Firefox Support Forum

trying to restore previous settings i have accidentally created multiple copy's of bookmarks and folders. many have more than 10 copy's and i now have over 400 000 bookmarks. is there any quick way to delete the copys of bookmarks?

Picture in Picture is an awesome feature and i love that Firefox comes with it by default.

However I do wish for one thing. So we can lock and "click through" the picture in picture, instead of our mice being able to click it by mistake when doing other things (such as grinding on an MMO or something.)

Is there any way to get these options in the near future? It'd be great to play some games when watching a video during slow times! Thank you!

In Firefox, after a reboot, how can I re open my previouse sessions?

Originally I had quite a lot of open browsers & tabs. Then I needed to do a reboot, and now I've lost those previouse sessions.

Usually I just open firefox, and this opens one browser, and then all of my previous browser, and tab reopen, but this time firefox crashed, and its popup said it needed to restart, but it would re-open my previous browser and tab, but it didnt.

After following the usuall firefox help giudes, it still wouldn't re open my previouse sessions. Now if I ask it to open my previouse sessions, it just opens the recent help giudes, and not anything before the crash.

So is there a backup file of myu missing sessions that I can roll back to?

Hi,

am running firefox 127.0.1 on a windows 11 desktop. Numerous sites that use a captcha to login fail. In other words, the captcha never loads and I cannot login to those sites. Such sites include teamfaderpro, Coursera, and bandcamp. All logins fail as the captcha is required to be passed prior to logging in, but the captcha never appears and so when I try to log in, nothing happens and I cannot login.

I have tried the above same sites on the Edge browser and have no such issue, the captcha shows and I can login.

Just FYI, the agent switcher setting change recommended by others previously is not suitable. When I tried that fix I was unable to access a considerable percentage of the internet due to some cloudflare issue, so the agent switcher setting is not an option. So far, I have tried all recommended settings to fix this issue and nothing has worked.

I am surprised no one else is having this issue.

Any help is appreciated, or at least inform google/mozilla about this issue as it has been ongoing (on and off) for me for many months. And yes, this problem is persistent for me at the moment, it remains despite rebooting windows, despite clearing cookies and cache (which I have set to automatically delete when exiting firefox).

I would like to create bookmark folders WITHIN a bookmark folder. Example: I search the American South, so I have a SOUTH bookmark. But within that bookmark, I would like to have a subfolder for each state. Please help!

I use Firefox with a VPN. I also use the Chameleon extension to alter my fingerprint. When I log into Messenger.com it asks if this is me and gives my actual, physical location. I've checked in settings under location and it doesn't show any sites requesting my location. I have it open in one of the tabs where it's showing my location. I have block all location requests checked. How can I get Firefox to not show my physical location?

Also on this page, it gives I'm using Firefox and the OS I'm using. Both are supposed to be changed for fingerprinting protection.

This looks like it could be a big security loophole. Any help is appreciated.

Every so often while browsing, for several FF versions, now, hover card functionality on some sites will simply stop working, even after a complete browser restart. Eventually the cards come back on their own.

Not a crucial issue, frankly, but an annoying one, and I'd like to know why it keeps happening and what can be done to stop it.

I am finding more and more sites that I regularly go to are no longer working on firefox. One site was because HTML5 apparently does not work on firefox. But others I don't know about why are no longer working on firefox. I thought it might be streaming related but just today I could not access one of my banks on firefox, and I tried many times, but had no problem signing on using Chrome.

I have a full current installation of Firefox, after a struggle to get Bing off my system (Win11) I briefly got back to a personalized start page which had a large text "Firefox" heading and allowed me to add apps in small boxes and click to start an app. That page has disappeared and all I get is the ad referred to in the title. How can I replace the ad with the page I can load with app icons?

Right now i love my HDR content in most scenarios, except on a few sites where its just bad. Is it possible to be able to block it on certain sites where you dont want to apply it?

Hello,

Relevant system referenced below:

MacBook Pro 2021 Mac OS 14.5 Firefox 126.0.1 (64-bit) Carbon Copy Cloner 6.1.11 (7673)

I have a case of vanishing bookmarks. I quit Firefox last evening with command-Q as I’ve done a thousand times before. When I launched it this morning I was greeted with Firefox with an empty Bookmarks Toolbar and “Getting started” message. I opened a Manage Bookmarks window and everything there was empty too. I found, as well, that all of my saved UIDs and passwords were gone except for three, two of which I haven’t used in months. Weird.

