I was connected to O365 with my work email but cannot send any message. IMAP works just fine, all folders synced regularly, but sending not work for some unknown reason.

SMTP setting is as follow: smtp.office365.com port 587 STARTTLS OAuth (this is correct setting, all others shows errors, including outlook.partner.cn & smtp.office365.cn, which is completely normal since I'm not in China).

The first thing that jump out is that my password is not OK, which is not correct. Password is OK. Click on "Retry" or "Enter new password" do nothing, just return the same pop up. If "Cancel", then receiving message with "unknown error 80004005" and all other blablabla about unknown reasons, with instruction to check my SMTP settings.

I've tried all variations available, but nothing works. Sometimes, at some moment after click on Cancel, it said "Message sent" and I can see it in my Sent Items folder, but it's fake because I never receive that test message to my personal Gmail address.

I have already tried all suggestions I could find (deleting passwords, resetting all, restarting, deleting and adding account again, changes in Config editor related to security.tls), but nothing worked for me.

My OS: Win 10 Pro, build 2004, TB version 78.3.2

Any advise is very welcome. Thank you all in advance.

Gmail is going to require OAuth 2.0 sign-in SFAIK, that means I will no longer be able to access gmail with Thunderbird. Are there plans for Thunderbird to meet the OAuth 2.0 requirement?

Read support article about importing username and password info direct from .CSV file. I see at the bottom of that article that if no such option presents (Import from file), I am to ensure that signon.management.page.fileImport.enabled is set to true. I don't see that operator within the listing of configuration options. I can create that operator and set it to true, but that doesn't make the 'import from file' option appear in the three dot drop down menu within the Logins and Passwords page. Has the title or location of the fileImport operator changed, been moved?

Firefox displays pdf files very nicely, but how do I save the file to my download folder?

FF help says this is done by “clicking the download link” but I cant find any download links anywhere in the FF GUI, when the pdf is displayed.

I'm sure its there somewhere, but I just cant find it..

Help appreciated,

Cheers, Lars Bo

Firefox has been saving images from some sites as webp instead of JPG for a long time. There have been repeated threads on this subject which get locked and then pushed into the long grass.

Sure, I could botch a solution by installing an add-on to convert them, or I could use something like XnView (which I do, periodically, and in bulk) after the save event has happened, or I can edit about:info to tell Firefox not to accept webp - but this breaks functionality for some sites (like eBay), but I have found that in the end I have had to start switching to Microsoft Edge to do my browsing for a number of sites because Mozilla Firefox are ignoring repeated user requests to provide a simple option to STOP doing this.

I don't want to save any files as webp - save them as PNG if you like, or jpg, but I use an ancient copy (v3.24) of ACDsee (from the days of Windows 98) for my image browsing, sorting, viewing etc because it is perfect, blisteringly quick, has no extra editing or other functionality which I don't need or want, and it doesn't bloat up anywhere with thumbnail files... but sadly webp didn't exist back then so it doesn't support it. I have used a number of much more up to date browser-viewers, but there is nothing can touch this OLD version of ACDsee for basically brilliant design.

I'm not changing my image viewer. It's non-negotiable.

I WILL however change my web browser if I have to, if the developers of the browser continually kick into the long grass to lock, hide away and pretend there's isn't an issue which has been repeatedly flagged as an annoyance for so many users.

I have been using one form or other of 'Mozilla' family of browsers since the days of Quarterdeck Mosaic. I don't particularly want to switch my loyalty, especially to Microsoft, but if they are listening to what customers want and providing it, and Mozilla are not, what else is there to do ?

I am a retired systems developer. I cannot envisage this being SUCH a big ask.

Modern software treats its users like idiots and takes away control, doing everything it's assumes on their behalf that they will want.

It is not difficult to provide an option within settings for when saving webp files to save as webp, png or jpg with conversion if necessary. All you need to do is hear the screams and respond. :)

I'm trying with utter lack of success to configure a Thunderbird install to link to a Gmail account via IMAP.

System Basics: Windows 10 Home, 64bit, fully patched. Antivirus by MalwareBytes 4.30 Premium, fully updated. No fancy firewall, just a regular router.

This account had been installed and working fine until a family member "helpfully" changed the Gmail password, but reauthentication fails. I enter the account details, including password, into the Thunderbird Accounts settings for the account; it pings Google and correctly retrieves all the IMAP settings, and when I click "Done" Thunderbird opens a browser window to Google's two-step authentication with the email address prepopulated. However, when I click the blue "Next" button on that authentication page, rather than advancing to a password screen, the browser simply deletes the email address from the text box and stays on the same screen (see attached image for what I'm talking about).

