SEC_ERROR_UNKNOWN_ISSUER for Google and Youtube

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.

Can't seem to recover my session

Hi,

I always have dozens of tabs opened, if not hundreds. They have vanished. I’ve been trying to follow the topics on the matter, such as the one named ‘Session won't load’ (questions/1254740), to no avail.

Finally, this time I remembered not to close Firefox when I saw my tabs where suddenly missing. I’ve never seen the ‘Restore the previous session’ on the Firefox menu, and neither did I this time. Without closing the browser, I did a backup of the ‘sessionstore-backups’ folder. It contains:

‘previous.jsonlz4’, from 22/11/2020 17:42 ‘recovery.baklz4’, from 22/11/2020 18:57 ‘recovery.jsonlz4’ from 22/11/2020 18:58 ‘upgrade.jsonlz4-20201027185343’ from 31/10/2020 13:42 ‘upgrade.jsonlz4-20201108180448’ from 10/11/2020 15:05 ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34

The one I need is ‘previous.jsonlz4’, since by 18:57 I’ve already lost my tabs. From the update backups I think I could also use the one from 22/11. In any case, I don’t understand what I am doing wrong so as to recover the ‘previous.jsonlz4’. This is what I’ve tried from different threads on my profile folder:

The ‘-backup’ and ‘OLD’ changes belong to different attempts

- Rename (on ‘sessionstore-backups’ folder) ‘recovery.jsonlz4’ and ‘recovery.baklz4’ to ‘recovery-backup.jsonlz4’ and ‘recovery-backup.baklz4’, and also tried with ‘recoveryOLD.jsonlz4’ and ‘recoveryOLD.baklz4’ - Rename ‘sessionstore-backups’ folder to ‘sessionstore-backupsOLD’ - Rename (on the main profile folder) ‘sessionstore.jsonlz4’ file to‘sessionstore-backup.jsonlz4’, and also tried with ‘sessionstoreOLD.jsonlz4’ - Copy/paste the ‘previous.jsonlz4’ file into the main profile folder. - Rename ‘previous.jsonlz4’ to ‘sessionstore.jsonlz4’

Nothing has worked. Once followed the steps, Firefox keeps opening my startup page. Note that it does not restore my previous session (that is, some tabs regarding this same subject), but my startup page, which means my attempts are having some effect, although not the desired one. I do have the ‘Restore previous session’ checkmarked in ‘Setting/General/Startup.

I also tried to replace ‘recovery.baklz4’ (on ‘sessionstore-backups’ folder) with ‘previous.jsonlz4’, from 22/11/2020 17:42, hoping to be prompted with the ‘Well, this is embarrassing’ + ’Restore’ window. I had no success.

I’ve been trying to recover my tabs for hour by now and don’t find what I am doing wrong. Why does Firefox refuse to load my ‘previous.jsonlz4’ file? Am I missing something? Maybe ‘previous.jsonlz4’ is corrupted or something? Should I try to use the ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34 file? (Although I would lose some information)

Some people talk about a ‘History > Restore Previous Session’. I cannot find anything similar.

Thank you very much

Many sites have videos playing when I open the page. If I just ignore the video and scroll down without explicitly stopping the video, I get a popup window playing the video. Apparently the popup blocker doesn't consider this to be a popup. Is there any way to kill this annoying behavior?

Hallo und guten Tag,

ich möchte gern mehrere websites als Startseite haben, wenn ich den Firefox browser öffne. Wie das geht wird auf der Firefox Seite sehr gut erklärt.

Zwar ist es mir gelungen, google als Startseite durch drag & drop auf das Haus Symbol zu ziehen. Jetzt würde ich habe gern weitere Registerkarten als Startseite festlegen.

Wenn ich (wie in der Erklärung) jedoch auf die Menüschaltfläche mit den drei Strichen klicke und danach auf "Startseite" klicke, ist das Fenster "Startseite und neue Fenster" leider inaktiv, so dass ich nicht weiterkomme. Wie kann ich dieses inaktive Fenster aktivieren. Wo liegt der Fehler.

Ich hoffe sehr, dass mir bei diesem Problem jemand helfen kann und würde mich über eine Antwort sehr freuen. Vielen Dank im Voraus!

Beste Grüße, Sabine

Good Morning

Today I had to repair Firefox and after restarting, I felt a strange scrolling sensation, it was not the normal Firefox scrolling, I even thought I had openend the wrong browser...so I went check about:config , and found some values where changed as new default values:

general.smoothScroll.mouseWheel.durationMaxMS 200 general.smoothScroll.mouseWheel.durationMinMS 50

I tought it was me the problem so I installed an older version of Firefox (80.0) in order to compare, and found a normal scrolling and those values:

general.smoothScroll.mouseWheel.durationMaxMS 400 general.smoothScroll.mouseWheel.durationMinMS 200

I think this is a mistake from devs, if i wanted to have horrible scrolling, I could just use Edge instead of Firefox, could you please bring the original scrolling back to Firefox?

