Firefox needs a limit on memory usage. I was developing a tiny web page on Linux (PopOS) and accidentally created an endless loop in Javascript that ate memory (by growing an array). My entire OS became inoperable and had to be hard-rebooted. I was surprised this could happen due to Javascript (a sandboxed browser language), running in a web page (a sandboxed app) running in a Firefox browser that is supposed to protect users from the world wild web. One errant line of legal Javascript in HTML should not equate to a denial-of-service attack.

A sensible approach would be similar to the nice warning given when a script takes too much CPU, offering the user the choice to continue or stop the script when a tab exceeds some reasonable size: a fixed MB size, or say 10% of real RAM memory.

Ideally there should also be some hard limit calculated by Firefox according to the machine's available memory and Firefox's reasonable percentage of it. For example, maybe limit Firefox (all tabs combined) to 50% or maybe 75% of real memory, so that the O/S has a reasonable chance to remain operational so that a bad tab can be closed. Otherwise, Firefox could cause the O/S to lock up, resulting in data loss if there are tabs or other apps outside of Firefox that have unsaved changes.

Thanks for your consideration!

Hi,

I have scoured the web and can't seem to find a solution to this. Either firefox doesn't support this feature or I haven't looked enough.

How can you identify the pid of a tab in firefox? There isn't a tab in the task manager that shows this, like with chrome, opera, and edge.

I'd appreciate any help.

Thanks

Hello there !!!

Today I had serious damage to my Mozilla Firefox. When I started up Firefox I realized that I lost all my opened tabs on all my (three) opened windows, although I had checked the box "Restore previous sessions" in the settings section.

I opened "settings" and I saw this box unchecked !!!!!

The unfortunate event of this failure is that I restarted Firefox and even worse I restarted the PC.

Now I wonder, after all these, if there is a way to restore all my lost TABs that, I believe, there are hidden somewhere...

I had an issue where when I tried to open firefox I received an error that said ""A copy of Firefox is already open. Only one copy of Firefox can be open at a time". After looking at some other support articles I came across this article that appeared to fix the issue after entering a command in terminal https://support.mozilla.org/bm/questions/1254772, and I guess I deleted the wrong version because after being able to reopen my browser I had none of my saved bookmarks, extensions, history, or any other account info.

Is there any way I can recover my lost browser info or am I just completely SOL?

On bankofamerica.com, when I log in, it asks for acknowledgment and once I give it, a terms and timeout timer window is supposed to pop up with a 'continue' button further down. I only get the top 1/4" or maybe 1 line of the window and can not get past this point. It works fine on other major browsers. Any ideas on why?

Since the upgrade to version 93 many times Firefox freezes (blue circle moving on screen) and the complete screen is filled with the browser in such a way that the Windows tray is not visible. This is particularly being done when several pages are open in the browser simultaneously. Sometime after this freeze the browser closes itself without any notice. This is rather annoying when I am in the middle of a work.

Here are the details of my OS: https://pastebin.mozilla.org/DkNG2o5X

Please find attached a picture what can be seen when the above freeze happens.

I'm trying to find a way to change where Firefox 93 stores my temporary internet files away from C Drive to a different drive to reduce lag. I found an article on how to do it using the about:config utility, but I can't do what that article describes — right-clicking in the about:config browser does not give me the option to create a new string; there is no "new" option.

How do I change this in Firefox 93?

Hello,

Right now, my browser is formatted such that the tabbar is on top. This works fine but there is a tiny gap of a few pixels from the top of my screen to the top of the tab. This results in not being able to move my mouse to the top of the screen and selecting tabs. Is there some way to remove it so that I can select tabs even with my mouse at the top limit of my screen?

Also, when I have two or more tabs opened at the same time, the whole info bar (where the tab bar and nav toolbar sit) shifts downwards. For instance, when I have one tab open, the whole info bar is X height. But when I open a new tab, it widens to an X+ height. If I close this new tab, it will shrink back to X height. How can I fix this?

Thank you for you're help

Upon upgrading from FF 16 to 17, I can still drag the icon that's to the left of the url to the desktop (or even to the XP Quick Launch Bar, Folder Shortcuts, etc.) to create an internet shortcut to the current page. However, with 17 this method produces a shortcut that shows a generic Windows icon instead of a Firefox-page icon. Even though a generic Windows icon normally denotes "no program associated," these still open with FF when double-clicked. But it doesn't look right. (BTW, all the shortcuts created by this method in FF 16 or lower retained the FF-page icon with the upgrade to 17.)

Any ideas why this changed and how to fix it so it looks the same as before?

Pending resolution of this (and another issue) I went back to FF 16, and it works normally again. However, the shortcuts that were created while I had 17 still show the generic Windows icon.

fixed in Firefox 21 - locking this old thread
