OpenH264 fails to install with HTTPS-Only mode enabled

"OpenH264 Video Codec provided by Cisco Systems, Inc." plugin will sit in the "will be installed shortly" status forever if you have HTTPS-Only mode enabled. I have been pulling my hair out for the last few days trying to figure out why I couldn't play YouTube or many other sites videos.

Turns out the site that the library is downloaded from has a bad certificate installed: https://ciscobinary.openh264.org/libopenh264-2.3.0-linux64.6.so.bz2

``` Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for ciscobinary.openh264.org. The certificate is only valid for the following names: a248.e.akamai.net, *.akamaihd-staging.net, *.akamaihd.net, *.akamaized-staging.net, *.akamaized.net

Error code: SSL_ERROR_BAD_CERT_DOMAIN ```

OS: Fedora 36 Firefox Version: 104.0 (64-bit)

I was cleaning out my hard drive and deleting old installs of Microsoft Visual Studio Redistributable packages, and I almost certainly deleted the one that Firefox relies on.

I then attempted to start Firefox, getting the error, "The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem."

I uninstalled, following the clean install directions, and deleting the "Program Files/Mozilla Firefox/" directory.

Then, I ran the Firefox Installer, newly downloaded, and when running it, it gives the same error, "The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." Selecting "Restore Defaults" has no effect either way. The installer then appears to complete in the background, and the Firefox directory is created, along with the executable.

When I run Firefox.exe, it seems to load the program, but any address I type in fails to begin loading. This includes websites (www.google.com) and help/utility pages (about:config). I'm therefore unable to change any settings within Firefox.

I then tried re-installing the "Visual C++ 2008" and "Visual C++ 2015-2019" packages in an attempt to restore that DLL, but that had no effect after repeating the same steps above (clean uninstall, re-install). Which VC++ Redist Package should I be re-installing? Ideally, I should be able to just get a copy of VCRUNTIME140_1.dll and place it where Firefox is looking for it.

I'm using Firefox 78.0.2 and i keep getting notices to upgrade. But the last time I upgraded, Firefox changed the locations of my tabs from below the address bar to above the address bar and also changed the behavior of the address bar. It took me a couple of weeks to find the answers and get things back the way they were. I don't want to upgrade Firefox because I have no idea what it might change this time. Is there a way to keep Firefox from sending me upgrade notices when I don't want them?

Dear community, for some days my Firefox 80 on Windows 10 has shown the message "your system administrator has deactivated updates", when I look under "Help" -> "about Firefox". This is strange, because the admin is me myself, and I didn´t change anything in Firefox or in the Win 10 registry. Has anyone of you had this experience, and how can I possibly fix it? Thanks in advance! Pete

I uninstalled Libre Office and it apparently uninstalled the VCRUNTIME140_1.dll file s part of its uninstall process. From this point Firefox would open but would not connect to the Internet, either by clicking one of the links in the toolbar or typing the address directly. I have tried all the solutions I can find on the support pages, ranging from attempting to copy the file from another location to re-installing Visual C++ from the Microsoft website, both the 64 bit and the x86 versions. Having found and installed the latest version of Visual C++ I now get the error message "The procedure entry point _CxxFramehandler4 could not be located in the dynamic link library C\WINDOWS\SYSTEM32\MSVCP140.dll" at the edn of the installation process, and of course Firefox has not installed. Any suggestions for a way forward?

I was gifted an Amazon Fire Tablet to use for an upcoming hospital/rehab stay. I use Firefox on my desktop and Android phone and want to use it on my tablet, but the Amazon store doesn't have the app. Not sure I trust the Amazon Silk browser, but I may have no choice. I am not a tech savvy person! I don't know the difference between a bit, byte, or buttercup. If there is a way to install and use Firefox on my tablet, and sync with other devices, I would like to do so. Please explain how to do it as though you are talking to a 6 year old (who probably knows more about this stuff than I do, anyway). Thanks. rennylloyd

I’m running a windows 8.1 computer with several open tabs in my browser. This computer crashed and I can’t get back into windows to sync up (I’ve tried booting from various sources, automatic repair, etc. it just won’t boot up). I hope that I’ll be able to extract my important files from my hard drive. I’m setting up a new windows 10 computer. My question is, can I copy over a file from my old computer to my new computer that Firefox will recognize and open up the tabs that I was last working on from my old computer? I have not synced, but the last time that I was able to use my old computer I did close Firefox cleanly, and I was able to log off from windows with no serious issues. Hopefully there is a file that I can copy over which will simply allow me to continue working on my open tabs. Thanks in advance.

I use multiple Firefox profiles. Normally, Profile Manager always appears at launch.

But lately, if I launch Firefox while a profile is already open, it just opens a new window in the current profile. The only way I can get Profile Manager is by typing firefox.exe --profilemanager.

For the record, I don't have this option enabled: Use the selected profile without asking at startup.

bonsoir

I need to send my PC to the vendor (FNAC) for reparation. I want to clean my confidential files before sending it. Concerning firefox : how to desinstal it from my PC only, and reinstall it after repair with all the previous parameters and setting already installed ( list of passwords, ...)

said differently, I don't want to cancel it definitly because I use it on another computer and I want to recover it after my PC repair.

If you can help me I will really appreciate

I am using Firefox Nightly. It receives updates every day, but most of the time I cannot restart Firefox as soon as update is available. I want to delay it till next natural restart (ex.: night), however, Firefox shows notification about the available update. It's a minor issue, but seeing notification every day and having it to close every time gets annoying very quickly. I want to disable update notification but keep automatic updates. How can I do this?

When I open the file "pftm4b0j.Default User" it looks like all my data successfully migrated from my old PC. But when I launch Firefox, no bookmarks, no passwords, no add-ins, no nothing.

So I recently installed Firefox beta. It installed on top of main firefox. Now I am in beta version 84 but if i try to open regular firefox release version 83 it says running an old version will corrupt profile data. It just has an option to create a new profile, so i am asking if there is a way to import my settings from my original profile or make my original profile run on version 83 or should I just wait for version 84 to be released in main firefox.

How can I get my settings and bookmarks from a cloned image of my old HDD. This is pretty annoying and making me think about leaving Mozilla. I've done what a support page advised and copied my data from one 'profile folder' (from the image) to another (internal drive). Not helping and displaying a 'The bookmarks and settings will not function properly' error message. I did not unfortunately create a proper backup prior to transferring drives so can't restore that way, assumed that things would more or less be a seamless sync through my Firefox account.

Would appreciate help here thanks.

Lately, every time I download a photoshop file, it now opens Photoshop and opens the file. How do I disable that from happening? I just want the file. I don't need to see it open. This has just been happening recently and I don't always need to open the files right away. It just slows my progress down and it's annoying! Thank you in advance!
