Good day, I am using Thunderbird with my Office 365 e-mail account. I like pretty much the appearance of Thunderbird, as it is not so crowded as Outlook. Unfortunately very frequently it is "Not responding" and the screen freeze for few seconds. Should wait untill returns to normal condition itself, to continue my job. I did not found any topics into help about that problem and any solutions. With Outlook I do not have the problem described above, but prefer to use Thunderbird. Kindly ask you for any advices, if available. Many thanks in advance!

As of last week, I am unable to reply in the reply sidebar in a Slack thread. When I click the reply icon associated with a comment, the sidebar opens and a loading icon is displayed for a second but then nothing happens; all I get is a white sidebar. I have updated to 99, shutdown and rebooted, opened Slack in an new window and nothing allows replys. I am running Windows 10 Pro, build 1903, 64 bit, i5 processor, 16 GB RAM. Suggestions?

hi, I follow some suggestions as

https://support.mozilla.org/en-US/questions/1309622

and I try to delete mimeTypes.rdf and handlers.json but Thunrderbid continues to use chromium to open https links.

Can you help me?

I can't send out any emails all of a sudden. I'm getting the following error message: "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtpauth.earthlink.net failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again."

Please advise.

After firefox update to 100.0 - i can't use any of my addons, and cant install new one. All my current updates appears in "disabled" status, and there's no "enable" button. I have many addons, so it's the global problem.

Also, i can't install any of updates from addons.mozilla.org, i get message "Installation aborted because the add-on appears to be corrupt". All addon xpi files are downloaded without problem using "save as", also, after clicking "install" on addons website i see download progress.

Please help to resolve this issue!

I am running TB 91.7 in Win 10, with Bitdefender AV and firewall. When attempting to send an email, I received a popup indicating an issue with the SMTP outgoing server. (original message attached) (also original in and outgoing server settings attached). Upon checking the ISP's recommended settings, I discovered some updates (settings attached) and made those to TB (settings attached); I had to do some interpretation here, hopefully correctly. Attempted resend of message, still error messages (two popups attached). The webmail version works fine. Thanks.

Amazon 'Look Inside' pop-up does not work with FF as I've configured FF. Iv'e included a screen snip.

I've unchecked block pop-ups but still the 'Look Inside' doesn't work.

I had the same problem like the link below when I use firefox.

https://www.reddit.com/r/firefox/comments/tjxh7s/videos_freeze_when_window_isnt_in_focus/

So, did what the instruction says and it solved the problem regarding discord.

But, since I changed that setting, firefox doesn't remember my google login or dark skin settings of other websites (it was always automatically logged in when I use YouTube. Not like it remembers the password).

How can I solve it? I resetted firefox multiple times.

This issue shows up randomly, affecting a random number of messages. Issue is that one message will take over other messages following. Message notification will look normal in the inbox, but click on the message following X message, and the X message is what will appear. The subject line at the very top of the page will be from Y, but the rest of the information following will be from X. Two, three or more messages may be affected. Deleting X will make no difference. This time, four messages were affected.

I have Thunderbird set up with several different email accounts. In December 2021, one of the email accounts suddenly stopped working. It won't receive or send emails. I didn't change anything.

I'm not knowledgeable about figuring this stuff out, so I'd be very grateful for some help. The email that's not working is a gmail account. At first I was getting an error message about the password not working. I'm positive I'm using the correct password, because I tried it on https://mail.google.com/ and it worked fine.

I have Windows 10. I updated Thunderbird to 91.8.0 (32-bit) and it didn't make any difference -- I still can't receive or send email from the problem account. I didn't change any server settings (they are the same as my other gmail accounts, except for the specific account names).

When I try to get messages, it says says Connected to pop.gmail.com...

then

connection to pop.gmail.com server timed out

I have no idea what this means or what to do. If you need more information about my settings, just let me know what you need and I'll get it.

Thanks for any help you can offer. At this point I'm desperate.

1. Some of my emails display BLANK content when opened; since Thunderbird updated with 91.8.0 to my Windows 11 64bit. The header displays correctly but the view screen is blank. I've tried troubleshooting in safemode and disabled any add ons, reset all the display controls and restarted with no success to resolve the problem. I've tried different view modes, Original, Simple HTML and Plain text and still get nothing showing. I've tried to copy the blank screen to clipboard to try different color modes with no luck. Not a problem of White on White text. The message is in there when I check the Message Source, but it does not display in the view. However the original mail does display correctly on my browser when viewed on my ATT email account which forwards to Thunderbird on my computer.

ODD Solution: i just noticed that when I move the email with the BLANK content to TRASH, then that content does display correctly! Then I can move that email back to my INBOX and it displays there correctly. Isn't that crazy? Ha,ha, the quirks of computers are like quarks in quantum mechanics with random results.

2. Some of my email content is displayed under the WRONG HEADER. The email content displayed under the wrong header is usually the content from the prior message. For example I get an email from CVS ok. Then my next Email is from Citibank, but that email displays the content from the prior CVS email. No solution to that as of yet. Are these BUGS in the new release 91.8.0?

TB has been working for years with 2 gmail IMAP accounts and Google calendar. TB has just updated to 91.8 and the gmails and calendar stopped working. I deleted the stored passwords, started TB in troubleshooter mode and re-entered the google passwords.

Google calendar is now working but the 2 gmail accounts still don't work.

I deleted one of the accounts from TB and re created from scratch. Account creation fails with

 Unable to log in at server. Probably wrong configuration username or password.

The other gmail account which I haven't deleted comes up with an authorisation error after entering the google password and allowing access.

I have checked that TB cookies are allowed and javascript is enabled.

I have run out of things to try.

