Right side bookmark column pops up when Firefox opens. I close it, set setting to horizontal (which is also always present by choice), but the right column return search time I open the browser. I have poor eyesight and need all the screen I can get.

How do I keep it off?

am a senior and need to talk to someone about not being able to open certain important websites - like for my credit card. Most other website cause me nor problems. At 82, and with poor eyesight, the articles are just mumble/jumble to me.

Been using Thunderbird for a number of years but recently the SSD on my laptop became corrupted and I had to buy a new one and install TB and restore my profiles from a backup.

I have two accounts and switch between them with Profile Manager.

The new laptop is an ASUS Vivobook with Win 11 Home and although TB runs ok the first time, if I close the current session and try to open the other account, nothing happens when I click on TB icon on the taskbar. IF I wait for around 5 minutes then it will run

Checked in Task Manager and cant see any instances of TB running, so any thoughts on what's wrong. Does not matter which order I open the accounts.

I had a working thunderbird/gmail connection until my main drive went to SSD heaven. Yes, I have current backups but I took the opportunity to move to a Win 11 box so all my data is safe but might be in different places.

I can log into gmail but can not configure thunderbird to do that. The Account Hub does what it is supposed to and all is well up to Password question. The gmail password does not work and I can't remember ever giving thunderbird a password. My mozilla accounts all refer to a domain that I gave up 5 years ago,

Any suggestions would be very appreciated.

Since about November 2025, all the mails I try to sent to @sfr.fr addresses (different recipients) fail and I get the following message: Sending of the message failed. An error occurred while sending mail. The mail server responded: <xxx.xxxx@sfr.fr> recipient domain rejected (blacklisted by local policy).

Please check the message recipient "xxx.xxxx@sfr.fr" and try again

I did not have this problem before. If I use Greenby's web mail (My email provider ), the messages are sent without any problem. I would very much appreciate some help to solve this problem! P.Y: pemy@pemyoung.plus.com

I have followed the instructions that several people give to transfer my existing Thunderbird installation to a new computer where I have just installed Thunderbird. That is I copied the Thunderbird folder and put it in the Roaming folded found in %appdata%. Both computers are on Windows 11. When I open the new Thunderbird, it does not recognise it. Furthermore, in Help>Troubleshooting information>Profile folder when I click to open the folder, it looks for a folder that is not in my previous Thunderbird installation: qr19mupe.default-release instead of the one that came with my imported Thunderbird folder. Has this happened to anybody and found the solution? Can anybody help please?

I want to create a wireguard file that I can load onto my router to permit me to use mozilla vpn on my router as i will be using it on static devices eg TV which I want to connect through the router. I understand this can be done but the syntax offered does not seem to work on my PC running win 11.

I have upgraded to TB153.0.3ESR. I've been on the ESR stream for a long time now. But recently, I started having trouble with my google calendar appearing. I've deleted the provider plugin, I've moved to OAuth2, and for the most part, calendars that I have that are read-only from google show up all the time. But my personal read/write google calendar will not show up.

If I go in and delete the cache.sqlite file, and then start Thunderbird, my entries show up. However, if I switch to a different week, my read-only calendars still show up, but my personal calendar goes away.

I've tried everything listed in all of the steps to fix this, but I can't find anything that gives a clue as to what is happening. Anyone else see this?

Steve.

When signed in Firefox puts popups on the right of the screen that refer to my incoming mail. I end up having to delete them all the time. How can I prevent these popups?

Recently I had to install a new windows, and I signed in to my Firefox account and found all the data from the previous windows including the open tabs, I could find them from "Tabs from other devices".

But now can't find them any more, although that device name is still there in my account page, under " connected services", please advise.

Firefox version: 153.0.4 / Windows 11 25H2 26200.9168

Attached are images showing the performance settings and the active extensions in case any of them proves to be responsible for the problem.

Yesterday I noticed a horizontal screen tear when scrolling down through sites like X(Twitter), YouTube, GMail, Reddit etc. I immediately checked my performance options and they were deselected. I activated them again, but this did not solve the problem, I also tried to active some layers in about:config but those were already activated. Checked Nvidia settings too, vsync is on, Edge is not affected, Chrome is not affected, even installed Waterfox to see if only Firefox-based browsers are affected, but that one was OK too.

Last resort was to refresh the Firefox installation from the uninstall utility. After the refresh and all settings/extensions got auto-reinstalled, the screen tear got fixed. I left the PC running over night and when I accessed Firefox again this morning, the screen tear problem was back. However, now, the performance options are disabled, and if I try to enable them and restart Firefox, the options get disabled again.

Would really appreciate it if anyone could provide a solution that does not involve refreshing Firefox daily.

Hi, Need help with maps that cannot be removed. Thunderbird downloaded my map configuration, after a new Thunderbird installation, from my online account/my internet provider which was OK. After that I removed all maps on my online account but the maps in Thunderbird is still there but out grayed and I cannot delete them?

I uninstalled Thunderbird and also removed Thunderbird associated maps under %AppData% and %LocalAppData% but when I do a new clean installation same maps shows up in Thunderbird again? I waited some days and did a new installation again, but same issue. I have also deleted everything in W11 cash memory.

Attached picture shows the out grayed "NyMapp and subfolders" I cannot delete. How do I get rid of those folders?

Any help is appreciated.
