Bug: Missing features in SeaMonkey 2.53 and 2.57 newsgroup Subscribe dialog
Status: RESOLVED
Priority: --
Resolution: FIXED
Created: 2021-01-24 18:24:23+00:00
Resolved: 2021-06-03 21:37:40+00:00

+++ This bug was initially created as a clone of Bug #1685551 +++

rdf code in the subscribe dialog was removed in Bug 1425962. Currently SeaMonkey and Thunderbird share the same code. Unfortunately some of the previous features are now missing after the update.

- The subscribe tree opens up fully unfolded which it didn't before.
- The column header "Subscribe" and the column selector is no longer present.
- Sorting is not possible.

We should try to bring at least some of the features back.
Bug: Replace helpviewer for SeaMonkey 2.57
Status: NEW

The help viewer is broken in SeaMonkey 2.57 because of RDF removals. It needs to be rewritten. 

Ideas are for an html based viewer windows able to either display a local copy or remote website content.
Bug: encoding is confusing and outdated, utf-8 missing
Status: UNCONFIRMED
Priority: --
Created: 2021-01-25 00:22:58+00:00
Resolved: 2021-03-10 22:03:01+00:00

Steps to reproduce:

I did edit an existing html file.


Actual results:

HTML-encoded letters like &auml; etc. were encoded with Windows-1252 afterwards.

Chancing the view of the text encoding did not have any effect. However there is the option to "save and change text encoding". But this will use "windows-1252" for "western" instead of ISO-8859-15. UTF-8 is also missing.


Expected results:

There should be the option to chose between ISO-8859-15, UTF-8 and HTML encoding (&auml; etc.) instead of "western" which just does something weired like using "windows-1252".

Bug: Support mozbuild 3.3 in SeaMonkey
Status: RESOLVED

Resolution: FIXED
Created: 2021-02-11 14:00:25+00:00
Resolved: 2021-03-09 00:31:24+00:00

Currently if you try to compile under Windows with mozbuild 3.3 the l10 packager will fail and the Lightning add-on will have an invalid id in its en-US install.rdf. This is mostly a 2.53 and 2.57 bug affecting makefiles but some of this is still in comm-central.
Cause is that defines in Makefiles used for the python preprocessor with double quotes and curly brackets are not expanded correctly. This isn't a problem for other mozilla based products because there are no similar cases left in Gecko code. Ours will go away later but need to be fixed in the interim.

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:85.0) Gecko/20100101 Firefox/85.0

Steps to reproduce:

Seamonkey starts off OK for sure. Memory usage low, lower than most other browsers on start-up.
As browsing continues, memory usage grows and grows, getting up to 500,000K, then higher, up to 750,000K or more.  Then, often crashes and freezes.
And this is when only a few tabs are opened.  The problem remains even after closing all tabs and memory usage doesn't drop at all.


Actual results:

RAM usage grows and grows, SeaMonkey eventually freezes up


Expected results:

as tabs are close, memory usage should drop.. Memory usage should not just increase for no reason

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0 SeaMonkey/2.53.6

Steps to reproduce:

When I enter a POP/IMAP password incorrectly, a subsequent re-enter of a correct password also fails.  The only way around this is to cancel the connection, then click Get Msgs, and then re-enter the correct password.



Expected results:

Transmit the re-entered password following the prompt (and not having to cancel the exchange).  I believe that without the cancel, the re-entered password is being ignored, and the original mis-entered password is being resent.  This is happening with both POP and IMAP connections.

This one seems not to be a universal problem.  I've not seen an issue when connecting to servers running Zimbra or Exchange, but I have seen it with Fastmail (which I've discovered runs Cyrus IMAP), and I believe I saw the same issue on another server that I used to use that was also Cyrus IMAP.

I'm inclined to suggest that this might be something that is specific to Cyrus IMAP.

My university uses Microsoft 365 accounts for email, and they have recently enabled two-factor authentication, which requires OAuth2 as a login method. When I setup my account in Thunderbird, there are no issues. I am brought to the login window for the Microsoft account and I can log in. When I try to setup the new authentication method in SeaMonkey, however, I receive an error message that the server doesn't support the specified authentication method, which is clearly not true since it works with Thunderbird. I have also tried to create a fresh profile to verify that there wasn't a problem with the one I usually use, but the error persists.

Steps to reproduce:

Actual results:

This issue does not occur in "Microsoft IE,Edge" and "Google Crome".


Expected results:

When a "ESC" key was pushed, candidate all conversion must disappear.
At the time of movement with a cursor control key, it must move in right or left.
In top and bottom of a cursor control key, as for one part of the conversion objects, it must be settled.
And a cursor can work freely.
"FEP" must be able to input a letter now from the place where there is a cursor

buc tracked down a possible performance problem with to 16x.10 gif icon. Gif icons will be replaced overtime with later formats so let take the opportunity to do this here first for the statusbar and menu bar icon.
The status bar icon also is 16x10 and can just be the same as the 16x16 menu bar icon.

Trivial fix so can go into 2.53.7 final release.

+++ snip +++

A broken choice of chatzilla's taskbar icon leads to a constant redrawing of the screen.

Disable ALL the extensions (chatzilla, inspector, lightning) in about:addons, and run SeaMonkey from cmdline with debug:

MOZ_LOG="nsRefreshDriver:5" seamonkey

The debug output stopped after the page is completed, until you move mouse etc., then it stopped again etc.etc It is an expected behaviour.

Then enable chatzilla in about:addons and repeat the MOZ_LOG run.

After the page is completed, the debug output still present infinitely, despite you do nothing.

The problem is suite/extensions/irc/xul/skin/images/taskbar-irc.gif icon, with size 16x10 .
It seems the code require geometry of 16x16 in this area. If you try to use png or jpg icon with another size there, it just not appear. But in the case of gif, the icon with the size of 16x10 (instead of 16x16) still appear, with a side effect of permanent refreshing of the screen (according to the debug output).

As of latest 2.53.8b1pre from 20210318, "tabs bar" in browser is now missing its controls for closing tabs, scrolling, and displaying the drop-list of all tabs - and a blank rectangle is displayed instead.

If you carefully hunt around (with your mouse pointer) the now-featureless blank rectangle to the right of the tabs, you can find some "active" areas to activate the missing functionality - but this isn't how it should look or work.

This is on my Windows 10 Pro "21H1" system.
