In the past few days, the block video autoplay option is not working. It had been working properly for years. I have video autoplay turned off in about:config and the option to block autoplay is no longer available under the settings menu. What settings need to be changed to re-enable this in the update. This is extremely annoying.

Can't prevent "Show Sidebars" button from appearing at startup

Despite the advice on this question on the forum, the sidebar appears whenever I open Firefox, regardless of whether it's set to display bookmarks, history, or synced tabs. And the "Show Sidebars" icon is glued to my toolbar (the one with the URL & search fields). Whenever I go to Customize and drag it out of there to the Customize box, where the unused icons live, it reappears every time I close and reopen Firefox. BUG.

One piece of advice on the Forum from 8/8/18 says to "Right-click a bookmark and choose Properties, then check in the lower left corner for a checkbox to "Load this bookmark in the sidebar" and uncheck that box." I have no such checkbox on the bookmarks I've right-clicked, so I obviously can't uncheck it. Besides, this would require looking at every bookmark - grossly impractical.

The other advice on 8/8/18 also doesn't work. It says to rename or remove xulstore.json in the Firefox profile folder. Doing this makes Firefox open without remembering much of anything. This is going after a fly with a sledgehammer.

This should clearly be in Options. It is a constant annoyance to have to click the X on the sidebar every time I open Firefox.

Movie trailers will not auto-play after the 30 second intro ad.

After the ad the video remains blank.

This problem also exists when Firefox is restarted in safe mode.

Works fine when using other browsers such as Chrome or Edge!

Please look into this!

My employer has a certain setup, to login to the e-mail a password is needed, this is automatically filled in since we saved the password in firefox. This was setup this way to ensure employees don't need the password. In fact they're not allowed to know the password, however firefox has a show password option, which allows them to see the password anyway:S

Is there anyway for this setup to work? like hide the show saved password button orso? (employees use local accounts, aren't allowed to install anything etc, so just hiding that should be fine if I'm not mistaken) Obviously a master password won't work, since they'll need to fill in the master password when they want to login to the mail, if they can do that, then they can also access the show password option.

Any help would be very much appreciated, basicly we want our employees to login to the mail, without them knowing the password.

Nothing seems to be helping to restore the screenshot option, because I have tried all the suggestions except refreshing Firefox, which I really don't want to do having read comments saying that this lost files and caused problems. I really need the screenshot option. I've looked under extensions.screenshots.disabled and it is set to "false". I restarted Firefox. The screenshot extension is listed in the Help>Troubleshooting Information. So now what do I do? I don't understand why it vanished in the first place. I am NOT good with computers.

Ever since I upgraded to Firefox 63, several trusted websites have stopped loading; instead I get sent to an error page with:

Your connection is not secure

The website tried to negotiate an inadequate level of security.

<www.thestar.com> uses security technology that is outdated and vulnerable to attack. An attacker could easily reveal information which you thought to be safe. The website administrator will need to fix the server first before you can visit the site.

Error code: NS_ERROR_NET_INADEQUATE_SECURITY


This also occurs with https://download-installer.cdn.mozilla.net/pub/firefox/releases/63.0.1/win32/en-US/Firefox%20Installer.exe

Is the problem at my end or theirs? If the former, what do I need to do to return to the behaviour for FF 62?

Everything worked fine until latest Win 7 update, but i have no functioning 'restore point' to rollback to, so i have to find a workaround. Sound works on the PC, i can play mp3's or mp4's fine. But audio from Youtube or FaceBook or BBC Iplayer is absent when i open these sites in Firefox. (yes i've checked for volume and muting, i've cleared the cache i 've tried in safe mode, all without success) I tried one modification to the registry which worked ONCE and not afterwards.....which is of course impossible. If i open the very same sites in Opera...the audio is perfect. WHAT ON EARTH is going on and how do i put this right? Thanks in advance for any insights and fixes.

I just installed FF 63 on a 64-bit Windows 7 machine, and I'm getting SEC_ERROR_UNKNOWN_ISSUER errors at many, but not all, websites. Reaching the same websites via the same URLs using Chrome works fine.

All discussions of this problem seem to lead to https://support.mozilla.org/en-US/kb/error-codes-secure-websites?redirectlocale=en-US&redirectslug=troubleshoot-SEC_ERROR_UNKNOWN_ISSUER, but it's not helpful. My antivirus is Bitdefender Free, which appears to have no option for disabling the interception of secure connections.

Running FF in safe mode behaves the same as in "normal" mode: I get SEC_ERROR_UNKNOWN_ISSUER errors at many (but not all) websites.

Help? As things stand now, FF is pretty close to useless for me.
