User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:100.0) Gecko/20100101 Firefox/100.0

Steps to reproduce:

I set the new option "Web site appearance" as Light

. Background of "Please enter primary password" menu
. Background of auto-filled user name and password menus
. Background of elements in a bookmark folder
. Background of Downloads menu

Bug: "refresh your profile" deletes all multi account containers.
Status: NEW
Priority: P3
Created: 2022-05-06 18:53:10+00:00
Resolved: 2023-05-23 16:39:12+00:00

Steps to reproduce:
* Have multi-account containers set up with lots of different containers
* Firefox now offers a "want to refresh your profile" type thing. Hit "yes."

User expectation:
* Some kind of "clean-up" has happened

Unexpected behavior:
* All multi-account container setup is gone.

----

Discussed in slack with danny conlin, :jld and :tanvi
*  It's noted that there's https://bugzilla.mozilla.org/show_bug.cgi?id=1549204 which covers this problem
* For now, can we change the way the "Refresh Firefox" works so that it doesn't touch the privacy.userContext.enabled pref?
Bug: Firefox logo changed to PDF logo for some users after update to Firefox 100
Status: NEW
Priority: P3
Created: 2022-05-06 20:21:16+00:00
Resolved: 2022-10-17 16:00:04+00:00

In the German Firefox support we already got reports from three users that the Firefox logo on their desktop changed to a PDF logo after the update to Firefox 100.

The release notes mention: 

_New users can now set Firefox as the default PDF handler when setting Firefox as their default browser._

Maybe it's related to this work?

[Tracking Requested - why for this release]:

While it's not causing issues for using Firefox it seems pretty bad that it's more difficult for affected users to recognize their browser.

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:100.0) Gecko/20100101 Firefox/100.0

Steps to reproduce:

I have the "System Theme - Auto" enabled in my Firefox appearance settings. This issue occurs when the dark variant is used. (Regardless of whether due the system-wide dark toggle or directly using the Firefox dark theme.)


Actual results:

When selecting text in the address bar the text selection/highlighting is invisible. Occurs when using either mouse or keys to select text.

In the attached files, you can see how selected text looks in the light mode versus the dark mode.


Expected results:

The text selection should be visible.

Actual results:

My menus and context menus previously had white text on a red background.
Firefox 100 has made the text black on the red background, see attachment.
The menu bar and tabs have stayed with the white text, as they were on v99.

Note that the red background remains unchanged by the upgrade


Expected results:

The menus and context menus should have remained white text on a red background.

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:100.0) Gecko/20100101 Firefox/100.0

Steps to reproduce:

I am using eclipse to develop an application using JSP. I have selected the firefox developer edition in the web browser section to be the default browser.


Actual results:

When I try to run a JSP file using run as server, the JSP file only opens on firefox developer edition if it is closed. Otherwise, it does not open. And even after opening the browser casually, the firefox developer edition does not run the JSP file. I also tried restarting the tomcat server, but it does not work out. 


Expected results:

Whenever I click run as server on a JSP file, it should have opened on the selected browser no matter if it is open or close. And even if I try to run the JSP file multiple times, it should have opened in a new tab each time.

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:102.0) Gecko/20100101 Firefox/102.0

Steps to reproduce:

I'm using firefox nightly 102.0a1  on mac os 11.6. Since version 101 I have a problem with the prepopulated value in the find bar in private tabs. 

Steps to reproduce:

- open private tab and cmd+F to open the find bar and search for "foo"
- go to another private tab in the same window and open find bar.


Actual results:

- The find bar is prepopulated with the last search term from a non-private tab


Expected results:

- Instead the find bar should be prepopulated with "foo", as this is the term I last searched for in the private window

This problem might be related to the recently fixed https://bugzilla.mozilla.org/show_bug.cgi?id=1525350

Bug: "loading bar" makes opening a local PDF very slow

STR:
-download a large PDF (I used https://fabiensanglard.net/gebbdoom.pdf)
-try opening it locally
-opening it is slow (around 6 seconds) and a progress bar is shown

It seems the viewer does almost nothing during 6 seconds except showing the progress bar and triggering vsync: https://share.firefox.dev/3M2bDCg

Commenting line 858 of `toolkit/components/pdfjs/content/web/viewer.js`, (https://searchfox.org/mozilla-central/source/toolkit/components/pdfjs/content/web/viewer.js#858) responsible for showing the initial loading of the document (not its pages), brings the loading down to around 1 second.

An other clue of this: loading the PDF in a background tab also takes way less time than if the tab is in foreground.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:100.0) Gecko/20100101 Firefox/100.0

Steps to reproduce:

(1) I have been using the theme "Blue Mozilla Firefox" from Author "karoglan" for over 5 years
(2) All this time, I have always used this theme in combination with a light environment, to my satisfaction
(3) Starting v96.0 (up until the latest current version), I am being deprived of this light environment
(4) A dark environment is being forced onto me across Firefox, as follows:
. Background of main drop-down menu (Containing "Sync and save data", "New tab", "Print", "Settings", etc)
. Background of right-click menu (Containing the refresh icon, "Save page as", "View page source", etc)
. Background of "Please enter primary password" menu
. Background of auto-filled user name and password menus
. Background of elements in a bookmark folder
. Background of Downloads menu
. Background of Print menu
. Background of "Clear all history" menu
. Background of "Find on this page" menu
. Background of "You are about to close X tabs" warning menu
. Colour of title bar for "About Mozilla Firefox" window, when the window is not currently active


Actual results:

(1) As recommended by contributors, setting "browser.theme.toolbar-theme" value as "2" appears to fix the issue as long as the current Firefox window is open
(2) Now, the issue is that whenever Firefox is closed and and re-opened, it fails to recall the value of "browser.theme.toolbar-theme" and always reverts to "0"


Expected results:

(1) Firefox should correctly remember the value defined by users (in my case "2")
(2) Users should be given the freedom to set this value as per their convenience, regardless of whether:
. Firefox "thinks" that the theme is best suited for a dark environment ("What Firefox thinks" and "what users want" should not be mutually exclusive conditions)
. The theme is still being updated by the designer (I find this theme perfect and do not wish to be told to select another one)
