Hi,

ist the famous and great Mozilla FireFox Developer team aware of the issue and is working on it?

I am happey to describe in more detail if required. thx

For the last few days Firefox keeps dropping off as the default browser and seems to be defaulting to the Avast Secure Browser thats installed instead.

I keep changing it back via both Firefoxs settings and via Windows default settings but within 10 minutes it falls off again.

How can I make sure Firefox stays as my default browser?

I recently got a new PC with WINDOWS 10 and loaded Thunderbird to pick up my email. However, now the mail client keeps making new profile folders, which I keep trying to delete. I am up to 6 now. THey are all in my deleted section of my Local Folders. How do I remove them for good. I thought all deleted items were supposed to disappear once you close the program, no? I never had to even deal with Profile Folders on my older PC. Thank oyu for your assistance.

I am trying to setup an Outlook account on Thunderbird and I get an error: "Unable to log in at server. Probably wrong configuration, username or password." I have an existing Outlook account which I am able to use on the Outlook app on Windows, the Android app and the web version on outlook.live.com I wish to have an e-mail client on my Linux Mint machine from which I can access my Outlook e-mails. To do so, I went to the 'Account Setup' page on Thunderbird and used these to set up my account: Your Full Name: <My Name> Email address: <email-id>@outlook.com Password: <My Microsoft password which I use to sign in to Outlook> Under Manual configuration: INCOMING SERVER Protocol: IMAP Hostname: outlook.office365.com Port: 993 Connection Security: SSL/TLS Authentication method: OAuth2 Username: <email-id>@outlook.com OUTGOING SERVER Hostname: smtp.office365.com Port: 587 Connection security: STARTTLS Authentication method: OAuth2 Username: <email-id>@outlook.com

I am sure that the password I am using is indeed the correct password. I still get an error as shown in the screenshot on the Account Setup tab. How do I resolve this issue? Thanks a lot!

I would like to create bookmark folders WITHIN a bookmark folder. Example: I search the American South, so I have a SOUTH bookmark. But within that bookmark, I would like to have a subfolder for each state. Please help!

Hello,

I'm not able to upload files to certain websites using Firefox on Android.

When selecting a file for the phone's file manager, the file upload simply not starting.

However, Firefox on iOS doesn't have that issue.

Firefox version used is the latest one and it is the one from Google Play.

Tried another browser and it works great.

I use Firefox with a VPN. I also use the Chameleon extension to alter my fingerprint. When I log into Messenger.com it asks if this is me and gives my actual, physical location. I've checked in settings under location and it doesn't show any sites requesting my location. I have it open in one of the tabs where it's showing my location. I have block all location requests checked. How can I get Firefox to not show my physical location?

Also on this page, it gives I'm using Firefox and the OS I'm using. Both are supposed to be changed for fingerprinting protection.

This looks like it could be a big security loophole. Any help is appreciated.

Every so often while browsing, for several FF versions, now, hover card functionality on some sites will simply stop working, even after a complete browser restart. Eventually the cards come back on their own.

Not a crucial issue, frankly, but an annoying one, and I'd like to know why it keeps happening and what can be done to stop it.

I have a full current installation of Firefox, after a struggle to get Bing off my system (Win11) I briefly got back to a personalized start page which had a large text "Firefox" heading and allowed me to add apps in small boxes and click to start an app. That page has disappeared and all I get is the ad referred to in the title. How can I replace the ad with the page I can load with app icons?

Right now i love my HDR content in most scenarios, except on a few sites where its just bad. Is it possible to be able to block it on certain sites where you dont want to apply it?

Hello,

Relevant system referenced below:

MacBook Pro 2021 Mac OS 14.5 Firefox 126.0.1 (64-bit) Carbon Copy Cloner 6.1.11 (7673)

I have a case of vanishing bookmarks. I quit Firefox last evening with command-Q as I’ve done a thousand times before. When I launched it this morning I was greeted with Firefox with an empty Bookmarks Toolbar and “Getting started” message. I opened a Manage Bookmarks window and everything there was empty too. I found, as well, that all of my saved UIDs and passwords were gone except for three, two of which I haven’t used in months. Weird.

