Firefox: форум сообщества

Hello. 😊 I have a question about my copy of Firefox for Windows v152.0.6 x64. (For the record, I have nasty feeling that I'm using the wrong forum; but the address bar says I'm in the right one.)

In my main profile, the one that I have been using for years, the "Home and Startup" part of my settings page shows the following:

- Firefox Home

 - Search
 - **Weather**
 - Shortcut
 - Support Firefox
 - Recent Activity
   - Visited pages
   - Bookmarks
   - Most recent download
   - [Choose a wallpaper]
 - Firefox logo

Today, I went to about:profiles and created a new profile. This new profile offers different settings:

- Firefox Home

 - Search
 - **Widgets**
   - **Lists**
   - **Timer**
   - **Sports**
   - **Clock**
   - **Weather**
 - Shortcuts
 - Support Firefox
 - Recent Activity
   - Visited pages
   - Bookmarks
   - Most recent download
   - [Choose a wallpaper]
 - Firefox logo

That's strange, isn't it? Why the difference? And how can get all the goodies of the new profile under my old profile?

Hello I just filled out a pdf and the font or writing came out blue I want it in black is there some where in Firefox i can get it in black w font or writing please Advise thank you

I have to reload history, bookmarks, passwords each 3 - 4 days, when Firefox refreshes the software. It was not happening before, just in the last two moths. How can I fix it?

I’m using the latest stable Firefox package from the official Mozilla repository for Ubuntu, on a system with 32GB of RAM.

I’m also using Microsoft Teams for work calls, in the browser (because Linux) and I notice that Ubuntu has killed the FF process twice last week because it was using too much memory - see attached image. I’ve only had 4 or 5 Teams calls last week so this isn’t a great success rate. It seems that after half an hour or so, FF has hogged so much memory that the OS feels the need to kill it.

If this is a known issue: are there any known workarounds?

If this is not a known issue :Can I help by providing troubleshooting data? How?

Thanks in advance!

Subject: Firefox Sync appears to have erased all bookmarks after setting up a new Windows installation

Hello Mozilla Support,

I believe I have encountered a Firefox Sync issue that resulted in the loss of my entire bookmarks collection.

Here is exactly what happened:

I have been using Firefox Sync for several years without any issues. This was not my first Windows reinstallation. I have restored Firefox through Sync multiple times before. Firefox Sync had always synchronized bookmarks, passwords, history, extensions and open tabs correctly across my Windows PC and Android phone. I had approximately 350 bookmarks, organized into folders. Timeline Yesterday I performed a clean installation of Windows 11. I installed Firefox 152.0.5 (64-bit). I signed into my existing Firefox Account. I did not immediately enable Sync, so nothing was synchronized at that point. Today I enabled Sync and waited for the synchronization to complete. Passwords synchronized successfully. Browsing history synchronized successfully (it took a little longer). Extensions were restored successfully. Bookmarks never appeared.

Immediately after noticing this, I checked Firefox on my Android phone.

At first, one of the bookmark folders still showed that it contained more than 300 items (I saw the item count), but when I opened the folder it was completely empty. After synchronization finished, all bookmarks disappeared from both devices.

Additional information Browsing history is still present. Saved passwords are still present. Extensions are still present. Open tabs synchronization continues to work. Bookmark synchronization is enabled. I am signed into the correct Firefox Account. The second local Firefox profile is empty. The automatic bookmark backup now contains only the current state (7 items), indicating that the original backup has already been overwritten. The current profile contains both places.sqlite and places.sqlite-wal. The only Sync error log is related to a temporary DNS lookup failure (NS_ERROR_UNKNOWN_HOST) and contains no bookmark synchronization errors.

Because history, passwords and extensions synchronized correctly, this does not appear to be an account or authentication problem.

What concerns me most is that I briefly saw the bookmark folder still reporting over 300 items on Android before it became empty. This makes me suspect that something went wrong during bookmark synchronization rather than the bookmarks simply never existing on the server.

Could you please advise:

Is there any server-side recovery or investigation that can be performed for Firefox Sync bookmark data? Are there any diagnostic logs that I can provide? Is this a known issue with Firefox Sync after connecting a newly installed device?

I would greatly appreciate any assistance, as this bookmark collection had been accumulated over many years.

I have a Sync error log available: error-sync-1783454370913.txt

It only contains a DNS error related to tabs synchronization: NS_ERROR_UNKNOWN_HOST

There are no bookmark-related errors in the log.

Thank you.

I'm using Firefox 153.0 on a Windows 11 desktop. I'm trying to use the feature that backs up my profile (bookmarks, history, and other data). When I turn Backup on, I'm asked where to store the backup, and I accept the default of putting it on my OneDrive. When a backup begins, an empty folder named "Restore Firefox" appears in my OneDrive, as expected. Firefox shows a message like "backup in progress." After a minute or so, the "Restore Firefox" folder disappears. After another minute or so (not immediately), Firefox tells me the backup failed and that I should try again later.

I assume the backup failed because the folder it was trying to use isn't there, but why did it get deleted?

There is ample space on my OneDrive and on my local system (100s of GB). I am using the ESET security software package, but it did not raise any warnings or errors.

Не працює розширення Firefox multi account containers, firefox не бачить моїх налаштованих проксі, контейнери відкриваються не під тими проксі які налаштовані в них

Hello Mozilla Community!

I've been at this for about two months and can simply not find a solution. I normally have 40+ tabs open in my desktop browser. I can put my mouse cursor/pointer over the tabs and using my scroll wheel shift visible tabs left or right (not actually switching to another tab).

All of the sudden it seemed that when I do this the tabs just absolutely fly by. Like I can't shift just two or three tabs at a time, it's shifting 10+ tabs with just a single scroll wheel 'click'.

I can see ten tabs or so and I know that what I want is just a few to the right, when i begin to scroll them the tab I want goes shooting by so far left it's gone now. I 'm left having to click the left/right arrows to move just one tab at a time, but if I click them too fast I get basically the same response. They just go flying by.

How can I slow this down without also changing the vertical scroll speed of the mouse when reading long webpages?

Thank you, John

I lost all bookmarks on or about June 29, 2026 after doing a Firefox update that asked me to create a profile when I'd never had one before. I have not been able to recover them.

Why is it so difficult for Facebook to function like it does in Chrome. I am a Firefox user on Windows 11. Facebook should function freely and without having to wait for actions to complete. I want Facebook to work normally on Firefox. It should not function like I'm driving a Mack Truck. Firefox, you need to fix this so Facebook functions normally.

Until a week or so ago this site ( https://sites.google.com/view/lve-construction/july-12-2026 ) displayed photos without a problem. It no longer does, just empty boxes. I have not changed any settings on Firefox. Both Edge & Chrome display without issues. See empty image.

I utilize a website called Twinspires for wagering on horses. It has a video popup (no sidebar tabs) that one can engage to watch the race outside of the Firefox browser. I quite like this feature. That said, I keep quite sidebar tabs saved as I use that feature to pin and then revisit websites that I want to spend more time on. Problem: If the browser closes on its own or other issue, it doesn't close the video popup. So when I restart the browser it "thinks" that video popup, with no saved sidebar tabs, was the last browser open so I lose all my saved sidebar tabs. If everything Firefox would close when the browser does, one could restore all tabs under history like one would normally do. Is there a setting so everything Firefox that is open closes when the browser does? Thank you.
