I get three grey boxes at the top right of the Firefox start-up page. See the attached image. They dissappear if I search and enter another web page. The only way I can get rid of them is to reset Firefox. They return within 24 hours.

What are they and how can I get rid of them?

Hi everyone.

Basically when the browser is (I think) idle while watching YouTube, FF is constantly backing up (the timestamp in the backup file name keeps getting updated). From the settings page I thought it once every 24 hours. I noticed from higher than normal CPU usage impacting FF and the Windows search indexer. Which reverted to normal once I disabled the backup.

I checked the about config:

• browser.backup.scheduled.minimum-time-between-backups-seconds

Is set to 24 hours (86400 seconds)

But I also noticed:

• browser.backup.scheduled.idle-threshold-seconds

Is set to 15 seconds(!). Is that what I think it is? Back up whenever there's a 15 sec idle window, regardless of the minimum? Can I safely make that 86400 seconds too, or does it do something else entirely?

Many thanks in advance.

Very often, Firefox asks at startup: “Should I open Firefox every time I restart my computer?” I don’t need this function, how can I remove this request forever?

There are only two buttons: 1. Yes, open Firefox 2. Not now :(

The last update (which was VERY rocky... I had to reinstall and functionality has NOT been great since) eliminated the Bookmarks icon from the top ribbon. I've looked through settings, but find no way to restore it. Can it be restored? I now have to click the menu, Settings, and THEN Bookmarks.

I am trying to activate the new free VPN feature, however your steps are not matching what's on my screen.

The first step from your [Set up VPN] article says:

"Look for the VPN setup prompt in the top-right corner of your Firefox toolbar.

   Click Next to begin the setup process. "

Yet I am not receiving this prompt.

I have logged into my account, encountered issues with my authenticator app and back up keys not being saved, and so signed up with a new mozilla account using my secondary google email. (This account I am raising this ticket with now. My primary account/email is [edited email from public] @gmail.com).

Hoping you can clarify or give an easy route into activating this wonderful new service you've announced. Am I right in understanding that it is different (ie. built-in and free?) to your Paid Service ?

Hi! I love Firefox, but on updates when my account signs out. I also lose all my Firefox profiles. Even when I sign in again, and sync everything on my Firefox account, I lose my primary and secondary profiles. Whilst it restores my bookmarks and extensions on my account. I lose my bookmarks etc. on my secondary profile.

I'm using FF on both Windows 11 and android, but this problem only effects Windows 11.

Cheers :)

Hello. I'd wriitten a few days ago about being blocked from firemountaingems.com I got help from Issis B. and was able to browse the site by turning off the VPN temporarily. Today, I am again blocked even with the temporary turn off of the VPN.

Is there a way you can show me easily step by step, how to exclude certain sites from the VPN permanently.

Thank you in adavance.

When I open mail.yahoo.com, I keep getting: "Something went wrong,We could not sign you in. Try again from a different device." what should I do? any other browser works fine, just firefox is block, I might stop using it very soon.

When I logged in this morning my FireFox screen had changed. The window for searches had disappeared and the "pocket" selections were all about India and its events. None of the previous options were there. What happened and how do I get back to where things were?

Windows Defender is blocking Yandex.Ru, which is not even been tried to be access from. It showed in the Event Viewer that firefox.exe tried to reach Yandex.ru. Why is Firefox trying to reach there? There are no extensions apart from Firefox Multi-Account Containers installed.

Please advice.

I had a ton of saved tabs and groupings of tabs. I closed what I thought was my only open Firefox window then downloaded and installed the most recent Windows update. When I rebooted, I did not realize I had left a Firefox window open with a single tab. That Firefox became my default and I lost all the tabs I had. Is there any way to get those tabs back? The tabs I had yesterday, 1/22/2026 are the ones I need.

Hello, I'm using Firefox 147.0.4 on Windows 11. When I open the Adobe Firefly website and I try to upload a file to the Adobe server using drag and drop or by browsing the Windows file system, nothing happens ... There's no error message, but the file isn't uploaded. Of course, this site works perfectly with Opera or Edge... On the Adobe forums, many users have the same problem with Firefox, and Adobe's response is always the same: change browsers ! Thank you for keeping me informed about the resolution of this problem, as I don't want to change browsers ! My email address is [edited email from community support forum]

Have a great day, Sincerely,

Mr. Fernandez
