I cannot play mp4/h264 videos on websites, but I can download the file and play it in the browser just fine (ffmpeg is installed).
== From twitter web page: error in web console:
For example, on twitter i get a "the media could not be played" placeholder and this in the web console:
HTTP “Content-Type” of “video/mp4” is not supported. Load of media resource https://video.twimg.com/amplify_video/1149302678771683333/vid/1280x720/qFCcMLAnjR_MBans.mp4?tag=13 failed. home
The video on this page can’t be played. Your system may not have the required video codecs for: video/mp4; codecs="avc1.42E01E mp4a.40.2"
== Local file in firefox
When I put that mp4 link in the address bar, it gives me a download dialog, I can download that file, and play it in firefox from the command line:
firefox qFCcMLAnjR_MBans.mp4
== Local html file with control element:
The same file plays fine also when i open a local html file with the vide controls element. So why do I get those errors when this is viewed on the twitter website?
Any pointers appreciated.
Thanks!

Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection.
What can you do about it?
www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.
The issue is most likely with the website, and there is nothing you can do to resolve it.
If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

My Credit Union's "Bill Pay" system no longer permits access in Firefox 68: get an error page claiming cookies are disabled. They aren't, and the CU's help desk is unable to suggest more than to ensure 'Cookies' is unchecked in 'Content Blocking', and to be running TLS greater than 1.0. (I believe TLS is a server-side issue, but… <shrug> WDIK) Unfortunately, the page is served up by some JavaScript so I can't try "allowing" it.
Chrome displays the page just fine.
Any suggestion will be appriciated.

Latest version of FF 68.0 has re-enabled multiprocess and won't allow me to disable via about:config.
I've been with FF since pretty much the beginning, it's the only browser I recommend to friends, family or clients. Since 10e and the whole multiprocess roll out, I've "fixed" peoples slow and unresponsive FF experience by disabling this useless feature and H/W acceleration.
Now my mailbox is full of complaints about slow unresponsive browsing, plus it using more system resources leaving clients with less powerful machines with real problems.
C'mon Moz, we've been mates for decades, stood by you when everyone was looking at whatever MS was waiving at them, laughed at Google when they tried to play with the big boy, but now I'm feeling sheepish about my claims of Mozilla putting its users needs first, not forcing features on users, giving its users a choice enabling a freedom that you don't have with Edge or Chrome
Please give us back one of the remaining freedoms we have left, don't be MICROSOFT!

After a recent automatic update my old problem with Firefox Quantum came back. Every time I open Firefox browser I get multiple 4-6 firefox.exe running in the background processes. When I go into details and try to end process tree it crashes my browser. When I open Firefox it starts all over again. I have gone into about:preferences and
De-select ‘Use recommended performance settings’ Set Content process limit value to ‘1’ from its default value
I have also gone into about:config and switched browser.tabs.remote.autostart to false. Still have the same problem.

Basically this happens at any time and it wont let me close Firefox without task manager. in task manager it shows up at system interrupts which uses over 90% of my CPU and at the same time Firefox is using over 10 GB of ram. i have had a look at some fixes like disabling hardware acceleration and stuff but none have worked so far.
How to Disable E10s using Environment Variable MOZ_FORCE_DISABLE_E10S - 1

I need to disable E10s. It causes Firefox 68,0 (32bit) to display a Blank Page when Firefox is closed and I launch a Web Page from my Email Client. I have to have Firefox open first now before clicking on a Website url from the Email Client. This was the same problem I had two or more years ago when E10s was first implemented. I disabled it back then in about:config but Mozilla have disabled that option in Firefox 68. It's stated you can disable E10s using Environment Variable MOZ_FORCE_DISABLE_E10S - 1 but I'm not sure where to use that. I put it in my Windows 10 Environment Variables (System Properties/Environment Variables) but it did not work. I am using Windows 10 32-bit (Both Pro and Home) and the problem exists on all computers since upgrading to Firefox 68.0. I need to disable E10s again.

I have an Addon acting up, Webroot Filtering Extension. I can disable it, but I would like to remove and download fresh. The 3 dots by the extension does not have option to remove like the other Addons. Webroot is no longer showing the check mark when doing a search. There is a clear circle where the check mark should be. I am not sure if this started when I updated to Windows 10 1903 or when going to Firefox 68? I have disabled and enabled Webroot Filtering Extension and that doesn't help, restarts don't help.

Before these changes, when I opened Firefox, I could pull down a menu and see my bookmarks. I can't now and I can't figure out what to do from looking at the articles. I loved having my bookmarks like that and I don't know where they are. Or how to get them back. I use an iMac OS X 10.11.6
Please help! I'd prefer to remain with Firefox but not if I can't make it work.

I have installed these add-ons. Ad blocker, password manager, and privacy browser.
After changing the settings in Firefox, my ad blocker and password manager disappeared from the menu bar. I see the add-ons in the extension list. Uninstalling, re-instaling the extensions do not bring the extension icons back. I tried to do a "re-install" using the Firefox "re-install" button, but my extensions did not show up again.
I had to completely uninstall Firefox (which does not remove Firefox settings from the computer ---- WHY?!) delete the registry entry, re-install Firefox and re-instsall the add-on extension to get them to show up again.
But when I go back into settings, make changes, the add-on extensions disappear again.
Which settings cause this?
