I-Firefox Isithangami Sokwesekwa

I am getting a certification issue when trying to visit 2 specific sites which are some of the most visited sites in the web: https://www.google.com and https://www.youtube.com

The error it shows when trying to visit these 2 pages, is SEC_ERROR_UNKNOWN_ISSUER.

I have tried to troubleshoot it and follow the solutions recommended at: https://support.mozilla.org/en-US/kb/error-codes-secure-websites#w_the-error-occurs-on-multiple-secure-sites

however none of the solutions described in this guide worked to solve my problem.

In that guide, one of the suggested solutions is to scan my system for any malware. I used the following: Windows Defender Maleware Bytes AntiMalware Karpersky TDSSkiller however the results are all clean.

In the guide, it suggested that I check the clock as well. The system clock however is synchronized.

Last, I have resetted Firefox Profile but this didnt fix the issue either.

I shall note that the issue appeared yesterday and so far nothing helped fixing it. Not even the system restarts.

The issue about visiting these two sites, is limited only to Firefox.

I can access https://www.google.com and https://www.youtube.com without problems using Google Chrome and the Opera Browser.

Also, Google Mail and Google Translate work fine on Firefox. These two sites can be accessed with Firefox without causing any SEC_ERROR_UNKNOWN_ISSUER errors.

My tabs are constantly - several times a day, every day - crashing. I'm not watching any videos, I've tried a clean (deleted profile folder) install, and turning off hardware acceleration. It's not anything attached to my profile, as I sync with a 2nd computer that has zero crash issues.

My tabs are frequently crashing and some strange behaviors occur with firefox after these crashes (adblock failing to work until browser restart, browser going blank for a split second). My browser also occasionally crashes, and even more infrequently my entire computer will crash which usually happens after series of tabs crashing in a row. It may be a ram issue but I have no problems with any other programs on my computer so I doubt that.

Reviewed "Sheribee" earlier issue which apparently involved a VPN. I do not have a VPN but have tried several times in the past week to access IRS refund status site without success. I can get into irs.gov, but am unsuccessful in accessing the refund status site after entering required input data. The issue has occurred only this past week.

I'm unaware of IRS issues causing this problem.

Have not had this issue on any other sites; and I have successful retrieved data in prior years.

I am not saving any sign on protocols with the irs or any other sites.

Running Windows 10. Thanks for any help. BTW I did get refund information using the telephone, but I want to ensure there's not a hidden conflict of some sort with FireFox. Thanks for any help.

I'm seeing some weird behavior in FF.

I have an HTML page that allows the user to click on a link to trigger a file upload to a remote server. The file being uploaded is usually > 2GB and takes a LONG time to upload (sometimes > 1.5hrs due to slow link to remote server).

What we see is the remote server ends up with multiple corrupted versions of the same file.

Could it be that FF is silently timing out waiting for a HTTP response and then retrying to upload the file? I can't think of any other explanation for the multiple files, since the user only clicks once on the hyperlink.

Thank you, Dan

When I try to use a platform like Netflix i get repeated error messages that WidevineCdm has crashed. This happens also in other browsers. I am not very tech savvy, but I've tried all the solutions I was able to understand on here and through Google, but nothing seems to fix the problem. Can any one advise?

Not sure if this helps, but here is one of the many crash reports I've sent: https://crash-stats.mozilla.org/report/index/75e61622-4282-4a83-b86e-9861a0210422

Thanks to terrible, productivity-sucking changes in the basic functions of the FF browser, I have started using other browsers. First - FF updates far too frequently - almost daily. No option to block update notifications. Never know if it's something trivial, an important security fix, or a major interface change. The 'what's new' page is always incomplete. 2nd - FF downloads software surreptiously through the sneaky "normandy" back door and inserts feature changes irregardlessly. Doesn't matter if you explicitly selected NO to enrolling in studies. Users can't get a straight answer on how to disable Normandy. Named after the Allied stealth invasion of Europe, it does the same thing to our computers. 3rd- FF caters to fringe techie desires with an onslaught of unwanted or unsuable additions that bloats the software, uses up CPU, or inserts intrusive attention-seeking diversions. I am forced to spend too much time after each update to investigate how to shut off unwanted surprises as well as unannounced alterations to my option settings. For example, if I press the mute button on my keyboard a very large media window pops up and takes over a sizeable chunk of my computer screen. It cannot be resized. It has no close button. Took hours to find out how to disable this. 4th-FF developers seem to expect users to have the newest computer equipment, huge display screens, and lot's of extra memory. If not, too bad. 5th - the recent puzzling, arrogant changes to the basic print function is evidence of that mindset. FF developers say they aren't going to let users revert to the normal "classic" small foot-print pulldown menu on the left side of the screen to preview, set up headers, etc. Too bad if the open window is too narrow to view this new intrusive, real estate consuming right hand display. Too bad that you can no longer simply seamlessly interact and accomplish the task. Too bad that the FF developers think they know better than you that you should change the way you work. 6th Reader view is an obscure feature. I do not want to be forced to use it. I do my best to strip out or ignore the overwhelming number of pictographs competing for my attention, 7th - I can no longer see URLs in the address bar. You've truncated them. I am forced to cut and paste them into a text editor to see them in their entirety. 8th - Firefox hangs video streaming sites like peacocktv.com. Windows Taskmanager shows that FF forces CPU and hard drive usage to 100%. 9th -There is no mechanism to escape, break, or interrupt FF's failed video stream. How sad that Microsoft's obnoxious Edge browser is better at video streaming. It uses far less system resources on the same video streaming site. AND doesn't hang the OS. It's likely FF's new unwanted capability to launch multiple picture in pictures - which I don't use - hogs resources. 10th- How about beta testing using 'normal' non-super techie /gamer users? 11th -FF disabled user Feedback. I stopped updating Firefox. Not trustworthy.

