I have used Firefox since before it was called Firefox. For the last 3 years I have been using it without problem on my 2017 iMac 27". Suddenly a few days ago I started getting this a message 'The application “Firefox.app” can’t be opened.' I have uninstalled, including removing all folders and files containing Firefox or Mozilla and reinstalled versions 75.0b9, 79.0 and 80.ob5. None of which worked. None will open in safe mode. However, if I boot my computer in safe mode, it works. Return to standard mode and nothing. I have followed every suggestion I can find on Firefox's site and Apple's site. It just plain doesn't work. I love Firefox, hate Safari and tolerate Chrome. I would appreciate some help.

Occasionally network connections will stop,meaning that I won't be able to connect to a website and websites that I'm on (like Youtube stops buffering but video keeps playing) won't load new content. When I click on a extension I don't see the extension menu,and only a white bar underneath the extension. This usually lasts around 1 minute and happens daily.

Firefox somehow got corrupted and I had to reinstall. In the process I lost all my bookmarks. I found a number of JSONLZ4 files in an "Old Firefox Data" folder and copied the most recent one to my desktop, then tried to do a restore from it. Nothing. What am I doing wrong? Thanks very much...the loss of my bookmarks is a major catastrophe, any help in getting them back is much appreciated.

In my main profile, restore session stopped working. The option is set, but it doesn't work. It worked for 3 years since I created this profile, but now it doesn't work.

Recently, this profile has been crashing regularly on quit. I quit (CRTL-Q) and the window does away, then 10 seconds later, I get a pop up message saying that firefox crashed.

Just a moment ago, I had a system crash and now this profile refuses to restore my session. When I started it, there was a new session and all the backup session files contain new sessions, not my tabs. Lost all tabs.

Anyone else seeing this?

After updating to Firefox 79.0 on August 10th, I am unable to load Gmail. When I try to go to Gmail by either 'gmail.com' or 'mail.google.com' the browser will load but will never take me off the current page and eventually stop without any error messages.

I have tried deleting all website cookies and data, reinitialize storage, clearing browser cache, disabling hardware acceleration and trying in safe mode. Deleting cookies and data fixed it for several hours but then it quickly stopped working again.

I've attempted to load Gmail on both Chrome and Edge and it worked fine on both of them.

I've been having frequent trouble starting Firefox for the past month or so.

Sometimes I get the Windows error message that Firefox crashed and asks me to restart, check for problems, or debug the application.

Sometimes Firefox will open on a "New Tab" and fail to load my default home page (http://localhost/default.html). A dot on the left side of the tab cycles back and forth continually.

I'm using Windows 7 Home Edition with IIS installed.

Thank you.

I am responding to jscher2000, who posted to my question a short while ago about the loss of my bookmarks and being unable to restore. Thanks very much for the fast response. I checked the Places Database section of Troubleshooting, and as you suggested it does say "The places.sqlite database is sane", and "The favicons.sqlite database is sane". So I assume that's good? Now what do I do? Again, many thanks for the assistance.

My windows 10 laptop setup is an external 1920x1080 at 100% zoom and the laptop screen set-up as secondary, at 2560x1440 scaled at 150%.

Firefox (79.0 (64-bit)) works fine on the primary (unscaled) display, but on the scaled display all the drop-down menus (extension, but also hamburger from firefox) are too small, and the contents are either not entirely visible (typically for the extensions) or need a scrollbar (like the main firefox menu).

I tried to run firefox with extensions disabled but the problem persists.

I think this is a Firefox bug. Is it true and if so, how do I report it?
