Firefox Community Forum

I've been using Firefox for many years without a problem and have always liked it, but I've recently starting encountering a problem where Firefox consistently crashes after closing. After I close Firefox, the Windows Task Manager shows it still in memory. After a couple of minutes, the Mozilla Crash Reporter screen pops up informing me that Firefox had a problem and crashed, with an option to restart Firefox or Quit. I tried refreshing Firefox, which was a challenge because of the problem of hanging in memory after closing, but it did not resolve the problem. I also tried uninstalling it, then deleting the Mozilla folders and clearing out any references to Firefox in the Windows registry, and reinstalling it. I haven't installed any extensions yet; but sadly, I continue to encounter the problem. Any ideas about how to resolve the problem?

I should mention that I had bought a new SSD for my computer and migrated everything over from the old SSD to the new one. The problem with Firefox began after the migration. Everything else that was installed there works without a problem. I would be surprised if this is related to the issue considering I've reinstall Firefox.

On a late model Dell laptop, there are no domains listed under Exceptions-Cookies and Site Data. When I key in a domain (whether using www., http, https, or just the domain name by itself.) and click on Allow, that website is not added. It's the same as if browser security is stuck on Remove All Websites. With the same Privacy and Security settings on my desktop, I do not have this problem, so it appears not to be a matter of altering particular settings. Short of removing and reloading Firefox on the laptop, which might work but not teach anybody anything, are there suggestions?

Firefox was working well on HTTP websites until a few days ago, but now HTTPS-Only Mode seems to be permanent. Despite changing settings to 'Don’t enable HTTPS-Only Mode', when HTTP sites are selected I get the same message as for 'HTTPS-Only Mode'. Also, if I select 'Enable HTTPS-Only Mode in all windows' and add exceptions, I get the same result.

With the latest version of Firefox the menu, etc. have a font size that is TOO SMALL. There are many Mozilla posts about this problem.

My wife cannot read them. I can barely read them. If this is not fixed soon, we will switch to another browser.

Can the Firefox code writers fix this?

The behavior began with fifteen to twenty crash messages appearing. After which the browser would stop responding and be unable to reach out to the internet.

Network connectivity was confirmed as I was able to access my VPN and corporate teams.

I submitted as many crash reports as I could. Eventually the crash reporter ceased to function. The message is:

Firefox had a problem and crashed. Unfortunately, the crash reporter is unable to submit a report for this crash.

Details: expected value at line 1 column 1

Only a full reboot of the machine restored functionality but only temporarily. It returns after being put into sleep mode.

Running firefox in safe mode does not restore functionality. The behavior persists.

I am fully up to date according to firefox.

I am running a Lenovo Thinkpad Windows 11.

There used to be an extension called "IE Tab". It allowed you to right click on the link, and open the site in a tab, using Internet Explorer, for sites that didn't work properly in Firefox. I was wondering if anybody knows of any similar extension that would do the same for Edge? I can't open Twitter (X) using Firefox anymore, but I can open it using Edge. I don't like Edge (obviously), but I have no choice. Thanks in advance!!!

Hello!

I recently got a new PC, and every time I open up Firefox it instantly closes. I have tried downloading it on the Microsoft Store, it seems to work fine for 5 minutes and then it happens again.

I have been using firefox for more than 4 years now. But from about a year, i m facing the issue with the Sudden High CPU usage in Windows task manager.

The task manager has 2 different firefox processes. One being actual instance i am running. and the 2nd being the automatically opened in background.

i have figured out whenever i have active internet connection and my system is on charging the 2nd task automatically starts in background and uses upto 80% of cpu usage. Ending the 2nd task form task manager doesn't affect anything. only the cpu usage drops. Also Closing my firefox instance does nothing to that 2nd task.

I have tried lot of solutions i found on community. Nothing seems to help. problem still persist. I even posted comments on ongoing threads. but no reply from anywhere.

this is the last time i m trying. if i get a solution its good. otherwise i am going to shift to edge. I have no other choice.

Screenshots from multiple dates are attached.

Starting, I believe, with 12/20/2023 build of FF Nightly, the "Page Info" window has a bizarre alternating highlight on the media tab, and full highlight on the Permissions tab, but no highlight on the Security tab. Other FF windows, like the download/history box, have no issue. I could change Windows theme to dark to invert the all backgrounds to black, and the text to white, but that's just hiding the issue. Nothing in add-ons was changed, and none of them would cause this.

I'm really confused about how profiles and sync work together for what I assume is a pretty common use case, especially now will all the WFH. I have two devices:

1. Personal laptop 2. Work laptop

I'd like to keep my bookmarks, history, addons etc separate, but be able to access my work environment when working from home on my personal laptop. I've read a lot about profiles and sync and multi-account container but I'm still confused as to how I achieve what I'm trying to do.

Having multiple profiles on one device is straightforward. But AFAIK if I attach two profiles to the same sync account, and try to sync both between two devices, it will only sync one of the profiles (and then merge everything if I try to sync the other). And if I have two separate sync accounts (work and personal), each with a single profile, I can't switch between them without also merging everything. How does one achieve this then?

I have the browser.urlbar.trimURLs switched to TRUE but still as you can see in the screenshot it shows the complete URL with the protocols. I do not want this, I want it to hide it and only show the main link like youtube.com instead of https://youtube.com

The subject website pge.com has blocked Firefox apparently because new function that they have instituted features that Firefox cannot support. The subject website states it does not support Firefox. Is this refusal to support on the subject website a known problem? I have searched the Firefox Help without results. Is this even considered a problem? I appreciate Firefox and would like to see it be a supported browser on the subject website.

Hi

Well Firefox did it again. I had tabs on the bottom where I wanted them and they broke this again in the update I just got.

Any idea how to move them back down to the bottom? This is the userchrome.css coding I was using that worked fine before the update

Have been unable to view readers comments for a number of weeks and can figure out how to fix. it is not all the time, like last night were available but not this morning. All other browsers there is no issue including DuckDuckGo. Am using Ublock Origin, but have been using for years with no issue, even when turn off result the same.

Everytime I go to play games on my laptop I close Firefox for the extra resources and when I'm done I open it right back up, I have done this for YEARS but this time it didn't restore my session. I thought it would be as easy as the last time where I'd go click the Restore Session button but it isn't there so I spend two hours looking for solutions and found nothing. I don't know how this happened nor do I understand how this could happen in the first place, my Firefox hasn't crashed in months and I had already closed and re-opened it several time today.

In reference to my previous post ( https://support.mozilla.org/en-US/questions/1382198?page=1 ) I have noticed that the "jumping while scrolling" in the Facebook News feed has returned after a couple of months of proper behavior. Ver. 108.0.2 It's not as bad as it was but it seems to be getting worse.

Is the circus back in town?

Am I going to have to move back to Chrome again ?? >:-(

Hi Firefox We work in a government institution and we use Firefox because it is a unique, fast and safe program. We thank you for your efforts to develop the browser But we encountered a problem with the new update while printing the PDF files. It was showing us the option to print in portrait or landscape format, and when you updated version 14, this option no longer appeared. Where we deleted the new program, installed the older version, and stopped the update We trust you to solve the problem in the next update, and we ask you to give the matter importance

Every other search I do a Redirect Notice pops up. How do I get rid of this. Have used MS Edge and this browser does not have the problem, I am reluctant to transfer to Edge but will if I can't resolve this issue.
