Firefox Community Forum

I continually get error messages for webpages. I turn off my VPN, clear my history. Not sure what else I need to do. Last one was the webpage for Lindt Chocolate. Come on. Why am I getting error messages for this? I have been on this page before. There are other places also, like Macys. Getting fed up with Firefox.

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.

I was in contact with Bitdefender Support and they suggested the following:

If Facebook still won't open, open Bitdefender and:
  - Go to Protection > Online Threat Prevention > Settings.
  - Turn OFF "Encrypted Web Scan" temporarily.
  - Now reload Facebook in Firefox.

Afterwards, I also had to click on "Messenger" to get all my contacts.

This is temporary since before FF 150, Bitdefender ran with "Encrypted Web Scan", and I had no problem in loading Facebook. So something that changed in FF 150 conflicts with Bitdefender's "Encrypted Web Scan".

Ich habe die Firefox-Einstellungen von einem alten Windows10 Rechner auf den neuen Windows11 PC mit den Profildateien übertragen, hat gut geklappt.. Jetzt hatte ich die Meldung erhalten " der Treiber cpuz419_x64.sys konnte nicht installiert werden wegen möglicher Virus-Gefährdung", als Abhilfe wurde angeboten die Ker-Sicherung auszuschlaten. Das habe ich mir nicht getraut. Als weitere Info erschien eine Seite, auf der "Windows10" unterstrichen war. Könnte das alte Profil dem Rechner vorgaukeln, dass ich Windows 10 nutze?bold text

I installed update 149 and since then, the VPN (NORDVPN) often will not start up and I have to restart the computer. If this cannot be fixed, I would like to go back to the previous version which gave me no trouble. thanks Brian

I've started getting Virus/Trogen warnings from McAfee popping up every few seconds on Firefox. There was a McAfee file on my Acer desktop but Not installed. Windows Defender and Malwarebytes do not detect a Virus or Trogen. Is this a SCAM by McAfee to get money from me? I cannot delete the McAfee install file as it says it is in use!

My anitvirus software is blocking a website that I use. Its legitimate. How can I unblock it?

An error occurred during a connection to radoneyepro.com. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Hello. I'd wriitten a few days ago about being blocked from firemountaingems.com I got help from Issis B. and was able to browse the site by turning off the VPN temporarily. Today, I am again blocked even with the temporary turn off of the VPN.

Is there a way you can show me easily step by step, how to exclude certain sites from the VPN permanently.

Thank you in adavance.

Malwarebytes is picking up and blocking an outbound connection request from Firefox - www.highperformance.com. Anyone else experiencing this?

Every new version of firefox just gets slower and slower. Now with version 152.4, I try to load a website, it just continuously tries to load, doesn't even if load the page just has those 3 dots to indicate it is loading. Nothing ever loads

I am starting to think switching from firefox is necessary at this point because no other browser has this issue like firefox. No other browser consumes a ridiculous amount of memory like firefox does.

I did adjustments to my anti-virus as recommended, did the settings changes on firefox to speed it up as recommended, still same issue.

When you guys create a new update, please focus on speed over security and ensure it loads faster. I am likely going to revert back to an older update or switch browsers, because I don't care about security so much as actually loading a website.

hello team, I currently locate in China. days ago i have tried a vpn called "Veee". since then i could not log in many websites. i have asked Veee team but they say they dont know. it really sucks. i also asked AI tool but none of the method works. i think the vpn has changed some settings of my Firfox. because i can actually log in those websites with Edge. but i only want to use firefox. the errors either "cant connect" or something like refusing my access. please help. i love you guys.
