Diễn đàn hỗ trợ Firefox

I've been having this problem for about 10 years. It was raised in this thread but never solved.

When I launch Firefox, several recent bookmarks that had been at the bottom of a folder have moved to the top of the folder.

Moderator note: This question has been edited to correct the formatting.

As long as my computer doesn't go to sleep Im fine. If it does, when i open firefox, i must refresh to be able to find my bookmarks and passwords. What am I doing wrong? Thanks in advance! Micha

Why do we constantly receive daily(sometimes twice daily) request to download updates for Firefox - it is extremely irritating - we are thinking of removing Firefox altogether !

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Google AI solutions search is outdated or the wrong version.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.

I have two e mails, but when i try to go to my secondary email [email 1 removed]@gmail.com i always get my primary one, [email 2 removed]@gmail.com. why?

I changed my password, i got an email that a new recovery key was created. i was offered to download it during the process, but some addon closed that window. how can i get my new recovery key? thank you.

Scroll bar issue on some websites When accessing certain websites, the scroll bar disappears (for me, it's on the right side of the screen), and it's no longer possible to view the page content, even using the keyboard's scroll keys.

DETAILS Only affects certain websites Firefox is up to date No blocking extensions are installed Access is possible with another browser Thank you for your feedback, Sincerely, F. Vernoux

barre de défilement pour certains sites Lors de l'accès à certains sites la barre de défilement disparaît (pour moi à droite sur l'écran) et il n'est plus possible de consulter le contenu de la page même avec l'utilisation des touches de défilement du clavier; PRECISIONS Concerne seulement certains sites Firefox version à jour Pas d'extensions bloquantes Accès possible avec un autre navigateur Merci de votre retour, Cordialement, F.

Since a while, I think it is since I created an extra testprofile with "firefox-esr -P", but I've set my main profile as default again

When opening a link in another program than firefox I get always: a popup "Close Firefox" "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

I do have both firefox and firefox esr, I usually use regular firefox the second came with the debian 13 repository.

I keep the esr to test display issues for reproducibility on my personal desktop, because I manage debian 13 kiosk-style desktops with firefox-esr.

(I noticed also that the regular firefox profiles can not be opened in firefox esr, so I use an extra profile for esr)

I have my browser.sessionstore.max_windows_undo in about:config set to 60 – it's been like this and working fine for several months.

It's set to this high number because I use an assistive technology which creates a fresh pop-up every time I deploy it, and Firefox treats it as a browser window closure when I close the pop-up. Consequently, I can easily rattle through well over 25 window closures in a day.

It's not necessarily that each window contains dozens of tabs and copious data, but nevertheless Firefox still treats it as a window 'within the meaning of the act'!

I just went to reopen one closed window from a couple days ago which did contain many tabs (partly why I closed it in the first place), only to find that the 'recently-closed windows' context menu is now only showing 20 windows (18 of which are the aforementioned pop-up assistive technology windows)

The really vital window that I want to reopen is not showing.

I've double checked in about: config and the browser.sessionstore.max_windows_undo is still set to 60 windows; nothing has been altered or reset.

I updated Firefox to 147.0.4 yesterday evening, but the problem existed before I updated Firefox, and is still in evidence since updating.

Two questions:

1) Why is the Recently Closed Windows context menu not showing the full number of windows it has been successfully doing with no problem now for months? I used to have to scroll down to access the full extent of the 60, but they were always there.

2) Why has it arbitrarily changed to 25 windows?

3) [I lied – Our chief weapons etc...] Is there a way that – given about:config still implies that the most recent 60 windows are retrievable – that I can access beyond the 25 windows limit that are currently showing as reopenable?

Thanks very much

(And yes, I already have things like OneTab and Tab Session Manager add-ons, but disabled those just before closing the important window, because I was trying to locate which add-on was draining the CPU. I assumed my 'recently-closed windows' buffer of 60 would suffice while I disabled the add-ons.)

Please return my Computer to using Firefox default as my browser as it was 2/01 /2026.Ive tried several times to do this w/o success . I was using windows 11 and have been trying to get rid of MS365 which I never used but have been charged for a solution , but have been blocked and refused cancellation after they asked me to change my email address and PW . Insanely confusing !

i am having pop-up messages that there are viruses on my computer causing security & privacy issues, your timely help required as my work using my computer is lingering on.

Aloha — An update to Firefox must have occurred, and I am unable to access my open tabs and bookmarks. I have had a Firefox account for 15 years at least and a lot of information was in my folders and bookmarks. Please let me know how the information can be recovered. I tried to follow several of the instructions provided and was not able to fix the issue. I have a recovery code/Mozilla key, but I am not sure where or how to use it.

I do all my work and personal stuff on Firefox so I need timely assistance to fix the problem.

Thank you, Mike
