Hi

When Thunderbird is started maximized it overlap taskbar if is set to hide and taskbar won't show until Thunderbird is minimized and maximized. Another way is to press the Win key two times. Then the hided taskbar can be shown/use. The same thing happens to Firefox. Only when is first started. Then if Firefox is minimized and maximized, press Win key two times, press F11 two times then the hided taskbar show/hide normal.

It is a setting that can be changed to start Thunderbird and Firefox in full screen and do not overlap hided taskbar?

Firefox will only start if I sign in as an administrator. It doesn't connect to the internet, and I can't get to the help screen. I did a refresh but that hasn't help. If I uninstall and then reinstall a new copy correct the problem? How do I save and reinstall my bookmarks and settings? I love Firefox and prefer it over other browsers. But I need to fix it and any help you provide will be very much appreciated. Thank you!

with this new version i lost everything i need to get back to an older version and get all my extentions my bookmarks back all my s desktop items that i had linked to firefox are gone i can no longer get face book or anything back to firefox book marks every thing i had with firefox

FF is offering up possible login names for a particular site I have used previously even though I have removed all related browsing history, form data, and cookies (and cleared the cache). What am I missing? Is it using stored history for unrelated sites to guess at a user name, or is there some other hidden history I need to clear?

In all webpages, including Firefox settings pages, text appears like poorly chosen Cleartype settings. This does NOT apply to the menu and Address bars, nor the drop down options in "Which topic best describes your question?" that appears when asking a question here. Troubleshooting mode does NOT solve this, however switching profiles DOES, so I imagine there is a setting responsible for this however I've reset all font-related settings I could find. I've attached a screenshot of the result on this page. Choosing alternative fonts does NOT solve this.

Sometimes when I click on a stored bookmark all I get is a white page and no info.? when this happens I right click on the firefox icon in the taskbar and go to a new private window and after that I can get to the bookmarked site. wondering why this happens at times. I am using windows 10 for now but am planning to build another computer with windows 11 in the future.

I've tried setting up Thunderbird archiving according to the documentation to save archived messages locally, and in the same hierarchy they had when I archived them. That is, if I have:

INBOX

   Box1
   Box2

... etc. then archiving would create a parallel structure in Local Folders

However, this isn't working.

I select "Keep message archives in Other (Archives on Local Folders).

For "Archive Options" I select "A single folder", "Keep existing folder structure of archived messages" and "Recreate inbox folder".

However, when I archive something, Thunderbird just creates a folder "2026" (this year) and puts the message in there.

Why are my settings NOT working?

I like to default to having threading on. It used to be that when I opened my Inbox, every email thread was closed/collapsed. Now they're open (started somewhat recently).

I can get numerous separate emails where each one can generate lots of responses, meaning they threads get long, sometimes within a few minutes or hours. Having them closed by default (rather than open or unthreaded) makes it to see each individual email chain and other interspersed single emails.

I tried google searching; also tried threaded and grouped by sort (with the default sort set to thread), and it doesn't seem to help. Any help would be appreciated!

My shortcuts keep disappearing from my home page when I turn my computer on. Sometimes it's fine, sometimes I have to spend a long time trying to find them. Sometimes I just have to restart Firefox. Sometimes I have to go into settings. Sometimes I can't work it out.

Has been happening for the past month or so.

Dear Mozilla, I have enjoyed Firefox and I always appreciated the vast headline stories recommended in the past. Recently, there seems to be a change where every recommended article requires a paid subscription, i.e. Slate Plus, I already pay WAPO, NYT, WSJ, San Diego Union Tribune, Arizona Republic that i cannot afford to pay each and every website. I would be very happy if you could tell me where in my settings i can set it to show only free articles or perhaps my screen could show a little green dollar sign saying if article was behind a paywall. thank you for your time in reading and assistance.

Not sure if "browse" is the correct topic but here we go:

After a random crash (I don't remember the details, been a while) I've "refreshed" Firefox. Following that I started to have some problems with Google Meet. Haven't had any for years and suddenly when i open Google Meet (working from home and using Google Meet as an online meeting platform daily), everything becomes unresponsive. I can't change tab, cannot close Firefox from the close button, nothing. I open the Windows Task Manager and End Task manually to close the window so I can restart the browser. After restarting Firefox and launch Google Meet, it doesn't crash.

