Firefox Community Forum

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.

Hello, a locally hosted application has a web interface which tries to send a data (POST request) to a remote resource (which is under my control) yet the web browser (Firefox ESR 128.9.0esr) blocks this resource request saying in a developer console (F12) this:

• NS_ERROR_GENERATE_FAILURE(NS_ERROR_MODULE_SECURITY, MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT)

• Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://myRemoteServerIP/request.php. (Reason: CORS request did not succeed). Status code: (null).

I suspect that the CORS blocking is a result of the first (SSL) error, AI also told me that I can configure my remote server/resource (e.g., using Apache, Nginx, or PHP) to include the necessary CORS headers in its responses and indeed the remote server of mine has such lines inside a PHP script that is receiving the request: header('Access-Control-Allow-Origin: *'); header('Access-Control-Allow-Methods: POST'); header('Access-Control-Allow-Headers: *');

The remote resource (server) is using self-signed SSL certificate and it is referenced using IP instead of a domain name.

When I try to do the same request via Private browsing window (without extensions), there is no NS_ERROR about self-signed cert. but only CORS one. When I try browser Librewolf 137.0.2-1 (my FF version is older: 128.9.0), the request is NOT blocked, is OK..

My main aim is not to avoid blocking in my browser, but in all main browsers for everyone.

Is it so that this kind of blocking is default behavior in browsers? Is there please any way to avoid that, beside getting a domain name and CA signed SSL certificate?

why is it that Yahoo Finance loads then when adverts load on the page, adverts are there but error 500 is in place for Yahoo Finance. I don't have this problem on Crome but my prefer to use FireFox. When I refresh some times it comes right but most times not. Regards Wes.

Hi. Block Party was just pitched by the WaPo but I see few people here are using it ... yet. Perhaps because you're not monitoring it? I am curious about how it got such a MAJOR free (?) promotion and whether/if there's a way you can or do verify it's claims? For instance, maybe it does what it says it does (clean/close gaps in privacy) but what does it do with the intel it gains?

Is there any chance you can/will verify it in the future?

thanks kindly, steph

With the change in the Privacy policy and TOU for Mozilla, it's been mentioned in several official responses that certain functionality will not be possible going forward without those changes.

If I never use suggestions, hints, or any mozilla services with firefox. Just what functionality becomes a problem that you need to change the "We will never sell your data" and the other equally disturbing "you grant mozilla a irrevocable non-exclusive royalty free right..."?

How about some clear transparency instead of the opaque non-specific statements you've been making?

Loyal users of firefox for the last 20+ years deserve better than this.

Oh, and why can't I remove the search shortcuts for bookmarks, tabs and history, I'd like to map those keys to something else.

how to protect my user name and password to avoid hacker accesibilty because every time he calling to offering products by email, i need support to protect about it.

Firefox worked fine for 3 days on my New win 11 computer. then a white screen but still worked OK .However was now loaded by a third party "quit-hp.com/Firefox and the original program has been removed from my apps. So am unable to clean up the mess and cannot block the app from the computer. My first option is to use Malawarebyte and and HitmanPro to clean up the disk or a complete uninstal and reinstall win 11. this scam is hitching a ride on firefox and pretending to be part of the installation. I am prevented from copying the full address of 3rd party to this post.

Dear Mozilla, I work as a seniro advisor within internet intelligence and investigations at the Swedish customs. I wonder if it is possible to get BSI ( basic subscribe information) from you and if you in that case can provide a link or an email address for our request. What kind of information would you like us to provide.

Looking forward to your reply.

Kind regards, Gabriella

hey=)

look, we need you to remain a "good player" and not do whatever that one bad spirited/posessed person in your group started to seed within.

Stay Private, Stay in the spirit of OG Mozilla.

Dont be the bad guy...

thanks=)

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.

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?
