I was running just "regular" Firefox on my Windows laptop. Yesterday my help desk had me upgrade to Firefox Extended Support Release to install a corporate email security certificate. I did not know when I installed this version of Firefox that it would overwrite my existing browser, and when it did, I lost all of my add-ins, extensions, bookmarks, etc. I'm hoping to be able to restore my old profile with all of the existing data I had. If I have to "downgrade" to regular Firefox I think that's fine since I just needed the ESR to install the security cert and that's complete now.

I looked on the about:profiles page and I have two other profiles, default and june19 (I presume the latter is from June 2019?), but I don't know how to determine which one is the preferred one. When I clicked Launch profile in new browser, it instructed me to create a new profile to protect my information and I hesitated to do that because I'm trying to restore an old profile, not create a new one. In case you can't tell, I'm not an advanced software user, so give instructions like you would to a 5-year-old or your grandma... lol. Thanks in advance!

I have been running on Windows 7. Upgraded to 10. Cannot set Firefox as default browser at this time. Do I have to download Firefox again? Will I lose all my saved passwords if I do? Thanks. Janice

After an issue with FF not showing websites properly, I decided to uninstall it according to the instructions mentioned under https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems, section4.

After downloading the latest version and installing that, it was mentioned a new profile was made, but I could import or sync with the old profile to restore settings, passwords, etc.

For some or other reason importing this does not work the way it was supposed to, so I am now stuck with a fresh installation with all previous settings being lost.

Is there a solution, please? Help is appreciated. Thanks

NOTE: I'm posting this from a different machine to the one which has the problem because, well, I can't run Firefox any more :-D

Hello,

The latest beta channel version (installed on 2nd June 2020 at 16:00 UTC+2) of Firefox for x86-64bit Linux now requires GLIBC 2.18 (for libxul.so it says). This was not the case a couple of weeks ago when I last updated the Linux machine's Firefox.

Unfortunately, the highest version of GLIBC available on Redhat Enterprise Linux 7, through the usual yum channel for our servers, is GLIBC 2.17.

Anyone else stumble upon this? Any solutions (except upgrading to RHEL 8 ;-) )? At worst, I could downgrade Firefox to a previous beta or stable version.

Sorry for the probably noob-ish question. Error message when trying to run firefox:

XPCOMGlueLoad error for file /usr/local/firefox/libxul.so: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by /usr/local/firefox/libxul.so) Couldn't load XPCOM.

I teach at James Madison University and must download zip and jpg files for instruction. Sometime within the last 48 hours, Firefox would not download any jpg or zip files. For years now, this has never been an issue. The tab indicates connecting, the grey shadow passes through the tab and then nothing. I have tried this at different academic sites and the same happens. There is no problem downloading zip or jpg files using Chrome. What happened and how to fix it?

When I go to support, and type in "how do I find the current version of firefox for windows", I get: "Found 2923 results for ‘how do I find the current version of firefox for windows’ for ‘Firefox’ " but none address the issue of how to determine the most current version number. I notice Firefox says that I cannot upgrade, I must download a new version, with no explanation. The download is a version-unidentified executable called "Firefox installer.exe" I would consider this suspicious behavior in most downloaded software. What is going on? This seems like basic information that should be immediately available. I had a popup that said I am using the most current (71.0) version (I am using v 71.0), which appears to be incorrect. Googling this question has no Mozilla hits other than "Release Notes" which might lead one to guess 77.01, althoughn Wikipedia thinks just "77".

I had to create an account just o ask a forum question?

Hi there, after the last update, I getting from time to time the annoying information that there is an update available for firefox. How do I disbale the update information? Please only answer is your awnser is not like that: "updates are important....." or "its not possible"

Hello,

Since yesterday, I've installed Windows 10 Pro, and when I download files with Firefox, it downloads for like 5 seconds and after that it says "Failure" (I don't know the word in english but in french it's "échec") I tried every solution on the help page of Firefox, can you help me please !

I was using FF 56.0.2 so I still had my addons. A recent windows 10 update made it unable to load any webpages. In trying to fix that problem, I decided to install the current version of firefox in addition to the old version. But when I did, it never gave me the option to install in a new location, and it overwrote my old version.

I want to reinstall the old version on this same computer (and hopefully figure out how to get it seeing webpages again). I have a backup of that original profile that 56.0.2 was using - and want to use it so it sees all my old logins, bookmarks, etc. I'd like to do it so that each version will automatically use the correct profile without having to tell it myself each time I open firefox with the profile manager or something that way.

How do I reinstall the old FF version (I have the right installer already), copy the old profile back up into it, and make it so that that old version will use that profile, while the new version uses the profile it's already currently using? I've found information online before about how to do this, but honestly found it to be confusing and wasn't sure how to actually go about doing it.

Thanks in advance for help walking me through this!!

Have a desktop and 2 laptops, (old and new). Need to share 100% of the desktop's Firefox profile directory structure with the 2 laptops. Meaning from the desktop;

scp -rp .mozilla/* laptop:~/.mozilla/

For security reasons, (and yes, I do work with government mandated private information), I can not share anything beyond my computers. So, the cloud is out of the question.

All I want is to copy my home directory from the desktop to the laptops, when needed.

Hi. Just got a new hard drive. I have lost all of my bookmarks and can't figure out how to get them back. I have tried the Help instructions, without success. Thanks!

Running Windows 10. Recent update I lost most of my pending and storage contents. My attempts to restore through Profile APPData not successful to the point I gave up. Old guy, not too computer literate. Now getting an update message when I start Thunderbird and after I decline I get the message that it "can't update to latest version, download fresh copy & we will help install." Again I have declined as I am reluctant to do this and lose more email files however as I choose not to update, I continue to get the messages every time I open Thunderbird which is annoying. I would like the original files back and update Thunderbird and have no more problems.
