Bug: Inconsistent font rendering (text alternates between serif/sans-serif, bad kerning) in certain PDF
Status: REOPENED
Priority: P3

This seems to happen with all PDFs published here: https://www.opn.ca6.uscourts.gov/opinions/opinions.php.

This bug is reproducible in Nightly build 20211217212339.

Steps to reproduce:
1. Open the PDF at https://www.opn.ca6.uscourts.gov/opinions.pdf/21a0287p-06.pdf (archived copy attached) in the built-in viewer
2. View page 5 (the issue is present on all pages, but is most obvious in the main text of the document)

Expected behavior:
The PDF renders normally, with only the serifed font and consistent kerning, as happens in Chrome and macOS's Preview.app.

Actual behavior:
Text alternates between serifed and sans-serifed fonts, and text that appears sans-serif has very inconsistent kerning.

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

For clear see attached gif.

1. Click to start near address bar for open «Add Bookmark» dialog
2. Expand tag list (you must have multiple tags that do not fit all the way into the tag list, so a scroll bar appears)
3. Scroll tag list so that your target tag is not at the bottom and the scroll bar is not at the top.
4. Click to target tag to select it.


Actual results:

The tag list scrolls in such a way that the target tag is at the bottom of the list. This is very annoying when you need to add several tags in sequence (especially if they are next to each other in the list).


Expected results:

The tag list must not be scrolled through.

Bug: Allow disabling remote tabs in the Urlbar without disabling them elsewhere
Status: VERIFIED

Results matching the search term are now interfered by sync.
What previously appeared as normal results now are "overwritten" by sync items.

So instead of seeing normal items I get items with blank favicons as well as the URLs being removed and only show "Firefox here: <Device name>".
So they're double reduced. I can't quickly find a site's item by favicon, nor can I see the url. The title is there, but of course it might be nondescript. And there's usually zero indication of the website.

I upgraded from FF88, so I don't know when this happened, but it's quite a hefty issue.

On 88 I sometimes saw device tabs, but they seemed to be additional items. And not this local item butchering nonsense. Also, even for those I don't recall the favicons becoming blank.

I see no purpose use for this at all. I want to find an item quickly, I don't care that it was already opened on a device that I'm not even using. 
I do use synced tab through the sidebar when I want to continue browsing what I started on mobile.
Bug: Stop clearing browser.ctrlTab.recentlyUsedOrder when migrating the pref (was: browser.ctrlTab.sortByRecentlyUsed set to false when upgrading from esr78 to esr91)

Created: 2021-12-19 20:34:31+00:00

With bug 1692303 and bug 1701542, browser.ctrlTab.recentlyUsedOrder was renamed and flipped to false,, except if ctrl-tab was detected as having been used... through a pref that was added in bug 1687703, which landed in 86. So people who were using ctrl-tab in esr78, and then upgraded to the next esr (i.e. esr91), see the pref reset because they had no occasion for the browser.engagement.ctrlTab.has-used pref to be set.

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

1. bookmark a page, say, it's "bookmark 123"
2. open bookmark sidebar and type "bookmark". I'll see "bookmark 123" among the items listed
3. Right click on it, edit bookmark, rename it to, for example, "bookmark 111",  and save.
4. The bookmark on the sidebar is still "bookmark 123"


Actual results:

The bookmark name doesn't change to the new name. I have to re-search the term, "bookmark" in this example, to see that the name is changed to "bookmark 111".


Expected results:

The bookmark sidebar should change the name after I'm done renaming. I'm sure it's the behavior of older fixfor version.
Bug: Dropping an URL on the Firefox content area defeats the purpose of the kiosk mode
Status: UNCONFIRMED

Created: 2021-12-20 06:58:09+00:00

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

1) start Firefox with the '--kiosk' flag ('-kiosk' under Windows) in order to enter the locked kiosk mode
2) press 'ctrl+f', 'F3' or other keyboard shortcut in order to open the search field, quick search filed
3) type an URL in the input field
4) drag that URL and drop it on the Firefox's content area


Actual results:

URL gets immediately opened by the Firefox


Expected results:

Firefox should never open a dropped URL when working in the kiosk mode.

The input fields work effectively as an address bar defeating the purpose of the kiosk mode.

Is there any preference/policy/source code modification which we could use to disable 'opening of the dropped URLs' feature entirely in Firefox?

I have attached a screenshot which demonstrates the problem.
Bug: Long menus lost their scroll arrows and automatically scroll to the bottom.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

1. Using the bookmarks manager, add many bookmarks to the 'Bookmarks Menu' so that the menu will be higher then the screen height.
2. Close the bookmarks manager and open the 'Bookmarks' menu from the Firefox menu bar.


Actual results:

1. The drop down menu is missing the scroll arrows (top and bottom).
2. Any mouse movement over the menu automatically scrolls it to the bottom.
3. Trying to access menu items at the top of the menu using the mouse's scroll button works, and the menu do scroll but then issue (2.) happens.


Expected results:

1. Long menu must have scroll arrows.
2. Long menu shouldn't scroll to the bottom due to mouse hovering.

Those issues do not accrue in nightly 97.0a1 (2021-12-19) (64-bit).

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

I upgraded my computer and installed the latest Firefox.  This moved me from 95.0.1 to 95.0.2.



Actual results:

I have tried in vain to find any controls to display the bookmarks sidebar and to manage the hierarchy within that sidebar.

I don't know whether the situation I am facing is a bug or a request for enhancement.  I don't think it can be the latter because the previous version worked fine.


Expected results:

I expected either:
(1) the relevant icons/buttons etc for the bookmarks sidebar, or
(2) some way of finding out that there is a new way of doing the bookmarks organisation.
N.B. I have something like 50 bookmarks in my 95.0.1 version and cannot manage with just a single horizontal strip.

2. Open a bookmark that is associated with some container "B"


Actual results:

The bookmark is loaded in the currently focussed tab which is then switched to container "B"; the tab history from before opening the bookmark is lost.


Expected results:

The tab history not to be lost: either, by having it preserved (and switching container if you move back to it) or opening the bookmark in a new tab.

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

1. I have a bookmark folder containing a number of bookmarks (8), all of which are for hosts which are associated with a defined container
2. I select "Open All In Tabs" from that folder in the bookmarks menu


Actual results:

Firefox opens 16 tabs, 2 per bookmark in the folder.

(My theory, and this is just a theory, is that it opens each bookmark in a new tab, which is the default container/not contained, then firefox determines it should be contained and so spawns a new tab accordingly, yet also replaces the current tab with a container tab as well.)


Expected results:

Firefox should open 8 tabs, one per bookmark.

4. Click the download SVG button or download PNG button in the bottom right.

Expected:
The dialog has labels and radio buttons are selected by default, etc. as normally happens when downloading a file.

Actual:
Chaos ensues, resulting in no labels or icons being shown and no radio button being selected. Basically a ghost dialog. See my next comment below for a screenshot.
