Diễn đàn hỗ trợ Firefox

Just recently when I am on yahoo mail, I randomly get logged off. When I try to log back in, I have to change my password to succeed. I am running out of ideas for password as I have changed it dozens of times. This did not occur immediately after an update. Just out of curiosity, I did system restore to undo the last ff update, but still happened either way. I went thru deleting all cookies, stored passwords and cleared browser history. None of this helped. Virus scans showed negative. I have called att/yahoo tech support and they could not fix this. I have opened my mail in IE and do not have this problem using that browser. But come, I hate IE. So I have windows 7 professional. Not sure of all the pertinent system info needed but appreciate any suggestions.

Ever since Firefox upgraded to version 75, using it has become impossible to use via RDP on Windows Server 2008 R2. The behavior is like Firefox completely hogs down the machine, but more likely seems to be impacting the refresh rate of the RDP session. With Firefox open, mouse begins to trail and button clicks and movement stack up and execute as much as a 5 minute delay at times. I saw a similar report, but not 100% the same, here: https://support.mozilla.org/en-US/questions/1278453

Here is what I know so far...

* Specific to Windows Server 2008 R2, tested on multiple VMs on multiple hosts
* Issue not present on Windows Server 2016, Windows 10, or Windows 7
* Size of Firefox window affects performance, leading to validate RDP refresh issue.  If half the screen is Firefox vs the whole screen, the lag is lessened
* Safe Mode immediately resolves the issues
* Safe Mode with all Add-Ons re-enabled still resolves the issue
* Hardware acceleration on or off has no impact
* Downgrading to Firefox 74 resolves the issue (but this could also be because it made me a new profile)

What other details can I provide? Is there anything else I can try? Does this qualify to report a bug on bugzilla?

Hello, everyone. My Firefox (v76.0.1, Windows 10 Pro 1909) can't access the English Wikipedia (en.wikipedia.org) and some other sites I need to work with. This started happening suddenly Tuesday night.

This is the error (in English, since my Firefox is in Brazilian Portuguese):

Secure Connection Failed

An error occurred during a connection to en.wikipedia.org. 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.

upload.wikimedia.org gives me the same error. The bizarre thing is that Wikipedias in other languages seem to work normally. Other browsers work fine.

Searching it online, it doesn't seem to be a common problem, and it just started happening by itself. I don't remember installing anything on this PC that day. My only antivirus is Windows Defender. I don't use any VPNs.

Tried all solutions I could find on Google. So far I did:

• Ctrl + F5
• Edited the hosts file
• Deleted cert8.db
• Changed network proxy settings to No proxy and Automatically detect proxy configuration (was in Use system settings)
• Toggled DNS over HTTPS
• Went in about:config and toggled network.dns.disableIPv6
• Started Firefox in Safe Mode
• Backed up the profile folder and just let Firefox create a new one
• Rebooted my router

None of that worked.

I work with site builder platforms and since yesterday the error is starting to creep up in those servers, too.

Any ideas? I just noticed that Wikipedia search is gone from the list of opensearch engines also… This is getting increasingly bizarre…

I'd like to know why when I use Firefox often google asks me to show I am not a robot. Yes I use a VPN but this does't appear so often using Chrome. Thank you for any information

I very much would like to switch away from Safari to Firefox, due to a number of reasons. However, I find Firefox has a much higher CPU demand and that's a killer for me. Using latest version for all listed browsers in a MacBook Pro (i9, 16GB RAM), after opening CNN's website (also tried with other websites) and letting all browser just rest there, without interaction, I see this (CPU):

Firefox: 49.5% WindowServer: 26.4% Google Chrome: 16.1% Safari: 5.8% kernel_task: 4.6% (https://cln.sh/TQhV)

Is this normal or expected? (Firefox version is 76.0.1)

Firefox will not let me stay logged in to my ATT Yahoo mail account. I am required to log in every time I launch Firefox. When I log in I always check the box that lets me remian logged in for two weeks but it does not work and I have to log in every time I launch Firefox. This seems to have happened after the last update. I did a complete uninstall and reinstall of Firefox - no improvement. MS Edge will let me remain logged in with no problem. I prefer to remain with my faithful Firefox and hope someone can recommend a fix. Thanks.

I have been using Firefox Send for several months now with no problems. However, at the moment, I upload my documents, copy the link and send my email & link as always and everything seems like usual. But when the link is clicked on by the recipient, the documents are not there and only a blank white rectangle appears on the screen within the Firefox tab. Please see the uploaded image.

I am running Windows 10 and Avast security software (nothing has changed). I tried refreshing Firefox, then uninstalling & reinstalling it, then created a new user account, all to no avail. I have a feeling it's a settings issue on my PC (I had some extra users on my system recently), but I don't know where to start looking or how to analyze the options.

I would appreciate any ideas or suggestions as to how to make Firefox Send work again!

Thank you for your help!

The file (link here) plays in Chrome and VLC but not Windows 10 Firefox or Ubuntu 18 Firefox.

I've analyzed it with FFmpeg, AtomicParsley, and other tools and have found nothing wrong with the file. I compiled Firefox nightly from source and it gave the same error as my Windows 10 install. Screenshot of the full error message attached.

bold textits all in the subject matter...IVE TRIED EVERY TROUBLSHOOTING THING I COULD FIND>>>AND SO MUCH MORE>>>>>i need an remote interface please??????

Recently when I try to use Find in Page (Control F) function on Firefox PC Browser, the whole browser freezes for some seconds. When I change the search word it freezes again. This issue only started to appear recently, and it doesn't appear on any other browser. My Computer has 16GB of RAM, so I don't think that's the issue here. I would be very grateful if anyone has a clue how to fix it.

I have the following message on my Gmail (using Firefox browswer): JavaScript must be enabled in order for you to use UW Mail in standard view. However, it seems JavaScript is either disabled or not supported by your browser. To use standard view, enable JavaScript by changing your browser options, then try again.

Can someone tell me what it is I need to do?

Thank you!

Is there a way of making the Password Required Pop-Up pop-up sooner? I launch Firefox and start typing in search or address, while I am looking at the keyboard the Password Required pop-up appears on screen silently. I am typing away then find I am typing my search or filling in a form online into the pop-up! The arrival of the pop-up is random time wise, could arrive within seconds or maybe in 30 seconds or maybe longer.If the pop-up HAS to appear it should appear when you launch Firefox. I truly find this very annoying, having to re-type, then entering the password then going back to where I was before the pop-up!
