WHY is it that every time I try to search for something in Firefox it takes me to Wikipedia? I cannot use Firefox any longer for searches. Everything I try to do ends up as a Wikipedia issue. I cannot escape it, I can't delete it, I can't do anything with Firefox any longer.

Firefox won't stay downloaded to my computer. I am having to download it multiple times, especially if my computer has updates.

On a separate note, when it does actually stay on my computer over night, it never keeps me signed in to my Firefox account. I have to log in to it daily to have my bookmarks and passwords.

Also, it never remembers the theme I have picked for it. I would love some advice on how to fix this.

I've read through a ton of articles, and I can't seem to find a fix.

I recently purchased a Mac M1, coming from a Windows / Linux environment. After installing Firefox, it requires an icon on my desktop to run. Then, every time I reboot, Firefox no longer recognizes me. My pins, history, etc. are all gone and I have to re-organize everything again.

Can you please help?

First I was stuck in an upgrade loop where Firefox would ask me to restart to install the upgrade but then isn't upgraded on restart. So I manually downloaded latest version from the website and installed it. Now after installing I lost my current session (opened tabs). I have enabled sync so I can still see the synced tabs in my Firefox account under my device, but I don't know how to open all tabs from a particular device.

How do I open all synced tabs from a particular device in Firefox 89 on macOS 11.3.1?

Every time I try to open Firefox it asks me for permission to install Firefox Software Updater. I then say no and Firefox opens with a notification to update to the latest version. I opted out from updates but the only option available is for the Firefox to ask before updating, there is no option to opt out definitively. Is there any solution to stop notifications and installing attempts?

Thanks in advance

This morning I got a message to install Firefox V89.0. Visually this was a disaster for me. The bookmark list is now vertically spaced much wider so I have to scroll up and down the list rather than point and click. The tabs at the top of the screen which used to be easy to differentiate now blur into one. Worse still there was no easy way to back out this upgrade while I found a workaround to correct these problems? I have spent a couple of hours now, researching, exporting bookmarks, uninstalling Firefox, restarting computer, re-installing the old version (v88), Importing bookmarks, finding the icons that were on the bookmarks have disappeared, kicking the cat (metaphorically speaking), reinstalling the new tab add-in, making sue auto update is OFF. Basically a huge pain.

Is there no easy way to rollback updates? especially when the user interface changes are so invasive?

After an automatic update Firefox had a terrible surprise for me. A beyond ugly user interface. And NO WAY to fix this with a simple toggle switch back to classic mode. There are theme's available, but still it looks unusable to me. This kind of updates should be beyond Mozilla, maybe don't hire former Apple employees, the esthetics don't have to be " slick and modern"

So after a long fight with almost losing my plugins, saved tabs (100+) etc.. I downgraded successfully to 88.

Step 1 (Secure your profile) Open menu, Click Help, Click "More Troubleshooting Information" Go to the line which says, "Profile Folder" Hit open folder

Pay extra attention during these steps: Now you are browsing in your active profile. If you did this after upgrading to 89 version. Make a back-up copy of this whole folder!! Rename it back up.

Open the file "Compatibility.ini" with a text editor, and empty it. Save and close.

Download and install the previous version of Firefox, After installing don't forget to disable automatic updates.

If the profile isn't loaded, browse to "about:profiles" and find and select your profile to get al your plugins, tabs, favs, etc. back.

Its a terrible shame i need to write this down for people to avoid the frustration of a terrible update

Windows 10 changed my default browser to Chrome and will no longer let me choose Firefox as my default browser in Settings. Has this happened to others, and is there a solution?

Installation in German language under W10 Home 64bit. VCRUNTIME140_1.dll not found, installation interrupted. Firefox seems to be installed, but totally unresponsive (no files, no websites, not even parameters). Any known measures? Thanks!

Hi...for 3 days I've been unable to download anything from Hulu, Amazon Prime, Kanopy or Hoopla. Instead there's the message repeatedly about Firefox installing components to make it possible to download---anything. "Please try again later." I am not happy.

When I restart my computer firefox keep logging me out at then I need to add email and password, then my bookmarks and plugins very annoying any solutions here ?

On one computer I have deleted everything from Firefox including the folders within Apps Roaming except for one folder. There in one folder "41A66E7EE5E1" within Profiles which I cannot delete. It holds the files prefs.js and sessionCheckpoints.json which were created at 20/02/2021 and I cannot delete those.

My new installation is dated 24/07/2021.

There is nothing in the properties of those two files to suggest an issue. I do find however that when I seek to change the Property/Security to Administrator (I should be able to do that) I receive a dialog box that "the file or directory is corrupted and unreadable".

Please advise on how I address this.
