Firefox Support Forum

After I boot my computer, I can access any of the sites I usually use, but only once. If I then close the site and attempt to open it again (or to open any of the other affected sites), I get the following message: " Secure Connection Failed

An error occurred during a connection to phoenixcommons.cohousing.site. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

The site shown in the error message above is the one I most ofen use, but other very common sites (e.g. Google.com) exhibit the same problem:

" Secure Connection Failed

An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

Yeah, right. I'm supposed to contact Alphabet and inform of the problem?

In contrast, some sites (e.g. The New York Times, The Washington Post) are not affected.

I can paste affected URLs into another browser (I used Brave) and access them with no problems.

I have two monitors; I keep my taskbar on the right monitor and run Firefox on the left monitor. For some reason, whenever Firefox gets minimized, the window moves to whichever monitor the taskbar is on (I've done some testing to confirm it is specifically the monitor the task bar is on). Because I also run a program called max.to to separate my right monitor into different sections, this action of minimizing to, and restoring to, the wrong monitor is also resizing my Firefox window.

Is there any way, any option I've overlooked, that would get Firefox to minimize and restore to whichever monitor is is actually running on?

I've attached an image that shows, as best I can get it, the window moving over to the task bar monitor when minimizing.

Within 24 hours this weekend I was notified by my anti virus application (Avast) that they are no longer supporting Firefox browser (to concentrate on Outlook and Chrome), and a political news website that I frequent (Meidas) blocked me with a "captcha" type puzzle. The website said my browser was mimicking robot or bot use. I was presented with a puzzle requiring me to slide a tab rightward. It repeatedly told me I had slid the tab incorrectly. I believe all of this happened after an update of Firefox about the middle of last week.

Once again Firefox has decided to take over and change all my settings! I had finally managed to prevent it updating, as each and every time I had to reinstall all my setting and extentions from scratch. Today, it decided to clear all my preferences and change itself to its own default settings. OK, so I can change my profile option, except all three are using the same defaults: I appear to have lost all my settings and extensions entirely. OK, I'll copy from my backup, but once again the three backup profiles are being overwritten with the defaults. Even my third backup of last March overwrites to the defaults! How and why is Firefox managing to keep overwriting my defaults to its own preferred settings? How do I stop it doing this and regain my own preferences?

I also tried Sync and now I am getting bookmarks from over five years ago! And once again my settings are changing to the defaults. Surely a Sync should overwrite with the current bookmarks and settings not just keep adding more and more. I am now in a right mess again. Back to losing everything with updates. I am a great believer in the 'if it ain't broke don't fix it' mentality, but Firefox has broken itself and is refusing to allow me to change to how it used to be! How do I restore my own preferences and prevent Firefox from changing them to what it wants.

The menu bar at the top of Firefox is extremely small. The size is about 1 mm. I have tried all the supposed fixes and none of them work. I have a new Macbook pro using Firefox.

Hi,

I'm experiencing a problem on Firefox 125 and 126 on Red Hat Linux 8 & 9 and also on Ubuntu 20 and 22 systems.

We have a proxy pac which we have tried loading from an http url, or a local file and both produce the same result.

• Launch Firefox, no access to Internet sites (i.e. no proxy)
• Enter settings and Reload proxy pac
• Proxy works perfectly

Is there any way to force the proxy pac to load on Launch? Why isn't this the default behaviour? or am I doing something wrong?

Thanks

Sir, my hp desktop PC is having -- windows10, Firefox, connect cable Broadband with 100mbps speed, Ethernet, periodically updated. I am very much fond of watching English/Foreign language movies having English CC/Subtitles, online streaming, generally on paid channels e.g. Netflix, prime video, Hotstar, you tube etc. I am not proficient in English language. To read the English CC/subtitles, I have to pause the streaming, read the subtitle and then start the streaming (pause-start, pause-start). After about 15 minutes watching the film, the screen becomes black (no video), with a no signal detected message. But audio/sound remains continue. Then I switch off the PC, restart it, and watch the movie for next 15 minutes., then again black screen.This cycle goes on. But When I watch the film continuously, without pause-start function, then there is no black screen problem. In my opinion this repeated pause-start function causes the black screen problem. Without pause-start function, I cannot watch these movies. I tried some online mentioned solutions without success. Please help me in solving this problem in a simple way as I am not perfect in computer science. Regards.

My firefox disappeared after i found out someone using Windows 7 used my hotmail account address.I dont know how to rectify this and get my firefox back and change my email address with both Mozilla and Microsoft Outlook

The blinking screen is on ebay but it just keeps on blinking. I have tried other programs and it only happens with this one and only with ebay. This is the new tab stuff: https://www.ebay.com/itm/401568771184?_trkparms=amclksrc%3DITM%26aid%3D777008%26algo%3DPERSONAL.TOPIC%26ao%3D1%26asc%3D265563%26meid%3D7245a46a376945799ec6d6e8ae3176fa%26pid%3D101967%26rk%3D1%26rkt%3D1%26itm%3D401568771184%26pmt%3D1%26noa%3D1%26pg%3D4375194%26algv%3DPersonalizedTopicsV2WithDynamicSizeRanker%26brand%3DFintie&_trksid=p4375194.c101967.m162920&_trkparms=parentrq%3A88a4a82d18f0ad8bbb523870fffffa70%7Cpageci%3Ab38440d1-149b-11ef-b242-1adf3ab78462%7Ciid%3A1%7Cvlpname%3Avlp_homepage&afsrc=1&mkevt=1&showcs=1

Thoughts?

ive built a new pc and have a flashing program popup every 10min. upon assistance from a really good pc guy, we've found its a firefox default browser agent with a long code.

its not listed in my scheduled tasks, eyt runs every 10min. only thing close to firefox would be thrunderbird, but iirc, mozilla and thunderbird are not longer the same company. either way. i need this thing to stop running every 10min.

Hi,

The Lower Toolbar is quite handy, with for example Roboform.

Unfortunately, the way it's implemented, it comes above the lower part of the browser window, instead of being inserted at the bottom while the browser windows height is reduced.

That hides the search box when you type Control-F.

It would be nice if this could be addressed in a future release. I am using Firefox Developer 127.0b2.

I hve discussede the matter with my banks IT-department, but they answer me that recently they have heard about the same problem concerning Firefox login and said that the problem have to be fixed by Mozilla/Firefox

On my Macbook Air M1, Firefox's UI and default scaling is perfect on my Retina display, but if I move the window to my external Philips 1080P monitor, some - but not all - interface elements are very over-sized, which makes Firefox unuseable on any external monitor I connect. (I have tested this with multiple other monitors)

I am getting to the end of my tether with Firefox. I have used it for years but the increasing issues are driving me to distraction.

It will not display comments on the Daily Mail UK website, The Telegraph UK site and the screen is scrambled if I try to use Ebay Philippines. I am not a computer expert but I have tried to follow other peoples suggestions with no luck.

I cant see the point of persisting with FireFox unless these issues are rectified.

Any suggestions would be very welcome.

Firefox - latest version, in Win 11 updated version, on my home server, will not load google.com pages, but intermittently works OK - frustratng. Other browsers, eg. Edge and Chrome access sites as normal on my laptop on my home network. My laptop using Firefox will load google.com pages when on another network. Is it my server, or Google, or Firefox doing this ?? Please provide any advice on solving this problem.
