The bookmarks and history system will not be functional" error message has been dogging me for several months. System is windows 11 home and Firefox version 151. All updates are current across windows and FF. I noticed on the about support page that FF shows that this is a NT Windows 10 OS, not Windows 11. Not sure what that means. I have followed all of the suggested fixes, multiple times. Some don't work at all and some work for a short period of time before the error message returns. The only fix that works the longest is to reinstall FF. This then requires the time consuming task of updating my settings, extensions, proxy, etc. When the next round of Windows security and / or FF updates come through the error message returns. Reluctantly getting ready to dump FF. This is my last ditch effort to find a solution. Thanks.

VPN has disconnected for NO REASON. This is a paid up year subscription. It has happened before. Just last month. I am running it on a windows 11 platform and use Firefox as my browser and Duck duck go as my search engine.

I have Windows 11 operating system on my Laptop, but when I order merchandise online via Paypal, I get notification stating my device was recognized and was using Windows 10! I don't understand why this is happening. How do I fix this?

only one email kinda working now - [email 1 removed]@wolfgangforge.com (have 3 accounts total). i cannot even be sure you are getting my emails or that i am receiving any replies. when i close down ff and re-start, the email tab is gone and i must type in "https://sm1.toast.net/interface/root#/email" and login to get it running again. my most important email, [email 2 removed]@wolfgangforge.com is not. this folder has my business tabs (using the Simple Tabs add-on in ms windows 11) - about 700 tabs and about 30 groups. losing all this info would be a major disaster! it is like FF is installing for the first time and cannot find the Profiles folder. i've attached a screenshot to show the folder where the Profiles are presently kept.

***-- i need to get back my ff as it was last friday.

i looked at the session-restore, but it appears that only goes back to the immediately previous session and since that one was fouled-up also, i can't see how that would help. wolfgang 503-475-3563

there's damn near always problems, pages display funny, dont load, the browser has its own " loading circle" temp files/cache is still a problem? do you guys know its 2025 and browsers still cant handle temp files? mozilla has ZERO help. no wonder everyone uses chrome. but they suck a$$ too.

Hello, I'm using Firefox 147.0.4 on Windows 11. When I open the Adobe Firefly website and I try to upload a file to the Adobe server using drag and drop or by browsing the Windows file system, nothing happens ... There's no error message, but the file isn't uploaded. Of course, this site works perfectly with Opera or Edge... On the Adobe forums, many users have the same problem with Firefox, and Adobe's response is always the same: change browsers ! Thank you for keeping me informed about the resolution of this problem, as I don't want to change browsers ! My email address is [edited email from community support forum]

Have a great day, Sincerely,

Mr. Fernandez

Today, "prioritized email" notifications started to show up in the lower right hand corner of the monitor. They are very annoying! How do I prevent from appearing on the screen?

So, after using firefox in the background to browse websites or watch videos I checked my memory usage in firefox with about:memory -> Measure and saw that youtube was consuming a decent amount >2GB (checked the main url when clicking the youtube src, it was the video on that sole tab i was watching and nothing else playing youtube in the bg) so i closed that tab, waited a bit and re-measured but then see that the memory usage for youtube rose about 200MB... and the website for youtube is that same url for the tab that i just closed (when checking the src in the results for Measure). I've been revisiting the about:memory page, reloaded it and re-Measured and youtube is STILL THERE. Even now, 10 minutes later i still see youtube there, with none of my tabs running youtube.

If i close firefox entirely and re-open my tabs then it'll very likely fix it but this has to be a major issue no? I shouldn't have to close the entire browser program just to fix a website visit, which is youtube of all websites.

As of this moment, firefox, with 8 tabs open, is consuming 4,452.99MB (~4.5GB) where 2.5GB is youtube for that page i closed.

I don't know if sharing memory reports from the about:memory page give my cookies away or leave me open to a similar vulnerability so I won't share it unless a dev or similar asks for it but for now, I've included an image showing all the tabs i have open on firefox, 2 windows.

I just installed Mozilla VPN but when it's active my internet connection stops working. Pretty sure whatever protocol it's using is the problem with the WIFI signal, but I can't find how to change the protocol like every other VPN service allows. How do I change the VPN protocol? There is strangely no article already on this site for this common problem.

MB is telling me to put MB on Firefox! BUT, I already have MB on Firefox. Can you help me.

Thank you,

Hi. According to my observations, only Mozilla Firefox and Adobe Reader have this problem so far.

Windows 11 + Multi-Monitoring Windows 10 have this Bug not !

Open Firefox, drag the window to the second or third monitor, and suddenly there is another hidden Firefox window on the taskbar of that display. If you move Firefox back to the main monitor, it disappears again. Or you can close Firefox and restart it on the desired monitor.

This is an annoying little bug, and I don't understand why Microsoft or Mozilla haven't fixed it yet. It's easy to reproduce and has obviously been around for a while. Since it only affects the two programs mentioned above so far, an MS update will probably not fix it; instead, the developers at Mozilla and Adobe need to address it.

Here the Same Topic in Adobe Forum. No bug fix to date

I hope you release a bug fix soon... but since that hasn't happened yet, I'm afraid it will take a while... I'm surprised, because I'm sure many people are experiencing this annoying problem, and in my opinion it's not a big challenge for your developers.

@Mozilla Please Fix this Bug. I know Windows 11 is not better than Windows 10 but Supports End and many Users and Customers used in Future this OS and if you don't want to lose any more market share, it's important to fix this minor bug for ordinary users too. Thanks ;-)
