Hello, I have trouble getting sound playback on firefox (checked 85.0 and 78.7.0esr both 64 bit) on windows 10. I checked sound on youtube, and netflix. I checked other applications like spotify and mpv, and soundplayback there is fine. Also it works on Firefox nightly (87.0a1).

What i have already tried: - restarting my computer - opening windows volume mixer and see if firefox is muted - updating my audio driver - different playback devices (Device over HDMI and Line out) - reinstalling firefox - uninstalling firefox, delete folders in C:\Users\$username\AppData\Local C:\Users\$username\AppData\Roaming - new install with fresh downloaded installer - restart to safe mode

Since firefox nightly is working i suspect that maybe the application name "Firefox" is muted somewhere. This could explain why i can reproduce my error on ESR and stable but not on nightly.

Thank you for your help in advance

This is less of a question than it is negative feedback.

The new print experience allows me to enter a page scale, but it removed the previous ability to pick a page scale from a drop-down. It also closes as soon as the print is compete, retaining the manually entered scale.

Here's my old process: Load the page that needs 70% scale. Set the scale from drop-down. Print. Return the scale to 100% from drop-down. Close. The next page does not require any special attention, it will print from a single button push.

New process: Load the page that needs 70% scale. Open "more settings." Remove hands from mouse to type in 70. Print. Next page now requires undoing the first. Open page that needs 100% scale, open "more settings", remove hands from mouse to type in 100. Print.

The old process took 3 extra clicks. The new process takes 6 extra clicks plus moving hands to the keyboard. Talk about a "first world problem!" Nevertheless, there was no need to take something that was working well and make it less functional.

• At every time when I open my Laptop with Firefox for searching anything at first Bing is on,

Please show me the way how to kill that Bing Search Engine

I want to delete some bookmarks and a folder or two. I followed the instructions in the Help about How Do I Delete A Bookmark, but nothing happens, they just stay there. So, please don't tell me to go back to that page, I've done it MANY times now. There's getting to be so many obsolete bookmarks it's a mess.

When printing PDF document from web site using Firefox part of the left text is cut off. I have tried "Fit to Page" and shrink to 90% and still have issue. I can print this web document with Edge with no problem. This problem just started in the last several days. I am using Win 10 professional on a Del Opti-Plex 5080.

With the new v85 of Firefox... for Microsoft Print to PDF...

the defaults for print headers & footers has changed and is no longer available to edit or even view. It seems as though my settings remain in place for other printing options like my physical printer but even there the options are not editable or viewable.

There used to be a "page setup" option but I have not be able to find this anywhere anymore.

I'm assuming that it has to do with the bug fix for pdf printing but doesn't seem that it should be an intended outcome of the fix.

Any work arounds anyone knows about or has found?

Firefox colour addon removed the whole existing theme, replaced everything with it's default selections.

I use a custom theme, I just want to change the text colours on the menu bar, tab bar and bookmark bar. But the color addon destroyed the whole theme when I made any single change. I had disable and enable the theme to restore it. How do I import the theme to color addon so I can edit it?

The new version of Firefox doesn't have tabs like it used to. Now, I have to click a number, then click a different tab, etc . It is unusable and clunky. Are you going to put back the tab control like it was before?

I'm trying to take off this "Extension (Tabliss)" tag on my url. I have followed the instructions down below from another Firefox support forum: https://discourse.mozilla.org/t/make-addressbar-text-extension-name-of-the-extension-shorter-or-hide/28026/3

The instructions I followed are listed below:

"Users can apply custom style rules to modify Firefox’s toolbar area by creating a userChrome.css file. This takes about 10 minutes so when you have time to take it slowly and carefully:

(1) Set up your chrome folder and userChrome.css file following the five six steps in this article:

https://www.userchrome.org/how-create-userchrome-css.html 45

I have a boring video there if you like demonstrations.

(2) This is the code to paste into the file. You can edit the file using Notepad or a better editor. Make sure to keep it in a plain text format with a .css file extension (not .css.txt).

See improved rule down in: Make addressbar text "Extension (Name Of The Extension)" shorter or hide

/*
   Hide Extension Name in the identity area unless
   hovered for half a second (updated for Fx80)
*/
#identity-box.extensionPage #identity-icon-labels,
#identity-box.extensionPage #identity-icon-label {
  visibility: collapse !important;
  transition: visibility 250ms ease-in-out;
}
#identity-box.extensionPage:hover #identity-icon-labels,
#identity-box.extensionPage:hover #identity-icon-label {
  visibility: visible !important;
  transition: visibility 250ms ease-in-out 500ms;
}

(3) Firefox should read the file at its next startup and apply it to every extension page you load."

Edit: So, yeah, I need help getting this tag off. I'm new to Firefox so it could be something obvious I'm missing. I have also tried CTRL+SHIFT+R to reload the page for changes and also closed and reopened my Firefox entirely.

