Firefox supportforum

Dear Team. As always thanks for a great browser... I had a Firefox update come through this morning (through the browser prompt). After installing the update the pc became extremely sluggish. Thought it may need a restart so restarted the pc but pretty much the same issue? Slow, delayed and sluggish.

I checked what was running in the back ground and other than the usual microsoft nonsense and background stuff it showed 30 instances of Firefox running taking up 82% of the memory. I always have one browser with 8 tabs running by default.

I'm running an i7 processor with 8gig of ram which should be more than ample. Any thoughts / ideas would be most welcome. Once again, thanks for the best browser....

Best regards, Kev Brown. Brocott UK

Some files appeared on my Desktop folder. when i erased them my Tabs and profile got deleted. then when i log in my profile the Files return on the Desktop folder.

my problem is why is this happening?. Firefox was installed on default installation drive, and it has been 8 months or more but only now this is happening.

i don't tweak anything on this browser, just browsing and consuming content.

Yesterday morning I opened my RBS online banking, without any problem. Late yesterday evening I tried repeatedly to open my RBS online banking without success. I would go through the usual log in process and end up with a blank screen. I tried a Firefox refresh which made no difference.

I am receiving this error message when I try to log into my router. My router has a certificate from Let's Encrypt.

What settings do I have wrong?

Regards.

I use Firefox to watch movies on YouTube, Netflix, and many other sites.

I always make these movies full screen. Usually, that means that my computer will stay awake while the movie plays. But after 4 years of this working without issue, I started having problems last November.

Since then, whenever I make videos fullscreen, they'll display as normal, but after a few minutes, my computer's screensaver will come on. It's like my computer can't recognize that the videos are fullscreen. It treats them as regular videos and kicks into whatever power management settings I've set up

I've tried disabling all my add-ons. I've tried changing all my power settings. (Whatever power setting I choose, that's what ends up happening: screensaver at 10 min, 15 min, etc.) But nothing I do can get my computer to recognize fullscreen videos from Firefox .

This only happens with Firefox. When I play full screen videos in VLC, my computer does not go into screensaver/sleep/etc.

I'm running Firefox 123.0 on Linux Lite (Ubuntu).

The only way I get this to work-- and it doesn't always work-- is if I restart my computer, Firefox will sometimes behave as expected. But if I finish a movie and let my computer go to sleep, then the next time it wakes, I'll have the same problem again.

All help appreciated. Thank you!

I am using Mozilla Firefox on MS Windows 10. I want to add an autoconfig file to lock some preferences. As per this doc firefox.cfg and autoconfig.js need to be saved in the same directory where firefox is installed. https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig

I had downloaded firefox from the Microsoft store. Firefox is installed in the %programfiles%/WindowsApps folder, which is owned by 'trusted installer'. Because of this a normal user cannot write to this folder, not even with Admin access.

Is there a way to set auto config without changing folder permissions? Can I save the firefox.cfg and autoconfig.js somewhere else other than the install folder?

Running on an M1 Ultra Mac Studio, Firefox struggles to play 4K videos in recent days where it would've normally performed fine. I've never had troubles watching 4K YouTube on Firefox, until the past week or two. There are no other applications running, and only the one tab open in Firefox. Just a regular 4K video. Why won't it play properly? Why does it start buffering randomly when I can see my network is just fine? Why does it just randomly skip 10 seconds every minute or so while playing? This exclusively happens on 1440p or 2160p (4K). Please fix this ASAP.

I get pop-ups from a scam site basicdataconnection.com. How do I stop them? My pop=up blocker is activated.

Hi,

I can't seem to be able do disable search suggestions, or at least make them appear after my bookmarks and browsing history, i.e. I used to be able to type "gm" and the first option would be my Gmail, not a google search for those letters.

If "provide search suggestions" is on, the box to show them "ahead of browsing history in address bar results" is greyed out and can't be toggled; if it is off, then the sub-option turns on.

This makes the autocompletion feature basically useless.

Is there some other way to change this? I've tried restarting the browser after a settings change, with no luck.

Thanks in advance.

So ive been using firefox for a long time and never had any problems. for 2 weeks that ive had Bitdefender Total Security i've been getting the red alert for Online Threat prevention that says: firefox.exe attempted to establish a connection relying on an expired certificate to staging.pango-coupons.besttoolbars.net. We blocked the connection to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk.
