Firefox Support Forum

There are always PR_END_OF_FILE_ERROR type error given by Firefox when opening secure https:// official web sites of government of India, which end in gov.in Why not firefox browser allow opening such websites which are authenticated government web sites ?

When I attempt to access several websites, I am prompted to turn off my ad blocker. As I have not added a third-party software or extension that does such, I assume it is part of Firefox proper. Search as I might, I cannot find any specific reference to such a thing in "Settings". SO...how can I temporarily disable the 'Ad Blocker' device that is part of Firefox? The 'TEMPORARY' part is important, as I do greatly value the function!

I installed the uBlock Origin add on to stop ads while watching youtube. I restarted the computer. uBlock Origin is in Add Ons, and is switched on. However, I am still receiving ads. First ad is before the clip plays. After 5 seconds, I can end the ad. Second ad is really intrusive. It interrupts the clip. Perhaps I misunderstood the capabilities of uBlock Origin, or how to use it. I would appreciate any recommendations Firefox version on my Windows 7 PC is: 79.0 (64-bit) Thanks.

I need to know how to disable a blocker? I am on a Verizon website page and trying to post a review, I get message to "disable ad blocker" before posting my review.

Hi All,

I am planning to get a new computer and I am wondering if I can use Sync to migrate all my numerous bookmarks and passwords over to the new PC?

Or do I need to export all this info into a file or files and then load that on my computer?

Also if I can use Sync to move all my bookmarks and passwords over... can I store this information on the hard drive of the new pc or is it stored on the cloud?

Can't access my gmail account of Firefox; it wants me to .Add Gmail to your Google Account' . I can access my gmail on Chrome. How do I get Firefox on board? Thanks!

I live with Firefix always in full screen. I Don't like seeing any bars or buttons of any kind.

Befor the latest update, when I moved my mouse to the top of the screen my tabs popped down and in the top right corner was the standard icons for "minimize" "maximize" and "exit".

With the latest update the tabs are there but the 3 buttons have gone.

If I exit full screen (F11) then they are there again, but I dont want to have to exit full screen every time I change between programes which I do every few mins. I'd be popping pages in and out of full screen every few mins!

How do I get the buttons back all the time?

(I have bad English, sorry.) Hello! May I ask? Is it possible to officially download older versions of the FireFox browser? And at the same time that they work and open sites. Just, I have an old netbook, in general, all new browsers do not work well. Thank you in advance for your answer!

even when disabled my background colour keeps reverting to black in firefox I have disbled dark option in themes but it still reverts. I have set text to black and background to white.

I am unable to print from Firefox Browser. I get the following error message "An error occurred while printing" . I have tried updating to the latest version of FF 84.0.1 (64-bit), doing a Refresh, following the Support suggestions for printer problems, editing my profile etc. To no end. I have no problems printing from other browsers such as Google and Microsoft. If I can not get Firefox to print, I will be forced to use these other browsers. Please Help.

I've been not able to access any website 'cause of this PR_END_OF_FILE_ERROR I clearly checked it and connected all the networks but it's not accessing any website, i need help ASAP
