Facebook, google ERROR sec_error_unknown_issuer in Fresh Firefox 35 windows 8.1

Windows 8.1 64-bit
Firefox 35 (Latest)
- Fresh Installed firefox 35
- Even refreshed Firefox with safe-mode
- when opening page google.com, facebook.com (Attached Image) getting error page that should not be the error/exception.
- This is not for the first time even in past I had got this error for google.
Why firefox developer is neglecting this every time they introduce newer version.?

hello raviparekh027, thanks for providing the screenshots.
as this problem might have different external causes please provide another piece of information:
when you attempt to add an exception on the bottom of the error page (don't do it for real though!) & inspect the certificate, '''which issuer information''' does the certificate contain? (see screenshot)
thank you!

Firefox window spins around the screen

Hello:
I made a typing mistake while using the Firefox web page, made a typing mistake, and tried to backspace the error. However the Firefox window spun around on the screen a couple of times, then stopped.
I wasn't able to see it happen again. I am running version 19.0.2
Have you seen this reported before? Do I have an issue with a virus? I am running McAfee Security SiteAdviser, and it is current. It did not find an issue on its last scan.
Thank-you
Derrick Williams

Hello:
Thank-you for the information. I don't go into questionable web pages. The last web page I had looked at was the London Gazette and was looking at information from WW2.
http://www.london-gazette.co.uk/search
I had checked McAfee SiteAdvisor before entering the site, and selected a link to view a list of published medals (070409 Medal Start Dates.doc).
I haven't had the issue again - I ran a full scan after it happened. I will contact McAfee Support and see if I can verify that my Security software has not been compromised.
Thanks again.

Firefox error "sec_error_unknown_issuer"

After years and years of using Firefox, I decided to leave it and start using Google Chrome.
Why ?
Because Firefox returns error "sec_error_unknown_issuer" very often, when I access to my usual websites.
Something must have been wrong with last Firefox update.
Getting these SSL errors on every other site is starting to really get annoying! There is nothing wrong with the SSL certificates or the sites. It's your browser that is unable to verify the certificates.
When you fix it, maybe (only maybe) shall I return to Firefox.
Have a good day.

hello, this is most probably caused by external factors and a possible solution depends on different factors. please attempt to add an exception on the bottom of the error page & inspect the certificate (see the screenshot attached for instructions):
 which '''issuer information''' does the certificate contain?
thank you!

Marla,
Sounds like you hid the Menu bar. Hit the '''Alt''' key to show the Menu bar, then open View > Toolbars and select Menu bar, so it has a check-mark.
Anonymous,
Open the View > Toolbars menu and select what you want to see.

When I click on an Icon on my desktop to take me to a site (such as google) I get a message that it could not find the loaction. Then it goes ahead and opens a Firefox window with the site anyway as if the message never happened.

When I click on an Icon on my desktop to take me to a site (such as Google) I get a message that it could not find the location. Then it goes ahead and opens a Firefox window with the site anyway as if the message never happened. Then when I close the window I see that the message is still there. I have to close it separately. Any suggestions? Oh, and this only happens if Firefox is NOT already active. If I have another Firefox window open when I click on the Icon, it just opens as expected. This message appears no matter which site Icon I select. It did not happen before I upgraded to ver 9.0.

Hello BassoonPlayer,
Since you are using one of the the school's Macbooks, it is quite possible that the time and date are not properly set on the computer that you are using. FaceTime will not work if you do not have the proper time zone set up for the location that you are in. This past week, there were a two other Macbook users I've helped by simply telling them to set the Date/Time properly. By the way, you described your problem very well, which makes it easier for us to help you. Hope this solves your problem -- if not, post back and I can suggest other remedies.

