Here's the message I get 'intermittently when I open Firefox, which is my default browser:

Fix "The bookmarks and history system will not be functional" error message

The "fix it" page doesn't suggest any possible security program obstacles. Can you help me find the culprit?

bold textI downloaded fire fox but don't see it listed with my other browsers, why? i downloaded fire fox but it's not listed among my browsers, why?

On last Firefox update my Password manager was blanked out. I had no username/passwords in my Password Manager although I had previously had over 100. I managed to recover it by logging in to my Mozilla account but now have access to over 7000 of other peoples usernames and passwords on my password manager. You seem to have a major data breech or is this a quirk I don't understand? These other names/passwords show up when I try to log into certain sites, such as Schwab for example, and I have to pick mine out of a host of others to fill in the login info. What is going on?

when visiting websites using my vpn firefox blocks my entry. I have to disconnect my vpn to allow entry to sites. ive tries numerous fixes and nothing works its frustrating.

I am on a new PC with Windows 11, using 4 monitors. I keep trying to figure out what is making my mouse and sometimes the keyboard behave sluggish (freezes for a moment). I have takes all suggestions that AI has suggested but it is still happening. Do you have any thing for me to try? It appears to be only when Firefox is running.

I use Firefox to manage an online course. For some parts, I want to zoom in to see detailed diagrams etc. In other parts, I want to see at a glance a simple list of submissions. So I have 2 windows (with their relevant tabs) open. But when I zoom into the first, the other window zooms in, so I lose most of the listing. How do I set the zoom differently in the two windows?

Firefox continually shows pop ups for a passkey and it will not let me sign into a webpage without it. I have seen a way to disable the pop ups online, but I am 84 and not techy. If I cannot stop them, I will stop using Firefox and Use

Hello! Please report this bug to the developers. When I first launch Firefox after turning on my computer, the window title bar and buttons in the upper right corner (like "Minimize," "Minimize to Window," and "Close") sometimes disappear. If I minimize the browser via the bottom taskbar and then restore it, these buttons and the title bar appear. I'm using Windows 10 x64, with a screen resolution of 2560x1440 (scaled to 125%, but I don't think this has anything to do with the scale or resolution, as other browsers (Opera, Edge) don't have these title bar issues).

See screenshots at the links: https://imgur.com/a/Hbc9yvE (There are two screenshots: 1 - with the window title and buttons (as it should be), 2 - when the window title and buttons disappear)

I've noticed that if I let Windows sit for a while after turning on the PC (2-3 minutes) and then launch Firefox, the problem with the disappearing title bar and buttons seems to disappear. Apparently, Firefox doesn't have time to load properly after Windows loads, and if I launch Firefox almost immediately after Windows loads, the problem described above occurs. And when the OS sits for 2-3 minutes, Firefox apparently loads all its services and processes normally and then works normally, without this error. Firefox ver.: 150.0.3.

This bug was also discussed on the forum by some other users, and they are also experiencing this bug: https://forum.mozilla-russia.org/viewtopic.php?pid=818805

I like the Firefox home page. Except for one small issue. That is Shortcuts. If checked it defaults to "sites you save or visit". It is a pain in the A$$ to clear away visited sites. I would prefer to have the option to keep saved sites and not keep visited sites. Can Firefox please seperate saved and visited. In another words make it an option to keep visited sites.

How can I upgrade to windows 11 or is it to late? Can't connect to internet. Everything else is house is fine. Says Firefox disconnected. I can't sign in on laptop, says windows 10 support expired 10/2025?

Hello. When I opened my browser, you forcefully opened a tab about VPN and how to install this. However I cannot find the mentioned "get started" button.
