You say, "Some essential Mozilla services are excluded from VPN routing to ensure sign-in, VPN reconnection, and screens needed to sign in for public Wi-Fi work properly. All other browsing activity in Firefox remains protected when the VPN is on."

How then am I protected in any kind of secure way?

All it would take is the Mozilla services using my public IP to lose my browsing protection. How are those connections secured to protect my identity from being exposed once the VPN is enabled and even after the VPN is enabled?

If the public IP can be discovered at sign-in, re-connections, and public Wi-Fi connections before the VPN is enabled, then that same public IP can be traced through internal logs to uncover all the VPN activity done after sign-in, re-connections, and public Wi-Fi access. So, how exactly can I trust the VPN protects my activity at all?

I'm just curious how you setup any protection prior to the VPN being enabled? I'm a former IT Network Specialist I had my CISCO CCNA certificate (Worked in school districts who wouldn't pay for additional certificates so I did all the study work and practice testing up to the CCNP certification just could never afford to take any of the exams beyond the CCNA). So, when I see these additional things like your 50 GB of free browser VPN and read how it works I get curious about the actual protections being provided. Are the people more vulnerable than they may be led to believe?

Hi everyone,

I’ve been experiencing synchronization issues with Firefox lately.

Current situation: Tabs sync correctly between devices, but bookmarks and passwords no longer sync between my iPhone and my computer.

I’ve also considered an issue with profiles, I currently have three Firefox profiles:

• default-release (currently in use)
• default
• default-release-1

I also used Firefox Troubleshoot Mode (restart with add-ons disabled) to test the issue.

sync-log : The sync-logs show many success-sync entries and only a couple of error-syncs. There are no obvious connection issues (I’m using a shared connection in a rural area). However, bookmarks and passwords are still not syncing properly across devices.

Observed behavior: Sync is active and "functional" Only specific data types (bookmarks and passwords) are affected The issue persists even after signing out and back into Sync, and restarting Firefox on both devices

Checks already done: Sync is enabled for bookmarks and passwords Sync logs mostly show successful operations rather than errors

Hypothesis: A Firefox profile conflict

Question: How can I restore Sync properly without losing my bookmarks, passwords, or other data?

Thank you for your help.

I have split viewing pane, but the preview on the right has an overlap so I can't see / preview the email. I have tried all "layout" choices but still can't get that line to go away so I can view who it is from AND the message. I have tried everything I know but that line remains.

One of my local folders of email disappeared: it is no longer displayed under Local Folders. A few days ago while using my mouse to move a message into one of the local folders, something happened, a peculiar message briefly displayed. At the time I did <Ctrl>-Z to undo whatever happened, but I didn't see any changes. That must be when the folder disappeared, but I'm not sure.

My other folders are still in place. I can't find the missing folder inside any of the other folders (junk, deleted, archive, etc.). Yet when I search for email in one of the missing folders, the messages are found. When I go into Troubleshooting Information, there is no Profile Directory listed, and when I click on the Open Directory button, nothing happens. (I've gone through the process of transferring Thunderbird accounts to new computers in the past.) I'm using Pop!_OS 22.04 Linux and Thunderbird 140.10.0esr. I backup my laptop using Back In Time. Any idea how can I fix this?

As of recently, I have problems with Firefox that do not happen in other browsers. But Firefox is my favorite, and I'd like to have this solved so I can keep using it.

In Zendesk, there is an option "Print ticket" which should open Print dialog and we then can print whole email to PDF. This worked for years, but as of recently that dialog simply does not show. I tried change Firefox settings for printing, but problem remains. Attached is a screenshot how it looks in chrome, and how it used to work in firefox.

As from yesterday, April 17, Firefox will not load correctly https://m365.cloud.microsoft page. It loads, but no element reacts when clicked. I cleared cache, cookies, removed extensions, refreshed firefox, but to no avail.

Thanks for the help!

suddenly a month after going to windows 11 when i go to firefox home page and try to search for something it loads a clean page but never goes to the page after I have hit enter. Causes me to go back to search page and then hit magnify icon to get to page I am looking for. This causes an extra stroke and is causing me to think about a new home page rather than firefox. Any help would be appreicated.

With Mozilla Firefox for Linux Mint 150.0 after logging into Chase Bank , when trying to pay off my credit card, I get a message: "It looks like this part of our site is not working right now". However the site works perfectly with Chrome, thus the problem must be with Firefox. I have cleared the Chase cookies and still getting the same result.

the new "experimental" account center doesn't work (version 150.0) how can I go back to the precedent account creation tool ? the option "experimental account center" is NOT checked, but I still have only the new creation account form.

3 дня назад перестали приходить письма - вышла ошибка авторизации. Пароль точно верный (через браузер все работает) и работает Thunderbird на другом ПК. Снес мозиллу, касперского, пробую заново создать почту, не дает, смотрите скриншот 1. Потов выдает ошибку смотрите скриншот 2. Вообще не могу понять что не так! На другом ПК все работает. переносил профиль с другого ПК на свой все тоже самое - ошибка авторизации. Куки разрешены, в исключения gmail.com добавил в Thunderbird Куда копать, что искать?

can one link the Mozilla focus app with the other Mozilla Firefox app? I want my Mozilla logins, bookmarks, and account info to be also available in the Mozilla focus app
