The Firefox Browser crashed three four times last week. Mozzila Support team after study, gave a comment that RAM capacity is Low( 4 GB in my case , laptop). Does it sound OK? Why it does not happen with Chrome or Microsoft One edge Browser? I asked this to Google Gemini. The answer is as given below: Yes, the Mozilla Support team’s explanation sounds entirely accurate.A capacity of 4 GB RAM is extremely low for a modern laptop running an operating system like Windows 10 or 11 alongside modern web applications. The operating system itself routinely consumes 2 GB to 2.5 GB of RAM just to keep your computer running, leaving very little leftover memory for heavy multitasking. Both Google Chrome and Microsoft Edge use built-in "efficiency modes" and aggressive tab-sleeping algorithms. When your computer begins running out of RAM, Chrome and Edge will silently put inactive tabs to "sleep" to free up memory before the browser crashes. [1] (https://www.superchargebrowser.com/library/firefox-vs-chrome-ram-usage-2026/) Good Solutions to Fix the Crashes- 1. Software Adjustments (Free & Immediate)If you want to keep using Firefox smoothly on 4 GB of RAM, you need to minimize its memory footprint:Reduce Firefox's Content Process Limit: By default, Firefox uses multiple processes for performance. You can lower this to restrict its memory use:Type about:config in the Firefox address bar and press Enter.Accept the warning.Search for dom.ipc.processCount.Double-click it and change the value to 1 or 2. This forces Firefox to use fewer system resources. [1] (https://en.wikipedia.org/wiki/Firefox)Enable Memory Minimization: If the browser starts slowing down, type about:memory in the address bar and click the Minimize memory usage button under the Free memory section.Use a Tab Suspender Extension: Install a lightweight add-on like Auto Tab Discard from the Firefox Add-ons store. It mimics Chrome's behavior by automatically putting background tabs to sleep.Turn Off Hardware Acceleration: Sometimes, your computer's integrated graphics conflict with Firefox under low memory conditions. Go to Firefox Settings > type "hardware" in the search box > uncheck Use recommended performance settings > uncheck Use hardware acceleration when available.

This Method I tried, but did not work-Firefox to use fewer system resources. Can you suggest how to reduce or minimize its memory footprint?

Upgraded to Firefox V.155.0 (64bit). Using Windows 11. The old version when accessing my Bookmarks allowed the option with a right mouse click to open that bookmark with the option "Open in New Tab". That option has disappeared. How do I get it back?

Current firefox version: 155.0

Since the last few updates, update frequency of title bar of inactive tabs slows down over time. Sometimes there is important info in title bar that should be updated frequently. Are there any flags in about:config that can be reverted to achieve that?

when I went to turn on Firefox this evening, the icon was gone and there was no access to Firefox. The only way I could access the internet was through Safari, which I otherwise never use. This happened 2 or 3 weeks ago but, that time, I was able to find the icon. This time that is not the case.

The new VPN feature is really wonderful. But I'll run through my 50gb practically overnight if I leave the feature on and all my YouTube traffic runs through it.

I would like a feature where I can whitelist (or blacklist?) certain websites. Then, my personal browsing on most websites would be protected even if YouTube could get its hooks into me.

How do I get Firefox to stop flagging Canadian spellings as wrong when English-ca is my top preferred language in settings? I am writing a WordPress post using Firefox on Mac.

I mostly watch YouTube channels on Firefox on my laptop, but recently have had to change over to Microsoft Edge browser to watch YouTube. The reason is that during a channel stream, when an ad wants to play, YouTube and Firefox freeze and the only way to exit the screen is to either attempt to close YouTube or even open Task Manager to shut down all instances of the Firefox software. Firefox is by far my preferred browser and I'm frustrated that it is unusable in its current state. I tried to uninstall and reinstall, but this did not work. Thank you in advance for your help.

I have no saved passwords, yet on some sites that require a login, a selection box shows a couple of choices for a user name/id for me to select. How do I clear these or stop the popup. It';s annoying. Thanks

This shield on the search bar is making firefox on win11 unusable for me. I set browser.urlbar.trustPanel.featureGate = false but it still displays. Why do they keep making these changes, it seems like every month there is a new change requiring setting changes,

I had problem with a certain website, did trouble shooting mode and refreshed FireFox. Website works now but I keep seeing this when FIreFox starts. I set FireFox starts with default Firefox Home. Any suggestion how to correct this nuisance?

I know Firefox is slow when opening Facebook. It's busy blocking all their crap. But recently it's been super slow and non-connective to many sites I visit often. I've Ookla checked my connectivity and their excellent. Logging into sites I've visited before is now taking a long time some having to be resent. IE: www.clevelandclinic.org, local government sites etc.

Hey y'all.

I was messing with devtools before on my own site, and now whenever I go to tetr.io I keep getting "Debugger paused". Clicking the little "Deactivate breakpoints" icon in the Debugger tab in devtools changes nothing and it's still there.

tetr.io used to work on Firefox; I think when I was on 154 was when I last went on there.

I tried to cancel my Mozilla VPN subscription and it keeps saying my subscription is not found yet it keeps trying to charge an old credit card of mine. How do I cancel my subscription without having any customer service reps to speak with?
