Why is Firefox freezing up with bookmarks problems and then opening old tabs upon restart. No bookmarks are imported. Firefox is ruined as of 12/1/23.

Instructions are too complex for average user. Help is no help at all. Why no tech support for Firefox browser issues?

Starting on 12/1/23 Firefox browser on Windows PC is Not Responding while loading up bookmarks toolbar. Switching to "Never Show" is only way to load the browser. Trying to open or manage bookmarks freezes up the FF browser again.

I have recentlly built a new pc. I have updated windows, graphcs drivewrs and checked that the ram is good. I have submitedn the crash log: bp-c292b4b1-dbec-41f5-a25f-5823f0231202

Managing Firefox bookmarks has become impossible as of 12/1/23. Browser freezes up and then task manager shows multiple instances of FF open.

No help is available anywhere. Community blames the user, mocks the poster, blames PC configuration when nothing was changed. Only offers impossible to understand instructions. Help topics don't help at all.

Why is Firefox freezing and crashing as of 12/1/23?

Where can one get help?

In the last few weeks I've had problems uploading videos to sites like Meta's Business Suite using Firefox. So I did a little investigation today with a video on Microsoft Edge and Chrome browsers and had no problems uploading using the simple command "Ctrl + O" but it failed on Firefox browser. See pics attached. Whatever improvement you've recently made has totally screwed up my workflow.

Got a problem on two separate computers: Mozilla Crash Reporter keeps popping up when Firefox is not even running. I'm guessing that my antivirus avast is interfering with the update service. I'm I right or wrong? Otherwise, does anyone know how to interpret this? This is the report:

Resize or enlarge is not working well after browser stay opened more than few minutes, only close and re-open of the browser work: https://drive.google.com/file/d/1_8PtMgoyxvHFcXyddJXkr8z4rfmSLhkM/view?usp=sharing About my browser: https://i.imgur.com/Uwy68UQ.png My linux is: Ubuntu 22.04 firefox installed by Snap.

Need to clear all previous activity [history, cache, etc.]. I create websites. Do NOT save history. Option turned off. When I bring up a changed website, I see the previous version or the one before that half the time. Rebooting PC does not clear it. Am tired of playing browser roulette, trying to find a browser which will A. Show the latest version. [which is being displayed on other people's devices] B. Perform the desired action as designed by the product creator [which works on other servers and devices, and even sometimes on my device using another browser] I am not skilled at seeing physically thru other people's eyes, only imaginatively. My partner is 200 miles away in another state. We don't always see the same, even when the display is identical. Am starting to create 2 versions of sites, a .org and a .com and explaining to people WHY. I think the "don't save" does not work. It merely turns off creating an index of the viewed material and leaves the viewed material in cache. And re-displays the initial data eveytime, no matter how many updates. Thank you.

What am I supposed to do about this new problem?

"XUL Runner This profile was last used with a newer version of this application. Please create a new profile." I did create a new profile. I have like 4 different profiles now from every time I've had to reinstall Firefox because it keeps crashing and freezing.

I have been getting this error message for over a week now, PR_END_OF_FILE_ERROR. My internet is fine and I have restarted my computer a few time since the problem started. I have added some sites to the Exceptions list but even then they don't work properly. I have tried refreshing Firefox and changed the profile and they both didn't fix the problem. I am sadly not knowledgeable enough to make sense of the Web Developer Tools. The attached image is what my YouTube page looks like after add the site to the Exceptions list.

Foxnews.com causes Firefox 102.0.1 to freeze when scrolling pages with lots of images. Closing and restarting FF does not help. The freeze reoccurs. What does help for awhile is to delete the file places.sqlite. After that FF runs for a few hours until the problem happens again. Is there a setting or other fix for this issue?

AdBlockPlus and uBlock Origin are both installed, but are disabled on www.foxnews.com.

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

Immediately on update to 96.0 this afternoon, multiple sites failed to load - Google(Maps, News etc), Yahoo, Flightradar24 etc - others partially loaded - then sat there blank. Explanation of errors is NOT clear -

Is it possible to revert to previous version? Everything seems to work fine when using EDGE!

Hello,

I've just downloaded firefox, making the switch from chrome. Doing so I've migrated a couple of tabs and extensions I had. Totally it was 50 tabs, with 6 extensions, I've downgraded now with the switch and it's only 37 tabs and 2 extensions, even so firefox is using more ram than google by a large amount. With 50 tabs open, chrome was using 1.5gigabytes of memory. With the same 37 tabs and extensions, firefox is currently using 6 gigabytes of memory.

The tabs used are from reputable sources, so firefox shouldn't be breaking on these websites. The extensions I am using at the moment on firefox is, Ublock origin, Dark Reader.

As far as reputation goes, firefox should be using less Ram than chrome. Is there a setting I should know about to lower such performance issues? Firefox acceleration is ON.

Thank you for any answers.

The latest example is the button to sign into LinkedIn. It is not working in Firefox, but it does in other browsers. I have other examples just from today. I have used firefox as default for many years. I assume this is a security thing, but these are basic links. I have no add-ons or other complications. Most times, I do not even realize there is a problem, but when I feel something is wrong, I try another browser and it works. Thank you.

I had the same problem like the link below when I use firefox.

https://www.reddit.com/r/firefox/comments/tjxh7s/videos_freeze_when_window_isnt_in_focus/

So, did what the instruction says and it solved the problem regarding discord.

But, since I changed that setting, firefox doesn't remember my google login or dark skin settings of other websites (it was always automatically logged in when I use YouTube. Not like it remembers the password).

How can I solve it? I resetted firefox multiple times.

Hello all. Since the update to Version 113.0 I have been getting an error in my Event Viewer which is Event 2 Firefox Default Browser Agent . I am now on Version 113.0.1 and still get this error. Firefox is my default browser. Below is an image of what I see in my Event Viewer and also the full view of the event itself. I seem to not be having any problems with the browser but I was wondering if anyone could shed some light on why this is happening or forward to the Devs.

Respectfully, Don

Hello,

I've spent several hours today trying to fix FireFox slow start up on my system. After start up (about 2 full minutes), everything works normally. The hardware is an ASUS A88xm-A MB, A10-6800K processor, 16G DDR3, runs OS and programs off an SSD. I worked through all the slow startup suggestions, ran memtest (0 Errors, 1 Pass), disabled all add ons, (even the OpenH264 video codec (I use the onboard HDMI, no graphics card)), turned off hardware acceleration, etc. When starting in troubleshoot mode, less than 30 seconds, (acceptable), but I really don't know where to begin with the "More Troubleshooting Information" when I look at the table generated by it. There have been no other problems to date with the system, and the long start-up time began with 20.04 Ubuntu (about a minute), then got worse when I upgraded to 22.04 to try to solve THAT problem. Currently running FF 104.0, and the update page says wait for a distro update if that is how it was installed. I believe 104.0 is the latest Linux 64b version though. All updates to the system are done as soon as I'm notified of them. there have been none since the upgrade a few days ago.

Any suggestions? Gotta get some sleep now... TIA, Dave
