Bug: Window position preference is no longer kept on a second screen
Status: RESOLVED

Resolution: INVALID

Resolved: 2021-09-23 09:14:42+00:00

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:60.0) Gecko/20100101 Firefox/60.0 SeaMonkey/2.53.3

Steps to reproduce:

I open window like an email, a page information, history... 
I move it on my second screen




Actual results:

The next time i open the same window, it no longer appear on my second screen but always open in my first screen !


Expected results:

For seamonkey until 2.49 version, the windows always open where they were closed on my second screen !
Bug: Browser: Frequent short UI freezes on particular web pages
Status: RESOLVED
Priority: --
Resolution: WORKSFORME
Created: 2020-08-08 10:36:26+00:00
Resolved: 2022-01-04 02:34:29+00:00

I'm experiencing frequent UI freezes with Seamonkey (if memory serves me right since ~ version 2.49), e.g. when loading a new website, entering an URL in the URL bar, while scrolling on a website or even multiple times while typing this text.

In all of those cases CPU usage increases to 100% on one CPU, stays that way for maybe 2 seconds, and the complete UI is frozen during that time (though events will be processed once it normalizes again). My impression is that this always happens when an opened website is using a lot of JavaScript.

Steps to reproduce:
===================

A good example is when visiting Kickstarter (even when doing so with a fresh profile):
* Visit https://www.kickstarter.com
* The Seamonkey logo in the upper right corner will freeze for about a second, together with the rest of the UI
* As soon as the site is loaded, click on one of the categories (e.g. "Games").
* This time, Seamonkey will freeze even longer

Older Seamonkey versions or the current Firefox version keep reacting during the whole time. My impression is that Seamonkey will be permanently slower even when closing the tab after that.

I'm not sure whether this is platform specific - it is happening for me both on my openSUSE and Slackware Linux PCs, but I don't have a Windows or Mac PC for comparison.

Bug: Accelerators to tag messages are not shown in the Message -> Tag menu

In the support newsgroup, it was pointed out that the accelerators which can be used to tag messages are not shown in the Message->Tag menu in SeaMonkey Mail&News, but do appear in Thunderbird[1].

This menu seems to be built in mailWindowOverlay.js, in SetMessageTagLabel(). While in SeaMonkey this function sets the accesskey attribute, in Thunderbird it sets both accesskey and acceltext. See bug 781466 and the related commit[2].

Bug: Unable to select folders/directories with the XUL file picker
Status: NEW
Priority: --
Created: 2020-08-25 16:39:45+00:00
Resolved: 2021-08-12 21:47:26+00:00

In SeaMonkey 2.53.3 on GNU/Linux, with ui.allow_platform_file_picker set to false (so that the XUL file picker is used), I can't save two or more files at the same time.

There are at least two ways to reproduce this: in Mail&News by saving two or more attachments at once and in the Navigator Page Info dialog Media tab, also by saving two or more items at the same time.

This may have been introduced by bug 1335539, where the use of wrapDOMFile in nsFilePicker.js was replaced with createFromNsIFile[1]. This seems to fail silently when the file picker is used to choose a directory. Adding a catch() to these promises, I get NS_ERROR_FILE_IS_DIRECTORY.

If I'm understanding the code correctly, CreateFromNsIFile in dom/file/File.cpp calls FileCreatorHelper::CreateFile in FileCreatorHelper.cpp, which calls CreateFileInternal, which calls CreateBlobImpl. This last one calls InitializeChromeFile in MultipartBlobImpl.cpp, which will fail for directories (line 360 for 2.53.3 final).

GTK3 themes may use a background image or gradient instead of a background color for tooltips. When using such a GTK theme with the SeaMonkey default/classic theme, the combination of foreground and background colors can result in unreadable (or hard to read) text in the feed preview header, which is styled using tooltip colors.

2.49.5:

- I close this (newest) tab and the browser returns to the original tab from which I opened the link

2.53.3:
- I'm opening a new tab from some link
- I close this tab and the browser switches to the tab on the far right, browser doesn't return back to the tab from which I opened the link

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0 SeaMonkey/2.53.3

Steps to reproduce:

Only about 15-20% of the websites with videos that I visit, the video controls will not work when I click on them.  You can start the video but, after it starts I can't fast forward using the sliding bar at the bottom to another part of the video.  When I click on the "stop" button, it won't stop.  When I click on the "full screen" icon it will not go to full screen.  I tried to figure out what video player the sites are using and have been unable to figure out it.  I believe it started in the version before 2.53.  I hoped it would be fixed before version 2.53 came out.  However, the controls still are not working on videos on certain sites.  It seems that some sites changed overnight.  The videos work correctly and the next day the controls don't work.  The videos controls work correctly on Firefox, Chrome and MS Edge but not on Seamonkey.


Actual results:

Searched the web for answers and found none.  None of the video controls worked on a few site with videos.  Tried the same sites with the videos on Firefox, Chrome and MS Edge and they all worked fine.


Expected results:

The video controls should work on all sites as Firefox, Chrome and MS Edge does.

Bug: View Image error on canvas
Status: RESOLVED
Priority: --
Resolution: FIXED

Clicking "View Image" on a Canvas (which probably the same time is a frame) produces an error:
```
Error: TypeError: Argument 1 is not valid for any of the 1-argument overloads of URL.createObjectURL.
Source File: chrome://communicator/content/nsContextMenu.js
Line: 1127
```
The problem is
[let blobUrl = URL.createObjectURL(this.target);](https://gitlab.com/seamonkey-project/seamonkey-2.53-comm/-/blob/2_53_4_beta_01/suite/base/content/nsContextMenu.js#L1127)
because *this.target.toBlob()* must be used rather then just *this.target* .
(And *toBlob()* canvas method is async).

Note, the correspond Fx part has [toBlob()](https://gitlab.com/seamonkey-project/seamonkey-2.53-mozilla/-/blob/2_53_4_beta_01/browser/base/content/content.js#L879)

Preliminary patch attached (fixed the issue).