I get error messages frequently when changing windows or starting firefox

this is the fourth time i'm trying to contact you guys. i keep getting error messages when i changed windows saying oops this is embarassing... etc. try again button works sometimes, sometimes not, if not have to restart, erases my bookmark menu tabs which i LOVE, and sometimes they come back. i love you guys so much more than internet explorer, but i have had to use internet explorer now almost all the time because of this problem. also, if you could make it so that one can delete blocks of unwanted email (like click the first unwanted email and the last one and then control/shift like in the old days) that would be AWESOME, but i have found that i can't do this in other applications anymore either so maybe it's something windows operating systems took out as they make new versions, but if you guys could create it in your email site wow, everyone would LOVE YOU!!!!!! so many do already, all my IT guys use you and my friends who are halfway computer literate. i hope you can help me with my problem, also i think i read you partner with clients for their websites to improve/add features. is that true? i'd love to do that if so, i'm using go daddy now, and haven't done half the stuff i want to do on my site. thank you for your positivity and you guys make up for those nasty virus makers who wreck people's lives, businesses,.. using their brilliance to harm people, it so sad. thank you again. i hope this goes through this time. i think i'm going to copy and paste it this time on Word so I can mail it to you if i screw up again!
thank you again so much!

Just updated to firefox 5.0 and my google toolbar has disappeared, went to reinstall it and error message says google toolbar is incompatable with firefox 5.0. Any solutions? Thanks

Last night I opened firefox and it said there was an update (5.0) available, so I updated. When I opened the browser this morning the google toolbar was missing, so I went to the google site and tried to download the google toolbar for firefox. A message appeared in the next to a piece of green jigsaw saying the google toolbar is incompatable with firefox 5.0. Is there some way to make it compatable? Regards, Peter.

You would need to install the Addon Compatibility Reporter, but you need to start working on those workarounds because ...
'''The Google Toolbar is no longer supported by Google in Firefox 5 and up''', you may be able to get what you want from it for a limited time, the directions to install the Google Toolbar were posted before Google actually announced dropping support.
*Enable Google Toolbar in Firefox 5 http://googlesystem.blogspot.com/2011/06/enable-google-toolbar-in-firefox-5.html
*the-edmeister posted a brief evaluation of the situation https://support.mozilla.com/en-US/questions/841736
In any case you can find several alternative solutions, and you can start working on them now, see
* "'''Using Google Toolbar features without toolbars'''" http://kb.mozillazine.org/Using_Google_Toolbar_features_without_toolbars

Certain websites will load eg. Facebook, Google, etc. but others, eg. YouTube will not open. Why? And how can I fix this?

Firstly, I downloaded the latest edition of Firefox. It then crashed several times in a row. This is when certain websites stopped responding and refused to open. I don't know what the criteria are for which websites open and which do not as I have no problems with sites such as Facebook, Google, etc. yet sites such as Youtube won't open.
Also, If I search for something on Google, once it returns results, I cannot open certain websites from the links given to me by Google.
Eg. if I search Google for Musicnotes.com, I can click the link and the page will open. But if I search for my university website, the page won't open.
When I closed Firefox and went to reopen it, all I got was the "send error report" screen several times over. If I clicked "Close" or "Restart" Firefox, nothing would happen, it just returned me to the "send error report" screen. I then restarted Firefox in safemode as well as restarting it without add-ons. But I am having the same problems with opening websites.
What can I do?

Do a malware check with several malware scanning programs on the Windows computer. 
Please scan with all programs because each program detects different malware. 
All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.

How do I block an ad that opens up a new Firefox window and keeps telling me my system performance is poor? I can't even capture the link.

This particular ad, supposedly from a Windows Certified Partner, opens in a second Firefox window and keeps flashing the message that my System Performance is Poor, wanting me to click on their ad and let them do whatever nasty things they want to my system. I have not been able to capture the path but next time it comes up, I will write down all that I can see.
If I have closed my main Firefox screen first, and then close out this ad, the next time I open Firefox, the ad opens and all my standard tabs are gone, requiring me to reopen each one seperately (Facebook, Google, etc).

