Firefox Community Forum

My version is the most recent, 152.0.6.

After a few minutes, text searches in the address bar unpredictably stop working. This might happen right away, or it may take a while. The result is always Secure Connection Failed The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Here are the problems that I encounter literally every day: Randomly unable to access GMail: account selection entry screen does not respond, or drop-down account selection when logged on does not respond. Randomly unable to access URLs embedded in emails. Browser locks up unpredictably. Videos in Facebook randomly fail to render: the audio plays, but the bottom half of screen completely blanks. Randomly unable to access websites in general: "secure connection failed". Randomly refuses to search for terms entered in the address bar, with "secure connection failed". Widgets on web pages randomly fail to respond.

I'm using the VPN that comes with my AV package, and turning it off makes everything work again. However, I'm certainly not going to turn off part of my web protection (which I am paying for) in order to get Firefox to perform basic browser capabilities. TBH, all of this started when Firefox started aggressively promoting their own VPN, so it's quite tempting to put two and two together.

I would prefer not to resort to Edge or Chrome, but at this point I don't see an alternative as they do not have these problems and Firefox has basically become unusable.

Je ne peux plus accéder à Facebook sur l'ordinateur. Attente éternelle de la prise en compte des mes codes. Alors que j'y accède normalement sur mon téléphone portable et sur ma tablette. Je suis protégé par Bitdefender. Quid ? Merci :-)

Since your last upgrade, I have been able to get into any sites using CloudFlare security. Prior to that I had no problems at all. I have tried closing extensions and or clearing cookies. I especially want access to my banking account. How can I disable whatever was added to effect CloudFlare? CloudFlare either continues to cycle, or gives an error message.

I know the sites are secure (unless something is happening that I don't know about). I just want to get onto them, especially the Christmas site. Is it to do with Bitdefender?? I hope someone can help as the letter I want to write is getting time sensitive.

I wasn't quite sure what topic to put my question in, but I have the following problem: I recently went into my browser settings and saw this(I attached screenshot). what does this mean? my browser shouldn't be managed by any organization, because it's my personal computer... I thought it might be because of the vpn, but I already uninstalled vpn, but that didn't help.

I would like to know whether this is a normal process that happens when using firefox browser or has my version of the app been compromised? Or should I allow this to be accessed?

Firefox is not allowing me to reach links to medical portal websites to set up accounts saying they can't reach the site and perhaps a firewall is blocking it. I have other accounts on this same portal... HELP please.

I got the new FF update this morning and noticed shortly after when i got back online a bd_config.cfg file popped up onto my desktop windows 10. I deleted it not thinking anything about it and when back online again and it popped up again in fact everytime i did this it popped up no matter what i did and went online.

It has something to do with BitDefender i figured out uninstalled bit defender re installed it no luck

Refreshed\Reset Firefox with no luck either.

One specific cache entry always contains a trojan virus everytime I run an anti virus check. I can't say where this cache comes from as it appears even if I don't open a single new website. I delete it but it appears everytime I use the Browser again, even multiple times during one session. It is always the same entry code. Is there a way to block a specific cache entry or at least to discern where it originates?

Near the top of the Firefox page is displayed:

"The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can caused this problem".

How do I resolve this problem?

I'm using Windows 10 on a PC. Norton Security app is preventing web browsing by Firefox. The message I get is: "We prevented your connection to ful.hartonly.com because it is a dangerous webpage. Threat category: URL:Blacklist" I can still web browse using Google Chrome without any problem. What is ful.hartonly.com and how do I clear it?

Hello, I'm an avid user and supporter of Mozilla Firefox. But I installed AVAST as an additional protection tool...and I have just subscribed today to Avast Antitrack to avoid being tracked and hacked. But, to enable AntiTrack, I'm now prompted to add it to Firefox !? Before any action, I'd like to know that this will be efficient and safe : can you confirm that this is compatible with Firefox's proper operation? Thank you, P.Huens.

After instalation Eset Smart Security 18.2.18.0 with full security browsers my Firefox is run only in read-only mode. If I will be disable option Security browser and run Firefox that's working. Next I will be enable option Security browser then Firefox starts with green frame. After close Firefox and next run then starts read-only mode. Eset Team is not fair play becouse resolving problem only disable option Security browser. So why is there an option that prevents Firefox from launching? All my portable browsers without Eset Security working without any kind of problems, for example Tor, Opera.

How to get rid of ImportEnterpriseRoots, so I can control my own computer & update Firefox? (Update options are not shown under Settings- General tab any longer for me due to the message showing "Your browser is being managed by your organization"--ImportEnterpriseRoots"? I am the only user on my computer & definitively not part of an "Organization". I found some help online that was way too technical for me. Thanks!

Hello!

I use a VPN when I access the web and I recently updated my OS (Mac OS Tahoe). I updated Firefox and now DNS over HTTPS (DoH) is enabled in Firefox. When I have my VPN enabled, I cannot access the web, there is some problem with DNS resolution. I have changed my Firefox DoH settings to Standard (I have also used Strict) and have typically been unable to resolve web URLs correctly. There have been a few times that I have been able to use 'Standard' DoH strictness / settings and also use the VPN successfully at the same time, but typically when I have the VPN enabled Firefox cannot access whichever 'mozilla.cloudflare' address it is attempting to use for DNS resolution.

The VPN vendor suggested always using the VPN's DNS resolver. I have done this and I still have the same problem. What should I do to ensure that I have secure DNS and can successfully use a VPN?

Thank you.
