Hi,

We are having an issue with Firefox 77 x64 on a Win10 (1909 - 18363.836) When we start it, nothing happens. Sometimes, we can see for half a second the dialog box asking if we want to start in safe mode but firefox stops before we have time to do anything. We tried to start firefox from Powershell in safe-mode without any success. We started firefox to reach the profile manager (.\firefox -ProfileManager), the profil manager starts and is crashing after half a second We noticed an installation of firefox 32 bits remaining. We deleted the folder. We desinstalled Firefox and reinstallled it many times without any success. (we tried the long term version without any success) We deleted the profile folder without any success.

What could we do?

Thanks in advance for your help!!

And do I do that thru syncing or do I have to something else?

Firefox Installer gives error "VCRUNTIME140_1.dll was not found"

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.

How will I be able to keep v68-based Firefox ESR during the Jul-Sep 2020 "overlap period"?

Just planning ahead here...

I have Firefox 68.9.0esr (the latest esr version). I have Firefox set to “check for updates but let me decide whether to install them.” I have read that a new version of esr based on Firefox 78 will be released on June 30, 2020, but that there will be an approx 3-month overlap period during which one can alternatively choose to use additional 68.xx esr updates.

If I want to take advantage of this overlap period and keep using an up-to-date 68esr as long as possible, how would I do so? After June 30, will I be offered only 78esr versions, or will I be offered the “overlap” 68.xx? If the answer is that I will be offered 78esr as of June 30, how can I obtain the overlap 68 esr updates instead?

Thanks.

My present iMac is failing rapidly and I will be replacing it with a new Mac very. I do not have a Time Machine backup. The only info I really need is how to copy off, to an external drive, all the bookmarks and bookmark structure), extensions, and add-ons I have added to Firefox, and then add them to Firefox on my future Mac.

Do I just copy the Firefox app to the external drive? I looked in the Macs' base system Library and Preferences, and in my User files, but I do not see anything related to Firefox.

My old (current) and failing Mac is running the latest version of Catalina,

Thanks for any info!

I'm downloading lots of JSON files on day-to-day basis and I'm tired of selection download action because FF doesn't have a "remember" checkbox for it (see image below).

You can reproduce it: go to any site that allows you to download jsons, e.g. https://petstore.swagger.io/#/pet/findPetsByStatus

If you execute any request there will be a `Download` button If you click it you will see a popup similar to attached one: no "remember" checkbox.

How do I make it remember my choice?

My FF version is 77.0.1 (64-bit), Windows 10 2004.

I am restarting FF. I am on 76 and the install is for 77. A window pops up asking for my credentials to install a new helper tool. I don't recall seeing this before and it looks a lot like Oracle's Java installer that tries to install a bunch of crud. In that case cancel continues with the Java install. In this case, Cancel stops the FF upgrade.

What is this tool and why is it not described better to know have a better guess as to whether it is safe to install?
