After a Windows 11 update, Firefox does not automatically start although set to do it and when I start it, a small rectangular box appears in the upper left corner of the screen.

Please resolve.

I use the Firefox browser.

While online, as I pressed a letter , Firefox closed, and its icon on the Taskbar disappeared.

After finding a Mozilla support page, and updating the browser, I found that all of my Bookmarks had disappeared.

And even worse. I tapped the 3 bars in the upper right corner to go to > Settings > Privacy Security > Saved Passwords. All of my Passwords were eliminated too. This is disastorous.

Help, I'm 71 years old.

I just opened my Thunderbird e-mail account, did thunderbid only access emails from my sbcglobal account email account or did TB download the the 100,000+ SBCglobal emails to a thunderbird file that I can continure to access?. I believe that AT&T is going to delete my sbcglobal email account as I have canceled my AT&T internet service. I see sbcglobal messages in thunderbird that go back to 2008 that I would like to read again. Will these messages disapper when AT&T disables the SBCglobal email account.

I've been wanting to access Thunderbird's encryption ability on both my laptop and desktop. However, in setting up Tbird on my laptop I notice the user Profile should stay on one computer. Can I use the same Profile on more than one computer using the same source and password? Can I open a new profile on a second computer, even though I would have to use the same email source, a local provider? If not, is there an online source of email data I can use on Tbird on my laptop. Thanks much, Bruce Bartrug

I am using Firefox on my MacOS Tahoe. There is a persistent annoying issue where whenever I close (physically fold) my laptop screen and reopen it, Firefox will be frozen. It will be frozen in the sense that I am unable to interact with any tabs or anything until I manually quit Firefox and reopen it (which automatically reopens all my tabs), making it usable again. This doesn't happen every time I close and reopen my Mac, but it definitely happens the majority of the time and makes the browser hard to use.

I've attached a screenshot of what a new window looks like when Firefox is frozen. It looks just like a Firefox window when unfocused.

Notes:

• It doesn't entirely freeze Firefox. In fact, I can "switch" to a different tab by clicking on the tab and then shutting and reopening my laptop again. The new tab will show on reopening but Firefox will still be frozen. This process can be repeated.
• I can pretty consistently replicate the bug by shutting my laptop, waiting 10 seconds, and reopening it. This will almost always result in the freeze.
• The bug still happens if I'm not focused on the Firefox window but on a different app.
• The bug doesn't seem to happen if I just lock my screen but don't shut it closed.

Things I've tried that haven't fixed it:

• Updating my OS.
• Restarting my laptop.
• Disabling hardware acceleration.
• Disabling themes and extensions.
• Deleting and reinstalling Firefox, including deleting the user data in the "Library/Application Support" folder.

Let me know if there's any more information I can provide or fixes I can try. Also let me know if I should go ahead and file a Firefox bug report for this. Thank you.

I am trying to organise my Firefox bookmarks into folders on my Mac Studio. However, when I try to use the highly-touted "just drag and drop advice" it does not work. It doesn't work in the drop down and it doesn't work in the bookmarks manager. Drag and drop functionality works elsewhere on my Mac just fine.

Note, if I open every single bookmark, click on the blue star, then re-assign the folder it does work. However, that it a mighty pain in the arse.

Since I know it will be asked...'yes' both Firefox and my MacOS are up-to-date. And 'no' I haven't upgraded to Tahoe.

I would appreciate any help that anyone can offer. Thanks!

Running Thunderbird 140.5.0esr

This has been happening for a few weeks now somewhat randomly. The folders under Mail for one of my accounts keep moving around and are not in alphabetical order anymore. Most folders are OK, but a few either jump to the top of bottom of the list. I can manually drag them back, only for different folders to do it the next time.

The folders in questions are 2 levels down from Mail.

The folders in my "LOCAL FOLDER" file usually have been in alphabetical order. As I have added new folders to store emails, the new folders have not been put in alphabetical order in the "LOCAL FOLDER" folder. They have been added to the end of the original list after the "Z" items. How do I re-alphabetize the whole "LOCAL FOLDER?"

I keep getting this message when I try to sign in on Firefox. Chrome let's me sign on but i much prefer Firefox. Any suggestion? {

I just bought an HP Omnidesk M02-0085m PC running Windows 11 Home edition. For some reason Prime video works in other browsers, but in Firefox I get audio and a black screen. I am not using any ad blockers and I have tried toggling performance settings on/off. Any suggestions?

Unlike before, many sites that I visit regularly, I am now having to log in every time I visit, including support.mozilla.org.

Did I unknowingly change something, some setting? or perhaps it's due to an addon?

I had chess scores and high level thinfags i had done I wanna be able to save them even if there locked i don't give my email to just anyone because its always full but I keep scoring high close on chess and your browser keeps deleting it. Now I could do it on a normal tabe but its capped and if you cant do it I know Google has the ability I just tested it out yesterday and they have a save incognito tabs with pin options so if tou guys cant help me and give me my lost game scores and elo im deleting the app permanently today and just switching to Google, Thanks for reading Ps this happened yesterday and there was a screen lock and I chose yours because I thought it still might be easier but the screen lock went away and now I lost all of the hard work I put in thats very frustrating

I'm running 145.0.2 on Mint Linux and Windows 11...

Like many other users, I have an issue in which roughly half of the icons representing bookmarks on my Bookmarks Toolbar have been replaced by the black+and+white icon of a globe. The links work, but because most of them are now the same, it means I have to hover over them to make sure I click on the link I want.

I've tried: Exporting all my bookmarks to HTML; deleting all bookmarks; re-importing Deleting the "favicons.sqlite" database and letting Firefox recreate it Creating a new Profile and importing all my bookmarks "fresh" in to there

Not only does none of this seem to work, the results are actually inconsistent.

This problem has been kicking around for years - certainly for many major releases of the browser. I understand that there could be deep/complicated issues such as a corrupt user profile, for example...

Unfortunately, however, there does not appear to be any consistent or reliable effective advice on how to fix this issue... and nothing I try seems to resolve the problem.

I'd be very grateful for any recommendations on a reliable repair for this issue.

But I'd also be grateful for suggestions as to how we might go about suggesting to the devs that this long-running bug is overdue a permanent fix.

Thanks in hope.

I'm so frustrated! I don't have time for this... I try to use my pw, it gets rejected. I hit "Forgot pw". I get confirmation code. I use confirmation code. I use computer-generated pw and Moz saves it. I try to log in again and pw gets rejected.

I am trying to get to my account to find out why the VPN I've been paying for for years is not active.

Hi everyone,

I've got a real curious problem. I'm a student at Berkeley City College. Firefox is my preferred browser. Sometime this semester, I stopped being able to access Google.com or any google subdomain sites like Google Calendar while using Firefox Desktop at school. Here's where it gets really weird. This only happens when I using firefox windows desktop while also being on the school network. If I switch to my phone tether network then I can access Google just fine. If I launch a different browser (that is not Firefox based) like Chrome, it works just fine. I tried accessing google using Waterfox on the campus network and encountered the same problem. I consider myself to be somewhat technically proficient but this is confounding me. How could the sites at a specific domain be blocked only while using a specific browser on a specific network???
