Firefox 147.0.2 (64-bit) on my Lenovo Yoga 7 Windows 11 Home has been randomly malfunctioning when i use the hover over tabs with the mouse to show what is in the tab (small image) Sometimes it just fails for several hours, other times it works fine on its own later that same day.

I have tried to find this inside the browser several times with trying to find this browser-tabs-card-Preview-enabled inside about:config But it doesn't seem to exist in this version and apparently you can't add a new rule inside the browser to solve it.

Google AI solutions search is outdated or the wrong version. My computer and browser are up to date. How do i fix this ? I don't want to uninstall it, lose my logins and the bookmarks if i am unable to sync my files after trying to reinstall the browser only to find out it has failed.

Been using Firefox since 2014 and as my primary browser for personal research, etc. and Google's Chrome about half the time for company-related work. It's been my favorite browser. I'm using the current updated Firefox 147.0.3 (aarch64) and and Apple's O/S macOS Sequoia Version 15.7.3.

However, for at least 8 months or more now, Firefox has become completely unreliable for downloading files to save on my virtual drive in my MacBook Pro M3 Max because it often if not always freezes up in the process. I have to curse again (!) then Force Quit, reboot, and everything instantly comes back up on the monitor as if nothing happened, only of course I did not accomplish the task of downloading and saving the file I needed to handle.

I have discovered by talking to folks and by researching Firefox's support information library that I'm "not alone".  Not by far.  This problem IS a Firefox issue.  I've tried to follow Firefox's several different solutions to overcome whatever the root cause of the problem is, but without success.  The TIME required to really go through this problem-solving process is a killer.  And, yea, since I'm physically practically in OPEN AI's backyard, I have consulted CHAT GPT and it also confirmed this issue between Firefox and Apple's O'S macOS Sequoia Version 15.7.3 and practically gave me a Masters thesis about.  Who has time for this?  Why can't Firefox solve this problem to make this easy for us?

S0 now, before I update my O/S to macOS Tahoe 26.3, does anyone know if between Apple and Firefox this problem has been solved? For 10 years it was never a problem. What the heck happened? Firefox is no longer my primary browser, for I never know for sure whether or not I'll need to download and save to my Mac's virtual drive a file.

Thanks for any constructive comments anyone may make! And Happy Friday. ~ GPB

Please fix for me this error

I have been using Google Messages in Firefox for over a year, and have never had any problem until the most recent Firefox update from Linux Mint. Google Messages loads on the tab, and everything seems fine. But when I click on a conversation on the left, it crashes as it's loading the conversation.

All of my software is up to date, i.e., no new software updates are indicated in the system tray (?) on the panel. Firefox info: mint-001 - 1.0 147.0.2 (64-bit)

Hopefully this gets fixed soon, because checking my messages using my PC saves so much time.

Thank you

I am signed in on all my devices. Yet nothing has synced since October 2025. So none of the books marks from my laptop display on my desktop in bookmark folder. The folders don't even match what is on my laptop. How do I fix and how do I prevent in the future?

I am unable to log into RBS site on Firefox but I can on Chrome and Edge. What's the problem and how do I fix it? This has only happened in the last couple of days.

The title says it all. I use Firefox on my home computer with Windows 10, and my work laptop using Windows 11. At home, URLs do not autocomplete when typing them in--settings are all on for this to work properly, and it used to work properly, but it does not work at all. At work, URLs complete just fine.

Firefox is not allowing me to reach links to medical portal websites to set up accounts saying they can't reach the site and perhaps a firewall is blocking it. I have other accounts on this same portal... HELP please.

I have recently begun to have hard 'hangs' while attempting to view a video on a site I'm already connected to. I've tried to overcome these hangs, but they continue to happen even after firefox has been in use for a short time. I have to restart my computer, since the hang is locking up all control input.
