Diễn đàn hỗ trợ Firefox

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

Reviewed "Sheribee" earlier issue which apparently involved a VPN. I do not have a VPN but have tried several times in the past week to access IRS refund status site without success. I can get into irs.gov, but am unsuccessful in accessing the refund status site after entering required input data. The issue has occurred only this past week.

I'm unaware of IRS issues causing this problem.

Have not had this issue on any other sites; and I have successful retrieved data in prior years.

I am not saving any sign on protocols with the irs or any other sites.

Running Windows 10. Thanks for any help. BTW I did get refund information using the telephone, but I want to ensure there's not a hidden conflict of some sort with FireFox. Thanks for any help.

Hi guys,

I don't know when and how exactly this thing was added to my firefox behind my back, I don't like it, I don't like Baidu Pan either but I have to use it.

I checked the extensions and add-ons, nothing suspicious was found.

Can you please help me remove it?

Recently I have noticed that where there are drop down lists on websites I visit the drop down function no longer works properly if I am using the Firefox browser. If I click on the arrow in a drop down list box the list briefly appears then disappears almost immediately making impossible to select an option from that list. I don't have this problem if I use any other browser like Safari and the drop down list function used to work on Firefox, so presumably this is a bug unless there is something in preferences that needs changing. I am using v88.0.1 on mac OS Sierra 10.12.6. Any help wud be appreciated

my pc had friend so when i got a new one i lost all of my firefox data, how can i get all of it back so i was forced to start all over, i lost all my, bookmarks, tabs, history and saved passwords

I have a new business website http://affordable-tutors.com/about-our-tutors and I tried to put in my video https://youtu.be/EQxd_cowXPg

but it gives me the following error. Website will not allow Firefox to display the page if another site has embedded it

What can I do?

Yes, I own all the rights for that video.

I am getting a certification issue when trying to visit 2 specific sites which are some of the most visited sites in the web: https://www.google.com and https://www.youtube.com

The error it shows when trying to visit these 2 pages, is SEC_ERROR_UNKNOWN_ISSUER.

I have tried to troubleshoot it and follow the solutions recommended at: https://support.mozilla.org/en-US/kb/error-codes-secure-websites#w_the-error-occurs-on-multiple-secure-sites

however none of the solutions described in this guide worked to solve my problem.

In that guide, one of the suggested solutions is to scan my system for any malware. I used the following: Windows Defender Maleware Bytes AntiMalware Karpersky TDSSkiller however the results are all clean.

In the guide, it suggested that I check the clock as well. The system clock however is synchronized.

Last, I have resetted Firefox Profile but this didnt fix the issue either.

I shall note that the issue appeared yesterday and so far nothing helped fixing it. Not even the system restarts.

The issue about visiting these two sites, is limited only to Firefox.

I can access https://www.google.com and https://www.youtube.com without problems using Google Chrome and the Opera Browser.

Also, Google Mail and Google Translate work fine on Firefox. These two sites can be accessed with Firefox without causing any SEC_ERROR_UNKNOWN_ISSUER errors.

Ever since I started using Firefox which was months ago, I've been getting this "Hmm. We're having trouble finding that site" page multiple times a day when opening links to various websites. Refreshing the page makes it load correctly. I've tried troubleshooting this in the past but didn't spend too much effort, but enough is enough. Things I have tried:

• Disabling all extensions
• Disabling hardware acceleration
• I am using the default theme so there's nothing to disable there
• Clearing the cache
• Checking my internet connection (I'm connected and everything else works)
• Flushing my DNS
• Resetting Windows, which included reinstalling Firefox (I did this to fix something else, but still)
• Disabling IPv6 and DNS prefetching
• I am not using a Proxy

I feel like I've tried everything. What else can I do?

