I have successfully setup and installed Tbird on my new Windows 11 computer. Now all I need is to recover my contacts from the old computer's Acronis 2020 backup. How to do that and/or what specifgic file to search for and recover. I have attached a jpg of the Acronis screen.

If I go to save something from within Firefox (on MacOS desktop browser), if I try to forward delete some characters, nothing happens. I can go to the address bar and forward delete characters within a URL, but doesn't appear that I can do so in other dialog boxes within Firefox. I've verified issue persists in debug mode as well as standard mode (and just re-freshed firefox within the last day and thought that had resolved the issue until realizeing forward delete will still work in URL field, but not in firefox dialog boxes like the save as window when downloading something.

SIMPLIFY THUNDERBIRD IT IS EXCESSIVLY COMPLEX. I CANNOT EVEN SEE HOW TO MOVE MESSAGES FROM THE INBOX TO THE RELEVANT FOLDER IN MY LIST. I PERSONALLY BELIEVE FIREFOX AND THUNDERBIRD ARE OVERCOMPLEX AND NEED SIMPLIFIED. SIMPLES. WHY CANT I COPY AND PASTE THE VERSION NUMBER. BLOODY ARESHOLES . AS I SAID IT IS BLOODY OVERCOMPLEX. AT THIS POINT I AM CONSIDERING GIVING UP ON WHAT IS CLEARLY AN OVERCOMPLEX PIECE OF SOFTWARE THAT REALLY DOESN'T LOOK GOOD EITHER AND THERE IS NO OFFICIAL SUPPORT SO WILL HAVE TO LOOK FOR AN ALTERNATIVE. COMPLETE WASTE OF SPACE TOO MANY COOKS SPOIL THE BROTH COMES TO MIND THIS IS WHAT WE HAVE HERE

Using last Windows 10 install, and 153 esr.

Manually entering an address in the address bar sends it to search.

The advice from 2020 found with a search online, and in Mozilla Firefox support, does not solve the problem.

Not only is it a time-wasting obstruction for a new page to open and put the address at the top, it is a problem that the address bar can not be used as intended for manually entered addresses.

I'm guessing the problem is also responsible for the problem of clicking on a link in a program not opening it in firefox in Firefox. I have two programs setup, correctly, to open Firefox or go to the open browser when I click a link. I get a return in both cases that the browser may not be installed correctly.

I installed the browser as usual. Currently: 153.2.0esr I had 153.1 installed, however there was an unrelated (presumably) Microsoft problem and I had to restore. 153.1.0esr disappeared from my computer and online. So I downloaded 153.2.0est. However, both of these problems have manifested since updating to 153:

• Address bar does not function properly when adding a manual address.
• Clicking on a link in a program no longer opens the link in Firefox

I downloaded the full install program, as usual, and installed on top of the current install so my established profile is used. There are no major changes - except when features have become dysfunctional.

Searches online and at Mozilla support make clear these are current Mozilla Firefox issues. I can find no mention of either problem in Mozilla support.

Is there a solution to either or both of these problems in 2026?

p.s. I have no intention of upgrading to Windows 11. I also have updates disabled, however that did not stop microsoft from surreptitiously installing Snapshots and a personal A.I. app (evidence of which is in the registry which I deleted). The computer was lagging and glitching and running the disc almost constantly. So I went looking for what Microsoft had done - again - without my knowledge or opportunity to consent (or not) and found the culprits. I also found entries in Explorer directory for both features and deleted them.

