Firefox initially popped open a window stating that I already had another copy open and so wouldn't open. After some investigating, I found a fix and followed the steps to delete profiles - possibly the cause of the errors. (I had applied this solution once months ago and it had worked then.) Subsequent to this attempt, I was unable to open Firefox - even with the creation of new profile(s). Given the situation, I deleted Firefox entirely by dragging into Trash and emptying the trash and re-logging in. Downloaded a clean new install from the Mozilla website. Although the DMG file downloaded fine, when I attempt to copy app to Applications folder, the system hangs. So now there is no way to re-install Firefox?!

This link /post seems to reflect my condition: https://support.mozilla.org/bm/questions/1240427 However at the given location on my computer, I only had a FB video plugin - even after i deleted that, there is no change, i.e. remain unable to implement a fresh new install of Firefox.

Suggestions? Thanks! RT12

p.s. Using a different computer to post this. When I get a chance, I'll go back to the one with this issue and see if I can post the "troubleshooting information".

I read the recommended articles for this problem on the Firefox website and deleted the files: Delete the following files: extensions.sqlite , extensions.sqlite-journal , extensions.ini , extensions.json and Restarted Firefox. That didn't work. I also turned everything in Bitdefender off and tried to install the update, but that didn't work either. The Notice says: Firefox update Important Firefox update available. Click "Install" to continue. Program firefox.exe Verified Publisher: Flash Player Necessary measures: Now click on “Continue to Installation ” and then on “Add” to complete the process. See attached screeshot When I click on Install a window comes up that says: "Allow newsoftware-update.com to install an add-on?" When I click on "Continue to Installation" the window that says "The add-on could not be downloaded because of a connection failure" appears. See attached screenshot. So far I have not been able to get past that. Please help. Thanks

Too many functions have been lost. I have a more up to date laptop but I'm not going to update the OS on my main desktop computer because too many other software programs would need to be updated - such as video editing and Adobe programs - which work fine as they are. Sadly my browser in future will have to be Safari or Chrome, which work fine with the current OS.

New update has completely ruined my browsing. Completely changed everything and removed all my saved data, a lot of links to websites, saved passwords and everything else just gone after an update I didn’t accept or get asked for. How the hell do I get my old information back. I don’t even know if my account was through this accounts email or not. It’s really pissed me off

Usually when i clicked on pdf files, they would open in a new tab where i could view them. More recently, it would always ask what to do with the pdf file. Today when i clicked on a pdf file, it asked me again, but when i clicked to open with firefox it just started to open 90+ new blank tabs, untill i forcefully shut down firefox. Up untill today i didn't change the my firefox options, but it just started changing the way it reacts with pdf files. Today i tried changing the files and aplications options to preview in firefox (i read in some firefox articles that this option was suposed to be the one i used to have), but it would still ask what to do with the file, but when i clicked to open in firefox, it would also download. I then changed to open with firefox in the options, but it would just open 90+ new blank tabs. If i tried to always ask (which i find very annoying, considering i spent +1 year without it always asking), it would also download even if i specified not to download but instead open in firefox. When all failed i tried to reset all firefox options, but thje same problems still happened, after that i updated firefox (something i did for the first time), but still the same.

Firefox did an automatic update and totalled my old Firefox, or so I thought. I deleted Old Firefox. I downloaded new Firefox. Old Firefox reappeared with bookmarks, but New Firefox also appeared without bookmarks. I am completely mystified as to what I should do. Delete new Firefox and continue to use old Firefox? Or is there some way to install new Firefox and keep my old bookmarks on which I rely? I find this unfortunate migration disturbing and am wondering what went wrong and what else is wrong with new Firefox and the migration process. Thanks to anyone who can help me on this.

There needs to be a way for users to revert to the previously installed version of FF with all add-ons, settings, etc. restored completedly the way they were before the upgrade trashed all customization or deleted/disabled all add-ons.

When an upgrade is available and I try it, I always(?) get a message saying that the Firefox Upgrade failed and that I should download and install the latest copy. Can you guess why I now know to avoid that suggestion?

It takes way too much time to tweak the configuration of a frequently used program such as a Web broswer only to have the whole damn thing revert to stock settings whenever an upgrade comes along.

I can see why many settings or installed add-ons might not work if a particular upgrade involved many significant changes to FF, but users should be given the choice of not upgrading and never Syncing Firefox until they are sure that all the perceived bugs in the upgrade that break things they like as-is I like are fixed and that Syncing will not do more harm than good from their perspective.

Newer or allegedly "improved" is not automatically better in the eues of the owner/user. Just look at the millions of people who have avoided downgrading their Windows 7 or 8 installtions to Windows 10. The latter seems even more defective by design.

Why cannot FF be upgraded without breaking much of what users found good in the previous version, often due to their customizations? I wonder if the upgrades could be done on a feature/function basis in most cases. I certainly understand why the upgrade to FF Quantum had to be an all or nothing procedure...but EVERY upgrade since then?!?

Every morning, when I first turn on my computer, I a have to spend the first 5 minutes setting up my Firefox again because of a "new profile". I have to re-enable all of my add-ons and configure them as well. Why does this happen every single day and is there a way to prevent it? If not, then I'm done with this browser...such a colossal waste of time for something that I shouldn't have to do. I don't have to completely set up Chrome or Edge if they do an update...all of the pertinent stuff is brought forward.

I have Firefox 73.0 (64 bit) on Windows 7 and am moving to Windows 10 using Laplink (yeah, ok). Laplink does not seem to see this version of Firefox to transfer over. So, I used sync on the Win 7 unit for everything and downloaded Firefox 73.0 (64 bit) to the Win 10 unit, and then logged on and synced. Everything seemed to move over except the browsing history. How do I get browsing history to transfer to Windows 10? Thanks.

My Firefox on one machine was having worse and worse problems, but it's OK on the other machine (same Firefox account). So I decided to do a clean re-install of Firefox. I uninstalled via Windows 10 add/remove programs, and as I was doing so, I noticed an old version "Mozilla Firefox 58.0". I tried uninstalling that; it asks me if I want Firefox helper to make changes . . . I hit yes, and then it quits without doing anything. But the entry for version 58 remains.

From guidance on a forum, I went to c:\Users\<username>\AppData\Roaming\Mozilla\ and deleted it. I also deleted c:\Users\<username>\AppData\Local\Mozilla\.

I've rebooted. That old version still seems to be there.

How do I get rid of this, so I can have a clean re-install?

I have seen that 73.0 has caused some major problems for some. Since I installed 73.0 (64-bit) however, I have only one problem but it has a high impact on my use of Firefox. The setting for downloads was not changed and remained set correctly for "Ask me for file location" which has worked daily previously on previous Firefox versions. I have tried to change the setting to a specific file location and then change back to no avail. The specific location works fine but returning to the "ask me" option does not change anything. Not sure what to try or do to proceed...
