I'm having huge memory problems with Firefox. In about:performance I can see that the extensions process takes up way too much memory. When I start Firefox it usually shows a memory usage of around 180MB. However, at some point the memory usage of the extensions process starts to increase and it doesn't stop increasing until my RAM is full and then it increases even further. It increases until I restart Firefox or until it uses so much RAM that my computer runs incredibly slow.

Below you can see a screenshot of the Task Manager showing how much RAM is available on my computer and a screenshot of the about:performance page showing the memory usage of the Extensions process. The RAM available on my laptop is 10GB (the default configuration was 4GB of soldered RAM plus 4GB of exchangeable RAM. I have upgraded from 4+4GB to 4+8GB but 2GB of the soldered RAM on this laptop are used as GPU memory so the remaining RAM is 10GB). The about:performance screenshot shows a memory usage of 13GB for the extensions process which is possible because Windows automatically pages RAM on the SSD when I'm running low on available physical memory. This enables programs to actually use more memory than the available physical RAM but of course programs become incredibly slow when the RAM is full and huge parts of memory have to be paged on the SSD.

My actual question: How can I find the cause of these memory problems?

What I've tried so far

- I have created a memory report on about:memory. The result is at the bottom of this post. - I have watched the about:performance page and tried to find out what action triggers the memory usage of the extensions process to increase. At the start of the browsing session the memory usage is only at around 180MB. It stays like that for a while. At some point it starts to steadily increase by many GBs. But I couldn't find the cause. I don't know what triggers the extensions process to increase memory usage. - I could simply disable extensions and see if the problem gets solved. But I want to know which exact extension causes this problem. It is very difficult to find out which one it is because I have many extensions and I don't know what causes the memory usage to increase. So I would have to disable extensions one by one and wait for an indefinite amount of time and check whether memory usage stays low. But I don't know how long I have to wait until the memory usage would increase because I couldn't identify what triggers it to increase.

Rather than just using trial and error I would like to find a way to use debugging tools to exactly determine what causes the problem.

This (https://pastebin.com/U3QXTAt9) is the memory report from about:memory. This contains the whole extension (pid 18332) section (copy & pasted by selecting the text on the about:memory page). I have left out the rest because I don't know if it contains private data. Please note: this is not taken from the same browsing session as the screenshot that shows a memory usage of 13GB. Why? Because programs run very slow when memory is low and large parts of memory are being paged. The debug tools usually require a lot of RAM and CPU performance so it's very difficult to use the debug tools when the memory is already full and programs are already running slow. This memory report shows a very high memory usage of the extensions process. In this case it's "only" 3.5GB but it was taken in an early stage of the increasing memory usage. As shown in the screenshot below, memory usage can go even higher than the available physical RAM on my computer. The memory report doesn't clearly show which extension is responsible for the high memory usage. In the memory report, I can only see a high memory usage for the items gc-buffers and gc-heap which leads me to think that the memory problem has something to do with the garbage collector. However, I cannot see which extension is responsible for this. No item in this list with a description that identifies a specific extension has a high memory usage. This is only an excerpt from the memory report (only the extension section). I went through the whole memory report with Ctrl + F "moz-extension" and looked for items with a high memory usage but I didn't find a single item with high memory usage that belongs to a specific extension.

'Every time' I'm on a webpage I get that question if I want to have this page translated into German.

PLEASE - How can I deactive this !!!

wie kann ich das Beta Fenster übersetzen ausschalten / deaktivieren?

Good afternoon,

I am trying to install UrbanVPN free on my firefox browser but it tells me that I can't have the extension.

Can you please help.

Kind regards.

Read Aloud charged me $25.00 on 5/31/25, but I did Not subscribe to this feature. And when I open my Firefox browser to I see where I can add this feature, but have not as I do not need it.

I called the phone number listed on my American Express charge, but it states "this number is not in service." Also, I visited the website, and it looks like a phishing shell that first asks for my credit card number to 'look-up' the charge. No way!!

I'm disputing this charge with the AmEx, but you may want to be aware of this issue. My office does not allow us to use Firefox, and now I see why.

Before I uninstall Firefox, I'm removing all credit card history from the background.

More and more websites are moving to a subpath (doing `example.com/en/webpage-here` instead of `en.example.com/webpage-here`).

If the open site in container can be modded (manually, not via UI) to open a subpath (say `example.com/en/`) in a container, that would be very helpful.

I don't know if this is possible or how to do this (given it is possible).

I watched a video about blocking youtube ads on firefox. It said add adguard, ublock origin, and adblocker for youtube. When I tried to add adblocker for youtube, a screen came up saying it had to verify I was human. I clicked the box, but the screen kept coming back. Please let me know how I can add adblock for youtube. Or is there another way to block ads on youtube? Thanks, Frank

I have been having a lot of trouble using the LastPass extension. I used to get a message saying "This is taking too long - Do you want to use Offline Data. Now I just get a message say an error occurred. I would then go to the LastPass web page to log in. I get the same message.

In desperation I downloaded Google Chrome and don't have a problem there, but I don't like using Google Chrome. I have been a long standing user of Firefox so do not want to change.

Hi all,

I'm an English speaker in Germany, and I'm trying to add amazon.de as a search shortcut, using the official steps (right click on address bar, choose 'add Amazon').

However, I'm getting the following error: Firefox could not download the search plugin from: https://d2lo25i6d3q8zm.cloudfront.net/browser-plugins/AmazonSearchSuggestionsOSD.Firefox.xml

I've seen similar calls for help that seem to stretch back years, but alas they appear to have had slightly different symptoms/solutions that don't seem to apply to my situation.

Cheers.

I have never used this setting. When a addon update is released, I want to see release notes. I want to see what has been improved, fixed,if and how the options have been altered, etc.

Several weeks ago this happened, and I found seven items in the "recent updates" section.

I just happened to go to the went to the addons manager today, and realized it had been selected again, with another addon in recent updates.

Does this have something to do with a browser update automatically making the selection?

Even if it is selected, why is there not at least some type of notification that updates are being made?

The settings have the option for notifying if a browser update is available? Why not have the same for addons?

I have been setting up Passkeys to log in to the websites which allow them. But I have noticed on Paypal, they do not allow me to use passkey when using firefox, it only seems to allow chrome

Is there an issue with firefox which deems it not suitable for passkeys?

I noticed that sopmeone asked this question this time last year and it was advised that firefox is now able to create and store passkeys Paypal still dont seem to allow it?

In your extensions, Nord VPN shows in grey and not in blue, when I click on the logo, all I get is an advert picture. How can I download Nord VPN and reinstall the app on my PC? I can't add an image as the advert page disappears when I try to take a screenshot.
