Bug: Quick FIlter should not begin until I stop typing the search terms

Resolution: DUPLICATE
Created: 2020-07-02 04:10:53+00:00
Resolved: 2020-07-03 02:57:27+00:00

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:77.0) Gecko/20100101 Firefox/77.0

Steps to reproduce:

I use the message search function. It might be quick search. The second one, that searches the one folder or account. 
When I type a search term to find matching messages, the search begins searching as soon as I type the first character. I have many messages so this causes a very serious performance problem. 
Essentially the system stalls on the first or second character and other characters typed are not entered, and the rotating wait symbol in the screen is spinning. 
It might be 10 or 20 seconds or more before control of the system returns to me and more chars can be typed. 



Actual results:

The search begins immediately, and the system stalls. 



Expected results:

The search begins immediately, but it should not begin until I click enter.

Bug: Superfluous text field border when editing recipient pills

Seen on trunk (80.0a1 (2020-07-02) (64-bit)) and 78.0b4 (32-bit), Win10

When tabbing around and then editing a pill, a visual glitch of double border occurs.

STR

1.) compose, add 1 recipient, press Enter
2.) press tab (sic!) twice (sic!) into body, then edit pill (in any way)
Weird, any two tab key presses in that area will reliably trigger this.
Without using tab, bug not seen.

actual result

- see screenshot, visual glitch of double border

expected

- pill border only

Bug: Conversion of mbox to maildir ignores Content-Type charset
Status: RESOLVED
Priority: --
Resolution: DUPLICATE
Created: 2020-07-03 12:44:10+00:00
Resolved: 2020-07-05 05:41:32+00:00

My inbox has some old emails that have
`Content-Type: text/plain; charset=windows-1251`
or
`Content-Type: text/html; charset=windows-1251`
instead of utf-8. Thunderbird displays them properly, and I wasn't even aware of these obsolete encodings before I tried to convert the store type from mbox to maildir. Upon this conversion all these email were completely corrupted, having all the text replaced by
`пїЅпїЅпїЅпїЅпїЅпїЅпїЅпїЅпїЅ`...
I've looked inside the converted message files, and this nonsense is actually there, so this is not a display issue, but a genuine data loss in the conversion process. Changing the default text encoding in the settings (by the way, why is it global instead of per-account?) does not make any difference.

Am I doing something wrongly? If the converter is really broken, is there a way to change the encoding for these messages before the mbox → maildir conversion?

Steps to reproduce:

V. 68.9.0 on Windows 10
The two mailing-list systems (sympa and ezmlm) are configured with the option "Reply to sender" (by default) and not to the entire list. 


Actual results:

The "Respond" button behaves like the "Respond to list" button.
In both cases (sympa or ezmlm, i not tested with mailman) Thunderbird does not behave as expected, and unfortunately (because it is very annoying) returns the responses to the entire list.


Expected results:

The reply via the "Reply" button should only be made to the only sender of the email and not to all of the list, as the configuration of the mailing-list software has been configured.

With other mailer (outlook, mail ...) is OK, only Thunderbird send to the entire list !

Bug: Icons missing from all dialogs

All the dialogs are missing the typical icons on the left.
This happens on Linux local builds, confirmed by Richard. Didn't test on macOS or Windows, but the problem started appearing today.

The icons are properly loaded when inspecting the source from the dev tools.

On Linux we're using `moz-icon`, setting an SVG seems to work.

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:77.0) Gecko/20100101 Firefox/77.0

Steps to reproduce:

This problem showed up when I installed Ubuntu 18.04.
I'm using Gnome "classic".


Actual results:

The scrollbars on the right are missing unless i put the mouse-cursor over the position of the scrollbar. Most of the time the scrollbar is too short for me to be able to find its position.


Expected results:

The bar should always be visible.
If there is a setting to correct this, please tell me.
Other apps like "gedit" don't have this problem, I only see it with Thunderbird & FireFox.

Steps to reproduce:

I could not log in to aol.com on either of my machines with the release Thunderbird -- seems they upgraded their security July 1 2020.
Upgraded to the beta version and still could not log on.  So deleted the aol account and re-added it.  Thunderbird did trigger the 2-factor authentication on aol which apparently it could not do when it failed to log in on the old account.
One 2-factor was satisfied found that my mail filters disappeared.  Seems Thunderbird create a new imap folder instead of re-using the old one.




Expected results:

#1 When the aol logon fails perhaps the 2-factor should be done?
#2 When re-adding an imap account you should have the option to keep your old files which should the default option.

68.10.0 64-bit

Right-clicking anywhere in Thunderbird produces a context menu that cannot be dismissed except by selecting an action from the context menu. The context menu also persists in the foreground when Thunderbird is minimized.

This is kind of bad since if you accidentally right-click you MUST take an action from the context menu to dismiss it.

Bug: about:support broken - about:home startup cache feature gate pref missing
Status: NEW

```
Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getBoolPref] - stack: experimentalFeatures/<@resource://gre/modules/Troubleshoot.jsm:433:26
```

This is caused by bug 1650790. Troubleshoot.jsm is looking for the pref `browser.startup.homepage.abouthome_cache.enabled` which we don't have. No default is specified so the code throws.
