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?

As the title says, I cannot get MP4 files to play in Firefox, which renders several websites unusable. These sites work in Edge just fine, but I cannot get them to work in my preferred browser. Everything is up to date, and I have all the codecs I could ever need installed, as well as the Windows N Media Feature Pack. The browser has been tested several times in troubleshooting mode, and I've even gone as far as running Windows in safe mode with networking to try to isolate the issue. I cannot get it to work at all. This is the 2nd device I've had this issue on, and it's driving me up a wall.

Any help or advice would be greatly appreciated.

Hello, ever since we moved endpoints from Firefox ESR 91.13 to 102.3, it has become impossible to play any media with Firefox.

No video will play in youtube, for instance (it just loads endlessly as if it would start, but it doesn't).

Can't use radio websites either. Anything with a "play" button (video or sound) does nothing.

This has been tested with a clean profile, a clean install, after allowing autoplay in the settings.

Is there any info on what exactly changed between ESR 91 and 102 that might explain this ? There has been no system change, If I reinstall 91 instead it works again as usual.

No issues anywhere else on the endpoints (Edge, Windows), this is on Windows 10 if it makes any difference.

Tanks for any help on this.

Over the past few days FireFox v. 99.0.1 had been non-responsive on a tab.

Got to the point I had to close FF and tried to use cCleaner to clear cache/history etc.

However cCleaner could not proceed as it claimed FF was still open.

Using Windows Task Manager I found FireFox was "Suspended" (screenshot 1)

I then terminated the task - so cCleaner could proceed.

Then FF appeared to work OK. Until the next time....

It just happened a few minutes ago closing FF - using cCleaner - once again FF was "suspended" and had to be terminated in Task Manager.

On FF help it said Update to version 100 which I did BUT the update got stuck on the FF Update - for several minutes (definitely over 10 mins) so I had to terminate the FF Updater using Windows Task Manager (screenshots 2 & 3) again used Task Manager to terminate that.

FF appeared to open OK even showed the version 100 What's new tab.

BUT when I used FF help to check version I got Restart FF to update to version 100 (screen shot 4) Perhaps the last might temporary due to terminating the what appeared to be stuck Updater, but it was worth mentioning.

PC details: OS Name Microsoft Windows 10 Home Version 10.0.19044 Build 19044 System Model HP Pavilion 590-p0097c Desktop PC System Type x64-based PC Processor Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz, 2808 Mhz, 6 Core(s), 6 Logical Processor(s) Installed Physical Memory (RAM) 8.00 GB

Any help appreciated.

Thanks,

Vincent

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. :/

Today, my daughter received a notification that the Dragon Professional Web Extension has been disabled (see attached image). This was done because the extension supposedly executes remote code and collects user data.

My daughter, a mathematics professor, has very limited use of her hands. She is dependent upon Dragon to do her job. This is not something she just likes - she has a disability and she NEEDS it. Disabling this extension will make her job significantly more difficult, and there are capabilities that the extension provides that she may not be able to duplicate with workarounds.

PLEASE, make the extension useable again. This is an accessibility issue for disabled people - it's not just a fun addition to the browser. If necessary, add some sort of acknowledgement checkbox so that she can acknowledge that she is taking some risks in using it.

One other thing. Disabling this extension with no advance warning was a disservice to all disabled people who depend on it. Had this occurred in the middle of a semester, the effect could have been catastrophic. As it is, she may need to spend the rest of the summer trying to figure out how to do her job without it. You have really, really done an extreme disservice here.

Hello team,

I'm not sure what happened, but I was not able to open Firefox after restarting my PC. I currently run Windows 11 on a fully upgraded rig.

Up until today, I have been trouble free. Error 1: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I tried several options - and have been googling/trying several steps for a couple of hours (after each step, I restarted the PC):

1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Attempted to use Command Lines to open Firefox https://wiki.mozilla.org/Firefox/CommandLineOptions 3. Opened Profile Manager and attempted to create a new profile - when I did this the new profile would not display in the Profile Manager, but it would display in the Profiles folder under Appdata [I tried this multiple times] 4. Deleted the profiles.ini file

After deleting the .ini file Error 2: "Your Firefox profile cannot be loaded. It may be missing or inaccessible." 1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Opened Profile Manager and attempted to create a new profile. After following the Profile Wizard, another error pops up: "An unexpected error has prevented your changes from being saved."

