Firefox Community Forum

alright guys you need to fix your browser, it crashes everytime i try to play a youtube video.. i searched tou site for fixes and NOTHING worked. you vanilla version of the browser was perfect then yall had to go and do the microsux thing and screw it all up by adding this that or the kitchen sink. i have submitted numerous reports yet no resolution. if you guys dont fix your crap i will move on to another browser and recommend to all my friends n family to do the same.

Firefox, specifically the Windows version, has started generating PR_END_OF_FILE_ERROR errors on https:// web sites. What I find interesting is that Firefox says the page is not secure in the address bar - even though the page is secure. Firefox on Mac and IOS do not have this issue. I'm also running Bitdefender Anti-virus with Encrypted Web scan. With that feature turned off, blocked pages seem to work. I found yesterday that logging out of Sync while Encrypted Web scan is on allowed the blocked pages to load.

I deleted Firefox and re-installed it, thinking I'd fixed the problem. No such luck. I've tried all the other fixes I can find but none of them work. This is clearly a Firefox issue and not an issue with Bit Defender since it only occurs (and has been widely reported for years) with Firefox for Windows.

On a side note, even support.mozilla.org gets blocked.

Anyone have a real fix that will work?

I have a million accounts because I am relentlessly harassed and hacked. All of my accounts. I could not say for sure but maybe it has something to do with divorce...maybe not. Idk. Im no expert and I have no idea where to go or how to make it stop. I have done all the changing passwords and just making another account but its ridiculous. Whoever changes my recovery info and I am helpless. It drives me nuts!

I have developed a web application (wordpress) that shows a number of thumbnail images, each connected to an mp4 video. There is custom javascript such that if a user selects a number of thumbnail images, creating a playlist, all of the associated videos will play back in the order selected. This works perfectly in the Chrome, Edge, Safari, and Opera browsers. However, in Firefox, rather than playing back the videos in sequence, after each video, a gray screen appears in the video player (JWPlayer) that says the file is corrupted. The mp4 files are not corrupt since they work well in the other browsers. Also, once that gray box appears, by clicking the "Play Video"button the next video in the sequence will play but this must be repeated after each video in the playlist. Is there a setting that can be adjusted so that sequence will play in FIrefox? Is there a default setting that prevents the sequential playback?

Any help would be appreciated

How do I restart with add ons disabled.? There is no option as stated https://www.wikihow.com/Start-Firefox-in-Safe-Mode

seeing this big blank area doesn't help me think of something to ask/say! Just makes my mind go blank. Did I say I'm 85 years of age. We thought things got better when we got to use electric typewriters!

My firefox webbrowser used to update almost every time a signed in. It has not let me know it has updated lately. The last few days we are getting constant popups whenever we go online in Mozilla Firefox. Each of them has your logo & gives increasing warnings about a virus asking me to click on a link - We can either x out or click ignore, but have to do it 5 or 6 times.. over & over. I cannot snip it or print screen it as it disappears or just tries to copy the blank background.

I do NOT want to click on these links as it may well download a virus rather than remove it. What do I do? If updating Firefox will help, how do I do it?

Sorry I really do not know anything about web development but would appreciate some help. For the past week or 2 metamask extension will not open properly. Upon clicking the icon it just perpetually loads. I have the same issue when using any kind of wallet connect to metamask, be it on uniswap or metamask website for example. I have cleared cookie cache. I have tried both disabling state partitioning using network.cookie.cookieBehavior. I have also tried setting this to 0 to allow cookies, these did not work. I have of course restarted my computer/browser. This is definitely an issue with my firefox because I am able to use the metamask extension in chrome. I have attached screenshots of the console & debugger from the metamask site in the hopes it has some info that anyone may be able to provide advice. In the debugger & in my searching I see an issue with "source maps", in my debugger it is saying "no source map found" - again I cannot apologise enough for my lack of understanding but if this is my issue would anyone be so kind as to explain a fix in laymans terms.

Since the last update, or perhaps the one before that, both I am my husband have been having trouble with tabs. We are both on Windows 11 but machines from different makers. It is my habit when researching to right click links to open interesting looking things in a new tab and then go back to read all the tabs in turn, the info sticks better that way than reading>searching>reading>searching. I have never had trouble with this before no matter how many tabs I had open, I have a powerful laptop.

Suddenly Firefox will act as normal and then after a bit the tabs don't load.I don't mean the rightclick/open in new tab doesn't work but the tab which opens will have nothing on it. Sometimes they will open properly in a new window but sometimes not. Also on the Daily Mail website the page doesn't seem to complete somehow; the relaod icon doesn't appear and you have to click the 'cross' to amke the page stop trying to fetch something (I presume). This doesn't happen with any other newspaper site.

I have refreshed Firefox, I have checked all my settings, I am not using a VPN or private windows, I have changed About:config dom.ipc.processPriorityManager.backgroundUsesEcoQoS to false to get rid of the eco leaf symbol showing in task manager I have Norton as my virus protection. I have closed and reopened the browser and switched the laptop on and off :-) I have read many things on this forum but I have'nt tried this yet as YouTube is not involved https://support.mozilla.org/mk/questions/1384439

So I am out of ideas and it is really annoying me. I have found many other people have this problem, I have been using Firefox for about 20 years and I don't want to have to change but will if I can't get this sorted out! Any help gratefully received, Mary

Beginning about a week ago, I have been unable to open LinkedIn Sales Navigator from Firefox. I am able to open Linkedin from Firefox and able to open Sales Navigator from other browsers.
