Diễn đàn hỗ trợ Firefox

Hi everyone.

Basically when the browser is (I think) idle while watching YouTube, FF is constantly backing up (the timestamp in the backup file name keeps getting updated). From the settings page I thought it once every 24 hours. I noticed from higher than normal CPU usage impacting FF and the Windows search indexer. Which reverted to normal once I disabled the backup.

I checked the about config:

• browser.backup.scheduled.minimum-time-between-backups-seconds

Is set to 24 hours (86400 seconds)

But I also noticed:

• browser.backup.scheduled.idle-threshold-seconds

Is set to 15 seconds(!). Is that what I think it is? Back up whenever there's a 15 sec idle window, regardless of the minimum? Can I safely make that 86400 seconds too, or does it do something else entirely?

Many thanks in advance.

All of a sudden my bookmarks and history have disappeared and I cannot add new bookmarks. I have researched this and tried everything I could find to fix - namely restarting FF, restarting the PC, renaming places.sqlite, using task manger to locate which app is locking the file. I also used the Places Database to Verify Integrity and here are the results: Task: checkIntegrity - Unable to fix corruption, places.sqlite will be replaced on next startup > Task: checkCoherence - The task queue was cleared by an error in another task. > Task: expire - The task queue was cleared by an error in another task. > Task: vacuum - The task queue was cleared by an error in another task. > Task: stats - The task queue was cleared by an error in another task. > Task: _refreshUI - The task queue was cleared by an error in another task.

Nothing has worked. Help!

Hello,

I can't save and download a modified PDF file.

To put it simple: I open a PDF file on Firefox; Rotate it clockwise; Open the Tools menu (»); Click Save; The saving window opens; I save the file; When I open it, the file is as at start, before rotating.

Windows 11 25H2 26200.7623, Firefox 147.0 Thank you for helping.

This is a brand new problem, for me. It just started today when using FireFox. On nearly all websites, including Mozilla support, when I click on an embedded link on a site, firefox asks me to select an app to open the https. Even if I tell it to let firefox open all https, it still asks me everytime. to make it better, it still doesn't always let me open the link and I go through the same thing when I click the link again.

This also happens when clicking on the search box in *any* search engine, e.g. Google, Startpage

See the image below.

I've attempted to change all cookie & tracking settings, no help. I even uninstalled and reinstalled Firefox.

This is making FireFox useless.

I had to use my default browser, Brave, just to submit this question. I only use FireFox for social media accounts, sites I need to link to my sm accounts and the occasional web search. For example, linking my Etsy shop to facebook. When I clicked the link "link to facebook" is when I noticed this problem.

I am running W11 (HOME). FF is acting like I am running W10 (I keep getting info on needing to upgrade to W11).

Now to the real problem:

It appears since I upgraded FF to 146.0.1 64 bit, FF seems to have problems pulling up password/ids that haven't been used for a while. It actually can't find them as if they had never been used. The number of "passwords" it lists is rather small (like 8). This is causing me to have to go through lost password routines.

Any idea what or why this is happening?

firefox suddenly stopped showing any history or book marks. also no history. i've re downloaded, no change. all works well with chrome but i like firefox. and thoughts?

Suddenly, i am finding when i get to the end of my bookmarks and scroll up, the bottom most bookmarks show up. And scrolling down, as i reach the last bookmarks, the topmost bookmarks show up.

Ever since the last update, I haven't been able to log into my yahoo account. I am able to access the account through other browsers and on my phone but not on my laptop.

Loading website for BacaPoa.frontsteps.com does not work, now fails ("not secured") . This is business site I have for years.? [windows 11] Is the a bypass or override I can do? JR

Whenever I try to access the Powerball website I get the following response -

The request is blocked. 20260116T144515Z-17584c64c9f58vrnhC1MIAm1t80000000t4g00000000rcec

I have no issue with other browsers.

Thanks Gary

1/19/26 I have used Firefox for years and now it looks like Microsoft Bing has taken over and I cannot get Firefox back. It installs to a certain point and stops. Can you help me? email: [edited email from community support forum]