The other problem is when I try to watch something on Netflix, I hear the sound, see the subtitles but the video content is not present. It's just black screen with UI on it. Yes, I checked the DRM setting and no, other streaming services that I use don't have this problem. I can bypass this by launching Firefox in troubleshoot mode but I want to use my extensions. I even tried to enable them one-by-one to see if anyone causing problems but even when I disable all of my extensions like in the troubleshoot mode I'm still having the same problem.

I tried several solutions that I found on reddit etc. but nothing worked so far. I also re-installed Firefox and nothing changed.

Please help me before I lose my mind (:

Since the 26th of Feb. my thunderbird stopped downloading emails from any of my GMail accounts. I've accessed the email and i have a bunch of new emails there but for some reason they are not transferred to thunderbird anymore. I'm think i've installed a new thunderbird version around that time but im not really sure if that was the cause.

Also, no error message appears. it just says no new emails.

Already cleared the login details and logged again, still same issue. I'm using pop connection.

When I'm on my phone and signed into my Firefox I want to be able to send tabs to my desktop. I'll click the three dots on my Samsung 20fe, click share, and click send to device. My p.c. is listed and when i click on it, a box pop's up and says "tab sent. I don't know where it's going, but it's not making it to my desk top. I've tried logging out and logging back in. on both devises

today, when I clicked on the Thunderbird icon (on my desktop PC), instead of my usual window popping up, an odd looking window came up instead that asked to sign into my account using my username, email address or mobile number. But when I tried (several times), none of them were recognised and now I can't access any of my emails because now when I try I get a message that says "Edge: Too many requests" ... this is followed by a pop-up window (bottom right), that says, "Authentication Failure while connecting to server imap.aol.com. This in turn is followed by another Crash Report window (attached screenshot).

I tried uninstalling Thunderbird, deleting cookies, etc, then reinstalling ... but no change.

Hi Everyone,

I’m Harmandeep Singh Kandhari from India, A Health and Wellness Motivator and Now, Recently, my Mozilla Firefox browser has started using much more memory than usual, and multiple tabs cause noticeable slowdowns. I haven’t installed many new extensions. What steps can I take to identify the cause and optimize Firefox performance without resetting my entire browser profile? 🦊💻

Thanks, Harmandeep Singh Kandhari

Hi all — I’m running into a persistent threading issue in Thunderbird (v.148) vthat survives profile rebuilds and affects only specific conversations.

Symptoms Some threads show the expand/collapse carrot normally.

Other threads (same accounts, same folders, same time period) do not show the carrot.

The pattern is consistent: the same conversations fail before and after a full profile rebuild.

Both Inbox and Sent show a mix of threaded and unthreaded conversations.

No global setting seems to be wrong, because most threads work correctly.

What I’ve already checked mail.strict_threading = false

mail.thread_without_re = true

View → Sort By → Threaded

View → Threads → All

Folder Repair on Inbox and Sent

Full profile rebuild

Re‑added all accounts

Rebuilt .msf files

Verified that threading works across folders (Inbox ↔ Sent)

Verified that threading works across accounts

Verified that threading works for most conversations

Header checks For the conversations that do thread, headers look normal.

For the conversations that don’t thread, the headers also appear normal:

Message-ID: present

In-Reply-To: present

References: present

No obvious corruption, malformed IDs, or missing brackets.

What I’m trying to understand Why would Thunderbird:

Successfully thread most conversations

Fail to thread specific conversations

Preserve the same failures before and after a rebuild

Show carrots in Inbox but not in Sent for the same conversation

Show no global misconfiguration

Is there a known edge case where Thunderbird rejects a thread even when the headers appear correct?

Are there hidden rules about ambiguous References: chains, multi‑server storage, or cross‑account BCC workflows that could cause this?

Any insight into how Thunderbird decides not to show a carrot would be appreciated.

Thanks in advance.
