Hello, I've just set up Thunderbird on my IMac OS Monterey version 12.2.1 and have synchronized my gmail account. However not all folders have migrated. What is causing this and how can I fix it? Thanks!

This problem appears on MacOS 10.13.3 but NOT Linux Mint 19.3 (Tricia).

Repeat-by:

1. Start here:

       https://www.cnn.com/

That page should load cleanly.

2. Now click on "Live Updates", which is the top entry in the middle column of that page, and as of 3 April 2022 11:20 AM EDT takes you to:

       https://www.cnn.com/europe/live-news/ukraine-russia-putin-news-04-3-22/index.html

On MacOS, that page loads and is momentarily visible; then the page/tab it's loaded in goes blank. On Linux, that page loads as expected and remains visible.

Notes:

The problem did not happen with Firefox 88.0.1/MacOS.

The problem does not happen with Firefox 98.0.2/Linux, i.e., it appears to be specific to MacOS.

The problem remains whether extensions are enable or disabled (one a time or all at once).

The problem remains after the cache has been flushed and pages have been reloaded.

The problem remains after Firefox has been (completely) shut down and (cleanly) restarted.

The problem does not happen with Chrome/Chromium on either MacOS or Linux.

The problem also happens on *some* other pages on CNN's site (but not all) and on *some* (but not all) pages of other sites but there doesn't seem to be a pattern that explains which URLs exhibit it and which don't. This suggests that it's not privacy settings or extensions or anything like that, because there's no reason for those to vary from page to page within any one site.

If I'm VERY fast on hitting the "X" that stops a page loading/rendering while in progress, and I get the timing just right, I can catch it before the page/tab goes blank. So it appears that Firefox is in fact fetching all the content and can render it, but then for some reason is blanking the page/tab once that's done.

The attached screenshot shows what the problematic page (from step 2 above) looks like on Linux. On MacOS it's blank, so I didn't include a screenshot of that.

i recently lost my computer to destruction. i have a number of files saved by Mozilla backup on a thumbdrive. i have several backup files dating from 2014 all the way until now. after re-installing Firefox on a new computer, i tried MozBackup to restore my old Firefox from the latest file dated a coupla of months ago this year. the files have names like Firefox 16.0.2 (en-US) - 2013-01-05.pcv or .pfc. when i tryt and load it into backup it saysit isn't a valid backup file. how can i get this to work?

I upgraded from Thunderbird 52 to version 91. Even though all the account settings appear to be correct, I can neither send nor receive mail. What the -- is wrong?

I appreciate that Thunderbird has client-side adaptive Junk filtering. I believe the target audience for this is primarily those who don't filter their own mail. Unfortunately for those of us who do filter our mail, this feature takes priority over other filtering.

Specifically, I'm using Sieve (IMAP/Dovecot) on the server to control filtering, but as soon as mail hits the Thunderbird client it's re-processed. I don't mind if my filters ultimately don't filter some mail item, where it ends-up in the Inbox. Then Thunderbird adaptive filtering may help "adaptively" to flag something that gets through.

Can we do something in Thunderbird to only allow adaptive processing on the top-level Inbox?

As an admin I have just created scripts that will forward mail to me when another user manually moves mail to Junk. This email is dropped into a specific folder under my Inbox so that I can process it with new rules, bans, or even to let the user know that they should simply unsubscribe from that specific list. But most of it is indeed Junk. I don't need adaptive processing to identify it as such, and I don't want my email account profile to adapt to someone else's Junk.

I can set a header for Thunderbird if it would only use that as a "do not use adaptive filtering on this item".

Is there a developer API into this process? Anything else to hook into it to get more control over it?

OR, do I and every other user that uses this server need to turn off Thunderbird adaptive filtering? :(

Thanks.

My windows 10 took a powder and had to have it repaired The thing that i may not be able to get are the add ons and the address book that i had on it they are installing anew hard drive but were able to back up some of the files and such. I know it is something about address book and history but not sure how to do it .i and when it comes back can i come back and get help

For years I’ve had no difficulty accessing online my HSBC bank accounts in UK using Firefox. In recent days they have changed their security access method whereby their site now requests a security number generated on one’s phone using the HSBC App (it used to be a random number from an HSBC supplied handheld device) which then has to be input via my Windows 10 PC to access my data. If I use Microsoft Edge as browser, everything works fine, but when I try Firefox my system just hangs after I’ve put my bank ID into the HSBC opening page (the first security step) and simply never opens the next HSBC page which would ask me to generate the said code on my phone. Seems a browser related problem. Any ideas why Edge works but Firefox does not?

Hello, I have the question while using Firefox.

When I browsing the websites via Firefox, I found that Firefox uses two groups in keyshare(x25519,secp256r1), while other browsers use single group(x25519) in the keyshare. So I tried to find where I can set up keyshare part in my Firefox, but I cannot find it.

Can you explain where can I find the setting for the keyshare in the Firefox?

Thanks!

I am trying to use a new HP Spectre laptop which will be my all purpose home computer. I selected Firefox Browser as the default browser but I don't believe it has ever come up as my browser. It is loaded among many other apps (?). I used to call them programs (?). I get Edge, Chrome, Bing, and others, none of which I want or ask for. They just seem to appear randomly.

Which Mozilla version is the latest which includes ((update options )) I still use windows 7 32 bit My system is not compatible for 10 The new version makes trouble with window 7, so I uninstalled It goes crashing when opens I read many topics using old version does not solve the problem For me it solves When I install new version ( 90 or newer ) it shows black screen when opens But with old versions, it does not show --- Now I tried 75 it contains option but the update still runs though I have chosen Check for updates but let you choose to install them

Hello,

I use Thunderbird for all my email addresses, have for years. Never had an issue until today. I've been offline all weekend and have not received an email to any of my addresses since 04/29, 3 days ago. Is Thunderbird down? If not, how can I fix this?

Thank you

This has been going on for about half a year. Often when I try to comment on Reddit there will be a glitch in which text cannot be written or eddited notmally, such as:

• the new words being typed are now suddenly being typed at the front of the comment and are replacing the old words as I type
• if I click to the end again it might also replace these lattermost words when I type
• pressing backspace to delete words may leave the same characters but the blinker will move back through the letters as though I was simply pressing the left arrow key to move back
• backspace does nothing
• writing is impossible

Firefox is up to date

(I would upoad a short video but I cannot)

Thunderbird usually performs very well for me. Although sometimes a new email is received showing a weird timestamp that is obviously incorrect. As an example, right now the time of day at my location is 1:18 EST. So far, my received emails today have times ranging from 5:03 am to 1:16 pm. Except for one. It shows today's date but 5:31 pm. A time in the future. If I look at that same email on my iPhone, it displays a more acceptable time of 9:19 am.

This started occurring about 2 months ago and happens about once a week. All from spam. So this is no big deal but I'm curious why. Does anyone have an explanation? Thanks, Reeka

Hi, Please bear with me, I understand very little! In 2012 the business I work for was taken over by a new boss. The previous one set me up with a new email address which he set to be used with my gmail account.

My new boss wants to move clients but my email account is not included in the addresses she wants to move. Her email addresses are showing up on Eclipse. My email address/account isn't there. The previous boss was using Thunderbird. Is my email account there? Or does it need added to Eclipse?

I have no idea how to access or log in to Thunderbird to see if my address is there?

How do I find out who is hosting my email account?

I have no idea if I have explained this properly. I access my work email through my personal gmail (POP, IMAP???) but have no idea where it really "lives"!
