Firefox Support Forum

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

MacOS 12.7.5 Firefox 127.0 (64-bit)

in my tablet and phone dont the same pages load well and in the computer too before the reinstall.

thanks

I like Firefox and am using it for years, but I cannot accept lengthy loading time. I have a fast and stable internet so this is not the problem. Please let me know what the problem is and how to fix it.

I've been trying to install an add-on that is in the .zip format. I set xpinstall.signatures.required to false and restarted the browser, yet Firefox keeps telling me the add-on cannot be installed because it's not verified. Is there a way to change this?

Hello,

i am following instructions from here:

https://support.mozilla.org/en-US/kb/automatically-fill-your-address-web-forms#w_turn-address-autofill-on-or-off

but i don't see option to enable autofill on desktop. On mobile, autofill only shows USA ans Canada. Why Chrome allow me to use address autofill and Firefox not?

I have been trying to contact support about an issue regarding being able to change my account password to the page at https://support.mozilla.org/en-US/questions/new/mozilla-account/form, however I cannot seem to submit any information. When I try, the page reloads, followed by multiple uncaught errors observed in the console, including a cross site origin request block error (in the latest stable Firefox). My browser settings use the standard browser privacy setting, and custom DNS.

Regarding the error I was trying to report, I am unable to change my password, receiving "incorrect password" despite entering the correct current password. In the browser console, a POST response with error 400 is shown.

Hi. I feel like this problem has only shown up in the last couple months but for some reason, on firefox, when say watching something on youtube and I go to pause or skip around in the video I'll get this very unpleasant distorted digital noise sound very briefly. I've tried turning off and back on hardware acceleration and some other things but no dice. I can hear the distortion on my onboard sound, my usb headset, and hdmi audio through the graphics card so I don't think its my hardware. This distortion also doesn't happen with say MPC/VLC or watching Youtube via Edge or Chrome.

Hello!

I get this error often when I try to access various websites. This doesn't happen when I use Opera, so I assume the problem is not with the websites.

My OS: Windows 10. My Firefox version: 127.0 (64-bit).

With some emails in Outlook on Firefox, clicking on a link within the email gives me a new blank window, with its address line saying something like this: (name of original site, then) ".list-manage.com/track/click?u=ca38acd 82fe622b7" etc etc... This doesn't happen with all emails, but often enough and in some of my most-used sites... I'm on a new HP desktop. Can anyone help?

I can open an email or a google search for this particular website, Sundance, click on an item which then opens on my screen but Firefox is unresponsive when I click within this item screen for details like available sizes and colors. This is the only site that this has occurred.

I was wondering about password recovery, or account continuity when changing a password.

I have a new machine at work and want to add my firefox account....

After a forced shut down, my home page is suddenly blank. All my tabs are missing. All my most used links are missing. All the reading suggestions and pocket is missing.

Is there anyway to restore these items?

When using Firefox (latest) and attempting to login into a website I get an error (see attached image) generated by the host's server's firewall. It appears it thinks I'm a bot. When I use Firefox's privacy mode I don't get this error. I would prefer not to use privacy mode. I contacted the administrator of the website I'm attempting to access and he couldn't offer any help.

When I use Google Chrome browser I don't encounter the above problem. This leads me to believe it's not an issue with my Avast Anti-Tracking and Antivirus settings.

Any help would be appreciated.

This has been bugging me for ages. Happened on Windows 10 and now on Windows 11.

I start watching some video on YouTube or whatever, decide it's not useful/what I want, stop playing it, close the tab or navigate away, but if my device locks, the controls for this old, discarded video, that I didn't want to watch, are on the lock screen.

I wouldn't mind if it was a video I was currently watching but it's somehow remembering the last thing I started to watch. I can see no hint anywhere else that it's still active in any way at all.

The only way to get rid seems to be to close Firfox.

This is very annoying because it seems you can't watch anything without Firefox remembering it and putting on the lock screen until the end of the session, so it could be cluttering things up all day unless I close everything and (in my case, because of prvicy settings) delete cookies and log myself out of most sites.

I've tried multiple searches but all I've found here is a post about turning off media.hardwaremediakeys.enabled but I don't actually want to do that, I just want Firefox to forget videos when I've closed the tab or navigated away from them.

Elsewhere I found a suggestion to disable dom.media.mediasession.enabled but that setting isn't found.

Any help much appreciated.

Dear friends,

Firefox on Linux does not allow entries in forms that are called up in IFRAME. It works perfectly on Android.

Does anyone know why this is the case? Uwe

Firefox 127.0 (64-Bit)

Apologies if I'm repeating a previous request - couldn't tell if it was submitted.

I'm running Windows 10. While changing the startup screen somehow an image I thought was deleted appeared and now is frozen, apparently on top of a Firefox window. I've rebooted, restarted and followed the Windows help suggestions with no success. Right now I don't know whether this is a Firefox or Windows problem. I updated Firefox today to the newest version before this happened.

Any help will be appreciated. I can open new Firefox windows.

P.B.

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.
