On my note 4 (Android 6.0.1) i'm using firefox 143.0.3 (Build #2016117407) and youtube stopped working (wheel turns then gives an error) . First i thought it's was the adblock so i disabled but that didn't fix it. So i used a proxy that also didn't worked. Then i used another browser (chrome, opera mini) and they worked. I didn't change any settings. I installed an addon User-Agent Switcher to change firefox desktop version which also didn't worked.

Edit: Opened only HTTPS mod in the options and did a full shutdown of the phone and now it works. I think youtube or someone else changed something and only HTTPS fixed that, not tech savvy enough to find why.

I just want to know WHERE the notifications land? I have a very old macbook pro (mid 2010) so I have a sneaking suspicion firefox is trying to tell me something about not being supported, yadayadayada, BUT where are the notifications? The OS am currently using is High Sierra 10.13.6 CAN ANYONE HELP ME OUT HERE? Sorry to be such a klutz but these banners appear every day and I can't seem to access whatever it is that firefox is trying to communicate. Thanks all!

I am used to having a Firefox for my personal Mozilla account, bookmarks and sessions, and Firefox Developer Edition to be logged in my work account, where I could use everything I need to work in a separate environment.

Recently I changed a job. Logged out past-job@mail.com from Firefox Developer Edition, logged in with present-job@mail.com and... I still can see old bookmarks.

- I cleared history and new bookmarks: nothing
- went to about:preferences#privacy and clear all the data: bookmarks still there
- tried Help > More troubleshooting information > Refresh Firefox…: all the same
- reinstalled firefox@developer-edition with brew: nah
- eventually, logged out from presetn-job@mail.com in Firefox Developer Edition and personal@mail.com in Firefox; uninstalled both, deleted everything related to "mozilla" and "firefox" was able to find in my system: unsuccessfully

The last thing I didn't try yet is burning my laptop in favor to a new one.

Where are those bookmarks? Why nothing is helping?

with a computer cleaning i deleted my passwords on my macbook. should not happen. on my iphone they still exist. how can i get all passwords from firefox on my phone back to my firefox browser on my macbook? when i sync i am afraid to delete the passwords on my phone too..

thanks for help sarah

Hello. I have a question. When I scan a PDF file in Firefox, it opens in a new window. Why? I don't mind it opening in a new tab, so I would prefer it to open in a tab.

So for some reason both the navigation and status bar always stay visible for me when I try to watching any full screen videos.

Does anyone know why this happens and if there is a solution to it?

Hi, I have my calendar connected to my Google calendar. It works great in both ways. I can add in Thunderbird and it show up in Google and vice versa. But one issue, when I get a meeting invitation and I accept, it always get in the "Home" calendar and not in my Google one. I have tried to sort them with my Google at top, and if I delete all other calendars it can not be saved at all. And can not find any other settings.

Any suggestions? Or is it just not possible? Maybe a function for a coming update? Or have I just missed out some obvious?

Best regards /Mike

I upgraded to 143.2 on iOS 26.0.1, but I cannot access any swipe tab gestures, which I assume means I can just swipe left and right in address bar to move between tabs.

I've seen on this forum from April that people are having an issue with Firefox and Google Passkey. I'm trying to log into my gmail accounts and can't get passkey to work. It freezes the browser and I'm not sure why this hasn't been resolved. Mac updated to Tahoe recently and I was on Sequoia 15.7.x (not sure exactly. Still froze. Photos are to show what's happening and that I needed to Force Quit each time.

Every time I update my drivers for Nvidia it of course reloads the screens. This causes all the tabs in Firefox to become separated on the Windows 11 taskbar. In other words, it looks like I have a new firefox window open for each tab (which I'm assuming is how it works but it's hidden most of the time).

It's not a HUGE deal per se, but it is kind of annoying. I have to close then reopen Firefox.

Like seeekerman who initiated the now-closed discussion at: https://support.mozilla.org/en-US/questions/1433369, I have used Firefox since its first release. With one exception - open image in new tab - I never use tabs. I want all the usable vertical space I can get.

For some time, Firefox on Windows (Windows 11, FF 143.0.4) has been showing a tab bar under the menu items, and above the bar with the URL etc.

How can I hide this when the FF window has only one tab, which is almost all the time for me?

The solution provided to seeekerman in that discussion, on 2023-12-08, was to create a userChrome.css file with some special incantations. I tried this it did not work.

When I try to send an email I get this message

"Sending of the message failed. An error occurred while sending mail. The mail server responded: Authentication required. Please verify that your email address is correct in your account settings and try again."

My email address in my account settings is correct. What can I do?

Hello, I wanted to create a script that doesn't allow me to disable a certain extension. For that I thought to locate the file in which the states of extensions are put. I searched online, and the answer appears to be that such file is available in extensions folder in my profile. However, I am unable to find extensions folder under my profile.

I would appreciate the help.

Hi, can the function mention above be remove or flag off somehow? For me watching icon is already enough. cause when hover the side of the website to navigate accidentally expand the sidebar and in some time is just expand many times probably due to a bug.

Issue Related to Backing Up Thunderbird Messages. Trying to back up both my inbox messages and sent messages. Problem relates to backing up inbox messages. First, attempted to back-up (sing the save as function) to desktop (folder). Plan was One Drive would back these up from Desktop. Have 199,000 messages in inbox. Did not save all of them. Then tried to save them in smaller increments to external storage (plenty of storage available). Successful with 4 back-ups of approximated 15,000 messages in each batch. Now will not back-up the full 15,000 ....last successful was 5,000 messages. When it fails, message says "Unable to save the message. Check your file name and try again later." The file naming convention has been the same for all files and have carefully checked to make sure it is not the file naming convention.

What is the problem? Does someone have a solution?

Can you please help me so I can successfully back-up all my inbox messages? Once I figure out an approach want to continue backing up messages using this approach.

Greatly appreciate your help!!

Best, Monica

Why do my new e-mails suddenly go immediately into my "Archive" folder and I have to transfer them to my InBox in the last few days? New e-mails have always gone into my InBox...until the last few days.

My father used my computer and synced all of his firefox “stuff”, i need to get rid of all of it.

I tried to log in, but came across a message that told me it would just merge with his stuff. I would like his bookmarks and passwords gone so that only mine occupy the browser.

Is there a reset?
