Bonjour. Depuis longtemps j'utilise Firefox Portable dand un bac à sable(SandBoxie-Plus). Depuis la dernière mise à jour Firefox plante, affiche incomplétement ou pas du tout la page. Je signale que sans le bac à sable Firefox fonctionne normalement. Actuellement je suis sur "WATERFOX" portable (version mai 2025) qui a l'air de fonctionner normalement.

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.

Hello,

we are observing big issues with mozilla firefox.

Few weeks ago it was impossible to use amazon with it.

Amazon support recommended us to not use the anti virus anymore, which was very strange. but it did not help.

After I add the antivirus addon to firefox it started to work. Unfortunatelly just for few weeks.

Actually we receive the following error and cannot browse or do anything Fehlercode: PR_CONNECT_RESET_ERROR

We have tried follwoing without success: - clearing cache - using problem investigation of firefox below button "help" - deinstalling and installing - installing the beta version

already after installation of firefox where normally terms and conditions to confirms shall appear we get the failure Fehlercode: PR_CONNECT_RESET_ERROR nd the content cannot be downloaded.

Hence Amazon does not work below google neighter and firefox is the only way o use amazon, we will appreciate your help.

Looking forward for your help

Lost all of my bookmarks. Error message reads: "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 cause this problem." I have been a Firefox user for years and years. I am having to leave because I cannot resolve this new issue. Can you help?

It can take many closing clicks to get rid of this warning and comes back again after a short while. What should I do? Tried searching with Malwarebytes itself and found no problems. Web search the same.

Malwarebytes Website blocked due to malvertising If you don't want to block .................................. IP Address: 108.62.60.42 port: 443 type: Outbound file: c:\Program Files\Mozilla Firefox\firefox.exe

When I open a new tab and enter any website name I cannot connect to any site and this has only just started The message I get reads cannot connect to server at gb.search.yahoo.com

I use Bitdefender as antivirus program. When I start up Firefox the antivirus program blocks the start up because it says Firefox is trying to access a program (sync.contextualadv.com) which does not have same authentification as the target. It gives me choice to accept this as an exception if I want. I don't understand the details but I don't want to allow this to proceed until I'm sure it is safe. I'm on an HP computer running Windows 11. I use firefox on another laptop running Windows 10 and have not had this problem.

I'm receiving this message 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 cause this problem.

Over the past 2 versions, I am having issues accessing a Linux Webmin (port 10000) site while using a VPN. I have no issue accessing this site when not over the VPN (on site) and I have no issue accessing the site while over VPN using another browser. Very strange issue.

All of a sudden when i sign in to Amazon I get this box: Windows Security: Please sign in to amazon .com: This request comes from Firefox.........: Never asked for it how do I turn it OFF?? I have no2FA in either Amazon or Firefox but all of a sudden i need to enter a Security Code.

Every time I used Firefox, my preferred browser, I get the following message -

"Software is Preventing Firefox From Safely Connecting to This Site

nordvpn.com is most likely a safe site, but a secure connection could not be established. This issue is caused by NordVPN S.A. -ThreatProtection, which is either software on your computer or your network."

- and then prevents me from any browsing. Why does this happen? 

How do I stop/prevent it in the future? Or do I just delete NordVPN and cancel my subscription?

Hello, Iam using Bitdefender Secure Pass as passwordmanager, but since one or two weeks I have problems with the functionality on the laptop. I just can't open it. It is popping up and closing down immediately. Autofill in is not working as well. This is only when I use firefox, in chrome it is working. And on my mobile it is also working in firefox. I deinstalled and reinstalled the add on in firefox already. Afterwards it worked for a short time, but now it is the same again. Does somebody have experience with Bitdefender and an idea what I could do? Thank you in advance. Sabine

Every time I open Firefox, Avast alerts me about a malicious website. It's always fyabyq.com. It only happens when I first open Firefox. Opening a new window or opening a private browser does not trigger it. I've cleared all cookies, performed a refresh, reinstalled Firefox, checked all my notifications for fyabyq.com, and tried using another browser. Firefox is the only one that gives me the alert. My best guess is it's a homepage add or news article causing it. Anyone know how to fix this?