I followed the instructions in the article. Creating tab groups is impossible. Dragging and dropping just rearranges the order. https://support.mozilla.org/en-US/kb/tab-groups-firefox-android

155.0.1 (Build #2016182535), 5fdfd0092780e85643e2cddc0e1b590c8b9ef860 GV: 155.0.1-20260903215306 AS: 155.0 OS: Android 15

The browser recognizes Russian on the website as English and automatically translates it into "Russian," but what it actually produces is a jumble of letters that are neither Russian nor English. Essentially, the browser is translating from Russian—which I don't need to translate, since I'm from Russia—into an incomprehensible, non-existent language. And I can't turn off automatic translation of Russian because it's not available. There's a toggle switch: "Never translate English," but that doesn't work for Russian. You can click "Never translate this site" on the website itself, but the problem is that it's for a single website. It means I have to turn off translation and reload the website every time I visit a Russian-language website. This is very inconvenient. I ask you to add an option to disable translation of an entire language, not just English or a specific website.

HELP‼

Are there any •SERIOUS• “Thunderbird” savvy computer geeks in 155.0that could help me merge “old” user profile directories from *crashed* computer to a new computer without messing up either one?🙏

i used to do this stuff (with my eyes closed) but I no longer remember if I had breakfast today and they are my wife’s files! 🤬

I have new notebook computer plus the •entire• old computer data on a USB stick.

will not download -- "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox"

I have a new windows laptop. I run thunderbird e-mail. I have about 13 e-mail accounts and numerous folders and a few address books and groups.

I need to transfer it entirely to the new laptop.

Where do I go on the old computer to copy files to a drive then go to new laptop and paste files to seamlessly accomplish this move?

I have attached 2 pics showing the accounts and beginning of the folders I have.

How do I copy/move/transfer everything?

Good evening.

I leave my windows and tabs open and turn off my computer by clicking the shut down button on Windows 10. The next day I open Firefox and all my windows and tabs come back with no problem. I've been doing this for a few years and I gathered dozens of Firefox windows and hundreds of tabs. Now that I'm finally ready to organize what I've been putting off I noticed that most of these old tabs disappeared in a very weird way. When I open Firefox it still opens all windows from these past years but it loads most older windows with a single tab and these single tabs are all in the New Tab state. I'm sure that these used to be unique tabs with content in them and not New Tabs and I'm also sure that these windows had many tabs each and not just one.

The tabs have the name "New Tab" on the tabs bar and they're gray and empty, which is what I set all my new tabs to be, so they're regular New Tabs aside from the being lighter gray than a true new tab page. Refreshing and F5 have no effect. I can't go back a page or forward because the arrows are grayed out. I can't figure out what these tabs used to be by browsing my history because they've been added to the pile sporadically over the years and are mixed with other web pages, most of which I don't want to open again, so searching for all of them would be too hard. Tab groups that only contained these "New Tab'd" tabs have also disappeared and can't be found on the tab groups list menu. If I go to "View recent browsing across windows and devices" and then "Open tabs" these tabs are shown as "New Tab" and if I click the three dots menu and select "Copy link" it copies "about:blank".

Though this is not the most specific fix, I went to Firefox>Profiles>(Profile name)>sessionstore-backups and (after making a backup) deleted all files from there except for the one with the oldest modified date. I did this with Firefox closed and then I opened it and a few of my old "New Tab" windows became real windows again with multiple tabs inside. Curiously, the recovered windows and tabs were not the most recent ones that were affected by this problem and most windows are still lost in the New Tab state.

I think Firefox has been failing to restore older parts of my session but only kind of because it still recognizes the total number of windows I had but then it opens many of them with no content (a single New Tab) and no memory (arrows grayed out).

I've always updated Firefox throughout the years and I don't know when the problem started happening, it might have started months ago and I just didn't notice because I stored the tabs and didn't look at them again until now. I also noticed that windows that were in my most recent and most used desktop instance were fine while windows in my "storage" desktops were more likely to get "new tabbed", but maybe it's unrelated to desktop environments and only related to how recent windows are and most of my newer windows are in the newest desktop, but I can't know for sure because sometimes some windows move around desktops after a PC shutdown so it's impossible to know if windows are sorted between desktops 100% by age, I think it's a Windows 10 problem. Also there have been some forceful PC shutdowns over the months due to power outages, and I have removed my drive and used a different drive with a different OS a few times, always switching with the PC turned off.

