Diễn đàn hỗ trợ Firefox

on some sites, when I try to sign in I have entered my login information, but when I hit enter or submit for instance bigfishgames.com nothing happens. When I am on my Drs portal after I have entered pages of information and hit submit, again it does not get accepted. Soooo, I have to leave firefox and go to a different browser. Any help would be greatly appreciated, it is very frustrating when this happens. It is so frustrating that even though I have been on Firefox for many years I am thinking about using a different browser.

For some reason, I am locked out of signing in to Mozilla VPN. I have twice changed my password & recovery key, & then been returned to the app to login & it has failed to do so?

Just checking Facebook "download your information" and got this:

```

     {
       "timestamp": 1781017200,
       "label_values": [
         {
           "label": "Date",
           "value": "2026-06-09"
         },
         {
           "label": "Business or organization",
           "value": "Firefox",
           "description": "The business or organization that added you to a Custom Audience"
         }
       ]
     },

```

Is this actual Firefox passing my info to Meta, or some Meta scammer pretending to be Firefox?

On that date, I had Global Privacy Control turned on in Firefox.

I have recently discovered that Firefox is constantly sending data at around 3KBytes/S to a variety of Cloudflare servers.

What is the data that is being sent and why is this happening?

This has started to occur in one of the last updates to Firefox.

Currently running 151.0.4 (64-bit) on Windows

Does this constitute a privacy violation, what is the data that is being sent?

My Home page is a local HTML file featuring a CSS-based tabbed notebook holding links organized into various categories. When exiting FF, I always have this page as the active browser tab, so that on start-up it's still the active one in the event of multiple open browser tabs.

Until v151.0.4 (and still now with v152.0), if I exited FF with the active notebook tab (actually a styled radio button under the hood) in my CSS tabbed notebook something other than the first/leftmost tab, FF would restart with that being the active tab, but after a few seconds of CPU activity as the browser initialized the active notebook tab would switch to the first/leftmost one. (In my HTML I also have <input type="radio" name="tabs" checked> specified for this first/leftmost instance.)

Since the update, however, it remains stuck on the one from the last browser session as first displayed. I suppose I can live with this, but I do wonder what accounts for the change in behavior. If it's by design, where is it documented? If not ... maybe it calls for a bug report.

I'm a Chinese firefox user, so the following descriptions are translated and may not be so accurate. And the attached image is also Chinese, if necessary please use a translation app or somewhat to see it. I have only one default profile in my Firefox account, and I have stored a large number of passwords and bookmarks in this default profile. For certain reasons, I signed out of this profile while retaining the local data such as passwords—meaning that, apart from not being logged in, my browser state remains exactly the same as before. Now I wish to sign back in to enable synchronization. I can see a "Sync and Save Data" button prompting me to log in. After clicking this button, I am asked to enter my username and password, but then I receive a message stating that I have reached the account limit for this profile, and that this profile was previously synced to another account. This is absurd, as I do not have another account, nor have I ever synced this profile to any so-called other account. As a result, I am unable to sign in on this current profile.

I have firefox on another PC with wallpaper I wish to install on my current firefox. I have identified its name = "Abstract". The wallpaper image url is https://firefox-settings-attachments.cdn.mozilla.net/main-workspace/newtab-wallpapers-v2/a205885e-194a-41f9-ae47-e7da66a74041.avif. The image is a205885e-194a-41f9-ae47-e7da66a74041.avif The current firefox version I wish to install this wallpaper on is 151.0.4 (64-bit) Please provide navigation instructions on firefox to install. I am uploading the image of this wallpaper for you easy reference. Thanks

Hello,

Since this morning, I haven't been able to access Bsky on my laptop because of a supposed HSTS risk, which means I can't add an exception to visit it. I use Firefox on my Android and going to the mobile version of the website lets me in no problem, so I assume there's an issue with my laptop.

I'd usually wait a few days and let it solve itself but just in case it's something on my end, I'd like to solve it! I'm on 151.0.4 (64-bit), don't use a VPN or an anti-virus, I have a couple of privacy add-ons but they've been here forever and they've never caused a fuss. I can post a screenshot of the error code and the certificate it sends me if it's any help.

I'd appreciate any pointers! Thanks!

recent firefox update can no longer copy and paste when creating a blog post in Squarespace, I have been using squarespace for around 15 years for my websites and I have never seen this issue, Firefox 15.1 installed and all of a sudden when trying to create a blog post in Squarespace, when I right click a text box pop up and it no longer says paste so I can no longer copy and paste text - this is more than a little annoying, you will not be surprised to know that I am now using Chrome to create my posts, there is no issue in chrome. I am a firefox geek! how can i solve this problem, I just did another update from Firefox, the issue remains I have been using computers for 40 year so I am not a novice but software glitches, I am lost

Hi there!

Firefox did an update today and the firefox VPN option disappeared, there is no option in settings or the menu for the VPN any longer.

Thank you!

i haven't used Firefox for a while but when i tried to import my bookmarks from Brave, they were imported but i cannot access them. i would have believed that Firefox would have either given me a 2nd listing or merged them into the ones i already have. am i to believe that this cannot be done? or am i overthinking this import thing?

Dear Mozilla Firefox Support Team,

I hope this message finds you well. I am reaching out to seek guidance on how to disable settings pop-ups in Firefox, as I find them to be somewhat intrusive to my browsing experience.

While I appreciate the various features and options Firefox provides, I prefer to have a more streamlined experience without the frequent interruptions caused by these pop-ups. They can be distracting and make it difficult for me to focus on the content I am viewing.

Could you please provide me with detailed instructions on how to manage or disable these specific pop-ups? If there are any settings or configuration changes I should be aware of, I would be grateful for your assistance in helping me achieve a more unobtrusive browsing environment.

Thank you for your attention to this matter. I look forward to your prompt response. Dear Mozilla Firefox Support Team,

Firefox promised us an gen ai kill switch. But theres this new ai summary feature that is not automatically disabled when i press the kill switch. Could you fix this, so that when i press the disable ai button all gen ai features are disabled! Even the ai summaries feature. Could you also not hide or try to sneak in any more ai features! Nobody needs ai features, it's actively making us all dumber. Thank you.

Firefox will randomly require an admin to install the latest update and then go 10 or so updates without any admin access needed.

Work device, all users are non admin making this extremely tedious to update a browser that brings a new update almost every 3-5 days.

On top of that, I elevated to admin and went to the help > About section and pressed Restart to Update Firefox and entered admin creds and still its refusing to update. Just re-opens on 151.0.4.

On the previous version it did the same thing. I completely wiped my firefox from the system, removed all registry and file settings, rebooted, and did a fresh install.

now on 152.0 its doing the same thing again.
