Diễn đàn hỗ trợ Firefox

Every day when I sign in to Firefox I receive this email message, and I don't know why. I have been signing into Firefox for a few years. I don't remember when this started and I'm not sure if this is just your way of authenticating that I am me or not. Please explain this email I receive from accounts@firefox.com. I have changed my password many times so that can't be it, at least I don't think that's it.

Thank you for your help Rhonda

I recently installed windows on a new solid state hard drive, and did a fresh install of firefox, but I forgot to manually backup my bookmarks. The old install is still on the old windows hard drive, is there a way for me to move them onto the new install? I'd prefer to not have to rebuild the whole list from scratch!

How are my bookmarks stored when synced between devices? Are my bookmarks encrypted as well as my passwords/credit card info? This is from the Mozilla page regarding encryption:

"Your encryption key remains a secret, only known to you and your authorized devices." and "We store your encrypted data on our servers so we can’t read it."

I just wanted to make sure this also applies to bookmarks before I import all of mine.

Thanks for any help!

In the current Version of Firefox the input field is set to the wrong filetype if select an csv file.

Open with Chrome and Firefox. Chrome set the file type to text/csv Firefox to "application/vnd.ms-excel"

Working example open the consoel to see the output: https://codepen.io/GrizzlyStu/pen/YzjZjez

I pressed some button that is on the left side of the keyboard, I didn't see what it was, and after that my url bar for some reason has a space that leaves the text on the right after that

For the past week Firefox has been opening Youtube in dark when for the last decade I've been using light. Every time I change to light it works for that tab, if I open a new tab and load Youtube it opens in dark appearance. When I change to light and then click my avatar in the top right of Youtube it's still states I'm in dark when it's in light.

Why doesn't the light appearance stay? I've cleared cookies and that doesn't seem to work. It's also specific to Firefox, this doesn't happen in Microsoft Edge.

As of today (worked yesterday and previously), I cant access Youtube using Firefox with my ProtonVPN on. Chrome+ProtonVPN=yes Firefox+ProtonVPN=no Firefox withoutVPN=yes Can I fix this in Firefox settings or ProtonVPN settings. I have contacted both.

In reference to my previous post ( https://support.mozilla.org/en-US/questions/1382198?page=1 ) I have noticed that the "jumping while scrolling" in the Facebook News feed has returned after a couple of months of proper behavior. Ver. 108.0.2 It's not as bad as it was but it seems to be getting worse.

Is the circus back in town?

Am I going to have to move back to Chrome again ?? >:-(

I have my setting to ask me what to do with files, pdf , whether open or download i have it all set to ask it asks , it opens them in firefox but still downloads them to my computer. i don't want them to download , i'm never sure if they are safe how i stop stop auto download This has only been in the last few updates this began

I have run Firefox for years on up to 4 PCs at once, everything has always synced and screens all look the same. Recently one laptop lost the addon extension icons in the Firefox toolbar. They remain on all other installations. I have tried uninstalling Firefox and installing an earlier build, and also the latest Beta build with no luck. All extensions show as installed and activated. I have copied the Profile from another laptop. I have of course done a reset. Any other suggestions?

Title. Whenever I open Firefox, the window will appear shortly after, but it will take around a minute for websites to load. This applies to both tabs from older sessions and opening new tabs. It doesn't matter whether I've just booted up, or if I've been running for half an hour. I've tried disabling all extensions, but that hasn't fixed anything. I am running Linux Mint 21.1 Cinnamon on my Gaming Laptop. Specs shouldn't be an issue. ANY HELP WOULD BE MUCH APPRECIATED!

I expect the back button to return to the previous page visited, but too often the button either doesn't respond at all or a right click is required to view the page history. Is there something I need to do get the original function of the back button that I thought was universal in most browsers?

I wanted to use sync to transfer my tabs from my previous MacBook to my new MacBook. I reset the previous MacBook and now when I login to the new one, sync does not show any of my previous tabs.

Good morning, Recently I discovered there are two maps called "Andere bladwijzers" in my Firefox browser. I deleted a submap in the second map and noticed this submap had also disappeared in the first map. Is there something I must do or can I leave these two large maps as it is? Thanking you in advance for your reply. With kind regards, Ed Schijf, the Netherlands

I asked a question to add details after an answer but when I have an error when I click to the "Post a Reply" button.

Hi, I just replaced my SSD (Samsung 960EVO m.2 250Gb) for a larger/faster SSD (Samsung 980 m.2 1Tb) . I'm on Windows 10 and have 32Mb Ram. Firefox is now very slow on some websites (not all).

This example is typical and has occured on multiple sites. To test and compare, I copied the URL, created a new tab in Firefox, then Paste and Go. I timed this 3 times and each time was 30 seconds. I Pasted the same into Chrome and Edge and each time it was instant. https://savingschampion.co.uk/best-buys/personal/easy-access-accounts

On my previous SSD, there was never an issue of any lag on any site.

BBC.co.uk/news is fine, as are several other sites. Does anyone have any idea what's happening? This is making Firefox unworkable for me, so unless I can fix the issue, I will have to move permanently to Chrome or Edge. That would be a shame after many years with Firefox.

Thank you in advance.

I have searched the "Knowledge Base" to no avail--no solutions, just others with the same problem. Every day a handful of fresh Trouble Reports pop up on my desktop, even though Firefox is not even running (as verified through the Windows Task Manager). It got so bad, I uninstalled/reinstalled and the problem persists. Otherwise, the browser works fine. My expertise lies outside trying to decipher arcane strings of data buried deep in the bowels of my computer, and frankly I should not have to start hiking up a steep learning curve just to get this to stop. I should add, I have been a fiercely loyal Firefox user since its inception.

I'm not super happy about sharing internal data with the rest of the universe, but have done so anyway in hopes we can get the madness to stop!
