Firefox Support Forum

I accidentally hid the menu bar and toolbars (with an accidental keyboard shortcut, I think), and when I re-enabled them, now the tab bar is above the location bar instead of right above the content windows. How do I move it back? I can't find the "browser.tabs.onTop" setting in about:config, or any check box in the View menu, settings, etc.

I'm using Firefox 119.0.1 on Ubuntu Linux.

Thanks!

Hello,

For the past couple of months I have been experiences tab crashes every day when watching a specific streaming service called wowtv, all my other tabs are fine and work flawlessly. Additionally, after restoring the tab or opening it anew it works again for the next few hours until the next crash occurs. Netflix, disney+ and others work fine as well. So far I have tried reinstalling firefox as well as try other browsers where said issue doesn't occur. I sadly don't have the error message or anything but the video freezes just before crashing, neither closing all tabs 'nor trying an older firefox version fixed it for me.

With regards,

Marcinathi

Since Firefox update 19.0,1 flightradar website freezes when I click on an aircraft...

Using brave browser no problems.

windows 10 laptop with windows security all updated.

For the past few days, Firefox has been freezing up. By playing around with it, I've found that it's still functioning, but it ceases to update visually. I'm not having the same issues with any other program on my PC, I don't see the icon to update Firefox, and I've restarted my PC a few times along the way.

When this happens, it's not just website contents that freeze, but Firefox's UI as well. Hovering a tab doesn't highlight it. Clicking the hamburger doesn't appear to open the menu. Etc...

If I have a video playing when this happens, I will continue to hear it, but the frame the video is on stays in place.

If I click on another open tab, it will still show me the tab it visually froze on, but if I end Firefox with Windows Task Manager & reopen it, the session saves the tab switch, so it's still taking mouse inputs. I've been able to do similar with keyboard inputs by clicking on the address bar and entering a new URL. I don't see anything as I type it, but after using Task Manager to close and reopen Firefox, the site I entered is there.

I can switch between open Firefox windows when this happens without issue, even on the same monitor, and if I pull up something else in front of Firefox and then switch to Firefox it will still display what was last visible in that Firefox window while the bug is occurring.

I have tried disabling add-ons, and actually found that disabling some of them made it happen *more* frequently, not less. Privacy Badger, Auto Tab Discard, & Ad Nauseum specifically. Switching from Ad Nauseum to AdBlock Plus or uBlock Origin neither increases nor decreases the frequency. My other add-ons, like Duplicate Tabs Closer, haven't had any effects on frequency that I can see. With all of my Add-ons disabled, Task Manager shows double the number of Firefox processes.

I tried to clear my history, but I can only select my last 1 hour of history, as clicking on the dropdown box to select another duration will cause the problem to occur & I can't see the other options in the box to select a longer option. The dropdown to select a topic for this question has the same issue.

These are some actions that risk causing the bug to start, but aren't 100% reproducible, and the list is not exhaustive:

• Trying to click & drag to pull a tab into becoming its own window or to move the tab into another window. (Firefox does not save this movement if it causes the bug, so closing and reopening it will keep the tab in the window it was already in.) This seems to work fine for some sites, but specifically tends to break if it's a YouTube tab.
• Mid-clicking to open a link in a new tab, if done on several links in a row
• Clicking on a UI element, like the hamburger button
• Right clicking on an image and selecting "copy"
• Right clicking within Firefox
• Opening Firefox

I have not seen the bug occur at any time that I was not actively providing some input to the Firefox program.

This only happens when clicking a link from an email in Thunderbird most of the time it is a news platform. I have to copy the link and open a new tab in Firefox to have it work.

I have a subscription to Global Cycling Network, to which I login using my Google account at https://plus.globalcyclingnetwork.com/login. The login web page has options to login using Google, Facebook, or Apple, but in a normal Firefox window, the buttons for using these logins never appear - I just get a whirling circle where the buttons should appear, and the page never completes loading. If I open the GCN login web page in a private FF window, the buttons appear and I can login without any problem. If I use Firefox Settings to clear all cookies and cached web data, then close and restart Firefox, I still can't login from a normal FF window.

