When importing logins and notes and URL from Chrome to Firefox, why the latter doesn't bring notes and read double URLs?

All of my notes are gone and if similar URLs are doubled.

Sharing one screenshot, since I cannot share another due to privacy (until a Mozilla dev team asks for it directly without sharing it on public platform).

I have many computers and occasionally I wish to change OS. Is it possible for me to save my toobar of links and then to insert them when I install a new Firefox or other browser?

I'm trying to import my passwords; what I've read says I will find Logins and Passwords in the menu represented by three bars at the top right of my foxfire sign in page. The problem is I have three dots, not three lines, and nowhere do I see Logins and Passwords, just Passwords, and there's no import data option there. Sorry if this is lame. I'm old and clueless in the world of tech. Also, thanks for any assist.

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):

I recently importing bookmarks from another browser accidentally. I'd like to try and restore the bookmarks along with the passwords that I previously had. How can I do this? I tried to do a restore, but only found options from three or four years ago. Is there a way that I can import the bookmarks from last November?

Hello Mozilla Support Team,

I have been using Firefox for a long time, and recently I upgraded my Windows system. Before the upgrade, I had set Firefox to open PDFs directly in a PDF Reader other than Firefox’s built-in PDF viewer, and it worked perfectly. However, after the upgrade, Firefox now shows the "Opening when completed" message and opens PDFs slowly, instead of opening them immediately in my chosen PDF Reader.

I have checked the settings, cleared the cache, refreshed Firefox, and even tested with other software, but the issue persists. The settings for handling PDFs are still the same, but they don't seem to work as they used to.

Can you please assist me in resolving this issue? Any help would be much appreciated.

Thank you

Hello, I'm currently using a Macbook Air, Early 2014, that still works perfectly fine for my needs. But it runs with OS X 10.9.5 and Firefox 78.15.0esr, that unfortunately can no longer be updated. That wouldn't be a problem to me since I do a very limited use of the computer, but now I'm getting the message "Your Firefox may start to have problems on January 14, 2025 since updates are not available for this OS". What should I do if I still want to use this device with Firefox to browse the internet? If it is impossible to keep using Firefox, any suggestions for an alternative browser that may still work? Safari is no longer an option. Thanks a lot for any and all replies

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.

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!

Kate (posting from an Android tablet, haven't tried to install FF on this yet)
