Dear all,

For some time now my Firefox browser is crashing while I use it. Then a loop starts where a window appear with buttons offering to Restart or Close Firefox but whichever I choose it takes several sets of open/crash to stabilize when in the end if offers to either open it again, or refresh Firefox. I don't wan to refresh because I have tens of tabs that I want to save. But I can't because OneTab, along with all other extensions, is being disabled after the restarts.

I have a crash ID of one of the latest occurrences of this phenomena: f6ef62ad-b072-46b8-8bc8-0d3ca0240708

Please advise!

I noticed my laptop was being slow, so I looked at the memory usage. Firefox was using a whopping 5GB of memory on Windows 11. I then looked at about:process and it reported that extensions were using 4GB. I disabled each of my extensions and it still said it was using 4GB of memory. I then uninstalled two of them and re-enabled some extensions and it dropped to 781MB. This is still to much in my opinion, and I want to know how to figure out which extension is being so wasteful. Even a technique on how to figure it out would be appreciated.

Hi.

Ever since I upgraded to version 123.0.1, I am constantly getting slowness on websites stuck in "Performing a TLS handshake..." Eventually the websites load, but it's frustrating. I have read about the various solutions and have tried the following: Disabled IPV6 Refreshed Firefox Reloaded Firefox Disabled and removed all extensions Restart in safe mode Create new profile

This was not happening in version 122 and before. Microsoft Edge does not have this problem, but I prefer to use Firefox. I am running Windows 11 Pro. Any ideas?

Thanks

I am trying to reach an internal company website ([URL]), with a certificate chain rooted in a company certificate authority. This works fine in Chrome, and worked in Firefox on my previous computer. But i recently got a new machine, and something somewhere is not quite right. I get an error message looking like this (between the ~~~s):

~~~ Someone could be trying to impersonate the site and you should not continue.

Web sites prove their identity via certificates. Firefox does not trust [URL] because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

View Certificate ~~~

If i click on the error code, i get these details:

~~~ [URL]

Peer's Certificate issuer is not recognised.

HTTP Strict Transport Security: false HTTP Public Key Pinning: false

Certificate chain:

[certificate]

[certificate]

