Technical issues After update. I have two computers both of which some problems since the latest Update in February. The microphone won't work on certain apps. One of my extensions are operating as expected and Firefox is not closing all the way or so it's reported. When I go to open up again a new session, it says it's already open but not responding. I have the option close it and then starts right up.

Hi,

I’ve recently noticed that after a Firefox update, the browser has become very slow and unresponsive whenever I open multiple tabs, around 5–10. Before this update, I could open many tabs without any noticeable lag.

Now, new tabs take a long time to load, scrolling within open tabs feels choppy, and sometimes Firefox freezes for a few seconds before responding again.

I’ve already tried restarting Firefox, disabling extensions one by one, and clearing the cache, but none of these steps have improved the performance. I’m using Windows 10 and the latest version of Firefox.

Could anyone suggest what settings or troubleshooting steps I can try to fix this slowdown?

Hi All,

I would like to remove the first item from the Tab Context Menu, which is "Add Tab to New Group", and simply have "Reload Tab" as the first menu item.

I was using this code, which worked in FF 145, until the latest update (FF 147)...

#context_openANewTab,
#context_moveTabToNewGroup,
#context_moveTabToGroup,
#context_ungroupTab + menuseparator {
   display: none !important;
}

However, now there is an extra separator line at the top of the menu (see attached images).

This code also removes the top menu item, but still leaves the separator line on top:

#tabContextMenu #context_moveTabToNewGroup {
  display: none !important;
}

Is there a way to remove the first menu item without adding the separator line?

Thanks!

I used to be able to have all sorts of tabs open for an entire month. Now, I can't keep them open even for a day. It seems to be a problem selective to Youtube (other tabs like Yahoo Mail still work), leaving my Alienware 15R4 laptop fans running really loudly for a few days now, since updates ran (not sure if that's related), and leaving me having to shut down and reboot the browser, daily, instead of once or twice a month. Is there anyone working on getting us back the old Youtube, or replacing Youtube with something like what it used to be? I am running adblock plus and uBlock Origin, should probably turn them off to see if they're related to the problem, huh? I'd hate to start having to use a different browser.

Windows 10 Home V 22H2 Alienware 15R4 Firefox 147.0.3

I am using Windows 11 on a Dell laptop. I have the latest version of Firefox installed. I have used Firefox as my default browser on this machine and O/S for the last year with no problems. I can use Firefox to get to other websites without issue, using either a 5G cellular connection or a WiFi connection direct from the Dell laptop. I DO NOT use password vaults or any kind of automated password entry, and I do not have any bio-metric access functions activated on the laptop; I enter usernames and passwords manually, as needed. I have accessed my Outlook Hotmail account using Firefox without problem up until about 4 weeks ago. Now, I can enter my username successfully, but when I then enter my password I get a rejection screen response from Microsoft (clicking on it, I then get a "help" screen about what to do after getting a 404 message). After navigating through a maze of screens from Microsoft I will get an opportunity to verify my identity by using my cell phone and entering a 6-digit code (essentially a form of "2 factor" identification) and then I will get access to Outlook on the Firefox browser. I should mention here, that I don't use 2 factor ID on my email or with Outlook, and after entering my password, I would have been connected to my email directly. I do NOT have this issue when I try logging in to Outlook using Chrome or Edge on the same machine. I have: rebooted my machine, reinstalled the latest version of Firefox, cleared cache, used Firefox in Safe Mode, cleared cookies and browser history, turned off tracking protection, cleared URLs from tracking protection exceptions, and tried various combinations of all of the above. I also ran "scannow" and "DISM" functions to make sure Windows is not corrupted. Nothing has fixed the problem, and, Microsoft Support claims that since the other browsers work, the problem must originate with Firefox (surprise, surprise! ...). Any assistance in what steps to take to get Outlook to accept passwords that are sent through Firefox would be greatly appreciated!

I have at least one question on the support forum which has never been answered. So I went to Bugzilla, and discovered dozens of YouTube issues under the Open/Unconfirmed status.

I can reproduce my problems. I'm sure others can reproduce their problems. Nothing is done. NOT EVEN admitting there is a problem.

If I can't use YouTube on Firefox (I can't), then why am I using FF? It is one of the biggest sites on all of the internet. But FF apparently doesn't care if it doesn't work.

What. Is. Going. On?

(See the attached image... the big blank space is where the video should display)

Whenever I try to full screen a Youtube video a large solid white bar will appear on the bottom of my screen. It doesn't block the actual video or even the controls but it seems to push the entire video upwards. It only does this on firefox and only on youtube. It seems to be a solid empty space as I can't click on it and right clicking just gives me video playing options. I've tried restarting my computer and firefox a few times and that didn't work. It does however change size and with the browser zoom and color mode respectively. please help.

