Firefox Community Forum

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 haven't used Firefox for a while but when i tried to import my bookmarks from Brave, they were imported but i cannot access them. i would have believed that Firefox would have either given me a 2nd listing or merged them into the ones i already have. am i to believe that this cannot be done? or am i overthinking this import thing?

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?

Bought a new Windows 11 computer. What sort of problems may I have transferring my data from Windows 7 Vista to windows 11. Any suggestions or instruction will be greatly appreciated. Thanks so much for your help..

I'm trying to import my bookmarks from an HTML file. They say to click the menu button but there is NO menu button with 3 horizontal stripes. I'm using a Chromebook laptop.

I've tried to import all the passwords I had saved on Brave, which I am leaving. There's one way which is in Firefox itself, where the little icons spin and it says passwords and other things have been saved. But the passwords have not come over. I've gone to several AI engines, and they have me create HTML or .csv files, but these aren't working either. When I tell AI this, I get suggestions so complicated I'd have to be an expert to use.
