The subject says it all. The "tabs from other devices" are a) Shown as a long flat list of links, not in their individual tabs, which is disappointing b) right click does nothing - doesn't open them as advertised

Bonjour, A chaque fois que j'essaie d'imprimer un PDF sur Firefox, il me sort des pages complètement noires sur une brother DCP. J'ouvre les mêmes PDF sur Edge et pas de problème pour les imprimer. Le problème vient bien de Firefox qui envoie n'importe quoi via pourtant le même driver qu'Edge. J'ai vidé mon toner de noir avec votre bug.

Сегодня обновил Mozilla FireFox до версии 146.0 (64-разрядный). После обновления в панели "закладки" (cntrl+B) появился ненужный мне цвет выделения только что открытой мною вкладки (смотри скриншот). Как поменять данный цвет на менее контрастный ? У меня включена "темная тема", цвет выделения - ядовито-голубой. Хочу изменить его на другой более мягкий цвет. Как это я могу сделать?

Today I updated Mozilla Firefox to version 146.0 (64-bit). After the update, the highlight color of the tab I just opened appeared in the bookmarks bar (Cntrl+B) in an unwanted way (see screenshot). How can I change this color to a less contrasting one? I have the "dark theme" enabled, and the highlight color is a bright blue. I want to change it to a softer color. How can I do this?

I tried several things, but nothing helped so far. I did an offline-scan with Windows Defender, I opened FF in troubleshoot mode, cleared cache etc. I got the following crash-ID:

bp-7a77a8ad-7637-4fba-bd20-9e4730251209

Maybe someone here is able to help me. Thanks in advance.

my windows 10 PC was saving my bookmarks perfectly and storing in bookmarks after pressing the "save" star (star turns black) until dec 4 but its no longer putting them in the bookmarks menu anymore even though star turned black? then also after numerous attempts to no avail a "edit" pop up came up and after pressing that it did not even come up with the drop down "save" option just a big nothing. My email is: [edited email from community support forum]. Can you help with this. (P.S. The article "Cant add change or save bookmarks" did not help either.) TIA.

Crash submitted, ID = 320cc808-4505-4cba-6e0f-9f2c2955d007 Still happens in troubleshoot mode. Still happens with extensions disabled (Ublock origin, Proton Pass) Started happening since Dec. 5, 2025 System is current with all Debian?Ubuntu updates installed (daily refreshes) Linux Kernel 6.8 on Lenovo Yoga i7 (ca. 2022) with Intel i5 & Intel graphics

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

Hello. The browser will start fine and run for most of the day. I haven't made any known changes to the PC. At some point the browser will crash for all tabs and all windows. Any attempt to refresh goes to the screen as seen in the attached image. The "Restore This Tab" button does not work. I have to close all Firefox windows. Then the browser will work again.

I'm using an Alien computer. Windows 11. Everything is up to date. Firefox version 145.0.2 (64-bit)

Thank you.

I have a chromebook with linux enabled and installed firefox according to mozilla's instruction - via the sudo get-apt command. The cursor changes from the default to a very small adwaita. I've spent hours googling this issue and everyone I've come across had used some third party repo or was trying to shove in their own custom cursor theme. Literally all I want is my regular cursor back, and I have no clue why mozilla would have a specifically set cursor for their browser instead of just having it default to os. I don't really know what I'm doing here, but I cannot begin to state how tired I am of messing with this dead-end issue.

Is there an application to get rid of 'Old Firefox Data' folder? I tried to remove it once on another machine and i lost all internet connection (needed a full Windows restore) so very nervous about this.

I was unexpectedly signed out of my account. I used my encryption key to sign back in which i have done before. I have never experienced this problem before. This time when i logged back in all of my saved passwords were gone. Is there any hope of fixing this issue?

I click on the top right button and choose password button. And I can't see any password I saved before. I have no idea why this things happened. Right now I couldn't see the password that I saved, but I can use the password when the firefox tells me I have saved one. I still need to see the password because I saved some password that I use for other platform on firefox. The screenshot attached below. what should I do now?

Good Morning, Please how can I add or take out in firefox the icon shortcuts with most visited sites that I use, Also firefox is adding by itself shortcuts to my opening page and I don't want to have more than 6 or 7 or firefox suggestions. Thank you for your help
