I had a laptop Windows 7 laptop that fried itself, a puff of grey smoke came out of the air vent on the side of the laptop and now I have a Windows 10 Pro laptop. I saved the file "Old Firefox Data". Were do I insert these two files (folders) in Firefox to restore it back to it's condition before the new laptop?

Old Firefox Data 41n7x9r4.default-release-1679350213712 eer77r96.default-release

Thanks, Richard Germain

Hello, when I open the Firefox browser from my taskbar it does not open as a full browser page as Image 3.

I have to click on the full-screen icon twice to get it open in full screen as in Image 4.

Please can you help?

on some websites it says -1 tells Firefox to automatically determine the size of the cache based on your physical disk and setting it to 0 would effectively disable any disk cache entrys.

so are this informations true and if not, how do i still let firefox automatically determine the size of the cache based on my physical disk?

Updated FF Tuesday evening and noticed first on Wednesday when unable to log in to my Tesco food website. Access not allowed from this server or some such. I tried to use the Tesco feedback form and then got alerts both from Avast (saying it was infected) followed by FF refusal to connect. I tried safe mode and removing and adding FF.exe to Avast without change. I reset FF without change. MS Edge allowed access to all these sites without a murmur.

Today i can get to Tesco main site but still not Feedback.

Also my local Synolgy NAS now has a warning that it is dangerous to access from FF. Nothing has been changed in its set up or security. I can and do override and access everything

Something in the Tuesday update has caused this clash. I did think at one point I also saw 120.0.1 being offered but that may have been my confusion.

Happy user of FF fro many years and do not want to change.

I accidentally closed both of my Firefox windows with an "x" and the rebooted my computer. After the reboot there is nothing under "History"->"Recently closed windows" and "Recently closed tabs". Is there any way to get my windows back?

I wanted to make a lengthy post on a website today, but I accidentally hit CTRL + R twice which bypassed the "This page is asking you to confirm that you want to leave — information you’ve entered may not be saved." safety net. Is there a way to deliberately disable any and all refresh shortcuts and buttons when a safety net shows up, so my buttery fingers don't ruin my day to it's absolute maximum?

I want safety nets to be deliberately annoying.

I need to turn off use Firefox email mask... I can't STAND being prompted to use Firefox email mask but I can't find a way to turn off that prompt.

JUST STOP THAT! It's infuriating that you're trying to force me to use something I DO NOT WANT!

Upto Firefox v115 this website working fine. after update this website table display right side end. not in position. checked in other browser. working fine in chrome. what to do?. need solution. thank you.

Later version refuses to connect to my modem, and goes into security web mode. This modem uses HTTP/HTTPS for access, i.e., connects directly it's IP address, then the user enters a username and password. At that point, the the modem switches to HTTPS for control.

With this recent update, there is NO WAY to access the modem for any work, or upgrade the HTTPS certificate on the modem. This is a BUG.

What should happen is that if the web site will accept a HTTP connection, Firefox should NOT refuse connection or test for security issues UNTIL the user or the device switches to HTTPS.

As an aside, I've used Firefox on this Zywall modem for years until recently.

When attempting to update my Mozilla account from my Firefox settings, I was unable to add my secondary email address because of an error message stating that the secondary email account exists...

Repeating this action in case of a bug resulted in being locked out of that particular window.

I have no idea what that error message means, nor how to circumnavigate it. Please help!

Thanks, MGB

I can log into preply.com with Chrome and Edge, but always have problems with Firefox. I was able to log in once, but after that, I can't log back in.

Recently I had to reinstall Windows, and saw the opportunity to try getting this to work. Installed Firefox, but *before* I logged into Mozilla Sync (so I'm working with a 100% fresh installation with no history of having Firefox installed) I tried to log into preply.com. It worked. Then, I log myself out and try to log in again, and once more, I can't log back in. I'm attaching a screenshot of what I see when I try. Please note -- I have no bookmarks, no extensions, no addons, no browser history. Everything is tabula rasa.

I found this page:

https://support.mozilla.org/en-US/kb/fix-login-issues-on-websites-require-passwords

and followed it to the letter, meticulously, to no avail. I still can't log into the site with Firefox. Chrome and Edge, yes. Firefox no. I only have Edge because I can't uninstall it. I only have Chrome for situations like this, where Firefox doesn't work. Firefox is my main browser, and I really, really would like to figure out what's happening. I can't understand how this problem persists when the browser is freshly installed; I haven't imported one bit of data yet from my sync account.

Can someone more experienced than me please help?

Oddball minor problem I've encountered on a recent update of Firefox, but also I switched keyboards at the same time, so I'm not sure which causing the problem. I'm on a PC, using an MSI keyboard. Ctrl and Shift keys all work, the ONLY combination that doesn't work is (left) Ctrl + (left)Shift + P. Other Ctrl + Shift key combinations work. If I hold the right Ctrl and either shift, P works fine. If I hold the right Ctrl and the right Shift, P works fine. (left) Ctrl + (left)Shift + any other key shortcut in Firefox or elsewhere works, it's ONLY the P shortcut and only in Firefox and only with the left two ctrl+shift combo that doesn't work.

Any ideas on what is causing this and how to fix it?

As of yesterday when I was running v119.0 I was able to screen capture streaming content from Hulu/Netflix etc, this morning after upgrading to v120.0 overnight, that capability is now lost. Video and still captures are just a black screen. Please fix!

I am trying to log in to the Tesco retail site, and get this message: Access Denied You don't have permission to access "http://www.tesco.com/account/login/en-GB?" on this server. Reference #18.26cc19b8.1700734342.438f9dd8 This is a new problem - it was working fine a week ago, and I have made no intentional changes to the Firefox settings. I went to the Settings: Enhanced Tracking Protection, changed it to Standard, and added the Tesco site as an exception (this was following the advice on some other "Access Denied" posts) but it made no difference - I still can't log in. Everything works fine on Chrome, but I would prefer to keep using Firefox if possible. Any suggestions? Thanks