Next I opened Firefox Help and found information about Troubleshooting Mode; I restarted in troubleshooting mode but nothing had changed. After restarting in normal mode, I tried Restoring Bookmarks; I chose Manage Bookmarks from the dropdown and then clicked the button in the Library window. Restore showed only one file and it was created today with only 14 items. Selecting Choose File… showed Desktop with Old Firefox Data highlighted. In that folder was only w34y3u9y…628 folder. From there I selected bookmarkbackups and the only file there was bookmarks-2024-06-06_11…lz4, a file created at 3:33 today. I found the key4.db file and it was created at 3:33 today.

I have Carbon Copy Cloner and use it for a weekly backup to a remote SSD drive. There are a year's-worth or so of weekly backups on that device. I tried trashing Firefox and reinstalling it from last week’s backup. While this worked, it didn’t solve the issue; it was still like a fresh copy of Firefox with no bookmarks.

I’m hopeful that I can restore the bulk of the lost bookmarks from CCC but I have no clue as to which files/folders to restore and I don’t want to guess. If you think this is possible, please tell me which files or folders to replace. Should I delete the files to be replaced from the current system and if so where are they located? I’m comfortable using Terminal for basic purposes but need explicit directions for entering commands and navigating to locations or files.

Thanks for your time,

David

Hello, I'm a web developer. I'm using the Firefox Developer Edition and currently working on a project that requires caret manipulation. I have this function right here that fetches the caret's client rect: ``` function getCaretRect(): DOMRect | null {

 const sel = window.getSelection()
 if (!sel || sel.rangeCount === 0) return null

 const range = sel.getRangeAt(0)
 const rects = range.getClientRects()
 if (rects.length === 0) return null

 return rects[0]

} ``` Here is where the issue arises. Suppose I have a contenteditable div with two line breaks (no new lines), and the second line is smaller than the first one. If the caret is positioned somewhere that is further than the end of the second line, and I press the down arrow key, then left, for some reason the caret rect I get has all values set to zero, like this: `{ x: 0, y: 0, width: 0, height: 0, top: 0, right: 0, bottom: 0, left: 0 }` I will add an image to explain further.

I don't have this issue on Chromium based browsers, but cross browser support is important for me.

There is one more issue to do with caret manipulation which is how contenteditable divs are handled. On a Chromium based browser, if I have a parent div that's contenteditable, then another div that's not contenteditable (contenteditable="false" explicitly), then two children divs which are both contenteditable (or more), I can navigate through the divs freely using the arrow keys and focus is managed better alongside event handlers. This is not present on Firefox, however.

If this is not the right place to ask for help then please guide me where is more suitable.

Im using Ubuntu 22.04 LTS Intel cpu I7 9th gen NVIDIA gpu but i disabled it My problem is that the Picture in Picture mode isnt sticky if i press anything it vanishes from view.

Hi,

ist the famous and great Mozilla FireFox Developer team aware of the issue and is working on it?

I am happey to describe in more detail if required. thx

I can no longer use my camera on firefox, firefox displayed some message about camera when we were trying to chat, but I missed it, I have granted relevant permissions on the site, that we use reularly. The camera icon on the address bar appears red, and I noticed that in Windows security, it lists firefox access requests, but shows no way to grant these requests.

I am not tech minded so please if anyone could keep it simple, I would appreciate it.

I enter my username & password and nothing happens. This occurs when I use Dashlane AND also if I enter username & password manually.

I can access my account successfully using Edge.

Hi,

I'm switching from Edge and have a frustrating issue.

In Edge I am very used to having separate behaviour for links with left and middle click.

i.e. from Gmail, if I left click a link it opens in a new tab and switches to the tab, if I middle click a link it opens in a new tab but stays on the current tab

In Firefox both seem to be controlled by the single setting.

I have looked in about:config and tried changing a few flags but cannot seem to find a combination that works how I want it.

Can anyone help?

This is a real dealbreaker for me and I will switch back if there's no solution :(

TIA
