Firefox Community Forum

As mentioned, When google email account is open, opening another operative window, firefox automatically closes the email account. Why is this ? This looks to me as a possible bug or IE security program intervening to avoid cross connectivity and security violations between other opened windows. Correct ? This is annoying as an R&D engineer it is common to work with several opened windows. Any solutions or fixes ? rJ

I cannot log into Facebook with my Firefox browser. Even though the username and password are entered correctly, the login freezes and I cannot proceed. I am able to access the site on other devices. On my laptop, I deleted all cookies, history, and cache as recommended. I am able to log in to Instagram on this device. Coincidental to this problem: when I try to view video on newyorktimes.com, the browser freezes. I cannot view content in other open tabs and must reboot the browser.

I've always used firefox

Recently it seems to me that a lot of sites don't seem to recognise me, so I have to do multi step logins.

Paypal for instance. I don't save the password, I type it in each time, but now it insists on sending me an SMS in addition

My guess is that FF is deleting some cookies that I'd rather it didn't. What can I do?

Thanks

Can someone advise me on this?

When I'm on my phone and signed into my Firefox I want to be able to send tabs to my desktop. I'll click the three dots on my Samsung 20fe, click share, and click send to device. My p.c. is listed and when i click on it, a box pop's up and says "tab sent. I don't know where it's going, but it's not making it to my desk top. I've tried logging out and logging back in. on both devises

Hi

I cannot reactivate spell check as I type, with English dictionary and the thick box ticked. Previously I could not get rid of spell check in my 2nd language (Turkish) but as I have managed, now I cannot restore spell check in English.

Can anyone help please?

Should I delete and reinstall Firefox? If I do will I lose my bookmarks?

Thanks in adance to all.

I just upgraded my Dell desktop computer -- Win 11 and some other hardware tweaks. Everything is fine -- but an old problem that was resolved some time ago in this forum has reemerged. My mouse wheel does not scroll properly at all with Google Calendar. I recall a simple solution on this forum that worked perfectly a few years ago when I originally set up the computer. It has apparently been removed, and I can not find anything to resolve the matter. Does anyone recall the secret formula? Is it hidden away somewhere? The scrolling is so convenient, and the instinct is hard to break.

Why can't Firefox open .mht email extensions within its default browser? It has never done so to my knowledge. They always point to Internet Explorer or Microsoft Edge.

Often an email may not display images correctly and the ability to open them in a web browser is offered, "If there are problems with how this message is displayed, click here to view it in a web browser." This is certainly a development addition when people view their Gmail from Firefox or use Outlook. Not everybody uses APPS. People who don't want Microsoft Edge watching every move they make have made effective permanent changes in removing the deep embedded PUP by Microsoft.

Firefox version: 148.0

I am using Firefox on a W11 64 desktop. Until recently (the most recent upgrade, I think) all worked well. But since then although the relevant box is ticked in settings (aboutpreferences general), on opening Firefox the tabs from the preceding session are NOT restored. This is extremely inconvenient.

Have any others found this same problem? Any work arounds?

i had multiple tabs set up in multiple groups and i used yo restore these every day when i rebooted every morning and all that is lost to me now. i can see that the groups are there but can no longer use them. how can i uninstall mozilla firefox

bold textI have created a new profile, uninstalled Firefox and reinstalled, flushed the DNS, always deleted cookies et al on closing. When I try and sign on I get a msg saying site unavailable, but when I go to the laptop sign on without any problems. Also on my desktop if I use Edge to logon to the site I am successful.
