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!

I used to run Firefox 88.0.1 (64 bit) on a Windows 7 PC. With lots of help from this forum I wrote a userchrome.css file to make several changes to the appearance.

On a new Windows 10 machine I installed the same version of Firefox (since I don't care for the latest one). I added my old profle to the new installation and selected it as the default.

Unfortunately, when I opened the program I was prompted to create a new profile; there didn't seem to be any way around this. So I let it happen and tried simply copying my old chrome folder into it - I thought at least I could make the visual changes even if I couldn't import my bookmarks and so on.

But this didn't work either: when I run the program, none of the expected changes are there.

Presumably I've done something wrong, but what, exactly? I'd be grateful for any thoughts. Ideally, I'd like to use the whole of the old Win7 profile but if that's not possible at least changing the appearance would be pleasant.

Many thanks.

In the bookmarks sidebar (Win 10 PC), when using "search bookmarks" and after typing an entry to locate, I thought that there used to be a "button" (x) in the far right of the search field that would clear any entry and return the view of bookmarks in the sidebar to that which was displayed prior to the search.

Has something changed or was I just imagining this.

If my rampant imagination is at work, please consider this a feature request

Thanks

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.

Firefox Beta and earlier have a minus sign on upper right to minimize to taskbar. That is missing in Nightly. Firefox Beta and earlier have a square box on upper right to go from maximized screen to normal screen.Now, double clicking on the top bar does the latter, but that box is missing in NIghtly.

As a result, Nightly has become unusable. I early await the fix.

For some reason images are not loading in Outlook.com when I use Firefox. Images load fine when using Chrome or Edge, but Firefox is my preferred browser. Is anyone having a similar issue. I know there was recently an issue with the site itself but it seems MS resolved it but perhaps whatever they did only fixed the issue for chromium engines?

Firefox Version 93 64-bit

  • I have used troubleshoot mode and it works temporarily so I thought it was an extension and turned them all off but the issue persists. I reset Firefox but it did not correct the issue.
  • I have disabled the tracking protection and no change
  • I went in to Outlook.com settings and toggled the 'Use outlook services to load images' and no change.
  • Emails are marked as safe senders.

I think I hit all the major tips I have read online so I'm hoping I'm overlooking something. Any thoughts?

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!

I use Google Calendar on my PC, my Android phone, and even my Kindle Fire. Problem appears only on my pc when using Google Calendar in Firefox (when I use Chrome, everything is fine). In two months (so far, Oct 2021 and January 2022) NO EVENTS SHOW UP. If I enter an event in either of these months, it will show in Chrome, my android, and Kindle. BUT those 2 months are completely blank when using calendar in Firefox. Clearing cache, disabling Adblock for the calendar page(s), reloading has not helped. I would really appreciate any possible solutions/help. Thank you

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.

Hi! so I installed Kubuntu 20.10 after using it 'directly from the cd' for some time. since, all data would be lost every time i restart, i would keep a copy of a '.mozilla' file i would find in the system. Everytime i start the OS, i would first create a folder and copy paste it, so firefox would start right where i left it off. this worked, until i decided to make Kubuntu permanent. at first things were going good, but after sometime, my OS would stop recognizing my headphones and audio port completely. at first i blamed it on my OS and went about doing somethings here and there to adjust by. but looking back, i had installed some DRM to play some video on the net. so in a desperate fix, i replaced the current .mozilla file with a backup i had. the thing worked like a charm and my audio was fixed and everything was going ok, except for the occasional fixes so that my OS would channel the audio to the right output. that is, until the problem rise again! this time, i hadn't installed anything like i did previously, so i replaced the .mozilla file again and it worked! but i can't keep doing this and i had also faced the same problem in my windows, resulting my change in OS in the first place (I think its the same issue, because whatever i did didn't fix it and windows is more sophisticated that i wouldn't know). I don't know if this much info is too much or too less or that if i should post this here or in any other forums, but i would really appreciate it if i got a solution! Thankyou!