Things I've tried:

• Uninstall, reboot, reinstall Thunderbird.
• Turn off MalwareBytes protection.
• Uninstall, delete every registry key related to Thunderbird, reboot, reinstall Thunderbird.
• Clear cache on every browser on the system
• Change Windows default browser settings to either Chrome (see below) or IE/Edge
• Install new browser (Chrome wasn't yet on this PC), then change Thunderbird's file handler for https to Chrome (this is MUCH harder than it used to be as T-Bird v. 78.anything doesn't have the old "Preferences" menus)

Incidentally, changing browsers doesn't seem to make a difference in that pop-up browser window, so I suspect Thunderbird is using its own internal browser and not the system browser.

I have, and can send, the support info extract from T-bird to a support technician but am unsure of uploading it here. Nevertheless, I welcome suggestions ... this is driving me nuts!

All things I try to download on Firefox are extremely slow compared to other apps like Steam, torrents and other apps. I get 90mb/s on the download speed checks, but when I try to download something on Firefox, it downloads at like, 120 KB/s.

dear ladies and gentlemen,

Firefox has been delivered with the new print dialog since version 82.

I have to print around a hundred PDF files at work (usually only the first page of the document). The new print dialog means that there is a lot more work for me here.

Is it possible to set the "old" system print dialog by default or to instruct firefox to always print only the first page of the document by default?

HERE IS THE ANSWER Here is the answer to get TABS BELOW with Firefox V90 . . copy all of this code below the broken line into your - userChrome.css - file and save it. You can modify the 45px in this line if you wish to get an appropriate height . . just experiment with different numbers till you get it right --menubar-height: 45px; /*30px|41px=11px; caption buttons on menubar*/

Also to make the tabs wider or narrower, modify the line which is coded width: 50vw !important;

Finally you must enable - css - in Firefox, by typing about:config into your address bar, and search for toolkit. When all the toolkit options appear change the one which says toolkit.legacyUserProfileCustomizations.stylesheets to TRUE by click the icon in the right hand column. Than close Firefox and reopen, and check how it looks This will enable your - css - file to be read, and interpreted and accepted by the Firefox browser.

Windows 10 gesture two finger swipe left and two finger swipe right doesn't work in Firefox. Two finger swipe left allows user to go history backward and two finger swipe right allows user to go history forward. These gestures work in Firefox if the user hold Alt key and preform the gestures. But most of the users don't like to hold Alt key and preform the gestures. Please fix that issue.

Currently, I'm using Firefox 82.0.2 on Fedora 31. Recently, it's started opening most, but not all links in a new window instead of the current one. Not on all sites, but most. As a pair of examples, it opens links to articles on gasbuddy.com in a new window but not on Slashdot, and until a few months ago, it only opened a new window if I right-clicked and selected New Window from the context menu. I'd like to get the old behavior back, as this is quite inconvenient.

Users have been complaining about update nags for several years, and when a solution is found via about:config, Mozilla typically puts a spanner in the works and deletes the relevant config items like 'app.update.silent', 'app.update.doorhanger... etc.

I just want to remove the popup, not the ability to update. I'll update when I'm good and ready, and I don't need a popup each and every day nagging me to do so.

If Mozilla must ape Chrome, then aping Chrome's non-nagging update policy would be a good move.

FF 85.0.2

Hello, I have trouble getting sound playback on firefox (checked 85.0 and 78.7.0esr both 64 bit) on windows 10. I checked sound on youtube, and netflix. I checked other applications like spotify and mpv, and soundplayback there is fine. Also it works on Firefox nightly (87.0a1).

What i have already tried: - restarting my computer - opening windows volume mixer and see if firefox is muted - updating my audio driver - different playback devices (Device over HDMI and Line out) - reinstalling firefox - uninstalling firefox, delete folders in C:\Users\$username\AppData\Local C:\Users\$username\AppData\Roaming - new install with fresh downloaded installer - restart to safe mode

Since firefox nightly is working i suspect that maybe the application name "Firefox" is muted somewhere. This could explain why i can reproduce my error on ESR and stable but not on nightly.

Thank you for your help in advance

I would like to enable ESNI and bypass ISP watchdogs. So I prefer to keep ESNI on. After last update I'm not being able to access about:config. It shows an error.

What's the issue here, if anybody could help I'd be much obliged. Thank you.

Gmail will not load in Firefox, but will in Chrome. I've cleared my history, cookies, and cache. I made sure I had the latest Firefox update, restarted my computer, checked in internet connection, everything I could think of. There is no error message; it just stops loading and the page is totally blank, as you can see on the attached image. I've run out of ideas and know-how. Anyone else had this issue and resolved it?

My system requires me to log in to the internet when I start up. Usually I am given a message and asked to click on a link, which brings up my login page. Since yesterday I have been receiving the following message: 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." I have cleared my cookies and cache and restarted numerous times. This message keeps coming up. I am able to access my home page, but any attempt to click on bookmarked links results in this message, and occasionally it will refuse even that, telling me it's redirected me too many times. Apart from clearing my cookies cache, which doesn't help, what else can I do to fix this problem? Thanks
