Firefox RAM usage on M1 Mac has dramatically increased. Unfortunately, b/c the memory usage is in firefox parent process, I can't simply terminate a process corresponding to a "tab", meaning I have no choice but to restart Firefox (closing & reopening all tabs) every hour or so of usage.

This is a new issue from a long-time firefox user (on multiple operating systems). It happened after I upgraded the Mac to "Monterey", which may or may not be coincidence.

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...

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

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!

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 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

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'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.

So, on Windows 10 I noticed that when I click the History tab I see Show All History and when I click that the only option I get is Today..very odd.

On my Windows 7 Home Premium when I do the same steps I have access to "Today", "Yesterday", "Last 7 days" and various recent months.

This is what I'm accustomed to and was hoping to get input on why I only get Today option on my Windows 10 computer.

Looking forward to your reply...

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

When deleting Firefox' history I can choose to clear "active logins" and/or "cookies". But "cookies" are mostly used to store information about "active logins". So there seems to be some overlap. I'm interested in the technical difference between the two. I suspect "active logins" is clearing only session cookies, while "cookie" is clearing also/only non-session cookies? But I haven't been able to find reliable documentation on these details. Could someone help me out?

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?

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.

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.)
