Firefox Community Forum

Just recently when logged onto Hotcopper.com.au have been getting a message that reads "This page is slowing Firefox down. To speed up this browser, stop this page." There is a STOP button, that helps for a moment or two only. When I open the program with MS Edge, the problem does nor occur. I was going to remove the Firefox App but saw the repair option. Repairing did not stop the problem. Any suggestions? John I have a near new Acer laptop running Win 11.

I've been using what I gather is an "older" profiles system via about:profiles.

Now if I:

1. go to about:profiles and open my second profile in another window, 2. close second window and about:profiles page, 3. open about:profiles again in first window,

I get "Another copy of Firefox has made changes to profiles. You must restart Firefox before making more changes."

This happens every single time, even though I've made zero changes to profiles, and is extremely annoying.

Can/should I migrate my profiles to the new profile manager? How to do this?

Would appreciate your help in advising how I can re-instate my Protonmail login as it just doesn't seem to want to let me access the site at all - it just tries to access and then keeps coming up with 'oops something went wrong'. It's like there is a block on letting me access? This has only just happened since doing firefox updates.

Cheers

Recently, Firefox has been slow and crashes regularly. I try to sync tabs but after it crashes and I reopen it goes back to a much older save and lose tabs I've recently opened or sometime after a crash and reopen it tries to open a window with no tabs and I lose all my tabs

15/12/2025 I need to sync my firefox data from my old windows 10 laptop to my new windows 11 laptop. Do I have to download the firefox app on to my new laptop before I can sync it, and will I need a new password if I have to download the app. Im using my old password on my old laptop to write this. On the new laptop, I tried to sign into firefox on the internet but, it said my password is wrong. I'm an oldie and have no idear what to do. Iwill be very grateful for any help. Many Thanks,

                                                                                           Janet.

Mir würde es sehr viel besser gefallen, wenn ein neues Lesezeichen immer automatisch oben im erwählten Lesezeichenordner einsortiert wird. Ist das irgendwo einstellbar?

When I try and connect to a site with firefox I get a message saying "Check that Firefox hass permission to access the web (you might be connected but behind a firewall) How can I get check to see if I am behind the firewall and if so how can I get out to connect to that specific site.

I just moved to a new computer. Still using the latest version of Firefox (145.x). But of course I have a much higher rez screen. So I'm looking at many more bookmarks across the menu bar, and they are all very small. As are the tabs at the top of the window. I can not find a way to make these larger in Settings. Grok tells me to work with CSS in the profiles folder, but that doesn't seem to work. (And I bet that every time a new version came out, I'd have to move or remake that CSS file and/or folder.) Is this just the way it is on the high-rez screen, or can someone point me to a solution?
