Each morning, when I first cold boot my computer, the moment I open my Firefox browser, I receive numerous (10+) identical error messages from Bitdefender:

Suspicious connection blocked: Feature: Online Threat Prevention

firefox.exe attempted to establish a connection relying on an unmatching security certificate to content-signature-2.cdn.mozilla.net. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one.

Question: Is this ACTUALLY coming from Firefox? If so, please match your security certificates! If that's impossible due to a technical issue, then please email me your confirmation so that I can add an exception to Bitdefender.

Question: If it's not coming from Firefox, please email me, letting me know what additional system information you require so that we can get to the bottom of who/what is masquerading as Firefox while attempting to establish an unauthorized Internet connection from my computer.

HP Envy laptop, Windows 10 OS, latest update.

This has been occurring for several months.

Thank you for your time.

I want to completely disable the 'restore previous session' option.

I want to start a new session with my preset home pages 100% of the time.

Having Firefox display a page 'unable to restore previous session' with the options of 'display previous' pages and 'start new session' is inconvenient at best. I do not want to see that page, I just want Firefox to automatically start a new session every time I open it.

In the Tools menu settings tab, the 'Restore previous session' checkbox is not checked.

Logging on to my bank web site is no longer possible with Firefox. It used to be, so I assume the bank's computer security protocols have changed. However, I can log on with the Microsoft Explorer browser - works every time! Moreover, in the past, when I could still log on with Firefox, I could never "register my device" for the bank site; it always gave me an error message. With the Explorer browser, I can register my device, with no error messages. I have tried all the suggestions in the Firefox help section: erased remembered history, erased all history, erased all cookies, erased cookie profile files. Nothing works.

I always used Bing as my homepage. Firefox will not allow me to change my home page to something outside your defaults. I have tried your instructions (I already knew how to do it as I have used Firefox for AGES). None of those work. It hasn't worked for a number of releases. I want to have the home page I want. There is no "saving" the home page anymore. And just changing and following instructions (even the drag and drop) had NO effect. If it close Firefox and reopen it, I am back to the defaults. I am kind of getting to the point that if I cannot save my settings anymore I just think I finally need to switch browsers to one that does.

According to FAQ of Caching Mechanism (mozilla.org), it is by design to cache “documents specifically marked for "not caching" through-- "Pragma: no-cache" or a "Cache-control:" directive specified as an HTTP response header” in memory to improve performance. So, it is possible for you to view sensitive information from the Firefox memory cache after you log out an web application and keep Firefox open.

I am constantly unable to access websites. My data seems to clog up. I'm in my 70's and have no patience or training for sifting though numerous fixes and possible solutions. I've done my best with no improvement. My husband is having the same issues on his computer. All my previous efforts erase my sign ins and require me to constantly enter new sign in information for my common websites. I can use Safari and Chrome without these issues so unless I get some form of personalized help that doesn't require a great deal of technological skill, I'm leaving this browser greatly disappointed in the lack of support.

Good afternoon!

We need to add a "Saved Password Exception" to Firefox on several remote computers on our network (Non-Domain). We do not want to block the saving of all passwords, but want to specify a few websites to never ask or prompt to save.

I was hoping I could do this with Mozilla.cfg or Policies.json, and distribute it over the network to each PC. All I have found is a way of blocking all site password save-prompts with "signon.rememberSignons" in the Mozilla.cfg.

Any suggestions on how to set exceptions for specific sites with either using the Mozilla.cfg or Policies.json? Otherwise I may need to edit the firefox configuration manyally on each PC.

Suggestions?

Thanks everyone!

The log in to a website previously worked on Firefox for several years. When I tried this week and hit sign in, NOTHING happened - no wrong password, no error message, nothing. I called their customer support. They passed me around for a while and decided that I had to reset my password. The reset link went to Firefox and nothing happened. I decided to try on Microsoft Edge, and the sign in worked with my original unchanged password. Anything I can do to make the website happy on Firefox? Thanks for your help.

Hello. Starting yesterday, Firefox has stopped playing audio from every website and even local files. Yes, I read this article and no, the sound is not being muted instead the sound just refuses to play. In the screenshot, it shows that the "play" "mute" and speed option are greyed out. Also, I tried using safe mode and audio still wouldn't play. What should I do?

Good afternoon, We have a large quantity of PC's that we need to add a Pop-Up exception to for Firefox.

Is there a way to add this desired website pop-up exception via a script remotely? I know where to go to manually add a Pop-Up exception (Settings/Privacy & security/Allowed Website Pop-Up's). But is there a way to script this? Can this even be locked with a PrefLock line in a Mozilla.cfg file? I did a little digging and did not see anything. That would be ideal.

Any suggestions are greatly appreciated!

Please note that the remote machines are NOT a part of a domain. But I have complete connectivity to them as an administrator on the same network.
