Tabs Unexpectedly Opening in New Windows in Full-Screen Mode on MacOS

Hi firefox community,

I am using Firefox version 127.0.2 as my main browser on MacOS Sonoma 14.5. For the past few months, when using Firefox in Mac's full-screen mode, I've been experiencing an issue where one of the multiple open tabs unexpectedly displays in a separate window the moment I click on it.

This behavior didn't occur previously, and I believe it started happening about 3 months ago. It doesn't happen every time, but occurs a few times a day when I least expect it, making it difficult to identify the specific conditions that trigger it. I use a Magic Trackpad, and after switching to full-screen using the three-finger gesture, the moment I try to activate a specific tab, that tab alone displays as a separate window in full-screen mode.

Is it possible that a Firefox version update has changed this behavior? If this is a Firefox issue, is there a way to capture debug logs to have the developers investigate it?

Alternatively, if there's an option to prevent tabs from opening in new separate windows, that would be an effective workaround. Could you please let me know if such an option exists?

Best regards,

Firefox periodically says I am "forbidden" to enter my Kaiser website (KP.org). I know what Mozilla recommends as a fix, which is to clear data and cookies. But this creates more problems because I have to re-enter passwords and other settings. This is a problem Mozilla's website reports has been occurring for YEARS! Why can't Mozilla/Firefox fix this? Please tell me there is a better way to fix this problem.

Version: Firefox 129 Ubuntu/Debian I'm using the Proton theme in Firefox and would like to revert the tabs to their previous, non-floating style. I've tried using the [profile]/chrome/userChrome.css method and enabling toolkit.legacyUserProfileCustomizations.stylesheets, but this hasn't worked. Is there another way to achieve this? Thanks for your help in advance!

Firefox ESR: Firefox translate not offered

Got a number of devices with Firefox installed, all of them Firefox Sync'ed. Most of them on rapid release version cycle and a couple of them on ESR.

When https://support.mozilla.org/en-US/kb/website-translation it provided a clean way to browse entire pages automatically translated. Problem is that the translate option is not there.

I'm at work right now on ESR 115.15.0 / Windows 10 64-bit and no translate icon appears on the address bar when checking German or French or Japanese sites (for example). Comparing my own browser settings to another, non-ESR FF it seems that on ESR something is missing. There is only a reference "Firefox Translations" and a "Exceptions" button to it. Check the attached image.

Can't tell if this is a bug or a feature (ie ESR lacks Firefox translate).

Today I installed a clean WIN10 version on my PC, expecting to just log into firefox afterwards and have all the data back within minutes, but I forgot my Firefox password... As I'm currently in another country I also couldn't just log in on any of my other devices to recover the password, so I decided to reset it via the E-Mail... well aparantly changing your password deletes the sync data?? I'm guessing there is no way to recover the data? So I got a relative of mine to start my backup notebook which has not been synched for a few months but some data should've still been there, at least I had thought so... password database there was empty... and instead of synching the firefox landing page from my notebook where all my pinned pages were, it copied the page from the new device and wiped that as well... Any way to revert the sync changes on the notebook?

I get the server not found error on almost anything.

Hmm. We’re having trouble finding that site. We can’t connect to the server at [literally almost any site] If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

The site usually loads after I wait like 2-3 mins before reloading the site, or I force reload it around 7 times, but I cannot find a way to make the issue go away. I have refreshed Firefox, I have uninstalled and reinstalled it fresh, I have opened Firefox in Troubleshooting mode and the issue persists. I am at the end of my wits. Someone please give me something else to try.

I've attached images of the problem I'm experiencing. Its like pixels are breaking/turning negative colors and it effects anything visible. I don't really understand what's causing this issue. It doesn't effect any other program on my computer/outside the firefox window, so I assume its a firefox issue. I've uninstalled/reinstalled the program with the refresh to hopefully fix the issue but it didn't work.

Google search no longer works on Firefox. Other browsers have no problems. Changing the default search engine on Firefox works (eg Bing), BUT. It can now find Google Maps, but Google Maps cannot find a location, because it uses a Google search. I tried the fix in about:config, but it had no effect.