When Firefox updated to 147.0.3, it shredded Quick Dial and I am using the latest version.. Less than half of my tabs still exist, and many of the "everyday" tabs - banking, utilities, online purchasing, etc, - are simply gone. Unless there is a solution, and I have contacted the developer with no success, I will no longer be a Firefox user. Beyond this issue, Firefox has been increasing difficult to use for purchases (big examples, Rock Auto, PayPal) and have had to switch browsers too many times to complete purchases DESPITE making exceptions for these websites in Settings. This situation is the proverbial "last straw". Solution or I'm out. Screenshot attached would have originally shown A FULL PAGE OF TABS.

My firefox broswer is starting super slow since the last update. I am on a windows 10 lap top running McAfee anti virus software.

In my task manager there are multiple firefox icons running. See the attached screen shots.

I copied one of the crash report into the note section below.

If any one know show to correct this slow start up pleas let me know.

Thank you Dale

This problem has been covered in this forum before. However, the various solutions have not worked for me because it seems my backup previous.jsonlz4 was corrupted. I did exit Firefox normally, but I am not sure because I have been using multiple different browsers in recent months.

This is what happened this morning: my Firefox on Mac OSX was closed normally, and I rebooted the MacBook. Afterwards, I could not restore old tabs because "Recently Closed Tabs" and "Recently Closed Windows" are greyed out.

I tried copying recovery.jsonlz4 from the last folder and putting it into the main folder as sessionstore.jsonlz4, then reopening Firefox. Still have no restored tabs. Here was the surprise, which I do not know how to interpret.

I just checked some files and found this error message in sessionrestore-logs folder:

1770888233416 SessionStore ERROR SessionSaver write() rejected with error: Error: SessionFile is closed(resource:///modules/sessionstore/SessionFile.sys.mjs:424:29) JS Stack trace: write@SessionFile.sys.mjs:424:29 write@SessionFile.sys.mjs:47:32 _writeState@SessionSaver.sys.mjs:375:29 _saveState@SessionSaver.sys.mjs:308:17 _saveStateAsync@SessionSaver.sys.mjs:354:10 saveStateAsyncWhenIdle@SessionSaver.sys.mjs:194:14 requestIdleCallback/<@Timer.sys.mjs:180:15 observe@AsyncShutdown.sys.mjs:570:17

Every time I open more than a couple of tabs, a Firefox pop-up asks if I'm overwhelmed; I'm not. How can I make it stop? (I have already unticked Recommend features in Settings and set browser.newtabpage.activity-stream.asrouter.userprefs.cfr.features to False.) Equally annoying is the constant 'Summarise page' feature reminder. I have certainly Got It! by now.

Starting about a week or two ago, I noticed the text of Firefox is grainy. But when the cursor moved, it would get grainy in a different way. So, some letters which were previously unreadable became readable, but other letters became unreadable.

Going to the same web pages with other browsers renders the page readable. So, the problem seems to be Firefox specific.

Even while typing this, portions of the characters on my screen blink in and out.

If there is no solution, I will have to utilize some other browser.

Thank you,

I want youtube to go back to the list of websites on the url drop down menu. I'm annoyed that Heroforge replaced it after only two visits to the website and I don't know why it even did that.

Recent (Windows?) update signed me out of Firefox. Logged in again, but bookmarks aren't showing up. Bookmarks are marked for sync-ing, and I did try sync-ing twice. Maybe I have to sign back in on the original device?

I have configured Firefox to use a proxy, and I stored the credentials in the password manager. However, every time I open Firefox, it asks me to enter the credentials again.

How can I store the proxy credentials persistently?

I have been running version 147.0.2 on Windows 10 Pro. I manually downloaded the version 147.0.3 updater and ran it without any apparent problem. However, when doing the required restart, the update process did not complete. Multiple restarts and cold boots have not remedied this. When I start Firefox using my desktop icon, version 147.0.2 is started.

My "Programs and Features" window shows both versions are installed. When trying to uninstall either version, in either order, I receive a message saying that the system should be restarted to complete the update process. As stated, this does not work.

Following a restart, the Performance Monitor does not show any recognizable "ghost" processes that would need to be stopped.

Inspection of the System event log showed the following Warning:

 *  Name resolution for the name push.services.mozilla.com timed out after none of the configured DNS servers responded.

There may be other warnings / errors that are pertinent to this situation, but that was the only one that mentioned "mozilla" or "firefox" by name.
