I've noticed this issue happening randomly, some of my toolbar bookmarks listed on the sidebar just up and disappear from view. As if they were never there. But I know they're still saved because when I click to Manage Bookmarks and check them there, they show up fine. The toolbar just randomly hides them for whatever reason, and I can only fix it by closing Firefox and opening it again.

I'm on the current version. I remember accessing about:support and clicking on Verify Integrity while trying troubleshoot some other issue, but don't know if that could've caused it though.

I've been attempting to use FIDO2 w/ PIN support to log into Okta. This occurs with a pre-registered security key (Yubikey 5C NFC on most recent firmware) that has a PIN already configured. This key works on all other browsers and devices without trouble. Firefox is unresponsive to Yubikey interaction after the notice "Touch your security key to continue with <company>.okta.com" and will eventually time out if I do not cancel.

On the other hand, I can register a new security key on Okta through Firefox on this device. When I go through the registration workflow, Firefox is responsive to all interactions, allowing me to enter my PIN and complete registration.

I have been able to replicate this issue on other computers and with a different user / security key.

In macOS you can set up a global keyboard shortcut for the Move Window to Right Side of Screen command via System Settings > Keyboard > Keyboard Shortcuts.... In most apps that support the Move Window to... commands, this will simply move the window to the desired side of the screen when the key combo is pressed.

However, in Firefox the key combo will start the animation as normal but the window will then bounce back to its original location. It's only when the command is activated via a keyboard shortcut that it does the bounce back behavior, though; the command works as intended when activated from the Window menu in the menu bar or from Option + green button in the top left of the window.

The key combo I set up was Shift + Option + Command + Right Arrow, but I've also tried a couple of different key combos and they all did the same bounce back behavior. I've tried it on machines with different versions of macOS (Sonoma beta and Ventura) with the same result. The bounce back behavior also effects the Move Window to Left Side of Screen command.

I'm looking at a web-page in a specifc firefox window or tab. When I want to leave it, I'll "delete" the tab" or the window by clicking the "x". BUT, often, I want to have ALL the cookies of this web-site deleted. - Perhaps a right-click on the "x" should pop-up a window saying: [do you want to clear all cookies for "abc.de" ] - and then I click "yes", and I'm done!!! Any more complex solution as spelled-out here in support is not a good solution; we need a "one-click" method.

Thanks, I hope a Firefox developer is listening.

I received a message from Fire Fox that I should update. Now I have 2 Fire Fox icons and I need to know how to determine which one to delete. Then I need to know how to transfer my favorites and history to the one I keep. They both show favorites and history. I'm a rookie at this so if you can explain step by step it would help, thanks.

I've been noticing for the last month that after a few hours in a browser window, I'll suddenly have a pinned tab for some random website. Some for promotional things, others in languages I don't understand, etc. At first I downloaded a webpage blocker, blocked the ones that were pinned, and deleted the tabs. However, after a short while (an hour or two) they would appear again in pinned tabs only this time it would say website blocked.

I uninstalled and reinstalled firefox in hopes that would solve the issue, but it is still happening. I unpin the tabs and delete them immediately after I notice them, but they keep appearing. I really like using Firefox and use it often for work, but I'm concerned for my personal and work security. What should I do?

Hello.. I turn on my laptop, start firefox and all my bookmarks are gone... I wasnt log in for very long time during using firefox and what I can do now to get back my VERY IMPORTANT bookmarks?

The solution I had posted here - [https://support.mozilla.org/en-US/que.../1343170] no longer works (Firefox Developer Edition 115.0b9).

Having inspected [https://searchfox.org/mozilla-release.../popup.css] I am still unable to find a solution to remove the box shadow from content area context menus.

Im having an issue with firefox where the tabs keep crashing i cant go a day without the tabs crashing 50-60 times or even the browser itself crashing, ive tried relaunching without addons, with troubleshoot mode on, firefox on a different drive but, it is still crashing, i looked at the error logs and if im reading it right (im not at all knowledgeable in how to debug software) it is always crashing at a point where the module is none and the signature is an address value, I put screen shots of the error reports showing the numerous crashes, before I think its a hardware issue like a bad stick of ram (which i dont think cause i ran memtest 86 test overnight with no errors), a faulty motherboard, or god forbid a faulty cpu and start firing the parts cannon at the issue i want to rule out any software angles for the problem.

Firefox 115 it´s not decoding video and has high CPU Usage specially in full HD video streaming in twitch. I noticed this problem since 114 version. I upload two SS one from Firefox and one from edge.

I've tried the F9 Keyboard Shortcut, I've tried other Reader Add-Ons, this function simply doesn't work with Outlook. Either when in the Inbox, or with an opened Email. Anyone else encounter this?

Anyone know of a solution to making this work?

On a VERY side note: Here is my 1st initial text, when I believed the problem was about Firefox Add-Ons (I now have discovered it's not about the Add-Ons, it's the about the Reader View function). << When double-clicking on an Email, on the Outlook web site (https://outlook.office.com/mail/), the Email opens in a new window. When the new Window is opened, doesn't work.

When I click on Firefox's "Enhanced Tracking Protection" Icon and disable it, then the Extensions work. What's even weirder, is the behavior is the same for the REVERSE (if the Enhanced Protection is Disabled, the Keyboard Shortcut doesn't work until I "ENABLE" the Enhanced Protection).

Is there a setting in about:config that can return the functionality of Add-Ons (Extensions)?

On a side note, I found a setting to force the New Emails to Open in a new Tab instead of a new Window. The same bevaior is replicated, No improvement has been shown on that front. browser.link.open_newwindow.restriction = 0 >>
