Firefox Forum di supporto

When I try to upload something to youtube music it keeps on showing up as an error despite being the right file extension. To test this I uploaded the same files on Chrome and they worked perfectly.

Problem was fixed upon fresh start /or resetting cookies and cache but both are annoying each time as I have to relog into everything each time this error happens.

I just tried to print a list for the browser on Firefox and the new print options are useless. I use to be able to simplify, change background and have more options. This looks like the printing options on Microsoft Edge. I started using Firefox to get away from that. I mean if your going to mimic edge then why not use that browser instead??? Stop changing things. You update every 5 minutes and then it crashes, is to slow or just doesn't work. Slow the hell down and remember people like Firefox because it isn't like the big companies out there. It's a good browser. Leave it alone.

I found out Tor Browser has the Application URL thing disabled, and I want to know how to disable it in Firefox. Is there a flag for it in about:config or something?

I use 3 profiles (work, private and media) side by side. When I open external links I have no control over which profile will open the link. The link is opened right away (so no profile manager interference) in a random profile. I do want it to open right away, but ideally would like to easily set a priority order for profiles to open the external links without having to restart the profiles.

Using the latest 87.0 (64-bit) on a Windows 10 PC.

I always keep multiple tabs open when browsing of my websites that I use everyday. Tabs constantly crash and have to be reloaded. When I switch to a different tab the other tabs crash. Ads and videos crash the tabs. Firefox session crashes all the time too.

I believe something is corrupted and would like to do a complete cleaning of Firefox and install fresh while being able keep all my settings, bookmarks, preferences, addons, plugins, themes, etc.

I need complete step by step instructions or video to help me.

Respected Teams,

Whenever I opened just 5 or new tab in Mozilla Firefox, then My PC starting stuck issue, However MY PC has 16 GB DDR4 RAM, 120 SSD, Core i9-7th Gen,

further in CORE i7-7th Gen Laptop, we faced no issue at all if I opened more the 10 Tabs at a time, No Fans speed increase no stuck or hang issue, why this is happening only with My desktop PC?

Thanks in Advanced!

Hello, I use 2 monitors if one of them has a live stream from Facebook then there are such flashes on the primary monitor while browsing. But only if Firefox is open on the primary monitor. Here is a video of the flickering: https://www.youtube.com/watch?v=AOsjhbInuQQ I had a system reinstall due to an SSD replacement, but the error persists. This error has occurred since the Windows 10 Pro 20H2 update. I have an RTX2070 card with the latest gpu driver.

Thanks for the help!

Firefox 87.0 / MacOS, in safe mode, with and without enhanced protection. Mostly after clearing cache. Server is Apache, running WordPress.

Other browsers (Chrome, Opera, IE) have no problems.

Using HTTPS.

Page itself (HTML) loads correctly. The referenced (linked) files do not load, even though they are on the same server.

When I look at the Network Analysis tab, I see that the CSS and JSS files have no return codes, and show 0 Bytes transferred. It does not show the data coming from the cache. A detailed look at the request looks normal, the answer is not available. When I resend the request I get an answer, no problem.

No messages in the console.

It seems to have something to do with the server, when I deactivate certain WP plugins, the problem disappears. Perhaps the problem is worse when the server is slow... cannot prove this.

I am looking for what I can do on the Apache side to fix the problem.

Thanks in advance, Ron

Does firefox support hardware codec?which version? I am a programmer and develop a product support WebRTC. When install chrome browser, the codec has been install,too. But on my mind, seems firefox only support openh264 which is support baseline and software codec. So have any schedule to support hardware codec ?

I have a specific problem...Firefox will not load a particular web site which it previously did for years. I have refreshed and reinstalled with no solution.

Here is my story (nightmare)... When I try to launch my credit union, Navy Federal, the following appears on my screen.

Access Denied You don't have permission to access "http://signon.navyfederal.org/siteminderagent/forms/nfcu.fcc" on this server. Reference #18.859ec817.1618087497.20456bf6

I can launch other web sites with Firefox AND i can launch Navy Federal with other browsers. On subsequent attempts to launch Navy FCU, I always get the same Access Denied message, however, the Reference # changes. THANK YOU!!