[certificate]

~~~

If i click 'View Certificate', i get a chain of three certificates:

1. Subject common name = [certificate]
2. Subject common name = [certificate]
3. Subject common name = [certificate]

If i go to Settings > Privacy & Security > View Certificates > Authorities, i can find both the [certificate] certificates. As far as i can tell, they are identical - i can open the certificate from 'View Certificate' and the corresponding one from the certificate manager and flip between tabs, and all the details are the same.

I am using Firefox 120.0, via a flatpak, on Ubuntu 22. I have given the flatpak access to /etc/ssl/certs, where my company's internal CA certificates are located.

To me, this seems like it should all work. The server has a certificate signed by an internal CA, which is signed by another internal CA, and both those internal CA certificates are in my certificate manager. So what is going wrong? Is there any way i can debug this?

Firefox takes a very long time to open the first tab. After it opens, subsequent tabs open relatively quickly. I've tried self help suggestions like clearing cookies, cache and history, updating, even removing home page content. Nothing helps. It's getting intolerable and I end up switching to other browsers rather than sit and wait. Starting to even dread using firefox. Running Sonama 14.3.1 on my iMac. What else can I do?

I'm asking this question on a different browser because Firefox cant load any websites.

Basically whenever i open a new tab, it opens to a crashed tab. Gah. It cant even load google, or any website for that matter, not even the homepage for Firefox, its just a blank page with nothing on it, whenever i type something into the address bar and press enter it just disappears and does nothing. Browser settings work, but stuff like passwords dont, and i have most of my important passwords on firefox, so i cant log into runescape and stuff.

Can you help?

I am using Windows 10 Home on an HP laptop. Some months ago, I began getting this error message when trying to start Thunderbird: Your Thunderbird profile cannot be loaded. It may be missing or inaccessible. I've been slogging along using my Gmail reader since then but I need my address books from TB for my business. I really need to get this fixed.

I've read all the questions/replies on this and have uninstalled and reinstalled TB. My Appdata/Roaming/TB file only has 5 files in it: Crash Reports, Pending Pings and Profiles plus a couple of 1 KB config files. Don't know if this is right or not.

When I search the Profiles folder using .ini, I get this Notepad info:

[Install8216C80C92C4E828] Default=C:\Users\*\Documents\yvfr1fi4.default Locked=1

[Profile3] Name=thunderbird IsRelative=1 Path=Profiles/kavosmqu.thunderbird

I have this yvfr file on a thumb drive and I tried uploading that into the roaming/TB file but I still get the same error message.

Any help greatly appreciated! Thank you.

My Firefox tab keeps crashing on a particular website. Whenever I go to twitch.tv, the site begins to load and then I get the "Gah. Your tab just crashed." screen. I'm only getting this crash on twitch.tv pages, and this issue just started on May 31, 2024. When I try to open a twitch.tv page in Private Mode, the page loads just fine. I've never had a Firefox tab crash prior to this.

I've tried turning off all of my Firefox extensions, but that didn't solve the issue. I also tried opening Firefox in Troubleshooting Mode, but I still got the tab crash. I'm using the latest version of Firefox as of today's date.

Hi,

First, this is not a complaint. Firefox is an outstanding product that makes me very happy.

I though I could post the following, because this community strives to make it better.

In a nutshell, I have a very fast Internet connection, up to 6Gbs/1Gbs speed, and Firefox is not able to go over .9/.8

I attach are 2 tests, one with Firefox and one with Chrome.

Note that when using it for anything else than speedtest, Firefox does not feel slow at all.

I'm not requesting a fix, just thought that somebody would like to know.

So I have a following problem

FF 124.0.1 Windows 10 N edition Installed media feature pack

When trying to play twitch video it shows error 4000 and when trying to play stream from youtube it shows that your browser can't play this video.

Problem is that FF was able to do it like 6 moths-year ago (not really watching stream videos)

was trying to reinstal media feature pack, firefox, chcecknig nighgtly build but without sucess and have no clue what can do more

Hi

I've been having an issue logging into Gmail using Firefox. I've used both Gmail and Firefox for years and have never had a problem, but I now get stuck in an endless loop on the Gmail login page. I select my account, enter my password, then get sent back to the account selection page.

The problem seems to be relating to me trying to link two Gmail addresses so that mail from one is forwarded to the other. I set up one account this way without any issue, but when I went to do it with a different account, I got an error code. After that, I was logged out of Gmail in Firefox and haven't been able to log back in.

Things I've tried so far:

• Using a different browser. I can log in without issues in Chrome.
• Logging in with a different method. Neither my password nor my passkey work.
• Logging in with a different Gmail account. All of my accounts seem to be stuck in this way.
• Disabling all my extensions. This doesn't help.
• Clearing Firefox's cache. No luck here.
• Restarting Firefox and restarting my PC. Turning it off and on again doesn't fix it.
• Contacting Google support. They said they think it's a browser issue as I don't have any problems using Chrome.
• Using Firefox's private browsing mode. This does work and I can log in to Gmail. However, I don't know exactly what the problem is because I've disabled all my extensions and cleared the cache in regular browsing mode and still can't log in that way.

So I have a partial solution (using Firefox's private browsing mode) but it's not a long-term fix. What else can I try? Has anyone else seen this problem before and been able to fix it?

