Diễn đàn hỗ trợ Firefox

I searched Microsoft forum and opened the first link (https://answers.microsoft.com/en-us). On Firefox, Go back one page (back arrow) button was not working on this website.

Starting a few weeks ago, firefox would not load any accounts via https://login.microsoftonline.com/ one one of my Macs.

I was running the latest version 121.xx on MAC 12.7.2

Nothing would fix the site issue, so I tried re-installing and refreshing Firefox. Followed all the troubleshooting steps.

Now firefox is completely broken. Tried creating a new profile. Running in safe mode, etc.

It sometimes will load pages, but extremely slow. But generally is unusable.

Firefox works on my other macs just fine (Profile uses sync with those machines)

Safari and Chrome work perfectly fine. No malware. No ISP issues. No firewall.

Please advise a fix or I guess I will delete everything firefox related.

This happens now a lot, sometimes I can uninstall Firefox reinstall and it works. That worked this time but only for a few days. I am back once again to where I get this error on every place I visit. I have cleared my cache etc.. uninstalled reinstalled did a restore. It is only Firefox all other browsers work fine. No idea what to do anymore and am sad because I prefer Firefox. I only have standard windows 11 home security stuff installed so nothing special or fancy firewalls. Tried turning on default fire wall. Tried all the instructions on the more info page the error screen leads to.

This error occurs on most all websites or places I need to log into

Secure Connection Failed

An error occurred during a connection to mail.google.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

Anyone know why this is happening and a solution?

I just upgrade my firefox, but it did not import my history, cookies, bookmarks or passwords. I found a backup of the bookmarks (in a bookmarkbackups folder) but how do I restore the everything else?

Can anyone help me out and others on this matter? several months ago appears FB decided to screw everyone over by arbitrarily forcing auto refresh. If you're reading something long and or have to step away for a moment it is gone.

Some have posted for chrome they have an extension that stopped it. The only one on FF does not work. I tried it, does nothing at all. Time for FF to fix this issues allowing you to turn it on or off at my will.

Thanks Mike

Ccleaner gives message of "Firefox needs to be closed. i though it was Ccleaner that was the problem. it's not Ccleaner's problem... I get the same message when I run advanced system care... when I click 'close for me' it just skips it over and over. i then run it after starting PC and it still tells me FF is running. the 1st time it lasted for weeks(summer-ish of 2023) and seemed to fix itself. and it also wasn't fixed with 1 or 2 FF updates because i was waiting to see after updates that it would be fixed but wasn't. And I can't find Firefox running in Windows or advanced system care task manager. which means i cant close it manually. so I'm pretty sure it's a Firefox system problem... somehow FF is still running hidden in the background. i run malware fighter and anti virus to see if something is using it but comes up empty.

I reset my pc and don't remember password I have logins that I don't have saved anywhere else on this account so I don't wanna reset it normally I only was able to login with login through google and I can prove I actually own the account in anyway other then password cause i changed it a bit ago and just can't think of the whole thing

I encounter this error only on my.nintendo.com. However nobody else I know encounters this (even using Firefox) and I do not encounter it on Edge browser.

When I open the site it stays for a few seconds, then loads an error page. Then this error page reloads itself every few seconds. I tried to include some Inspect tool details. Before a 404 error there are 303 and 302 responses. I live near my friends who do not have this issue (same ISP too) so it's not a regional issue. In the screenshots the four (and two more further down) red GETs below are all "304 Not Modified" status'd

I'm not sure what type of info I can dump from the browser or how, to help diagnose this. I'm on Windows 11 (though I was having this isue on my dual-booted Linux install too), on version 121.0.1 (see screenshot of About Firefox for more?)

Thank you for your time reading my post, please help me report this with more details.

Hi,

WSJ opinion pages won't load fully on Firefox. The same webpage works on other browsers. This has been a recurring issue ever since I switched over to Firefox. It's the main reason why I still keep Google Chrome around.

I've tried updating to the newest version of Firefox and also iOS. Also, clearing my cache/cookies works sometimes but the problem keeps coming back.

After a session with many tabs open, I will close the browser. It doesn't matter if I open browser immediately or the next day, or after rebooting computer, the same tabs remain.

I imported my bookmarks, but they're not displaying in the bookmarks toolbar. I've tried hiding it and unhiding and restarting the program/my computer. The imported bookmarks can be seen when I go to "recent bookmarks" in the manage your bookmarks section. It also says that they're listed in the bookmarks menu, but they're not visible outside of the manage bookmarks settings window.

Good afternoon:

Yesterday the youtube website loaded fine. Today, if I type youtube.com in the address bar & hit enter it doesn't load.

I thought maybe a corrupt add-on so I removed all youtube related add-ons then rebooted the laptop.

No difference. YT wouldn't load.

It loads fine on edge.

Any ideas?

Regards, Soul

I have Firefox set to open on the default home page with 2 rows of shortcuts. After an update yesterday, all my shortcuts disappeared on my work computer. They are still there on my laptop however. I tried to sync, no go. I have tried to re-add the shortcuts manually and it won't save it. It is important that I fix this as I have several tabs open and signed it to different websites that I work with and this saved me a lot of time.

Help!

I've written about this before and never got a working answer. I have to use Chrome or internet explorer for some work because FireFox won't open the sites. This problem hasn't been fixed by I clearing cache and cookies as recommended back when I first asked a year or so ago.

Now the latest website I haven't been able to use is the Post office! USPS.com -- If I try to track a mail piece using my tracking number the site can't bring it up. The site tries for long time then tells me to try later. When I try with another browser such as Chrome, the result is there within a couple of seconds. It looks like I'm going to have to leave FireFox which I hate as I've used it so long - over ten years at least.

Hi,

After restarting my MacBook today, it seems like Firefox has been updated. When I signed in to my account, all of my passwords as well as my search history and personal customization have been deleted.

This is a very unfortunate situation. Please advise on how this can be restored.

Kind regards, Oskar