Does anyone know how to get Firefox to remember my full session and find out what these fake new tabs used to be? If not, is there a way I can restore my session to a state that it was previously like months ago? I would need something more powerful than the sessionstore-backups folder because it only helps me roll back a few weeks. I have backups from the bookmarks windows (ctrl+shift+O) but I don't think they save active open tabs. Just curious, do they save browser history? It wouldn't help me in this case as I mentioned before but it's good to know.

Thanks for your help and sorry if it's overexplained.

I have an email account that I have had for several years and I run it under Thunderbird. I have recently opened a Gmail account and understand that I can operate this under the same Thunderbird (I haven't tried it yet so expect a few glitches on the way, as per usual! There are plenty of articles covering this, so I live in hope)! Potential problem is: I have backed up my old profile account regularly and know how to do it (though I've not yet had to restore it and of course hope I never will), What worries me is that if I follow the procedure to add Gmail to my Thunderbird (and it works), will I get a single profile covering both email accounts which I will be able to back up in the way I am used to; or will I get 2 profiles including a new one for Gmail so I will need to back up both? A simple question but I haven't seen the answer anywhere yet!

I've mucked up and Email Account and whilst trying to solve it, I have found where the Return-Path: email address is listed as a very old email address that is no longer active on any server.

So I'm looking at how to update it??

Hello all, thank you in advance for your time. I've got a Lenovo running Linux (Zorin, an Ubuntu branch)

Crashes have been more and more frequent over the last couple weeks. Usually it closes only Firefox, sometimes it throws me back to the login screen, and rarely the computer crashes entirely. I've been trying to pin down the source of the crashes -- it hasn't only been Firefox, but most of the crashes are while FF is open.

THIS tab keeps crashing, as I type.

It seems to happen more often when I'm watching video.