I tried the Edge browser (OS is Windows 11) and login there works without problem

Any suggestions on a fix to get it working on Firefox? FF is presently version 119.0.1.

Recently have been unable to access the USPS Website from any of my Firefox Browsers. Firefox displays the following Message:

You do not have permission to access this page If you have found this page in error, please contact support Reference:10593116689666961403465577003670526342620034968299102359

Hello. I have 2 Other Bookmarks Folders. One near the top under the Bookmarks Toolbar & one at the bottom. They seem to have the same folders & bookmarks. I'd like to delete one, but I'm apprehensive about that because I think I would end up deleting both of them.

Any suggestions. Why do I have two? Thanks In Advance, Carol

anytime I type www into the URL window firefox autopopulates youtube.com even though I have turned off auto suggestion. It shows up before the bookmarked links !

it always automatically checks the "Search suggestions ahead of address bar results" and will not let me uncheck it.

I just dont want it to suggest anything and am okay typing the complete URL. How can I fix this issue? I am including snapshot of what the autosuggestion, settings and version info in the attached doc

When I upload the photos using Mozilla they becomes less saturated. The browser changes the color of the photos itself because when you download the photo back to a computer and compare it with original one in the photo viewer, the difference is noticeable. After some research, I found advice to use the gfx.color_management.mode set to 0, it helped, but the photos after upload looks over-saturated, but only in Mozilla. In other words, the photos after upload looks over-saturated in Mozilla (the way the browser displays them) but the browser does not change the color of the photo itself as it was before, because there are no any difference if compare with originals after download to a pc. I attached an example, but did changes in the third photo on purpose just for reference, because as I said earlier, the colors of this photo are displayed normally in all other programs except Mozzila, I just wanted to show how it looks in Mozzila.

Hi, so here's the issue I have: Lets say you have 20 tabs open where the "tab scroller" becomes active and tab#17 has a video, if you enter & exit fullscreen on that tab then tabs #18-20 will slide to the right and go out of sight. This is quite annoying as I'd prefer all tabs on the right to be visible until I manually scroll to the left.

I tried googling for about:config or userChrome.css solutions but couldn't find anything, does anyone have any ideas on how to change this? Thanks.

Lately, far too many websites I try to open, simply won't! Sometimes it's via links from my home page, sometimes it's links within various websites, like a newspaper, or social media, just whatever, no rhyme nor reason, nor consistency. Even when I manually input the url, nothing happens, the browser just sits there, nothing happens. I've restarted, I've refreshed websites, clicked on "open in new tab/window", nothing gets it to work.

I'm a Reddit user and until today I used to login just fine. Now I get the error message "Incorrect username or password" when I try to login in Mozilla Firefox (version 119.0.1 (64-bit)). If I use Google Chrome or Microsoft Edge I log in with no problem.

Firefox bookmarks exported from old Windows PC to html file. File transferred to new Windows PC and imported into Firefox. 'Bookmarks Imported Successfully' message seen. However no bookmarks visible in Firefox bookmark menu. Suggestions please?

I was having trouble with Firefox freezing and needed to close it with Task Manager and reopen it whenever this happened. On one of these restarts, only a few of my windows opened up with the new session. All of the other open windows vanished. They're not in my history or my recently closed windows at all. There are three specific windows of the lost windows that had data I was actively using and don't want to lose. The URLs would be enough. I was also using the other windows, but I can re-find that information easily enough.

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

YouTube won't start playing in Firefox. No add-ons enabled. The page is fully loaded, but clicking on Play makes nothing.

The fix is to disable "User recommended performance settings" and then disable "User hardware acceleration when available".

The problem is that hardware acceleration is enabled by default. In Edge or Chrome hardware acceleration is also enabled but it won't break YouTube.
