Default homepage is yahoo. Since the update to version 149, if I do a search from yahoo, the new tab that opens with the search result is blank most of the time. I have to click reload for the search results to show up.

Is anybody else having that problem? Seems to be yahoo search specific but not 100% sure.

How can I stop Firefox from automatic granting sites cross-site cookie permissions (see screenshot)? The problem is that the cross-site cookie(s) granted for a site more often than not is completely unrelated to that site. This problem is very frustrating.

I have tried changing several settings in Tracking Protection but nothing has stopped Firefox from auto-granting these permissions. I have for example turned off "Fix major site issues (recommended)" but it has not changed this behavior.

Thankful for any help.

I share my Sync account across 1 Android + 3 desktop devices (Win 10 or 11). So far no problems. A few days ago all the devices started dropping out of Sync.

I would say this all started with the Android device (v.153), which seems to have logged out of the account on its own. After reconnecting it, all the desktop devices went nuts...

1) desktop machines will need to reconnect to Mozilla account every time FF is launched 2) about:logins is always empty, even after logging back in and completing a sync routine 3) even when it states "Account disconnected" - "Sync is off", they will still receive tabs sent from the Android device; they can't send tabs as they won't see the other devices. Also, even while disconnected, they were able to add a new bookmark to the account. So, account is not actually fully disconnected... only some parts of Sync are.

Another symptom. Account's Connected Services list is clean and up to date (see images). Account recognizes new logins as already known hardware and avoids doubling them. But in Sync there's a mess of instances... all new attempts are seen as a new device. Many of these are of course dead links, as the latest login overwrites previous ones.

This happened while desktops were updating to v.154, but I wouldn't say it's related to that, as two of those machines also run a different Mozilla account on a second profile, and so far that account is not misbehaving.

The Android device also got disconnected a few more times, but now it seems more stable than its siblings, and the passwords are still accessible (as as you can see in the pics, it's not showing as a doubled Sync device).

I didn't try signing off all devices because I'm worried I won't be able to get back in... anyway, manually signing off a single one didn't change anything.

It seems to me this is a server-side issue. Is there a way to "refresh" the account without losing all data? Thank you

Hello,

I recently had an issue where I accidentally closed Firefox in such a manner that it did not save my Tab Groups... Should that be possible?

I am trying to recall the steps to cause this to happen. At the time I had two Firefox windows open: one with all of my usual tabs, and one with a single tab open. I believe the steps were as follows...

1. Closed Firefox window with all of my usual tabs open
2. Closed Firefox window with the one tab open
3. Opened Firefox, and the session with one tab open came up
4. Closed that session
5. Opened Firefox again, one tab open
6. Checked the 'List all Tabs' - Recent tab groups, Show All - This was blank

I assumed that Tab Groups would survive sessions being closed like that like how Bookmarks do, am I wrong in that?

The Address / Profile Autofill (full-form, 1-click filling) all of a sudden stopped working a few days ago. Only single-form works. I have to go to each box on a form individually and click on it to have the info fill in (Never had to do that before). And the "History" icon is showing to the left side of every info of mine that i click on to fill in (Never seen that before). Everything in the settings is still the same, nothing on my end has changed. It's set to automatically fill in my Name, Address, E-mail, Phone Number in 1-click, like it has THOUSANDS OF TIMES BEFORE. All my info is showing in settings, but not on any forms on any websites. The same websites i've been using all along, that filled in ALL my info with 1 click, all of a sudden went to single individual form last week. I asked AI what the problem could be. It gave me a few suggestions and fixes. Tried all of them, made no difference. All the settings it had me check were correct. HELP! (Thank you)

I recently got a new laptop. The FIREFOX app on my new laptop doesn't have File Edit View Bookmarks Profiles Tools and Help on the very top. I can't find my bookmarks with the folders I created.

Last Friday August 21 2026 my Firefox was updated from version 153.0.4 to version 154.0. Ever since then i can't use any of the Azure functions needed to see dead-letters in our service bus explorer. When i try the same in edge or chrome i get a prompt to allow access to local device network. Firefox doesn't show the prompt. In my settings no websites are listed in the Permissions and data list. When i look at the site specific permissions (shield button -> show site information -> permissions) it is set to default prompt. Clearing cookies or accessing through a private window makes no difference. I need to give Azure access to local network otherwise it throws a web socket error whenever i try to peek at any of our service bus messages. Anyone any ideas?

For some scrollables, v153 doesn't respect the Mac OS setting to hide scrollbars unless scrolling on page load. If that OS setting is adjusted after the page is loaded, then the page respects it again until refresh, so there's apparently some sort of race condition going on where it's not reading the setting in time before the page loads?

This is not a problem in v152. I downgraded back to v152 and it's working again.

After updating Firefox to the latest version (154.0) a short while ago, Firefox now insists on adding a “Firefox” icon to my Start Menu every time I open it. I do not need or want this additional icon, as I already have all the Firefox icons I want in exactly the place(s) where I want them. I am not finding a toggle for this behavior anywhere in the Settings menu structure, although I might be overlooking it. Is there a way to stop this annoying behavior besides rolling back to version 153?

(I am running Windows 11 on a desktop PC with all updates installed, and Firefox is set as my default browser.)

Why is about:home is completely blank? Updating to Firefox 153.03Beta made it all disappear. Must I reinstall Windows-XI for this user-interface not loading anything that has been updated on Firefox 155.03Beta? I will attempt an optimization and see if that does anything. If it does, I will close this; but if not, it is quite some new bug.

Right after updating Firefox to 155.03Beta, bookmarks, history, and synchronized tabs are completely empty on the sidebar. No data, at all, except for AI Chatbot's xml's. Didn't downloads once appear on the sidebar, too, by option? You have to go to Tabs and Browsing >> Browser Layout and select Show Sidebar to customize any of it. Library (Downloads and History) will not even show nor import anything. Not only this, but the new appearance of the sidebar is different, and about:preferences (settings) does not show their page titles, anymore, but only their icons. Settings tried to load when first opened, but it failed to name them. Is there some configured file and/or data on the beta that will not let each of these names and icons appear properly?

The password saver and autofill has worked for me for many years. However, recently (08/18/2026) on many login pages that I regularly use, it will not !! I did discover that, if I supply the first character of the USERNAME, only then Firefox will supply the rest.

I have Firefox 15.3.0.1 on two computers. One one, when I go to about:config, there is a search bar with an option to "Show only modified preferences." On the other computer this search bar is missing. How can I make it display on the second computer?

Hi,

Back in September 2025 we had the same issue for months and it was due to a Mozilla bug. This just happened today after the last Firefox update. I have a desktop with windows 10 and a pretty new laptop with windows 11 both from Dell. They both have the same problem.

I get the email from One Drive and I see the pictures on the email. I click on them to got One Drive to see them all and it goes gray, not loading pictures. I can see them in the Edge browser!!!!!

See the images from my previews post on Sept 2025 titled: "Unable to see "View all memories" on One Drive".

I really hope this does not take moths to be fixed again.
