I have used firefox for years as my browser with my home page set to google. I have always had a bookmarks toolbar but never a bookmarks side bar and do not want one. The other day a bookmarks side bar suddenly appeared. I have moved it from left side to right side and can delete it temporarily by using CTRL +B, but can't find a way to permanently remove it, i.e. make the default setting so that the side bar doesn't appear. can you help?

Sync just does NOT work. I installed FF on my Mac brand new and fresh... brand new machine. Signed into Sync. NOTHING. After 6-7 HOURS... nothing. It just gets NOTHING AT ALL from my Windows Desktop.

I've signed out of ALL Firefox/Mozilla sync sessions... signed in clean- all browsers are up to date. And the about:sync-log page shows a LONG streak of errors... NON STOP ERRORS.

Why?! Why can't we just sync extensions to install and bookmarks across machines? How is this that hard for Mozilla?!

Day after day and attempt after attempt of failures for a basic function of the browser.

Here is the text of the latest log and showing constant connection errors- mind you NOTHING is breaking on my internet as I'm often streaming things and watching stuff while surfing, or others in the house are. Our connection, and Firefox getting online, are all working fine. I am at a loss. I don't understand how this is so terribly broken out of the box that you can't just sign in and let it talk to their servers. I know Google has billions behind Chrome, but this shouldn't be so 1990's bad by comparison to Chrome sync.

ATT made me change my email password which restored my access to email on yahoo. Thunderbird isn't accepting the new password. (It did open to show my emails going back to 4/17/2023 after I entered the new password.) I get a message that log in to server failed. Then a window opens to enter new password. Already entered the new (correct) password that works on yahoo. How do I get Thunderbird to work again?

I'm having trouble using my bank's website. Sometimes I can't log on (error messages) or I can log on and can't use certain features. The bank is Regions. The site works with other browsers. Is there some setting on the latest Firefox that needs to be adjusted? The articles I've read don't help. Thanks.

Sadly I had to thoroughly uninstall Thunderbird, reinstall and create new mailboxes due to some strange reason. In the past, the inbox would show the email list and, if clicked, a message would show up below a separator line. Now only the list shows up and I have to double click to read it which opens a new window. What a pain!

And yes, I know I can view the message page using F8 but it is on the right side and shorten the other windows.

Is there a way to go back to the view option I had in previously?

I just lost several hundred tabs on Firefox mobile right after it updated itself. The most recent tabs show only ten of those tabs, which were all opened and closed today and aren't part of what I need to restore.

How do I get my tabs back? I've seen no 'restore previous session' option. My laptop only shows the few I have open now. What do I do to restore them?

When I delete a message, I would like to stop TB from automatically opening the next (or previous) email.

I have seen this question asked several times over the years but none of the suggested ways (mostly add-ons) work anymore. One add-on was called Mail Tweak and another was called Deselect On Delete but neither is currently available.

Is there a way to do this today?

Hi, After using Thunderbird for years without problems, I ran into a serious one now (since a few days). When starting Thunderbird it comes up with three almost empty windows, one over the other. No data is filled in and when clicking on the window it says in the upper left corner: Starting page - Modzilla Thunderbird (no response) / (actually in German) Startseite - Modzilla Thunderbird (Keine Rückmeldung). The small login popup is also seen in the window but doesn't accept any typing and shows also 'Keine Rückmeldung / no response'. I can only stop the process on Windows level. I would be very grateful if you could help me with this issue. I cannot get to my emails anymore. Many thanks Holger

Hello, since upgrading to 115 Thunderbird has disabled all add-ons, and does not have an option to reenable them. This was done to several extensions which are not marked as incompatible including "NestedQuote Remover" and "Unmangle Outlook Safelinks". Removing and uninstalling them solves nothing. Indeed, the button to install from the market does not work. I had to save to and then install from a local file to test this.

I am not in trouble-shooting mode, but I have found that "Load Temporary Add-on" in debugging works for the current session.

(I tried searching Google and this forum to no avail.... only turning up irrelevant thread about older versions, Firefox etc.)

