I was wondering if anyone knew why I am having this issue. On occasion when I walk away from my computer with Firefox running (usually 20-30 minutes) I come back to find the browser itself has closed, including Private/Incognito tabs. Everything else on my computer has continued to function as per normal, nor has the computer itself seem to have restarted itself. It is only Firefox that this is happening with.

I have bought a new pc with Windows 11 home pre-installed and set Mozilla Firefox latest version as default browser ...the issue i am having is placing add-on extension shortcut icons on toolbar. I installed Norton Safe Web and this installed ok and is listed in extension control panel and when i click puzzle icon Norton Safe Web is not shown under manage shortcuts nor can i see option to Pin to Toolbar. Have tried several attempts but still get nowhere.I uninstalled Mozilla Firefox...restarted pc ... did a fresh install of Mozilla Firefox without altering any settings..re-installed Norton Safe Web and still cannot see option to Pin to Toolbar.Clicking the gear icon does not help Have i missed a step somewhere ?

I have no usable Menu options at the top of the Thunderbird email screen. I hit a wrong key yesterday and things such as Write, Reply, Print, Send, Delete, Junk, etc. have disappeared. I read some possible things to help but I do not have III on the upper right of my screen and pressing Alt when opening Thunderbird also does not work. HELP!

TB 102.10.0, Outlook 2010: Imported mail message (local) folders: At least one folder is incorrectly indexed (dozens of similar messages are all indexed as same subject line and same time and date). How do I either re-index or re-import? (Incomplete check of folders show same number of messages in Outlook and TB in all I checked.)

Accounts are all IMAP, and of course online messages are okay.

When I click on theThunderbird icon to check my email, it says “Enter your password for ricc (the first part of my email) on imap shaw.ca” but don;t know what it is. I phoned my ISP, but they just said contact Thunderbird. So can you please help?

Similar to an earlier post (https://support.mozilla.org/en-US/questions/1398079), I have been using TB to connect to yahoo accounts without issue for years, but about a month ago one of two yahoo email accounts failed. Since one of the accounts still works without issue, not clear what's going on?

Ubuntu 22.04 Thunderbird 102.11.0 (64-bit)

I think perhaps it's the email account add / configuration step for several reasons. Let's call the account that works "A" and the not-working broken account "B". Early on, I deleted the "B" account and have since been trying to get this to work again. During the "add account" step, I've let TB configure automatically, which yields the same server info as "A", so I don't think that's an issue; The settings that show up when attempting to add "B" (same as "A") are in a screenshot. After you click "Done", there's a pop up to get Yahoo's password. I enter this, then click yes to the agreement, and *immediately* get the authentication error (another screenshot). The speed of this error is what has me suspicious. It made me think some local files somehow have incorrect info. I tried clearing history ("everything") and restarting, but same story.

Unfortunately, the earlier question doesn't have an answer. Any more clues about this?

Thanks in advance

Since a few versions ago, I am unable to scroll Firefox Suggest list when typing in address bar.

I heavily rely on history in my browsing. A few versions ago I was able to start typing in the address bar, which triggered 2 lists: (1) list of search engine suggestions and (2) a list named Firefox Suggest that was scrollable and included my bookmarks and history entries containing the typed text.

Currently, the Firefox Suggest list is only 2 rows long and is not scrollable; attempting to scroll closes the entire search window.

Is it possible to fix this? I tried to reinstall Firefox on my iPhone, with didn't help.

TBird v102.12.0, 32bit, WIn7Ent.

Just started this morning, I'm getting the following error on one POP3 account:

The stat command did not succeed error getting message number and sizes mail server outlook.office.365.com responded server unavailable 21

This is happening only in TBird--I can get that account's email via my iPhone's built in email app--and it is happening on multiple PCs that are similarly configured.

I have multiple accounts set up on office365 (via GoDaddy). Others are working fine with the same settings.

What I have done so far, with no joy:

I have successfully logged into Office365 directly

I have regressed to an earlier version of TBird.

I have deleted and recreated the problem account (which required resetting the password). The deletion/recreation succeeded, but email will still not download for that account.

I prefer not to use IMAP.

When I enter either of these internal addresses, it fails:

http://dfa shows: Hmm. We’re having trouble finding that site. We can’t connect to the server at dfa.

http://rpi-m92a-ad82:3003/ Hmm. We’re having trouble finding that site. We can’t connect to the server at rpi-m92a-ad82.

Both issues are similar, but neither work as expected.

dfa is an alias for a longer name such as dfa.int.example.com. The local DNS (/etc/resolv.conf) will reply with the correct IP if asked for "dfa" but not "dfa." due to the dot forcing the Fully Qualified Domain Name to be "dfa." only. We wish to opt to leave off the rest of the url.

For the raspberry pi, it is a mDNS. So doing "rpi-m92a-ad82.local" works. But this used to work long ago, and ended 10 or 20 updates ago as best as I can remember.

How can I convince Firefox to query DNS, then query mDNS, and if both fail perform a search?

Thunderbird downloaded it's newest version into my computer & all emails from 2003 up to yesterday are gone. Hopefully they exist somewhere & would like to retrieve them.

I’m trying to transfer my iPhone Firefox tabs (All 100+ of them) to my Mac laptop Firefox. I have already signed in before and I would really like some other way to transfer tabs than to tediously click every tab from the Firefox account drop down menu. The Firefox help page for setting up sync don’t help since I still need to click every one of those tabs from the drop down menu. If there is something I’m missing about the process can someone please explain it to me, and it would be greatly appreciated if someone to help me find a way to transfer my tabs all at once.

Please help. My seamless syncing is not seamless. Laptop has win11, version 114, all the necessary options, but my phone has no in-browser scan accessed through the missing 'sync and save data' option. I remain a loyal (2004) user. Thank you

I have a BT Business email account, btconnect.com which today stopped working. I contacted BT who said that Microsoft no longer support Pop email and the only way is to access via Outlook365 and I can no longer use a 3rd party mail client. I managed to set up a gmail account in Thunderbird and forwarded my BT email to that account, however every few seconds I get a warning to say bt password is incorrect so I deleted the bt account from Thunderbird, Along with all my important emails and folders. How can I recover these ? I have found Files & Folders in Profiles, but how do I get these back into Thunderbird ?