I am completely stumped. I hope you can help, Sean

On this site: https://www.orange.pl/twojekonto/zaloguj I can't force firefox to remember username (no problem with remembering password on next step). In older Firefox without WebEx there was addon which allowed to manipulate forms to prepare proper autocompletion data. This addon is not supported with WebEx anymore due to lack of proper functions. Instead Firefox Dev Team claims that mechanism built in current Firefox is enough for such tasks and mentioned addons are not needed. Seems it is wrong thinking.

I tried different approaches to save username for mentioned site but without success.

I can't access certain websites when I attempt to leave feedback. I'm told to remove blocking. I clicked on the shield and turned off Enhanced Tracking Protection on those sites. I also added the sites to the Exceptions list in Privacy & Security (Manage Exceptions). My Browser Privacy Settings are: Custom Choose which trackers and scripts to block. ✓Cookies: Cross-site Tracking Cookies ✓Tracking content: Only in Private Windows ✓Cryptominers ✓Fingerprinters

But I still can't access the sites.

Which settings do I need to change so I don't get blocked by the websites?

I've run into a troublesome error with Firefox for probably eight months now, so I have not been using the browser. Whenever I attempt to install ANY add-on from the Firefox add-ons page, I get the message "[Add-on name] could not be installed because Firefox could not modify the needed file". Furthermore, attempting to download the add-on file manually (should it be available on a github page or the like) leads to the same message or a notification that the download failed.

As a matter of fact, downloading almost any kind of file on Firefox inevitably fails. The exact notification is shown in the upper-right corner of the browser window, where downloads are shown, and beneath the file in question is an indicator that says "Failed". Everything from .png to .zip to .exe appears in the downloads queue for a second, then fails.

I have tried every solution the Firefox add-on troubleshooting page has suggested, including solutions suggested in other threads, such as deleting/creating new profiles. I have also attempted to completely reinstall Firefox on multiple occasions, as well as the refresh Firefox option.

To recount, the following troubleshoot solutions did not work:

--Everything on the Firefox add-on troubleshooting page --Restart Firefox --Refresh Firefox --Create new Firefox profile and attempt to install add-ons from there --Delete and renew the extensions* files from the profile root folder --Modifying the xpinstall.signatures.required in about:config (true or false, doesn't matter) --Modifying the extensions.alwaysUnpack in about:config (again, true or false, doesn't matter) --Double-checking allow list and permissions on local firewall and antivirus software (the app is protected, add-ons are allowed) --Disabling antivirus software --Running Firefox as Administrator --Reinstall Firefox --Restarting PC

If I want to download a file or add an extension, I need to switch to a different browser such as a chromium-based one or Microsoft Edge to download the file. In the case of add-ons, I switch browsers, download the file, and select the "install add-on from file" option under "manage extensions" in about:addons.

One final thing. It seems that sometimes streaming sites won't work on Firefox (even with ad-blocker disabled or the site allowed through the ad-blocker), and sometimes video won't properly load either. These things work fine on other browsers.

I really like Firefox as a browser and enjoy the privacy it provides built-in. I didn't have any of these issues up until last year and I was forced to switch over. I would really appreciate any help with this.

A while ago I made a Firefox account with my Yahoo email address as the primary email, and my Outlook email address as the secondary email. Eventually I realized that I didn't need my Yahoo email account anymore, so I deleted it, forgetting that it was being used as the primary email for my Firefox account. Now I can't remove my Outlook email from my Firefox account without verifying my Yahoo email account, and I can't even delete the Firefox account since it was made under the Yahoo email account as a primary email address.

Now I can't use my Outlook email address to create a new Firefox account either.

I used Samsung smart switch to transfer data to new phone. When I tried to sync Firefox on new phone with my PC, old phone and tablet I was asked to type in the authorisation code. No matter how I have set my e-mail accounts no e-mail is received in my spam folder or in-box. There is no way to contact Mozilla to resolve this. I have not received any e-mail to state that my sign in was blocked for security reasons nor have I received an error code. I setup a bugzilla account and tried to request that my account be unlocked but there was no way to do this. All it has done is to create an entry that I reported "Zarro Boogs found". How do I get my account unblocked as the advice on the help pages is no advice.