Here are all the crash IDs within the last 24 hours: bp-dfb0bd40-4ce6-41bd-b9cb-ad0510260913 13/09/2026, 11:15 View bp-50a8400a-3439-4af4-b5c7-6e60f0260913 13/09/2026, 11:15 View bp-0893e979-6a06-40cc-ad0b-757210260913 13/09/2026, 11:15 View bp-8a1bbc36-9c1d-412c-a2cf-c4c040260913 13/09/2026, 11:15 View bp-4c97e699-dee7-470f-9f82-855760260913 13/09/2026, 11:15 View bp-4526b2af-908a-45be-89ae-293ef0260913 13/09/2026, 11:08 View bp-60af27d7-aeef-4761-b86e-7595a0260913 13/09/2026, 11:08 View bp-25b42dd1-3f54-4be4-bde7-801f60260913 13/09/2026, 11:08 View bp-e92ad4f9-b7d3-453e-8c5a-066910260913 13/09/2026, 11:08 View bp-d19f0c4c-9eb7-45d1-a7e7-978d90260913 13/09/2026, 11:08 View bp-b212719f-1daa-459c-8491-2c6cb0260913 13/09/2026, 11:08 View bp-9effc3ad-0b73-43d2-839c-805a00260913 13/09/2026, 11:08 View bp-7e5b6de1-7a84-48ad-86c0-e07510260913 13/09/2026, 11:08 View bp-271c4c4f-9f81-480a-9815-5f5bf0260913 13/09/2026, 11:08 View bp-956cef3e-25a1-4a8c-b7e1-668be0260913 13/09/2026, 11:08 View bp-92a596e6-edc8-4920-9365-6e3e00260913 13/09/2026, 11:08 View bp-6e309137-bf0a-4ee1-8ddf-492b20260913 13/09/2026, 11:08 View bp-d3eadcae-1967-4c31-856f-284f80260913 13/09/2026, 11:08 View bp-e319008d-d7e3-4354-95db-846e10260913 13/09/2026, 11:08 View bp-ce80cf98-4aad-46ee-a2a2-40ccf0260913 13/09/2026, 11:08 View bp-41734b4e-09d0-4dfe-ab7a-c74400260913 13/09/2026, 11:08 View bp-37752c09-a2ae-4f35-8ee6-62ee60260913 13/09/2026, 11:08 View bp-01aed5a5-d3da-4551-9646-eb73d0260913 13/09/2026, 11:08 View bp-0d52d173-f46d-4d5c-b723-441930260913 13/09/2026, 11:08 View bp-5a9507dd-21f3-4be3-8d68-ad70f0260913 13/09/2026, 11:08 View bp-0a5b5b7c-6400-41f7-ba67-c881b0260913 13/09/2026, 11:08 View bp-2ff2f687-e231-4ac5-925a-fde060260913 13/09/2026, 11:08 View bp-1c9a1836-3ebe-40bd-ac76-182850260913 13/09/2026, 11:08 View bp-f4bbc332-be5c-48f7-8e6e-c008a0260913 13/09/2026, 11:08 View bp-807e438c-9bb1-4056-b67b-48e870260913 13/09/2026, 11:08 View bp-b422a84c-4096-4ab8-926c-d63030260913 13/09/2026, 11:08 View bp-9740f00f-a1ac-4fce-96b3-704940260913 13/09/2026, 11:08 View bp-0a571a75-602f-4802-98df-22ee30260913 13/09/2026, 11:08 View bp-5f7a41ac-f92a-42b3-96bc-6dda70260913 13/09/2026, 11:08 View bp-d81a88f6-3da4-4e15-8669-352390260913 13/09/2026, 11:08 View bp-324a6102-496b-4724-9deb-3532f0260913 13/09/2026, 11:08 View bp-40969791-0669-4158-abd6-b57230260913 13/09/2026, 11:08 View bp-7b5c8e37-6cfe-4027-9bd1-fc0d80260913 13/09/2026, 11:08 View bp-62dbac62-1feb-47a6-be53-bd8b10260913 13/09/2026, 11:08 View bp-9197029c-0719-4294-bc37-e7f320260913 13/09/2026, 11:08 View bp-941d7f54-5b2e-4783-83f2-66c330260913 13/09/2026, 11:08 View bp-00202476-8680-4295-8a76-a97db0260913 13/09/2026, 11:08 View bp-027dfa8e-f3e1-44e9-a405-1ae350260913 13/09/2026, 11:08 View bp-369f58c9-4456-4578-977e-49cfe0260913 13/09/2026, 11:08 View bp-78c25147-3a9c-4ad8-9210-eb0ca0260913 13/09/2026, 11:07 View bp-f1f4b2b3-0885-4259-8dd3-bfa700260913 13/09/2026, 11:07 View bp-72d20621-92ea-417a-b063-deba40260913 13/09/2026, 11:07 View bp-721a4c72-ab3c-4ea0-8428-72b6d0260913 13/09/2026, 11:07 View bp-ffb02689-cb96-48e2-ab89-1c7f10260913 13/09/2026, 11:07 View bp-407b7ac2-8d4c-404d-974a-96d790260912 13/09/2026, 0:37 View bp-9decd8ef-b380-4bfe-8264-6841b0260911 11/09/2026, 22:40 View bp-c9a8eae8-8723-48ba-aab0-48db10260908 08/09/2026, 22:57 View bp-e0ac525c-a6c7-4af5-abe8-0ab5e0260913 13/09/2026, 11:16 View bp-91be494d-2e41-42b7-9330-e49630260913

I've never had Secure Connection Failed warnings before, but now I am getting them often. I don't want to stop using Firefox, but it seems I can get to these sites via other browsers.

I can't see bookmarks on the RH menu but only on the LH when I click 'manage bookmarks. How do I move the bookmark folders so that they appear on the RH. This happened at the last software update.

I have recently closed my yahoo mail account, removed all traces from Thunderbird, but when I start Thunderbird, after a few seconds, I get a Yahoo sign in screen over the top of Thunderbird