Thanks in advance.

Before you reply, look at the last lines if you do not want to make fools of yourselves (by answering a question that was not asked).

Two or three years ago, a number of people complained about the lack (loss of possibility) of removing many login/passwords entries. I believe you could do that a few years back, before the infamous Lockwise.

As of today (14 Feb 2021), you have to delete unwanted entries ONE BY ONE, confirming each with a click. Typically designed for tablets and phones, forgetting that the desktop-rest-of-us still can use a keyboard shortcuts and such.

For example, if you want to remove cookies that relate to SITENAME, you just have to go to the Manage Data section of cookies, type in SITENAME, select all, then remove the selection. Done in 1'.

Currently, solutions that are still recommended are:

- reset the key password, hence deleting ALL passwords - remove the logins.json file

I do not want that, because (as for the requests I have seen on this topic https://support.mozilla.org/en-US/questions/1276054), I have around 950 logins stored in there (yes, been using firefox for more than 15 years, and Netscape before that).

So, no, I don't want to remove everything ; no, I do not want to spend even 30' clicking.

Last time Firefox updated, I managed to find information online about moving the website tabs so they were below the bookmarks instead of at the top of the screen. It was a huge pain-in-the-butt to do.

After a recent re-install, the tabs have moved themselves back to the top of the screen and nothing I do seems to be able to move them back below the bookmarks.

Is there a way I can move the tabs that doesn't involve spending hours hunting through posts on the web, changing hidden Firefox settings, and recoding .css files?

If not, why do you not give the option to move the tabs wherever the user wants? Especially when it makes far more sense to have the website tabs directly above the website being viewed, at least in my opinion?

I'm currently using Firefox 85.0.2 (64-bit).

I've discovered that in my Users/UserName/AppData/Local/Temp folder, there are thousands of files eating up space with name "cubeb-shm-#####-#####-input" and "cubeb-shm-#####-#####-output", where "#####-#####" is a 10 digit number seperated by a hyphen.

I did a basic google search for these filenames and found several articles that talk about how firefox uses these, and normally creates and then deletes them, so there should only ever be one of each (input/output) file at a time. For some reason, I have thousands of these files, and they are eating up hundreds of Gb's of space on my hard drive. I only discovered this because my computer notified me I was running out of space. I manually deleted them, but I don't want to have to do this regularly, since it seems it's not expected behavior for Firefox.

I'm running the 64 bit version of Firefox 85.0.2, and there are no new updates available at the time of this writing. I'm really hoping someone can help me figure out how to get Firefox to appropriately manage these files. Help me Firefox community! You're my only hope!

So I've disabled Firefox updates because of the personal preferences. It keeps nagging me every day with the modal to update. How do I disable this annoying useless feature?

Firefox 85.0 on mac os.

I've tried searching "about:config" for all preferences that contain "update" and look like timers and changed the timestamps to something in the far future. Still no dice, the update dialog keeps appearing every day like clockwork.

Latest update blocking website like indeed from loading in information about employers and other sites too. Every update makes firefox worse. I started using other browsers because now some video's don't work either. Last thing I saw was a QUICK pop-up that said something about bits of trackers now being blocked. Well lots of things are being blocked and making browsing a miserable experience. I tried using the standards system in options. Can't find anything to make it work. Allow lots of things and nothing is working except to probably make the web browser more vulnerable to creeps. Please undo your current update and stop making so many updates. I've had three in the last two weeks and every time they screw up the browser more and more. Just stop it!

I had so many problems with it, I went through downloading different "session save" add-ons, I know what solution you guys will give me, I've done most of the posts' instructions, this is more of a complaint post.

When Windows boots up and you had Firefox open before you shut down last time, it will open anew, automatically, with your previous session, but it's on the end of the list of things that launch on startup.

Forgetting you had it on and clicking the browser again, will open a new session with the home screen instead of the previous session, then when actual session Firefox launches it's a 50/50 whether it will be in home screen as well, or actually in your previous session. Now here is the fun part. If you close the new window with just the home tab, that will now become the latest session, so your previous one will be deleted.

How to get around that? Move your home tab into your session instead of closing the window, it works 100% of the time... But can we, not start a new session if you close the home screen, or if you close just 1 tab it doesn't count as a different session. I dunno, just throwing ideas out there.

Hope this reaches those with the same issue, or people in positions to fix the issue, if anyone wants to use session saving add-ons, I took fancy to Tab Session Manager and Easy Session Manager, though not perfect, I don't advise for over 150 tabs.

I'll try to be as active on this thread as I can be, thanks for reading through! :>

I loaded Firefox onto a new Win10 laptop yesterday and made it the default browser (against the "recommended" Edge). Today some websites are loading very slowly (e.g. PCMag home page takes 30 seconds to load). Some https sites load normally and others are slow. I refreshed Firefox, did not fix it. Is there something I can do?
