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

I use several devices with Firefox installed and I find that sync is not always "sync"-ing, or at least not very often. I can confirm I am logged-in the browsers. I do tend to leave my laptops in sleep mode and maybe sync is triggered only at browser closing? Whatever the case, I end up having bookmarks that I deleted from another machine still persisting on another for some reason or adding a bookmark on one laptop and not having it on another even hour later. Would you please take into account the option to sync at certain intervals like minutes, hours etc and let the user pick how often they want this?

Thanks! Constantin

I'm using Kubuntu 24.04. I saw it more than once. Firefox is frozen, no WiFi for example, and I have to kill it via terminal. After that it is not possible to retrieve the session (3 or 4 tab groups plus ~20 tabs)

thank you for any help.

While transferring data from the old profile manager system to the new one, I accidentally created one more profile than I needed. I have tried to delete the extra profile on multiple occasions, it won't go away. I have attempted to delete it through the profile management ui, and I went into the files and delete the associated data. On both occasions, the profile remained in the UI. I am unable to edit anything about the profile either. Is there anything I can do to resolve this annoyance?

if I had 30 bookmarks, there was no problem to sort all by name, if I´ve had 40 bookmarks I must sort it 3 times but then it works. But now I have more than 50 bookmarks and I testet it every update but it dosen´t work, why ?

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.)

How to get rid of auto saved bad email addresses? Someone used my friends NAME but a DIFFERENT EMAIL ADDRESS two or three times, and I accidentally pick the bad address & she doesn't get her email!!!! These addresses are Not in my address book, just in the aol drop down box.

When Firefox updated I only created a default profile and could not or did not import bookmarks. They seem lost now. I was offered to import from other browsers like Edge but did not see any way to import from my previous Firefox version. I am unable to find any automatic backups in bookmarkbackups folder.

Images appear fine, but lately I cannot see embedded videos on websites when I'm browsing. This is a recent change (past couple of weeks).

I can view the same videos using another browser, so I think this is a firefox setting possibly.

In recent activity if I click the kebab menu and select Delete from history the thumbnail disappears to reappear again after a couple of seconds. Only after repeatedly clicking Delete from history the activity actually disappears.

Is this normal behaviour?

”Using my HP Notebook computer, BOOKMARKS (in Mozilla/Firefox): Who governs my access to my list, which disappeared on 2/20/2026. It looks like Google (i.e., Yahoo) has taken control of this function……….and, if I set up Sync on my computer, how will my current DEFAULT YAHOO EMAIL be impacted?”

I manually clear all youtube cookies. I have these youtube exceptions. After going to youtube, then checking "Manage Cookies and Site Data" I still see Firefox saved a youtube cookie.

Thank you
