Diễn đàn hỗ trợ Firefox

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!

Certain emojis are no longer showing up for me while using Firefox. They will show up as as little boxes with numbers and letters instead of the actual emoji art. This doesn't happen with all of them, only certain ones. I have attached a few screenshots for reference.

Also, I have attempted to fix this issue by changing my default fonts, disabling addons, etc. Nothing seems to work. When I use Chrome, I have no issues seeing these emojis.

Thanks!

I made a few changes to about:config. How can i save the about:config settings for a new Firefox installation? My bet is this is possible either with distribution-policies.json or with a HTML. I used Kali Linux, this operating system comes with a pre-configured Firefox installation. For example it uses a permanent darkmode with duckduckgo even while cookies are denied. It also comes with customs about:config settings like disabled telemetry.

Those are all the setting i changed and i would like to find out a permanent way to import them to Firefox, right after installaing the Browser. It's time consuming changing each setting manually after each install...

toolkit.telemetry.enabled false browser.urlbar.placeholderName DuckDuckGo app.update.enabled false geo.enable false extensions.pocket.enabled false pref.privacy.disable_button.view_passwords false network.protocol-handler.external.mailto false datareporting.policy.dataSubmissionEnabled false datareporting.healthreport.uploadEnabled false browser.newtabpage.activity-stream.feeds.telemetry false browser.newtabpage.activity-stream.telemetry false browser.newtabpage.activity-stream.telemetry.structuredIngestion.endpoint leer browser.newtabpage.activity-stream.telemetry.ut.events false browser.ping-centre.telemetry false toolkit.telemetry.archive.enabled false toolkit.telemetry.bhrPing.enabled false toolkit.telemetry.firstShutdownPing.enabled false toolkit.telemetry.hybridContent.enabled false toolkit.telemetry.newProfilePing.enabled false toolkit.telemetry.reportingpolicy.firstRun false toolkit.telemetry.server leer toolkit.telemetry.server_owner leer toolkit.telemetry.shutdownPingSender.enabled false toolkit.telemetry.shutdownPingSender.enabledFirstSession false toolkit.telemetry.updatePing.enabled false toolkit.telemetry.unified false toolkit.telemetry.prompted false toolkit.telemetry.rejected true toolkit.telemetry.pioneer-new-studies-available false experiments.activeExperiment false experiments.enabled false experiments.supported false network.allow-experiments false media.peerconnection.enabled false (WebRTC leaks)

If you know any more settings that shuld be disabled, please let me know!

I had to do a computer reset on my laptop back to factory settings, everything ok now except one annoying issue I cannot seem to resolve. Some websites I was using perfectly ok in Firefox before now show as tiny text/font size and or generally looks wrong (in firefox) and nothing I do seems to resolve the issue, for example I'm viewing some websites at 130% but some text on the page is still too small. I can view the same sites in chrome with no issues at all at normal 100% level, The best example I could give I can't paste here for obvious reasons, my hargreaves lansdown pension values text is all squashed together so individual text that shows on one line on chrome (correctly) shows as condensed into 2 lines in firefox, the text is big but the values beside it are not for example, any increase in the zoom level doesnt really resolve this issue, yes the text gets bigger but I shouldnt have to read it at 150% zoom !!! but 100% is waaay too small, and the values size is not in sync withe the text beside it. I count myself as fairly savvy technically, I've tried all sorts including clearing cache and cookies and checking settings etc in firefox but this one has me stumped, some sites work ok but it looks like Firefox may be struggling to cope with some sort of display extension that some sites are using to display some parts of their page Any ideas please ? Thanks

Hello, i am having problems resolving or finding some answers on my newly updated mozilla since i turned on the (automatic update). Now im on Version 93.0 and it is the latest, also observed that my screenshot was gone lately. The screenshot tool was very helpful to me. What should i do now? Should i wait for another update? Thank you

https://www.puticollege.com/welcome was working fine with version 82 of firefox. When I upgrade to 93.0, this page has a big solid blue box where more html should be shown after a page. No error in console log, not sure what's going on.

It still works fine in latest chrome.

Please help.

I've got a new computer I am setting up from scratch, and though I have set FF to sync settings, I'm still having to customize a lot. My bookmarks toolbar is crowded again with icons and I'd like those to go away. I don't mind other icons staying around on the tabs--that does help me navigate faster. I had this set up before, but lost the setting when I refreshed Firefox.

I cannot set my preferences because the preferences menu will not display when I select Command, from the pulldown menu under Firefox in the top left banner. I am stuck with whatever this is. I cannot set my search engine. I cannot set my popup preference. I cannot set any preference. I use Mac BigSur 11.5.2. I can't share data. I am having trouble streaming my favorite radio station because I cannot reset my popup preference for the station. Nor can I use my search engine: DuckDuckGo without typing it into the Start search box because I cannot set my search engine preference. I cannot set other preferences because it seems I don't have any options since I can't get the preference menu.

