Updated recently from (I believe) 138.04 to 139.0.1, and immediately noticed that the size of font (and icons) had changed in the folders I have in the bookmark toolbar, that is they are much smaller and thus also less space between. Why this, and is it possible to change the size, without changing something else?

It's possible that many don't have folders in the toolbar and thus don't notice, but I have 2-3 apart from bookmarks.

I remember a change many versions ago that increased the space between entries in the bookmark menu, and also in the bookmark toolbar folders. That was too much and I found a setting [in config] that could be changed to decrease the space back then. (I haven't looked for that solution now, probably have some doc somewhere, and won't bother searching since this is different. Same with this case; I did some quick initial search but found next to nothing and older. BTW, this is one of the downsides of changes like these and similar; the day you have too move to another OS version, i.e. reinstall everything you also have to keep documentation of all these little changes, apart from all the other things you'll have to export or save.)

Google, gmail, you tube, etc SUDDENLY cannot load in Firefox on Mac but work fine in Safari on same Mac.

I get this message:Did Not Connect: Potential Security Issue

I have Firefox 139.0.1

This was working this morning but stopped in the afternoon. I use Duck Duck Go but I also tried switching to Google browser but got nowhere. Firefox loads everything else just fine. But no Google related sites.

I have deleted history, cache, cookies. Restarted the Mac. Closed and reopened Firefox. Again, all other sites accessed, just not anything related to Google.

I can see gmail on Firefox focus on my Ipad that is on the same internet connection as the Mac. This is really annoying.

For the better part of a year now I have to reinstall FireFox almost daily. It just stops opening tabs. I get a tab crashed error and the only way to get it to navigate to websites is to shut down FF and reopen it. Then at least half the time when I shut it down I get a new error that this is an old version of FF and I have to create a new profile. I'm not interested in creating a new profile. I've had this one for years and years. So then I have to use Chrome to download the FF installer again and reinstall to get it to work. I really prefer FF but it's almost unusable at this point. What is going on at Mozilla that their browser no longer works on Windows 10 or 11?

Firefox is not letting me access my Windows or Microsoft account. (using WIndows 11) The login popup is asking for School or Work email, which is not applicable to me. I input my usual login information and Microsoft pop-up says account does not exist. When I login to Windows, using a different desktop (Windows 10), I do not have login in issues.

What is the browser setting that needs to be updated.

Bonjour, ce matin 2 juin 2025 j'ai vu qu'il était possible de faire des recherches en changeant uniquement le moteur de recherche qui figure sur une liste. Mais je suis incapable de trouver la page de Mozilla Firefox qui s'est ouverte en premier AVEC MA CONNEXION INTERNET CE MATIN COMMENT PUIS6JE RETROUVER CETTE PAGE ? Cordialement Dominique

I accidentally blocked a web site that I need. I have followed all of the instructions to unblock (creating a master password, etc) but it does not work. I need to get this site unblocked as soon as possible.

Sequoia 15.5 Firefox 139.0.1

Firefox recently enforced an update. After this update, I can no longer open file browser for attachments if a website offers this option (example: this very form, Browse... button does nothing). I can also not Save to PDF any more. In both instances, a spinning wheel will appear and then nothing will occur.

Hi, I'd love some help with this issue please. I have just bought a new Surface laptop and enabled sync from my desktop. But many of the bookmarks and none of the bookmark folders came across. I uninstalled and reinstalled Firefox but with the same result. I have an old Surface laptop that the new one is replacing and the syncing has worked perfectly on that. Any help would be really appreciated. Cheers, Graham

I just had to close Firefox and reopen it and when I did I lost all my pinned tabs even though I had the checkbox in settings ticked to keep them, I managed to recover most of them by going through bookmarks and history but some I can't get back and I can't remember the websites to do it manually, this is more than just annoying, I have lost some very important websites.

altho i have ticked " open all tabs on startup " in settings, my tabs, open sites , do not now appear how to recover this function on startup `? use win 10 thanks ed.

It is kinda annoying as I use the address bar also for searching. I used to select google.nl and type over it. Now, this resolving interferes and I end up with a "funny joke?zx=(numbers)&no_sw_cr=(number)" in the search bar. I suspect it has something to do with Firefox as this started with the update to 139.0.1 Thanks for any help.

Firefox 139.0.1 on windows 11

Heya. As the title says, the sync between firefox on my phone (android) and on my pc only works one way.

I can only access PC tabs/history from my phone but not vise versa. It was working at some point but I don't remember exactly when it stopped.

Just clicking "syncronise" in the options on PC results in an endless loading icon for the sync.

I tried updating Firefox on both my PC and phone but they are both up to date.

I tried to re-sync my phone, got prompted to a QR code, but "sync and save data" is not actually an option on firefox for android unless it's nested somewhere odd.

This is not the end of the world I guess as my bookmarks still seem to be synced at least, but I'd like to know what's going on here and how to re-sync without being prompted to an unusable QR code.

Thank you.

I'm only seeing this on a (Windows 11) laptop that connects via a proxy server. The proxy settings are greyed-out (unmodifiable), set to use system proxy settings.

When there are changes to the network, Firefox closes without me doing anything. When I re-open it, there's no indication of a problem. Is there anywhere to view events that might have triggered the browser closing?

Aside from troubleshooting mode, which I'll try, is there anything else I should do/check?
