Diễn đàn hỗ trợ Firefox

Tor browser 14.5.8 (based on Mozilla Firefox 128.14.0esr) LibreWolf 143.0.3-1 Each uses 100% of a CPU thread on Linux Debian 13 (Trixie) with KDE, while internet is not accessible for hours. I have tried to open new empty tab and close single website tab in Tor browser, but that did not decrease the load. Firefox 140.3.1esr also uses around 100% when i count up all its CPU threads load.

Can anyone reproduce this? Maybe the browser needs to run for some time so the issue is reproducible. If you have idea what to try (i will not use different Firefox version), let me know exact steps.

Dear Community,

the userChrome.css I used to use to disable the search bar expansion on focus no longer works (http://userchrome.wesleybranton.com/megabar). I disabled all urlbar.search options in about:config. But Firefox still gives me suggestions when I start typing about (as in about:config).

toolkit.legacyUserProfileCustomizations.stylesheets is set to true. The userChrome.css is inside the chrome folder inside the profile directory. I'm on 140.3.1esr (64-bit).

How do I disable this for good?

Thanks in advance!

Hi,

Every time I restart my Firefox browsers they will sign me out of my Mozilla account. I can see the email address associated with my account and 'Account disconnected'. I have to go through the process again every time I use it. I am using default privacy & security settings.

I am using :

140.3.1esr (64-bit) on Debian Trixie 143.0.4 (aarch64) on MacOS Tahoe 26.0.1 143.0.1 (64-bit) on OpenSuse Tumbleweed 20250929

Can you please help me resolve this?

I go on holiday for 2 week and now cannot find my book marks or history - why the hell were we not told these would disappear? Have you become a google clone? Do you want to be a Microsoft edge. I am really pissed!

Macbook Pro using Tahoe 26.0.1; desktop freezes when Firefox 140.3 is active. Desktop icons do not work. Firefox has to be shutdown for the desktop icons to work.

Apparently y-all aren't to smart to understand the your customers do change their telephone numbers and email address from time to time. It appear to be to smart to have instruction to alert you customers to the location of the forms to be used to change passwords, customer names and email address. ya think?????????????

Hi I have a firefox account which I use on 2 macs and a PC as well as an android phone. For the past few months non of my book marks, passwords etc are being synced across the system and I have now completely different book marks on different devises. I have synced each computer multiple times without effect. This used to work perfectly before I changed my password a few months back. It is now reaching a point that firefox is no longer usable for me?? Thanks for your help