Windows 10 - Lenovo Thinkpad X1 Carbon This fall after an update attempt, Firefox started trying to update every time it was started. Deleted Update files in Program Data. FF would restart normally one time. Update data files were always replaced and the update on every startup continued - over and over and over. Tried refreshing FF- same thing. Uninstalled FF this AM and tried to reinstall when I get the following error:

XULRunner Error: Platform version "94.0.2" is not compatible with minVersion >= 94.0.1 maxVersion <= 94.0.1

No FF - HELP!

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

Firefox Browser uprated to 92.0 today. Previously whilst browsing Ad's were showing; today I have no Ad's displayed but have not enabled an Ad Blocker on Firefox. A site I use extensively cannot now be properly viewed; I get a message to turn off Ad Blocker. I have set Enhanced Tracking Protection to 'Off' but am still unable to obtain full functionality, I am using standard Firefox Privacy settings otherwise. I am able to browse the site properly using MS Edge. I have deliberately refrained from using any AD Blocking on my part so as to ensure the site in question can be properly viewed. The only Firefox extension being used is Kaspersky Protection; I get the turn off Ad Blocker message both when Kaspersky Protection is on or off.

Firefox tabs crash repeatedly for a particular email website that I am using. Specifically, the tab crashes when I click on an link to open an email and see the email contents. The tab will not crash every single time, just occasionally (i.e. sometimes I am able to read an email without the tab crashing, other times not). I do not think that the timing of the crashing has anything to do with the email contents (e.g. length, format). I also do not think that the tab crashing issue is happening for any other websites. The crashing started recently, sometime late December.

I installed the latest version of Firefox, and I cleared the web cache, but nothing has changed.

Any suggestions?

google.com and google related websites doesn't load at all. For example, gmail slowly loads, but loading icon never disappears, loading icon is always shown and then often it shows 'reconnecting' message. This works OK in Chrome.

Steps to reproduce: 1. Open Firefox without VPN - all loads well. 2. Enable VPN - stops loading. If I then disable VPN - it starts loading again.

If I restart Firefox it starts working OK, but after a while stops working again.

I have searched for this problem, and only come across outdated information about Youtube's intentional changes to slowdown Edge and Firefox in 2019. This is not that.

When I load a new youtube video, the video will buffer as normal, and then buffering stops. Then there is a delay of about 10 seconds. You can see from my screenshot that the buffer is filled just fine, and playback begins about 10 seconds later. This also happens if I skip ahead/back or to any position in the video. This firefox install is on a new install of Windows 11, with a new xps 13. The previous xps 13 with windows 11 didn't have this problem, and I don't have this problem on my desktop setup with windows 10.

I use a few addons: decentraleyes, ublock, duckduckgo and I have privacy protections set to strict. I have tried a few troubleshooting steps and the problem persists. Things I have tried:

• safe-mode
• fresh install
• installed additional codecs
• used user-agent workarounds to show as a chromium based browser
• turned off hardware acceleration

The problem doesn't happen on chrome, but it does happen on Edge, which is strange. Because of this, I'm wondering if there is something going on with codecs. In the firefox screenshot posted, the codec used is vp09, same with Edge. But in Chrome the codec is av01.

I needed to have Windows 10 wiped and reinstalled from my laptop, and the guy who did it cloned my files to save everything. I saw instructions on another post on how to find the bookmarks file under Profile, but it didn't do anything after confirming that it would wipe out all current bookmarks. What am I doing wrong?

I was using Firefox, had one window open...browser was moving slowly so closed it. When I went to reopen-even in safe mode-it loads windows I had open and then suddenly crashes...I cannot refresh it as I have a lot of custom settings and bookmarks...this is the crash report I keep getting, can anyone help me please?

Hi, The program SEEMS to start but Firefox does not load one singel page. I get no errormessage but firefox does not even try to open pages.

Also, if I try to go into "settings" nothing happens (no errormessage, but settings does not open).

I have tried to uninstall and reinstall Firefox. Does not help.

If I try some other bowser everything works fine. The problem started after I did a total uninstallation of Office365 (does not need to be depending on it but it could be a connection).

Have searched the web without finding a solution and now I ask for help here, I really do want to keep using Firefox but currently it is impossible.
