December 2020 Is there currently any way to disable the pull down to refresh feature? It's kind of broken in Firefox nightly (can trigger anytime trying to scroll the page), so I'd prefer to just have it turned off until it gets fixed.

On screen keyboard not working when using Firefox. It will work with MS Edge, but not Firefox. It flashes then disappears quickly when in Firefox. It worked previously, but a few months ago it quit working.

I "upgraded to V90. since then, the URL box is highlighted red/grey stripes. The robot head icon is now in the URL box and it says "Browser is under remote control (reason Dev Tools). I've gone in about:config and set all variables to False, yet they reset themselves to true every time. How do I disable the DevTools. Thanks

Can you please email the Merits & Demerits of both to me,as,I want to learn. Requesting herewith for a clear cut & Candid reply,& thanking you, Shrineevas

Suddenly, Thunderbird 78.9.0 (64-bit) Win10 is very very slow

I don't want to reinstall and have to redo all my settings - anything I can do for this?

All else works OK on the PC, Thunderbird was OK before.

Any way to back up my settings so I don't have to do all that again?

Thank you

The passwords generated by Firefox do not have special characters by default. Is there a way to have passwords generated that do contain special characters as required by many sites?

Hello, I've followed Firefox's invitation to install and update the browser on my Mac. Unfortunately the new version is not compatible with OS 10 El Capitan, my operating system, so now I can't use Firefox at all. How I do get the old version back?

Thank you, Lars

After an extraordinary amount of testing, I can conclude that Thunderbird is placing linebreaks inappropriately in emails sent from Thunderbird.

In other forum posts, I saw these described as "soft" line breaks that email clients could ignore, but in my testing, Gmail, Yahoo, Outlook/Office 365 all display these false line breaks (in both webmail and mobile apps). In fact, the only email clients that did not display these false line breaks were Outlook 2016 (Windows 10) and Thunderbird (Windows/macOS).

The issue is that Thunderbird is inserting these line breaks where the line changes in the view of the composer. This is an arbitrary line that really serves no obvious purpose, given the thousands of possible variations in screen sizes on mobile or desktop?

Toggling between sending in HTML or plain text seems to not have an impact in resolving this issue, and neither does switching between "Paragraph" or "Body Text" modes.

Example images are attached of how this looks.

Any hope for a resolution on this issue? (via Extension or correction by the developers?)

Thunderbird 78.5.1 On computer A, probably since one of the latest updates TB is not able anymore to connect to the server, I only get the error message "connection to server xxx failed"

Activity manager shows no messages at all Server xxx is on my network, connection is not blocked TB profile seems to be ok : when using the same profile on computer B, everything is working fine

• creating new account (same data as existing account) on new profile on computer A is not possible : message "Unable to log in at server. Probably wrong configuration, username or password"
• however using exactly same procedure and data on computer B, it is working !

So, creating a new account on a new profile is not possible Disabling firewall and AV : no change TB safe mode : no change Reinstalling and uninstalling/installing TB again : no change Windows safe mode with Networking : no change TB config:security.tls settings are identical on computer A and B I changed TB config:security.tls settings : .version.min to 2, 1 and 0 : no change

and .enable_post_handshake_auth to true : no change
and .version.enable-deprecated = true : no change
(all after restarting TB)

Changing TB Server Security settings : no change

I deleted the stored passwords, but after restarting TB is NOT asking for the pw's meaning TB is even NOT trying to connect to the server ?

(error messages are translated from Dutch, so possibly not identical to English ones)

I think I tried almost everything to solve the problem. It seems the problem is on the computer/TB installation, but where ? Can someone tell me how to proceed further ?

Hi, I'm using Thunderbird 68.8.0 (32-bit) on Windows 10. My work account is based off gmail. I tried switching to the dark theme- but it seems the emails themselves still appear in a white background with the dark text. Tested for plain text mails, calendar invites as well.

Does anyone know of a workaround to get a true dark mode on actual emails as well? Thanks !

This was never an issue but the last 3 months all emails from a particular sending keep getting sent to spam. I have added the sender to my contact list. I keep marking the emails as "not junk" while they're in the spam folder and they get moved into the "inbox" but the next one that comes in goes straight to spam. What else can I do to get them to stop going into spam? I would think that after 3 months the adaptive system would have learned to adapt.

