that is a Microsoft product, but as Firefox is a third party application, they've asked for assistance. By the way, these are NOT scammers or hackers 'helping' me, but Microsoft support and I get everything emailed about our support etc.

Thanks in advance.
