I am moving away from Windows -- at least temporarily. I have purchased a Linux desktop CPU and would like to bring my Firefox bookmarks and settings. Is that possible? And secondly, I did have FIREFOX set up on this Linux, but something changed today -- it turned to all black and white, no color whatsoever. How can I get back to the page I set up?

I am having problems with a page on my local network NAS server. In console this message appears on every page I access:

Failed to fetch moz-extension://84d877f6-188e-f449-9e14-68b144dea3de/inline/injected.js, Import failed 3 times. Final error: crypto.randomUUID is not a function

          inject-content-scripts.js:5:897

To check if it was my code I tried this simple html page (apparently the page has to be inspected so that the code appears):

Dumb Page

new to firefox, i just did a blunder. i want to keep firefox separate from chrome. i accidentally had it transfer all chrome history, bookmarks, etc. trying desperately to undo. any help w/b appreciated.

Your instructions for migrating passwords from Safari to Firefox are outdated, ex.: there is no "Preferences" option, and no "..." to export

My Safari version on Macbook Pro is: Version 18.5 (20621.2.5.11.8) And my Macbook Pro runs: Sequoia 15.5

I have no idea what passwords from . csv.files are or where to find them on my Asus LinuxMint laptop?

 The only password and username that i entered into my LinuxLaptop  are the only usernames and passwords

that I've entered into my new computer. I've also entered my google Chrome username and password to set up my Thunderbird email service. I never wanted to sync all my usernames and passwords in my Acer laptop computer because I felt that that made it too simple for a hacker to access all of my personal Information and access to accounts. Mozilla Firefox wants a password for csv files or tsv files or HTML files ? I don' know what any of these files are or where to go to to find them or the passwords for these files. I just want to successfully transfer all of my Favorates folders and files then all my Documents and picture files to my new computer. I'm a Photography artist, Graphic Designer,abstract painter, and creative writer. I can't move forward in my creative pursuits without completing these tasks. Thanks very much for your help and information. I'm soon to be 80 years old and not a very good keypuncher on a computer. I'm happy to leave Microsoft Windows and Google behind but Linux Mint is all new to me.

I want to migrate everything from windows to linux, i've already synchronised browsers on both systems, but settings on linux didn't get overrided.

How can i make browser on linux exactly the same as on windows (including settingd)?

Trying to install Firefox on Windows 11. I tried to import profiles from the Win10 machine but it didn't work - profile not found. I uninstalled and reinstalled again but same problem. I thought i had removedFF from the system but a search in this PC revealed 4 .browser files, 14 version files labelled from 134.0.2 to 119.0, a Dropbox messaging file? And a Firefox folder in Appdata Roaming.

Can I delete all of these and start again with a clean install? Why does the installer leave so much rubbish behind?

Help!

Good evening. This might be a tough one and not sure if it is even possible. I have had Firefox on my Dell Desktop for about 6 years. Over that time I have made many tweaks via about:config to get it working and looking as great as can be. I did just purchase a new HP desktop and downloaded and synced Firefox. I was also able to set up the new PC next to the old one to make sure each settings menu is exact. But the appearance is off on so many levels. I have no idea how many tweaks I have made over the years but have no idea exactly where to start. I did not know if there was any way on the older PC with those tweaks made to get a log of some sort of what I changed on that Firefox.

Even with the settings menu exact in both versions I cannot figure out what changes I had made. It's not many but enough. I know it is crazy but here is 2 screenshots. The one on the right, the smaller one in general is from the old PC and how I want it to look. I have tried tweaking zoom and text on the new PC and it has been a disaster, hence looking here.

Thanks in advance.

I can't Import bookmarks from chrome, the option is missing. Everything else worked, and the option is not "hidden", when I clicked to import bookmarks were not imported.

I have followed all of the on line instructions to move/copy Bookmarks from Firefox Nightly (current version as of 20February025) to regular Firefox browser. Both are running on same machine. Nightly install is also running Firefox ad blockers. Following all of the instructions on line I can find to accomplish, but cannot move book marks to Firefox. Have copied bookmarks from Firefox Nightly as HTML file to stand alone device but unable to get the bookmarks to import from stand alone device into Firefox. Assistance please.
