I've been using Firefox since Windows first came out and NEVER had this problem (or any other) until about a month ago. After an update, my bookmarks sidebar failed to work. I tried to update again, but got the message "Secure Connection Failed". After many tries, I was able to load a 32 bit ( V 1390.1) which was offered from Mozilla. This despite the fact that my PC is a 64 bit machine. This 32 bit version works poorly! I've repeatedly tried to load a 64 bit version, hoping that it would work as Firefox has in the past. I am still getting the the message "Secure Connection Failed", Error Code Mozilla_pkix_error_key_pinning_failure. What is going on??? I like Firefox and I'm reluctant to change browsers, but it may become necessary. Operating systwm: windows 10. Bob N

While I am able to log into my Google account in Chrome, I am unable to do so in Firefox after the latest update. Whenever I try, I am redirected to the attached support page, which asks me to delete cookies and cache contents. Deleting those does not help.

Please help!

My homepage uses 4 rows. How do I change the transparency around the images of each of the links in these rows? It's set at 75%. I'd like to experiment with changing it but I forgot how I viewed this 75% info.

I keep getting notifications, supposedly from Mozilla and/or Microsoft on lower right of my screen, telling me the system is infected. How do i determine if these messages are valid, or a scam ? Turned computer off and back on--messages keep popping up.

I cannot get past the secure connection failed! I have cleared cookies, cache, etc. I have turned off the firewall, and restarted my computer more times that I can count....

Suddenly yesterday privacy badger popup and disabled my youtube channels..I disabled privacy badger but of no use..I cannot enter youtube channel..wtf is going on..Firefox just decided to enter this badger and throw my off entering youtube?? Pls send us what to do to fix it or we must disable and delete firefox from being my browser alltogether??

bold text It is not possible to watch videos in 1080p since the moment I installed the latest update. I have to reduce to 720 or 480 to get smooth motion. Running Windows 10. How can I fix this?

Here is one occurrence that describes my problem ...

I read the newspapers online; the New York Times, Washington Post and San Francisco Chronicle among them. When the site loads the first few screens are no problems, all of the graphics/pictures show normally. The problem happens as I scroll down. When I scroll, the graphics/pictures don't show. I have to do a reload to get them displayed. And this happens over and over as I scroll down. Once I get to the bottom and have done a number of reloads everything is now displayed properly. If I go up to the top and work my way down again, all of the graphics and pictures display properly.

This does not happen with either of the other browsers that I occasionally use (Norton, DuckDuck). But I very much prefer Firefox and would like to fix this.

Any ideas? Thanks!

When using full-screen mode on macOS, moving the mouse to the top of the screen causes the title bar to appear. This frequently interferes with tab switching and leads to accidental clicks.

Is there any way to disable this automatic title bar reveal? Or, ideally, can it be made to behave like Safari, where only the window buttons slide down from the top-left without showing the entire title bar?

I am unable to receive emails into my Gmail inbox using a normal window. I can send mail but not receive it. I am using a laptop with windows 11. I can use gmail both in and out in a private window. I can use it in Chrome and Edge. It's only Firefox. I've been sending test messages from my Proton account to my gmail account I've disabled all the addons for mail.google.com I don't know anything about pop/imap but I think it must be Firefox settings I've cleared the cache I've tried to sync everything but that only sync between tablet phone and laptop I've asked google for help and gone through the lists including a config check I've closed Firefox and restarted I've restarted my laptop I thought I'd use Private windows and set it all up, signed in on my tabs, saved them to a folder and arranged to start in private using the tabs in that folder but then I had to sign in to everything again when it started. Signing in to Google is a pain in the arse as it is to sign in to X I've spent 6 hours so far...... I've used FF for years, the easy answer is to use Edge but I don't like it that much Please help.

I have no idea what just happened. I went to log off a website and a notification popped up that said "Check browser's developer console". I searched here for "developer console" and there were 0 results. I did log off after the 2nd try so it's no big deal but I'm just wondering what that notification meant. It sounds kind of serious. What did it mean? Thanks!

After using Firefox 138.0.4 64-bit (most recent version) for a few hours I get this kind of glitch on my taskbar preview in Windows 11. Please see the image. It especially happens when I unsleep the computer and leave Firefox running I think. I have already tried a refresh and reinstall. Now I'm trying to run firefox with no extensions/addons in safe mode. If that doesn't work I'm going to start thinking something is wrong with Windows 11. Was there something in about:config I shouldn't have touched involving multiple processes? (I think that resets with a reinstall/refresh anyway) Anyone know how to make this go back to normal? I can reboot to fix it or restart explorer.exe in task manager but it comes back like this in a few hours of useage.

I'm sure I don't have anything else open. If I hover mouse over the blank "windows" I don't get any kind of tooltip and nothing changes but an X does appear. I can click it and nothing happens. Right and left clicking these windows does nothing. When I close Firefox they still remain. I closed Firefox and Firefox isn't running in the task manager anywhere, yet the blank windows remain.

I'm running Firefox 139.0.1 on Mac Sonoma 14.7.1.

Since FF V138, I've had this extremely frustrating problem where, approximately once a day and while the application is still running, Firefox seems to either auto-revert to an older version' 'or otherwise mess up the installation files. I don't get any notice this is happening until I try to open a new tab and it brings up the "You must restart Firefox" notice. When I click Restart, it pops up with "You've launched an older version of Firefox, so you won't keep any of your bookmarks because that would be unstable" error.

The only way I've found to fix it is to redownload the most recent install files, which, after the fresh install, will allow me to keep using Firefox with my bookmarks for the next 5-6 hours, before the whole process starts again.

I theoretically have auto-updates off; my settings are set to the other option, "Check for updates but let you choose to install them". Doesn't seem to make a difference. It only does this on my Mac; the FF install on my Windows machine works fine.

I really want to keep using FF. It's my preferred personal browser. But this is really messing with me! I was hopeful that 139.1 would fix it but same issue, so far.

When I type into Firefox www.gmail.com the message returned is "Looks like there’s a problem with this site https://searx.space/mail/u/0/ sent back an error. Error code: 404 Not Found

When I try to access Google Maps the message returned is "Looks like there’s a problem with this site https://searx.space/maps/place/Taman Bay/@45.3126101,36.7266254,12z/data=!3m1!4b1!4m5!3m4!1s0x40ee93c055efa761:0x94911e600ea680f6!8m2!3d45.2873681!4d36.7542667?hl=en sent back an error. Error code: 404 Not Found

When I try to access Google Translate the screen returned shows a listing of 74 online SearXNG instances.

What is going on? Why is Firefox pointing to SearXNG sites rather than Google? Grateful for advice of a fix. [I have eset Internet Security installed.] Unable to attach a screen shot at the moment - nothing will save just now as I have an eset scan running.
