Firefox Sidebar view only shows a 'Search' window and no Bookmarks or History lists

I have never had this problem before.
I can still view Bookmarks or History but only if I select it.

I just moved to a new Windows 11 PC from my Windows 10 PC. I backed up my Firefox profile and put it on a portable drive. I loaded Firefox on the new PC and then found the folder where the profiles are. I added the profile folder from the backup. Firefox has not found it and there is no way I've been able to discern to search for it.

I added the anti-virus after trying to set up Firefox.

Here are the particulars: Firefox version 146.0.1 (64-bit) Windows 11 Application Binary: C:\Program Files\Mozilla Firefox\firefox.exe Profile folder: C:\Users\xxxx\AppData\Roaming\Mozilla\Firefox\Profiles\xxxx.default-release

Any help appreciated.

All of my bookmarks disappeared. I have followed all the step to restore from the profile folder and to restore manually. It works to a point, then I get an error message saying Firefox is unable to process the backup file (see attached image). I even tried it in Troubleshooting mode.

Recently, websites (e.g., YouTube) have stopped keeping me logged in. I've already checked all the security and privacy settings, but haven't found anything that seems to be causing this.

I hope someone can help me. It's really annoying having to log in to all the websites every day.

There’s no information on how to sign out of the AI bot itself. For example, if you use Copilot and sign in, then realize you used the wrong Copilot account, there’s no clear way to sign out and log in with a different account.

I am at my wit's end with this. checked every single post on every website but nothing works. anything larger than 30 megabytes always fails in the middle and I have to keep resuming it. It also keeps giving me the same error message "Downloads\example.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator." I have tried safe mode. I tried changing the download location, it still tells me that the .part file in the Downloads folder can't be read. This .part problem started recently after a firefox update for me. But the downloads getting cancelled for no apparent reason has been a forever problem. Is switching back to Chrome the only real solution? (I've been told this)

A few days ago my saved passwords all disappeared. I have been logging in manually and when I do Firefox asks if I want to save the password and I click yes. The password then shows up in the saved Passwords. But... in a day or so it disappears again. What's going on? I have not changed any settings.

Despite following the instructions ,I am unable to clear my browsing history. Every time I click on to "clear history," nothing happens. I am afraid to re-install the browser because my wife also has an account on the same PC and I do not want to delete here bookmarks etc.

Recently, Firefox has been slow and crashes regularly. I try to sync tabs but after it crashes and I reopen it goes back to a much older save and lose tabs I've recently opened or sometime after a crash and reopen it tries to open a window with no tabs and I lose all my tabs

Yesterday, I lost most of my bookmarks in several Bookmarks folders. These are critical to my work with several non-profit organizations. All efforts to follow Mozilla's troubleshooting advice and use the Manage Bookmarks functions to restore or import backups in my Profiles folders are met with the "Unable to process the backup file." message. I have a number of backups available, any of which could potentially resolve this issue, but nothing I have tried is working. Please help! Thanks, Shack

In settings there exists the option

"Open Firefox automatically when your computer starts up"

I have specifically chosen to disable this option; there's nothing wrong my hand.

I am perfectly capable of moving my mouse pointer to the Firefox icon and clicking it when I need to; and running on a decent spec machine with a late spec NVMe drive, the startup is near instantaneous.

I don't need or want additional Windows boot clutter.

Nevertheless Firefox periodically nags to enable this useless setting option like I maybe don't know it exists. How do I stop that ?

Whilst it's not every time I start it, I recently reinstalled Windows 11 barely a month ago. I've already been asked 3 times.

On modern systems running on high spec storage devices this seems like such a pointless option, but to even repeatedly try to push people to use it when they don't want to seems somewhat disingenuous.

Given Ramageddon where people are having to build systems with lesser amounts of RAM it seems even more unlikely that people are going to want bulky applications that they may not immediately need to be auto-loaded every time they boot their PC, before they will be able to use their pc for whatever they switched it on to do.

Is there option to disable these "helpful" suggestions ? Thanks!  :)

When my laptop is connect to a monitor via HDMI cable, the resolution on Firefox switches between what my laptop is at when not plugged in and the current monitor's resolution. It almost looks like Firefox is hiccuping between resolutions. This last for a few seconds and happens frequently within the hour. How can I stop Firefox from being confused about the resolution it's supposed to be at?

i am trying to type this message on firefox, but i have to avoid shift key not to interrupt typing. when i hot shift+some other keys like i, b, v, etc, devtools pop up. i have checked other forums, other q&a on firefox support, and concluded that the same issue have occurred to many users regardless of the os, features, extensions, various keyboards (but not the virtual one for me) or system settings. i have to type a lot in the browser, so i just choose to delete firefox until someday the issue is fixed.

There is a common error documented in https://support.mozilla.org/en-US/kb/firefox-already-running-not-responding but none of the solutions fix my problem.

I have signed out of my PC and mobile devices Done a complete uninstall of firefox on the Windows 11 machine Searched and removed ALL files on the drive associated with Firefox or Mozilla, including cache and temp Searched and removed ALL Firefox or Mozilla keys in the registry Checkdisk Used update to refresh the windows install Multiple reboots

and a fresh download and install of Firefox. And still get the "already running" error. If I wait long enough - several minutes - I will get the "crash report" screen as the background process finally ends.

Any suggestions?
