You Tube will not go full screen. I've tried reinstalling, clearing cache, refreshing page, pressing F11. Nothing works. It will go full screen in a private browser, but not in a normal one.

A few weeks ago, I checked my passwords and logins tab only to find there was nothing there anymore. Completely blank. I must have had at least 50 logins saved there. I'm not sure if there was an update around the time, but I believe I checked and saw there was. Has this happened to anyone else? Were you able to get them back? This is my wake up call to completely stop using the password manager feature of any browser ever. Totally disappointed

Firefox was crashing so I found the folder in C:Program Files and renamed it before a new install. I downloaded the new Installer and installed Firefox again thinking all would be saved, but now, my bookmarks are missing and the history from the last few weeks are gone and started with the date I re-installed it. I have an old AT&T email that is now Yahoo and been using it for years. I tried to log in and I get a different screen asking about an ID which I don't have. Firefox always launched showing this icon to start yahoo as well as Chase Ect...ect and all are gone.

Is there a way to point to the old folder, after changing it back to original name and get back to previous version?

I did find another Mozilla file under Users,ComputerName,AppData, Local. I don't know if it was created with the new install or there before and just updated because I renamed the first file I found and now it's using C:Users to start Firefox. Any help getting back to where I was is appreciated.

Thank you

Tony

Firefox history contains youtube videos I didn't watch (and that aren't in my google youtube history). I've realised they go back May, roughly when I got my new linux machine and installed Firefox. However, they also seem to have been watched outside the time any of my devices apart from my phone are on. They're mostly just junk videos about minecraft etc.

See attached pic - the ones this morning between 5.48 and 7am I didn't have the laptop turned on. My phone was on though, but by the bed.

How has this happened and how can I track down how to stop it?

I'm writing this on my Windows desktop, can send details of other devices if useful.

Hi, A few weeks ago, I wanted to sync my open Firefox tabs between my old laptop and my new one. I signed in to my Mozilla account on both computers, and the sync process worked just fine. For weeks, my synced tabs appeared in my Firefox sidebar on my new laptop, and all was good. However, the other day, I had to restart my computer a few times, and when I open Firefox again, my synced tabs were gone. On my Mozilla account page, it still says that I am signed in to my old laptop. How can I see my synced tabs again? Thank you very much for your help!

Is there a way to block pop-ups on Meredith Dotdash websites, e,g. seriouseats.com, foodandwine.com, etc. Please see attachments

hi and thanks --

all of a sudden, for no particular reason i can think of, my e-mail (gmail) has quit autofilling e-mail addresses when i type someone's name as a recipient. i haven't changed any settings. one day it worked, the next day it quit working.

help!

Hello! My download settings are (and have always been): always ask where to download files (in all options). In the latest versions, Firefox automatically opens downloads in a new tab without asking and downloads them to the default folder. This is an inconvenience for me. Thank you for your attention

It is really very strange and unbelievable! No page is open, but the memory occupies more than 700 MB and uses more than 20% cpu! What should I do exactly? I use Windows 11 24 H2

Starting from Firefox 132, HTTP sites cannot be loaded at all.

This is tested on a brand new installation of Firefox 132 without any profiles on Windows 11.

I can't upload videos to YouTube via Firefox. Uploading progress stays on 0%. Using the Edge browser videos upload normally. It has always worked with Firefox previously.

Firefox is a browser but not a search engine correct me if I'm wrong. Also now when typing in the search box down by the start button searches come up but I cannot get links to open when I click on them and even if I right click on them nothing happens

I'm having trouble with the current file Explorer being overlayed with a old file Explorer and a comment 'firefox symbol and word "file upload". This is happening while I'm trying to insert a document file into a online web page for a doctor. When I click the insert button on page that is when the Explorer is failing as noted above. Can someone help (send me a message on my e-mail *Email removed for privacy*@gmail.com if you can help/or update the help screen) Thanks Perry

I've been trying to locate the cause of this for the longest time and I can't. I have my Macbook hooked up to a Displaylink dock. Everything is running the most recent versions, the Mac, Firefox, etc. Randomly the windows will all show as they're not active and I'm not able to make any of them active. I can't click links, I can't exit out using the mouse, but hiting enter on the exit prompt will work. Have you seen this before? Do you know what is causing it or how to fix?

I have the same problems as several others. Bought a new computer and cant get download helper to pin to pin to the toolbar. Have tried hitting the puzzle piece and finding the tab after that for extensions but still cant find how to pin it as it does not give me that option.

I currently can't stream anything, and this keep getting this message: Widevine Content Decryption Module provided by Google Inc. will be installed shortly,but it never installs.

I have a macbook air and am currently running macOS Sequoia version 15.0.1.

I tried uninstalling and reinstalling, removing extensions, clearing cache and data, unchecking and then checking back again the reproduce drm protected content but nothing has worked.
