Firefox Support Forum

Signed in here with email but Firefox on PC still has old email address. Tried adding new email to PC via the secondary email in accounts as nothing showing. Then a message appeared account already registered. What I am trying to do is change the PC email address to the new address which I used to sign in to Community. Any assistance would be appreciated.

I run Firefox in Ubuntu 18.04.4. Sometime yesterday audio went away in Firefox. I still have audio on Chrome. I have tried disabling add-ons, clearing cache (including cookies), resetting Firefox back to default, and have checked my preferences, Nothing works. What is next?

I want to make Firefox my default browser and I have follow your instructions, but Microsoft Edge does not give the choice of Firefox. Can you help?

Problem: videos do flicker. Especially visible on youtube with static background. Flicker is only present when video is playing, it doesn't flicker when video is stopped.

It doesn't flicker in safe mode. However, disabling every single addon and plugin I have and using default theme does nothing. Nor does enabling or disabling hardware acceleration.

What is this secret magic that safe mode have and unsafe mode doesn't?

Firefox 76.0.1, Ubuntu 18.04, Nvidia 440.82

UPD: figured out that this is happening only and every time when bookmarks toolbar is present O_o

Old subj was: Firefox 74, 75, 76, videos flicker when not in safe mode, tried everything, nothing helps

PS: how do I break a line here?

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!

when Firefox is closed and a link is clicked, firefox opens with 2 windows, one with the link location and one with my home page. This happens without fail, so when an email with a link that I want to open is pressed with the app closed. It doesnt happen if Firefox is already open. This has been going on for months, I have reinstalled OSX Catalina to see if that was the problem but to no avail.

Does anyone have any ideas

Hello everyone,

Is it possible to control Firefox 76 on Linux from D-bus ? I listed all available services with "qdbus" utility, but there is nothing like firefox/mozilla. Also, I browsed source code, and I saw D-bus support seems to be there. Thank you

From a non-programmer who used Chrome a lot until recently:

If I hit Cntrl-H like I would in Chrome, I get a frustratingly limited view. Why does it not show timestamps? So I spend time searching and find out about the Library window, and Control+Shift+H. Okay, so that's at least making it possible to see timestamps. Typing this right now, I don't remember if I had to manually add a column to see timestamps, but if I did Jesus Christ. I nearly installed some other software (MZHistoryView) before finding out about Control+Shift+H, just to see timestamps.

Also, every time I press the awkward Control+Shift+H hotkey, it resets the view to "Today". I don't know why it wouldn't default to "Just keep scrolling for as many days as you want". If I search for a specific site immediately after opening the window, then it includes entries for more days than just today. But before searching, it cuts off my view to just today. What's the point of that? Who would want such a restriction as the default view?

I've been finding this a lot lately. When I try to open a file in firefox the dialog box opens but the OK button is inactive. Example I opened in firefox https://az276020.vo.msecnd.net/valmontproduction/webforge-documents/webforge_brochure_frp.pdf?sfvrsn=520f4893_4 When I click on the download arrow in the upper right the dialog box opens but I can't save or open the file.

Since the latest Mac OS and Firefox updates, Firefox only shows the word "Firefox" on the menu bar. File, Edit, View etc. are hidden. How can I restore the menu bar to default view for ‘Firefox’?

So one of the recent FF updates caused the list of websites that I used to have to disappear. All my most visited sites are gone. In its place is a smaller list of the "topsites".

How do I get my old list of most visited sites back?

I keep getting a security warning/unsafe website. Several times I have received warnings when I tried to sign petitions and when I tried to enter the local library web site that the site was unsafe. Why? Th´local library web site?!

Recently my every time I open my browser, my home page (my email provider - Yahoo) requires me to log in instead of remembering me. I understand this may because I updated my Firefox to version 76 in the past few weeks. Please help. Jim
