Firefox will no longer open Google without a "This Connection is Untrusted" error, and no option to get a temporary certificate is available.

This problem popped up for the first time a few months ago. but I was able to work around it by by clicking on "I understand the risks" on the "This Connection Is Untrusted" warning page, and then by adding a security exception. That fix would work for random lengths of time... sometimes for days, sometimes for minutes. Now, after updating to the latest version of Firefox, I get the same security warning but the option to click "I Understand the Risks" is gone. I get this error message on the technical details page: (Error code: sec_error_unknown_issuer

I have done everything listed here many, many times: https://support.mozilla.org/en-US/kb/connection-untrusted-error-message I mean everything. Delete cert.db, start in safe mode, empty cache, delete and reinstall.... Nothing works.

Your help would be greatly appreciated!

Firefox has begun opening very [very!] slowly, as well as crashing and freezing during use. This is happening on all of my three machines, two running Win 7 and one Win 8. I have tried refreshing and disabling hardware acceleration, but to no avail. Now it seems to freeze on opening and takes a minute or two even to become responsive, if at all. When I look at Task Manager during a freeze I see the Firefox process is using 35-50% of memory [i have 8GB, 12GB and 16GB] and up to 50% of processsor resources. All has been fine until the last couple of weeks. As an adjunct, in the last month I have noticed an almost permanent error message on the status bar - "Sync encountered an error while synchronising: Unknown error. Sync will automatically retry this action."

I cannot delete the Unsorted Bookmarks folder (delete is grayed out, as is Cut) and it has literally thousands of entries. I rarely if ever use the star so they must be being added automatically. Most of the entries are "Real Player Home Page." I think this huge number of (useless to me) bookmarks is affecting the Sync function as it keeps telling me it has encountered an error.

Until recently I was using Xmarks but that, too, has stopped functioning.

I am at a loss as to what to do to get rid of all those bookmarks under the UB folder.

Hello, I've installed various games onto my computer such as Garry's Mod, and several other 3D type games that work perfectly fine without Firefox on, no crashes no problems. Several of my games (exception is minecraft), whenever I have firefox just up and running, it will just crash my computer. Black screen instantly, no warnings, just instantly switches everything off. I've scanned several times, I have no viruses and the games work normally without firefox.

But what could firefox be doing to cause my computer to crash with them on? Is there a way to fix it?

Firefox was too large for my monitor screen. So, I typed about:config in the address bar. Then I went to layout.css.devPixelsPerPx. I then made the terrible mistake of putting 2.0 in the box and the text went so small I can't do a thing in Firefox. I can't see anything on the screen even with a magnify glass. I am using my laptop right now. The problem is on my desktop. Vista Home premium 32 bit. I just downloaded Firefox yesterday. I did have Chrome on. They stopped supporting Vista so I thought I would use Mozilla. Remember, I can't see anything on the screen to be able to fix it. Help ,someone please!!

I had to restore my operating system. I was able to recover places.sqlite to restore bookmarks (good!). I was able to find a key3.db (dated July 2013) that file won't be complete or up to date, but at least it puts me somewhere ahead.

I read that I need a signon3.txt file to go with the key3. I don't have one. I did find a signons.sqlite file dated Sept 2014. I moved both these files to my profiles folder but I don't get my old passwords back.

Is it possible for me to use the old key3? Do the key3 and signons have to be dated the same? Is there a way to recreate the signons.txt?

I do have the master password.

Thanks for help.

Firefox 39 (and 38 before update) suddenly refuses to load one website: after input of username and password, it refuses to go further on Chase.com. There is no error message. It is simply a completely blank page. FF does not even appear to attempt loading the page as there is on loading indicator.

This is on two Macs: iMac with Mac OS 10.9.5 and Macbook Pro OS 10.10.4. Current FF version: 39 (but started with v.38).

Have done all the troubleshooting from FF website including a complete reset, restart, checking Network settings, and every other suggestion under "some websites do not load".

Have spent an hour with Chase support including (again) clearing all cache, cookies, history, reset Firefox, and attempting to login with temporary identification codes; sometimes I get to the next page to enter that code, but the following page is - again - completely blank or, I am not even able to enter the code as I wind up with a completely blank page. No error message at all.

There is no malware evident. There is no AV software installed (it's a Mac!). There is no problem with any other website, including other financial sites requiring logins. And, there is no problem loading that website with Safari, so it does appear to be an FF problem.

I have recently started encountering a problem accessing Google news links from my browsers (Firefox 39.0) and IE11 that involve a particular website – telegraph.co.uk. I keep getting the message Server Not Found. The long initial browser links to all other sites (Guardian, Reuters, FT, Daily Mail etc.etc) all resolve very quickly and show the required page….but not those to telegraph.co.uk. I can, albeit very slowly, successfully connect to telegraph.co.uk links via anonymox add-on proxy server – not ideal. We have2 other laptops, another pc, 2 ipads and 4 iphones in the household and none of them have my issue. My PC runs Windows 7 Home Premium , running Norton Internet Security (22.5.0.124). I regularly run Norton Live updates and do full scans daily. I also run CCleaner daily and regularly perform Malwarebytes and Spybot scans (with browser immunisation updated). I recently updated to this version of Norton Internet Security from previous version and this may be part of the problem although another pc and laptop also updated to same version and do not experience my problem. No evidence, that I can see, of telegraph.co.uk being “blocked”.

I have tried various “fixes”, unsuccessfuly, as follows: 1) We upgraded to fibre yesterday from ADSL and had to move to new router. I had hoped that this would fix my problem, but no. Re-set new router as well, but didn’t fix. 2) In Firefox Options, Advanced, Network I have tried:

   a.	Clearing cached web content
   b.	Clearing Offline web content and data
   c.	Also tried Clear history, recent history, everything
   d.	Connection settings were same as other pc: Use system proxy settings. I did try auto detect option but this did not fix. Have,    for now, switched back to Use system proxy settings.
   e.	Tried Firefox reset, to no avail
   f.	Tried running Firefox in Safe mode with add-ons disabled, but did not resolve problem.

A fix to resolve this very frustrating issue would be gratefully appreciated. Many thanks in advance.

I hose sat for a friend a while back. I left my PC running so room-mate could use it. Upon returning I could not access my chosen search engine (duckduckgo), I get this as the effort

"Firefox can't establish a connection to the server at duckduckgo.com.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer's network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."

In fact I cannot access ANY search engine....... However it works on my tablet so I know it still exists and I grilled my room-mate who denies using the pc or downloading anything..... (he is fairly pc ignorant so I kinda believe him).

So what settings could have suddenly come into place that block me from my chosen search engine? (FTR I cannot access search engines in IE either and I HATE IE so having to check there made me feel unclean). (I also checked with the anti virus and cannot see that it is blocking me but Kaspersky was shut down and still no search engines so I do not believe it is the issue).

I have tried for weeks to get access to my search engine and am so stumped I now go to you.
