Since a couple of days, the sidebar on the left disappears when restarting the browser. I am using 138.0.1. Everytime I have to go to settings to make it appear. Can you help on this bug?

Been using Firefox for many years. Configured the Firefox Browser to automatically open the Sidebar Bookmarks every time I open Firefox browser. About a week ago that configuration stopped working and I can not re-set it to automatically open the Sidebar Bookmarks when I open the Mozilla browser. When I search online I see I am not the only user of Firefox who has developed this same problem. I suspect it occurred when Firefox updated their browser. Would appreciate getting that feature restored as it is annoying to have to open the Sidebar Bookmarks every time I open and use Firefox browser. No, I am not going to leave it open when I stop using my computer to solve the problem. I close all my apps and shut my computer down after using it. If this cannot be fixed my only alternative is to stop using Firefox and find a new browser.

If I am doing something wrong please advise!

I've followed Thunderbird setup according to "Automatic Conversion of Google mail accounts to OAuth 2.0 Authentication" (https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20) The failure is described in my initial post below:

Mozilla Support - Signin, and use of Thunderbird https://support.mozilla.org/en-US/questions/1484529#answer-1729438

LarryGad post (Reply to Ashley LambertonQuestion owner): I get the same screenshot Ashley posted above. But...clicking Allow doesn't download my Gmail messages. And clicking the link, Account Permissions, just produces a blank window. An idiosyncrasy is I'm the domain administrator for a "Free Legacy Edition of G Suite for personal use".

This paragraph may not be relevant to the above issue. I did stumble across the Account settings link (https://myaccount.google.com/general-light?pli=1) which contains the line: 'Connected accounts View and manage your accounts from other services' Clicking the 'View ...' link goes to https://profiles.google.com/connectedaccounts and displays the message: "404. That’s an error. The requested URL was not found on this server. That’s all we know." Highlighting the 'View ...' link shows https://profiles.google.com/connectedaccounts?authuser=0

Thanks in advance.

Hello. I just bought a new Samsung Galaxy s24 Android phone and Smart Switch was used to transfer the data from the old Samsung phone to the new phone. The problem is that my Firefox passwords and bookmarks are missing on my new phone. However, they still exist on the old Android phone. How do I get them over to the new phone? Firefox was last updated on 4/21/25. I have a .csv file on the new phone that came from a different password manager on my desktop if that helps. Thank you so much for your help.

I have followed the instruction https://support.mozilla.org/de/kb/Benutzerprofile-Thunderbird#w_ein-profil-sichern to shift my profile from one harddrive to an other on my PC

The original profile is still on the old location %APPDATA%/Thunderbird I have updatet profiles.ini pointing to the new location At first glance it seemed to work Thunderbird was starting and when I cloesd it the date of files in the new location changed. But when I renamed the old profile in the old location Thunderbird does not start correctly and I only get

   <menuitem id="folderPaneContext-getMessages"
</pre>
^
If I rename the old profiles again to the original names, it starts without any issues

Tools>options>privacy & security>Passwords. Click 'show passwords' brings up the saved passwords in a separate box. Need ability to resize the box (and colums within the box). The columns are too small to see the entire contents of a column. Using TB 138.0

Matt replied to my question last night (thanks Matt), but when I went into my account to respond I couldn't find my original question thread to answer him. Maybe it is the time difference? (I'm in Australia)

My original question was:

I can read my emails but I can't delete or action my emails. They're just piling up in the inbox. Sometimes, I can delete just one and then, it stops deleting. Sometimes the New Message icon is brown and sometimes green. I have no idea why it changes colours.

I've been using Thunderbird for over 10 years and it's been great with no problems.

I'm a bit of a luddite and I'm finding the new changes are doing my head in. It doesn't work for me now.

I give a monthly donation to Thunderbird to support the work being done, but if I can't use my emails, I'll need to change from Mozilla to another email system.

I'd appreciate help, and, also appreciate some advice about how I find a response that is sent to me when I go back to Support to answer it. Thanks.
