Firefox Community Forum

I'm finding that firefoxcp isolated web content uses a LOT of memory on my Mac Mini. What can I do about this besides not using Firefox. I like the browser and have been using it since its introduction

I accessed the about:support page as part of attempting to diagnose a fix irregularities with logging of history entries. After at most 2 seconds the screen repeatedly began flashing to a black screen. The screen would stay black for up to 10 seconds then clear for maybe 1 to 2 seconds and then blackscreen again repeatedly. It did it on several consecutive occasions so is no one-off

Similar problems occur with Amazon Prime and Spotify but the black screen last significantly longer (over a minute or more) and the cleared screen shorter (milliseconds).

On no occasions have I seen anything that resembles and error message or code.

I restarted Firefox in safe mode loading about:support again with no other tab loaded and it continued to happen. It clearly is not a add-on or extension that is responsible. Sometimes shutting down Firefox (if you can see the screen long enough to do so) clears the problem but not always. Equally switching windows using <ALT><TAB> can relieve the problem but only on some occasions. I've not identified which applications might relieve the issue in such circumstances but suffice to say were I to return to the problem web page it would begin again.

Trying to reset the video card (Windows key Ctrl Shift B) has no effect.

Clearing the cache, cookies etc seems to make no difference and other temporary files

I only clear my history periodically leaving several months of entries available.

I have tried to update the video drivers on numerous occasions and been advised they are up to date on every occasion.

It occurs with hardware acceleration checked on and without it.

Reinstalling Firefox makes no difference and the black screen issues have been happening now for probably 2 years or so across multiple versions of Firefox and before today (when I used about:support which I have not used before) I had assumed it was purely down to third party sites but now having experienced these problems it's clear that at least in part Firefox is part of the problem.

It does not happen with other 'about' functions (profiles,config,processes,memory) so seems specific to the about:support function in terms of Firefox related pages.

Turning the monitor off and disconnecting the monitor from the power supply for the obligatory 10 seconds is the most certain and least disruptive way of resolving the problem. Just turning the monitor off and on again without disconnecting the power does not seem to resolve the issue. Obviously rebooting the system which can waste more than an hour of my time all told shutting down and bringing up software will also clear the issue. Rebooting a PC is no resolution to any software problem.

I am using an HP24i FHD monitor connected to a Dell Optiplex 7060 SFF running Windows 10 Pro Version 22H2 OS Build 19045.5487 and an up to date version of Firefox (version 136.0.1 [64-bit])

The system is regularly scanned for malware and viruses and as far as I am concerned is clean. Standard WIndows maintenance and repair tasks (eg fsck, sfc, DISM) are carried out periodically and there is currently one windows update released earlier this week outstanding.

Please can you advise what other steps I can take (or if it is a 'feature' linked to the about:support page provide a work around in your next release) to address a problem that is becoming an increasing nuisance and yet another reason to abandon Firefox whose performance is becoming increasingly flakey in a number of ways.

PS Your 'educated guesses' about software versions in the help form page are blank. Another feature?

i am looking for a way to protect myself and my children from accessing or having to see / have shoved down our throat content promoting lgbtq. please provide me a blocker to block agenda driven sex ed and ALL LGBTQ content.

Can You explain why you try to inform us about securities and improvements against privacy threats BUT now the Browser try to get access to a personal Folder? Does the Documents folder needed for internet browsing? Please, answer me otherwise I report this weird behaviour to authority. Thanks

Since the update I've had a few issues, most I was able to fix but this one eludes me. Opening up various news sites I get the "Firefox prevented this page from reloading" error at the top and clicking allow does nothing. Anyone know how to get around this error? I'm not looking to totally disable the FF feature that prevents other pages from loading a different one, but just to browse the website after hitting 'allow'.

Thanks in advance.

I have "Don't enable HTTPS-Only Mode" selected and still cannot connect to local sites. Example http://192.168.1.81 is chnaged to https://192.168.1.81 and rrecive cannot connect message.

This problem started after you last week after an update.