Just to address the last point: check your History menu to see whether you have the Restore Previous Session option and use that if you can. If that is grayed out or doesn't restore everything, check the Recently Closed Windows and Recently Closed Tabs lists for other pages.
The unwanted window may be generated by an add-on. Try disabling ALL nonessential or unrecognized extensions on the Add-ons page. Either:
* Ctrl+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. Then, if in doubt, disable.
Usually a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Any improvement?
Here are some other things to check:
(1) user.js file that changes Firefox startup behavior and overrides your preferences. This article describes how to track that down and delete it if you have one: [[How to fix preferences that won't save]].
(2) Possible hijacked shortcut. Check the "target" of the desktop icon you use to start Firefox to see whether it lists the unwanted page. To do that:
right-click the icon > Properties > Shortcut tab
For 64-bit Windows 7, the Target should be no more and no less than this:
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe"
(3) Possible undisclosed bundle items. If you have installed any free software recently, check your Windows Control Panel, Uninstall a program for surprises. If you click the "Installed on" column head to group by date, it is easier to spot bundled junk. Remove everything suspicious or unrecognized.
(4) Supplemental clean up scans. Our support article lists tools other Firefox users have found helpful: [[Troubleshoot Firefox issues caused by malware]].
Hopefully that cures it.

I pressed Windows-M to minimize all screens, then Firefox 6.0.1 (Win XP VM) started to open large number ( 70 in a few seconds) of new Firefox windows (stopped only when I killed the Firefox process with Task Manager). Firefox had no focus at that time.

Windows XP 64-bits Virtual Machine, ServicePack 2, 4MB of RAM, dual processor running on a Windows 7 64-bits host machine, ServicePack 1, 8MB, 8-core processor.
I have worked with that for half a year, no particular issues.
I was working in other program in my VM (so Firefox had no focus) , then wanted to view my VM desktop, so I pressed Windows-M to minimize all windows in my VM. Exactly at that time Firefox 6.0 started to issue new empty Firefox windows, at a pace of about 4 or 5 per second. So I killed the firefox.exe process in my TaskManager to prevent my machine of running out of memory. Then I started Firefox again, without further issues so far.

I'm a Chrome user by choice. I use Firefox for two reasons only:
1) Speedbit video downloader
2) A second browser to handle secondary Google and Facebook sign-ins.
If I remove Speedbit, I lose 50% of my reason to use your browser at all.
Speedbit and Firefox worked together just fine before version 19.
PLEASE PROVIDE A PATCH. DON'T BLAME SPEEDBIT.
Thank you.

Each page I navigate to comes up as the google home page or a google error message.

Each time I try to navigate to a new page, firefox either takes me to google home page or gives me a google error message. I have removed the software and reloaded it. I have cleared the cache and the cookies.

Go to Settings-Safari and Clear History and Clear Cookies and Data.
Another thing you can try is to double-click the Home button. A row of recent Apps will line up along the bottom of the screen. Scroll across and find the Safari icon. Press on it for a couple of seconds until it starts to wiggle. A red minus sign will appear on each icon. Press on Safari's minus sign to remove it. This may clear its memory of the bad Google page.
If this does not help, try resetting (rebooting) the iPad. Hold both the Home and Sleep buttons for several seconds until the Apple logo appears. Ignore the "Slide to power off" arrow. The iPad will restart after a couple of minutes. Resetting this way will not hurt anything, and sometimes clears up mysterious problems.

Ince updating my firefox browser whenever i click on an internet link in an email it does not open on firefox although my mac switches to the firefox window as this is my default browser- what to do? Previously this has always worked without a hitch...

ince updating my firefox browser whenever i click on an internet link in an email it does not open on firefox athough my mac switches to the firefox window as i have this set to be my default browser- what should i do?

I have the same problem, and I also wondered if Google toolbar has anything to do with it. There GMAIL was set as the default mail application at first. I have removed that setting, but Firefox 4.0.1 continues to use GMAIL instead of Outlook which is my selection for mailto handling.
