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?

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

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.

Firefox 103.0 (64-bit) Windows 10 Pro N 21H2 19044.1865

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,

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. :/

Until the most recent update of Firefox, I was able to access atrribute data of a GIS map feature on the GIS Open Data, State of Michigan website:

https://gis-michigan.opendata.arcgis.com/datasets/2020-voting-precincts/explore?location=44.909859%2C-86.310800%2C6.97

Now, I can not click on any feature. I can do this, however, using Chrome. What is the issue, here?

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

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?

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 have sent several emails and get no reply, how am I suposed to fix check or see my saved passwords if they all look like this...3b4a3f36-7056-4eee-bcb3-2b0838fa07e1

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.

Accidentally added a misspelling to the Firefox dictionary. Thought it would be easy to locate and edit the dictionary.

Enabled 'show hidden files.'

On XYplorer, and Windows File Explorer can find not a single trace of 'persdict.dat' in my profiles folder.

It would be really helpful if you could advise what the next step would be. Thanks.

I need a FireFox feature that allows me to access the typical Cable Modem Gateway Web Manager addresses (192.168.0.1, 192.168.100.1, etc.) even when they have no security certificate.

I have been using a Arris SURFboard SBG6782-AC Wireless Cable Modem Gateway (purchased at TARGET) for over five years without significant issues. About three weeks ago my MoCA network began having issues. I tried to login to the WEB Manager of the Gateway at (192.168.0.1) using FireFox. I got the following FireFox Msg:

Secure Connection Failed

An error occurred during a connection to 192.168.0.1. Peer using unsupported version of security protocol.

Error code: SSL_ERROR_UNSUPPORTED_VERSION

   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.

This website might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox.

I finally used an old version of "Internet Explorer" which allowed me to bypass the security warning and connect via a direct ethernet port of the gateway. Evidently someone (Spectrum claims they didn't) downloaded a different firmware version into my Gateway. (D30GW-EAGLE-1.5.4.0-GA-10-NOSH) i.e. not the factory original version. The WEB Manager interface is different, password requirements are enhanced, the MoCA feature can't be enabled, and it seems Arris no longer provides a security certificate for the 192.168.0.1 Gateway address.

Considering the complete lack of cooperation of Spectrum and Arris, I think it is unlikely that I will ever be able to recover the factory original firmware; So... How about adding an "exception" feature to FireFox settings to allow me to at least access my "unsecure" Gateway. I really don't want to go back to using IE. By the way, I wrote this on a WIN 8.1 HP laptop. My main machine is a Dell XPS8300 running WIN 10.

Thanks, Robert R. Hurley

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 note that there are 399 posts referring to this problem. The problem has existed on my PC for about 4-5 months.. DELL support has checked my computer, we have cleared cache and browser and tweaked other controls but nothing helps. I have no problem using Google Chrome. If so may people are having the same problem surely Firefox should be making an effort to fix the bug??!! Just drafted a reply to you from Firefox site but as frequently happens message appeared -

 Something about oops and an error message. When it occurs drafts do not save and messages do not transmit.

Sorry the screen print will not copy across.

I use Firefox as my main browser and it is inconvenient to have to swap between Firefox and Chrome

Can Firefox please fix this problem?

thank you mlmg

I'd like to permanently delete an account that was set up on a former employers email address (email which I can no longer access). Unfortunately I have no secondary email address recorded in the account and all the options on my account page require that I authorise any changes from the email account which I can no longer access.

Is it possible to delete the account?
