Concurrent with the most recent automatic windows update (may or may not be the problem), Firefox with duck-duck-go will not go to almost any site. All I get is a spinning icon or a blank page, not even any error messages. This was even true trying to go to this page until I restarted in trouble shooting mode. Until I can get Firefox working again I have been using Chrome with duck-duck-go. Note any search, i.e. 'hotels in Italy' or even 'MSN' do the same: spinning icon or blank page!! Any help would be appreciated. Also I noticed that my bookmarks were missing and there was no bookmarks drop-down on my tools line. I have run malware bytes and it showed clean, same with CCleaner. I have re-installed Firefox; no difference. Please help. and also, any way to find and replace my extensive bookmarks list? I have reduced my privacy to near zero and turned off firewalls and all limits I could find while testing for that. That did not change anything.

Could someone please help me with this.

Greetings everyone,

I've had this problem for a while and I don't know what to do.

I had a problem where Firefox kept crashing before it had finished loading up all of my former tabs and windows and so I was given the option of opening Firefox in "Safe mode" which I did, but now Firefox only starts in "Safe mode"...

I'm running the most up to date version of Firefox.

Thank you for any help!

I am struggling with Gmail and Yahoo mail account in TB these few days. I hit almost the same errors from both. I generated app password for Yahoo mail, and put it in when setting up new account. For connection security: SSL/TLS For authentication method: tried with Normal password, Encrypted password, and OAuth2 However, I am seeing the expected authentication window pop up when trying the OAuth2. For all three authentication method: errors are always the same --- unable to connect to your IMAP server. I've followed another instruction to change maximum number of server connections to cache into 1 or 10. Error messages were the same imap one. So, what should I do/try for next?

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.

Elsewhere, where my desk top has always been recognized, I'm now forced to log in each time...and I receive an email that a new device has just logged into my account. All of this suspiciously coincides with a recent browser update. On my bank feedback it's showing as Firefox "125"...when all previous logins were recorded as Firefox "124". Help!

I'm using the OneTab add-on, Enabled. The icon no longer shows on the Toolbar, though it is on the Menu bar next to Firefox View.

I ran Remove and then Added it again, hoping the Toolbar Icon would reappear = no go, And I lost all URLs already saved, stupid me. To be clear, clicking the Icon on the Toolbar saves all open tabs.

Is there a fix via Preferences? Thanks. gw

Yesterday, whenever I tried to open Thunderbird I got a This app will not open on your PC Windows error, and Word and Excel would not work. Apparently I had some Windows 10 problems which I was able to repair with Windows Resource Protection. Thunderbird now runs, but all 2000 of my Inbox messages do not appear. If I open my Mail folder in my Profile, I see the four folders inbound.att.net, inbound.att-1.net, inbound.att-2.net, and inbound.att-3.net The size of each of these inbound Mail folders is 5MB, 9.8GB, 38MB and 20MB. So, all of the missing Inbox emails are in the inbound.att-1.net folder but they don't show up. I tried deleting the .msf file. That didn't help.

Does anyone have any suggestions?

I have had a few emails that did not show up in the inbox listing, so the message count at the top indicated more messages than were listed. Doing a search showed them, and by moving them from the search results to another folder, and then re-searching and moving them back, caused most of them to appear. But not all - I still have a message count of 20, but only 19 listed, see photo 1. Photo 2 shows the hidden email (from Barry Chandler). So the email is there, it's just not visible!

Hi,

About a month ago I accidentally activated the "Delete all but the most recent 2000 messages" option for one of my mail account in Thunderbird (15.10.1 (64-bit) on a MacBook Air). Luckily our local support were able to restore the affected folders. BUT - every time I opened the restored folders in Thunderbird, all the restored messages would disappear again. Correspondingly, the support team can see at this time large numbers of messages being deleted.

I've tried to delete the affected mail account from Thunderbird - didn't help. I've hidden my profile and started Thunderbird from scratch, set up the mail account again (so there should have been no leftover information from any previous instance of the account) - didn't help. I can see that whenever I open a folder for the first time, Thunderbird says "Compacting" - this is even though I have "Always ask before compacting" set. Even after I turn off automatic compacting for space saving >20MB, Thunderbird still compacts when it first sees a folder.

I have verified this behaviour by connecting to the same mail server using alpine - I see messages flagged for deletion in the restored folder; as soon as Thunderbird touches the folder, they disappear (even though no compacting should be happening and I should be prompted before it does, see above). Conversely, if I remove the "to delete" mark from the messages using alpine and then open a folder in Thunderbird, the messages are visible there.

From my understanding of what Thunderbird should be doing when compacting (or rather when not compacting), I would say the behaviours I've seen are rather significant bugs. But if I've misunderstood and there is some other way to stop Thunderbird from purging messages marked for deletion, I would be grateful for any advice.

Many thanks in advance for your help.

Hi

Got an earlier version of Thunderbird at home (and sorted fine) but I'm trying to sort the view for folders and sub-folders to be all the same on my work PC i.e Sort By: Date, descending & unthreaded.

Apart from going through every folder/sub-folder, is there a quick way to set this in version 115.10.1 ?

Looked at online help/videos but they refer to older versions.
