I use Firefox on Ubuntu 22.04, and my system has 16GB RAM. I have been facing this problem of frequent crashes for the past few months. By crash, I mean not Firefox alone, but the entire system. I use several apps and run several processes that require great compute resources, often simultaneously. I have narrowed the cause of frequent system crashes to Firefox alone; the system rarely crashes when I use other resource-heavy apps. Due to this, I have to restart my system several times a day.

Before this problem arose, I would use multiple tabs (including YouTube, often 10+, close to 20) and multiple windows (2+). Such usage very rarely caused crashes, which is why it is surprising that Firefox now causes the entire system to simply hang sometimes with as low as 3-4 tabs.

I have disabled Hardware Acceleration, refreshed Firefox, even tried disabling WebGL. I also tested it after removing all add-ons, but it still didn't help (I use only 2 add-ons: a simple wide-spectrum ad-blocker and an EPUB reader). Even in troubleshoot mode, Firefox will cause my system to heat up, although it takes some more effort to crash in this case. I use one of the standard themes, so it could not have been the problem.

Many people report Firefox crashes, but in my case, Firefox causes my entire system to crash. How do I fix this issue? Thank you in advance.

Why has this started up again? Pdf files are automatically downloading to my computer when all I want to do is look at the file. So many files that now need to be trashed after looking at them. This problem has happened in the past, but was resolved, only now I am finding it happen again. I do not want to have files saved unless I want to save them, not Firefox deciding that any file I open should be saved. I have Windows 11 & Firefox Version 113.0.1. Is there a way to revert to an older version of Firefox?

Hi,

I'm trying to configure equipment on my local network. Some of the equipment does NOT support https. Firefox continuously changes the address http://192.168.xxx.xxx to https://192.168.xxx.xxx, and the connection fails!

I have tried the various options in HTTP Only Mode, including entering Exceptions. I have also temporarily changed network.trr.mode from 5 to 1 (and 0), but nothing is working!

What can I do?

Thanking you Pedro

Hello,

I am trying to understand if there is a way to customize the tab rearranging behaviour.

In particular, the thing I find very unpractical is that, after a tab is closed, the others do rearrange, but after the mouse goes out of the tab bar. This is particularly annoying when I have to close multiple tabs, since thanks to this behaviour, the tabs which I close after the first one are always the unintended ones.

The solution would be to let the tab rearrangement happen instantly after the closure of the tab. In my opinion even without animations, I do not really care about that.

If you have any suggestions let me know.

Thanks in advance!

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.

I've been searching for a way to hide the tab bar and reclaim that space. Some sources on the web set to change some settings in about:config and edit userChrome.css, but this did not work. This question links to an add-on to do it, but the link is broken:

This again!

This was resolved about a year ago; now the problem is back, as of updating to Firefox 113.0.1 this evening.

Initially post-update the close tab button was in a weird, random place on the tab bar. I have adjusted the margins to put the button back where it's supposed to be!

I changed :

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 2px !important;
}

to:

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 35px !important;
}

to move the button back onto the left. That may seem like a drastic change but that's the lowest value I could find which produced the result I want.

However, it's not quite the result I want! As of updating to 113.0.1, the tab title itself now disappears altogether on hover.

I have tried to correct this in CSS using the .tab-text and .tab-label attributes, but without any luck so far.

Can anybody help me with this, before I'm forced to downgrade to Firefox 112?

Better yet... how about we just make this an option in Settings, as it should be?!

Hi Firefox won't stick to the taskbar after a reboot of the pc. And it is also showing that it likes that it is install even after a totally clean re-installation of it.

When I scroll down to look at recent posts on Facebook groups I follow all but the top one has suddenly lost its date/time – I just get a blank where the details would usually be and have to hover over to reveal the details. The silly thing is that this only happens when I sign in and it doesn’t happen when I use chrome – although I prefer using Firefox, not least because the bookmarks sidebar is better. I have tried getting rid of all extensions and running in troubleshoot mode but without success. Any help/advice would be appreciated (as long as it is not about football!)

I don't know if breakage is the correct topic. I keep Ring.com open to the dashboard in a pinned tab. A few days ago, I had viewed and cleared videos as usual and later returned to view new activity. The site requires logging in every 30 days and so seeing that I needed to do so was not a surprise. What was a surprise was that the login buttons were grayed out. I closed the tab, cleared the Ring cookies and cache and tried again. No luck. I wondered if there was some other setting that I didn't know about and decided to open a private window and try it there. To my surprise, it works. I'm stumped. I'll attach the raw data from the private window as a .txt file. Darn. I can only attach an image. Well, I have it available and can copy and paste it into a subsequent post if you think it would help

Hello Community,

I have always found the "Save Image As..." menu command when right-clicking with the mouse in order to save an image. Recently the website where I download these images from has implemented an automatic zoom feature that changed this standard menu (now appearing with commands such as "Save Page As...", "Save Page to Pocket", "Select All", etc...). I cannot access any command that directly relates to the underlying image and so I am not able to save it. The website developers assured me that with their own browser (not Firefox, I presume) the "Save Image As..." option is still available, suggesting me to install a different one. I believe the reason of this change in behaviour is because the mouse does not find a direct link to the image any more (as if there was a layer in between running a script to enlarge the image).

My question: is there any other way to access the menu option I need? Why should other browsers be able to "see through" the image and have the standard menu?

Thank you for any suggestion.

Since the task limit option seems to have been obliterated? I believe the many more "programs" and the events they create for windows to handle is causing all sorts of virtual memory problems. Changing win10 advanced system settings from performance for programs to background services seems to have restored Firefox performance in my case, see: 10 advanced system settings win10 advanced system settings performance programs vs background services Is there an about:config option that would allow one to achieve the same "programs" limiting option as before? This laptop has 16 gig of memory and I used to successfully have even better Firefox performance with windows virtual memory turned off, but eventually I would get crashes. I can understand why Firefox was modified in a way to better localize the source of crashes, but in my case it has degraded performance. Thanks Mozilla for a great product I have valued for years!!!!

Since yesterday on Facebook I can't see the time a post was written like I always had and like it happensa for example on Chrome, does this is happening to others?

It seems like no matter what I do, I can't get Firefox to download files from Google Drive. It loads for a moment, then it says "The page isn’t redirecting properly". I have confirmed that it's only Firefox because I can download files from Google Drive with Google Chrome. I have disabled Enhanced Tracking Protection, selecting the Standard Enhanced Tracking Protection Setting, and even refreshing Firefox. Though, I noticed that it only works on incognito mode for whatever reason.

When FF (113.0.1) is maximized clicking on the first (left hand) pinned tab does not open the tab. Hovering over the tab doesn't change the background color of the tab.

If I restore down the window, hovering over the tab changes the background color of the tab from light grey to a slightly darker grey and clicking the tab opens it.
