Firefox Community Forum

I have several websites in my own LAN. They run on HTTP. When I open one of these sites Firefox forces me to jump through hoops before I am allowed to open the intended webpage, because they are not running HTTPS, nor have a certificate. The security mechanism is valid for remote hosted websites, and I like the functionality.

But I own, operate and trust my LAN based websites, but I cannot prevent Firefox from complaining about them. I must do the song and dance to finally be able to open the webpage. All webbrowsers (Safari, Firefox, Chrome) do this, and it is very annoying

Solution: Allow the user to create a whitelist, either based on the website's ip adress, mDns name or blanket subnet. Come up with a solution that is easy for the user, and inspiring for your competition!

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?

My Youtube video stutters every 6-10 seconds. When I turn off my HW acc off, this issue happened. Turning the HW acc on solve it, but the thing is if I have my HW acc on another problem came up, which is my Firefox will starts to blink. Anyone has a solution for this?

For the past few weeks, I have been having problems playing certain Facebook videos. It seems to only happen when I try to play a video that was recorded live. I have tried clearing the cache, I've tried a private window, and I've tried safe mode. I still can't get the video to play. However, when I copy and paste the url to Safari, it works fine. I have been able to play "live" videos while they are actually "live"; it's just that they will not load when I try to play them later. I don't have any problems playing videos which have been uploaded to Facebook; only those which were recorded live. The videos just show a circle in the middle as if they are trying to load but nothing else happens. The length of the video does not matter; it happens with short videos as well as long ones. The screenshot image (of a random "live" video I found) I am uploading shows a partial black circle in the center, which is a spinning circle in realtime. I have circled it in red.

There must be some setting I accidentally engaged by hitting some kind of key combination but there are the contents of 2 separate tabs on the FF window. Maybe it's some new 'feature' they added but I right clicked on the tab and nothing looked like it applied to this. What is it and how can I make it stop? I just want each tab to have the contents for that site. If you know what's going on, maybe explain it simply and I'd also like to thank you.

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

Sometime in the last week or two, every page starts with a banner that says "you must sign in to the internet to continue". I'm already/always signed in. On those few occasions when I click on the network login link (rather than clicking X to dismiss this dangerous and wrong banner), it shows a very dangerous site and says that site is prohibited. (As it should be.) So why is the banner demanding that I log in (forcing me to click X to dismiss it)? This feels like your site has been compromised, that some malicious actor is forcing this prompt on every page. (And even after I click X to dismiss it, it reappears 10-15 minutes later.

I have spell check turned on in setting to check as I type. And yes I have two dictionaries downloaded and installed. But as I am working inside a program and I have to enter data into a text field, if I want it spell checked I have to right click and then click on Spell check for every field that I enter text into. For a while last week it was working without having to do that, and I had done nothing to make it happen. It was nice. Since then I realized I want spell check on. But I can't figure out how to set it so that it turns on for every field that I click into to enter text. Any ideas?

After Firefox update on my win 11 laptop, I had to reset my Firefox custom homepage and all my search settings and all my security settings. This should not happen. I did not lose my bookmarks or anything else.

Yesterday, I could log into my credit union account with Firefox on my Win10 desktop; today, after a Firefox update, I can't. I switched to Chrome, and logged right in. Called the credit union and was told it was the new Firefox update. Can I switch back to the prior Firefox version? Thanks!

I am building a game that uses the canvas. Since the last update a lot of images are not displaying. I have always used Firefox to test the game and never had a problem. Test on other browsers have no problem. I have tried on localhost and on a live server. I have fingerprinting turned off.

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?
