Firefox recently 'crashed' on my desktop PC. It asked me to restart in safe mode or restore to the original state. I chose to restore. This meant that I had to re-add all of my add-ons and log back into my favourite sites as my log-in details had disappeared. I got everything back to normal eventually, except for one very important site. I am now no longer able to log on to my bank website to review my accounts. I get an error message on the site saying " Log on error. You need to enable cookies in your browser to logon to Internet Banking." I have never had this problem before. I am able to log on successfully on my tablet, and also via a different browser on my desktop PC. I'm not a tech expert so this is very frustrating. I've tried clearing cookies/cache/data in the settings but no success. I really need to access my bank accounts on my desktop as I find this easier. Hopefully you can help as I don't want to use a different browser.

Best regards Andrew Sambrooks

There is one correspondent whose emails come in, flash on the screen for a second and then disappear. I find it in Junk. I've got the email addres whitelisted on my provider's filters. How can I intercept this process. It's only the one address. So far. Can I whitelist address on TB? I've got it set to not intercept anyone in my address book and this address is definitely inmy address book.

I've been using a Rewards site regularly (3/4 times per month) for several years without problem. This weekend the attached pop-up appeared. It makes no difference whether I select Resend or Cancel, the program just re-displays the pop-up trapping me in an endless loop. The only exit is to close the window and abort the process. I was able to complete the task without any problem using Edge instead so it appears to be a Firefox specific issue. I haven't consciously changed anything since last using the site successfully on 24 May. Any help/suggestions appreciated.

I have created an entry in my Personal Address Book. When I am in that address book I click on the Import tab. I select CSV file. It provides me a File Dialog to select my CSV file. But then it provides me with a File Dialog to select an address book file. The address book I want to use is the one I am currently "in" in the program. But if I for some reason I wanted to import into another existing address book, I should either have to get "in" that one, or it Mozlla Thunderbird would list the address books it knows about as a selection.

It appears I am supposed to select the file that Mozilla Thunderbird created somewhere. From a search it appears (this is on Windows 11) from the App Store that is somewhere in ..\AppData\Local\MozillaThunder.MZL_h<numbers and letters>\LocalCache\<Roaming | Local>.

I don't understand why I am choosing a file that is already open in Mozilla Thunderbird?

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?

I am using Thunderbird Supernova and am pretty happy with it. However, I cannot figure out how to specify a different time zone than the system timezone when creating an event. For example, if I just bought a flight that departs at 4PM London time and I am in Miami when creating the event, how can I create this event without having to convert that time to my current time?

Surely this is possible but I can't figure out how. Thanks for any help!

Hello, Since a couple of weeks I'm facing a strange issue on my Firefox installed on my desktop (arch linux) where the suggestions window that appears when clicking the URL address bar, is shifted upwards and covers the address bar itself and the majority of the bookmarks. Has anyone experienced a similar issue and is able to point me towards some troubleshooting steps? Thanks!

I was in the middle of generating a long "reply all" to a message and wanted to jump to a new page when it would be printed. I absent-mindedly hit Ctl-Shift-Enter and the entire window disappeared and there was nothing in Drafts! Ctl-V just restores the last thing I added to this very long reply! I had been working on this for 90 minutes, doesn't Thunderbird continually update Drafts while working on a long email?

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

I've installed TBSync with Thunderbird and my O365 calendar is now syncing.

However, my email subfolders are not fully updating.

I have a # of subfolders I've created in O365 but they aren't appearing in TBSync in order to choose them to sync in Thunderbird. I am getting some (what I would call 'standard') subfolders in TBSync to choose such as Contact, Calendar, Tasks, and some other email accounts I have 'sync'd' into O365, but none of the actual email subfolders for the O365 account itself (i.e. 2024 Financials).

In Thunderbird, the only folders I see to sync (Synchronization & Storage > Advanced)are: Inbox, Draft, Sent, and Trash

What am I doing wrong or missing?

FireFox assumes that text size is the same for all pages in a domain, rferl.org for example. That is _not_ true. If I have set size to 50% and then take a link to a page that's different and have to set size to 67% to read it, when I return to the original page, size is 67% and text is too large.

Recently I used the forgot about this site for reddit, but when I try to click on a link from either my bookmarks or from a web search I keep on getting. [The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies.]

Not exactly sure what causes this or how to fix it.

Hi Windows 10 64bits - Thunderbird 115.11.1 (but same happens with Linux Mint 21.3 Cinnamon). It is the 1st time I ask in this forum, so I hope I respect the rules... "Sometimes", in my e-mail "imapmail" sub-folders, "some" files with an added "-1" appear ("draft-1", "sent-1" , ...). They are always newer (modification date) than the file without the "-1". What are they ? Why create a "-1" that consumes space, and not over-write the existing files ? Is there a parameter somewhere in TB to avoid this behaviour (I closed TB, deleted them, but they "sometimes" reappear when I reopen TB ) ? Thanks in advance

My search box disappeared. I know about clicking the 3 horizontal lines, selecting customize and dragging the box. Actually the box is still there on the customize screen, but not in any other tabs.

Dragging a second box does nothing. Refreshing Firefox does nothing. Rebooting does nothing. Firefox 125.0.2

installed Ubuntu 2404 on my acer laptop along with Thunderbird, added gmail email to Thunderbird and it fails to connect to google for their security check.

popup when trying to login to google to let Thunderbird access gmail.

400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

I think the linux Thunderbird is broken.

I have been through this google process with Thunderbird 3 times windows 10 and 11 and once on an android phone with no problems