Hi,

I'm new to firefox, I'm trying on this new linux based config to change from chrome to firefox, and I've got an error on most of the different website I'm trying to join : "Hmm. We’re having trouble finding that site." For short it's the server not found error, but I can access thoses websites from an other browser.

I'd like to solve this problem, I already tried ipv6 disabling, and dns prefetching enabling from this help page : https://support.mozilla.org/en-US/kb/server-not-found-connection-problem and it still not resolve my problem.

It often resolve alone half an hour after I started firefox, but it is way too long...

Thanks a lot for helping me !

Matthieu

PS : domains I can't access : github, my school website, youtube sometimes...

So, I've had this problem once already and solved it. Mozilla updated automatically and I lost all of my tabs (over a 100 tabs, mostly with books I wanted to buy / compare prices), couldn't restore the session and had no history. After a dramatic and prolonged freakout, I actually found help on this site and managed to open the correct upgrades.jsonlz4 files with the jeffersoncher scrounger website. I meant to save all of the links in a word file since I no longer trusted firefox to open my tabs after an update, but real life happened. I kept putting it off and was content to have the tabs on hand as a list on the scrounger website. But then ANOTHER automatic update happened and now I no longer find the old .jsonlz4 file - I have a few really old ones (from 2017 and 2019) but the one from around the time period of the first tab loss only has tabs about restoring lost history. I now, just as before, again have no history to find the tabs with the books I want that way. My question is: I would very much like to have those tabs back - some of those books were meant as gifts and finding them the analog way is possible, but very time-consuming. Is there any way I could find the correct .jsonlz4 file (I even remember the date it was modified as shown in file explorer - or should I just give up the whole affair as lost and no longer waste time on it? I'll try reinstalling firefox after I post this message, but given that it didn't work last time, I'm not very optimistic.

Thanks in advance, all the best Ana

Dear Community,

I would like to download this extension: https://addons.mozilla.org/pl/firefox/addon/adblock-plus/ I would like to know how it works. If I will install this extension my firefox will be check hashsum for the files of this extension automatically? Or maybe public key of the organization/company who created Adblock Plus extension? How it is work? Can you tell me? I hope that people from Mozilla now read this and can answer for my question. This is very important for me.

Next question is to Adblock Plus extension. I can read this information: "This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing" so my question is why Mozilla don't recommended this extension? This extension now use 6,678,297 people so this is huge count. It is possible that this extension is not safe and these people now use malicious software? Why on dedicated website for this extension I can't see company name? Why this company is not verified by Mozilla? So my sugestion for people from Mozilla is to change this and check this extension or maybe add some information on website for this extension.

So I should install this extension? My friend use this on Google Chrome and he recommended me this software but I don't know if this is exatcly the same version. Maybe Chrome has verified Adblock Plus software and this is safe but Mozilla didn't verified this and this can be dangerous software because this can be not exactly the same version?

Next question is to adblocker. Why Mozilla can't make their own software to block all annoying ads and due to fight with malware? Example Opera browser have own buil-in adblocker. Why firefox can't do this? Maybe people from Mozilla should do this? This can be helpful because if this can be happen I will be not install any 3rd party software for firefox anymore and I will be safe. Maybe I can send somehow this suggestion to people from Firefox?

I hope that you can help me.

Yours faithfully, Peter

Web pages don't load completely, I get green areas and places where all the letters and characters don't show up. This was after an Edge update.

Thanks, Bill

Dear Mozilla Community,

I would like to suggest you to make built in adblocker in Firefox. For example Opera have this feature so we don't need install any extension. People from Mozilla read subjects in support.mozilla.org? If not where I can send my suggestion?

P.S. I wanted to install Adblock Plus extension but I am afraid about safety so better option is to make built in adblocker to protect from malware. I think that this can be direction in good way.

Yours faithfully, Piotr