Firefox 93.0 64bit Linux Mint 1.0

When I close (X) the window, my session is not restored. I have checked all the settings and verified that they are set correctly. Then, I found that when I tried to quit the program via File menu, it says that I have two windows and three tabs open, yet I only have on window/one tab open. I can not find this other window... What does this mean? Have tried refreshing the app, safe mode, and disabling the extensions that I use.

Thanks!

On the rumble website, videos are slow to load (10-17 sec) when I'm logged in. If I log out, videos will load instantaneously. At first i though this was a rumble.com issue but then tested with latest version of chrome MS Edge the issue doesn't happen.

I would like a warning before multiple tabs are closed but in settings I don't have this option :

"In the Tabs section of the General panel, check the box next to Confirm before closing multiple tabs to enable the warnings, and uncheck it to disable them".

FF is offering me two versions of my e-mail when I login to a website where I have specifically told it to 'never' remember a password. The little black selection dropdown shows both myUserName@myMailserver.com myUserName@myMailserver.co When I click to login page of 'website.com'. It does not offer this for all websites that use e-mail address as login.

I have checked and the website in question shows up in 'never save' exceptions to my 'ask to save usernames and passwords'.

So I have no saved passwords to remove for that site--when I look up 'website.com', I get nothing.

2 questions: why does FF continue to offer a login name for that site?

FF 93.04 beta (will be updated in a few minutes to next version) MacOS 11.6 Big Sur and where can I find and zap 'myUserName@myMailserver.co' without losing all of my other logins & passwords that I do allow FF to store for me?

Hello, I have recently noticed that firefox starts playing files where it used to give a prompt on whether to sav or open file. I know I can right click- save link as, but I would like it get the prompt instead, if possible.

Hi, Opened firefox today on my desktop pc and the open tabs at the top of FF just stroll to the right/end of my tabs as soon as i put the mouse over them to select one.

try use left arrow or scroll wheel to go to the left and just immediately mouse over to click a particular tab and before can immediately scrolls back to the right/end.

also have noticed when at the right of my open tabs mouse over any tab and whereas before would get the pop up showing the title of the page now just flashs the title up for a fraction of a second not even enought time to read it.

plus now have tried to select from the drop down box in this ask your question dialog box but when click on down arrow to select the appropiate section just flases up the options for a fraction of a section giving no time to select one. Have found only way to select is to use the arrow keys on my keyboard

thanks ian

OS: Ubuntu 21.04 x86_64 CPU: AMD Ryzen 7 3700X (16) @ 3.600GHz GPU: NVIDIA GeForce RTX 2060 SUPER

When I have two windows running and one of them is playing either audio or video on its active tab, the other window runs at a very low FPS. This is noticeable when scrolling, as CPU usage appears to increase dramatically while monitored.

The problem does not appear when running firefox in safe mode, but I cannot determine what might be causing the problem when firefox runs normally: the problem persists when I disable all extensions, as well as when I use the browser's default appearance as opposed to the theme of my choice. As far as I can tell, I have not modified any about:config settings either, although some cursory searching online suggests webrender may be a cause.

I was using Firefox, had one window open...browser was moving slowly so closed it. When I went to reopen-even in safe mode-it loads windows I had open and then suddenly crashes...I cannot refresh it as I have a lot of custom settings and bookmarks...this is the crash report I keep getting, can anyone help me please?

Firefox just updated itself to 93.0 and now suddenly I have a big black border around the searchbar when it is focused. The userchrome "#searchbar { border: none !important; }" gets rid of the white border when the searchbar is not focused, but (just a stab in the dark) the userchrome "#searchbar[focused="true"] { border: none !important; }" does nothing when it is focused. How can I get rid of it? (It can be seen in the right-hand part of the attached image.)

I was checking out these tweaks

Firefox Quantum About:Config Tricks You Need to Learn

I'm curious about "Lower Memory Usage When Minimized". Is there a downside to this? Why wouldn't this be a default setting?

Details: This tweak is mainly for Windows users. When you minimize Firefox, it will send Firefox to your virtual memory and free up your physical memory for other programs to use. Firefox will reduce its physical memory usage, when minimized, to approximately 10MB (give or take some), and when you maximize Firefox, it will take back the memory that it needs.

The preference name does not exist and needs to be created.

Right-click on the background and select “New -> Boolean.”

Enter the name when prompted: config.trim_on_minimize.

Enter the value: True.
