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.

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.

Hello,

I have a problem retrieving my favorites/bookmarks. I changed computers (all of them, even the hard drives).

I would like to recover my favorites/bookmarks but cannot do so because I am asked to look for them in folders that I no longer have, because they are on the old computer.

Does Firefox not save any information about my favorites/bookmarks? Have I lost them all? Do I have to redo my whole life?

Sincerely, Shinsengumy

Firefox seems to be hanging up my computer every once and awhile. Why I think FF, if I am able to kill it with task manager- all is well. Prior to that system is pretrty much locked up, sometimes can't even get task manager running. Also, about twice a week I get a message from FF about oops your Foxnews tab has stopped., please send report. I haven't sent report, just do a reload.

I have run 3 virus checkers, chkdsk and sfc /scannow and all are okay no virus, disk or system files missing.

Thinking of switching browsers for awhile?? Then seems there is a place in profile that has passwords, but I forgot where. Maybe I could download a completely new copy of firefox and keep my profile?? Then again maybe my profile is messed up.

Any suggestions the best way to get a completely new copy of FF??

On Windows 10 current release and now FF 119.0. Down to using Flagfox, Malwarebytes Browser Guard, tab reloader, undo close tab, web threat shield (webroot). Was for years using Noscripts, but stopped it for the last few weeks. Actually I stopped Malwarebytes Browser Guard, web threat shield and noscripts and still got hung up. That only left Flagfox, undo close tab and tab reload running as addons.

Version 120 (PC) continuously crashes and asks me to refresh and nothing happens (including after rebooting) so I had no choice to uninstall. I normally trust your updates but I'm really regretting this one. Can you help me not switch over to chrome? Maybe you're already aware of this bug and will have it fixed soon.

I use a VPN connection to access my workplace. This means that all my DNS queries MUST go through the company's VPN tunnel.

Firefox is deliberately blocking my work. The DNS over HTTPS "feature" does not work over this VPN connection.

In Firefox, there was previously the following setting: Preferences > General > Network Settings > Enable DNS over HTTPS

I REALLY NEED to have this setting restored right now.

We have 2 desktop computers, both on the same wifi internet wireless network. On 1 we can ad the Ublock Origin extension no problem. But except for only 2 times, the other computer says installation aborted because add-on appears to be corrupt. Like I said, we have gotten it to load twice but both times it disappeared and now it won’t load. I’m not sure how it can be a connectivity issue, since they both access the internet from the same source. Is it that the problem system has Window 11 and the other 10? Why would it install twice and then disappear? Note that as a test I have uninstalled Ublock and then reinstalled it no problem on the Windows 10 machine. Does anyone know how to fix this? Thanks.

Dear Sir/Madam,

I need help with Mozilla Firefox 119.0.1 (64-bit) version which is almost not working internally without Internet link. When I try to open local internal site Mozilla Firefox waits to open https://www.bootstrapcdn.com/ Internet location which is unavailable because we are using the browser in isolated network and it is waiting for this site for more than 15 minutes before it opens the local site.

This is not the way we are expecting the browser to work so the question is can we disable this requests in Mozilla Firefox that we were not aware of and that are not asked from out side?

Thank you!

Why is this so difficult? I keep getting the attachment. How do I stop it? I NEVER WANT FIREFOX TO TELL ME THERE IS AN UPDATE. I will check and update when I'm ready. How do I stop this?

Hi, for months now, Mozilla, keeps crashing, or asking me to install new updates very frequently. Today it told me I have an old version (I do not) and that I need to create a new profile. I love your privacy policy but am about to give up your product. I have an IT dep and they were not able to help either. Best of luck fixing these bugs

See the attached .gif in the past could I use a "mailto:" link without problems, I used this extension: https://addons.mozilla.org/de/firefox/addon/outlook-com-mailto/ But even, when I deactivate it, does it NOT work. As you can see in the gif, the website opens and the mail does not load. usually it should create a new empty email ready to send. I tested it with gmail (because I have a gmail accunt through google) and that worked.

So there is some problem with outlook, this does happen on every page, tested also with disabled adblocker (ublock).

I'm watching a YouTube video and taking notes simultaneously. It used to work fine, but today, possibly after update 119.0(64-bit), it's not functioning properly. I couldn't resume my video with <space> after switching back from my note using <ALT>+<TAB>.

Any solution for this? Or should I consider downgrading my FF?

When switched to mobile hot spot from wifi [and viceversa] Firefox can't load websites but other browsers can. I am facing this issue recently like from a month or so. Before that all working fine. I have already tried the troubleshooting steps from here https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can, Still no luck! Edition Windows 11 Home Single Language Version 22H2 OS build 22621.2506

Note:Whenever i switch to mobile hot spot i have to restart laptop to make Firefox work.

Is there any permanent solution for this problem?

I'm using last release Firefox in a fresh install of Debian 12 with KDE. Trying to personalize colors and get a coherent style, I've installed Firefox Color and it worked fine, except for a few GUI elements.

I solved the scrollbars part with this answer:

https://support.mozilla.org/en-US/questions/1419353

Is there a similar setting for the menus? I mean in Firefox's menu bar or the ones popping over the page. The dropdown of the burguer menu and the bookmarks toolbar do get styled (I will include images showing the difference).

Thank you in advance and to zeroknight for sharing the bit about scrollbars!

I'm having an issue that has been going on for some time now and it finally has me at wits end. My Account sync keeps disconnecting where I have to go through the sign in process again and again. I have searched multiple times for this issue and have seen that others have suffered from the same issue with no clear solution to the problem. I have now tried with several Firefox desktop versions including my preferred browser being Firefox Unbranded, and every single one disconnects me several times daily.

Does anyone have a solution to this issue?

Since the last update (earlier this week) firefox uses large amounts of memory. It shows in the windows task manager 20 and more instances of firefox being open and one of them using 85%-90% of the available memory. I looked up help articles regarding this issue and one of them mentioned to "Delete content-prefs.sqlite file". When I do that it will help for a short period of time but then the issue is happening again. I'm using Windows 11 64 bit.

I'd appreciate some advice on how to deal with this.
