I'm running Firefox 122.0.1 on a Windows 10 desktop PC, with a profile which includes a userChrome.css file which makes several layout and cosmetic changes.

I also have a laptop (also Windows 10) which has an old Firefox 97.0.1 installation, and I'd like to make the same changes on this machine which I'm used to on the main computer. I copied my desktop profile to the laptop, to the same directory as its present profile, but when I rebooted Firefox the transferred profile wasn't recognised.

While doing the transfer I received error messages about some of the folders: Destination path too long. This despite the fact that the registry flag to accept extended paths is set to 1. I had to skip several folders in order to complete the transfer.

Could this be the reason why the new profile isn't being picked up? Or is it because the two Firefoxes are of different versions?

I'd be grateful for any thoughts. Many thanks.

I run a business website, and I've been noticing significant slow loading times specifically for Firefox users. While the site works fine on other browsers, it seems that Firefox users experience delays, especially when browsing product pages or navigating through categories. Given that fast load times are critical for providing a positive user experience, I'm looking for specific recommendations to optimize my wholesale clothing website for Firefox. Could you provide any tips or best practices for improving page speed in Firefox, such as optimizing images, handling large product catalogs, improving script performance, or utilizing browser caching? I’m also open to any tools or Firefox-specific settings that might help speed up the site’s performance for my customers.

My Firefox instance (133.0.3 64bit) on notebook shows warnings for leaked passwords in my password manager. I can even search for unsafe passwords.

My Firefox instance (same version) on tower PC synchronizes the passwords, but doesn't show warnings (incl. the black key icon), though I checked the box in settings to do so, and restarted over and over. What else can I do?

I use Google and Firefox with newly installed Windows 11. Minimising a website I get the little Firefox icon in the bottom taskbar, but on opening a new website this closes and replaces the original one. I need to have several icons for different open sites which I can click on and move between as necessary. I can't work out how to do this.

When I scroll down the page on MSN and try to open a link in a new tab the page jumps back to the top. It then opens a link of another article that I never right/left click on. I have my mouse set up to left click to open a new tab. Does not occur on any other sites.

It has been doing this for months now.
