Firefox has been my default browser for longer than I can remember. Over the years, I have maintained a significant bookmark file for work. I recently purchased a new computer, and my zero bookmarks from the new computer have replaced all of the bookmarks that I had in my old browser. This is a bookmark file that has successfully followed me through multiple computers and even my ios devices. And now it seems to be completely gone. I've looked at the places.sqlite files, and the largest one is 20MB and is in my current default profile, but it is dated today. That makes no sense because I do not have any bookmarks on this older computer, and my new computer doesn't have any either. The bookmarks have also been completely deleted from my iPad, but miraculously are still on my iPhone (evidently I had signed out of Firefox for iPhone at some point so they do exist somewhere.) The thought of trying to rebuild my bookmarks is nauseating. My only thought is to sign out of the browser on all devices, then sign back in and sync on the phone. Would that repopulate the main file with what's on my phone? Any other ideas?

I can't download anything anymore. I get the "failed" message. I see in support questons that this has been going on for a long time even though there have been repeated "fixes" reported. I've used Firefox for a long time and really prefer it, but I'm having to change to Chrome to be able to complete my work.

As soon as i start my computor with firefox i get this message: Warning you have virus. You must install re-captha-version-3-49.top. What is that? I have norton and norton says no virus. What shall i do?

fire fox usually has one row of frequently visited /fav web sites come up on the home page, but it has stopped doing this and even when i try and add them manually it wont accept them, the same when i try and boo marl a web page

Firefox has always maintained that current tabs will be restored after a reboot of the browser, and indeed that was the case for the first half-dozen years I've been a subscriber. That has not been the case for the past 4 - 6 months however. I have the correct Settings for this, so it is not on my end. Why do I always get a fresh Firefox browser whenever I update the version (which is quite regular lately . . . maybe a new version of Firefox every 3 weeks). Please help.

I'm a hiker and backpacker. I have recently begun using AllTrails.com to record my hikes making them easier to share with others as well as to save them for my own records. Everything works fine except uploading photos. This aspect of the app does not work at all in Firefox. It does work with MS Edge and Google neither of which I want to use.

I'm a cybersecurity professional and I'm researching about Same Origin Policy, Cross Origin Resource Sharing and how firefox deal with those things. I've find out that versions before 102.1.0esr, cross-origin script GET requests used to attach cookies (Image 1), but in newer versions, it's not happening (Image 2). I checked the release notes but didn't find nothing about this change.

I would like to learn more about what changed and how Firefox is dealing with cookies, SOP and CORS.

Thanks!

Hi Support,

I have always been struggling with the idea of syncing two devices, that is main and secondary devices, and that when logged out of the secondary device, user details such as passwords, booksmarks and other important things are left bare on that browser or secondary device.

It is my believe that, after completing whatever task that led users to sync both devices, the moment the user logs out on the secondary computer, or any of the computers, the passwords, bookmarks, history and other essential details should not display again on such computer or browser anymore but apparently thats not the case with Mozilla Firefox browser.

Kindly look into that and work on it....THE SECURITY AND SAFETY OF THE USER IS LEFT WIDE OPEN!!!

I just wanted to remove NAME from downloaded file list NOT the file from hard drive. How to restore file deleted from the DOWNLOADS page ?

• Would be NICE if deleted files were moved to Recycle Bin to be able to be restored.

they disappeared one day and have not returned. Finally uninstalled fir fox and nothing came back the new homepage and bookmark arrangement is inadequate. How do I get the old one back?

Hello,

I made a download 10 months ago, it failed OK.

But every other week that same old download keeps on restarting and failing.. its some kindof bug.

It then piles up with all failed downloads from the last year and they all try to load again and again automatically.

I tried to reinstall firefox and all but its a weird bug.

I have screenshots if needed.

Best regards

Alex

I was told I had to change my gmail account to whatever system you have now. I believe I have taken all the necessary steps, but would like to know how I access the emails I had on the old gmail account.

Hi,

I'm getting errors when trying to make online card payments with Firefox. Things like, Invalid card number, not being able to type number in box provided, (No Cursor). It works ok on some sites but not others. However, if I switch to the Edge browser all transactions work perfectly. This has been happening for some time (Windows 11). I'm thinking this could be a bug but not sure.