I have suddenly started to experience a TAB crash in FireFox when browsing in private browsing mode. The crash happens on a specific page, and occurs almost 100% of the time.

I'm developing a web application, and I want to view the application in private mode as I switch between QA, PreProd and local development environments.

I have not yet experienced the issue in normal mode.

Hi all,

I'm having a repeat of this issue: https://support.mozilla.org/en-US/questions/1291551

Again some links from emails have been giving me the "Warning: Potential Security Risk Ahead" page with the error message "SSL_ERROR_BAD_CERT_DOMAIN". I get this in safe mode but not in private browsing. I have tried all of the fixes suggested last time I asked about this problem including deleting cert9.db but that hasn't worked this time (so maybe it wasn't the fix last time either).

To be explicit, I've tried all fixes on these pages so please don't suggest them again without providing an explanation about why you think it will work (a technical explanation please): https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can https://support.mozilla.org/en-US/kb/firefox-and-other-browsers-cant-load-websites https://support.mozilla.org/en-US/kb/secure-connection-failed-error-message https://support.mozilla.org/en-US/kb/connection-untrusted-error-message http://kb.mozillazine.org/Error_loading_websites https://support.mozilla.org/en-US/kb/what-does-your-connection-is-not-secure-mean https://support.mozilla.org/en-US/kb/websites-dont-load-troubleshoot-and-fix-errors

And also this one, which is actually related to the message (none of the above are): https://support.mozilla.org/en-US/kb/what-does-your-connection-is-not-secure-mean#w_ssl-error-bad-cert-domain

Hello, since a few month the browser is shutting unexpectedly every couple of hours and all settings like starting page or prefered search engine are lost. There is no error message or error report. I'm using lates MAC OS and Firefox version (it happened also with the last couple of versions)

Some time ago, firefox stopped launching. I tried everything. I refreshed, reinstalled, clean reinstalled, reset windows, deleted possibly interfering programs, and clean reinstalled windows (that was for other problems). I am running windows 10 home build 10.0.19042 (currently the latest) on a omen HP laptop 15-dc0xxx. It is x64 bit device with a intel core i7 8 gen cpu and a nvidia 1050 ti mobile. It does not seem to be a hardware issue as a linux kernel that I have dual booting with windows 10 runs it like a champ.

    When launched the application load for a period of ~7 seconds and for a frame or two there is a small window with either nothing on it or a safe mode window that goes away after a frame. When the problems started I closed firefox and reopened it a small bit later and the problems above happened. Windows safe mode will run firefox. Opera has very similar problems if that helps any. Google chrome, microsoft edge, microsoft internet explorer are all unaffected.

After having installed the latest Firefox update Firefox starts but it does not react to any link inserted for display.

If have tried all three help solutions provided but it does not react, also a new installation changed nothing

The error message is: Starter process deactivated after error.

Could someone please help to make run it again

P.S. It was not possible to get the Troubleshooting information as I could not write this request on Firefox but had to use another browser

The Widevine CDM 4.10.2209.1 plugin crashes every time in Firefox 78 browser. Was updated on April 21, 2021, maybe it's a bug? I'm not able to uninstall the plugin. Any help would be appreciated, thank you!

Hello, I'm on the way to be a web developer. But, when it comes to add Glassmorphism effect, it seems like firefox doesn't support CSS property called "backdrop-filter". Will there be any support for this in near future?

I'm using Firefox For Linux v88.0 (64-bit).

Anytime I try to upload a file (like a resume) to a website using the file upload dialogue, opening the file causes Firefox to completely stop responding. closing the dialogue box at that point causes Firefox to close. If I wait it out, Firefox does not recover.

I have reset Firefox. I have cleared my startup cache. I have restarted my computer. The problem has persisted for weeks despite numerous attempts at fixing it.

I can't upload a screenshot for obvious reasons.

Lately Malwarebytes is flagging firefox files for quarantine. I get messages like these daily now when I never saw any in the past many years of using Firefox and Malwarebytes.

Hello,

The cards of this home page desappears after the mouse over them. https://jessica-project-7813d5.webflow.io/

Is it a code problem ?

No problem with Edge and Chrom. Anyone would say me what happening ?

For a few days, Firefox has been freezing at certain pages and interactions. For instance:

• Hitting the "compose" button in outlook online
• Viewing this particular tweet: https://twitter.com/qrs/status/1383039053201870850
• Navigating to wikipedia.org

Other pages work fine. When the freeze happens, the whole browser becomes completely unresponsive, including the window controls. The following is printed in the console if I launch FF from console:

``` ExceptionHandler::GenerateDump cloned child 10319 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... ```

I am running FF version 88.0 (64-bit) on Arch Linux under Gnome on Wayland, installed through pacman.

What I have tried without success:

• Using a new FireFox profile (no extensions, history, cookies, etc)
• With and without WebRender
• With and without Wayland composition (`MOZ_ENABLE_WAYLAND`)
• All combinations of the two above
• Restarting the system, updating the system, reinstalling firefox
• Running mozregression

With mozregression I had the issue for all builds since `56f6da03c7e352f53fa923b30f66dfdf09a34116`, for all older builds I get the "Gah. Your tab just crashed." message.

I don't have issues with other programs or web browsers.

System locks-up when I go to Yahoo start page and try to scroll, though I'm able to get to email. This is the only site that crashes. Have to do a hard shutdown since HD and cursor are frozen. This has been going on since last FF update, maybe even the one before. Plug-ins are uBlock Origin and Video DownloadHelper. Anyone else experience this?
