In other browsers (Brave, for example, and Chrome) I can open a drop down menu, and while holding Ctrl choose multiple sites to view. In Firefox, if I drop the menu and choose one site, the menu disappears before I can choose others, even if I hold the Ctrl key. I have to reopen the menu for every site I want from that menu. Is there a way to make FF act like other browsers in this respect?

Why are specific relay emails being sent to spam despite having a filter, and only being removed when the filter is run manualy?

I'm running the current 157.0.1 release on Windows 11, and specifically am having my emails from the AP be sent to spam even though I have a specific filter set to tag them. I feel as if the filter itself is set up properly because when I manually run it the messages will be moved from the spam folder to the inbox and tagged accordingly.

The one thing sticking out to me is these emails are being forwarded through my relay account. I've tried changing the filter to work based on the relay address, but again it only works when I manually run it. I've also tried setting the filter to run both before "and" after spam classification, but neither option works. Ideally the filter would work without me having to go to my spam and run it, and even then I'm wondering why the spam filter hasn't learned by now that those email belong in my inbox.

I'd appreciate any help or solutions; I'm not an email power user or networking wiz though so please try to keep it as dumbed down for me as possible!

Desktop version update to 157.0.1 acted like a fresh install. Prompted me to import from previous browser. Firefox was my previous browser. I have my bookmarks backed up, but lost all my tab groups, which is a huge problem to try and recreate. Lost downloaded themes. Lost downloaded extensions. Why did this happen? I can't imagine it was by design.

As for my future use of Firefox and involvement with Mozilla I am very seriously considering NO further use of both and your claims are starting to become lies you are permitting tracking in my view of this behavior Community Members should not be dealing with these concerns GET OFF your lazy back side Mozilla

I'm getting a popup error message saying "Unable to write the email to the mailbox" on one of my gmail accounts. This has happened a few times before and I'm not sure how I managed to get it working again those times, seems hit-or-miss. I've compacted and run a repair on the inbox folder several times as suggested by others. I've updated and restarted Thunderbird and even updated windows and restarted more than once.

I recently updated my Firefox to v158 from v156, and now the text colors of some of the UI elements on a new tab (e.g. Firefox wordmark, web shortcuts, Recent Activity header) which were previously white, have been changed to black (or a color close to black).

I use a custom wallpaper for new tabs, which didn't alter these particular colors on v156. Switching the background in the Customize menu shows the white text on some of the default wallpapers and the dark text on others. I have attached example screenshots to show how these elements looked before and after the update. I used the Developer Tools console to do this.

I assume this has to do with the "modernized" Nova UI redesign (which I have disabled) Mozilla is now forcing on its userbase instead of making it optional. Reverting these properties via the Developer Tools console does not make them permanent. I would rather not have to change my current wallpaper if I can help it.

Is there any other way I can make the text white again without changing the background or downgrading? Or if I can make them permanent with the console?

Using Thunderbird 115.18.0esr Supernova 64-bit on Mac laptop OS 10.13.6. Worked fine for years, with ongoing Thunderbird updates, even though Mac OS is 32-bit. Suddenly, after 10/6/26 can't retrieve emails although I can see them on the ATT Yahoo server website. Can still send emails with Thunderbird. Inbound server settings are: POP server inbound.att.net, Port 995, SSL/TLS, Normal Password (I long ago created a Secure Mail Key, and even tried creating a new one). But inbound server name doesn't show in Saved Passwords (only outbound server with Secure Mail Key as password)? I have tried everything suggested, repaired my inbox folder, updated Thunderbird files, etc. in Profile as recommended. But still no prompt for password when attempting to get messages. Just shows "Done" at bottom left with no new messages received. But new messages are seen on server website. So it appears that Thunderbird isn't able to connect to the ATT Yahoo server to get emails. Why? And what else can I do? I love Thunderbird and want to continue using it.

Can’t copy and paste Firefox folders to another location.

The problem: You’re the administrator of your Windows 11 computer, but you can’t copy, rename, or change your browser’s data folders (Firefox, Brave, Chrome, Edge). Windows says “You require permission from [your own name]” or “Access denied.” Closing the browser doesn’t help, and the usual fixes for permission problems don’t work either.

The cause (in my case): It wasn’t Windows. My ESET antivirus (ESET Smart Security Premium) has a setting called “Enhanced data protection.” It’s meant to stop password-stealing programs from reading your browser’s data, but it also blocks you from copying or renaming those folders. Starting your computer in Safe Mode may also let you get around the block, since antivirus programs don’t fully load there.

The fix (ESET): 1. Open ESET and click “Setup” on the left. 2. Click “Advanced setup” at the bottom right. 3. On the left, click “Protections”, then “Browser protection”. 4. Find “Safe Banking & Browsing”, then the section called “Secured browser”. 5. Turn off “Enhanced data protection” and click OK. 6. Try copying or renaming your folder again. It worked for me right away. Afterward, turn the setting back on to stay protected. If you’d rather leave it on, ESET has a “Browser protection allowlist” where you can add programs you trust.

Using a different antivirus? Look in its settings for something about browser protection, banking protection, or protecting browser data. A similar feature may be doing the same thing, though I only confirmed this with ESET. Technical note for those who want it: I confirmed ESET was active by running “fltmc” in an elevated Command Prompt, which listed ESET’s file protection driver (“eamonm”). Another user on Microsoft’s support forum found the same cause with a Chrome profile.
