My Firefox account and associated passwords were left open on another notebook. I have now changed my Firefox sync login password from a different PC and signed out of other devices. Can a user on the previous PC sign in with a password that is saved in Firefox?

Hello,

Before the release of Firefox 99, the drag and drop function of e-mail using OWA (Microsoft Outlook) stopped working. In the last version of 99, it started working again (and I was very happy). My browser just updated to 100 and it stopped working again (and, of course, Firefox recommends not downgrading).

This is getting very frustrating, as I use Firefox at work and it is actually a lot of time wasted, going in and attaching files without drag and drop. I am on the verge of abandoning Firefox as my browser, since these features work in both Safari and Chrome. However, I do like the usability and security of Firefox, so I am hoping you can fix this very soon.

Ver 100.0 Settings:Startup:Open previous windows and tabs is UNCHECKED. But every time I open Firefox, it opens the last site I had open before I closed it.

This worked before ver 100 and suddenly has stopped working with ver 100.

I even rebooted the computer (Win 10, 64-bit) and same behavior continues.

I can't say well what is it ...but when i open links from discord (twitch/yt/etc) the Firefox take too long to start load the page but if i just click on any link direct from firefox browser ..the page load faster

-windows 10 pro x64 22H2 -Firefox Dev 115.0b5 (i use dev to load unsigned pluggins) but the problem persist in all versions

Firefox crashes (tested in troubleshoot mode) for this URL : Link which causes crash https://developers.google.com/android/guides/opensource#java

There are no crash logs generated either (checked in about:crashes) . Attaching a post-crash dialog screenshot

The website I'm using most is 9gag.com

I can get the website to load again by choosing exit in Firefox to clear out all my data, then re-opening Firefox and logging in from scratch.

It will just hang on load screen, usually what you see before data begins to load.

I can reproduce it by removing Firefox from recents, then launching it again and re-opening the existing tab, or even a new one.

Tell me how to reduce the size of buttons, tabs, and everything else BUT the fonts in my browsers. All of them have been affected. I've exhausted all of the normal "look in Settings and use your brain" options.

I use the Windows registry FontSubstitutes (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes) to replace system fonts like Segoe UI with other fonts. It takes a lot of work to get Windows itself to respect these options, to the extent that I have to make it believe Segoe UI isn't present by modifying a different registry location (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts).

However, Firefox does not respect the FontSubstitutes settings. Based on a previous post here, this is something it did prior to Firefox 89, but has stopped doing.

An ideal solution would be a way for Firefox to correctly read my FontSubstitutes settings. An acceptable workaround would be a way to provide Segoe UI for Firefox to use while still preventing its use in other applications. (I know that, for instance, Adobe Photoshop allows users to install fonts to Photoshop itself, bypassing the system fonts folder entirely.)

Subject says it all, but it seems to occur with any site, anytime I try to open more than three or four tabs (ctrl-clicking links on a forum, for example) my Firefox instance grinds to a halt and starts consuming most of my CPU (Ryzen 5 3600).

I've tried turning off Firefox's various protections. I tried troubleshooting (formerly "safe") mode, and the problem isn't as bad but is still present as far as I can tell. The only extension I can think that would be making it worse is Tree Style Tab, but I don't know enough about interpreting Firefox profiles to verify.

The only reason I consider this odd is because doing the same thing in Chrome doesn't have this issue on this same device. If I open many tabs quickly, Chrome itself is still responsive. Those newly opened tabs may take a while to load and become interactive, but it doesn't affect the rest of the application. I pay my ISP for gigabit DSL, and as far as I can tell that is roughly what I get. In my case, Firefox doesn't behave this way.

Firefox just updated itself to v106 (x64). Opening Microsoft outlook web mail (https://outlook.office.com/mail/) gives me the opening envelope between 5 & 10 times, then an error screen that says "multiple redirects detected". Hitting the 'refresh' link works fine, and no trouble after that, so maybe a sign in issue? Seems to be a new problem; didn't happen yesterday.

for new file types the option to save the default behaviour for future downloads is no longer avaliable for me. Also, the option to set in "Settings -> General -> Files and Applications" does not show any of the new file types.

I've tried re-installing firefox, as well as refreshing but still the same results.

Over the last five hours, I have gotten 27 emails from Firefox Monitor for this data breach, for the same email address. I have already marked the breach as resolved in Monitor but I keep getting emails. Is there anything I can do about it?

When I try to log in to any Google "Ecosystem" (i.e Gmail, Youtube etc.) I see it (check screenshot below). I'll use Firefox Developer Edition. In vanilla Firefox and other browsers, everything works as usual.

Hello For a few days now, every time I go to youtube the page appears almost completely blank (see screenshot). I've tried disabling all my extensions and go in troubleshoot mode but it still does not work. When I try removing youtube storage from firefox settings "manage cookies and site data" and saving, data of the same size is still there when I open the storage manager again. The only thing that seems to work is going into a private window but since I have to keep signing in each time it is painful especially with google MFA. Please help.

Thank you

I don't know why the page https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es is marked as insecure in Firefox. I tried in Chrome, Edge, IE... and the page is marked as secure, the certificate is recognized.

I attach screen captures of Firefox and Edge examples.

I've the security.enterprise_roots.enabled setting enabled.

If I check for Firefox error details, I see (auto-translated to english): https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es The issuer of the other end's certificate is not recognized. Strict HTTP transport security: false Setting HTTP public keys: false

Hi,

I could see a adclick somehow added to my Firefox app on iPhone iOS 17. I don’t see any actual bookmarks exist but don’t know how this reference still exist and how to remove it?

Please refer the screenshot, appreciate any and all the help to understand and remove this adclick.

Best Regards Barrie