I've been using TB since the beginning, so like 20 years now, congrats! (to me 😜) Now I have at least 10 accounts and hundreds of folders and everything was fine until I started archiving some old messages in one account, and TB began creating new archive folders like YYYY/YYYY-MM which were being included in the Global Search/indexer by default. So I went to the properties of each folder and unchecked the option to include it in the Global Search results. I could see in the Activity Monitor the indexing of that folder would stop and go on to the next one, until I disabled all 12. Now TB is indexing over 100,000 messages but it doesn't say what folder these are in, I can't seem to find it.

What I did find is the global-messages-db.sqlite database which, after closing TB, I made a backup of, then I found the folderLocations table with hundreds of rows and the IndexingPriority column which had various values of: -1, 20, 40, 50, and 60. I set them all to -1 and TB is still trying to index over 100,000 messages somewhere. Where? and how to stop its madness?!

Dear friends,

I have Firefox Browser 127.0 (64-bit) installed. IFRAME is not displayed on some websites.

Example: https://www.rollerfreunde-untermain.de/gaeste.htm

Attached you will find a screen shot.

Can anyone say why this is the case?

Kind regards Uwe

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

Video playback initially works, until suddenly it doesn't; no new videos will work, and videos that previously played in the same browsing session will stop working. Easy to reproduce on Reddit by browsing any video-heavy subreddit. Leaving a broken video in a tab seems to infect the rest of the browser across websites; if a broken video from site A is open in another tab, videos on site B won't play.

Sometimes quitting and restarting Firefox is enough to temporarily get video playback working again; sometimes I have to manually clear the browser cache; at least once I've had to reboot my phone.

How can I turn this message off? Some sites I visit give me that message, it shows up when I'm typing a reply to something which pushes the page lower and fouls up my ability to keep typing, then if goes away, comes back, goes away ... I just want to kill the message entirely. I'm not worried about speed, there's nothing to fix, I just want the message gone.

When I open Firefox. Firefox Will NOT open any websites. If I disable ublock origin then enable again Firefox works but I get all the ADS. What I have to do is: Close firefox and restart Firefox but then I get this message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." Sometimes I have to restart Firefox as many as 10 times before Firefox works. I got to the point where I stop after the second try and just switch to Brave browser.

Before: Firefox use 99%. Brave Use 1% Now: Firefox use 75%. Brave use 25%

I've been running Thunderbird for years on Gentoo which has version 115.10.1 as the most recent. I don't send much mail so I'm not exactly sure when this problem occurred, but I'm unable to authenticate with my SMTP server. I have not changed any configuration. Some weeks ago a changed my password on the server, but I made the appropriate changes to Thunderbird password manager. All settings, username and passwords are 100% correct as I copy pasted all of them. IMAP on the same server (uses same credentials) works.

I have tried deleting and re-adding my accounts which did not help. I have also tried deleting my profile folder. All other mail clients (e.g. claws-mail, kmail, mailspring) with the same SMTP server don't have any problems sending mail. This problem seems to only affect Thunderbird and Thunderbird forks such as Betterbird.

I have no firewall and am using SSL authentication with cleartext password on the SMTP server.

I get the following output to console on attempted sending of message:

console.error: (new Error("Server error 503 Service Unavailable", "resource://services-settings/Utils.sys.mjs", 390)) console.error: mailnews.smtp: "Command failed: 535 Incorrect authentication data; currentAction=_actionAUTHComplete" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.smtp: "Authentication failed: Incorrect authentication data" console.error: mailnews.send: "Sending failed; Unable to authenticate to Outgoing server (SMTP) mail.kapsi.fi. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'., exitCode=2153066805, originalMsgURI="

My issues:

1) Every time I close Firefox I get the Mozilla Crash Reporter telling me that Firefox has crashed. Sometimes I even get the Mozilla Crash Reporter when I start Firefox. But Firefox is still there.

2) When I turnoff my Comodo Firewall, Firefox has no Internet connection.

I have done clean uninstalls/reinstalls over and over. I go thru and adjust settings. My other browsers work fine, including WaterFox, WaterFox Classic, and Vivaldi.

I tried turning off my security software to test. Specifically exiting Comodo Firewall seems to have caused Firefox to not have an Internet connection. All other browsers have Internet access except Firefox. And the Crash Reporter cannot "report" when the Firefox Internet connection does not work, though I did have it report many times when the connection DID work.

One other clue: In Task Manager I see that even though I have closed Firefox, there over 20 instances of it still running. When I try to open it again, I get the "Firefox already running" error message. When I try to kill these instances/processes many will not close.

This problem has been persistent for more than half a year since I built my new PC. I am on Windows 10 LTSC. Besides Comodo Firewall, Emsisoft Anti-Malware is my main anti-malware.

Please help! Thank you!

Hi,

I am using Firefox for Linux, and whenever my yubikey is plugged in, firefox will start bothering me for a pkcs#11 password. It always happens on start-up but it gets relentlessly annoying if I happen to be on a site which potentially utilizes certificate auth, which I do not use this yubikey for.

I do however use it for 2fa, which does work perfectly fine.

How do I permanently stop whatever Firefox process keeps bothering me about this PKCS#11 password for functionality that I never use?