Using Thunderbird on Linux I cannot delete any local folders, when I try to delete them I get more copies of the folders on reopening Thunderbird, after the system says it is "not responding" and I close it down. I have tried several times and now have multiple copies of the local folders I've tried to delete.

Hi!

I'm trying to determine if I'm having a Firefox issue or not. I've been using Firefox for many years and frequently use private windows.

I've got a new laptop with Windows 11 and have been noticing that my private windows are sometimes closing unexpectedly. After which, I can't get my tabs back. This has only happened with private windows, and not regular windows.

Is this an issue that's being reported in the community? Thanks.

I post or write something on my homepage. I then want to share my post to groups I belong to. I hit the share button and get this new and poorly designed response to share. I go to the 'group' share icon. It then lists the groups I'm a member of. So far so good. I then click on one of my groups that I want to share the post with. I get a response, like previously before this new change, allowing to write something to the group along with the post/image I want to share. But there is no 'share' button that allows me to share the post. When this hideous new change came into effect there was a sliver of blue at the bottom, obviously from the share button, and clicking on this allowed me to share my post. Unfortunately, the next day when I attempted to share my post, the blue sliver disappeared and there was no way I could share it to a group. For some reason I cannot take a screenshot of what I'm writing about. Your thoughts?

When I would mouse-over a thumbnail on the Youtube home page I use to get a video preview with sound and text controls displayed. Video preview and controls are now missing on homepage thumbnails. Is there a way to get preview and controls back ?

I cleared the cache and cookies...no effect. Problem does not exist with Edge browser.

Using Windows 10 / Firefox browser 125.0.3 (64-bit)

After accidentally cutting power to my pc, Firefox has been crashing upon start. I've tried using Troubleshoot Mode, refreshing, reinstalling, and even manually deleting all my user data, but nothing has worked. These crashes do not appear in the crash logs, and happen instantly upon opening the program.

Oddly enough, using task manager to restart Windows Explorer stops the crashing, at least for thirty or so seconds (this is how I was able to try Troubleshoot Mode, as well as accessing logs). I have no idea why this is, nor if it's useful information.

I want to keep browser open after closing last tab. I changed the boolean parameter "browser. tabs. closeWindowWithLastTab" to "false" but the browser still closes with closing of last tab.

What else is required ?

My Yahoo IMAP account in Thunderbird no longer has any email showing in the Sent folder. There's plenty of mail in Yahoo Sent mail in the browser, but it's not finding its way into Thunderbird. I tried the Repair option, but I just get a typical message that I often see for Yahoo:

"The current operation on 'Inbox' did not succeed. The mail server for account Yahoo responded: [SERVERBUG] UID FETCH Server error - Please try again later."

The Yahoo account shows Sent mail in my iPhone. The Thunderbird Sent folder was seeing messages as recently as last week, so this seems to be a new problem, and I don't know if it's something that I did wrong by mistake. Thanks for any help.

I'm having trouble using a particular site, that I used to be able to in particular clicking on sub menu's from a context menu if that is the correct term, meaning I cannot click an item/button to reveal a menu below it. From the image supplied there are 2 'menu's' with a < character that when clicked should reveal a sub menu of items, works in Edge/Chrome etc.. the only extension I have is Keeper.

Am using 115.10.1 Thunderbird on Windows 10. This email account inbox shows one unread message, but I can't find any unread message. Toggled message threads to see if a previous message was unread, but could not find any there either. Have both closed Thunderbird and restarted the computer, but it made no difference. It is bothersome, but my main concern is whether this is indicating some virus or other hack of my computer. This is just a home computer, not on a business network. Do have it on wi-fi. Is it just a matter of somehow resetting the unread message indicator or is it a sign of something more serious?

Checked everything. Not sending after upgrade. Is sending in troubleshooting mode.

No add-ons.

Not anti-Virus or firewall issue because I shut them down. to test. With both on it sends in troubleshooting mode.

I have spent many hours combing thru possible solutions.

Please help. TIA.
