Dear all, After migrating Thunderbird to a new computer with Windows 11, I noticed that Thunderbird no longer opens links in emails. When I click on a link, no browser opens and nothing happens, even though I can see on the bottom bar that it recognises the HTTP link. How can I fix this? Reinstalling the programme did not help, and I would like to keep the profile and email settings I already have. Kind regards

The tabs don't regularly sync between the desktop and Android browsers. I can manually hit the "Sync now" button on either end, and the latest tabs open don't change. Specifically I can't sync tabs opened on the Android browser to the Windows desktop browser. Clicking the button on the desktop browser does something, it switches to "Synching" with a loading throbber, but the tabs don't appear below in the list. Doing it on the android browser does nothing, it still reads "Last Synced 12 Hours Ago" on my android browser, and this is generally the number it says, more or less, whenever I attempt this.

I've tried updating the browser on both devices, and force stopping it on the android device and restarting it based on community recommendations, then reattempting to sync, and neither helped.

Other options suggested copying sessionstore.jsonlz4 from the profile folder on one device to the profile folder on the other device to transfer the open tabs (https://support.mozilla.org/en-US/questions/1404630), but the guidance to do that doesn't work on Android, as it lacks the menus referred to in those guides. I don't know how to access the session data on Android, nor could I find a guide for it.

On Sunday October 5, 2025 I began experiencing an issue with gocomics.com. I thought it was a temporary one that would resolve itself. Monday morning it was still happening. I contacted GC thinking the issue was on their end. They were unable to replicate it. They asked me to try to go to the site using the private window on FF. I was able to access it just fine. Therefore, we know it is not GC. I was also able to get to their page on Chrome.

I tried again on Tuesday. Same issues. I had already read on some forums where others were getting the same loop that I am: https://amub2c.b2clogin.com/amub2c.onmicrosoft.com/B2C_1A_GC_SIGNINSIGNOUT_POLICIES/oauth2/v2.0/logout?post_logout_redirect_uri=https://www.gocomics.com

It was suggested to try refreshing FF. I did that. Didn’t work. Gave up again for the day.

This morning, I tried uninstalling FF. Didn’t work. What else is there left for me to try?

I've previously asked this question but it has been archived without any action.

I have the current Android Firefox installed, my homepage setting has 'recently visited' UNCHECKED, but the homepage is adding all my recently, or possibly 'frequently visited' visited, pages! Swipe sideways to show even more of them. The only thing that should be on my homepage are shortcuts - things that I wanted to pin - since the specifically unticked 'recently visited'.

This is a privacy issue as well as just a bug. Please fix this urgently.

I've also put this on my review on Play store as I consider it something that needs attention...

After a re-start, my Firefox browser on a Dell laptop lost all history and has since also not been collecting websites visited. When opening a new tab, the shortcuts and recently visited websites are also gone and no longer being collected. My CCleaner recently updated itself to a new version but I unchecked the delete history for Firefox (which treacherously is clicked by default - I fell into that trap before). Happy to blame the new CCleaner but that would not explain why history is not being collected now - to me the fault seems to lie with Firefox instead. Another possibility that went through my mind: Is Microsoft sabotaging users of Windows 11 to force them to buy new? PS: Under "Privacy", "History", the setting is "Firefox will remember history", as it always has been and should be. But it has forgotten all previous history and it is no longer collecting any new history either!

After instalation Eset Smart Security 18.2.18.0 with full security browsers my Firefox is run only in read-only mode. If I will be disable option Security browser and run Firefox that's working. Next I will be enable option Security browser then Firefox starts with green frame. After close Firefox and next run then starts read-only mode. Eset Team is not fair play becouse resolving problem only disable option Security browser. So why is there an option that prevents Firefox from launching? All my portable browsers without Eset Security working without any kind of problems, for example Tor, Opera.

Hello, Attached are the messages I have been receiving ever since 6 October 2025. I've tried to read about fixing these myself, to no avail. (I mean, I can Read; I just can't fix this.) I've tried to Compact ALL folders individually. But that seemed to do nothing. (Before 6 October, the Thunderbird window would at least "flicker" a little after compact.) Trash is empty. Tried disabling McAfee AntiVirus & Firewall. And, no, this isn't happening because I'm using McAfee; I've been using McAfee since Windows XP and Thunderbird since before it "broke away" from Mozilla. They have, until 6 October, played nice together. I really like Thunderbird so I do not want to find another email client/program/what-have-you. There are LOTS of saved emails that I cannot move/copy to "save space", so...Help? Please?

Thanking you in advance, tonyg

P.S.-I am not computer illiterate. But, slow, easy to follow, non-BIOS changing, step by step directions would be preferred.

I am really really distraught right now. It took me two weeks to get the time and focus to write a long reply to a company's nice email to me. Stayed up till 2am to write it. Deliberately wanted to re-read it in the morning before sending. Gone. Nowhere to be found. I pressed "Save to draft" before closing my laptop. But not saved. This account actually has a "draft" folder, unlike most of my other accounts in Thunderbird, which I also cannot figure out and no one has helped me with.

In the first loading the share menu would only show other firefox devices until a few seconds later other options appear. Closing the menu and reopening would not have this problem so I am unable to check if it's an Android problem

When sending an email using the keyboard shortcut, the settings tell me that I can set TB to give me a confirmation prompt. Why can't I get a confirmation prompt when using the Send button? Is there any way to make TB do that?

I set TB to run a spell check before sending, and that gives me an opportunity to cancel the Send operation. But it only works if the email contains a misspelling.

Thank you.