All of a sudden my Apple laptop Firefox is responding VERY slowly. It takes about 10 seconds from hitting enter to any screen response. I've tried it with and without my VPN on, and there's been no changes to my Avast security software (that I know of). I've reviewed the settings/preferences without any clue about what is happening and what I could do to minimize it. I've run a speed check which resulted in 287 down and 190 up, so it's definitely NT my network.

For highly encrypted messages and sensitive information each time renewed or discovered for the first time cam be very intimidating for certain people. Based on the facts and past experiences, this has become extremely important to discuss and share knowledge with true and trustworthy people only to ours and others peace of mind and safety.

I just learnt that the mozilla firefox terms of service have been either updated, or previously included, a clause of sorts that states that any content uploaded to mozzilla is automatically given a royalty free worldwide license to mozilla itself. Does this apply to content such as add-ons only or does it apply to things uploaded to other websites(such as social media, forums, etc)

Hi,

I saw that firefox deleted all of its language about not selling user data and that has me concerned. I chose to use firefox in a large part because I did not want my data to be sold and this change has me preparing to change browsers this week. Can you please offer a thorough explanation about why firefox is going back on a policy that it once claimed it "never have and never will"? How is my data being used, sold, and profited off of by firefox with this change? Is there a way for me to opt out of my data being sold?

For the past few days when I use Firefox and Thunderbird my entire screen will randomly start to flicker, at times very quickly and rarely the entire screen goes black for second or two. This behavior immediately stops when I close the app. It does not happen with any other app. I've tried disabling hardware acceleration in Firefox and that didn't help. Both apps are on the latest version and I also updated my video driver. Tried removing the two add-ons I have. I'm on Windows 11 Firefox 136.0.

Dear Madam or Sir.

I am using Firefox for so many years now, with some donations now-and-then, but due to the recent change of data privacy policy on your website, I am somewhat worried...

Firefox is the only browser left which is not controlled by Big-Tech. So if Mozilla has some problems with money, I would prefer to pay a subscription rather than seeing my data sold to some tech company. So if you guys need some money, please ask for some monthly subscription first before making a deal with the devil... I mean, I would rather buy an annual license for Mozilla VPN although I don't need VPN, than seeing Firefox going down the drain. I don't want google to have even more data... Best regards, and thanks for the good work. Dirk

Now that Mozilla/Firefox have joined Google on the dark side, who is everyone switching to? I would like something that works well in both Windows and android. I hear Opera can't be trusted and I don't like how there are like 6 difference versions of Opera in the android app store. DuckduckGo is just badly made IMO. Edge causes some glitches with one of the sites I use most. Should I try Brave? I just want a browser to BROWSE the web. I don't want AI. I don't need a VPN or adblock built in. I don't want a "gamer" browser. A decent local password manager would be nice but I don't want to have to make an account to use it. I know if the product is free, you are the product, so I would almost prefer a browser you pay for but oddly that doesn't seem to be a popular option. Probably because the user data the companies collect makes them more money then people would be willing to pay. Sad times. I miss the 90's.

С ноября 2024 г наблюдается проблема : не загружается игра рыцари и принцессы. Несколько месяцев мне говорили что разбираются а сегодня написали что проблем нет из службы поддержки игры и отправили решать проблему с браузером в службу поддержки браузера mozilla ссылаясь на то что он не корректно работает и у меня старая ос. Страница загрузки https://vk.com/app4019000_26034467 .Мои попытки объяснить что проблема исключительно с их продуктом и у меня все программы игры и приложения работают ни к чему не приводят. Помогите решить проблему я уже не знаю что делать.

Last week, I downloaded Firefox to try out and I liked it. My intention was to keep my personal browsing separate from my corporate browsing.

However, I was shocked to discover that my Microsoft Wallet in my corporate Microsoft Edge had been completely emptied! Puzzled and eager to regain access to my password-protected accounts, I remembered logging into LinkedIn via Firefox just moments earlier. Obviously, Firefox had my passwords. I used MS Wallet to import my passwords from Firefox, back to my Microsoft Wallet.

But how did all my passwords end up in Firefox in the first place? Even if I imported them, does that mean the MS Wallet needs to be wiped? I'm extremely disappointed in Firefox. This is terrible programming.
