I saw this post https://bugzilla.mozilla.org/show_bug.cgi?id=542690 where it seems implied that it should work, but on LMDE 5 w. firefox 98.0.2 64-bit scrolling horizontally w. touchpad doesn't work for scrolling on pages nor for scrolling the tab list at the top.

Hey folks, hopefully you can help with this mysterious issue!

I've been running Firefox successfully on my Windows 10 PC for a long while now. Last night, for some reason it simply ceased to work. New windows and tabs would not load any content. I also couldn't access the Settings at all (clicking on Settings in the browser menu produces no results or feedback.)

Yesterday, I had Firefox open all day (I usually have my computer on all day), and it was working fine. Around 8 or 9pm, I first noticed that none of my open tabs were loading any content, and the tabs had the "loading" animation playing. New tabs would also not load any content. I assumed it was an internet issue as I did see my internet connection get disrupted once or twice. I did not see anything (apps, etc) on my PC updating.

This morning I found Firefox was still not loading anything, although my internet connection was fine. I tried opening Chrome, and it ran just fine. Everything else that it is internet or cloud based on my PC is running fine too. So it seems to be an issue just with Firefox.

I have listed my steps to troubleshoot below, but I want to note one weird thing I observed: Even when Firefox is closed, and Task Manager doesn't show any Firefox processes open, my PC seems to think Firefox is running. For ex. while trying to uninstall Firefox or delete certain files, I would get a warning to "close Firefox first" or "can't perform this action while app is running." After seeing these, I would again confirm that Firefox appears closed and Task Manager shows no related tasks.

My PC build: - Windows 10 Home, 64 bit - Version 20H2 at start of issue (updated to 21H2 during troubleshooting) - OS build: 19044.1526

Things I have tried for troubleshooting already: - I have WebRoot on my computer due to my job, and I asked our IT staff if they could see WebRoot blocking anything related to Firefox on their end. They said it was not. - Used "Firefox Refresh" - Uninstalled and reinstalled Firefox - Cleared app cache / app data - Updated Windows from 20H2 to 21H2

I 've used Thunderbird for several years without any issues - thank you for that - but suddenly, over the last two or three weeks when sending a message, I have been getting an authentication error message from my ISP and the e-mail is rejected. This occurs every time I try to send an e-mail after rebooting my PC.

A password change made no difference.

Incoming messages are not affected.

Clearly my ISP is blocking the messages because it is not receiving the correct password or account name - but why?

The workaround I have discovered is to enter troubleshoot mode, then send the e-mail (successfully). Then I can exit troubleshoot mode and any later e-mails are also sent successfully - until I reboot the PC and then I have to repeat the procedure again.

I am using v91.7.0 (32 bit) on a 64 bit PC and running two e-mail addresses, both of which exhibit the same behaviour.

I do not have any add-ons and I use default preferences.

Any help would be appreciated.

v91.7.0 on OS X 10.14.6 Used TB for many many years. Have a Charter IMAP email account set up. All of a sudden a good number of months ago, all my emails in my Inbox have a banner that says "This is a draft message" when just clicking on them in the email list.

Opening any of those mail (which for some reason always opens as Write: mode, whatever that is, not view or reply; not sure what's going on there either) will show a yellow banner at the bottom of the email with the following: "A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity <IDENTITY> <MY EMAIL>."

Any other folders, like Sent or Saved folders don't show or have this issue. I am not and don't use Unified View. I also have two GMail accounts and neither of them are doing that with their Inboxes.

EDIT: It displays some similarities as the bug here, but not all of them (https://bugzilla.mozilla.org/show_bug.cgi?id=1508153). For example I don't get a double window.

I got a surprise in TB email this week. When I'm writing a message, the Edit function appears to be corrupted both when I click Edit and when I click on the text I want to edit. No cut, paste, etc. functions appear anymore. What happened? How do I fix this?

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 think this happened after the recent update to 91.7.0, may have been 91.6.0. I lost, at a minimum, an entire folder. Doing a filtered key word search, Thunderbird shows that the folder, thus the e-mails in in that folder, are in Account NONE. How do I access this account so I can move the e-mails back where they belong? C:\Users\3TIER\AppData\Roaming\Thunderbird\Profiles does NOT show a "None" profile in any of the sub-folders

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?

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?

thanks for any tests/insight into what might be causing the issue

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
