Firefox Support Forum

Hi,

I am encountering an issue where Firefox throws an "Uncaught out of memory" error in the console, despite my system having ample RAM available. Here are the details of the problem:

• Error Message in Console: Uncaught out of memory
• Memory Usage Observed: Using about:processes, I noticed that Firefox's maximum memory usage caps at around 7GB.
• System Specifications: The machine running Firefox has 128GB of RAM, so there should be plenty of memory available.
• Firefox Version: 126.0a1

Given the significant amount of RAM available on my machine, it seems unusual that Firefox would hit a memory limit at just 7GB. I suspect there might be a bug or a misconfiguration causing this issue.

Can you please assist in diagnosing and resolving this problem? Are there any settings or configurations I should adjust, or is this a known issue with the current version of Firefox?

Thank you for your help.

Firefox will not allow my to post comments on Yahoo. I have no issues with Chrome or Safari. I get the following error message: Your comment failed to publish. Retry

Tried to reset settings. Does not work. Went to about:config, than tab.mo / print.tab_modal.enabled set to false. Did this method before and it worked. Now this method does not work trying to get print preview back. Firefox is my web browser. I am in windows 8.1. Seems like Firefox did some updates again and now I can not get print preview back! WHY DOES NOT FIREFOX LEAVE WILL ENOUGH ALONE WHEN THEY HAVE SOMETHING GOOD? Bring back the old classic print preview button back and leave it. Now how can I get the old print preview button back???? Need help!! Thanks philm

I can't get Firefox to store bookmarks on my Mac since I installed Monterey 12.0.1. I managed to find some instructions on your trouble shooting page but they do NOT work. Hate to give you guys up, but unless y'all can help me fix this, I'll be moving on.

Hello, I've followed Firefox's invitation to install and update the browser on my Mac. Unfortunately the new version is not compatible with OS 10 El Capitan, my operating system, so now I can't use Firefox at all. How I do get the old version back?

Thank you, Lars

Hello,

We are using Firefox on macOS to access web services that require Certificate Based Authentication. Our certificates are stored on YubiKeys PIV slots.

If we plug the token, open Firefox and access the website, it works just fine. The Certificate picker is shown and the OS ask for the PIV PIN to validate the access.

However, if we do the request when the token isn't plugged, Firefox does not ask for it, the website deny the authentication and the context is kept in cache. Requesting again the web site with the token added in between does not restart the certificate lookup and we are forced to close Firefox or move to a private window to make it works.

What is the proper way to avoid this issue? Is it a known bug? Is there a way to configure Firefox to always show the certificate picker even if no certificate are found and then reload the list of certificate based on connections events?

Thanks

Unfortunately, I downloaded “SaveFrom.net Helper” without reviewing it.

Since downloading it I have been receiving a alerts from “McAfee WebAdvisor” about “dangerous pages blocked”.

I was able to remove the “SaveFrom.net Helper” add on in Firefox, but am unable to remove the “Savefrom.net Helper” bookmark tab which has high jacked my normal Firefox Bookmarks.

I can no longer easily see my Firefox Bookmarks and have to keep opening the Firefox Application Menu, then select Bookmarks, then select Manage Bookmarks in order to see my bookmarks.

Can you please advise how I can safely remove the “SaveFrom.net Helper” bookmark tab which has high jacked my Firefox Bookmarks.

and not only that, when I click on sign in - it shows me a work email address that I rarely use - not my Firefox account / main email. I have to click NEXT then change email address from the drop down menu. I followed the setting attached. but it's still does it. I close Google tab, then go back and im signed out again! It's extremely annoying. How on earth can I fix this?

My tech info: Macbook Air Mac OS 12.2.1

Help continuously mentions something about clicking a "shield" to the left of the address bar, yet my up to date Firefox shows no "shield" anywhere i can find. Has an update obviated the need for it, and if so, do we have updated help files to reflect the new control for security, vpn and cookie usage?

When using Google Meet, you are given the option to share your screen — either the entire screen, or a specific Firefox window.

I've noticed, however, that no matter what Firefox window is used, if you access an extension that creates a pop-up dialog, such as the Container selection button from Conex, the uBlock origin settings popup for each webpage, or a password manager pop-up such as Bitwarden, those popups will appear on the shared window, even if you decide to do this from another Firefox window altogether.

This is a major security concern for me, as I've had circumstances where the password entry window for Bitwarden will appear on any window, even if I open the extension pop-up from a window not being shared to Google Meet. I'm not sure where to submit this issue, so I'm starting from the Mozilla support page and going from there. Would appreciate anyone's help on getting this issue resolved. Thank you.

Crash? My Windows 10 tablet pro pop-up keyboard stops working for Hulu & YouTube so far. That's the main ones I'm on for that device. It won't keep popping up for me. Is there a way to be sure that Firefox messages always get to my main email? I want to be sure to get a notification, once someone can reply.

I have the same problem as this person: https://support.mozilla.org/en-US/questions/1011006

but I have a windows 10 and the solution does not show up in the Taskbar settings. Is there an updated version for this? Here is the OPs original question.

"When I open a new Firefox window, it stacks it on top of all the others in the task bar at the bottom. I would like them to be BESIDE each other. It used to do that. Now I have to hover over the ONLY Firefox item on the bottom task bar and read the list to find the one I want to go to. This is a waste of time and tedious.

How can I change this?"
