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!

Since three updates ago there are white bars on three sides of my Firefox window whenever I disable the title bar. (The bars should be visible if you open the first picture I've attached over a coloured background. The second picture shows the bars disappearing when the title bar is switched on.)

This problem persists in Safe Mode and even after a fresh installation of Firefox, so I am confident that my add-ons and themes are not the issue. The bars also show up when using the Firefox default theme, so a custom theme is not the problem either.

I have also tried, to no avail: Updating my graphics driver, changing my screen scaling, cleaning the registry. And of course simply restarting my computer.

I am at a loss as to what the issue is or how I can fix it.

My minimize/maximize buttons have suddenly gone missing. I found other answers on this site that say Tablet Mode is the culprit; indeed, the density settings within Firefox are telling me Tablet Mode on.

However, tablet mode was officially removed in Windows 11. It's not in the settings, it's not in the Control Panel, and registry edits don't seem to work either. So what's going on here? A regression? How do I get my minimize and maximize buttons back?

Nightly 95 on Windows 11 - Minimize & Maximize Buttons Are Missing

I have recently clean installed Windows 11 on my computer. I have noticed with the current Nightly 95 install that the minimize & maximize buttons are completely gone, only the close button is there. Even when I click on the area where the 2 missing buttons are nothing happens. When I double click the same area, the area behaves the same way as the rest of the top bar, it either makes the current window become a smaller window or a full window.

I have also installed Firefox 93 and 94 Beta 6, they both behave as normal with the minimize and maximize buttons visible and usable, just like any other program or Firefox version ever on Windows. Also, before I clean installed Windows 11, I used Nightly 95 on Windows 10 within the last day or so and I don't recall ever having this behavior happen there either.

Is this behavior on Nightly 95 on Windows 11 intentional or an error? I know Firefox has and is going through a massive GUI update and other user facing changes with Proton, but wasn't sure if this had anything to do with the trouble I am experiencing. I also understand that Nightly may have a lot of changes and features that are unique to it. I honestly just wasn't sure about this issue.

Thank you in advance for any and all help!

Firefox will not open saying it can't find the profile. There is a profile in the Application Support folder and old ones on the desktop. I followed the directions to access the profile manager through Terminal, but it didn't work. This Firefox Application is one I restored from Time Machine. I got into this problem when I tried to update Firefox. My MacOS system does not meet the requirements to install the latest Firefox. Apparently, my former Firefox got uninstalled in the effort to install the latest version.

Firefox display issues on Windows 10 21H1

I'm confused by this issue as Firefox worked fine until recently but an older version doesn't fix the problem. At first I only had issues with LibreOffice and Firefox. LO would only open in safe mode, Firefox opened but did not working correctly. The fix for LO was to disable skia so I suspect that is the cause of the Firefox issues, but it could also be a driver issue. Weird thing, Google Chrome also uses skia and although I had an issue with Chrome suddenly not loading, an uninstall/reinstall fixed it. I am aware skia is a Google project so it may be that Chrome and Firefox use different versions of skia.

Issues: Firefox opens and I have my extensions etc across the top but the main window is blank. No websites display. Switching tabs doesn't work. If I open a "More troubleshooting information" tab for example, I can only access/view that tab by closing the first tab. A few menu options work (help menu - Troubleshoot Mode and More troubleshooting information both work fine) but Settings doesn't work. I tried Firefox in safe mode but it makes no difference. I tried refreshing Firefox but it makes no difference. I tried clearing the startup cache but it makes no difference.

This is on a dual boot with Windows 10 and Ubuntu Studio 21.04. I also have Firefox v93.0 (64-bit) installed on the Linux partition and it works fine.

I'm using Firefox Portable. For some reason, in text fields, firefox will randomly "paste" (for lack of a better term) the localhost into a text field and act like it's pressed enter. It can occur when I'm changing tabs, typing, and occasionally when I'm doing nothing at all.

Is there any way to stop this? I've updated the software and tried reinstalling. I don't have any extensions or anything added to the base install. It happens randomly, but more and more frequently. These are new Windows 10 computers (mostly Panasonic FZ-55s, some Dell Toughbook models), and I can't find anything on them that would be causing this issue.

Any help would be greatly appreciated.

Ever since I started using Firefox which was months ago, I've been getting this "Hmm. We're having trouble finding that site" page multiple times a day when opening links to various websites. Refreshing the page makes it load correctly. I've tried troubleshooting this in the past but didn't spend too much effort, but enough is enough. Things I have tried:

  • Disabling all extensions
  • Disabling hardware acceleration
  • I am using the default theme so there's nothing to disable there
  • Clearing the cache
  • Checking my internet connection (I'm connected and everything else works)
  • Flushing my DNS
  • Resetting Windows, which included reinstalling Firefox (I did this to fix something else, but still)
  • Disabling IPv6 and DNS prefetching
  • I am not using a Proxy

I feel like I've tried everything. What else can I do?

Hello!

I have been having an issue with Firefox not starting and/or running and loading any web pages.

Mine was on V 88 when it suddenly wouldn’t load any web pages – seemed frozen, but would occasionally connect to one. My internet connection is good and Chrome is just fine.

After many tries – closed FF, reopened, restarted laptop – it just wouldn’t load anything. So, I finally clicked the update to v 93 – which it haltingly did and finally seemed to open after several tries. But now, it again won’t load anything. Everything is just a blank page. I can see bookmarks and history, but can’t access any of them – nor can I access anything in the settings link.

I tried the refresh directions, and still the same thing. See image for all that loads.

I do have the "old" profile from V88 - would I be able to use that to possibly roll back to that version and then address the issue if it still persists?

Thanks for the help and suggestions!

Also, why does it clear my clipboard? I Ctrl-C'd a url before closing it just now, and after it crashed and a restarted it, Ctrl-V was empty.
