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.

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.

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?

I've installed the latest version of Firefox. Firefox Quantum 63 x64 and ReCaptchas don't work properly. It has been installed on a fresh Windows 10 Pro and Firefox it's at the same time a fresh install like I'm showing on the video at the end of this post. No firewall, no antivirus, no addons, nothing that should stop Firefox from automatically do the ReCaptcha. But every time you click on I'm not a Robot it always prompts you to do a puzzle.

Please Firefox, fix this issue. It is pretty frustrating to have to answer every time a puzzle that are ridiculously annoying or having to switch to Google Chrome to use those kind of pages that ask you to answer a ReCaptcha.

However, if there is anyone that has a solution, please share it with me or all of us. Because I've been trying to find an answer and haven't find one that works. So I will appreciate a good fix for it.

Thanks in advance to the community and hopefully Firefox finds a fix because for what I've read it's a persistent issue with other older versions too.

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>

I have added https://addons.mozilla.org/en-US/firefox/addon/gfycat-click-to-gif/

It shows up in the Extensions section under "about:addons" and it is enabled. However in my toolbar, there is no icon for it and therefore I cannot use it. I've tried using the "Customize" feature but none of my extensions show up there, so I cannot drag them to the toolbar.

I would attach screenshots, but even that isn't working on this support page form.

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

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?

I see the download in the history (strg-j) but there is no progress. I encountered the same problem at another site.

Is there a problem with downloadlinks beginning with http:// ???

In Chrome for example the link works without any problems
