after working in firefox for a while and using a number of windows and the I close firefox with multiple windows open in my session. if i open it again and keep doing this for a while and then have closed firefox, eventually I can no longer open a firefox window and get a message the I have too many windows opn and can't open more till i close the open windows. i hover over the firefox app and all the previously closed windows are stacked up. why didn;t they close when i exited my firefox sessions. why are they still there and clogging up the system?

I'm trying to use the built-in VPN for Firefox, but when I try to click the "Get started" button, nothing happens. Is the service simply not available for me yet? I live in the United States, for reference.

Hi. Since the last 2 updates, my Bell sympatico email through T-bird cannot SEND anymore emails (No errors are given but the email never comes through). I can receive emails without issue and when I use another tool (like Outlook or go directly through my browser, the sympatico emails come through) I attached the settings for the SMTP in a screenshot if that could help.

Any idea how to fix this?

Tx, Robert Z.

After completion of the last Firefox update (150.0) I am no longer able to search ANY items in ebay. I can load the ebay page but if I click on any specific items (to view or bid on) I get a blank screen with an error message... Service Unavailable - Zero size object The server is temporarily unable to service your request. Please try again later.

I have cleaned cookies and deleted history. I have shut off and restarted my PC. I have gone to my backup laptop and using Microsoft Edge, accessed every ebay page without any issues. I can only assume that this issue is with Mozilla Firefox.

I am running Thunderbird 140.9.1esr on openSUSE Tumbleweed.

For a long time now, Thunderbird often runs at high CPU (80-100% of one core), for several minutes at a time (5-10 minutes). This seems to happen many times every day, with no apparent cause from my end. (I just got back from Lunch, and the fan on my laptop was going crazy because of the high CPU.)

What can we do to identify and fix this issue?

When copying and pasting from one application to another, by using Ctrl + Shift + V to paste without format to Google Docs, I keep getting a "Paste" pop up that I've never gotten until now. It keeps getting in the way and I don't see a way to remove it.

It's making copying and pasting very difficult and is driving me up the wall.

Default homepage is yahoo. Since the update to version 149, if I do a search from yahoo, the new tab that opens with the search result is blank most of the time. I have to click reload for the search results to show up.

Is anybody else having that problem? Seems to be yahoo search specific but not 100% sure.

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.