I have NO idea what is going on:

• Just clicking on folders = MASSIVE LAG/HANG/FREEZE.
• Just clicking a menu icon = MASSIVE LAG/HANG/FREEZE.
• Just clicking one email icon = MASSIVE LAG/HANG/FREEZE.
• Just trying to open an email = MASSIVE LAG/HANG/FREEZE.
• Trying to do ANYTHING = MASSIVE LAG/HANG/FREEZE.

It does not start to happen immediately when program starts, sometimes 1 minute after, sometimes more. I cant point out a reason or action that leads to this behavior. If I restart the program, the problem persists. If I reboot the system, its gone.

Its the only program in my system having this behavior. Examples of what I work daily with: MS Office programs, Adobe programs, Oracle VM, Visual Studio, Blender and Unity.

I read diagonally something about Windows Defender, how to proceed with that? How to disable ONLY for Thunderbird? It's an interface problem, why should that work? Is this something else, memory leak, anything?

I love Thunderbird, using it for YEARS! I don't want to change, please help, I got loads of work to deliver! :(

EDIT: Found the edit Question on the right side of the screen (not bellow the post as expected), rearranged the text, and rewrote details so not to be confused with "internet lag".

Hello Everyone

I'm having troubles with playing some Youtube-Videos and Twitter Videos. I had to re-install my Windows 10 (64 Bit) due to some hardware-issues which are not related, and I'm having this issue since then. Here are the steps that I already did:

-Removing all Add-Ons -Starting in Safe mode - Deinstalling and reinstalling Firefox, then starting in safe Mode -Deinstalling Firefox with a tool that also deletes all Firefox-Related Registry Keys and App-Data Files and reinstalling it to a different path (other HD) -Disabling add-ons - Disabling Open264 Videocodec and widevine content decryption module (more just because of frustration^^, but I was then able to play some Youtube videos after this one) - mediasource.enabled is active (and all the other ones as well) -Installed addons (even though it didn't work with them disabled as well): NOscript( youtube videos are allowed, some of the are working), Ublock Origin, Video Download Helper, HTTPS Everyhwere, Tree Style Tab, Limit distracting sites - Updating to the newest Firefox-Version (which came out today)

Btw: on https://www.youtube.com/html5/ it tells me that everything works fine and I have of course the newest Firefox-Version installed.

Do you guys may have any other ideas?

Thank you for your help.

Kind regards,

Gabe

Good Morning

Today I had to repair Firefox and after restarting, I felt a strange scrolling sensation, it was not the normal Firefox scrolling, I even thought I had openend the wrong browser...so I went check about:config , and found some values where changed as new default values:

general.smoothScroll.mouseWheel.durationMaxMS 200 general.smoothScroll.mouseWheel.durationMinMS 50

I tought it was me the problem so I installed an older version of Firefox (80.0) in order to compare, and found a normal scrolling and those values:

general.smoothScroll.mouseWheel.durationMaxMS 400 general.smoothScroll.mouseWheel.durationMinMS 200

I think this is a mistake from devs, if i wanted to have horrible scrolling, I could just use Edge instead of Firefox, could you please bring the original scrolling back to Firefox?

Thanks

I'm getting Secure Connection Failed error on every single website I try to visit. Including sites such as microsoft.com, duckduckgo.com, google.com, etc. (Strangely, mozilla.org works fine.) Try Again never works, and Advanced - Accept risk works sometimes, but not always and if I close Firefox app and re-open it's back to the error page. I can't believe this is a common problem, so there must be something about my phone that's causing this. Android 11. Happens whether or not WiFi is enabled. What could it be?

The background color on the screen for composing a message is black, and the text is red. This happens for when using "Write" to open the composing screen, or using a template to compose. Even though the background and text during composition is black and red, respectively, the sent message is on a white background with black text. I would like the screen for composing the message to also be white text with black background and for those to be the default colors. Thank you.

Version 68.12.1 on Windows 10 I know the exact subject of the email, I have sent it to myself a month ago. I type "upgrade m1" with quote marks on the top global search bar and I get all kind of junk with the word "upgrade" that are mainly spams. If I scroll back manually I can locate the email with the same subject in my inbox. I have rebuilt the search cache already.

Any suggestion?
