How can I eliminate the SEC_ERROR_UNKNOWN_ISSUER errors I get at multiple websites?

I just installed FF 63 on a 64-bit Windows 7 machine, and I'm getting SEC_ERROR_UNKNOWN_ISSUER errors at many, but not all, websites. Reaching the same websites via the same URLs using Chrome works fine.

All discussions of this problem seem to lead to https://support.mozilla.org/en-US/kb/error-codes-secure-websites?redirectlocale=en-US&redirectslug=troubleshoot-SEC_ERROR_UNKNOWN_ISSUER, but it's not helpful. My antivirus is Bitdefender Free, which appears to have no option for disabling the interception of secure connections.

Running FF in safe mode behaves the same as in "normal" mode: I get SEC_ERROR_UNKNOWN_ISSUER errors at many (but not all) websites.

Help? As things stand now, FF is pretty close to useless for me.

Hi. I just noticed that my browser had auto-updated itself to version 63.0, and now, videos on Youtube and news sites auto-play, even though I have it disabled in About:Config. Until today, all html5 videos were being blocked just fine by that setting. Why is this happening and what can I do to re-block videos from auto-playing?

FF recently updated and when it restarted my browser window is now not showing my menu toolbar or bookmarks toolbar even though they are checked to be on. Plus the minimize/maximize buttons are overlapping my tabs at the top. It seems I'm in some different sized view or something that I cannot figure out how to get out of. I am not in "full screen" view (already tried F11 to be sure). And I've tried dragging the sides out but that doesn't fix the top min/max button issue where it overlaps and my toolbars AND my MENU bar still do not show up. I've gone into customize and removed and then re-added the "bookmarks menu" but it only shows up next to the other icons, not in the normal "toolbar" format with my folders, etc. I can view my bookmark toolbar in the SIDEBARS but again it's just the top of my screen that's messed up and I know it has something to do with my min/maximize buttons being overlapped with tabs but can't get out of it.

I've put a screenshot below to show you what I mean. Any help would be greatly appreciated.

So there was an issue where my browser stopped automatically restoring my previous session after closing it. I followed some instructions I found online that told me to tick the option for it under Options -> General -> Startup, and this fixed the problem. However, this seemed to have caused my browser to directly close and stop asking me to save and quit even while browser.ShowQuitWarning is set to true in about:config.

If I tick off the option to automatically restore my previous session, however, I do get a warning that tells me I'm about to close my browser, but it only gives me the options to close tabs and cancel closing my browser; the option to save & quit is absent entirely.

That's about everything I know that could be related to this issue.

In the past few days, the block video autoplay option is not working. It had been working properly for years. I have video autoplay turned off in about:config and the option to block autoplay is no longer available under the settings menu. What settings need to be changed to re-enable this in the update. This is extremely annoying.

I have a new computer and I had previously saved a backup of the files of my Firefox profile. I followed the steps in this article: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles but it didn't work, none of my settings or bookmarks are in place. The backup profile had a different name so I copied the contents and I used the default profile that was created instead of creating a new one. Why didn't it work? Does it matter that I'm using the same profile from the backup on a different new computer as well?

My site uses a template engine to wrap standard page HTML around templates that contain only the body text. However utf-8 multibyte characters are displayed correctly if there is no HTML header but incorrectly if the standard page header, which explicitly specifies utf-8 encoding, is presented to Firefox.

https://www.jamescobban.net/templates/Articles/FrenchOccupations.html is the template of the body text https://www.jamescobban.net/displayPage.php?template=Articles/FrenchOccupations has the HTML header and footer wrapped around it. You can look at it yourself, but to save time the header added by displayPage is:

   
   
      
        <title>
	    ...text extracted by DisplayPage from the h1 tag...
        </title>
        <meta charset="utf-8">

I have Firefox 63.0.1 64 bit using Win 7. After the latest update, I frequently get the "performing a tls handshake" when trying to view a webpage. After 7 to 8 minutes I get a message saying "Secure Connection Failed. The connection to the server was reset while the page was loading. The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem." I've researched this problem and haven't come up up with an answer as to how to correct this. Does anyone know how to correct this?

This has been an ongoing problem that started, first with update 63.0, and continues with update 63.0.1.

I have tried multiple fix suggestions, including the very disappointing "refresh Firefox" option. While that did nothing to cure the problem, it did wipe out every saved password. That, to be blunt, really ticked me off. It says this fix solution will keep our saved information, with no mention of erasing passwords.

Second, I changed the Network Settings as directed, from Use system proxy settings to auto-detect proxy settings for this network. I have been cautioned NOT to use the no proxy option, because it has a chance of rendering some websites unavailable. Not interested in messing up my browsing experience any worse than these recent Firefox updates have accomplished by themselves.

All these problems aside, my biggest disappointment is in the total lack of communication from Mozilla. While I value the Firefox ideology and the mission to provide a more private internet browsing experience, all this is worthless to me if my pages load at something akin to dial-up speeds.

At this juncture I have no choice but to use Google Chrome until someone can provide me with a workable solution, a solution that doesn't send me back to square one with all my saved Firefox information. If that is the only remedy, I might as well switch my default browser now and begin to re-acclimate myself to the changes.

Thanks.

I have u block origin already.

I had media autoplay set to false. Now yahoo.com news autoplays vids (again). The autoplay literally started on October 24, 2018. 1- what happened to allow autoplay on yahoo when it was successfully blocked all this time? 2- what can I do to stop video autoplay? Idiot level instructions please- set one go here type instructions. I already went the "add on" route. Flash blockers didn't work at all. All other "vid blockers" are for youtube and will not work on yahoo news as I tried hoping one would work.

Maybe I am stupid, but exactly WHAT settings are needed to stop autoplay on yahoo.com that are in ublock origin or in firefox about: config settings (media.autoplay =false), which doesn't seem to have any effect anymore. Is something else in about:config needed?

Site example where annoy vid autoplay now exists: https://www.yahoo.com/lifestyle/dont-want-attention-mother-6-year-old-boy-whose-birthday-party-guests-no-shows-speaks-185110033.html
