Array.length remains the same even though array has element index greater than length set: Bug or feature?

I don't really know if this is a bug, or a feature of Firefox's JavaScript core engine. Say I have an array:

var array = [];

I set the length of the array to a very large number:

array.length = 155555555;

This now turns the variable array into an array with 155555555 blank slots. If I then do:

array[502039410402] = 5; // Notice that 502039410402 > the previously set 155555555 for length

array.length remains at 155555555, but the actual array is appended with a sudden index 502039410402 (i.e., index 155555553, 155555554, and then suddenly index 502039410402; see screenshot), with that element containing 5. Is this a bug, or an intended feature?

I would appreciate it if anyone could let me know.

Thanks!

Crash at startup if Firefox not properly quit before shutdown Debian Buster

Hello,

One of my last Crash ID report : 49e3c347-5deb-4659-b9d1-281b00200514

I experiment this problem on two of my computers. Both are running Debian Buster. If I don't forget to quit Firefox before shutting down my computer, then I believe I won't have problem the next time I switch on my computer and launch Firefox.

However, as most of the time, if I shutdown my computer with Firefox still being open, it seems that Debian Buster doesn't close properly Firefox. In fact, if Firefox was still open when I switch off my computer, I can be sure (100% of the time) that at the next startup, Firefox won't be able to launch the previous session and I'll have to "restore my last tabs".

No other software seem to suffer from the way Debian Buster switch off. Only Firefox.

Thank you for any help one could give me,

Regards, Thatoo

Good day, i met next issue with Coockes transfer during redirections (i suppose that).

I.e. when i try to download smth from Google drive i got: An error occurred during a connection to doc-0o-ag-docs.googleusercontent.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I try to follow standard advises such as disable tracking and cookies blocking (as well i disable fingerprints and all addons and delete all cookies and history storage and it's didn't help at all).

I try to download in private mod as well, but got stacked with same issue. With Chromium all works fine.

Firefox version (nightly): 78.0a1 (2020-05-28) (64-bit)

I try to download with vanilla Firefox - same result.

I have a few special buttons on my keyboard (Calculator / Mail). I've set them (on lxde-rc.xml) to run a simple bash script (Volume up / down using pactl). Unfortunately, I've noticed that only on Firefox hangs when I press these buttons (tested with terminal/slack/IDEs/Chrome, no issues). It's a ~2 seconds hang that prevents me from doing anything (tried scrolling/typing/clicking, nothing).

Any way to see what is actually happening / disable this behavior?

Given that Firefox Developer Edition isn't typically packaged by distros, the only way to install it is manually unpacking the tarball from Mozilla to some suitable location and manually write a .desktop entry. But now that the main Firefox build is available as a Flatpak, are there any plans for publishing Developer Edition that way as well?

Missing device in synchonized device list to transfer tabs

I have two computers: one personal (HP), one from my work (MBP). I quit my job a few weeks back but still had my MBP in case they needed something. I continued to use it and I had to return it back yesterday.

I synchronized my tabs using Firefox Sync on the MBP and could see them well on my HP. I formatted the MBP and returned it, without disconnecting my Firefox account. I got back home and tried this morning to load on my HP the tabs I had on my MBP, but it is not listed anymore. (Surprisingly, some other device I didn't touch for 2 or 3 weeks is still listed, even though it's not connected.) I tried on another device to connect my Firefo account, thinking it would propose me to open a session have somewhere else, but the MBP session isn't listed there either.

I can't lose all the researches I made during the last few weeks :S I turned my side project into a full time job, I need them.

Is there any way to retrieve somehow the tabs I had open on the MBP? Is there a way to get from the Sync server any copy they have for my devices? Does Firefox writes to disk what it gets when listing the data of synchronized devices, so I could try to look into the deleted files on my disk?

Help or ideas much appreciated!

I've been using Firefox on Windows for a very long time. When I switched over to Ubuntu, I kept using Firefox as my main browser. When I'm on Ubuntu and I try to switch tabs with Ctrl+tab, sometimes the the Firefox window closes and I don't get to access the previous session in Restore previous session in the hamburger menu or in history. Is this a Ubuntu problem or am I clicking on something I don't understand?

OK, I have no question that some wacky combination of keystrokes has gotten me into the issue I have, Im a poor typist at best and not really getting any better.

But Im cruising through my day and all of a sudden my Browser Linux Mint installation of V71, shifts EVERYTHING to about 1/3 of my screen width on the LEFT and leaves the other 2/3 completely inaccessible.

Rebooting doesn't help, hard shutdowns no go. I have more that 1 copy open (3 MAX), and the other 2 arent effected, just the one that was my primary.

This has occurred before and in the past it EVENTUALLY resolves itself. But Id love to know what Im doing wrong so I can NOT do it, as well as a solution?

Thanks hopefully I can post my screenshot.

I'm running a brand new install of Debian. Initially the install comes with Firefox version 68.7.0 ESR. After setting up my Firefox preferences, I tried installing uBlock origin. The install seemed to go fine, but I noticed that the uBlock button does not appear to the right of the address bar by the bookmarks/sidebars/firefox account buttons. I went on Youtube to check to see if it was actually blocking ads and it is not blocking. When I open the addons page to check if it is there (Tools > Addons) it shows uBlock origin as an enabled addon.

I opened synaptic to see if there is an upgrade version available and saw that there was (Version 68.8.0 ESR). I went ahead and installed the upgrade, but there is no improvement, still seeing ads on Youtube. I removed it and reinstalled, but also no improvement. I've been searching google for answers but other than references to the issues last year with addons being broken I am not finding anything helpful.

Any ideas on how to fix this? Your help is appreciated.

This is a problem connected with SCROLLING. There are three standard ways of scrolling , while surfing and looking through site pages: 1. Use the Mouse roller 2. Use the left click press on the mouse, simultaneously press and move the scroll bar 3. There are two Scroll bar junctions - one at top and other at base. The mouse left click button may be clicked - either in steps or on a continued click... to make the page move ... in steps or on a continuous movement.

The QUESTION here is: While we have this Last No.3 above facility in UBUNTU-Mate, such facility is not seen in UBUNTU, XUBUNTU, LUBUNTU, KUBUNTU etc. WHY?

Can we not have the same facility in the other OS too?

Is there a way I can extract all the cookies with date & time so that I can check against previous occurrences of the 4GB data movements (I have a few records).
