I am using Firefox Beta 156, Version 4 on Windows 11 Professional, 25H2. I have an odd error, "Look up over IPV6 failed lookup." It occurs on two different VPN's, Proton Free, and Windscribe Professional. Any assistance, or insight would be highly appreciated. Thank you kindly.

I routinely check out several local news outlets' websites and for the last 2-3 weeks, since a Firefox update (using FF 156.0.1 (64-bit) on Win11, v25H2, Build 26200.9550) I keep getting a Norton popup box saying "we prevented your connection to <x> because it is a malicious website", where 'X' is either littlestastronaut.com, or something like planted.com (screenshots of Norton popup windows doesn't work). This doesn't happen with any of the other couple dozen websites I visit, just 2 out of the maybe 5 or 6 different news websites I look at. Odd thing is I look up either of these two 'dangerous' websites and they either don't exist or they are some school related website. That popup comes after I have to select either "continue without ads" or go to the FF address bar and disable the ad-blocking for that site, so I'm thinking that there's maybe something in FF that is causing this? It happens on both of these sites whether I check "continue without ads" or disable the FF ad-blocker which doesn't make sense that that 'malicious site' is contained within an ad on the news site because on one I don't disable ads so it shouldn't even come through but still Norton catches it??? Yes, A-I will one day rule the world....ya-right.

every time I do a search this comes up: with captcha;About this page Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen? I have already uninstalled and did a refresh but nothing works

I would like to know what are the best Antivirus Protection to use with Firefox. Previous information is from 2011 and I would like to get more current information. Thank you

Like many, I have Windows 10 and cannot upgrade to Windows 11 without purchasing a new computer. I don't want the upgrade as my desktop computing needs are simple -- checking email and occasional online research. I am looking at 0patch as a solution to Microsoft discontinuing support for Windows 10 and want to know if Firefox will operate compatibly with 0patch providing security patches instead of Microsoft.

I'm not a technical person, so please keep replies simple. At 80 it's tough to keep up with all the changes! Thanks.

I am trying to set up a vpn using Proton as a Firefox add-in but Firefox won't let me use it, saying it has invalid credentials. I can't contact Proton because if I enable it as an add-in to Firefox, I can't use my browser. Do you know of any other vpn networks that work securely with Firefox?

My bookmarks, history and passwords have disappeared. I looked at the articles, refreshed firefox, have restarted firefox and my computer multiple times but cannot retrieve them.

This is the message when I start firefox

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.

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 following message while trying to access this website https://nubecomun.yanapak.org/ The connection has timed out:

The server at nubecomun.yanapak.org is taking too long to respond.

   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.

How can I allow Firefox to access the site?

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.

I have a flag that says my Browser is managed by the Organization. I cant find any help on HOW to fix it, I only find pages telling me things that make no sense to me as a sole user. None of my other computer have this flag on the settings page.

How do I remove this or changes this setting, since it makes me feel like some outside agency has tried to control the browser

WHY DO I KEEP GETTING THIS ERROR???

"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 never got this before but now i get this every week. restarting my computer does not fix the problem. this sucks! the article to fix this are way too complicated. how do I fix this? I use Ccleaner and reboot, but that does nit fix the issue either. HELP!

8 out of 10 times that i try to connect to the following site:

https://www.tax.ny.gov/online/

I get the following error message:

Now and then, I'm able to log in successfully. lately though, I'm having trouble logging in using Firefox browser.

This is becoming very frustrating. What could be the issue? What do i need to do to resolve the problem?

Is Webroot a part of Mozilla/Firefox? When Firefox recently updated it began to ask for a Webroot access key and it takes me to this page. I have never signed up for Webroot before.

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.

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?