Next I opened Firefox Help and found information about Troubleshooting Mode; I restarted in troubleshooting mode but nothing had changed. After restarting in normal mode, I tried Restoring Bookmarks; I chose Manage Bookmarks from the dropdown and then clicked the button in the Library window. Restore showed only one file and it was created today with only 14 items. Selecting Choose File… showed Desktop with Old Firefox Data highlighted. In that folder was only w34y3u9y…628 folder. From there I selected bookmarkbackups and the only file there was bookmarks-2024-06-06_11…lz4, a file created at 3:33 today. I found the key4.db file and it was created at 3:33 today.

I have Carbon Copy Cloner and use it for a weekly backup to a remote SSD drive. There are a year's-worth or so of weekly backups on that device. I tried trashing Firefox and reinstalling it from last week’s backup. While this worked, it didn’t solve the issue; it was still like a fresh copy of Firefox with no bookmarks.

I’m hopeful that I can restore the bulk of the lost bookmarks from CCC but I have no clue as to which files/folders to restore and I don’t want to guess. If you think this is possible, please tell me which files or folders to replace. Should I delete the files to be replaced from the current system and if so where are they located? I’m comfortable using Terminal for basic purposes but need explicit directions for entering commands and navigating to locations or files.

Thanks for your time,

David

I installed update last week on iPad (17.5.1). lost all tabs;-( Also, now won't create new tabs. I am also not installing the new OSX update -- cuz . .. Plz help! many tx!

For the last several weeks (can't give an exact date, but it's been more than just a couple weeks, less than a couple months), both my husband and I have had issues loading videos in FF. We both have the latest version of FF. I went thru "Fix common audio and video issues" and did all those things, as well as trying to load the videos in troubleshooting mode. Nothing has helped (tho now that i cleared all the cache, i'm gonna have to log back into all those websites :( ). Nothing else is problematic. Our internet connection is fine. In fact, my husband has resorted to using MS browser to watch videos--they load fine in that browser. I have no other idea what to do. Searching your database for "youtube videos load slow" only resulted in a couple hits with no resolution. Hopefully this isn't the third. thanks

It seems as the interface thinks the window containing Thunderbird is longer than it actually is. The bottom part of the interface is missing and there's no scroll bar. This is most apparent to me in the Address book, where part of the fields is invisible, as are the Cancel/Save buttons. When I start Thunderbird, that bottom part of the interface would appear for about a second and then disappear. Resizing the window doesn't help.

When I start Thunderbird in Troubleshooting mode, the interface works fine, but "Reset toolbars and controls" and "Disable all add-ons" doesn't fixt the issue.

It might have started when I connected a secondary monitor, positioned above the primary. I thought disconnecting that monitor fixed it, but I since reconnected it and the issue now won't go away except when in Troubleshoot Mode.

It started this morning (6/23/24) the page for a YouTube video will load but the video doesn't play. I have cleared the cookies and cache, shut the browser down, restarted the computer, turned off all the extensions, and have turned off hardware acceleration. Nothing has changed, I can watch other videos on Firefox and Youtube work as normal on other browsers. Last night (6/22/26) before shutting down may computer for the night I had an update for Firefox and shut the browser so it could update. The image is of what the video section is displaying.

In the Settings menu, there is no option for “Address” under PRIVACY to save autofill addresses. There is a “Payment” option which allows me to save credit cards to autofill, but not for addresses.

Firefox recently got so much slower than normal. Usually it will take 5-10sec to load a full page .Now it loads very slow that I don't know how much time it takes to fully load the page.please help me with this problem. Thankyou

Lately YouTube playing videos have been playing super fast or skipping straight to the end. I mean, they are horribly fast.

Things to know:

• I am posting here because I can't determine whether browsers may have settings unique to them that I need to change. This also happens in Chrome, but not Edge.
• I was recently forced to upgrade to Windows 11 - I can't say this issue happened exactly at that time, but fairly recently after the upgrade. I am running Windows 11 Pro.
• This does NOT happen when playing in a private browser window, either Firefox or Chrome.
• Having the Mozilla VPN on or off has no effect.
• I am sure the playback speed is set to normal. I have tried changing the playback speed to anything but normal and then back to normal and the current video runs correctly UNTIL I play the next video.
• This does not happen with Vimeo.
• It does not happen in FF for Android.

Any questions, thoughts, or advice would be appreciated.