Thanks

Firefox doesn't show sent messages in Gmail. Neither individual sent messages nor conversations that include sent messages. The message lists display fine, but when I try to open a message / conversation it only shows a blank page. Currently the version of Firefox on this computer is 83.0 (64-bit), although the problem occurs since the most recent versions. It only happens with Gmail. Yahoo! and AIM work fine. Doesn't happen in Chrome or Edge

Hello As others have said recently, Firefox has become unusually greedy in RAM!

I love Firefox and it's been my favorite browser for years and years. But there it became unmanageable for me!

I'm absolutely not going to spend money to add more RAM to my PC tower, which is only three years old, and otherwise performs perfectly well for my use with all my other apps. There is 8 GB of RAM in my PC, a fast model of RAM, very fast, and expensive. You have to stop, guys, and face the truth! There is a real problem and there is no point in denying it, and saying that it takes more than 8 GB on a PC at the end of 2020.

The CONCRETE result is that we are all going to change the browser we use, it's super sad, and it is happening NOW. I don't want to change, but I have no choice. It's kind of heartbreaking for me, believe me.

I selected the new HTTPS-Only mode in Firefox 83.0, and some URLs are being blocked, followed by the "Secure Connection Not Available" message. Yet, when I click "Continue to the HTTP site," the site URL is HTTPS, and the grey lock in the URL bar is in the fully secure position. Please let me know what this means, or whether this is a bug to be worked out. Thanks in advance.

Having an issue with youtube as of late on firefox. The ability to see "history" list, "watch later" list, or utilizing the save function do not work because I am constantly having to login. For some reason the ability to see lists or to utilize any functions on the youtube website do not work properly because I am unable to remain logged in. Is anyone else having difficulty with youtube?

Hi. I am trying to reach a site that I have in the past found a good reference site (if you like reptiles), Ian's Vivarium. I am in up-to-date Firefox for Win10, I have refreshed Firefox to no effect. Error message on the website is: "You are running an unsupported PHP version. Please upgrade to PHP 7.1.3 or higher before trying to install or update to phpBB 3.3" at the top of a wholly blank page.

I get the same error when attempting Chrome and Edge (which crawled back onto my PC uninvited)... maybe a website issue?

Help?

While not totally computer illiterate, I'm pretty close....

Thanks in advance?

Whenever I click on Print Edit WE button the edit page opens but all the buttons are inactive and the PE button in the toolbar shows SUS for suspend. Nothing I do fixes it. I've removed and reinstalled the lastest version of PE from the add-on web page 3 or 4 times. A right click on the PE button drops down a menu but the one I need, Edit, puts PE into suspend mode. What could be causing this? I'm running FF 83.0, 64 bit, Windows 10 Pro. Print Edit has always worked before. Does the latest version have a bug? Or does FF maybe have a bug?

Hi,

With recents versions of Firefox (I cant' tell which), when you type an adress and resolve of this adress failed, firefox is running a search with this adress as parameter. I want to disable this feature, as this can be a security problem when typing internal servers private urls. You have to put "http(s)://" to disable the feature I've separated main adress and search input, disabled autocompletion, but the main adress is still making searchs.

Issue: the bookmark toolbar arrow (the one that shows bookmarks that don't fit on the toolbar) is gone from my browser, and the toolbar itself seems truncated (only like 7/8 of the toolbar is filled).

I didn't change any settings or installed any add-ons that could have to do with this. It just disappeared one day, I didn't even notice it at first.

What I tried:

  • I launched Firefox in safe mode, didn't fix it
  • I removed my userChrome.css file, didn't fix it
  • when I cut the bookmarks and paste them into the toolbar, the arrow shows, but when I relaunch the browser it is gone again

See photo for what it looks like (ignore the anonymous favicons, I changed them temporarily with userChrome to preserve privacy, but without userChrome the issue still stands).

Anyone has an idea what happened and how to fix this? Thanks.

I'll occasionally run into Firefox auto-filling another website address I don't want, but I just figured out that it's Shift+Delete and not Delete to remove an auto-fill entry (a rather asinine change, I thought). Unfortunately, clearing out the unwanted address did not work and the address still auto-fills in the U.R.L. bar (see picture).

If deleting auto-fill entries doesn't actually work, what will?

I've always been curious about this, as well, but how does Firefox determine what address auto-fills if I type in a couple of letters? Does it keep a running tally of how many times I've searched for/visited a particular site and use that data? This would be useful to know for the future.

I need to send my PC to the vendor (FNAC) for reparation. I want to clean my confidential files before sending it. Concerning firefox : how to desinstal it from my PC only, and reinstall it after repair with all the previous parameters and setting already installed ( list of passwords, ...)

said differently, I don't want to cancel it definitly because I use it on another computer and I want to recover it after my PC repair.

If you can help me I will really appreciate