What I don't understand is the calendar is working but gmail isn't even though they use the same Google account and password (and Oauth2).

Firefox recently stopped playing embedded youtube videos on my phpBB forum site?

ADDITIONAL COMMENT: why don't you include a date on these posting? a lot of wasted time on old posts? and also need a 'Preview' on these before posting?

The styles look astonishingly wrong, I really think it is a problem on my end, but cant figure out how to fix it, as you can see in the pictures, text is incorrectly sized and/or justified, color gradients are also weird looking, as well as sizing of many elements and tons of other things.

I have tried to completely remove Firefox from my system and reinstalling it, that did not seem to fix it. The reason I think is is a problem of mine is because i was playing with fonts (emojis weren't working on my system,not on Firefox tho, now they are in both)

I don't think the things i did with the fonts did anything to Firefox, since this problem only showed up on Firefox, but since the problem arrived just after a reboot while I was installing and removing the fonts, I think its important to mention.

To sum up I think the problem comes from my local configuration of Firefox, I probably did not delete it all before reinstalling, I am running (Arch btw) a current version of EndevourOS.

I am using the latest Thunderbird 91.8.0.8126 and latest Firefox 99.0.1.8136. I am having the same issue as reported in these posts:

https://support.mozilla.org/en-US/questions/1343530 https://support.mozilla.org/en-US/questions/1344530 https://support.mozilla.org/en-US/questions/1350244.

I have 5 Gmail accounts that I manage for different family members. All accounts in Thunderbird access Gmail via IMAP, and are configured to login with OAuth2.

This week, Google removed Thunderbird access from 2 of the accounts, I do not know why. When I login to the accounts via the web in Firefox, Thunderbird was no longer listed under their 3rd party access. The other 3 accounts are fine.

1 of the accounts does not have 2FA enabled. I was able to re-login with Thunderbird when prompted, and I was presented with a window to grant Thunderbird access, which worked, no problem. So Thunderbird's browser was clearly recognized.

But the other account does have 2FA enabled, and that is where the problem lies. Thunderbird prompts for login, and the username and password are accepted, but when I enter the 2FA verification code, Thunderbird presents a window saying "Your browser is not supported anymore. Please update to a more recent one." (https://bugzilla.mozilla.org/show_bug.cgi?id=1677845). There is no option presented to grant access to Thunderbird. Yet, the verification did work, because my primary email receives notification that the account was logged in from a new device.

For the record, the failing 2FA account is managed by Family Link (the other non-2FA account is not). According to https://support.google.com/mail/thread/127545584/, such accounts cannot login to email clients. But that has never been a problem before, and 1 of the other still-working accounts in Thunderbird is also managed by Family Link and works just fine, so that can't be the culprit.

Also, I do have AVG installed with Email Shield enabled, but disabling that makes no difference.

Thunderbird's UserAgent is "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:91.0) Gecko/20100101 Thunderbird/91.8.0". And yes, cookies are enabled in both Thunderbird and Firefox.

Is there a way to get Thunderbird to use Firefox properly for Gmail login, instead of its own integrated browser?

Hello! I think I have tried EVERYTHING to get Firefox to stop crashing in the past 6 months. Today I am so frustrtated. Can anyone point me in the right direct. (and yes this happens with a fresh install, disabled add-ons, safe mode, yadda yadda yadda

bp-9d35ce5b-7503-4b20-894c-05b520220417

additional reports in image attached.

If you can help me...BLESS YOU!!!

Since the Firefox 99 update loading some pages (for example, the Gmail sign-in page) using Firefox on my Linux Mint machine, that I'm running a VNC remote desktop session on, results in a crash.

Crash report ID: bp-5dc1e89d-dc1f-40f2-9dbe-7f4380220419

I've tried running Firefox in safe-mode and the crash doesn't happen, but turning off hardware acceleration, swapping to default themes, removing all extensions, and completely removing Firefox and the .mozilla folder and then re-installing Firefox have not changed the crash behaviour in the absence of the safe-mode flag.

I would appreciate help in identifying what other paths of investigation I can take.

Hello, I have a GMail account, from which I download my email in Thunderbird (in Linux), and keep it ordered locally.

I noticed that my backups are very slow, because Thunderbird keeps two big directories that get updated often:

11G /username/.thunderbird/k0aa999s.default/ImapMail 7.0G /username/.thunderbird/k0aa999s.default/Mail

under /username/.thunderbird/k0aa999s.default/Mail I see I have my local folder structure and that's good, but what is under ImapMail ? I guess it is the corresponding email structure I have on the gmail server, (although gmail reports that I'm using 5.67GB, not 11GB). The 11GB are created by just 4 files: 1.6G Apr 22 09:55 Sent Mail 3.0G Apr 22 14:16 Trash 2.6G Apr 22 14:16 Important 4.3G Apr 22 14:20 All Mail

I saw it suggested to rebuild the folders in Thunderbird - I did it but nothing changed

What can I do? I dont need / want to replicate Gmail structure locally, I just want (and use) only what I have under /username/.thunderbird/k0aa999s.default/Mail

So I have installed Firefox on my Galaxy S20 Plus running Android 12. All permissions are granted and everything is working except the camera. When testing it with https://webcammictest.com/ it ask for permission to use the camera and mic. I of cause allow the use and afterwards it says: The device is not found.

I have tested the mic alone and it is working. The test site is also working in Chrome, Edge, Vivaldi and Brave. So chromium browser do not have any issue with the camera or mic. I have also tried other tests sites with the same result.

I first noticed it when I had to call my doctor which sent a link to a site with camera feedback on. I was surprised and stressed about it wasn't working. Having a doctor waiting and a sick child, while installing Chrome to get it working, was not a fun experience.

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"
