I have an autofill issue with certain websites. When I go to that website, the search feature automatically fills in with my password. Obviously, I don't want my password publicly showing up on the site. I have deleted history, cookies, cache, etc...but for whatever reason when I go to this specific website my password will automatically be showing up in the search feature. How do I get rid of this?

Thank you to anyone that helps.

While using Debian 12 on two workstations running version 136 the "update available" would appear on the screen and remain on the screen with no option to update or cancel.

Because this happened on 2 Debian 12 workstations, i would like to know if this is a known problem as I updated 139.01 an the issue continues.

You will noticed in the screen capture update available has no options other than "learn more"

When I right-click an image, the context menu opens with an option to set the image as a desktop background. For almost all web images, this action makes no sense whatsoever, and for the others, I personally never want to use it.

How can I drop this action from the image context menu?

I have searched settings for context, background, and image, and I have searched about:config for desktop, background, context, etc.

Superuser has an answer making use of about:config `legacyUserProfileCustomizations`, which I would prefer to evade given its 'legacy' nature.

I expected an about:config flag but have not found one.

I have a Mac and downloaded the Firefox application. I opened it in Applications, and it wouldn't open noting: "Your Firefox profile cannot be loaded. It may be missing or inaccessible." I followed the directions by going into my terminal with the following: /Applications/Firefox.app/Contents/MacOS/firefox -P

But I am getting the same message about the Firefox profile. Firefox will not open, any other suggestions??

Hey, I'm trying to port a game save file to and the game but when i access the save file it shows a Firefox logo on the left and when i try to port the file, it never works even though i follow all the instructions. Can anyone tell me how to change the symbol back to the normal white blank one please as i think that that is making it not work.

Many thanks :)

Why does Firefox Desktop now completely crash every time I press the Ctrl and cursor keys whilst navigating through text?!!! Very frustrating and I've had to abandon using your app completely. Please fix and redeploy your app as a matter of extreme urgency!!! thanks

What can you do about it?

inbox.lv has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

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.

I have used Firefox for ages now and love it. I have noticed in the last few months that some functions on some web sites are not able to be accessed. Such as submit, place an order, and the like. I have to use another browser. Is there any reason for this as I really don't like to use any other browser other than Firefox but it seems to be that I have to. Is there some way that I can get around this?
