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.

hello there and good evening:3 my husband and i are having this repetitive and extremely frequent bright yellow pop up with a robot that states "a webpage might be slowing down your browser." then the option to wait, or stop it. i've ran out of patience with this notification to the point to where even though i'de hate to, i would have no choice but to switch back to chrome just to stop being spammed by this pop up while im trying to relax. it happens more frequently on youtube and walmart.com, and i just want it to stop because it seems as if when it does show up, once it starts it never stops, and it actually slows down my webpage to the point of becoming unresponsive and stalling/crashing my only webpage open at the time. my husband has the same issue and we both use windows desktop. it only started appearing after the latest update. please, can someone help me make this thing go away? its very stressful and i cant browse in peace anymore on firefox. yes we have turned off all background processes, and we both have scowered settings troubleshooting for hours at a time to no avail, it just never stops and it behaving like a really bad bug.

I'm using a Surface Pro 7, running Win10H. Firefox had a brief period when I first installed it where the on screen keyboard would appear and work, that stopped after a few hours and has not worked since. I fiddled with the settings on both Firefox and my surface, though nothing has changed. Un/re-installing did not help, thought it could reset something. Any fixes or advice would be greatly appreciated.

For clarification, the Accessibility Menu on-screen keyboard does work, but the tablet-specific larger keyboard does not function. It does open and type in other applications.

Hi All

So recently I had some windows issues on my newer laptop and had to resort to going back to my old laptop for the time being. Before using it I restored the system to factory settings and such then reinstalled the newest versions of firefox and such then imported my profiles that I backed up from the new system.

Was working fine for few weeks but the last week or so I have noticed firefox has become sluggish in how it loads websites and such.

I have tried setting up a test profile and that new profile was reacting the same way very sluggish in loading pages.

I have also cleared my browsers cache wondering if that would help.

I have also tested loading pages in Microsoft Edge to see if it was browser or system related and Edge seems to be loading pages just fine so it has to be browser specific.

Any ideas what I should try next to clear this up as the sluggishness is getting old fast!

Thanks

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.

I had a different issue I came here for, but I discovered a very serious bug while I was writing my question, so I want to make sure this gets addressed first.

After writing my question, I clicked the "share data" button below. I got a message "We can't automatically get your browser's troubleshooting data, please try these manual steps. " Without thinking, I clicked the link to the "manual steps." Unfortunately, instead of opening a new tab, which would be the expected behavior, clicking the link took me off the get help form page (the page I'm on as I write this). What's worse, when I used the back button to return to the previous page, everything I'd written was gone. Obviously, the expected behavior would be to not take the user off the page in the first place, but if for some reason it did, to autosave the writing so it can be restored when the user returns.

This kind of bug used to be a lot more common in the early days, when I first started using the web, 25 years ago. I used to have a boilerplate describing the problem because I was sending reports of the bug so frequently. I've only encountered it twice, to my recollection, in the last 5 years. Firefox's website would have been one of the last places I'd ever expect to find a bug this glaring and elementary.

Thanks!

All the family use my PC with their own user accounts. Frequently Firefox goes slow and whenever I check 'About Firefox' I see 'Firefox is being updated by another instance'. This means that I have to log off all other users and then let my Firefox run an update check which, of course, normally just comes back with 'up to date'.

The problems are normally evidenced by Firefox just being very slow and/or only showing parts of the page and those parts changing as and when the page is scrolled.

This is a real problem with Firefox and makes it very unpopular with my family due to its unreliability.

Could not Firefox be set to only do an update check when it can actually complete the check and/or update.

Any advice appreciated.,

thanks,

Rob

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.

When I updated to Firefox 25.0.1 all my add-ons were gone so I downloaded some of them again. My problem is with Flashgot when I downloaded it I can add the Flashgot (thunderbolt) sign to the toolbar, but the Flashgot media icon (which looks like a cinema reel) is not visible.

So basically when I try to add add-ons I right click on the Firefox toolbar which gives me the option to "remove or add items" by dragging them. So I dragged Flashgot media (called FG Media) (which is not visible in the menu by the way) and predictably was not visible on the Firefox add-ons toolbar

Anyone know what's up?

When I run Firefox it just churns away and expires. Sometimes, if I just leave it, after ten/twenty minutes it will run v, v slowly. I have uninstalled and installed Firefox. I have the most recent version of Avira [14] and have removed Firefox and added to permitted applications, still no joy. Am writing this from another Browser. Also if I close Firefox and then try to restart I keep getting the Firefox is running... Getting seriously annoying now. I can only assume that Firefox is not quite up-to-date with Avira's version yet. The other browser runs without problem.

Any attempt to get to gmail (from google search click on gmail, gmail or gmail.com in url, etc.) results in Unable to Connect -- Firefox can't establish a connection to the server at mail.google.com. This happens only in Firefox running on Server 2008.

I have been googling problem and have cleared cookies, and re-installed. Still have this problem.

I can get into gmail from IE no problem and from Firefox that is running on XP. It is just my machines that are running on Server 2008. This problem just appeared around November 21st.

Thanks for any help!

I received an email from AppleID@customers.appstore.36.ca asking me to update my account info. As my cc expiry date had just changed so I thought oh damn I forgot. I put in my updated info, then when I hit submit, at least I think that was what was on the bottom, don't honestly remember, any way a screen for "Reported Web Forgery" popped up. I got out of there I did not go any farther but did my information go anywhere? Looking closer at the email, there it DHgate.com web address at the bottom. Please put my mind at ease! Thank you. I just need to know if my info went any where.

I have a sony vaio duo 13 which is a sliding laptop tablet hybrid. I run nightly on the desktop for all my web browsing because i guess i am what is called a power user. I need all the options and features that firefox gives us, and don't care for the barebones yet more fluid experience of the Metro app. My problem is that when I am using Nightly in Desktop it runs great, but anytime i close my screen (which doesnt close in the traditional sense, it folds the screen out) and transforms it into tablet mode, it launches the Metro version of Nightly. If i was using the desktop version it transfers all my tabs to the metro app. and when i open the screen to laptop mode, it simply closes everything. AFAIK i don't remember installing the Metro version... I can go to the Start Screen and find the metro app but i am afraid to uninstall it because i think it will uninstall the whole Nightly Application, which i dont want to happen. I created an administrator account and went to the MetroApp repository on the harddrive but there is nothing there related to nightly or firefox so i can't just delete it.

Hi I'm having some issues currently with my Firefox v. 25.0.1. As soon as I start the browser up, it tries to load the restore session page from the previous crash. Pretty much before the page could fully load Firefox would crash.

I have tried to create a new profile and the new profile seems to work just fine but as soon as I try to copy the sessionstore files from the crashing profile to the new profile, the same thing would happen. From time to time I would be able to get the browser working but that's maybe once in 25 or so attempts where it actually loads up correctly for me to restore my past sessions.
