Whenever I change my VPN (not Mozilla VPN) status, Firefox will refuse to connect for something like 30 seconds then times out, leaving me with a blank screen. I have wait until that interval has passed before I can retry, otherwise it will repeat the freeze. This happens whenever I turn my VPN on/off or switch to a different VPN server. It happens only with Firefox. Chrome and my email client have no problems whatsoever. I think it's some kind of DNS caching problem within Firefox as the problem doesn't happen if I visit a site that I hadn't visited very recently. There's immediate response if I do that. I have DNS over HTTPS and secure DNS turned off in the settings, so it can't be those.

Anyone else have this problem? I wish there was some way to clear Firefox's DNS cache other than having to go into about:networking

After restarting my computer last week, I suddenly couldn't reach ANY websites on my computer. I tried changing security settings. I tried deleting Firefox and reinstalling it. Still, to no avail.

I don't have any problem reaching websites via Firefox on my laptop or my mobile devices. I also have no issues with using Google Chrome or Bing.

For some reason, though, I'm suddenly having the same connectivity issue using Zoom, citing Firewall and Proxy issues (I'm a single, home user). I tried turning my security program off, and that didn't help. I also did a scan using the security software and it could find no malware.

I have tried restarting the computer, and powering off and restarting the router. No help.

I'm not sure why I'm suddenly getting this issue with my desktop. I have Dell ProSupport, and while they're trying, they haven't been able to nail anything down.

Any ideas why this would suddenly happen, and only to Firefox? (and, for some reason, the Zoom connectivity?)

I am suddenly getting pop-up windows from "Firefox Software Updater" as soon as I click the Firefox icon on my desktop (Windows 11) and laptop (Windows 10). The Firefox log in the pop-up is not in color, so I am immediately suspicious. The pop-up window did not happen on my laptop yesterday, but I got it on my desktop today, for the first time. I have answered "no" to the "do you want this app to make changes to this computer?". Is this legit from Mozilla? Usually, the browser updates automatically when I click the icon, saying I am now using the latest version of Firefox. Thank you.

Later version refuses to connect to my modem, and goes into security web mode. This modem uses HTTP/HTTPS for access, i.e., connects directly it's IP address, then the user enters a username and password. At that point, the the modem switches to HTTPS for control.

With this recent update, there is NO WAY to access the modem for any work, or upgrade the HTTPS certificate on the modem. This is a BUG.

What should happen is that if the web site will accept a HTTP connection, Firefox should NOT refuse connection or test for security issues UNTIL the user or the device switches to HTTPS.

As an aside, I've used Firefox on this Zywall modem for years until recently.

Firefox 120.0.1 Memory Leaks, Windows 11 & 10, not a new issue

Firefox uses too much memory, sometimes 20GB on a 32GB Windows machine. It's usually one or two threads which are hogging incredible amounts of memory. This time I had about 30 tabs open.

Today I tried Firefox about:memory "Minimize Memory Usage" several times, and it was largely ineffective.

I did a "create memory dump file" of one 5+GB bloated thread using task manager, but can't find a way to upload the compressed archive with this report for analysis. Finding a way to report this issue was quite a challenge. It seems most help avenues are now missing/moved, and other reports of this type of issue are "Archived".

I tried killing the 2 bloated Firefox threads and checked for tabs which might be missing or malfunctioning. Everything continued to run normally while more than 10GB of memory was returned to system use. Leaving these bloated threads overnight doesn't improve anything, in fact I can often get up and find my machine is completely out of memory because Firefox consumed it all. My smallest machines have 16GB RAM.

These memory issues aren't new. I've been reporting them off and on for more than a decade. They get better for a few months after reporting, then they get bad again in a few more months. The battle to get memory leaks fixed is continuous while Firefox springs more leaks.

I'd like to give you the memory image I generated so you'll at least have some real data to look at and analyze for this report.

The attached task manager snapshot image is a very minor example of this issue. The numbers keep increasing like there are one or more large memory leaks.

Hi, I am using Firefox vsn 120 for Linux Mint. I believe that I have the privacy and security set with the default settings.

However, Firefox seems to forget the information stored by websites, so that can't simply login.

Each. And. Every. Time. I have to go through the process of re-introducing myself to the security of the website provider who insists on sending me emails, SMS messages, etc. with codes to confirm who I am.

This applies, every time I use a site that requires a login (bank, BBC, Fidelity, eBay, Facebook....).

Once I have been approved on a site, then my login seems to work for a few days, up to a week and then off we go again with a new set of security codes. My settings do not delete cookies, and firefox is never closed, except if the PC needs a reboot, which is rare.

I would appreciate any help in settings that would allow me to use Firefox normally without having to enter security codes. Cheers, Mark

Hello,

I just got a new Macbook Air and I am trying to sync my bookmarks and preference etc., from my current Macbook Pro. I read the help articles and one thing I cannot find is a "Sync Now" option on the Air. It is not under the menu icon list. I signed out of the Pro and back in. The user and PW are the same on both laptops. Hoping you can help.

For the last two months since November 2023), log-in to the Wells Fargo online bank site no longer goes past the log-in page. If I use Edge log-in works fine. I use private browsing on Firefox, but I always have. I have Firefox password enabled, but I always decline to use it for online banking when it pops up (and it doesn't matter if I accept it, still no log-in on Firefox).

I don't want to use Edge but Firefox no longer is working on this task for me.

bold textWhy is Mozilla Firefox BLOCKING Kaspersky products, especially Kaspersky Password Manager? It has become an continous on-going problem with many,many people using Firefox which will definitely result in Firefox loosing many users.

Is this another USA bigoted anti Russian propaganda SETUP? Kaspersky is without question, the best protection software on the market. It just works, which is more than can be said about Mozilla Firefox.

Firefox has been my default browser for longer than I can remember. Over the years, I have maintained a significant bookmark file for work. I recently purchased a new computer, and my zero bookmarks from the new computer have replaced all of the bookmarks that I had in my old browser. This is a bookmark file that has successfully followed me through multiple computers and even my ios devices. And now it seems to be completely gone. I've looked at the places.sqlite files, and the largest one is 20MB and is in my current default profile, but it is dated today. That makes no sense because I do not have any bookmarks on this older computer, and my new computer doesn't have any either. The bookmarks have also been completely deleted from my iPad, but miraculously are still on my iPhone (evidently I had signed out of Firefox for iPhone at some point so they do exist somewhere.) The thought of trying to rebuild my bookmarks is nauseating. My only thought is to sign out of the browser on all devices, then sign back in and sync on the phone. Would that repopulate the main file with what's on my phone? Any other ideas?

Why is Firefox suddenly not remembering any of my logins or passwords? When I go into Preferences > Security, the box to "remember logins and passwords for websites" is checked. When I click on saved passwords they all are there. The do you want to save box is there if I have changed a login, or added a new web site. I am not in private browsing mode. The problem seems to happen every time I install the latest Firefox update, or Windows 10 Pro updates. Some of my apps want to know if I am using a new device.
