A recent update to the Firefox browser is causing problems for some people. If you use Firefox, you might have noticed issues yourself. These problems mainly affect two areas: the toolbar buttons and the browser tabs. Many users have shared their experiences, showing that this is a widespread issue. You are not alone in facing this.
The situation is undoubtedly frustrating. Your browser is a key tool for work, school, and personal tasks. When it does not work correctly, it can disrupt your entire day. This guide will explain the problems in simple terms. It will also offer some temporary solutions you can try while the Firefox development team works on a permanent fix.

The Problem with Unresponsive Toolbars
One of the main issues is with the browser’s toolbar. This is the area at the top of the browser that holds the address bar, as well as the back, forward, and reload buttons. Users report that this entire section can suddenly stop working.
When this glitch happens, you cannot click on any of the buttons. You cannot type a new web address into the address bar. The toolbar does not even react when you move your mouse over it. This freeze can last for more than ten minutes, making the browser very difficult to use. During this time, the actual webpage you are viewing might still work, but you cannot navigate away from it using the toolbar.
Some people have noticed a pattern. The bug can appear after you reload a tab and quickly switch to another tab before the first one finishes loading. It seems this quick action can confuse the browser, causing the toolbar to lock up. This can happen even on a fresh installation of Firefox with no add-ons or extensions, which shows the problem is with the browser itself.
Strange Behavior with Browser Tabs
The second major problem involves the browser tabs. Tabs are a core feature for managing multiple websites at once. The recent update has caused several different and confusing issues with them.
- Disappearing Tabs: Some users have found that all their open tabs suddenly vanish. One moment they have many tabs open, and the next, they are all gone.
- Blank Tabs: In other cases, the tabs do not disappear completely. Instead, they turn into blank pages. The tab is still there, but the website content is gone, replaced by an empty screen.
- Lost Tab History: Normally, if your browser closes, you can restore your previous session and get all your tabs back. However, people are reporting that this feature sometimes fails. The browser’s memory of their previous tabs is completely gone.
These tab-related glitches are a serious problem. Many people keep important work or research spread across multiple tabs. Losing them all at once can mean losing hours of progress. Trying common fixes like restarting Firefox in safe mode or creating a new user profile has not worked for most people experiencing these issues.
What Is Causing These Glitches?
The Firefox developers are investigating the root cause. Early findings shared in technical forums point to a specific piece of code. When you move a tab from one position to another, the browser adds a temporary attribute to it called “movingtab.” The problem seems to be that this attribute sometimes gets stuck. The browser still thinks a tab is moving even after the action is complete. This leftover instruction appears to cause the conflict that freezes the toolbar.
Every time the toolbar freezes, a specific error message about a “JSProcessActor” appears in the browser’s technical console. This clue is helping developers narrow down the search for a solution. Knowing the potential cause is the first step toward creating a reliable fix.
What You Can Do Right Now
While waiting for an official update from Mozilla, the creators of Firefox, there are a few things you can try. These are not permanent fixes, but they may help you regain control of your browser when the glitches occur.
Use Keyboard Shortcuts
Even when the toolbar buttons are frozen, keyboard shortcuts usually still work. This is very helpful. You can continue to navigate using your keyboard.
- Ctrl + L (or Cmd + L on Mac) to select the address bar.
- Ctrl + R (or Cmd + R on Mac) to reload the page.
- Alt + Left Arrow (or Cmd + Left Arrow on Mac) to go back.
- Alt + Right Arrow (or Cmd + Right Arrow on Mac) to go forward.
Restart Through the Profiles Page
One user found a temporary workaround that can unfreeze the browser.
- Open a new tab and type about:profiles into the address bar, then press Enter.
- This page shows your Firefox user profiles. Find the option to “Restart normally.”
- Clicking this will restart Firefox and may resolve the toolbar freeze for a while.
Move the Affected Tab
Sometimes, interacting with the tabs can jolt the toolbar back to life. Try clicking and dragging the frozen tab to a new position in the tab bar. This action can sometimes clear the error and make the toolbar responsive again.
A Note on the Missing Translate Function
Separately, some people have been confused about the “Translate page” feature. On devices with smaller screens, this button may seem to be missing from its usual spot in the address bar. The function has not been removed. Instead, it has been moved. On smaller screens, a banner will appear at the bottom of the page offering to translate it. This change is part of the update and is not a bug.
The latest Firefox update has clearly caused significant issues for many. The developers are aware of the problems and are working to resolve them. For now, using the workarounds mentioned above may help you manage the situation. We will continue to monitor for an official fix and provide updates as they become available.
