Does Firefox VPN not work with DNS over HTTPS set to Max Protection, and when using a custom provider?

With the VPN on and DNS over HTTPS set to Max Protection set to custom provider, no pages will load and I get an error screen/can't connect to proxy screen.

I was using Firerox Beta on Android and yesterday or for the last couple days my Firerox account would keep getting logged out as in I'd have to sign in again and again to sync or send tabs to other devices. (It would repeatedly say sign in again to sync even after I sign in repeatedly).

I uninstalled Firefox Beta and installed Firefox stable on Android. No such issue so far.

Can`t install on my account therese.drioscoll12@hotmail.com I just create yesterday. I can read outlook program. There is something wrong I don`t know what top do. Therese Driscoll# * Numbered list item

My old provider has stopped supporting my old email address and I have changed to a gmail address. How do I remove the IMAP and smtp settings etc for my old email address? Also remove all trace of that unwanted old address please?

I found some information about deleting closed tabs from Firefox.

Please allow users to select a date or date range instead of a maximum number of tabs and windows. Computers often restart, for instance when installing updates, and some sessions will include more tabs than others.

Thanks in advance!

I can not seem to find the button to open a saved, closed tab group. I have googled, and there seems to be a lot of people with the same issue. However, None of the information given under those forums provides me with a clear, easy solution. Please help.

Malwarebytes is picking up and blocking an outbound connection request from Firefox - www.highperformance.com. Anyone else experiencing this?

I really can't add to my Summary other than it's a fairly recent issue, started in May 2026, possible April. About.config is set to False. I hope some has a solution - it happens when I'm dealing with live incidents.

I've been a loyal Firefox user since version 2.0. but to this day you guys have not made it easier for users to restore Firefox profiles. We in 2026 should be able to do the following directly from the user interface of Firefox. honestly its really taken me a long time to voice this opinion but it makes the app a tad less user friendly. i mean its easier to import from another browser but you have to pull out and search all sorts of folders to import from an old Firefox installation or a windows refresh (windows.old). Please, please implement this ASAP. we users have waited too long.

1. display a list of profiles (even from windows.old after a windows refresh) 2. automatically import that information 3. append existing bookmarks from the bookmarks backup if i choose to. 4. be able to browse the bookmarks and show the most recently used ones 5. be able to even reinstall the existing plugins (this one is minor)

the image attached is exactly showing what happens after a windows refresh. this feature is also great for administrators.

I've been using Thunderbird for years but suddenly as of yesterday it's stopped receiving messages. First it told me my password was incorrect. Ever since then when I try to click "Get Messages," it simply has no response at all. Nothing happens. I went into my Thunderbird password settings, and upon seeing that the incoming-message password had for some reason reverted to an old, obsolete password, I corrected it and saved the correct one. I've checked several times and the passwords are correctly saved now. But this did not fix the problem. When I click "Get Messages," nothing happens. My Thunderbird is connected to my Earthlink account, which is working fine. When I go into Earthlink, I am able to send and receive messages as normal. So the problem is not with Earthlink but with Thunderbird.

Hi all,

I've been using Thunderbird for eons but yesterday morning it started freezing up constantly.

It freezes up ("Thunderbird is not responding") every time new emails are received or any time I take any action while the Inbox folder is open. So, if I delete an email it freezes for a few minutes. If I do anything pretty much, it freezes up for a few minutes. Then it comes back and I can do another action, and it freezes again. This only seems to be happening when I have the Inbox open - if I go to other folders it seems to function normally.

Things I've tried without success: - Troubleshooting mode - Adding exceptions for my profile folders to Windows Defender - Compressing Inbox (and Trash and Junk) - Repairing the Inbox index

This doesn't appear to be a memory issue - right now, memory use for my entire system seems to be hovering at just over 50%. But Thunderbird is still freezing.

My Inbox folder is very large, but it's never been an issue before and nothing significant was added yesterday when it started failing.

Any suggestions appreciated!

Thanks

I'm using Thunderbird 151.0.1. After 151.0.0 was installed, the ability to press "/" ("slash") to search while viewing a message was broken. The slash is ignored, and following keystrokes are then acted upon.

If a search is initiated by pressing Ctrl+F, subsequent searches can be started with a slash. It's only when the first search is done that the slash is ignored.

I've been using Thunderbird since the beginning, so starting a search with a slash is in my muscle memory. As a result, I've inadvertently marked or archived or starred messages, navigated to the next thread or next unread message, etc.

Looking at the release notes, I see that a search function was fixed in 151.0.0. I wonder if this is related to that fix?

In any event, can "press slash to start a search in the message window" be restored? ...thanks!

Yesterday I had to change my Spectrum email - I have an old road runner email address and swapped over to spectrum.net server from the old server. In this process I had to update my password to access the server.

When I updated per the instructions from Spectrum I was able to do a normal download into my Thunderbird inbox. This triggered me having to input the new password. I did check the box to update the password and save it. After the one time download I cannot get Thunderbird to download emails. I can send emails with no problems but cannot download. No way can I get a download - it does not on initialization, at the set time nor with the manual request.

Spectrum is no help - their web mail works and it's my problem. I realize this is an old system, legacy and all that - anybody got a magic fix?

Any idea on how I messed this up?

Thanks.
